Troubleshooting National Instruments Devices

If you are having trouble using the Image Acquisition Toolbox™ software with a supported National Instruments™ frame grabber, try the following:

  1. Install the Image Acquisition Toolbox Support Package for National Instruments Hardware.

    Starting with version R2014a, each adaptor is available separately through MATLAB® Add-Ons. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.

  2. Verify that your image acquisition hardware is functioning properly.

    For National Instruments devices, run the application that came with your hardware, NI MAX (Measurement & Automation Explorer), and verify that you can receive live video.

    Launch NI MAX from Start > Programs > National Instruments > NI MAX.

    To test that the hardware is working properly, in Measurement & Automation Explorer, expand Devices and Interfaces, and then expand NI-IMAQ Devices, and expand the node that represents the board you want to use.

    With the board expanded, select the channel or port that you have connected a camera to.

  3. Click the Grab button to verify that your camera is working. If it is not, see the National Instruments device documentation.

  4. Confirm that the NI-IMAQ vendor driver version installed is supported by Image Acquisition Toolbox.


    The Image Acquisition Toolbox software is compatible only with specific driver versions provided with the National Instruments software and is not guaranteed to work with any other versions.

  5. If you discover that you are using an unsupported driver version:

    • Uninstall any existing NI-IMAQ driver version from Windows Control Panel > Programs and Features > National Instruments Software.

    • Reinstall the Image Acquisition Toolbox Support Package for National Instruments Hardware.

Determining the Driver Version for National Instruments Devices

To determine the National Instruments driver version you are using, run the Measurement & Automation Explorer.

Select Help > System Information, and then see the NI-IMAQ Software field for the driver version number.
