Table B-4: Operational Troubleshooting
Problem Suggestion
The camera appears to be
working (LEDs blinking
intermittently), but I can’t
access it to get an image.
Ensure that the camera has an IP address. Ping the IP address that you think belongs to the
camera and wait for a reply. For example:
(UNIX) % ping 192.0.1.123
(DOS) C: PING 192.0.1.123
Ensure that the camera s IP address is unique to the network. You may need to consult your
system administrator for assistance. Also, check your host’s ARP table for an entry that
includes the camera’s hardware address, and make sure the IP address of that entry matches
the address you are using to access the camera.
Check the Activity LED. If it only blinks once every thirty seconds, there is probably a
problem with your Ethernet connection. Check your cable connections and hardware.
If you are connecting to the Ethernet via a hub or repeater, ensure that you are using a
functional port and that the hub or repeater is connected properly to the network.
Ensure that you are using Netscape Navigator 4.7 or higher or Microsoft Internet Explorer
5.5 or higher.
I can access the camera and
get an image, but the image
is blank/all black/all white.
Ensure that the lens cap is off and that there is nothing blocking the lens. If necessary,
unscrew your lens and ensure that there is nothing inside the lens mount area obscuring the
imager.
Note: Do not touch the imager.
Ensure that the lens is in a location that receives some light, but is not in the direct path of a
strong light source.
If the lens has an iris, make sure that it is at least partially open.
There are spots/streaks/
horizontal lines in my
images.
Try changing the Image Settings, especially SET/DEFINE IMAGE LIGHTING
FREQUENCY (see the Image Configuration chapter of the Reference Manual).
Check the lens for dust, scratches, smudges, or other problems. If necessary, clean the lens
with a piece of lens paper.
There is static in my
images.
Increase the amount of light in your camera s environment. Static most often appears in dark
scenes.
Check for electromagnetic interference. Excess interference can lead to poor image
acquisition and/or processing as well as visible static.
Check your image resolution and compression settings. Low resolution, high-compression
imaging may result in pixellation or noise.
My images are too red/
green/blue.
Adjust the default lighting settings. Set the value to match the light source that illuminates
your camera s surroundings. If this value is set improperly, the colors in your image may
appear out of balance.
Try changing the Image Settings, especially the auto color correction command
SET/DEFINE IMAGE LIGHTING AUTO ENABLED (see the Image Configuration
chapter of the Reference Manual).
My images are blurry.
Focus the camera. Refer to the Focus section for information.
Fast-moving subjects may appear blurred as a result of imaging hardware limitations.
Once I connected a trigger
to my camera, the camera
no longer functions
properly.
Make sure that your sensor device is not taking more than 50 mA of current from the Relay
Power Out pin of the screw terminal. If so, choose a new trigger device.
