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 ...

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 ...

  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 ...

Q:  How do I reset the DS54 CV's to factory default values? A:  Each DS54 CV must be manually reconfigured to set the DS54 to factory default values. The factory default values for the DS54's CVs are: CV01 = 1 All other programmable CVs = 0

There are 1024 different CVs that have been defined to handle many characteristics you might want to use for your locomotives. Your decoder manual has a complete listing of CVs that are available in specific decoders, what they do and suggested values for each CV. 1. Place the decoder equipped locomotive you want to program on the programming track. If you are using operations mode programming, the loco you want to program can be anywhere on the layout but it must have a decoder that is capable of ops mode programming installed. 2. Enter Program Mode by pressing the PROG ...

The DS64 is a powerful stationary decoder that can be used to control different devices on your railroad. It can be used on both command control and analog model railroads. The DS64 is configured by the settings of different Option Switches (OpSw's), listed below: OpSw01 - Solenoid or slow motion devices OpSw02 - Pulse Timeout, 200ms OpSw03 - Pulse Timeout, 400ms OpSw04 - Pulse Timeout, 800ms OpSw05 - Pulse Timeout, 1600ms OpSw06 - Output Auto Power Up OpSw07 - Factory-default Reset OpSw08 - Regular/Extended Startup Delay OPSw09 - Timeout Option OpSw10 - Throttle/Computer Option OpSw12 - Sensor Input Option OpSw13 ...

The EDIT Key is used to enter the Edit Mode for editing the fast clock, routes, signaling, etc. It is also used to status edit decoders while in locomotive address selection mode.

In addition to the locomotive address, there are different Configuration Variables (CV's) that have been defined to handle many characteristics you might want to use for your locomotives. These include operational characteristics such as acceleration, headlight functions and others. The manual for each decoder type has a complete listing of CVs that are available in specific decoders, what they do and the suggested values for each CV. Simpler decoders have few CVs while advanced decoders may have many different CVs 1. Place the decoder equipped locomotive you want to program on the programming track If you are using operations mode ...

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 ...

This is a list of all configuration variables (CVs) and their factory default values in decimal and hexadecimal notation used by Digitrax mobile decoders.  Simpler decoders access only a few of these CVs, while advanced decoders access many, if not all, of these CVs.  

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 ...

Most Digitrax mobile decoders have a global reset function, which returns the decoder's CVs to their factory default settings.This is useful if the CV values in a particular decoder have been changed with less than wonderful results. For example, you may have accidentally set the CV value for acceleration so that the engine won't move for minutes when issued a speed command. This makes it look like the decoder is not working when all it needs is to have the CV value for acceleration reset. Many of the decoders that are sent to us for repair just need to have ...

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 ...

This procedure should be done on an electrically isolated programming track1. Be sure that only the locomotive you want to program is on the programming track.2. Press the PROG key on the DCS50 to enter programming mode. The DCS50 will display one of the programming modes available. Digitrax recommends the Paged Mode when you are using the programming track. If you press the PROG key repeatedly, you will cycle through the following choices:      PAGE     PHYS     dir     OPSFor example, to use Paged mode stop pressing the PROG key when the following screen appears:Each time you press the LOCO key the ...

Programming On The Mainline: Operations Mode ProgrammingOperations Mode Programming [Ops Mode] lets you program CVs in DCC locomotives equipped with Extended Packet Format decoders while they are on the mainline.  This is handy for situations where you want to make an adjustment to a specific locomotive while it is in service.  There are also situations where mobile decoders from other manufacturers can only be programmed in this manner. A typical use for Ops mode programming would be to change the acceleration rate (CV03) or the deceleration rate (CV04) of your locomotives to simulate the weight and braking capability of the ...

  To use the UT2 to program a decoder you must first put the UT2 in Programming Mode. To do this press and hold “RUN/STOP” and simultaneously press “PROG”. The Status LED will now turn a steady orange color indicating the UT2 is now in Programming Mode. Set the locomotive you wish to program on an isolated programming track (See Section 5.2). Make sure that the DB150 command station is not connected to any other part of the layout. If you don’t have a programming track on your layout remove any locomotive you don’t want programmed at this time. Decoders ...

What are the most common applications for the PR3? 1) Stand alone Sound FX programmer As a bench tool the PR3 is the first USB and second device designed by Digitrax for the programming of the SoundFX sound decoder. The PR3 does write to and read from the sound patterns of any SoundFX sound decoder. In addition the PR3 can write to and read from any CV of most current non sound mobile and function decoders found in today's market place. 2) Digitrax command station LocoNet to Computer interface As a layout control tool the PR3 is a second generation ...

CV29 is called the configuration register. It controls the following decoder characteristics: 1.  Whether the decoder uses 14 speed steps, 28/128 speed steps or loadable speed tables.  This affects how smoothly the loco will move and how it responds to throttle controls.2.  Whether the decoder automatically converts to analog mode when no DCC signal is present.  This allows the decoder to operate on a DC layout even though it is DCC equipped.3.  Defines the normal direction of travel for the locomotive. Normal Direction of Travel or NDOT can be changed when the motor connections of decoder have not been connected so that the locomotive runs ...

Digitrax Series 3 and later mobile decoders are reset by setting CV08 to a value of 08 to reset everything or 09 to reset every thing EXCEPT the loadable speed table.Earlier Digitrax decoders require resetting each CV individually. To reset earlier Digitrax mobile decoders: Reset your decoder to the factory settings by going into program mode and manually resetting the following CVs to these values: CV01=03 CV29=06 CV03=00 CV04=00 CV02=00 CV05=00 CV06=00 If you set up loadable speed tables, you may also need to reset CV65=00 CV66=00 CV67=00 CV68-93=00 CV91=00 CV95=00    

Some DCC systems need to have CV's 17 and 18 programmed separately to assign the decoder a 4 digit address.Digitrax command stations handle this automatically by default.  If you have a decoder that needs manual entry of CV17 & CV18, follow these steps:You cannot simply split the four digit address in 2 halves and input these into CVs 17 and 18. A conversion from decimal numbers to hexadecimal numbers is required. Once the hexadecimal conversion for the 4 digit address is performed, this number is then split in half and then each half is input into CV17 and CV18 respectively.To ...

How can I connect my PR3 programming output to an existing programming track on my layout that is already set up for programming and mainline operations? Install a non shorting multi position rotary switch between a isolated section of track, 4-6” longer than your longest engine, and the various desired outputs from command stations and the PR3 output terminals. The following schematic allows a single section of track to be fed by the rail output of a command station, the programming track output of a command station, and the programming output of a PR3. To add other third party decoder ...

Since 255 can't be divided evenly, the some of the numbers in the range 0 - 100% have been rounded.

As technology has advanced so have Digitrax throttles.  In the early days, it was not possible for the throttles to display decimal notation so hexadecimal was used.  The downside to hex notation is that you need to use a conversion table or a formula to determine the hex value to use for CV programming.  As better components and CPUs became available, we were able to move to the more user friendly decimal notation that you see in today's Digitrax throttles.  The move to decimal notation made DCC much easier to understand for everyone.  All current Digitrax throttles use only decimal notation for ...

When I turn the throttle knob, my locomotive quickly changes speed in large increments.A very common common problem is the throttle "jumping" 3 or more steps each time the throttle is turned.  This simply means the system is not set for 128 Speed Steps in that particular address.Earlier decoders, and some less expensive decoders, were set up for 28-speed steps or even 14-speed steps; very early command stations were only capable of handling 28 or 14 speed steps.  Technology has marched on, and most modern systems now operate using 128 Speed Steps.When first turned on, Digitrax systems are set to ...

The Digitrax DCS50 Zephyr is set at the factory to send 128 speed step commands to all mobile decoders.If you have a non-Digitrax decoder that can’t run in 128 speed step mode, you can change the number of speed steps the DCS50 sends to that decoder so that you will be able to control the decoder. This is called status editing the decoder. When you status edit a decoder, the DCS50 will send a different format to that specific decoder address without affecting the 128 speed step operation of Digitrax decoders and other 128 speed step decoders on the railroad.NOTE: ...

SoundLoader and PR3 have been tested to work on PC compatible computers running at 550MHz and up with Windows XP or Vista, 512MB of RAM. Other combinations of hardware and software such as Windows 98 may also work, but are not supported by Digitrax, and have not been tested to operate properly. Installation consists of three steps: Hardware installation, software installation, and software setup. Below is a photograph of the actual hardware connections required for SoundFX programming. Assemble the PR3 hardware as shown in the diagram below and connect to an appropriate power supply (Digitrax PS14 or equivalent). Note the ...

  Duplex Radio Throttle do not need to be plugged in to LocoNet to Program Decoders.  Simplex Radio & Infrared throttles must be plugged in to LocoNet to program CVs on the programming track.

Be sure that only the loco you want to program is on the programming track. If you are using operations mode programming, the loco you want to program can be anywhere on the layout but it must have a decoder that is ...

  Q: Can I assume that any of the 3 powering options for the DS64 are acceptable for OpSw changes? A:  Yes you can power the DS64 using any of the 3 options.  The DS64 is strictly looking for power, and doesn't need the DCC signal from the track to set op-switches. Q: If I have only 3 turnouts on a DS64, to complete the 4 point programming I have been inputting a bogus turnout number. Is that correct? A:  Yes, that is correct. Q: When setting OpSw 1, do I have to be connected to track power or can I power ...

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 ...

One special feature on the Texas & Southwestern is a built-in programming track. The programming track is located in a short section of track in the small engine terminal of the T&SW. This track has both rails insulated from the rest of the railroad. It uses a Double Pole Double Throw (DPDT) toggle switch to select what purpose this section of track is used for. When the toggle switch is set in one direction, the track has DCC power on it. When the toggle switch is aligned in the other direction, the track is now connected to the programming terminals ...

When you are programming decoders, there are a few error messages you may encounter.There are many causes for these error messages but most can be solved by checking the following:1. Be sure the programming track is connected properly to the DCS50.2. Be sure a decoder is correctly installed in the locomotive with all motor and pick up connections made correctly.3. Be sure the loco with decoder correctly installed is making electrical contact with the programming track and that it remains in contact with the programming track until programming is complete.  Check to see if the track is clean and the ...

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 ...

These are the basic DT400 and DT402 series throttle operating instructions designed to get you “up and running” quickly and to minimize your “frustration level” as you learn to use the throttle.   Turning Track Status On and Off To run your layout you must be sure track power and track status are both ON.  Follow these steps with your DT400 or DT402 series throttle to do this. Press the "PWR" key on the bottom left side of the throttle. The words “+ON  -OFF” will come on in the display. Press the “Y +” key quickly and you should see the ...

Status Editing - a DCC decoder's status can be manually changed by a Digitrax command station at any time the decoder is selectable. Speed steps are the increments of motor voltage that a locomotive's mobile decoder produces. Most DCC decoders can operate in 14, 28 or 128 speed steps. In some cases, older decoders operate only in 14 steps. You also may find that it is better to adjust the number of speed steps used by a particular decoder. Digitrax uses status editing to change how the command station communicates with an individual decoder. Our systems power up with the ...

Two Programming Methods Are Supported by Digitrax Command Stations:Service Mode Programming is done on an electrically isolated programming track. Using this mode, the command station broadcasts programming information to all decoders on the program track.  Within Service Mode programming are Paged, Direct and Physical Mode.Because these are a broadcast modes, we must isolate the decoder we want to program from the others on the layout by using a separate programming track that is connected to the command station for programming but not powered for operation of the locomotive. This mode works with all DCC decoders. This is the most commonly ...

On Page 9 of the instructions (under 5.0 Op Sw Set Up) I am to connect my DT400 throttle to my powered PM42 . . . 1. Does “powered” mean having the PS-14 power supply to the PM42 connected and energized? Yes. We took another look at the documentation and it means that the PM42 should be operating with its own power supply. What you are doing is using the DT400 to program the internal controls of the PM42; to do so would require that the PM42 be in its operating state, thus the power supply. The DT400 is merely ...

  Q:  How can I write and read the Configuration Variables of Mobile Decoder on the mainline using the DT40x Throttle? A:  Operations Mode Programming, also known as Ops Mode, lets you program a locomotive decoder's CVs while it is on the main line. With the addition of transponding in Ops Mode, you can write and read back CVs in DCC locomotives equipped with most modern decoders while they are on the mainline. Some older decoders before Extended Packet Format was used are not able to do this.For example: A typical use for Ops mode programming would be to adjust an engines ...

Operations mode (OPs mode) programming allows you to program decoders on the layout instead of having to move them to a separate programming track.  This is a write only programming method.  If you want to be able to read back the values written to a particular decoder using Ops Mode programming, you will need to install transponding on the layout.  If transponding is not active on the layout, you must use an isolated programming track for reading back CV values.The extent of the area with OPs Mode readback available depends on how muchof the layout is instrumented for transponding. The ...

There are two jumpers on the DS52 stationary decoder board. To properly use your DS52 you must be sure these jumpers are in the correct position. The configuration jumper sets whether your DS52 operates slow motion or solenoid type turnout machines. When the jumper is open it will run solenoid turnout machines. When it is closed it will operate slow motion turnout machines. The programming jumper determines whether the DS52 is in programming mode or not. To program the addresses for the DS52 the program jumper must be closed. For normal operation, it must be open. 

A  “Busy” message during programming means that the system is temporarily busy.  Simply try the task again.  When the system is no longer busy, you will get a “Good” response. A  “Fail” message during programming means that there is a problem with the locomotive on the programming track.  Check to be sure the loco's wheels are making good contact with the programming track.  Make sure that the decoder is properly installed in the locomotive.   Make sure the connections to the programming track are secure.  Make sure the programming track is powered. 

When using more than one DS64 in a DCC environment, you must assign a Board ID to each additional DS64 so that each one has a unique Board ID.You will need to set the DS64's board ID if you are planning to use the DS64's 8 inputs with a computer, system throttle, or other smart device on your layout that needs to know when a turnout has been manually thrown or closed via a particular DS64.You can use the 8 inputs on the DS64 to control the operation of the 4 outputs that control your turnouts.  For example, you can ...

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 you want to change the address or other settings of your locomotive decoders, you must set up a programming track. It is very important that the rest of your railroad can be isolated from the DB150 and the programming track when you are programming a locomotive. Decoders are programmed when the DB150 command station sends programming information to them through the rails. There are two basic ways of programming decoders. Service mode programming broadcasts a message to all DCC equipped locos that are on the track. Because this is a broadcast method, you will need to set up a ...

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 ...

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 Atlas DCC N-Scale locomotives that are equipped with factory installed Lenz062xf, Lenz063xf decoders will not program using any mode on Program track. I know the system works because I can easily program every Digitrax decoder loco that I have, but if I put an Atlas DCC factory loco on the programming track I get the 'd nd' error code.   There are decoders now present in the market that do not draw enough current for the programming track to reliably detect that they are present, hence the error report of "d-nd". All you have to do is to ...

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 ...

CV08 is the factory reset CV for all FX3 decoders and also the Manufacturer ID CV for all decoders. This procedure is performed on a programming track. To reset all CV values to their factory default, program CV08 to a value of 008/x08 while the locomotive is on the programming track. To reset all CV values except for 28 step speed tables to their factory values set CV08 to a value of 009/x09. Earlier Digitrax decoders must be reset manually, CV by CV. This procedure may or may not work with other manufacturer's decoders. When you "read" the value of ...
