Reading generator status/information via RS485 to Cerbo GX

I have an Kohler 12Kw dieselgenerator, with Modbus/RS485 connection. Anyonoe setup readout of statusvalues from the generator, so its visible in the Cerbo dashboard? It can be useful to remotly read different information from the generator. I have a full modbus description for the generator. But i’m still not able to communicate via my USB to modbus between the generator and my cerbo gx.
