Data Translation Hardware
If you are having trouble using the Image Acquisition Toolbox software with a supported
Data Translation frame grabber, follow these troubleshooting steps:
1
Verify that your image acquisition hardware is functioning properly.
For Data Translation devices, run the application that came with your hardware and
verify that you can receive live video.
2
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” on page 4-2 for information about
installing the adaptors.
3
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.
4
Install the Data Translation Software Development Kit (SDK).
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
