RS-485 Communication Connection
There are two RS-485 ports available for communications between the UXIM and remote controllers
(BMS) or accessory modules (not currently supported). Each of these ports is labeled 1 and 2. When
connecting to a remote controller, connect the A & B connection of port 1 to the remote controller.
When multiple units are used together and need to be connected to a remote controller, these modules
can be networked together using the RS-485 (1) terminals A & B. See the figure below.
