There is no way to completely reset the Digitrax DCS100 or DCS200 Command Station/Booster using Option Switches such as Option Switch 39.  Option Switch 39 resets Locomotive Registry, Consists, etc. associated with DCC equipped locos by resetting mobile decoder info (that is in the command station) and consists, routes and loco roster info.  It does not necessarily reset other Option Switches as expected. A complete reset of the DCS100 and DCS200 to factiory defaults is only accomplished by removing input power and removing the battery.  This involves disconnecting the grey terminal plug then removing the metal cover by unscrewing the ...

Overview:To reset locomotive electronics to factory defaults the user must set CV08 to a value of 08. It is recommended that this procedure be performed on the dedicated service mode programming track using direct mode programming.* Note: This is the only programming procedure that we recommend using the programming track for. All other programming should be performed on the main track using Operations mode programming.Procedure:1. Place the DCC equipped locomotive on a dedicated service-mode programming track.* Note: The rails of this track should be connected to the PROG A & PROG B outputs on the DCS100 command station.2. Set the ...

Many clubs use a DCS100/200 as a Booster in their setups.  Digitrax does not recommend using a DCS100/200 as a Booster only for this type of setup.  If you decide to do so, please keep this information in mind:   The DCS100/200 configuration is stored in memory that uses a CR2032 battery.  Over time the battery can get weak and the DCS100/200 will loose its ability to store its configuration.  When this happens, the DCS100/200 will sound 7 beeps at power up.  It will also revert back to its factory settings and once again become a Command Station.  Since LocoNet ...

The green CONFIG Indicator shows the primary operating mode of the DCS100. This indicator should be steady green blinking off briefly once every 4 seconds. This indicates that the setting for DCS100 Option Switch 05 is set up correctly. If you see 8 blinks every 4 seconds then we recommend that you change the DCS100 Option Switch 05 to closed. The DCS100 will operate correctly in either case. The CONFIG Indicator will be mainly off when DCS100 option switch 01 is incorrectly set to closed. In this case you must change option switch 01 to thrown for correct operation.

When you hear 7 beeps when power is applied to your DCS100, you need to replace the CMOS battery. The DCS100 will continue to operate, even if this battery is not present, but all your memory settings and option switch settings will not be remembered when the DCS100 is powered down. To replace the CMOS battery without losing any memory settings: 1. Remove the DCS100 input power & disconnect all DCS100 leads. 2. Open the DCS100 case:  a. Remove the two screws on the top and bottom of each side of the case. b. Slide the gray front panel off ...

Q: I have the original DCS100 with the old style non-removable wire connectors. What would I gain with a firmware upgrade? A: Early DCS100s that do not access Functions 9 - 12. If you have a DCS100 that you would like to have updated, please send it to the Digitrax Repair Department for updating. This update is a chip change only and the original style connectors will not be changed to the new style connectors. The circuit boards used for the two different connectors are completely different and are not interchangeable. The DCS100 must be sent to us for this ...

The two "POWER IN" terminals on all Digitrax boosters & command stations are the power input connections. Digitrax recommends the PS514 to power the DC200 and DB150.  Set the voltage setting on the PS514 to 16.8v or 19v.  The PS2012 can also be used to power the DCS100 and DB150.  The "Y" cable provided with the PS2012 has an embedded 5 amp current protection.  The PS2012 can also be used to power the DCS200.  The "Y" cable is not suitable for use with the DCS200 since it has an 8 amp. output. When powering your layout, make sure that all polarities and ...

Can I convert my DCS100 to a booster. I cannot find the switches in the instructions to accomplish this. Is it too old?. Can I return it for repair to accomplish converting it to a booster? The DCS100 is already a booster combined with a command station, but it can be converted to act as an expansion booster by using option switch 2 (OpSw02).

The NET indicator is a red LED that displays information about what the DCS100 sees on LocoNet. When your layout is wired correctly and LocoNet is operating properly, the NET indicator will be on and it will flicker off any time a good LocoNet message is detected by the DCS100. The table below explains the patterns you will see for this indicator.

The DCS100 automatically shuts down when the heat sink temperature rises to around 45 to 50 degrees Celsius and the OFF LINE indicator will glow red. The DCS100 automatically resumes operation when the heat sink cools down to approximately 40 degrees Celsius. The OFF LINE indicator will also be lit when there is no track status. This is normal and you should not be alarmed.

Q:  I recently split my layout in half, with a DB150 acting as a booster powering one side and a DCS100 powering the other. I'm trying to reconnect the bus feeders to the rails, which all worked properly before the split. Now when I reconnect the feeders there is no short indication, BUT when a loco goes over the insulated gap between the two sections, a short occurs. A:  This is a common issue when the first booster is added to a DCS100/DCS200 command station. MOST DCS100/DCS200 command stations come from the factory set with Rail A & Rail B connections that are the opposite ...

A slot is a memory location in the command station that holds an active decoder address.  The number of slots is the number of locomotives that the command station can support in operation at a time. When the available slots are filled with decoder addresses, trying to select another locomotive address to run generates the "slot=max" error code.  When all the slots are full you can't select another address until one is released from the system. See Clearing your Command Station's Mobile Decoder Slots below for how to prevent this from happening.The DCS100 Command Station/Booster that is included with Super Chief Xtra and other ...

You can use your DT400 series throttle with a DCS100 or DCS200 to set up routes that are triggered by operating a single turnout address to make it either c (closed) or t (thrown). Setting up and operating routes is similar to consisting locomotives because you can cause more than one unit to operate based on a single command sent to the system. We call the turnout address that other turnout addresses are “consisted” to, the TOP address. To operate a route, use Sw (Switch) mode to select the TOP turnout address in the route and move it to either closed or ...

The DCS100, 200, 240 and DB150 use several beeps and clicks that can be used as diagnostic tools that will help you debug a number of error conditions.   DCS100/200 Audible Sounds 1 Beep           DCS100/200 has powered on successfully or has sent a programming command. 3 Beeps         A loco address has been "purged" due to non-use.

The DCS100 uses several beeps and clicks that can be used as diagnostic tools that help you debug a number of conditions.

This list is the same for DCS100 & DCS200 Command Stations.* NOTE: Option Switches 36, 37, 38 & 39 have special instructions.

The TRACK STATUS indicator shows that there is voltage on RAIL A & RAIL B terminals. The color indicates the type of signal:  If it is orange the track is getting DCC signals with no analog zero stretching.  If the color is green or red then a stretched zero signal is being used to operate a conventional locomotive. When zero stretching is present, the DCC decoder equipped locomotives will read their digital commands normally and perform as commanded. If the Track Status LED is not lit there is no voltage on the track, the track power to the DCS100 may ...

Q: I connect my DT400 to my DCS100 and it works fine, but when I add a DB150 working as a booster the DT400 stops working. What is wrong? A: A number of things may cause this, so you can use the diagnostic features of the DT400 to solve this problem. Experience has proven that the most common LocoNet problem is related to pins 3 and 4. By following this diagnostic procedure, you can narrow down to the source of the problem. Starting with DT400 without a battery [The throttle has no battery for this test to assure it executes ...

Braking sections are sections of track which will cause a DCC equipped locomotive to stop automatically. The simplest way to do this is to set up a track section where the power is turned off. This has two disadvantages. First, since there is no power, the locomotive lights will be off when the train is stopped in the section. Second, the lead loco in a consist stops as soon as it hits the dead section. Other locos in the consist will push the dead loco forward. In a long consist, you could get a situation where the last loco in ...

Before sending your Digitrax mobile decoder in for repair try these troubleshooting steps to see if you can “bring it back from the dead” and save a trip to the shop and possible repair charge. As with troubleshooting anything, begin checking what could be wrong methodically. Write down your observations as you work through the list to solve the problem.The most common "repair" problem we see in our repair department is decoders that are programmed incorrectly.Many decoders we receive for repair have been programmed with CV values that cause them to seem to have a problem. The good news-bad news ...

There is an error in the BD4 Instruction Sheet, 2004 version.As a result of this error, BD4 shows no status light and no detection lights.  The solution is to connect pin 10 of the DS1 on the BD4 to a system ground such as the AX1 terminal of the DS64, Ground on the booster terminal, etc. This connection was not shown on the original instruction sheet for the BD4.

The headlights of my locomotive aren't acting properly. If you can’t control the operation of the lights in your locomotive with the DT400 (in default 128, or 28 speed step mode), be sure that the decoder is programmed in advanced 28 speed step mode. Do this by programming CV29 with a decimal value of 06.

I have this N-scale Proto A/B unit. I went to install the decoder in the A unit to the headlight, its an LED. My question is that once it was wired up and place on the track, I hit my headlight function and the light lit up then burnt out. This is my first wired decoder I ever installed with a head light. Can you tell me how to properly wire the led headlight to the DZ123 decoder so the light doesn't burn out? In looking at the DZ123 Decoder sheet, it suggests that I check the Decoder Manual for ...

Flashing ditch lights can be set up with several CV's. Using 1.5 Volt Bulbs or LEDsIf you use 1.5 V bulbs, you must install a current setting resistor with a minimum value of 100 ohms for each bulb.Typically a 560 ohm 1/4 watt resistor works well for a grain of rice bulb and a 250 ohm 1/4 watt resistor works well for a grain of wheat bulb.Lower resistance values will increase the lamp brightness. If you use LED's be sure the polarity is correct when you hook them up & install a current setting resistor for each LED. Typically a ...

I'm looking to wire Tortoise switch machines on a DS64. When the track switch is thrown I want to power 1 color light (non-LED). When the track switch is closed, power a different colored light. Is this possible using the DS64 inputs or the Tortoise connections? The DS64 does not have separate connections for indicator lights for trackside or for a control panel. However, indicator lights can still wired to work with the DS64. Tortoise or other slow motion swith machines can be wired in two different ways. If using LEDs, a two leg, bipolar LED can be connected in ...

When the command station is in the Locomotive Mode,Lo, the numeric keys are used to enter loco addresses. When the command station is in the Switch Mode is Sw, the numeric keys are used to enter switch addresses.In ...

You can automate grade crossing signal lights with block occupancy sensors. Install a BD4 to detect track occupancy as shown in the figure below. Other than removing the Op Sw35 commands from the routes used in the related article example, there is no additional programming needed for the DS64. Sensor operated occupancy detection requires that all rolling stock be equipped with resistor wheels for proper detection or that the detection section is longer on each side of the RR Crossing than the full length of a train since only the locomotive will draw current. A lighted caboose on the end of ...

The Super Chief can be used to operate routes. A Route is a group of turnouts and their specified positions that will be triggered by the activation of a single "TOP" switch address to a specified position. The DCS100 Super Chief supports up to 32 routes. Each route consists of a list that contains a TOP turnout address and its position (c or t) and up to 7 other turnout addresses and their positions. Routes are stored in the DCS100's memory and can be operated by any throttle in the system that can send switch commands. Each of these 32 ...

Life-Like Proto 2000 locomotives with number board lights have the number board bulbs wired to their 8-pin DCC plug using pins 4 and 5. This causes no problems with DC operation but causes a path from the rail pickup to the gray motor lead when a decoder is installed resulting in erratic operation and decoder failure.This is a known problem in the Proto 2000 GP60, SD60M and LifeLike GP38-2.  The DH165L0 uses a current limiter set to control one incandescent bulb on the front (FOF) and one on the rear (FOR) and putting the removed number board bulb on either ...

FX3 decoders have motor isolation protection. If the decoder senses that the motor is not isolated, it will not run the motor. In this case, you will be able to control the loco’s functions but the motor will not work.FX decoders will blink the loco's lights when power is first applied to the decoder to warn you of a short circuit in your installation. If you see the lights blinking, immediately remove the loco from the track, locate the short circuit and correct the problem before proceeding. Do not leave the loco on the track with blinking lights because eventually, ...

DCS50 Zephyr can control Functions F0 - F8. Most DCC mobile decoders have function outputs that you can use to control lamps, LEDs, sound, smoke generators and other on/off devices installed in your locomotives. Most locomotives made today come with a head light and sometimes with a rear light, too. With DCC, these are controlled by the decoder’s function outputs. You can also install additional DCC controlled lighting such as cab lights, Mars lights, ditch lights, rotating beacons and others on your locos.

Does your throttle say slot=max ?This means that the system's capacity to handle operating locos is full. The DCS100 can run up to 22 or 120 addresses at the same time. If you have the slot=max message, be sure that all locos that are not running are released from throttles or set DCS100 OpSw 44 to closed to increase the number of address slots available to 120. The DCS100 command station that comes with all Genesis, Empire Builder and Chief series starter sets are set with a factory default of 22 slots.  So, once you begin to operate significantly more locos, you may need to ...

What's the best method to handle structure and street lighting with a DCC layout? If I put in bus wiring for my lighting can it interfere with the DCC signal? Unless you have stationary decoders that control the structure and street lights, there is no need for connecting these lights to your DCC wiring. In fact, doing so will add additional power consumption without any of the advantages of command control. These additional power consumers take away available power for your locomotives, controlled cars and stationary decoders. Should I use a completely different power source like an old power pack? ...

Digitrax decoders have outputs that can control lamps and other on/off devices installed in your locomotive.  These are called functions.  Functions are things like: lamps, sound units, smoke units, etc. All Digitrax decoders are equipped with two or more function outputs that are used to turn functions on and off.Decoder function outputs can be:1.   Leads (wires) attached to the decoder that are used to hook up external functions.  See Table I below for wire color codes used on Digitrax decoders.or2.   Pre-wired function outputs that hook up by just plugging in the decoder. This is the case for decoders that ...

If your throttle says "slot=max", this means that the Super Empire Builder's capacity to handle operating locos is full. The DB150 can run up to 22 addresses at the same time. If you have the "slot=max" message, be sure that all locos that are not running have been released from throttles. This will free up room inside the DB150 for other locos to run. A DCS100 command station can run up to 120 locos so, if you are having this problem often, you should consider adding a DCS100 to your LocoNet system. To Release Locomotives 1. Use the throttle to ...

Q:  I have a Digitrax Chief system. I wired the programming track as per the manual, using PROGA and PROGB outputs on the DCS100. I turned on the system and checked the track voltage with a Tony Trains RRamp meter, the mainline read 14.2 volts. The programing track did not read anything. I then checked the two wires coming from the DCS100 and they did not have any readable signal. A:  The programing track connected to PROG A and PROG B will NEVER have track power on except the very instant the program message is sent.  So, you would not ...

When DCC locos enter a brake section with braking on, they will receive braking commands from the command station instead of normal DCC operating commands. DCC locos in this braking section will come to a stop. When you throw the switch to allow normal DCC commands, the DCC locos will resume normal operation. Once the DCC loco has left the brake section under normal DCC power, simply return the switch to the break position so that the next DCC loco will stop in the section. This is useful if you want to have trains stop at stations around the layout ...

Q: I read in the February 2008 "Scale Rails" on page 11 that I need to add some "High Frequency Filter" gizmos on my layout to make my trains run properly. I have been using Digitrax equipment for 12 years, do I need to make these changes? A: We do not feel that this is necessary. With modern, well designed decoders, almost any combination of transmission-line ringing and other mismatch effects described in this article are completely filtered and ignored by the decoder. This is a superior solution rather than trying to design filters for unpredictable limiting cases of wiring ...

Remove the 8 pin dummy plug from Lifelike Proto 2000 light board.Before installing the decoder in the locomotive, unsolder the yellow wire from pin 2 and re-solder it to pin 3 (empty pin) on the decoder harness plug board.  We strongly recommend that you mark the decoder and/or harness so that you will remember that you have modified it.  If you use the decoder and/or harness modified in this manner in a different locomotive, your lights will not work correctly. Plug the decoder and harness into the light board in the locomotive.Program CVs as follows:  CV33 = 001, CV34 = ...

The DZ125 is set up at the factory to control two function outputs. The DZ125 is configured to control the forward and reverse lights on the locomotive through the white lead and yellow lead using Function 0 (F0F-forward and F0R-reverse) for directional lighting. Both function outputs can be easily set up with Digitrax FX3 lighting effects or as standard on/off functions with the following operational qualifiers: 1. Forward or Reverse direction of travel, or 2. Whether F0 is on or off, or 3. Both direction of travel and whether F0 is on or off, or 4. Whether the locomotive is ...

The SE8C can drive position light type signals such as those used by the Pennsylvania Railroad and the B&O RR and the N&W RR. Leads from the signals can be soldered directly to the pads on the Signal Mast Base (the Terminal Strip Mounting Kit can also be used for interfacing your signals with the system.)You can use either common anode or common cathode signals.  We recommend that you use either all common anode or all common cathode signals on your layout for consistency in the set up procedure on your layout. If you are using the terminal strip option ...

This note addresses the installation of an H0-Scale wired decoder into Bachmann Plus ABA F-7s; it calls for using a DH140, which has been retired.  Current decoders such as the DH123 or DH163 or similar wired decoders can be used. Just finished up doing a few HO Bachmann Plus F7's, ABA's to be exact. Thought maybe some of you might be interested in how the DCC conversion went on these.They are an easy conversion!1.  The full stall current for these ranged from 500-700 ma for each loco . I selected Digitrax DH140 for the A units and a DH120 for the B ...

CTX/CTY throttles allow you to have up to 4 separate throttles controlled by 4 different operators rather than 4 throttles controlled by one operator as in the CT4 that comes with your Challenger Set. Digitrax provides these instructions so that you can build your own throttles to your own specifications. You are free to choose any knobs, buttons & cases you like, the ones on the parts list below are just suggestions. These throttles give you the option of expanding your operations cost effectively. The CTX throttle controls speed & direction for one train in the operating group & can ...

I'm trying to install a DH123D decoder in a Life like P2K PA loco and make the mars light work. HELP! Because the DH123D is a two-function decoder (front headlight, rear headlight), it may not be the best decoder choice for this locomotive. In practice, some PA's had only one headlight, thus there would be no Mars light. The DH123D would be an appropriate choice for those locomotives. Typically, eastern railroads would just have one headlight; think Pennsy and Southern Railway. Western railroads, because of higher train speeds, often used warning lights such as the Mars Light or Pyle Gyra-Light; ...

This article courtesy of Ross Webster, which dates from an earlier era before Bachmann made accommodations for DCC installs:There may be others ways do to this conversion, but this is the way I found using the Digitrax DG380 (any DG wired decoder can be used for this installation) DUE TO SOME OF THE FRAGILE ITEMS ON THE SHAY I WORKED ON A FOAM PAD SO THERE WAS NO DAMAGE TO ANY OF THE SMALL PARTS.I first tested the electrical items and made the following determinations.Free running for the two trucks was .8 amps, total. Stall, was 4.6 amps total for both trucks. Smoke ...

Our thanks go to Digitrax operator Aksel Suarez of Chesapeake, Virginia for sending this tip on how to install a Digitrax decoder in the Walthers GP15, called by some prototype railroaders a "Geepette" or "Cheep Geep". Use a DH165A0 decoder to replace the existing light board. Remove the plastic clips that hold the wires to the light board. Once the light board has been removed, place a piece of electrical tape on the metal frame to isolate the decoder from the frame and prevent a short circuit. The wires on the locomotive to the motor and lights do not follow ...

The PR4 will only “light up/power ON” when it is connected to a computer via USB.  Simply connecting the PS14 will not power the device and cause any lights to come on. Please follow the complete PR4 installation instructions consisting of PR4 Driver and Software Installation and PR4 Hardware Installation to power and test your PR4. Using the PS14 power supply is only required when using the PR4 for Sound/Decoder programming.

The DH163 series decoders are set up at the factory to control six function outputs.

CAUTION: When adding function wires, be very careful that the wires you add do not come into contact with any other pads or components on the board where they might create a ...

The DT402 & DT400 can program and readback CVs with the DCS100 or DCS200 (Super Chief) or the DCS51 or DCS50 (Zephyr). You must use the programming track for this unless you are using Ops Mode with transponding installed to allow for Ops Mode readback.  Infrared and simplex radio throttles must be plugged in to LocoNet to read back CVs & their values.  Duplex radio throttles do not have to be plugged in for reading back CVs.Systems with a DB150 command station (Super Empire Builder) are not able to read back CV Values programmed into decoders. To read back CV values: 1. Place the decoder ...

Function Controls F9-F12 Some Broadway Limited Locomotives use Functions F0-F12 when running in DCC mode.  In some cases F9-F12 do not respond properly.  To remedy this problem, simply reset the locomotive to the factory default setting per the Broadway Limited Instructions you received with your locomotive. Note:  F9-F12 are accessible on the DT400 throttle when used in conjunction with the DCS100 command station.

I have a Zephyr control station and I would like to set up a Braking District as shown in your PDF sheet in the Basic DCC issue section; you show a DCS100 connecting through a modified LocoNet cable to a DBxxx booster -- can this same setup be used with a Zephyr system? No. The braking district described here uses Super Chief and a second booster to create a braking district. Super Chief is configured by toggling OpSw47 and connecting it to a second booster that is properly configured. Because Zephyr does not have an available OpSw47, and because there ...

Is it possible to use UP3 with a Super Chief system?Yes. Both have LocoNet in common, so the signals produced by the DCS100 Super Chief go though LocoNet to all devices that can connect to the LocoNet, including the UP3.

I have a DCS100. I do not understand why my DT400's speed increases (all the way up to 99) sometimes when I plug it in. Also, sometimes the Loco number (when selected when this is taking place) will increase too. There is no control enabled when this is taking place. If I plug in a DT100 it operates normally. One of the buttons on the DT400 may be stuck, leading to this behavior. Take a look at the control panel of the DT400 and you will probably see this stuck button since it will not be in a fully returned ...

Digitrax SoundFX Decoder Troubleshooting Guide This troubleshooting guide assumes that you are working with an operating Digitrax system that is able to run trains and that the locomotive you are troubleshooting is operational and has a Digitrax sound decoder and speaker installed correctly.  If there is no sound, first make sure the decoder is not muted: Press the Function 8 (F8) key, and make sure F8 is OFF.  Function 8 is used to toggle between sound active (F8 OFF) and mute (F8 ON). If there is no sound and the locomotive won’t move when the address is selected on your ...

Q:  Is it possible to use Digitrax equipment to wire the Kato N-Scale Automatic Track Crossing? If so, how do I do it? A:  The answer is a probable "No", but there may be a workaround. The Kato, USA website notes: Some Unitrack components such as the Automatic Crossing Gate and 3-Color Signal were designed with DC operation only. So, the official position is that that these devices don't work in the DCC environment. However, we are not above speculating on how to do this, nor are others. An online web search turned up this bit of message traffic by ...

  This example is a small yard with a crossing signal at its entrance. We will use independent turnout addresses to demonstrate the flexibility that the DS64 offers. Here, route (track) 2 3 and 4 will activate the blinking light when set and the deactivation is done by resetting to route 1, the main line. The advantage of this setup is that you can easily do operating RR Crossing lights without the need for additional equipment for block detection. The turnout output utilized for the RR crossing operation is simply integrated into the route setup. In addition to the route ...

This Atlas Snap-Track layout appears in the Atlas Model Railroad Company's book "Beginner's Guide to HO Model Railroading". It includes a reversing section which can be controlled with a Digitrax AR1. DC Control For DC operation, Atlas specified an Atlas Controller (for the reverse loop), two Atlas Selectors (to control eight track segments) and seven controllers for the railroad's turnouts. DCC Makes Things Simple With DCC, the wiring of this railroad is considerably simpler. Because each locomotive has a unique address, the section insulated gaps and the two Selectors are not necessary. Likewise, the Controller is replaced with the AR1 ...

Decoders with FX function features have 4 user configurable, independent special effects generators. All current production Digitrax Decoders use FX3 functions so this article is not applicapable to these decoders.

Railroad signaling works based on detection of trains on the railroad.  If a train is detected, then the signal system goes into action, setting up indications that let show that the track section is occupied and warn other trains that the section is occupied.  At a grade crossing where a railroad and a highway intersect, the presence of a train starts the crossing signals and lowers the gates in time to stop highway traffic so the train can pass.In the case of real railroads, detection is easy, since the rails are naturally insulated from each other and either a locomotive or ...

Each DCC decoder that is installed in a locomotive is assigned a unique address. To select a locomotive and run it on either throttle, you must know the address assigned to the decoder. Digitrax decoders are set up at the factory with the “default” digital address of 03. This means that when you take a Digitrax decoder out of the package and install it in your loco, you can select address 03 on your throttle and run the decoder. The first Configuration Variable (CV) programmed by most DCC users is the decoder’s address since it is not very useful to ...

1. Read the instructions FIRST and PLAN your installation. Have the proper tools on hand. 2. Choose a locomotive that runs well on regular DC. 3. Choose the appropriate decoder for your installation. 4. Test the decoder before installation. 5. Carefully disassemble the loco. 6. Isolate the motor! 7. Follow the decoder's wiring diagram or installation instructions. 8. Test the installation first on DC then on DCC. (If the lights are flashing the first time you apply power, remove the loco from the track and locate the short circuit in your installation.) 9. Customize your decoder by programming individual CVs.

QUICK INSTALLATION Notes for users with decoders not made by Digitrax:1. The DCS50 command station operates in 128 speed step mode. If you are using a locomotive with a decoder that does not have 128 step capability you will have to adjust either the decoder or the DCS50 so that both are using the same number of speed steps to communicate. We call this procedure status editing. You can status edit each individual decoder or you can change the DCS50’s system default by setting the DCS50’s Option Switches 21-23 and run all of your decoders with fewer speed steps to ...

  I have a 14x24 foot room with a shelf layout on two levels. 1st level is about 24 inches with two main lines and some industries, a moderate freight yard, moderate intermodal facility and passenger station. The second level is 18 inches and will contain one and two main lines with mostly industries. This would qualify as a "medium to large" model railroad. I would like to have 1-5 operators with 2-10 trains running at one time as permitting. At least four Universal Panels would give all operators full access to LocoNet as necessary. At least one UP each ...

1. Carefully remove the locomotive’s shell from the frame. Notice the orientation of the shell to the frame so that you can reinstall correctly. 2. The DZ125 has 6” wires that you will solder directly to the appropriate connections inside the locomotive. The smaller size allows the decoder to be easily installed in a variety of locomotives. The bare ends of the wires are wired to the motor connections, power pickup connections and the lights according to this standard. Note: Avoid stressing the solder connections of the wires to the decoder board. If a connection is broken, carefully solder the wire ...

The DS64 is a powerful stationary decoder. If you have tried to program this stationary decoder and are having problems, there are several things that you can do before contacting Tech Support for further help. Is the DS64 receiving enough power? The DS64 can be powered in several different ways. Although it is possible to power the DS64 from track power, this has been a source of problems for many operators due to low voltage. This typically arises on a railroad that is using power in excess of the capacities of its power supplies. Have you programmed all four addresses ...

CVs are decoder memory locations that hold loco address, operational  configuration and performance settings. Adjusting them to customize the performance of a specific locomotive is one of the main advantages of DCC over DC running. - Doug StuardThese are special storage locations or "pigeonholes" in your mobile decoders. By programming various CVs, you can control each decoder's performance characteristics. CVs store information like the decoder's short address, long address, start voltage, mid-point voltage, loadable speed tables and many more. Once you have programmed these characteristics, the decoders "remember" them until you change them again. Most manufacturers use a similar set ...

I have an old Diamond Scale turntable; this turntable uses a rotary switch to select which stall or track you want to align the table with. It is basically a closed connection, or relay connection to select the track you want. I was wondering if it was possible to use the DS64 to create a closed connection (relay output) to activate this connection for the turntable position. Basically I want a relay output from the DS64 to be addressed by my DT400. Using throttle control This should be fairly easy, but not in the way that you envision it. The ...

If the function you want to operate does not respond, check the following:1. Is Track Status [4] on? If not press the POWER key to turn it on. 2. Did you select the correct loco? If not, select it now.3. Is the function you want to use installed in the loco? If not, you may need to install it. Most new locos have a head lamp/backup lamp installed, but most do not have any additional lights or sounds installed.4. Change the position of the Direction Control Lever and see if the lamp comes on in the other direction. If the ...

Q:  Using Digitrax systems to program an MRC AD310 decoder is especially confusing because the MRC Command 2000 uses several "switches" and "levers" rather than standard CV numbers. A conversion chart for the 10 possible MRC engine addresses would be a wonderful help to us old-timers. A:  The documentation available from the manufacturer of this decoder is incomplete. Many older decoders such as this one are not able to recognize all the digital packets in use by more modern DCC Systems. What we have learned is the MRC AD310 is: Programmable up to 127 (1~127) locomotive addresses Programmable for either 28 or ...

Remove the 6 pin analog shorting plug and in its place insert the DZ125IN/DZ126IN decoder with the correct pin-1 orientation. (There also is a small numeral "1" on the bottom of the DZ125IN near pin-1.) The DZ125IN has 6 pins that insert directly into the 6 pin socket (NEM 651 type) on the locomotive’s PCB. The DZ125’s small size allows the decoder to be easily installed in a variety of European locomotives. For the Kato ...

Configurable strobes are set up using CV's 49, 50 and 61. Configurable strobe function leads can be programmed with a limited number of simulated lighting effects similar to FX effects but without as many options.

How does DCC work? You use a throttle (cab) to tell the system what you want a train to do. The throttle sends the information to the command station. The command station makes a digital packet out of the information and sends it to the booster. The booster* adds power to the digital packet and sends it out through the rail. The decoders in all locomotives (even those that are not running) read all digital packets, and decipher them to get the address contained in the data packet. If the packet address matches the decoder address, the decoder uses the ...

Q: Can you have two command stations on the same layout? A: No. If you try and run with two command stations you will experience what we usually refer to as "shocking, horrifying results." Two command stations on a single layout is often a problem with modular layouts. You can disable the command station capability in Digitrax Command Station/Boosters so that you can use them as boosters only to add more power to your layout.For the DCS100 to disable command station mode:1. Set Op switch 2 to "c" 2. Set Op switch 5 to "t" 3. Set it to auto ...

LocoNet System ArchitectureDigitrax LocoNet is a Peer to Peer local area network (LAN) designed specifically for model railroad operation.  System architecture is the biggest difference among DCC systems, the way the components of a DCC system communicate among themselves. LocoNet wiring is cost effective, flexible and expandable to accommodate almost anything you want to do with your railroad today and in the future.System ExpansionHere are some of the expansion possibilities available with LocoNet. With Digitrax LocoNet your DCC journey starts at the Main Station with your first “starter” set. From there, it’s up to you. You can add:  Mobile decoders ...

  CV29 is assigned a single value which chooses a combination of specific effects: 1. Speed step control. 2. Speed table On or Off. 3. Analog mode conversion On or Off. 4. Normal Direction of Travel (NDOT). 5. 2 digit addressing or 4 digit addressing. Analog Mode Analog mode conversion is very convenient if you plan to run your Digitrax decoded locomotive on regular DC layouts. With analog mode conversion enabled, the decoder will automatically begin operating as a DC locomotive when no DCC signal is detected by the decoder. This means that if you place your Digitrax decoder equipped ...

Resetting Factory Defaults You are unlikely to encounter a problem that will require a factory reset. One such instance may occur if you set a password for your Duplex Group name and forget what it is. Resetting to factory default condition is an easy way to correct the situation. Note: If you have more than one UR92 in your layout, you will want to disconnect all of them to do a full factory reset on each unit as follows. Once they have been reset, reconnected to your LocoNet, and allowed to renegotiate a common Group name; you can change the ...

Digitrax Complete Train Control By Zana & A.J. Ireland Digitrax Complete Train Control makes reliable, realistic train operation and simplified layout wiring a reality. Digital Command Control is incorporated within the Digitrax system to let you control multiple trains independently on the same section of track without blocking. In the real world, engineers control the speed and direction of real trains. Engines operate under their own power independent of the track. Each engine has its own motion characteristics like how fast it speeds up (acceleration) and how long it takes to slow down (deceleration). A locomotive's performance is influenced by ...

The layout uses twenty-eight turnouts on the mainline and an additional eleven turnouts in the yard. Each turnout is powered by a Tortoise slow motion turnout motor. Each of the twenty-eight mainline turnouts has three dwarf signals associated with it. The aspects of the signals are shown below. The indications of the signals are: Green = Proceed Yellow = Proceed with caution Red = Stop Each signal has one head with two LEDs. There are also thirty-eight mainline block signals (red/green) that are controlled by heavy duty single pole double throw relays. This makes a total of 122 signals. Since ...

If you have more than four turnouts, you will need to program the addresses.The DS64 has 4 Output pairs labeled 1R & 1G, 2R & 2G, 3R & 3G, and 4R & 4G.  The DS64 is shipped from the factory with these outputs programmed as Switch Addresses 01, 02, 03, and 04 respectively. You can set the Switch Address of each of these four Outputs to any value from 01 - 2048.NOTE:  During this procedure the DS64 must be connected to an active LocoNet with an active command station.1. On the DS64’s control panel, press and hold the ID button ...

  What is the difference between programing on the layout using Track A and B and using a dedicated programing track using Pgm A & B. Is there a difference in voltage, packets, protocol between the two? Programming Track Broadcast programming, also called service mode programming, uses a programming track. The programming track is electrically separate from the rest of the railroad, and is connected to the "PROG A" and "PROG B" terminals of your DCS100/200 or Zephyr (Xtra) command station.One major advantage to a programming track is that many systems can read-back the Configuration Variables (CV's) that are in ...

  I have an "M" shaped 250 square foot layout with 500 feet of track and twelve locomotives. What Digitrax equipment would I need? You don't say what scale this railroad will be modeled in, which is important since the locomotives in smaller scales draw less current than larger decoders. However, for purposes of estimation: Twelve Locomotives. Each locomotive is going to draw, at the very least, 5 MA for the decoder. If it has LED lights, then it will typically draw 15 MA more; conventional light bulbs will draw 50 MA. A typical H0 locomotive will draw 600 MA ...

On/Off Switch. Integral cooling fan. Design coordinated for use with Digitrax products. One "Y" Cable (P/N YC52) Included for convenience with dual 5 amp protected outputs All secondary devices must be properly fused on their power input leads for their rated capacity. For example if you intend to use the PS2012 to drive a 5 and an 8 amp booster, you must input fuse these devices for ...

Programming is the process of setting the configuration variables (CVs) in your decoder to the appropriate values that will make the locomotive perform the way you want it to.  The first CVs that most people change are those that set the locomotive decoder's address.  The mobile decoder in your locomotive usually comes pre-porgrammed to a factory default address of "03".  Once you add a second locomotive, you will want to change the this new locomotive to another address.  Not doing so will result in both locomotives operating at the same time when you send commands to address 03.Likewise, there are a ...

The term smooth DC is used to describe the power provided to the layout by conventional model railroad power packs (analog transformers). Traditional model railroad power packs convert household line current into 12-18 volt current to power your model railroad. Voltage is supplied to the track, and as the voltage increases, the speed of the locomotive's motor increases, which makes it run down the tracks at faster speeds. Some power packs put out only AC (alternating current), while others put out DC (direct current) and AC (for accessories such as track switches and building lights). AC powered trains tend to ...

I am putting the finishing touches on my 10 x 20 foot H0 railroad.

BD4 Output Each BD4 is situated between the PM42 Power Manager and the railroad. The DCC signal passes from the DCS50 Zephyr, through the Power Manager, through the BD4 to the track to the locomotive. When a locomotive (or equipped car) is present in a track segment, the BD4 also sends out occupancy information, in two ways. Occupancy Information Output LED1 The LED1 10-pin header is for testing the status of power to the rails and block occupancy with the LED indicator which is included with the BD4. The LED1 can also be used for panel indicator lights using LED's. ...

  This document outlines the power requirements for Digitrax LocoNet accessories.  To simplify wiring, Digitrax recommends providing individual power supplies for like accessories.  For example a power supply or power buss which only powers the PM42s.  A power supply or power buss used solely to power multiple DS64s.  UR9x and UP5 panels can be daisy chained provided adequate current is provided to properly power all the panels.  Through the use of individual power supplies, the chance of Ground Loops or sneak paths back to ground is minimized.  Using individual power supplies will also make troubleshooting much easier.  Many Digitrax LocoNet ...

Decoder Lock lets you use more than one decoder in a locomotive and be able to program their CVs separately.  This is a manufacturer specific CV.  The instructions provided here work for Digitrax decoders.  If you are using decoders from another manufacturer, please consult your decoder instructions for how this feature works with the decoder you have installed. For example, if you use a mobile decoder and a sound decoder together in your locomotive, you can use the same mobile decoder address during operation and when programming you can unlock only the one you want to program. Since all decoders with the ...

Q:  I have a DH163D decoder. How do I program it so the Mars light works? A:  Any function output on Digitrax FX decoders can be set up for any FX effect by programming its associated FX CV to the appropriate FX CV value. For example, if CV52 (the FX CV for F2), is programmed with a CV value of 034, the violet wire F2 function output will be a Mars light when F2 is turned on for this decoder address and the decoder's direction is forward.

Wiring lighting without burning out bulbs on the first try. Need some info on which bulbs and boards need drop resisters installed and why. The new DH165 series have eliminated the mystery since they work with either LED's or with conventional lamps without adding resistors.

One of the basic problems encountered with command control systems is when things simply are not working.  Period.  Even after vigorous exhortation on your part, and perhaps even some enthusiastic train table banging, nothing is running.  At this point, it is time to gather your wits and your patience for a debugging session.   The first step to determining how to proceed is to determine if the problem with the electronics or with the layout?  The tendency is to blame the electronics, after all it is a black box.  But don't jump to conclusions so quickly! Be patient and follow the ...

Q:  Your recommendation is to have a DB150 booster at no more than 50 foot intervals. Will one booster handle all track in that 50 foot area, i.e. a passenger terminal throat with many turnouts and switches? A:  The "50 foot intervals" applies to the maximum distance which boosters can be located from each other. This is a conservative recommendation.  You should consider how much power will be consumed in a district when locating boosters around the layout.

Needs a comprehensive answer.  There may be one somewhere else already.  Z.This is from the decoder manual and does not answer the question:A 12 or 14 Volt lamp run directly without resistors will be less sensitive to voltage fluctuations. For regular 12 to 16 Volt lamps that draw more than 50 mA when lit, we recommend that you put a 22 to 33 ohm 1/4 watt resistor in series with the lamp leads. This will ensure that the lamp "start-up currents" (up to 10 times normal current draw) do not overload the outputs.If you want, you can estimate things by ...

In response to questions about the differences among the DCC systems that are currently available from different companies, I offer the following comments & observations. You may have heard that all the systems are pretty much the same or you may have seen “comparison” charts in various DCC companies’ literature, in magazines or “analysis” on the Internet by “impartial observers.” Unfortunately, it is almost impossible to break down the system and company differences on a simple chart & the people who write the “impartial analysis” are usually not really impartial. As you read these comments, please keep in mind that ...

Most HO, N & Z Scale model locomotive motors and lamps are designed by the locomotive manufacturers to operate at full speed at 12 volts DC on the track. Digitrax recommends running your DCC command station and boosters at the lowest track voltage possible that provides acceptable operation. The “N Scale (12V)” setting on Digitrax equipment works for most HO, N & Z scale layouts. Some DCC systems made by other companies supply more voltage to the track and are not adjustable. If the track voltage applied exceeds the operating parameters of the locomotive and its lamps, it is possible ...

The Kelana Jaya Rail Line model layout uses WinLok 2.1 running on a PC under Windows 98 to operate the trains, turnouts, signals and to use the feedback from the block detectors for train control. This equipment was configured and programmed to PUTRA's specifications by Dr. Hans R. Tanner of DigiToys Systems. PUTRA specified the following capabilities for the control system used for the simulation: 1. Run eight trains at once in any combination of automated or manual control. 2. Define specific routings and be able to assign automatically or manually any route to any train at the time the ...

In earlier generations of model railroading, the reverse loop (reversing section) was the bane of many model railroaders. As the rails of a track come back upon themselves, an electrical short circuit is created. In the analog control world, the solution is to use toggle switches and special wiring to allow the locomotive to move on to the next block. Electromechanical solutions relying on relays and track detectors can also be used to automate reversing on an analog layout. The wye is another example of a reversing section on a layout. One of the advantages of digital command control is ...

This application note is courtesy of Michael K. Perrin, and addresses the installation of an N-Scale decoder in the Bachmann F40PH (now discontinued).  This note calls for using either DN93 or DN140, both of which have been discontinued.  Current decoders such as the DZ125 or DZ143 and other similar N scale decoders can be used.1) Cut a place for the decoder in the back recess in the frame. Because this is a "sandwich" frame there is no room for the decoder without using a saw or Dremel tool to make a cavity for the decoder. (This is the hardest part of the ...

Good DCC practice means good planning for the electrical needs of the railroad. Here, we talk about the power needs of the Texas & Southwestern. Anticipating Power Consumption The core of the Texas & Southwestern's DCC control system will be the DCS50 Zephyr, which is very appropriate for a small railroad. Zephyr has 10 "slots", memory locations in the command station each holding an active decoder address. Rated at 2.5 Amps, the Zephyr should also be enough to handle the power needs of the railroad, but if more power is needed, then T&SW can easily be expanded with an additional booster ...

1. Carefully remove the locomotive's shell from the frame (Figure 1, below). Notice the orientation of the shell to the frame so that you can reinstall correctly. 2. To remove the Atlas MP-15DC standard lightboard you will need to loosen the frame screws as shown in figure #1. After the frame halves are loose enough, the standard light board can easily be removed by moving the light board to one side and tilting the lightboard out. 3. Installation of the DN163A3 decoder is the reverse of the removal sequence. With the frames halves still loosened, slide the DCC decoder into ...

Installation: Figure 1 shows the general arrangement for connecting one or more LNRP's to configure a LocoNet based system for operation. Note that the LNRP's drive the power and Railsync signals on the "standard" LocoNet cable segments, so each LNRP should have a DC input of +15V to +18V at up to 250mA supplied on the side DC power jack. Note that the shaded cable connections are made from the protected network side connections of the LNRP units to the components that are on the "protected" or high reliability part of the System. The other solid cable connections are the ...

  The most common problems on the layout that will impact your DCC system are electrical short circuits. If you find that you cannot get the Track Status light on your command station to come up, or there are numerous beeps from the booster, then disconnect one of the Rails from the booster and the problem should be apparent. There is an electrical short in your layout wiring. The quarter test is the BEST diagnostic tool that you have! With your DCC system up and the Track Status ON, create a short circuit across the rails of the layout every ...

We recommend testing your new SE8C prior to installation on your layout. The following testing procedures will help familiarize you with the general operation of the SE8C. Track power needs to be ON, a working LocoNet connection and a throttle or PC running DCC control software. Pre-Installation Set-Up 1. Solder one wire from a 12V AC or 15V DC power supply to Pin 3 and the second wire from the power supply to the Pin C on the 44-Pin edge connector; this powers the SE8C. Digitrax manufactures the PS14, which is appropriate for this installation. Multiple SE8Cs can be powered ...

Model railroad layout signaling is just as complicated as real railroad signaling. This is an example of how signaling might work on a small oval layout.  Once you understand how the signals work together in a simple setting, you will be better equipped to tackle signaling on your layout. The layout is a simple oval with a passing siding. Here are the locations of the individual signals: This railroad has four Absolute signals, two Dwarf signals and two Permissive signals.The four Absolute signals and two Dwarf signals protect not only the main line & the passing track but also the two turnouts ...

Current production Digitrax decoders use the following numbering system: The first character means that it is a digital decoder. This is always a “D”. The second character indicates the decoder’s physical size. This is based on the smallest "scale" the decoder is designed to fit. This will be a Z, N, H, or G. The third character is the current rating of the decoder. This will be a 1, 2, 3, 4 or 5. We designate 1.25 & 1.5 amp decoders as 1s and 3.5 amp decoders as 3s for simplicity. The fourth character indicates how many functions, including directional ...

  Q:  On my PR2, I have been getting the red light and message saying COM Port Paused a lot when trying to read CV’s. A:  This operation is normal. Whenever you bring up any of the auxiliary menus such as Soundtest or CV editing, the main Soundloader screen pauses its communication with the PR2 so the auxiliary menu operation can take place. When in the normal main screen, the program is constantly talking to the PR2 so it must be paused to allow these other activities to take place. Unless you are not able to read/write CV's, this should ...

Function-only decoders allow you to add additional functions to a locomotive with an existing mobile decoder.  Additionally, function-only decoders allow you to install lighting in passenger cars, as an example.Function only decoders also are used to add Digitrax transponding to early model Digitrax decoders and decoders from other manufacturers that do not have this feature.

DG583S - Function Outputs 1. Function outputs are rated at 2 Amps each. Do not exceed the decoder’s 5 Amp total output rating. This total includes the motor current and total of all function output currents.2. To use a function output with an inductive(coil) type load, see the Digitrax Decoder Manual for more information to avoid damage to the decoder.3. See the Digitrax Decoder Manual for full details of wiring 12-16V lamps, 1.5V lamps, and LEDs. Lamps that draw more than 80 mA when running require a 22 ohm 1/4 watt resistor in series with the directional light function lead ...

Dispatching is a special way of offering a locomotive address to a UT1 or UT2 to run. The address is set up and then dispatched to the system to be acquired by the next throttle that presses its ACQUIRE Key. This is not the same as releasing a locomotive address from the system. Releasing an address clears it from the locomotive slot to make room for another locomotive address to be run by the command station. 1. Set the address selector switches to address “99” then press the “ACQ” button. 2. The Status LED will light green showing that you ...

"Turnout" is a civil engineering term for what railroaders call a "switch".  In the model railroad environment, we often use the word turnout to avoid confusion with the electrical term "switch".  On the railroad, throwing a switch usually only means one thing, while "Throw the switch" on a model railroad could mean operating a light switch.Probably the best answer is to consistently use one type of turnout.  The notion of a "DCC Friendly" turnout is a myth; the standard answer in the past has been: "If it worked on DC it will work on DCC". In the end, which turnout ...

The UT4 series, UT4, UT4D & UT4R are "traditional" style throttles.  The UT4s were developed from a specification submitted by Digitras users through the Digitrax Yahoo group. These throttles were designed by operators for operators.  They are also great for beginners because of their intuitive controls and reduced feature set. By not offering all the bells and whistles, beginners can run your railroad without accidentally changing settings that might cause problems.   Works with any LocoNet compatible system   4-Digit addressing   Functions F0 - F12 for lighting and sound decoder operation   Direction switch with center brake position   ...

A TF4 can be used with any decoder that is not transponder equipped to add transponding capability to the loco.  It can also be used in any piece of rolling stock with track pick ups to add transponding.  For example, you could use a TF4 to add transponding and lighting effects to a caboose if it is equipped with track pickups to provide power and signal to the TF4.A TF4 should not be connected to an existing transponder equipped DCC decoder unless the DCC decoder's transponder is disabled. This avoids having 2 transponders responding to the same address in the ...

I am installing a DH165A0 in an Athearn SD70. The head light outputs are a nominal 30 ma (with the link cut). The bulbs were of course a bit lower in their current demands and were very bright for a short while. Is there any way to lower the current output from 30ma or do I need to add a resistor in line with the bulb to drop the voltage output? Of course if it is supposed to be a regulated current output this might be a problem. The DH165A0 has a constant current source for F0F and F0R, so ...

Prior to Disassembly Test the Decoder All Digitrax decoders are tested for proper operation before they leave the factory, but sometimes strange things happen. Therefore to insure your decoder is covered under our warranty policy, please give it a thorough test BEFORE you cut the wires. Test Run the Locomotive Be sure it runs correctly in both directions with no unusual noises or binding in the motor-gear train. If it checks out OK, then: Get Ready Before you start, get your tools and supplies together for this project. You will need the following items: DECODER TESTER - Such as the ...

Q:  Can I add a booster to my Zephyr? A:  Yes. Since the DCS51 Zephyr Xtra and DCS50 Zephyr are equipped with LocoNet, adding additional boosters is easy; you simply divide your railroad up into power districts and add the boosters and their individual power supplies. These are connected together using LocoNet cables. Because the Zephyr Xtra is rated at 3 amps and the Zephyr is rated at 2.5 amps: most boosters have higher ratings, you may want to have the Zephyr control a smaller area that has fewer power consumers (locomotives, lighted passenger cars), such as a main line ...

It is important to realize that the standard only covers the communication protocol on the track.  As long as it is not extended further than the basic track level communications for train control, creativity will be encouraged rather than stifled. This protocol is very basic and does not require any particular hardware. The Digitrax Complete Train Control System incorporates the DCC protocols for interoperability reasons but has not been held back by them.  Digitrax has developed and marketed automatic reversing boosters, decoders with 128 speed steps and user customizable speed tables, mobile decoders with onboard functions and lighting effects, stationary decoders with sophisticated ...

In service, the LT5 is plugged in to one of ...

Installation Notes: 1. Do not exceed the decoder’s 500mA total function output rating. 2. We recommend that the Blue wire, also called +Common or Lamp Common, be connected as shown. If you wish to omit the Blue wire in your installation, consult the Digitrax Decoder Manual for more information. 3. The head lamp should be hooked up using the Blue/+Common wire for optimal Digitrax transponding operation. 4. To use a function output with an inductive (coil) type load, see the Digitrax Decoder Manual for more information to avoid damage to the decoder. 5. See the Digitrax Decoder Manual for full ...

  There are two methods of providing power to the DS54: from the rails and from an auxiliary power source. The DS54 can be powered from the rails however, Digitrax strongly recommens that the DS54 be powered from an auxiliary power supply capable of delivering 12-16 volts (ac or dc) at 300 millamperes for best results.  Powering the DS54 from the rails reduces the current available to power locomotives and lighted rolling stock.  The auxiliary power supply connections are the red (+) and black (-) wires. Note: Digitrax recommends the PS14 Power Supply for independently powered DS54’s. Multiple DS54’s can be powered from a single power ...

I would like to use a Tomar Searchlight Signal such as model # 858. It has three color LED for each head. The SE8C manual shows the wiring example for bi-color LED signals. Is the SE8C able to control the three color LED signals as well? The bi-pole LED's can be used to produce a yellow "Approach" indication. The SE8C sends an AC signal to the LED, alternately lighting both the red and green sides to make a yellow (or "amber") Indication. Please see below: "A2" is connected to produce an approach (yellow) indication. You may find that the yellow ...

Testing the installed TF4 for correct transponder operation1. Place the unit with the installed TF4 on an empty transponding track section. This test assumes that the transponding track section is already set up, tested and is working before you start TF4 testing.2. Using a DCC throttle, select the TF4 address that was programmed into the TF4 and verify that the transponder detector identifies the presence of the transponder device. Depending on how you have set up your transponding reporting to the system, your system should detect the presence of the address in that transponding section.For example, if you have an ...

Installation Notes: 1. Do not exceed the decoder’s 500mA total function output rating. 2. If you plan to use functions F1 (traditionally a green wire) or F2 (traditionally violet), the return, also called +Common or Lamp Common, should be made via a wire carefully soldered to the Common (or blue) pin indicated as shown in Figure1. 3. To use a function output with an inductive (coil) type load, you must install a kick-back suppression diode across the connections. If controlling a coil type load, such as an electromechanical relay or motor, shutting the device off can cause an inductive kick-back ...

The UT4 comes InfraReady for layouts that are equipped with one or more UR90 infrared receivers. For Infrared operation:1. Install one or more UR90 infrared receivers on your layout.  These should be connected to LocoNet and powered.  If you have UR92s and/or UR91s present on the layout, these also support infrared operation.  You will need enough infrared receivers installed on the layout so that the throttles you use can "see" the receivers since the transmission is line of sight.  You may also encounter problems in rooms where there are large windows that would interfere with the transmission.2. Install a 9 ...

Most modern command stations and decoders are set up to run 28/128 speed steps.  If you are using older command stations or decoders you may need to adjust one or the other to get the trains to run.Why are more speed steps better?The reason you want to use a command station and decoders with 128 speed steps is for smoother speed control of your locomotives.   Digital command control signals are just that, digital.  When you send speed commands with your throttle, you are sending digital instructions telling the decoder to change from the current speed to a different speed.  When ...

1. The UP5 Universal Panel is designed for mounting on the fascia board of the layout. Cut a hole approximately 2.5” W x 1.5” H in the fascia board. Insert the UP5 through the hole with the face plate on the front of the fascia board. Attach the UP5 face plate to the fascia board with four #6 screws. Note: The UP5 uses the black screws to mount the front fascia plate.2. Connect the UP5 to LocoNet using pre-tested LocoNet cables. There are 2 LocoNet Jacks located at the back of the UP5 board for connecting LocoNet devices on your layout. ...

Photo Courtesy Kato, USA The DN143K2 replaced the earlier DN122K2 as a custom decoder designed for the Kato RDC in N-Scale. This is not a particularly easy installation and there have been some reports of problems with the headlights. Paul Lator has some experience with this installation, and this may be of help to you: "The wiring with the DN143K2 works well if you do not route the wires over the top of the seating in the RDC, rather completely disassemble the unit, mount the decoder in it's designated location then run the wires through the drive shaft tunnels. Place ...

When you are finished with your session, you should shut down the DCS50 by turning off power to the system.Shutting Down DCS50 Zephyr1. Bring all locomotives on the layout to a stop by setting set the Throttle Knob for each loco to STOP. 2. Turn track power off: Press the POWER key, the DCS50's Track Status Indicator Dot will go off. The display will briefly display "Po" followed by two characters, the Po means power off, the two characters indicate which software version is installed in the unit. The display will automatically revert to showing the last loco address selected ...

1. Carefully remove the locomotive's shell from the frame. Notice the orientation of the circuit board inside so that you can install the decoder in the same orientation. (Figure 1) 2. Remove the 10 black plastic plugs from the lightboard that secure the wires to the PCB. There are 4 plugs (retainers) on each end and 2 on the side for the motor connection. Remove the red and black wires, carefully noting where each wire originally connected to the PCB. Remove the lightboard itself by pinching the black plastic release tabs and pulling the board up and off of the ...

The Texas & Southwestern has a reversing loop, and DCC insures reliable and simple operation of trains in the reverse loop. This reverse loop is handled with a Digitrax AR1 Auto Reversing Controller. The automated features of the AR-1 make for seamless train movements, but an issue quickly arose. Because a reverse loop in a traditional DC-powered model railroad environment required manual operation, the track insulating gaps for the loop were usually located for the convenience of the operators. So the track gaps of the original track plan were situated to keep this inconvenience to a minimum. Note also all ...

My sound decoder has a capacitor, why do I need a PX112? The capacitor that came with your Digitrax sound decoder is designed to hold up sound operation in the presence of brief power interruptions.  It is not designed to keep the locomotive’s motor and lights running.  Our ears are very sensitive to sound interruptions so, the capacitor on your sound decoder will prevent most of these drop outs on average quality track.  Most people don’t even notice the small pauses in a locomotive’s movement and the small flashes of the lights when the track power is interrupted.  If you ...

What Digitrax decoders work in the new Athearn N scale FP45? We recommend the DN163K1C, following the procedure below. One of our editors was able to successfully install both the Digitrax DN163K1B and DN163K1C decoders in the unit. We have determined that the chassis design requires that the decoder be installed backwards. The only problem this poses is that one additional step has to be taken when programming. Both the DN163K1B and DN163K1C decoders are the same footprint with the exception of the LEDs. The DN163K1B has T-1 3mm LEDs and DN163K1C has surface mount LEDs. When the K1B version ...

Digitrax series7 mobile decoders have many industry standard Configuration Variable (CV) numbers and values, as well as numerous Digitrax custom CV numbers and definitions or controls. The series7 CV values are a superset of older Digitrax FX3 series3 and series6 decoders, already covered in Digitrax Decoder Manual V2 on the Digitrax Web site. The “CV8 to 8 default” columns indicate current factory defined value after writing a value of 8 to CV8, using; Service mode programming track or Mainline Operations Mode Write to the active decoder address. An entry with value/xx indicates a xx number invokes the value before the ...

Setting up your new Zephyr: Unpack the DCS-50 command station and the PS-315 power supply. On the back of the DCS-50,locate the gray screw terminal strip.On this strip, locate the two terminals labeled “RAIL A “and “RAIL B”.Attach these terminals to your track wires.It does not matter which is which. Before proceeding to the next step,make sure the throttle knob [1] is turned all the way to “stop” and the direction/brake lever [2] is set to”brake”. [See photo blelow]. Now, find the plug on the back of the DCS-50 marked “POWER IN, 15 VAC, 2.5 AMPS”. This is where you ...

I have an older Rivarossi Heisler that I have just installed a decoder in. I have 2 other Rivarossi engines, older, with decoders in them and they work. I use them as a template. Anyway, I can't get the Heisler to run. I have the orange wire at one side of the motor and the gray at the other. The red is soldered to the frame and the black is connected to the front screw where I disconnected the light etc. I just soldered the wires together. The motor is OUT of the frame so no short can happen. Can you ...

I have a Broadway Limited Import diesel locomotive equipped with factory DCC and Sound. Every time I turn on my Digitrax Zephyr DCS50 the engine starts to short out. It begins to slow down and then jerks a little and sometimes it stops completely. My Zephyr shows a line of flickering zeros across the dial and the engine decoder number even flickers on and off at times. I have checked all terminal connections and for foreign matter on the track but have not had any success in solving the problem.I have taken all cars off the track to make sure ...

Note: These instructions cover the hardwired installation of any Digitrax decoder with wires into a Kato GP35 H0 Diesel. Currently, the recommended decoder for current production GP35's from Kato are the DH163K0 board replacement decoder.  Using the board replacement decoders are much simpler and cleaner installation than the one described here.Tools Needed for Decoder InstallationYou'll need a few simple tools:1. A soldering iron, preferably temperature controlled.2. Solder3. Screwdriver4. Small diagonal cutters for cutting and stripping small wire5.

When the BDL168 is connected to LocoNet, it will communicate coded detection information to the system. If you wish to report BDL168 status to LocoNet and attached devices or computers that can interpret these messages, you will probably want to set up a unique board address for each BDL168. This is done so that the BDL168 Board ID does not conflict with the Board ID of other devices on the railroad. Board addresses can range from 01 to 999. It is recommended that you make a record of the addresses you use for all devices connected to your layout. Setting ...

I want to run a small 12V -16V AC motor via DCC and am not sure if you have a decoder for this and if so how to connect up.For Variable Speed:Some Digitrax decoders, such as the DG583S, can be programmed to operate AC motors. When you program CV61 to a value of 004, Digitrax decoders with split field motor drive capabilities will convert their motor leads to drive a "split field" AC motor instead of the default DC motor. This lets you run Maerklin 3-pole AC motors and similar motors in a number of locos built in Europe with ...

The prototype operation that gains the most from DCC is one of those least frequently modeled today: Rapid transit. Rapid transit consists of streetcars, interurban, subway, elevated or commuter rail track and equipment. The trains are usually very short and intervals between trains are relatively brief. Lots of trains run each hour and many trains are running at the same time. All of this operation is very much like a typical model railroad. Any photograph of a major downtown in the streetcar era will have from two to ten streetcars visible with some only feet apart. Simulating this type of ...

LNWI Security Considerations: Enabling and Customizing WPA2 Security The LNWI has the option of enabling WPA2 security to require a passcode to connect to the LNWI SSID.  The primary purpose of this passcode is to limit access to the LNWI in a public setting.  This is designed to operate in a similar function to the passcode options for Digitrax Duplex Radio. Using an unsecured connection poses minimal threat to LocoNet access as the LNWI only utilizes a limited number of LocoNet commands.  The LNWI does not have access to programming capabilities or other advanced LocoNet capabilities on your layout.  No ...

Direct Home Layout Wiring Digitrax strongly recommends direct home wiring where each power district and its booster are electrically isolated. This method of wiring has safety advantages and makes troubleshooting problems easier. In addition, direct home wiring makes detection work more prototypically. With direct home wiring, the BDL168 can determine and indicate whether any of its 4 zones is powered or not (possibly short-circuited) even when there is nothing on the rails in the detection sections. The BDL168 factory-set logic causes the detection sections to show "occupied" if the associated zone's power is off (because in this case, detection is ...

Do you have a reference for wiring Proto 2000 older geeps with a decoder (not necessarily sound)? We actually have several Life-Like Proto's sitting around for conversion to DCC, including an older GP-18, older FA's and such that date back to the days when DCC was just a twinkle in AJ's eyes. Overall, converting these locomotives will be fairly easy but there are a few things to watch for. Make sure that the decoder has enough capacity to match the current demands of the locomotive mechanism.  You must measure the stall current of the locomotive to determine this.   Make ...

"I had two Proto 1000 RDC's that I wanted to convert. After opening up the first one, I did what I usually do, yanked out all the circuit boards and such, threw them over my shoulder and commenced to hardwiring the decoder into the unit. Everything went fine, and I took it with me to a friend's railroad to enjoy what I had done. After I got there and played a bit, my friend commented that wasn't it neat that the Proto 1000 series has wiring connections on the circuit board in the locomotive, making things considerably easier. Wiring points?" ...
