KB559: Lenz & Atlas decoders show d-nd

Q:  My Atlas DCC N-Scale locomotives that are equipped with factory installed Lenz062xf, Lenz063xf or 'new' Atlas decoders will not program using the DCS50 in any mode, either on the OPS track or 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 presnt in the market that do not draw enough current for the programming track to reliably detect that they are present, hence the error repot of "d-nd".

All you have to do is to use a 1K ohm 1/4 watt resitor across the Prog A and PRg B outputs during the program process and it will program the Lenz/Atlas decoders.
