Next I will have to learn how to program decoders and set up
rosters.?
You might start with and related help found through the links found there. As you progress, through that adventure and get to understand specific questions, this resource is always open. Lots of other people on this list know more than I do about Loco decoders and rosters.
One question, I have several Intermountion HO ET44AC's that use ESU
Loksound decoders, and I don't see that decoder choice in the decoder
list....are these decoders compatible with decoder pro?
The best way to find out is to open a new "Topic" with a specific question.
If you can identify the decoder model using the DecoderPro, put "ESU Loksound" and the model info in the subject line.
If you cann't, then put the locomotive identification in the subject line.
Either way should trigger the attention of the ESU specialists on this list and I am not one of them.
