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