Atlas HO Locomotives

Application Note: Walthers/Life-Like F7 H0-Scale steps needed for the DH163D DH123D decoder installation. Remove packing protectors screwed to coupler pockets: Carefully remove shell by spreading sides at side windows: Here's an alternate method for removing the loco shell - our F7 unit had a particularly stubborn shell. In place of the X-acto knives pictured, we recommend toothpicks or something a little safer.. Remove DC Plug (or a DC Printed Circuit Board in this case) from the wiring harness: DC Plug shown removed: Plug DH123D or DH163D decoder to 9 pin wire harness and mount it as shown: Reinstall loco shell.

Steps needed for the DZ125PS or DZ143PS decoder installation: Remove couplers and carefully remove loco shell to reveal the 8 pin dummy (DC) plug. Remove 8 pin dummy (DC) plug [picture shown with plug removed]. Plug in the DZ125PS or DZ143PS with orange wired #1 pin in pin with triangle marked pin. Detail of DZ125PS or DZ143PS with orange wired #1 pin correctly oriented. Tuck decoder in cab area of loco, replace shell and reinstall couplers.

  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 application note concerns the DA120 deocder, which began production in 1997 and was discontinued around 2000. The DA120 decoder that is being shipped with the Atlas locomotives has certain variables that are available for programming. These guidelines are provided for those who are using the Wangrow or Lenz systems for programming the DA120 decoders.The following variables were selected by Atlas to be offered in the DA120. These CV's are available to be programmed on the DA120:    * CV01 - Address    * CV02 - Start Voltage    * CV03 - Acceleration Rate    * CV04 - Deceleration Rate    * CV05 - Maximum ...

These instructions detail the installation of a wired Digitrax decoder (a DN140 in this example, but many wired decoders may be used) into an Atlas GP35 manufactured by Kato prior to September, 2007.  These units are marked "Japan" on the bottom of the locomotive.  Units marked "China" use a board replacement decodr such as the DN163A2.Installation DiagramNotes:A. Be sure motor leads (Gray & Orange) do not touch frames & have protective insulation in place.B. Be sure frame is straight & mechanism is correctly reassembled & can turn freely without binding.Wired Decoder Installation InstructionsFollow these steps for decoder installation with either ...

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 ...

The DH165Q1 fits many Atlas, Intermountain, Life-Like & Other factory sound equipped HO locomotives. Installation Instructions - Intermountain F7 example: Removing Locomotive Shell and Disconnecting Lightboard 1. Carefully remove the front coupler and then the locomotive's shell from the frame. Note the orientation for proper reinstallation. 2. Unplug and mark the two track power pickup 2-pin plugs, the motor 2-pin plug and the 6-pin headlight plug(Figure 1) Observe and carefully note the original wire locations! One of the track power plugs and the 2 pin motor plug can be inadvertently swapped when hooking up the new decoder PCB. 3. Unscrew ...
