If the wiring shown in the table below is incorrect, please let us know.
There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.

You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
Use lower addresses first (1, 2, ...) because the SofarEMS will find them faster!
For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SofarEMS will scan on those first.
