Symptoms: Card acquisition bandwidth is less than expected
The Xtium2-CXP PX8 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.
•
Is the Xtium2-CXP PX8 installed in a PCI Express x16 slot?
Note that some computer's x16 slot may only support non x16 boards at x1 or not at all. Check
the computer documentation or test an Xtium2-CXP PX8 installation. The speed at which the
board is running can be viewed using the Diagnostic Tool provided with the driver.
•
Is the Xtium2-CXP PX8 installed in a PCI Express Gen1 slot?
Some older computers only have PCIe Gen1 slots. The Generation at which the board is running
can be viewed using the Diagnostic Tool provided with the driver.
•
Is the PCI maximum payload size smaller than 256 bytes?
On some computers, this parameter can be changed in the PC’s BIOS.
Symptoms: PoCXP does not power the camera
If the Xtium2-CXP PX8 does not power the camera, do the following:
•
Ensure that a spare power supply connector from the PC power supply is connected to J10.
•
If the camera is powered by means of multiple connectors, make sure all the necessary
connections are made between the camera and the frame grabber.
•
Ensure that Power-over-CXP (PoCXP) is enabled. CamExpert can be used to verify that the
PoCXP parameter, available in the Basic Timing category, is set to Enable.
