How to connect ABB relay REM543 for configuration

How to connect ABB relay REM543 for configuration

(OP)
I would like to ask the way to connect ABB relay for configuraiton. I've tried with CAP505 and front connection port with optical link (1MK9500001-2) but the software show the problem with communication so I'm not sure the possibility for this problem.
details: ABB REM543 CG212AAAA ,sw version 1MRS-110022-001 rev B, the software CAP505 has two avaiable options for REM543-1MRS118502 revC and REM543R-1MRS118520 revC. So I have a question that is there any issue with software version compatibility as above or not.

I've set on the front connection of the relay for SPA address=1, baud 9600 with serial interface and CAP505 communicaiton attribute: baud 9600, data 7 bit, even parity, 1 stop bit. But the communication can't be successfully connected. (or I should go to comm port on backside of relay --> if so please suggest?)

Should anyone has any suggestion on how to connect this relay will be very appreciated.

"data 7 bit,"

seems odd. Most I've seen are 8 bit (serial comm). Just a guess.
