Coomunication with FR-A500

[elenercom 1]

Hi everybody, I have RS232/RS485 converter of DELTA , which has R+ and R- terminals for RS485. I want to communicate my laptop with Mitsubishi Inverter FR-A500. The PU connector of inverter (RJ45) has 4 terminal SDA, RDA, SDB and RDB. My questions are: 1. Can I communicate with inverter with that conveter? 2. If it's possible, how should I connect ? Thank you for your reply.

Mitsubishi already sells a cable to do this. SC-FRPC. I would use that one personally.
