# Create The Observer XT settings

## Aim

To enable communication between The Observer XT and N-Linx Server.

### Prerequisites

- You installed N-Linx Server on a computer in the network.
- If MediaRecorder and The Observer XT, or N-Linx Server run on different computers, you created exceptions for the port that N-Linx uses in Windows Firewall.  
    See [Create exceptions for N-Linx port in Windows Firewall](https://bookstack.noldus.com/link/444#bkmrk-page-title)

- N-Linx Agent is installed on the computer with MediaRecorder and connected to N-Linx Server.  
    See [Install N-Linx Agent](https://bookstack.noldus.com/link/446#bkmrk-page-title)

- MediaRecorder is open.

## Procedure

1. In The Observer XT, choose **File** > **Preferences** > N-**Linx Settings**.
2. Select **Use N-Linx server to connect with other applications.**[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/upybTfl4x7liMaQz-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/upybTfl4x7liMaQz-image.png)
3. In the N**-Linx Server address** field, enter the computer name of the computer with N-Linx server. If The Observer XT is installed on the same computer as N-Linx Server, leave the default entry Localhost.
4. In the **N-Linx Server port** field, leave the default port 5672. Ask your system administrator for assistance if this port is used by another program.
5. Click **Test connection**. If connection with N-Linx Server is found, the **Status** will change to **Connected**.
6. Click **OK**.
7. Choose **Setup** > **Project Setup**.
8. Under Observation source, select Live Observation. The Devices window now opens. If not, click the **Devices** button.[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/sHrNM2RO39SIPTgf-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/sHrNM2RO39SIPTgf-image.png)
9. Select **MediaRecorder \[Version number\]\[Computer name\]** and click **Edit Settings**. MediaRecorder now opens if it is not already open.

10. Click **Edit Settings** again. A window with the available configurations (see [Save the camera settings](https://bookstack.noldus.com/link/434#bkmrk-page-title) in [Record video](https://bookstack.noldus.com/link/439#bkmrk-page-title)) now opens. Select the configuration file you want to use and click **OK**. If you do not select a configuration, **Current Settings.mrs** will be used.  
    Optionally enter a unique name in the **Identify device** as field. This way you can control multiple instances of MediaRecorder with one instance of The Observer XT.

11. Repeat the steps 9 and 10 for each MediaRecorder instance.

## Note

When you close MediaRecorder, the MediaRecorder line in the **Devices** window (step 9) will be grayed out and the status will change to **Disabled**. MediaRecorder will start when you create an observation.
