Troubleshooting Problems
X64-AN Quad User's Manual
Try using a standard video source (RS-170 or CCIR). This validates that X64-AN Quad is able to
grab and may point to a problem with your camera configuration file.
Try to snap one frame instead of continuous grab.
Perform all installation checks described in this section (
)
before contacting Technical Support.
Symptoms: Card grabs black
You are able to use Sapera CamExpert, the displayed frame rate is as expected, but the display stays
black.
Set your camera to manual exposure mode and set the exposure to a longer period plus open the
lens iris.
Try changing Contrast/Brightness settings.
Try changing the clamping setting (DC restoration) if it is not a standard video source
configuration file and the camera file was not supplied by Teledyne DALSA.
Try using a standard video source (RS-170 or CCIR). This validates that X64-AN Quad is able to
grab and may point to a problem with your camera configuration file.
Try to snap one frame instead of continuous grab.
Make certain that the input LUT is not programmed to output all ‘0’s.
This problem is sometimes caused by a PCI transfer issue. No PCI transfer takes place, so the
frame rate is above 0 but nevertheless no image is displayed in CamExpert.
Make certain that BUS MASTER bit in the PCI configuration space is activated. Look in PCI
Diagnostics for
BM
button under “Command” group. Make certain that the
BM
button is activated.
Perform all installation checks described in this section (
)
before contacting Technical Support.
Symptoms: Card acquisition bandwidth is less than expected
The X64-AN Quad acquisition bandwidth is less than expected.
Review the system for problems or conflicts with other expansion boards or drivers.
Remove other PCI Express, PCI-32 or PCI-64 boards and check acquisition bandwidth again.
Engineering has seen this case where other PCI boards in some systems cause limitations in transfers.
Each system, with its combination of system motherboard and PCI boards, will be unique and must be
tested for bandwidth limitations affecting the imaging application.
