It depends.
You need a GX device in the system for CAN connectivity, it can't connect direct to a multi.
It also needs to be a supported monitor:

Though third party devices may work fine, just unsupported.
Some BMS may require you to use an RSxxx connection, some local devs have produced a driver for the GX which enables this:
Again, support is between you and the battery/bms manufacturer.
Additional resources still need to be added for this topic
