Troubleshooting Problems

That is, the image acquisition to one frame buffer is not interrupted by any delays in transfer of the
other frame buffer (which contains the previously acquired video frame) to system memory. Note that
an application can change the number of on-board frame buffers using the Sapera LT API.
If allocation for the requested number of buffers fails, the driver will reduce the number of on-board
frame buffers requested until they can all fit. When reaching 2 on-board buffers, if they still cannot fit,
the driver will reduce the size such that it allocates two partial buffers. This mode will write image
data to the buffer while wrapping image lines around to the beginning of a buffer when full. This
mode relies on reading out the image data to the host computer faster than the acquisition.
Symptoms: CamExpert Detects no Boards
If using Sapera version 5.20 or later:
When starting CamExpert, if no Teledyne DALSA board is detected, CamExpert will start in offline
mode. There is no error message and CamExpert is functional for creating or modifying a camera
configuration file. If CamExpert should have detected the installed board, troubleshoot the installation
problem as described below.
Troubleshooting Procedure
When CamExpert detects no installed Teledyne DALSA board, there could be a hardware problem, a
PnP problem, a PCI problem, a kernel driver problem, or a software installation problem.
Make certain that the card is properly seated in the PCI slot.
Perform all installation checks described in this section (
)
before contacting Technical Support.
Try the board in a different PCI slot, if the board does not initialize.
Symptoms: X64-AN Quad Does Not Grab
You are able to start Sapera CamExpert but you do not see an image and the frame rate displayed is 0.
If your camera is powered through a camera cable, make certain that J17 on the X64-AN Quad is
connected to a floppy power cable. Otherwise, the camera must be powered using an external power
supply.
Verify the camera and timing parameters with the camera in free run mode.
Make certain that you provide an external trigger if the camera configuration file requires one.
Use the software trigger feature of CamExpert if you do not have a trigger source.
Does your camera provide a WEN signal that you need to use?
Adapt your configuration file and camera cable accordingly.
Make certain that the pinout of your camera cable matches your camera and that the camera is
properly connected to the cable.
Make certain that the camera is configured for the proper mode of operation (Composite Video,
Separate Sync, Master Mode). This must match the camera configuration file. Refer to your camera
datasheet.
