Hi All.

Wonder if some1 can help me. Im using a FX3G mitsubishi PLC and want to communicate via the RS422 coms port instead of adding a 232-BD adaptor. Is this posasble?

Thanks,
Nic

Hello,

Maybe.

IIRC Mac's had 422 ports and you could ground the + receive pin and if the other device responded to TTL voltage levels it would work. I could be wrong on the pin. Search the web and I am sure you will find the pin out.
