Hi
I have a GE Fanuc Versa Micro UDR0005 PLC. This model has two rs232 and rs485 ports. I want to connect my nokia 6210 phone to it I have rs485->rs232 converter and nokia DLR-3 cable. When phone/plc is connected to the pc the communication via serial port works great but not when both connected with eachother. I know that I need a special cabel for that. Would be grateful if one of you could provide schematics for such cable.
Thank you
