Info
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.

Configuratie
Waarschuwing
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.
Raadpleeg de meterhandleiding voor meer gedetailleerde informatie over het wijzigen van het Modbus-adres. Standaard staat de meter ingesteld op adres 1. Dit kan worden gewijzigd via het meterscherm.
- Gebruik de knoppen om naar Programma Modus 2 te gaan.
- Houd de rechterknop 3 seconden ingedrukt om het menu te openen.
- Scroll naar de LCD-pagina Modbus/M-bus ID (addr xxx).
- Houd de rechterknop 5 seconden ingedrukt om de programmeermodus te starten.
- De waarde begint te knipperen: selecteer 3 cijfers (Modbus: 001-247). Bevestig elk cijfer door beide knoppen 3 seconden ingedrukt te houden.
- De LCD toont OK wanneer de instelling is bevestigd.
