Trouble Shooting
Check the Basics
o
Is power available? Check the status LED 2. If the LED is off, the camera is not getting power.
Verify the connections and cabling.
o
Is the LED 2 flashing once per second? This occurs if the firmware is corrupt because a firmware
update was interrupted. If this is the case, run the firmware updater again, carefully following
the instructions. If the problem persists, contact AVT.
o
Is the LED flashing 3 times once per second? This indicates a fault with the camera. If this
problem persists, please contact AVT.
Test the Camera with the AVT Viewer
Download and install the AVT Viewer (from
http://www.alliedvisiontec.com/us/support.html
).
o
Can the Viewer find the camera? Is the camera listed in the main application window or is the
list empty? If the camera is not listed, proceed to
Driver Issues
.
o
Is the image black? If so, check the optics. Check that lens iris is fully open. Check exposure
time - in room lighting, an exposure time of 30ms should be adequate to see an image. If
image is still black, contact AVT.
o
Is the image white?
•
If the camera is in external trigger mode, a snapshot will not complete until a hardware
trigger is received.
•
Image data may fail to arrive at the computer if there is a problem with the driver. If
you suspect a driver problem, proceed to
Driver Issues
.
o
Is the image white, but the camera is not waiting for an external trigger? Do you have a lens?
Check your exposure time, offset, and gain controls.
o
Does the image occasionally freeze? Test the camera with an alternate Ethernet cable and
card. If the problem persists, contact AVT.
•
An intermittent connection will result in the loss of image data, but you likely will not
notice a problem when using the camera controls.
Driver Issues
TBD.
Camera will not trigger
Check cabling and connections. Verify that external trigger circuit is providing a compatible
trigger signal. Use the AVT Viewer program in trigger mode to eliminate possible software issues.
