Decoder Response Problem

Malcolm has a question for readers on Decoders and asks:

“I am testing a Lenz decoder and cannot access the address (decoder address number). I have a Digitrax Super Chief and am trying to change the address number. My answer on the control keeps on saying no pg. If I take the system out of programing and go to run I can get the decoder to respond to the forward command, but not reverse. If I can get an answer I will be grateful.”
