Greetings,
I have a REC Q BMS on a 48V system, connected to one of the BMS-Can Port. The other is terminated. There is nothing on the Can-bus connections.
In the The Settings --> Services --> BMS-Can Port it shows up on Can-bus BMS (500 kbit/s), however under network Status it shows an error: State ERROR ACTIVE (TEC: N/A, REC: N/A).See image. I have nothing connected to the non-BMS Can-bus inputs.
