dcam or winvideo adaptors. If you can connect to your camera from the toolbox
but cannot access some camera features, such as hardware triggering, you might
be accessing the camera through a DirectX
®
driver. See “Creating a Video Input
Object” on page 5-9 for more information about specifying adaptors.

Verify that your IEEE 1394 (FireWire) camera is using the Carnegie Mellon
University (CMU) DCAM driver version 6.4.6.
Note The toolbox only supports connections to IEEE 1394 (FireWire) DCAM-
compliant devices using the CMU DCAM driver. The toolbox is not compatible with
any other vendor-supplied driver, even if the driver is DCAM compliant.
To verify this, run the demo application provided by CMU, 1394CameraDemo.exe.
This demo application is among the files you install from the CMU driver archive
file when you install the CMU DCAM driver — see “Installing the CMU DCAM
Driver on Windows” on page 16-10. To learn how to run the demo application, see
“Running the CMU Camera Demo Application on Windows” on page 16-11.
• If the demo application recognizes the camera, the camera is set up to use the
CMU DCAM driver and is ready for use by the toolbox.
• If the demo application does not recognize the camera, install the CMU DCAM
driver. See “Installing the CMU DCAM Driver on Windows” on page 16-10 for
instructions.
• If the demo application recognizes your camera, but the toolbox still does
not, verify that the camera complies with the correct DCAM specification
version for the camera and the correct DCAM CMU driver version required
by the toolbox. For the correct information about supported hardware, visit
the Image Acquisition Toolbox product page at the MathWorks Web site
(www.mathworks.com/products/imaq).
Installing the CMU DCAM Driver on Windows
The Image Acquisition Toolbox software supports acquiring data from IEEE 1394
(FireWire) cameras that support the IIDC 1394-based Digital Camera (DCAM)
specification. To use a DCAM compliant camera, you must use the DCAM driver created
by Carnegie Mellon University (CMU) to connect to these devices.
