Title: Trouble programming my Bachmann Loco with a Digitrax control system
Post by: Yardmaster on March 04, 2012, 04:44:09 PM
The following is from the Digitrax website:

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 use a 1K 0hm 1/4 watt resistor across Prog A and Prog B outputs during the program process and it will program the Lenz/Atlas decoders. Some of the new Digitrax decoders also require this same approach.

"d nd" is the error code for decoder not detected. This problem can also arise if the locomotive has dirty wheels or the programming track is dirty, with the dirt interfering with current flow.
