H3-10.0-Smart Modbus help

Hi, anyone on here got this model Inverter? I've got the comms plug (rectangle, large thing) and connected to the only two pins that mention 485A/B to a RUNCCI YUN USB to RS485.
When I try adding to Home Assistant, I get the following error. I've tried switching cables but no go still. So guessing either the wrong pins connected to... anyone know for sure?

Error connecting to your adapter or inverter. Ensure the adapter is properly configured and is correctly wired to your inverter (see the setup link above), then try again.
