This
is due to one (or both) of
the following reasons:
Reason
#1: there is some kind of
an "electrical" problem (i.e. the video signal is not reaching the
framegrabber).
Is the camera plugged-in & turned on? Is the cable going from
the camera
properly connected (and is it connected to the correct connectors)? Is
the camera known-good?
Reason #2: Have you configured VisionGauge®
to use the proper video signal
format? If you're unsure, follow these
simple
steps to start over & specify the correct video signal format
(i.e.
the one that your camera is putting out):
Step
1: Exit VisionGauge®.
Step
2: Delete the file called "VisionGauge.cfg"
located in the main VisionGauge®
sub-directory
(probably "c:\VisionGauge\").
Step
3: Restart VisionGauge®.
Specify the same video acquisition hardware as previously, but take
special
care when specifying the video signal format.
Hint: If the cable
that you're plugging into the
video acquisition board
has a "BNC" connector on it, then you should specify a "Composite"
signal
format. If the cable that you're plugging into the video acquisition
board
has a "4 pin mini-DIN" connector on it then you should specify a "Y/C"
(or S-Video) signal format. Otherwise, you might have an RGB signal
format.
If you're unsure, repeat the above procedure & try each one of
the
possible video signal formats in turn. This "trial & error"
approach
cannot do any harm & it will allow you to solve the
problem.
