To test a video capture card, test its channels using the Testing video capture cards module of the Tweaki.exe utility. Do the following:

1. Shut down the Axxon PSIM software if it is started.
2. Start the Tweaki.exe utility (see the Starting and shutting-down the Tweaki.exe utility section).
3. Select the Testing video capture cards node in the tree on the left side of the utility dialog box (see The Settings panel of the Testing video capture cards section).
4. Press Test button.

The Board field will display the name of the video capture card, and the Channels state table will show the information about each channel of the card (number and status). The confirmation of successful testing will be displayed to the right of the Channels state table.
