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 Genie in various computers and setups. See the Teledyne
DALSA Network Imaging manual for information on network optimizations.
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
monochrome Genie frame rate maximum will be around 30 fps for a 640x480
exposure. Higher resolution Genie models would have even lower frame rates without
a Gigabit Ethernet connection. 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 56).
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.
•
Verify that network parameters are optimal as described in "CamExpert GigE Vision
Parameters" on page 78. Ensure the host computer is not executing other network
intensive tasks. Try a different Gigabit NIC or a PCI Express bus version.
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 "Exposure Controls" on page 51.
•
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 Image Test Patterns" on page 75 for information on
using CamExpert to select internal patterns from Genie.
