Hey guys,

I recently got one of the new 44 ton switchers, the one that comes with factory installed DCC. I took it out onto the layout to test it on factory settings and it seemed to run well enough. However, when I tried to program the CV's, my Prodigy Express system could not change any CVs. I tried on the programming track, in ops mode, and using the 1k ohm resistor trick I read about. Nothing works. Does anyone have some insight on changing the factory installed decoder's CV values?
