Good Day all;

I have the above set up, and just recently, like yesterday, tried for
the first time to program a digitrax TF-4 function only decoder.
What a dismal failure, sigh.

I've never had a problem with this set up before, done Tsunami,
Loksound, Soundtraxx, and Digitrax motor control decoders, all with
no problem.

Don't know if it's a sprog or decoderpro problem. I tried direct to
decoder connections, and various resistor ideas trying to simulate a
motor load, etc. Decoderpro reports an error "stopping due to no
locomotive detected". It's pretty adamant about it. It's not the
decoder, I was able to program one on a digitrax programming track.
Did Digitrax design a decoder that only works on their system in
spite of what the instructions say? Am I doing something stupid??
Any ideas would be appreciated.

Cheers
