THE SERVSWITCH™ FAMILY
Welcome to the ServSwitch™ Family!
Thank you for purchasing BLACK BOX®ServSwitch™ Brand video equipment! We
appreciate your business, and we think you’ll appreciate the many ways that this
product will save you money, time, and effort.
Our ServSwitch family is all about breaking away from the traditional, expensive
model of computer management and display. You know, the one-size-fits-all-even-if-it-
doesn’t model that says, “One computer gets one dedicated monitor or user station, no
more, no less.” Why not a single user station (monitor, keyboard, and mouse) for
multiple computers—even computers of different platforms? Why not a pair of user
stations, each of which can control multiple computers? Why not many monitors or
user stations for the same computer? Why not access or display any of your computers,
anywhere in the world, with any of your user stations or monitors?
With our ServSwitch products, there’s no reason why not. We carry a broad line of
robust solutions for all these applications:
•
Do you have just two PCs and need an economical alternative to keeping two mice,
keyboards, and monitors on your desk? Or do you need to share many computers,
including a mix of IBM®PC, RS/6000®, Apple®Macintosh®, Sun Microsystems®,
and SGI™ types among multiple worldwide users with different access levels?
• Do you have to send video from one computer to two different local monitors? Or
do you need to send video from multiple computers to dozens of remote monitors?
•
Does your switch have to sit solidly on a worktable and use regular everyday cables?
Or does it have to be mounted in an equipment rack, use convenient many-to-one
cables, and have a rackmounted user station that folds and slides into 1U of space?
No matter how large or small your setup is, no matter how simple or how complex,
we’re confident we have a ServSwitch system that’s just right for you. The ServSwitch™
family from Black Box—the one-stop answer for all your video and KVM switching and
extension needs!

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 Appendix A and verify whether you even
need to use it.

CHAPTER 3: Installation
3. Installation
Before you install the ServSwitch™ Brand CAT5 Extender Delay Line Module,
check the compatibility list in Appendix B to make sure that your Delay Line
Module can be used immediately with your KVM or video extender, without
requiring pinning or pairing adjustments to your cables.
To install the Delay Line Module, unplug one end of the main twisted-pair cable
that runs between your extender’s transmitter and receiver units and plug it into
the Module’s RJ-45 connector marked “Interconnect”. Then run the included
patch cable from the Module’s RJ-45 connector marked “Extender” to the RJ-45
connector on the extender unit from which you unplugged the main cable.
You can place the Delay Line Module at either end of the main cable. However,
you will probably find it easier to make adjustments to your video-extension system
if you place the Module next to your extender’s remote unit.
Figure 3-1 shows a typical application with the Module installed in an extender
system.
