If you are having trouble using the Image Acquisition Toolbox™ software with a supported Data Translation® frame grabber, follow these troubleshooting steps:
For Data Translation devices, run the application that came with your hardware and verify that you can receive live video.
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 the Support Package Installer. In order to use the Image Acquisition Toolbox, you must install the adaptor that your camera uses, in this case, the Data Translation support package. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.
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 only compatible with specific driver versions provided by Data Translation with the Imaging Omni CD and is not guaranteed to work with any other versions.
Find out the driver version you are using on your system.
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 (www.mathworks.com/products/imaq).
If you discover that you are using an unsupported driver version, visit the Data Translation Web site (www.datatranslation.com) to download the correct driver.
If the imaqhwinfo function does not return the driver for a Data Translation frame grabber, or the imaqhwinfo function or videoinput functions return an error message about a missing DLL (olfg32.dll), you may need to install additional files from the Imaging Omni CD.
By default, when you install drivers for your Data Translation frame grabber, the installation program may not install all the files the device drivers need. The additional files needed by the device driver are part of the SDK installation, not the device driver installation. If you get error messages about missing files, insert the Imaging Omni CD into your CD-ROM drive and install the SDK.
