Check the Pro380 terminal labels Follow the manufacturer wiring diagram for the exact Pro380 revision. Connect RS485 A/+ to controller A, RS485 B/- to controller B, and the communication reference to GND when available. Verify the labels on the installed meter before energising the bus.

Configuration

NOTE: RS485 Device Addresses

You MUST give each device a unique address on the RS485 bus. Check the device manual for instructions.
Use lower addresses first (1, 2, ...) because the Sofar EMS will find them faster!
For each device, it is generally recommended to keep the factory-default baud rate, parity, and stop bits. The Sofar EMS will scan those first.
