RS485 Wiring
- For correct RS485 wiring: Follow the guidelines for RS485 wiring.
- 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.

Avviso
NOTE: RS485 Device Addresses
- 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 Sofar EMS will find them faster!
- For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The Sofar EMS will scan on those first.
Di default, l'inverter è impostato sull'indirizzo 1. Questo può essere modificato tramite il display dell'inverter. La procedura si trova nel capitolo 7.3.2 del manuale.
