PM861 COM3 port pin details for RS232 communication.
I am using COM3 port of PM861 controller for RS232 modbus communication. I have a RS485 to RS 232 converter whose RS232 RJ45 pin details i am sharing here.
Can anybody help me with the pin details of COM3 RJ45 port. Also which pins are to be connected to the coresponding pins of the RS485 to RS232 Converter.
Thanks in advance.
