PM861 COM3 port pin details for RS232 communication.
Hello All,
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.

Hi,
as per attachement, you can use, ABB Standard TK853 cable pin configuration. But TK853 comes with RJ45 on one side and D9 connector on another side.
Your RS232/RS485 converter is having RJ45 port instead of D9 or connection pins/terminals. So i believe straight RJ45 cable would work!! else you can crimp as per TK853 configuration.
You can refer below link for more details.
