I could not find a wiring diagram for the Moeller EASY-PC-CAB cable (serial cable to connect EASY control relay to a PC computer). It is the same cable as the Eaton EASY-PC-CAB, but apparently the pin-function diagram is a company secret. Too bad.
The cables might be the same but I saw two different part numbers on the Allied Electric website. One is for the 500/700 series, the other is for the 800 series. I also searched to find a wiring diagram with no luck, the same as Lancie1.
