I'm new to DCC and believe I just destroyed my Digitrax DH163 decoder by trying to program it while I was running the loco. Is this a major "no-no" with DCC? It had been doing fine until I decided to be a little adventurous by changing the acceleration and decel rates while I was running the loco. About 5 minutes into this, the locomotive stopped and all I can see now is the rear light on when I power on. I seem to still be able to read my CVs and tried resetting the decoder multiple times with no results. Nothing seemed warm to touch, but I can't think of any other explanation. Please advise. Thank you!
