Greetings, I am trying to connect to a A-B PLC2 (1772 LN2 SERIES B) Using a Toshiba T1910 (running WIN 3.1 and dos 6.1) I am using a 1784 PMCK Series “A” card and going out through A 1784 PCM2 cable, hooking up to the front port on the PLC. It is not working, what am I missing. We had a tech come in with a powered cable , and everything worked fine. Same computer,same program( ICON AI ) ,the only (and probably the most important) was the cable Thanks for the help in advance
