Most of the setup of the software can be done from within Nexus.

We recommend that you do not run any FLIR utilities or other software that uses USB3 video cameras at the same time as Nexus.

The steps for setting up the software are:

## Check FLIR drivers

In Windows Device Manager, check that FLIR drivers are installed. They are normally installed as part of the Nexus installation.

If the device drivers are correctly installed, the camera(s) are displayed.

> ## Check cameras are displayed in Nexus
> 
> In the Nexus **System** panel, go to the **Video Cameras** section of the system tree,   
> If the cameras are connected and their drivers installed, they are displayed.
> 
> ![image](media://7a38fb93-8614-48d0-b688-ec7d740172b4)
> 
> Newly connected cameras are likely to be displayed with a yellow warning triangle, which indicates that they need the trigger to be set (see [Set the Trigger Source to the correct Vicon Lock output](#SetLockTriggerSource)).

> 
> If the camera has previously been connected, its trigger settings are remembered and its icon turns green when the Lock that is generating the trigger becomes available.

> ## Set the system frame rate
> 
> 1. On the **System** tab, select **Local Vicon System**
> 2. In the **Properties** pane below, go to the **System** section and set the **Requested Frame Rate** for the Vicon system.
> 
> The Vicon system frame rate determines which frame rates are listed for the video camera, so it makes sense to set this first.
> 
> The video frame rate cannot be higher than the system frame rate, and must divide into the system frame rate. For example, if you want 60 Hz video, set the system rate to a value such as 60 Hz, 120 Hz, 180 Hz, etc.

> ## Set the Trigger Source to the correct Vicon Lock output
> 
> To enable the Lock unit to provide a sync signal to the FLIR camera, you must set the **Trigger Source**.
> 
> ** To set the Trigger Source for the Lock unit: **
> 
> 1. On the **System** tab, go to the **Video Cameras** section and select the FLIR camera.
> 2. In the **Properties** pane, go to the **Frame Rate** section, and from the **Trigger Source** list, select the required GPO.
>   Ensure that the value that you choose in the software matches the physical cable connection. After you select the correct trigger source, the camera icon turns green after a couple of seconds.
> 
> If you select the wrong GPO, the camera does not receive any trigger signals and the video will be initially blank, or else frozen on the last frame received, and the warning icon continues to be displayed next to the camera.
