Unable tro read CV - Atlas Gold Series

[cncproadwarrior]

I'm attempting to program my Atlas Gold GP50 on the program track with my NCE ProCab but it gives me an "Can not read CV" every time. I reset the decoder but still no luck. It runs fine but I would like to set some of my other locos to the same settings.

I'm pretty sure you can't do a readback on them, though you should be able to get a verbal confirmation of any settings if you program in ops mode.

Finally found something. If the decoder and sound decoder draw too much power on the programming track, it will cause this display.
