InfoRS485 Wiring
- For correct RS485 wiring: follow the RS485 wiring guidelines.
- If the wiring shown in the table below is incorrect, please let us know.
- There is no general industry consensus on the use of A and B for RS485 polarity, so the naming may be counterintuitive for some devices.
WarningNOTE: 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.
Check the device manual on how to enter the energy meter's configuration menu.
