Troubleshooting
Nano Series GigE Vision Camera
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 Nano
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 Nano parameters such as
trigger to exposure delay.
•
USB to Ethernet adapters are not recommended nor guaranteed. Even in cases where the
camera seems to be connected and transferring images, reports of random disconnections
are common. If the user wishes to try such an interface, limit this to just one high quality
unit, never more. Multiple units have not worked in a machine vision environment.
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 Nano at maximum frame rate. If any memory overflow events
are counted, then the Nano internal buffer could not be transmitted on time and was
discarded. Such a condition may occur with large frame color or high frame rate Nano
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 Nano at a bright light source.
•
Check that the programmed exposure duration is not too short or set it to maximum.
•
Using CamExpert set the Nano to output its Internal Pattern Generator. This step is typically
done for any camera installation to quickly verify the Nano and its software package. See
Internal Test Pattern Generator for information on using CamExpert to select internal
patterns from Nano.
