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.
| Device | Sofar EMS model OM1 | Sofar EMS model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| D1 (+) | RS485 A | RS485_POS | RS485 A | TX+ |
| D0 (-) | RS485 B | RS485_NEG | RS485 B | TX- |
| 0V / Shield | RS GND | GND | Not available | G |
Se venligst enhedens manual for de nøjagtige pin-lokationer, da disse kan variere lidt mellem specifikke undermodeller (f.eks. iEM2150 vs iEM2155).
Konfiguration
Advarsel
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.
Kommunikationsindstillinger
Sørg for, at enhedens indstillinger matcher driverens kapaciteter som defineret nedenfor:
- Baudhastighed: 9600, 19200 eller 38400 (Standard er ofte 19200)
- Paritet: Jævn, Ulige eller Ingen
- Stopbits: 1
- Databits: 8
Tjek enhedens manual for, hvordan du går ind i energimålerens konfigurationsmenu for at sætte Modbus-adressen og baudhastigheden.
