- Configuration changes must be saved and the API restarted
---
### Configuration Steps
1. Navigate to the **General Options** tab under
`/configuration/apisettings`.
- In the standard output of the API a log message will inform if the connection was sucessful - if not the API will continously attempt to connect
2. Enter the **IP Address** and **Port** of your KNX IP Tunnel.
- Alternatively the "datapoint/values" endpoint will respond with status code 504 Gateway Timeout if no connection is currently available
3. Click **Save Changes**.
4. Restart the API to apply the configuration.

### Connection Feedback
- After saving and restarting, a log message will appear in the **API's standard output**, indicating whether the connection was successful.
- If the connection fails, the API will continuously attempt to reconnect.
- Alternatively, requests to the `/datapoint/values` endpoint will return a
**504 Gateway Timeout** status if no connection is available.
> **Note:** If the **"Activate Simulator"** option is enabled in the **Simulator Options** tab, the API **will not attempt** to connect to a KNX Interface.

Note: If the box "Activate Simulator" is checked in the Simulator Options tab the API will not connect to a Knx Interface
