  1. questionAmerican Wire Gauge
    American Wire Gauge (AWG) is a U.S. standard set of wire conductor sizes. The "gauge" is related to the diameter of the wire. The higher the gauge number, the smaller the diameter and the thinner the wire. Typical model railroad copper bus wiring is AWG number 12 or 14. Connecting wire is often ...

  2. questionRecommended Tools for Decoder Installation
    You'll need a few simple tools when you begin installing decoders: A soldering iron, preferably temperature controlled. Though many installations do not require soldering, you may still need to use a soldering iron to install extras like lamps for special lighting effects. Solder. A small scr ...

  3. questionSoldering Basics
    Basic tools for soldering: a soldering iron, solder, wire cutters, wire strippers, tweezers, heat sinks, etc. This photo does not show an example of desoldering braid which is useful for touch ups and removing mistakes. If you are building a model railroad, you will need to learn to solder. T ...

  4. questionBrass Locomotives
    I have several old brass locos and they have Pittman motors. I have tried DH163 Decoders and blown two. I believe that they draw excess current that exceeds 1.5amp cont. Is there an HO mobile decoder with the same size physically as DH series, but has higher current ratings? Suggestions? While i ...

  5. questionBachmann K4
    I have a Bachmann Spectrum K-4 4-6-2 steam locomotive #84114 and would like to add sound. Bachmann is no help. Today I bought a Digitrax DCS50 controller and a DH165 series decoder at my local model train store and asked about a sound decoder. He was no help either. What sound decoder will work ...

  6. questionMarklin Z-Scale
    I have an extensive collection of older (15-20 years) Z-Scale Maerklin equipment. Can I convert the locos to Digitrax, or must I buy some other brand of loco to use Digitrax? Maybe yes, maybe no. It depends upon the size of the locomotive. We are aware of several European Z-Scale model railroads ...

  7. questionAvoiding Heat Problems With Decoder Installations
    Most HO, N & Z Scale model locomotive motors and lamps are designed by the locomotive manufacturers to operate at full speed at 12 volts DC on the track. Digitrax recommends running your DCC command station and boosters at the lowest track voltage possible that provides acceptable operation. ...

  8. questionAthearn Genesis SD70-Adding A Decoder and Setting Up Ditch Lights
    Athearn Genesis SD70s came factory equipped with a Digitrax designed light board. The board is NOT a DCC decoder. If you want to add a decoder and have alternating ditch lights the following steps are recommended: 1 - Remove locomotive shell; 2 - Remove dummy nine pin plug from wire harness and ...

  9. questionAthearn N-Scale P59PHI Installation Instructions
    The Athearn N-Scale P59PHI was not designed for a plug 'n play or board replacement installation therefore, a wired installation will be necessary. This installation is straightforward if you follow the instructions provided below. There is plenty of room inside the locomotive for this installat ...

  10. question9 Steps For Successful Decoder Installation
    1. Read the instructions FIRST and PLAN your installation. Have the proper tools on hand. 2. Choose a locomotive that runs well on regular DC. 3. Choose the appropriate decoder for your installation. 4. Test the decoder before installation. 5. Carefully disassemble the loco. 6. Isolate the motor ...

  11. questionMotor Isolation Protection FX & FX3 Decoders
    FX3 decoders have motor isolation protection. If the decoder senses that the motor is not isolated, it will not run the motor. In this case, you will be able to control the loco’s functions but the motor will not work. FX decoders will blink the loco's lights when power is first applied to ...

  12. questionSome Thoughts on Decoder Installations
    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 change ...

  13. questionDH165A0 - Function Outputs
    The DH165A0 is set up at the factory to control six function outputs. The DH165A0 is configured to control the forward-headlight F0F/white lead and reverse-headlight F0R/yellow lead for directional lighting. These two headlight function leads are current regulated for LEDs or lamps, with facto ...

  14. questionSFX0416 - Wiring Connections
    Wired Mobile Decoder with SoundFX™+Accessory type functions for most HO scale Locomotives.

  15. questionSFX004 Installation Instructions
    1) Identify the correct orientation and mounting side and of the DH165 series decoder to plug this sound module into. There is text saying "SFX here" etc,. The SFX004 must only be mounted from the correct side and orientation, for each of the DH165 host decoders. 2) With correct orientation ...

  16. questionElectrical Paths in older locomotives
    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. Th ...

  17. questionChoosing a Locomotive for Conversion to DCC
    Choose a locomotive that runs well on conventional DC power. Digital decoders cannot compensate for faulty motor operation, poor track pickup, etc. If you are not happy with the way your locomotive runs on regular DC power, installing a decoder will not make it run any better. If there are any m ...

  18. questionDZ125 - Installation Instructions
    1. Carefully remove the locomotive’s shell from the frame. Notice the orientation of the shell to the frame so that you can reinstall correctly. 2. The DZ125 has 6” wires that you will solder directly to the appropriate connections inside the locomotive. The smaller size allows th ...

  19. questionDZ125IN - Wiring Diagram
    Note: The connections illustrated above are for purposes of illustration. The NEM socket has six conductors which are arranged in numerical order from 1 - 6: Contact 1 - Motor Connection (orange wire) Contact 2 - Motor Connection (gray wire) Contact 3 - Track Pickup (red wire) Contact 4 - ...

  20. questionDZ125 - Installation Notes
    Installation Notes: 1. Do not exceed the decoder’s 500mA total function output rating. 2. We recommend that the Blue wire, also called +Common or Lamp Common, be connected as shown. If you wish to omit the Blue wire in your installation, consult the Digitrax Decoder Manual for more infor ...
