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.

Configuración

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.

Use los siguientes ajustes Modbus en el asistente de dispositivo del EMS. Estos son los ajustes predeterminados para el medidor:

Baudrate: 9600
Dirección Modbus: 1 (o la dirección configurada en el medidor)
Paridad: Ninguna
Bits de parada: 1
Bits de datos: 8
