Same, I need the DCC mumbo jumbo in broad strokes, I said BROAD STROKES, but once the mumblers start mumbling, it's all Orks and Ballrogs, no idea what they do be saying.
I think that the basic premise is that anybody who wants to run two different DCC locos on the same track, using ESU decoders, will HAVE to change the address for one or the other.
In the case of the IRM DBSO, you need it to have the same address as the loco, so happy days.
