I am using a NCE 5 amp power pro with the Soundtraxx booster on the program track.  I have had nothing but problems trying to program the shay which has DCC and sound.  Have tried POM, program track but nothing.  Does anyone have a step by step procedure they use to program or am I looking at changing the decoder, etc?   

Just purchased unlettered Shay with sound and power decoders, is there a step by step procedure to programming on programming track or mainline using the NCE 5 amp power pro.  Right now, I get "cannot read" when trying to recognize decoder manufacturer and version.  Am still familiarizing myself with DCC system.
