Kevin, We use a 25 Pin RS232 F-F from the KFC to the TCA. I think KFC requires a null modem and a KF-2 doesn't, but I will verify that in the lab on Monday. I have both running, so I should be able to get this right. (Maybe I'll win the car!) . Also we have had issues with certain versions of the firmware on the KFC. I'll check with our PLC gurus and let you know which version of the firmware definitely works.
