Product Support for: Mobile Decoders -> 1 Amp, Wired Mobile Decoder, 2 Functions, Back EMF (DZ125)

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

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

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

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 that use Digitrax. We also know of a very large Z-Scale railroad in Washington, DC that uses Digitrax. This particular railroad is a model of Swiss prototype, so the locomotives are all electric-types; there seems to be enough room inside for a decoder, especially the new DZ125 series ...

How to add DCC to the new run of Bachmann DCC ready Dash 8-40CW? The current recommendation is for direct soldering, using either DZ125, which controls headlights only or DZ143, which controls headlight and two additional functions. With earlier units, either milling of the frame or a replacement frame was necessary, but the new units have a "DCC ready frame"; the source of this information also points out that Bachmann is using the same model number for both the older version and the newer version, so you should make certain that you have the recent version.

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 ...

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

Many thanks to Bob Dattore for this application note!This app note details using a DN142 decoder for the installation.  This decoder is no longer in production but the following decoders would work as well:  DN135D, DN163, DZ123, DZ125, DZ143.  Any decoder that is small enough to fit could be used.The Problem:  Atlas RS1's (and RS3's & RSD4/5's) are hard to install Digitrax decoders in. There is no easy drop-in or light board replacement with back-emf capability.I have installed several Atlas Dual Mode decoders in these popular hard to fit narrow, low hood diesels with ease, by replacing the original light ...
