I want to know how to connect serial cable from a SEL relays COM port to P34 2020 processor. I am using RS-232 to RS-485 Converter on SEL relay COM port but I am unable to understand how to connect RS 485 cable coming from RS-232 to RS-485 converter to P34 2020 port. In one article, I read that RS-485 cables are to be connected in RJ-45 connector on P34 2020. Can anyone confirm this?
