Autarco LD-serie RS485 ledningsføring | Sofar EMS Documentation

Denne side beskriver kommunikationen med en Autarco LD-serie hybrid inverter via Modbus-RTU (rs485). Som standard er inverteren sat til adresse 1. RS485-grænsefladen er en 4-polet stikforbindelse på bunden af inverteren bag en beskyttelsesplade. Den præcise position er markeret i den orange boks på billedet nedenfor:

Set lidt tættere på ser porten således ud:

Et passende stik bør bruges til denne 4-polet stikforbindelse på Autarco inverteren for at forbinde til Sofar EMS. På Sofar EMS kan inverteren forbindes til RS485-porten. Ledningsføringen er som følger:

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.
