DALSA Sapera Hardware

Troubleshooting DALSA Sapera Devices

The Image Acquisition Toolbox™ software supports the use of DALSA® Sapera hardware.

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

  1. Install the Image Acquisition Toolbox Support Package for DALSA Sapera 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. Install the third-party hardware device driver separately and verify that it is compatible with Image Acquisition Toolbox. For the correct driver information, check the list of supported drivers for your MATLAB release under Third-Party Requirements on Teledyne DALSA Support from Image Acquisition Toolbox.


    Image Acquisition Toolbox is compatible only with specific driver versions provided with the DALSA Sapera hardware 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 for DALSA Sapera Devices.

    If you discover that you are using an unsupported driver version, visit the Teledyne DALSA website to download the correct driver.

  3. Use the imaqhwinfo function to verify if 'dalsa' is listed.

      ans = 
        struct with fields:
        InstalledAdaptors: {'dalsa'  'winvideo'}
            MATLABVersion: '9.4 (R2018a)'
              ToolboxName: 'Image Acquisition Toolbox'
           ToolboxVersion: '5.3 (R2018a)'

    In the example shown, the DALSA and WinVideo adaptors are present, meaning the DALSA and OS Generic Video Interface support packages are installed.

  4. Verify that you have a supported frame grabber. See a list of supported frame grabbers on Teledyne DALSA Support from Image Acquisition Toolbox.

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

    For DALSA Sapera devices, run the application that came with your hardware, the Sapera CamExpert, and verify that you can view a live video stream from your camera.

    If you are using a camera file to configure the device, verify that the toolbox can locate your camera file. Make sure that your camera appears in the Camera list in the Sapera CamExpert. To test the camera, select the camera in the list, and click the Grab button.

  6. Make sure no other application is using the camera.

Determining the Driver Version for DALSA Sapera Devices

To determine the DALSA Sapera Library version you are using, view the release notes for the driver. You can access the release notes through the Windows® Start menu.

  1. Click the Start button to open the Start menu.

  2. Select Programs > DALSA Coreco Imaging > Sapera LT to open the Sapera LT menu.

  3. Select Readme to view the Sapera release notes.
