Hi Babs , like yourself I was unaware of this feature which is not available on all ESU decoders until a recent purchase of a Lokpilot 5 Micro decoder and stumbled on an ESU USA video which unfortunately only describes the process using a Lokprogrammer and an Ecos which is as simple as toast , i'm all Lenz but do have a sprog which works well with Decoder Pro but not so in this instance , I don't think the problem lies with ESU or the decoder itself but is most likely with my configuration of DP .I inherited the layout a year ago and knew next to nothing about my late fathers plans for it other than it had Traincontroller Gold installed on it's dedicated PC , I had no knowledge of DCC or computer control other than what my dad said in passing when I visited him so it's been an almost mind numbing year for me trying to get to grips with an almost complete system that I had no idea how to finish .If anyone has used DP to accomplish this task I would be most grateful for your input .
