I'm having some issues communicating with this PV 1200. I have my regular PV cable and a 25/9 pin adapter as well as two other serial cables with 25 pin serial / 9 pin serial connections. I've tried all three with and without my null modem adapter and cannot get any communication in RSLinx DF1 nor the PV1400 transfer utility, which is supposed to work for the 1200. Serial port settings match the config in the PV. I am on the assumption that the serial port on the PV actually works, but it may not. PV in config mode / download-upload screen.
