Distorted image
No accurate video
signal due to inter-
changed video wires.
The video BUS is not protected
against polarity reversal.
Please interchange the wires V1
and V2.
The image "rolls".
The video signal can-
not be synchronized.
Please check, if all wires of the
video BUS are connected.
Eventually you have to readjust
the level.
Multiple contours occur
Image reflections
occur, so called "ghost
images", due to open
lines.
The video strand is not connected.
Please place the terminating re-
sistor in the last device of the
strand.
Contours of a second
image are visible.
Two video sources
interfere.
Please remove the second video
source from the strand.
Connect the second video source,
if necessary, via a video switch to
the existing TCS:BUS.
