Run the tool from the Windows Start menu: Start•Programs•Teledyne DALSA•Sapera
Network Imaging Package•Dalsa Network Configuration Tool. Verify the camera appears as
a child of the NIC card it is connected to. By default the camera is identified by its serial number if
no user defined name has been assigned.
Quick Startup with CamExpert
When the Linea GigE camera is connected to a Gigabit network adapter on a host computer, testing
the installation with CamExpert is a straightforward procedure.
Start Sapera CamExpert by double clicking the desktop icon created during the Sapera
•
installation.
CamExpert will search for installed Sapera devices. In the Device list area on the left side, the
•
connected Linea GigE camera is shown or will be listed in a few seconds after CamExpert
completes the automatic device search (device discovery).
Select the Linea GigE device by clicking on the camera user defined name. By default the
•
camera is identified by its serial number. The Linea GigE status LED will turn green, indicating
the CamExpert application is now connected.
Camera defaults will set AcquisitionLineRate="20000" Hz, TriggerMode=Off,
•
ExposureMode=Timed, and ExposureTime="9.71" microsecond.
•
Click on the Grab button for live acquisition (the Linea GigE factory default is Internal Trigger
mode with a vertical height parameter which defines the virtual image frame). See "Operational
Reference" on page 24 for information on CamExpert parameters with the camera.
If the Linea GigE has no lens, just select one of the internal test patterns available (Image
•
Format Controls – Test Image Selector). The CamExpert feature selection and the grabbed
pattern are shown below.
Note that CamExpert cannot grab at high virtual frame rates due to it generating an interrupt
•
for each virtual video frame. The Sapera Grab Demo tool is better suited for high frame rates.
•
If the AcquisitionLineRate is reduced and/or frame buffer Height is increased, then you may
need to increase the value for the GigE Vision Host Control feature "Image Timeout".
Refer to the Teledyne DALSA Network Imaging package manual if error messages are shown in
•
the Output Messages pane. Try increasing the value of the Linea GigE Interpacket Delay feature
available from the GigE Vision Transport Layer Category group in CamExpert. An increase from
default may correct errors with NIC interfaces that do not have adequate performance.
