At first glance, the typical switching railroad would not seem to be a good candidate for DCC operations. Yes, there may be only one locomotive on many of these railroads, but that locomotive can still benefit from DCC. By adjusting the starting, mid-range and maximum speed values of this locomotive, you get very good slow speed control, perfect for the switching railroad. And, of course, if you add a second locomotive, then DCC becomes the clear choice because you are not longer having to throw toggle switches just to move around the yard. The DCC environment also gives you turnout ...

If you have trouble reading back CV's on the programming track, this may be due to insufficient current draw on the SFX064D function leads. You can always just re-program the CV value into a CV to get the desired results, even though reading CVs does not work. OPs mode is recommended for programming all CVs except CV01, CV17 & CV18 (2 digit and 4 digit addresses). If a second DCC decoder is present that is not Sound FX compatible then correct readback of CV data is not possible, since the NMRA CV readback was not designed for multiple decoder readback.

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 ...

KB940 Decimal and Hexadecimal Numbers

Over the years, different Digitrax throttles have used a combination of decimal, modified hexadecimal and hexadecimal numbers for entering CV numbers and CV values.  The following information is provided as a programming reference to show you how these different schemes work so that you will be able to use your throttle to program decoders.UT1 & UT2 Utility Throttles use decimal numbers exclusively for CV numbers and CV values.  Because these throttles use 2 selector switches that can access the numbers 0-9, you are limited to programming only CV#s and values from 00 to 99.DT100 Throttles use a modified hex numbering ...

KB419 How far apart to locate boosters

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. If your power district is a single track railroad stretching over hundreds of feet of linear distance, boosters should be placed at 50 ...

KB57 BDL168 - Connecting to a "Common Rail" Wired Layout

Common Rail Wiring Many older model railroads use Common Rail wiring because they were initially wired to operate with electrical toggle switches. Conversion to DCC is possible with Common Rail, but it is not recommended. Whole layout common rail is a method of wiring layouts where power districts and their boosters are electrically connected using a common rail or common power bus return wire. Whole layout common rail wiring is a disadvantage when it comes to detection systems since detectors cannot independently monitor whether zone power is on or off so they can't tell whether occupancy detection is working in ...

KB521 What is "Smooth" DC?

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 ...

KB621 Power Management Overview

Power Management is a concern on every layout.  With Digital Command Control, the main concern is that enough power is supplied to evey track section on the layout so that the digital signal is transmitted to the decoders in the locomotives and turnouts.Each locomotive uses power from the track, some for the motor, some for headlights and other functions and some for the command control electronics in each locomotive.  More electrical power is necessary to run more locomotives on the layout.  Digitrax boosters provide between 2.5 amps & 8.0 amps.  A small N Scale or HO Scale layout with two to ...

KB714 Loconet Overview

LocoNet is Digitrax's method of communication between LocoNet compatible devices on a model railroad layout.  LocoNet compatible devices are designed to work together on the network, and in some cases can also accept DCC commands from  the track, but often go beyond the scope of simple DCC train control.   LocoNet is a peer-to-peer Ethernet type multiple access network.  Because of its design architecture, it is very robust and powerful.  Layout implementation is simple and wiring is free form with minimal limits. LocoNet is designed to run an unshielded 6 conductor ribbon cable.  Digitrax recommends using flat, six-conductor telephone wire ...

KB902 Scaleable Speed Stabilization (Back EMF) in Digitrax Decoders

Speed stabilization is a feature that causes the decoder to run the locomotive at a somewhat constant speed according to the throttle setting. This means that if you set your throttle to 21% of total speed, the decoder will force the motor in the locomotive to maintain a constant speed at that level no matter what the track gradient or the load on the locomotive. The SD9 is an example of a US prototype that employed a load compensating type of control technology. Many modern European locomotive prototypes use some form of load compensation of the prime-mover in response to speed ...

SW01 to SW08 are inputs that allow a local switch mounted on the layout to operate the slow motion turnout machine. For example, SW01 when connected to the +VE sensor common (Pin 2 in figure) will reverse the voltages on SMTM1A and SMTM1B to change the position of turnout 1. SW02 controls local turnout 2 , etc. For each connection to +VE sensor common the slow motion turnout machine swaps direction and a Switch message is sent to LocoNet to report the new position of the turnout. This local control can be disconnected by setting OpSw 15 to closed, in ...

KB483 Bushby Bit - Disable Normal Switch Commands

Q: What's a "Bushby bit"? A: In your command station, OpSw27 can be toggled to disable normal switch commands, a.k.a. the "Bushby bit." This allows the layout operator to use an attached PC to handle switch control logic. Under normal conditions, advanced throttles can be used to operate turnouts which are controlled by LocoNet-connected stationary decoders. The factory default setting for OpSw27 is "t". Toggling OpSw27 to "c" takes this control away from the individual throttles and gives it to a controlling computer. Such an application would be a railroad with CTC control, where the train movements are directed by ...

KB287 CV54 Torque Compensation

CV54: Torque Compensation & Switching Speed In FX3 decoders, CV54 is used to control the decoder's torque compensation and switching speed features. Torque Compensation improves loco performance by internally adjusting for the loss of torque caused by SuperSonic™ operation. This feature is turned on at the factory. Switching speed gives you fast access to lower speeds used in switching operations. This feature effectively reduces the throttle's target speed by about 50% and reduces the effects of acceleration (CV03) and deceleration (CV04) programmed into the decoder by 1/4 when the user activates this mode by turning on F6.

KB405 UR91 Simplex Radio Receiver Frequently Asked Questions

Simplex Radio Coverage One UR91 should provide full coverage for a typical model railroad under most circumstances. Simplex Radio reception is affected by metal objects between the throttle and UR91 simplex receiver, or large metal objects adjacent to the receiver; a furnace is one example of such an object. Such objects cause a second reflected signal, impairing the radio throttle signal's ability to reach the UR91. In this case, the receiver gets the signal directly from the throttle, then another signal right on top of it from the reflection. Moving the UR91 to another location may solve this problem, or you ...

Security ElementsThe Digitrax Signaling System is organized around the concept of what we call "security elements", which are similar to what U.S. prototype railroads call "plants" or "interlockings". The Digitrax SE8C signal decoder displays aspects for up to 32 heads for 8 individual security elements (plants) using either a LocoNet Throttle or a computer with compatible software. When used with associated occupancy detectors and compatible software, the SE8C can be set up to protect the turnout with signals as shown by the example below. Note that trains can move from A to B, A to C, B to A or ...

KB403 Where to locate UR90, UR91 & UR92 for best performance

With LocoNet, you can use Infrared, Duplex Radio and Simplex radio individually or in any combination on your layout.You'll need to be able to observe whether your command station is receiving commands from the UR panels when you are installing infrared or radio receivers and transceivers.  Your Digitrax command station makes it easy to determine when the system is receiving a signal and when it is not.  You can observe the NET LED and the Track Status Indicator or your ...

KB308 PM42 - Local Annunciation

How can I remotely monitor the input and output status of a section of the PM42 that is configured to act as a circuit breaker at a remote location? The final output stage, of each section, of the PM4 or PM42 is a DPDT relay. The contacts of this relay act in a similar fashion as the contacts of a DPDT toggle switch. These inputs and outputs can be monitored in a variety of ways. Three common monitoring devices are a LED (with appropriate resistor), a lamp (of the appropriate voltage), or an optical coupler (with appropriate resistor). The following ...

KB379 Super Empire Builder Power Requirements

The answer to this question applies to all Empire Builder sets including Super Empire Builder XtraQ:  I have just purchased a Super Empire Builder set. My expectations are for it to operate an N-Scale switching layout right now with future expansion to a larger N-Scale layout. I am a little confused as to which power supply I would need at this time. I am reading about power supplies and inline fuses, all of which is a little overwhelming to me as I am getting back into the hobby. Can you recommend which power supply will be better for me as ...

KB871 Keller SU1990 Sound Unit with Digitrax Decoders

You can easily control sound units like the Keller SU1990 by using the function leads on Digitrax Decoders and DCC command station that can control decoder functions. These instructions for connecting a Keller Engineering Diesel Sound unit to Digitrax DH83FX & DH140 series decoders was writtne many years ago.  Any modern Digitrax decoder with 4 function leads can be used. Equipment Needed:1) A Digitrax Throttle, Booster/Command Station or other DCC command station capable of controlling decoder function outputs.2) Any Digitrax decoder with at least 4 function leads will work here.3) The locomotive you wish to convert, be sure to check the ...

KB183 Speed Tables

A speed table is a list of numbers, one number for each speed step. Many operators customize their locomotives by adjusting the CV's for Vstart (02), Vmid (06) and Vmax (05) to set the throttle response characteristics for each locomotive. This is known as a three-step speed table It is also possible to create a more complex speed table, either with 14 or 28 steps that specify the exact percentage of full power sent to the motor when the throttle is set to that speed. Speed tables can be set up for 14 or 28 speed steps, but not for ...

KB456 DT402 & DT400 - Fast Clock Operation

Many operators use a fast clock during operating sessions to simulate prototypical operations. Traditionally, the fast clock is on the wall in view of the train operators; it is set up to run at a faster than real time so that an operating session can simulate prototypical operation on a compressed time scale. LocoNet has its own networked fast clock for all Digitrax throttles connected to your system. The fast clock display is a 4 digit 12 or 24 Hour format clock. To display the fast clock simply press the CLOC c Key. The fast clock display will remain active while ...

KB207 Case Study: Texas & Southwestern Part 3 of 11 - The Railroad

Based upon a layout designed by the late, great John Armstrong which appears in the classic book, 101 Trackplans for Model Railroads [Kalmbach Publishing, 400-12012, still in print], this railroad combines different elements to offer varied model railroad operations. At the center right of the railroad is the Union Passenger Station. From this station, trains can operate out & back, which is to say that a passenger train leaves the station, goes out onto the circular main line and eventually comes back into the station after passing through the reverse loop. Another passenger train can operate point to point, meaning ...

KB472 Layout Blocks - A Small Example

Train detection and the related signaling can be a complicated affair. However, it becomes easier if you analyze things and break them down into their component blocks. The whole idea is to protect trains from each other, regulating their movements by the use of signals which tell train crews what to do or what to expect. Train detection identifies which segments of track are occupied by a train. For the real railroads, track detection sections can be very short (such as at track junctions) or very long (such as in rural environments). Train speed and frequency of trains are also ...

KB91 Powder River Signaling Example

I am now constructing an N-Scale layout with Digitrax DCC system. I know SE8C and two-heads signal mast supplied by your company are applicable for a entry signal mast for the both of main and siding (branch) lines. However, I don't know how the signal mast is used in the case of "more than two" siding lines. For example, the next picture was taken in Powder River Basin (Converse Jct.) in Wyoming State. TS, Japan In this picture, some two-heads signal (mast) can be seen. In every signal mast, the top signal head will be for a main line. But, ...

KB129 Recommendation For Small Starter Layout

I have a 4x8 H0 scale layout.  I'm 13 years old and REALLY thinking about switching to DCC, I need to know really fast because I want to ask my parents to get it for Christmas.You wouldn't know by looking at those who edit the Tech Support Depot, but there actually was a time when we too were thirteen, and just starting out in model railroading.  In many ways, we still are thirteen years old; we just can't move as fast.  Consider this photograph from our youth: This little bit of ancient model railroad history dates back to the 1950's, ...

KB943 Functions on Mobile Decoders

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 ...
