Use lower addresses first (1, 2, ...) because the SofarEMS will find them faster!
For each device, it is generally recommended to keep the factory-default baud rate, parity, and stop bits. The SofarEMS will scan those first.

By default, the meter is set to address 1. This can be changed via the meter display.
