I'm having a nightmare trying to get lookout to talk to a Mitsubishi FX-24MR
PLC (just the one), using a Mitsubishi FX-485ADP comms module, and the FX-485PC-IF
rs485-rs232 converter. The SD and RD lights on the PC side of things are
flashing, but only the RD light on the PLC module is flashing - the PLC just
doesn't seem to want to send any data. I've tried this using 2 and 4 pair
wires. Anyone have any ideas? Think it might be related to D8129, but I'm
not sure.
