Cableado RS485 de la serie Autarco LD | Sofar EMS Documentation

Esta página describe la comunicación con un inversor híbrido serie LD de Autarco mediante Modbus-RTU (rs485).
Por defecto, el inversor está configurado en la dirección 1. La interfaz RS485 es un conector de 4 pines en la parte inferior del inversor
detrás de una placa protectora. La posición exacta está marcada en el recuadro naranja en la imagen de abajo:

Observando más de cerca, el puerto se ve así:

Se debe usar un conector adecuado para este conector de 4 pines en el inversor Autarco para conectar al Sofar EMS. En el Sofar EMS, el inversor puede conectarse al puerto RS485. El cableado es el siguiente:

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.

Device	Sofar EMS model OM1	Sofar EMS model IG8	RS485-USB converter	RS485-Ethernet converter
Pin 3	RS485 A	RS485_POS	RS485 A	TX+
Pin 4	RS485 B	RS485_NEG	RS485 B	TX-
N/A	RS GND	GND	Not available	G

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.
