In the Cerbo manual it says that various RS485 Modbus devices can be connected using a USB to RS485 adaptor. Does this mean all Modbus registers can be addressed by this method?
Would it be reasonable to infer from this that a USB-UART device such as those from FDTI could be used?
Yes
According to Internet reviews, the adapters work together with Victron.
YOU can read out all registers according to the ‘Modbus Register List’ and also write to the possible ones.
Excellent. I’ll give it a try.
