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 | SmartgridOne Controller model OM1 | SmartgridOne Controller model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| RS485s TX+ | RS485 A | RS485_POS | RS485 A | TX+ |
| RS485s TX- | RS485 B | RS485_NEG | RS485 B | TX- |
| N/A | RS GND | GND | Not available | G |

配置
RS485
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 SmartgridOne Controller will find them faster!
- For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SmartgridOne Controller will scan on those first.
外部逆变器控制必须在逆变器的液晶屏幕的配置菜单中激活。
- 短按一下下方的按钮。
- 您会看到 "1. 进入设置"，长按下方的按钮 2 秒进入设置。
- 循环浏览设置，直到看到：
- Modbus 地址或
- 设置通信协议
- 长按下方的按钮 2 秒以设置地址。
- 将地址设置为所需的值。
