KB537 DN142 - Turning on Back EMF

The DN142 comes from the factory with BACK EMF SPEED STABILIZATION (BEMF) turned off. Follow this procedure to turn it on and to adjust it. Later generations of Digitrax mobile decoders do not require this procedure. Activation: To activate the BEMF feature, change CV57 to a value of 06. This will give good performance with most brands of locomotives. If the locomotive surges while using BEMF use a lower value for CV56. It may also be necessary to adjust CV's 55, 56, & 57 to get the motor performance desired for your particular locomotive. Adjustment: 1. Program CV57 (Droop control) ...

KB888 Installation of Digitrax Decoders in HO Scale Atlas RS1, RS3, RSD4/5

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.

If you use the DN140 the installation will require fewer engine modifications because of the smaller physical size of the decoder.Note any decoder of smaller physical size can be used in this installation.  DN135D, DN163, DZ123, DZ125, DZ143 are all possibilities. After removing the shell from the locomotive chassis, note the color and location of each of the various wires.  All connections must be soldered with rosin core solder and insulated with shrink tubing.We will locate the decoder in the forward ...
