SERVSWITCH™ BRAND CAT5 EXTENDER DELAY LINE MODULE
2. Introduction
The ServSwitch™ Brand CAT5 Extender Delay Line Module can help you
overcome one of the common problems associated with video-distance extension
over twisted-pair cable. The majority of CAT5 KVM extenders use three of the pairs
in a Category 5 cable to separately send the red, green, and blue (RGB)
components of the video signal. It has often been impossible to use such extenders
with some of the newer CAT5e and CAT6 cables, and even some CAT5 cables. This
is because the different twist ratios of the three wire pairs cause the pairs to differ
significantly in total end-to-end length, which makes the RGB components of each
pixel “spread out” (arrive at the monitor at different times). This effect, known as
“delay skew,” causes visual effects such as smearing and color fringing.
When you install the Delay Line Module in series with your CAT5, CAT5e, or
CAT6 cable, it can correct many skew problems by adding user-selectable (but
imperceptible) delays to the “faster” color signals, ensuring that all RGB
components arrive at the monitor simultaneously.
The Delay Line Module comes with a 3-ft. (0.9-m) CAT5 twisted-pair patch cable
and this manual.
Before you install the Module, read

and verify whether you even
need to use it.
