Two RV-C devices termination

I currently have a Lithionics battery BMS connected to the first CAN-bus port configured for RV-C with a VE Can RJ45 terminator in the second port. If I want to also add a SeeLevel 709 RVC do I simply remove the RJ45 terminator and use that port, or must I maintain a terminator? If so, how?

Thanks

RV-C is a multidrop parallel connection. Devices can be daisy chained. Both ends of the bus need to be terminated. Intermediate taps should not be terminated.

Nether the Lithionics BMS nor the SeeLevel 709 can be daisy chained because they each have only one port.

If the second Cerbo port requires a terminator, how can I include both the Lithionics and the SeeLevel?

Thanks.

Should be easy enough to build a bus with taps to the three devices, then a terminator on each end of the bus.


Look up RS-485 for ideas.
