i am having trouble communicating with an old varitrac ccp2 system. the cable i use works with old stat systems and comfortrac systems in hyperterminal and also with the tracker software for newer tracker and varitrac. is there a special cable for this one only? It has been a long time and I had a trane cable before . i made the one i use now. if so what is the pinout for it? I thought it was a standard rj-12 with a generic serial adapter.
thanks for any input.
