10 Troubleshooting
3 Verify that your IEEE 1394 (FireWire) camera is using the Carnegie Mellon
University (CMU) DCAM driver version 6.4.4.
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 a pplication is among the files you install
fromtheCMUdriverarchivefilewhenyouinstalltheCMUDCAM
driver — see “Installing the CMU DCAM Driver” on page 10-10. To learn
how to run the demo application, see “Running the CMU Camera Demo
Application” on page 10-11.
• Ifthedemoapplicationrecognizesthe camera, the camera is set up to
use the CMU DCAM d river 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 page 10-10
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 corect 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
Image Acquisition Toolbox supports acquiring data from IEEE 1394
(FireWire) cameras that support the IIDC 1394-based Digital Camera
(DCAM) specification. To use a DCAM com pliant camera, you must use
the DCAM driver created by Carnegie Mellon Un iversity (CM U) to conne ct
to these devices.
