170 Troubleshooting Linea Lite GigE Series Camera
Acquisition Error without Timeout Messages
Streaming video problems range from total loss of image data to occasional loss of random video
data packets. The following section describes conditions identified by Teledyne DALSA engineering
while working with GigE Vision cameras in various computers and setups. Refer to Teledyne
DALSAs Network Imaging Optimization Guide for information on network optimization.
No camera exposure when expected
Verify by using the camera in free-running mode. Do not use external trigger mode when
testing a camera setup.
If using free-running mode, verify that the exposure period is set to the maximum possible
for the set frame rate.
Load factory default from the Power-up Configuration in CamExpert. This will reset the
camera to its nominal acquisition rate.
Camera is functional but frame rate is lower than expected
Verify Ethernet link speed. If the LAN connection is limited to 100 Mbps, the line rate
maximum will be limited once the internal buffers are filled. Refer to Teledyne DALSA’s
Network Imaging manual for information on network optimization.
If using an external trigger, verify the trigger source rate and camera parameters such as
trigger to exposure delay.
Camera acquisition is good but frame rate is lower than expected
While running CamExpert and grabbing in free-run mode at the maximum frame rate, start
the Sapera Monitor tool from the Sapera Tools installed with Sapera.
Make sure the Memory Overflow event monitor is enabled.
Continue grabbing at maximum frame rate. If any memory overflow events are counted, the
internal buffer could not be transmitted on time and was discarded. Such a condition may
occur at high frame rate cameras.
Note: Sapera CamExpert tool limits the maximum frame rate possible due to
CamExpert generating an interrupt for each acquired frame. The Sapera Grab Demo
may be better suited for testing at higher frame rates.
Verify network parameters are optimal as described in Teledyne DALSAs Network Imaging
Package for Sapera LT Optimization Guide. Ensure the host computer is not executing other
network intensive tasks. Try a different Gigabit NIC.
Note: Changed acquisition frame rate requires the acquisition to be stopped; when
acquisition is restarted the new frame rate is applied.
Camera is functional, line rate is as expected, but image is black
Verify that the lens iris is open.
Aim the Linea Lite GigE at a bright light source.
Check the programmed exposure duration is not too short or set it to maximum. Refer to
Sensor Control Category
for relevant features.
Using CamExpert set the Linea Lite GigE to output its Internal Pattern Generator. This step is
typically done for any camera installation to quickly verify the Linea Lite GigE and its software
package. Refer to Internal Test Image Generator
section for information on using CamExpert to
select internal patterns.
