Troubleshooting National Instruments Devices

If you are having trouble using the Image Acquisition Toolbox™ software with a supported National Instruments® frame grabber, follow these troubleshooting steps:

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

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

  2. Select Start > Programs > National Instruments > Measurement & Automation.

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

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

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

  6. With previous versions of the Image Acquisition Toolbox, the files for all of the adaptors were included in your installation. Starting with version R2014a, each adaptor is available separately through MATLAB® Add-Ons. In order to use the Image Acquisition Toolbox, you must install the adaptor that your camera uses, in this case, the NI Frame Grabbers support package. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.

  7. If your hardware is functioning properly, verify that you are using a hardware device driver that is compatible with the 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.

    • Find out the driver version you are using on your system. To learn how to get this information, see Determining the Driver Version.

    • Verify that the version is compatible with the Image Acquisition Toolbox software. For the correct driver information, check the list of supported drivers on the Image Acquisition Toolbox product page at the MathWorks Web site (

    If you discover that you are using an unsupported driver version, visit the National Instruments Web site ( to download the correct drivers.

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.
