Q:  What is the white wire for on the SoundBug? A:  The white wire is used on conjunction with a driver cam for steam sound synchronization. Q: What type/size loco does "generic" steam sound represent? A:  This sound was based on recordings of Union Pacific 3985, a 4-6-6-4 "Challenger" type.  Q:  Does the Sound bug come with an oval speaker to fit in the shell of the older model GPs or SDs that do not have space in the fuel tank. A:  The SoundBug comes with a 28mm round speaker but others may be substituted. The included-speaker is rated at ...

I have a DH165AO decoder and Sound Bug and am installing the decoders into an Athearn SD70 Locomotive.The motor controller works and the sound as well. However, I am unable to get the lights to work. I connected the wire leads exactly as they where on the Athearn light board. Athearn uses twin forward and rear 1.5 volt lights yet the DH165AO will not power the bulbs. It will power one bulb at either end but not two. The single bulb setup glows very brightly but for a short time. So I tried using the 47 ohm resistor in parallel ...

If the sound does not start when you run the locomotive with a sound decoder installed try the follwoing:1. Make sure you have selected the locomotive on a throttle. The sound will not run unless the locomotive is addressed in the system.2.  Make sure the sound is not muted.  Try toggling F8 which is the Digitrax standard function for muting the sound decoder.3.  Made sure the volume in your decoder has not been turned down to a very low level.4. Check your installation to make sure the decoder is installed properly.

The sound in your decoder shuts down after you stop it and you are not using a Digitrax system for control. On some DCC systems decoders are not addressed by DCC packets after the locomotive is set to 0 speed. In this case after the CV11 timeout elapses (6 second factory default setting for SoundFX decoders), sound will shut down. To remove the timeout and prevent sound shutdown, set CV11=00.  This would leave the sound in the locomotive on until you remove power from the loco.Digitrax command stations continue to refresh locomotives by periodically sending packets to them as long ...

Can the SoundBug sound like a juice jack, i.e. a GG1? Yes. The SoundBug, like all Digitrax Sound FX decoders, can be set up with any available sound project. Any recorded sounds can be set up as a sound project file (.spj) which relates the sounds to individual actions of the locomotive. Many project files are available on the Digitrax Sound Depot and on the web.  Sound projects are free. 

1) Connect the Red and Black track wires from the 9 pin Track and Function harness to the locomotive track power connections.2) Connect the function leads that are to be used from the 9pin Track and Function harness. Note that to be able to readback Sound FX CV's a combination of function lead loads of at least 60mA at 12volts should be connected to these function leads. Insulate the unused function leads so they cannot short to the locomotive frame or track power.3) Mount the 28mm speaker attached to the 10pin sound feature harness in an appropriate sound enclosure. Be ...

If the sound output from your SoundFX decoder is distorted, try the following:1. Check the speaker cone for magnetic debris that may have collected there. Debris on the speaker will cause a loss of sound quality and must be removed.  This is a common problem in speaker installed facing down toward the track.  Remember, speakers are magnetic and will vacuum up magnetic debris along the track.2. Be sure that the CV58 volume is not set at a level that is too high for the speaker. For impedances below 32ohms (e.g. 8 to 30 ohms) set the volume setting lower to ...

To get the most out of your SoundFX decoders you'll need an internet connection in order to get to the Sound Depot website (digitrax.com/sounddepot). For the casual user, access to the Sound Depot site will let you download new Project files that other users have customized. So if you want to change your loco's factory default GP38-2 sound project, and another user has previously uploaded a GP38-2 sound project file with something special, perhaps a different horn configuration, you can do it. It's easy: Just go to the Sound Depot and download the desired new sound project file or use ...

Is there a way to automatically decrease the sound on my sound equipped locomotives when they go into a tunnel? No, but you can use F8 to mute the sound when you enter the tunnel and F8 again to turn it back on when you exit the tunnel.Some clubs have "no chuffing" zones, where many trains are present at the same time. Operators who do not know about F8 are quickly apprised by others when they enter a busy yard.   F8 Mute (CV135) may be changed to a non-zero value, such as CV135=16 to lower the sound volume.  This ...

The sound performance of any speaker is greatly affected by where and how the speaker is mounted and whether an adequate speaker enclosure or baffle is installed.The baffle is used to isolate to speaker diaphragm's front side sound waves from the out of phase rear sound waves. This minimizes sound cancellation, particularly at lower frequencies. For most efficient sound generation, the volume of the baffle should be as large as practically possible. The baffle walls should be acoustically rigid to prevent acoustic interference.Practical materials to use for the baffle are plastic, cardboard and sheetmetal. Common items such as cardboard tubes ...

Fred Miller has been an invaluable resource for information about Digitrax sound. Here are some of his thoughts about the sound project files, from the Yahoo Digitrax Sound discussion group: There seems to be confusion over what is a SPJ.  Yahoo closed down all Groups in 2019.  The information is still relevant.   Fred Miller has also written a program called SPJHelper which easily lets you create/modifiy Sound Projects. There are additional Sound Projects on Groups.io - Look for AnPRR owned by John McMasters.  He creates many SPJ Sound Projects.   It is not surprising since it is a very ...

I have loaded a new scheme but the CVs and Functions are not working as I expected. Load the sound project you programmed into Sound Loader.Select the "view>project description" from the menu.The text file that describes how the project you have loaded will appear on the screen.Read the text file to be sure the sound project is suitable for your needs.If not, load a different sound project and see if it works better for your application.  

Many Digitrax SoundFX decoders come with two different sound schemes pre-installed.  Check the decoder instruction sheet for which sound schemes are installed in the decoder you are using.  Instruction sheets are available on this website on the product pages for each decoder.The decoders come from the factory with CV60 programmed to a value of 01 to play the default scheme.  If you want to play the other pre-installed sound scheme, simply program CV60 to a value of 00.  You can switch back and forth between the two schemes.  Changing CV60 does not erase either pre-installed schemes.If you want to download ...

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 ...

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 ...

I don't understand what the white cam lead gets hooked up to. Some model steam locomotives are equipped with, or can be equipped with, a cam arrangement which coordinates the sound to the rotation of the drivers creating chuffing. As the wheels turn, a switch opens and closes, operating the chuff sound produced by the sound decoder. The white wire goes from the decoder to a microswitch which is operated by a cam that is mounted on the axle of one of the drivers. In operation, when the white wire senses the DCC track signal, it operates the chuff sound ...

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. I tried to program an SFX0416 with my PR2 and the sounds did not "Take". I clicked the big green "Program" button and after the initial buzzing for about 15 seconds, nothing further happened and now the unit makes no sounds. I am using a Compaq XP-home 1.5GHz laptop with SoundLoader version 1.16. How can I fix this? A. The most likely issue is that you are using the earlier SoundLoader version 1.16, which was not configured for full support of 16M bit flash sound memories, such as those used in the recently released SFX0416. SoundLoader was updated in ...

When using Soundtrax Sierra Sound with Digitrax LArge Scale decoders, go to the Soundtrax website and download their SoundTraxx Technical Bulletin #7.  Technical bulletin available at www.soundtraxx.com   Soundtrax is your source for information using their Sierra Sound with Digitrax decoders.

With Digitrax Sound Definition Language, you can use .wav files to create custom sound project files. The process of converting 'raw' sounds recorded in the field into a sound project file takes time and patience to produce a finished sound project file that sounds realistic. Tips for Recording Locomotives and other Sounds Recording the sounds is a major part of creating great sound projects.  You need good recordings to work with.  Record several complete sound events (several complete whistle blows from start to finish, etc.). This will give you several recordings to choose from when editing to produce your sound ...

These are the Function buttons for sound control:

Editor's Note: This tech note has nothing to do with Digitrax SoundFX sound decoders. This is for users who have Digitrax command stations / boosters / etc and wish to program MRC sound decoders. --------------------------- Due to low programming track power in certain dcc systems, programming sound decoders on the program track may not be possible, especially trying to assign the decoder a four, (4), digit address. This programming procedure has to be performed on the mainline, where more power is available for programming sound decoders. If your dcc system allows simple 4 digit address programming on the main, [ops mode ...

I have a DCS50  Zephyr system.  I'm having a great deal of problems with it when I try to run (2) loco's equipped with LOK SOUND and DCC decoders (by ESU).  What happens is that it cuts in and out 3 to 5 times on each revolution of the train. I see it cutting out on turnouts sometimes, but not on straight track.  And sometimes when the loco's are on a hard pull, like at a sharp uphill curve.  When they cut out it just isn't the loco's, but the entire railroad.With the addition of the sound electronics, power consumption ...

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

UT4 Function Control Keys and How they WorkThere are 8 physical keys used to control functions F0-F12 on the UT4 throttle. F1 through F6 and F7-F12 share the same keys.  You will see F1-F6 in black print and F7-F12 in blue print to remind you that you will need to use the SHIFT key to access F7-F12. To use functions F7-F12 you must press and hold down the SHIFT key on the lower left row of the throttle as you press the F7 through F12 keys to activate any functions available on those functions. All the UT4 functions work like other Digitrax throttles. ...

OPS Mode Programming Soundtraxx Tsunami Sound Decoders      This article was originally written for Soundtraxx Tsunami decoders.  It will also work for other manufacturer's sound decoders.   The individual CVs that make up an address will need to be programmed individually.

Digitrax SoundFX lets you make your locos sound like the real thing!Remember, your Digitrax SoundFX decoder is ready to run and will operate and generate sound using address 03 with no additional programming.On your Digitrax system, simply select the locomotive's address and the sound will start. On some DCC systems, it is necessary to select the locomotive address AND send a command to start the sounds. When used in conjunction with a separate DCC motor decoder in a single locomotive it is most practical to program both decoders to the same address and operating modes.For a more prototypical railroading experience, ...

My son & I have PROTO 1000 Diesel EMD F3A-B Sets. The powered locos are equipped with an eight-pin plug for easy decoder installation. Our problem is that we've been looking through books & have no idea what sound card & speakers we are going to need that corresponds with these type of locomotives. I was told that they would need sound cards that are from the "Early Diesel" era. If this is true, please tell me what sound cards,speakers & wires do we need to make this happen? We are fond of F-units, and the Proto 1000 F-units are ...

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 ...

Apply gentle and firm pressure behind the SFX004 connector to engage the pins until ...

  Q:  I have read in some of the model magazines that the F2 button on the DT400 is a pressure sensitive playable whistle button. I have not noticed any difference in sound with the F2 button on my DT400. Is there some way to determine if this feature is present on my throttle? A:  Most Digitrax DT400 and all DT402 series throttles have the capability of implementing the playable whistle feature when used with Digitrax sound decoders.Prior to the release of Digitrax sound decoders this feature was considered as an experimental throttle feature and was not fully documented. Once Digitrax released ...

Speaker Mounting and baffle/enclosures. The sound performance of any attached speaker(s) is greatly affected by the mounting system and required baffle or rear enclosure. The baffle is used to isolate to speaker diaphragm front sound waves from the out of phase rear sound waves. This minimizes sound cancellation, particularly at lower frequencies. For most efficient sound generation, the volume of the baffle should be as large as practically possible, and the baffle walls should be acoustically rigid so not to allow acoustic interference. Practical baffle materials are plastic, cardboard and even sheet metal. Common items such as cardboard tubes or ...

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 ...

Is it possible to add a pair of PM42 Power Management Modules between the command station Rail A/Rail B outputs and run the resulting output from the PM42's on as many as 8 sets of Rail A/Rail B Wires to 8 isolated power Zones? These isolated power zones could have their Common Zone (Rail A) Wires running through RX1 transponding receivers connected to an RX4 ribbon cable running to the BDL168 for the purpose of interfacing with the SurroundTraxx Multi-Train Sound System. If this is possible, it would only require 5-6 of the DS lines on the BDL168 to be ...

CV133 and CV134 work together to control chuff timing. CV133 and CV134 can be adjusted to create the desired chuff rate in your locomotive, or you can configure your sound decoder with CV133 and CV134 to use an external cam to create chuffing sounds. CV133 Steam Chuff/CAM configurations: CV 133 set to a value between 1-127 determines the driver size in inches. (Default Value = 63) CV134 Steam gear ratio trim CV 134 set to a value of 32=100% ratio. Setting CV133's value from 1-127, puts the sound decoder into 'Autochuff' mode. Autochuff mode tells the decoder to simulate driver ...

The sound project loaded into this decoder can be operated independently of any other DCC motor or function decoder. If another non-Sound FX compatible DCC decoder is connected to the track leads then CV readback of SFX064D Sound CV's and PR2/PR3 SoundTest modes may not be possible. Note that it is always possible to Write CV values using Operations mode or a Service Mode programming track, even if CV Read is inoperative.If the connected function loads are insufficient for CV readback or an incompatible DCC decoder is also connected, it is still possible to download a complete sound project by ...

I would like to re-power two old Athearn Alco PAs and sandwich a dummy PB in between. I would like to know if is possible /practical to install a sound module in the dummy unit. Actually, there's probably enough room to fit something in the A-units, but you could install sound into the B-unit if there is a way for track power to reach the sound unit. Consider the SoundBug SFX006 which replaces the SFX004): The speaker diameter is 28mm, or just a bit larger than an inch. You will need to fit the speaker into a baffle and the ...

Transponding gives you operations mode readback of decoder CVs while they are on the layout (for decoders with this feature). Your dispatcher will know where trains and other equipment are located. Feedback from your transponding decoders lets you know the zone location and address of any piece of transponding rolling stock on the layout. This information can be presented on a display panel, your computer or even on your throttle. Feedback from the locomotive decoder also can provide information about the speed and other status data for the specific locomotive. With transponding, you can FIND the location of a specific ...

How do I get all the engines of a consist to run at the same speed? I have 3 engines with DH163A0 decoders and one with a MRC sound decoder. All units have the same top speed, but the unit with the MRC decoder starts and accelerates more quickly. Getting a group of locomotives to operate at the same speed can be a challenge. Experience has proven that it is best to work with the slowest locomotive and bring the other locomotives into agreement with that engine. Since the others appear to be in general agreement, it would be the ...

Most intermittent operation faults on all layouts, not only DCC ones, are caused by bad electrical connections and poor wheel pickups on locomotives.  Poor electrical contact causes problems with sound decoder operation in particular.  Sound decoder installations usually include a capacitor to store energy to keep the sound going when the decoder briefly loses electrical contact.   When the track is dirty or corroded, it can't transmit the electricity and DCC signal needed to run locomotives.  When the locomotive pick ups are dirty or corroded, they can't pick up the signal from the track.  Check your track cleanliness and quality of wheel pickups ...

The master volume control CV is CV58, its values range from 0 to 15.  The factory default value for this is 09.Digitrax SFX decoders have a factory default value of 09 set for CV58.  This works well for 32 ohm speakers.The decoder will reset to this value whenever you do a decoder reset of CV8=8. Digitrax SFX decoders built for use with 8 ohm speakers should have this value changed to 4 or 5 for best operation value of 4 or 5, since the decoder may not supply enough current at high volume/drive levels.Your results may also depend upon track voltage present. Kato USA says ...

What are the different operational modes available in the PR3? The PR3 is the combination of two previous Digitrax devices: the PR2 decoder programmer and the MS100 LocoNet to computer interface. The PR3 can be configured through manual (control panel buttons) or automatically (software) means to perform any one of the following three operations: a) The PR3 can be configured to function as a stand alone decoder programmer. In this mode the PR3 can program the configuration variables of most DCC decoders and the sound effects of the Digitrax Sound FX sound decoders. b) The PR3 can be configured to ...

Proven technology for bi-directional layout control without the need for modifications to your existing DCC system investment.

Digitrax SoundFX decoders will automatically operate on smooth DC power unless analog mode conversion has been disabled. The sound will not start until approximately 5 volts is applied to the track.  Due to this characteristic of analog operation with a DCC decoder installed, the start up sound will not play.

Performing factory decoder reset using Digitrax Zephyr Xtra (DCS51) or Zephyr (DCS50)Overview:To reset a Digitrax decoder 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.Procedure:1.

SDN144K0A installation question about the capacitorIs the 100microF capacitor needed? Or is it only for use in the Kato E8B unit when both LEDs are removed? If it is part of the installation, what size hole doesit need for mounting? The 100uF capacitor is required for all installations.  The capacitor provides keep alive voltage to the decoder.  This is important when the locomotive runs over a section of dirty track or is traveling through a non powered (insul-frog) turnout.  On non-sound equipped locomotives, typically you will not see the locomotive hesitate or lose power when it encounters dirty track.  With ...

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. The addition of these functions can add to the fun and realism of your locomotives.You must have ...

When purchasing a loco that says its decoder ready, exactly what is implied? Does this mean wires can be wired into the numbered locations and nothing else is needed except to remove jumpers?As with any technology, it takes time for standardized terminology to become established.  Although DCC is almost twenty years old, there are still some gray areas with descriptions.  It really depends upon the individual manufacturer, and within one manufacturer's product line there can be variances also.  There are several types of locomotive decoder installations and you may find that these terms are not applied by all manufacturers in ...

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 ...

The LGB MTS (Multi-Train System) is DCC based, so a system such as Digitrax Super Chief 8 Amp and a high current power supply such as the Digitrax PS2012 (rated at 20 amps) will work successfully.However, the LGB system is not a pure DCC system and there are reports of problems when Digitrax units are used to program LGB decoders, especially the sound decoders.  The latest LGB MTS decoders (Generation III) will operate with NMRA DCC systems, however some of the sounds and other functions may not work.  Some users have reported creating a "hybrid" system, but we do not recommend that ...

  Could you please explain what the notch rate does- is there a range for this? Is there somewhere with more detailed explanations of the various CV's- such what what the air drier or compressor rate might be? Diesel locomotives are operated by "notches", which are the rate at which the locomotive's diesel power is being applied. Traditionally, these are called "Run 1" to "Run 8". At Run 1, the locomotive generator becomes active but the locomotive prime mover (the diesel engine) does not increase in speed. With Run 2 to Run 8, the locomotive's engine speed (and thus the ...

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 ...

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.

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, ...

Overview: Broadway Limited has issued a new line of H0-Scale locomotives called "Blueline". These locomotives are equipped with sound decoders that can be operated in a conventional Direct Current environment. They also are fitted with an 8-pin DCC Medium plug to allow for conversion to a DCC operating environment. Among other decoders, Broadway Limited recommends using our DN143IP mobile decoder for this purpose. Converting these locomotives is simple, but programming a 4 digit address can be a challenge. BLI has a support page which indicates that changing the locomotive address and other CV's can be done in OPS Mode (also ...

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 ...

  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 ...

I have Diesels with Atlas sound or decoder, Bachmann EZ command and Soundtraxx decoders. Will the DCC Super Chief work with these decoders? Yes. Because the Atlas, Bachmann and Soundtraxx decoders are DCC compatible, they will work with any Digitrax system. There may be a issues related to programming with these decoders that require special attention. Please consult the decoder instructions for the particular locomotive to determine if any special steps are necessary in your particular situation.

Q: I have 2 Broadway non-sound F7 DC locos. I bought 2 DH163IP decoders for them. However the decoder is too large to fit into the 8 pin plug provided on the PC board in the loco. A: We recommend a DZ146PS for those locomotives. They will fit in the space available. Don't be confused by the Z designation of this decoder, it is rated at a full 1 amp to run most HO locos but it is small enough to fit in Z scale locos.

Our website offers a Decoder Selector Tool that can be used to find recommendations for locomotives made by different manufacturers by scale and model number.May factors will influence which decoder you choose to use for any given locomotive.1.  The physical size of the locomotive and how much space is available for the installation.2.  The current draw of the motor. 3.  How many functions do you want on the decoder?4. Is there a board replacement decoder available?5. Is there a plug for the decoder built into the loco?6. Do you want a sound decoder?7.  Other decoder features that might be important to you.

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.

If the Zephyr DCS50 repeatedly shuts down briefly and then comes back on again, it is probably being run too close to its pre-set current limit of 2.5 Amps or it may be overheating due to restricted air flow to the bottom of the unit. In this case it may clip or mutilate some outgoing packets of information to keep the track current within acceptable limits.To solve this problem, reduce the track current load by running fewer locomotives or setting up additional power districts and adding more boosters to provide more power for the layout.  With more sound decoder equipped ...

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.

Q: I'm using the SDH104K1B+FN04K1 in a custom installation. The supplied speaker is a bit too large, and I'm having difficulty sourcing appropriate-size 32 Ohm speakers. I can, however, find 4 Ohm and 8 Ohm speakers that fit my needs. A: No, you should use 32 Ohm speakers with decoders that specify 32 Ohm speakers for the best performance. Check with your dealer to find 32 Ohm speakers that are available from Digitrax. If you decide to use 8 ohm or 16 ohm speakers with the SDH104K1B, you will need to adjust the speaker volume downward to reduce distortion that ...

Q:  I have three engines lashed together. The sound is coming through . However when I turn the knob there is no response. The engine in the window is blinking and there are two stationary dots above A:  If you are using a DT300 series or DT400 series throttle, make sure that the Track Status Indicator dot in the upper right of the display just below the right throttle knob is on solid.  If it is not on at all Track Power is OFF.  If it is blinking, Track Status is in Idle and the throttle knobls will not move the locos.  To ...

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   ...

The Intermountain 2014 release of their F-Units require some special attention when installing a decoder.  There are three locations which require attention to make sure the motor and headlight LED are completely isolated.  If the motor is not insulated, you'll hear a buzzing sound when the locomotive is placed on your layout.  I would suggest trying to program the locomotive on an isolated service mode programming track.  If you're successful in programming, the motor is properly isolated. 1. The motor has to be removed from its mount and Kapton tape needs to be placed from the bottom of the motor ...

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 ...

DT400 Series Throttles - Make F2 Latching or Non-latching The F2 button on the DT400 is meant to control locomotive whistles and horns, so it is configured to be "momentary" or non-latching.  This means that the key will activate the horn or other function for as long as you hold the key down and stop when it is released. This was done to facilitate the use of a playable whistle in sound decoders. If you are not using F2 for this purpose on your layout, you can change the way the F2 key on the throttle works so that it latches on and ...

Zephyr Xtra (DCS51) and Zephyr (DCS50) systems can program Soundtraxx Tsunami decoders using Blast Mode Programming on the Mainline.  Blast Mode Programming will program EVERYTHING sitting on the main line track so, you MUST remove everything from the track that you are not programming or use an isolated piece of track connected to Rail A & B. NOTE: Track power must be ON during Blast Mode Programming.  Blast Mode programming will work with all sound decoders not just Tsunami. You will not be able to read back CVs using Blast Mode Programming.  To use Blast Mode Programming with Zephyr, close ...

The Mode Switch: The Mode Switch next to the Green LED is used to toggle back and forth between MS-100 mode and PR2 Programmer Mode. The Green LED will wink once per second if in the MS-100 Mode or toggle every second when in the PR2 sound programming mode. The Loconet Termination Switch: The switch next to the error LED is used only in MS-100 mode to activate the Loconet current source termination feature. This switch is active ONLY when a command station is NOT connected to the Loconet and the red LED is solid on indicating there is no ...

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 ...

When I hook up my USB cable to my PC the DCS240’s blue USB led turns on, but Digitrax DigiIPL II, LocoMon and SoundLoader II utilities do nothing when opened. What is the problem? The blue USB led lit on the DCS240 means that the complex USB Enumeration and startup sequence has successfully completed.  Be sure to select the correct COM port number that is now associated with this DCS240 in the software you are trying to use.  You can see this COM number appear in the “Ports (COM & LPT)” entries of e.g. the Device Manager function of Windows, ...

By Zana & A.J. IrelandThis clinic is titled Digital Command Control: The Wave of the Future. Recently, I was asked the question: "DCC has arrived and is the technology of today, everybody's using it so, why don't you change the title of your clinic?" My answer is that digital command control is still evolving rapidly. Today's digital command control is moving beyond the basic NMRA DCC Standards and RPs to encompass many new technologies that will compliment and enhance the basic things we can do with the track format defined by the NMRA. It's an exciting time for model railroaders ...

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 ...

Digitrax uses CV33-CV46 to handle remapping according to published standards.The CV values that are permitted for function remapping are limited to 8 bits, a maximum value of 255. Therefore only 8 functions can be mapped to each function key.Function remapping is easy! Just follow these simple steps:1. Locate the row for the Throttle Function Key [chart below] that you want to use.2. Locate the column of the Function Lead Color (number) you want to control.3. Note the value at the intersection of the row and column.4. Program that value into the the CV listed next to the Throttle Function Key. ...

  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 ...

Stall Current is the max current draw in amps for a motor when it is stalled. This is important in determining which decoder to install in a locomotive. Why is Stall Current important? In the conversion of analog locomotives to DCC, how much current the locomotive draws is a major factor in decoder selection. Decoders are grouped by their ability to handle the electrical load that flows through them to the locomotive motor. The Ampere (Amp) is the unit of measure for electrical current used by the locomotive. The current draw of most HO can motors is between .5 and 1.5 ...

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 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 ...

The following CV settings have been found to give great performance from the Trix Mikado. These settings were discovered by Norm Stenzel after much trial and error.  Once the loco was set with the following CV values this locomotive operated very nicely with the sound synchronized to its movement.

  My layout is in N scale, with an 85 foot double track main, a 12 track storage area, small yard, and engine facility. The layout measures 10 X 14 with two helices. There are a total of 34 engines, many of which are with their trains in the storage area. All of the already made-up trains (11) have two or three engines on them, ready to be brought up via a helix to run on the railroad. Currently, the road is divided into six parallel blocks (DC); 12 blocks in all. In the future, I plan on adding a ...

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 ...

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 ...

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 ...

'It is possible to operate one conventional DC locomotive at Address 00.  In many cases, this is the first locomotive that beginners use when they first get their command control system.  In other cases, this locomotive is one which cannot be easily converted to DCC.  Regardless, although it is possible to use your Digitrax system in this way, it is not a recommended approach.1. Place an analog locomotive (one without a decoder) on your layout.  While the analog loco is sitting still, you will hear the characteristic “singing” caused by the DCC track signal when it is applied to analog ...

Note: The programming shortcut for 4-digit addressing outlined in the Digitrax Zephyr manual will not work to program the Tower 55 decoder in any programming mode on the Zeyphr throttle due to a programming timing issue with the DSC50. Please use the procedure referenced in this bulletin to access this feature.Note: If the DCS50 or DCS51 is being used as a command station with a DT400/DT400R throttle connected via the Loconet ports, then the programming shortcut for 4-digit addressing outlined in the DT400/DT400R throttle manual will work to enable the 4-digit address capability of the decoder when using the DT400/DT400R throttle ...

This article was originally posted on this site in 2006, but the source material dates back much further than that, probably back to the early 1990's, when DCC was an emerging control system. The article discusses non-sound mobile decoder programming operations. Many of the issues discussed in this article are less relevant when using recently produced decoders, but this text still does cover some questions which may be raised when you are using mobile decoders which were manufactured by other companies. These decoders will operate in the Digitrax environment, but you may need to make some adjustments.The earliest Digitrax mobile ...

The front panel of the DB150 Super Empire Builder has electrical connection points, indicator lamps, LocoNet connections and toggle switches which give status indications, configure and connect the unit for your railroad. Power Input The two “POWER IN” terminals on all Digitrax boosters & command stations are the power input connections. Please see the related articles about power requirements for the DB150. Power Supply Digitrax recommends the PS515 power supply to power the DB150. There are many other transformers and power packs that can supply the input power for the DB150. Check with your Digitrax dealer for suggestions. Most regular ...

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 ...

This H0-scale railroad track plan first appeared in the Atlas Model Railroad Company's book "Six Railroads You Can Build", written by John Armstrong and illustrated by Tad Stepek. This book was first published in 1958 and has been reprinted several times. A classic bowl of spaghetti, the Transbay Interwoven has two reversing loops and a turntable. DC Control For DC operation, Atlas specified three Atlas Controllers (for the reverse loops and the turntable), two Atlas Selectors (to control eight track segments) and ten controllers for the railroad's turnouts. DCC Makes Things Simple With DCC, the wiring of this railroad is ...

DCS240 FAQ   I’m getting a “StealZap” or message on my DT402 rev 2 throttle. What is this? This is a feature that helps prevent having the same address selected on multiple throttles and creating unexpected operations.  When you steal you are truly stealing control of the locomotive instead of sharing it as was the case before the DCS240 and DT402 R2 firmware were released. When using a DT402 R2 throttle with an Advanced Command Station featuring expanded slots, each throttle ID is associated with the Loco Addresses it has selected.  When you select a Loco that is selected on ...

There was a time when every mobile decoder installation was a custom installation. In those early days, we were just feeling our way along, trying to find ways to make the existing supply of decoders fit into locomotives which had been designed in a different era. Fortunately, things have changed along the way, and in many cases, the Digitrax Decoder Selection Guide will list your locomotive. But many locomotives are not listed because they are too new or are too generic for a special listing. So, from time to time, you will have to "wing it" just a bit to ...

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 ...

I am putting the finishing touches on my 10 x 20 foot H0 railroad. It is a copy of the Cajon Pass, Salt Lake & Santa Fe RR by John Armstrong (#86 in the 101 Track Plans by Linn Westcott) [Kalmbach Publishing, ISBN 0-89024-512-6; still in print]. I have decided to go with DCC and my local hobby store recommended Digitrax. The layout is in my basement, I will be the only operator, the plan has 54 track switches (34 NJ International twin coils and 20 Tortoise turnout motors). Can you give me an idea as to what equipment I ...
