Troubleshooting Genie_TS_Series GigE Vision Camera
 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 Genie TS frame
rate maximum will be limited once the internal buffers are filled. See the Teledyne DALSA
Network Imaging manual for information on network optimizations.
 If using an external trigger, verify the trigger source rate and Genie parameters such as
trigger to exposure delay.
 Verify the exposure mode type is Synchronous, not Reset mode. (See " Synchronization
Timing " on page 57 ).
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 from the Genie at maximum frame rate. If any memory overflow events
are counted, then the Genie internal buffer could not be transmitted on time and was
discarded. Such a condition may occur with large frame color or high frame rate Genie
cameras.
 Note that the Sapera CamExpert tool has limits to 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 that network parameters are optimal as described in the Teledyne DALSA Network
Imaging Module manual. Ensure the host computer is not executing other network intensive
tasks. Try a different Gigabit NIC.
 Note that a changed acquisition frame rate becomes active only when the acquisition is
stopped and then restarted.
Camera is functional, frame rate is as expected, but image is black
 Verify that the lens iris is open.
 Aim the Genie at a bright light source.
 Check that the programmed exposure duration is not too short or set it to maximum. See
" Sensor Control Category " on page 46 .
 Using CamExpert set the Genie to output its Internal Pattern Generator. This step is
typically done for any camera installation to quickly verify the Genie and its software
package. See " Internal Test Image Generator " on page 117 for information on using
CamExpert to select internal patterns from Genie.
Other Problems or Issues
This section describes problems that do not fit any of the categories above. Typically these are
issues found in the field under specific or unusual conditions.
Random Invalid Trigger Events
Do not change the exposure time while grabbing, else an Invalid Trigger Event may be generated.
This applies to any exposure mode or trigger source. The Invalid Trigger Event is not catastrophic
and only indicates the loss of a video frame. Stopping acquisitions first will avoid this error.
