MELSEC A RS422 (25pin) <> iQR C24 Serial RS232 (9pin) - Simple PLC Communication
Communication from a MELSEC-A Series CPU (RS-422 – DB 25 Pin) with R Series CPU C24 Serial Module (RS-232 – DB 9 Pin).
I would like to request for support for the Wiring Diagram of the RS-232/RS-422 conversion cable. So far only Diatrend DAFXIH-CABV that works. But I couldnt find any wiring diagram for DAFXIH-CABV.
Due to high cost of DAFXIH-CABV, I am looking for alternatives, I am testing with standard RS422 <> RS232 converter in the market, but all failed to communicate, can anyone help?
