# Starting a Network Data Stream

Before establishing a TCP connection between EmotivPRO and D-Lab, you need to create a “Network Data Stream” on D-Lab software, and set up the configuration for the data channel list and IP address and port of the TCP server.

1. Open D-Lab software.
2. Click on “Plan”.
3. Click on “Recording Devices”.
4. Click on the blue plus symbol next to Network Data Stream to update the configuration.
5. Load a [D-Lab settings file which was exported from EmotivPRO](https://emotiv.gitbook.io/emotivpro-v3/d-lab-client/exporting-d-lab-settings-from-emotivpro).\
   \&#xNAN;*N.B.: You might need to change the port number here to make sure that there is a unique port number for the data stream. The port number range is from 1-65535.*
6. Click “OK” to create a TCP server.
7. Select the desired data streams.
8. Open EmotivPRO and go to Settings.
9. Click on “D-Lab Client”.
10. Click “Start”. You will now see the “Connected” status, which means you have a successful connection.\
    \&#xNAN;*N.B.: After clicking "Start", the IP address and port of the selected data stream will be saved locally, and the selection will be loaded for the next use.*

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://emotiv.gitbook.io/emotivpro-v3/d-lab-client/starting-a-network-data-stream.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
