Troubleshooting DCAM IEEE 1394 Hardware
If you are having trouble u sing Image Acquisition Toolbox with an IEEE
1394 (FireWire) camera, using the toolbox’s
dcam adaptor, follow these
troubleshooting steps:
1 Verify that your IEEE 1394 (FireWire) camera is plugged into the IEEE
1394 (FireWire) port on your computer and is powered u p.
2 Verify that your IEEE 1394 (FireWire) camera can be accessed through
the
dcam adaptor.
• Make sure the camera is compliant with the IIDC 1394-based Digital
Camera (DCAM) specification. Vendors typically include this information
in do cumentation that comes with the camera. If your digital camera is
notDCAMcompliant,youmightbeabletousethe
winvideo adaptor.
See “Troubleshooting Windows Video Hardware” on page 10-23 for
information.
• Make sure the camera o utputs data in uncompressed format. Cameras
that output data in Digital Video (DV) format, such as digital camcorders,
cannot use the
dcam adaptor. To access these devices, use the winvideo
adaptor. See “Troublesh ooting Windows Video Hard ware” on pag e 10-23
for information.
• Make sure you specified the
dcam adaptor when you created the video
input object. Some IEEE 1394 (FireWire) cameras can be accessed
through either the
dcam or winvideo adaptors. If you can connect to your
camera from the toolbox but cannot access some cam era features, such
as hardware triggering, you might b e acces sing the camera through a
DirectX driver. See “Creating a Video Input Object” on page 4-10 for
more information about specifying adaptors.
