### Configuration TCP

Go true the settings and give the meter a static ip and the right gateway...

### Configuration RS485

> **Warning**
>
> **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, ...)
> -   For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits.
