Autarco LH-serie RS485 bedrading | Sofar EMS Documentation

Deze pagina beschrijft de communicatie met een Autarco LH-serie hybride omvormer via Modbus-RTU (rs485).
Standaard is de omvormer ingesteld op adres 1. De RS485 interface is een 4-pins connector genaamd "COM" die zich aan de onderkant van de omvormer bevindt
achter een beschermplaat. De exacte positie is gemarkeerd in het oranje vak in de onderstaande afbeelding:

Bij nadere inspectie ziet de poort er als volgt uit:

Er moet een passende connector worden gebruikt voor deze 4-pins connector op de Autarco omvormer om aan te sluiten op de Sofar EMS.
Op de Sofar EMS kan de omvormer worden aangesloten op de RS485-poort. De bekabeling is als volgt:

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.
