I have recently bought 2 Digitrax TF4 decoders to control coach lights, I am unable to read or program these.? I have iTrain and a YD7001 and can read and program all my other decoders which are ZIMO.
I originally thought that I had a bad connection to the rails and so I connected them directly (one at a time) into the programming track output on the YD7001, still they cannot be read.
Any help would be much appreciated.
