Growatt 6000T - RJ45 to RS485 pinout - Help

Anyone know the pinout of the Rj45 - Rs485 port seen below, need to convert it to usbA TO HOOK TO Raspberry pI 4B, thanks in advance Joe.
I believe the RS485 can be used to read the inverter, as long as your manual describes it as a parallel or expansion port instead of the BMS port. It should probably work with PV Keeper and/or SolarAssistant.

Gottch, Solar assistant will do 10 second updates and has 18 sensors to feed my Home Assistant via Mqtt, Just bought 4th pi4b 8g and loaded Bullseye but haven't loaded anything on it. Not a coder so SA was the easiest way to go for me, have hardwired 2 - jdb bms's and 4 gyl batteries, Gyll's are reporting to SA/HA and am working on getting Jbd's into Home Assistant. MotionEye on pi0 shows up in HA as video of my main battery monitor and all is viewable via the cloud or local ip.
