Basic Operation
Picture Adjustment
Compensating for Cable Skew
In order to reduce the amount of crosstalk between twisted pairs within a shielded
CAT-5e (or better) cable, the rate of twist will vary for each twisted pair and will vary
between manufacturers. The rate of twist affects the length of each twisted pair
and is referred to as cable skew.
For example, a video signal with a single white line will appear “white” because each RGB
color component signal arrives at the same time and combines with one another to create a
solid white line, as shown below.
Figure 1.1 - Normal video signal
However, when extending a video signal over CAT-5 (or better), cable skew can cause
each color component to arrive at the destination at different times. This causes an
undesirable effect known as color divergence (separation), where one or more color
components are shifted to the left or right.

Basic Operation
EXT-VGARS232-141R
To address this issue, the VGA & RS-232 Extender provides three banks of DIP switches,
located on the bottom of the Receiver unit. Each DIP switch bank controls a specific color
component. Peel off the metallic-gray adhesive strips to expose the DIP switch banks.

Use a sharp-pointed object, such as the end of a paperclip, mechanical pencil, or small
screwdriver to slide the DIP switch to the desired position.

shielded CAT-5e (or better) cable length.
