Welcome to the DVI-D Cat X KVM-Extender
Family!
Thank you for purchasing an DVI-D Cat X KVM-Extender! We appreciate your business,
and we think you’ll appreciate the many ways that your enhanced RGB Graphic system will
save you money, time, and effort.
That’s because our DVI-D Cat X KVM-Extender is all about breaking away from the
traditional model of attaching a new display to DVI graphic source. Using the DVI-D Cat X
KVM-Extender, you can remotely locate monitor, keyboard and mouse up to 140m away
from your CPU.
Wherever long distances are required, e.g. airports, industrial plants, call- centres or in
distributed computer centres, the DVI-D Cat X KVM-Extender is the best way, to solve all
problems in remotely locating your console. 4 different types are available: Singlehead and
Dualhead devices for PS2 keyboard/mouse and Singlehead and Dualhead devices for USB
keyboard/mouse.
This manual will tell you all about your new DVI-D Cat X KVM-Extender, including how to
install, operate, and troubleshoot it. For an introduction to the Converter, see Chapter 2. The
Converter product codes covered in this manual are:

Safety Precautions and Installation Guidelines
To ensure reliable and safe long-term operation, please note the following installation
guidelines:
•Do not use CATx-devices to link between buildings – please use fiber devices.
•Only use in dry, indoor environments.
•If the building has 3-phase AC power, try to ensure that equipment connected to the
Local and Remote units is on the same phase.
•Try not to route a CATx link cable alongside power cables.
•The Remote unit, Local unit and any power supplies can get warm. Do not locate them
in an enclosed space without any airflow.
•Do not place a power supply directly on top of a unit.
•Do not obstruct a unit’s ventilation existing holes.
To safeguard against personal in ury and avoid possible
damage to equipment or property, please observe the
following:
•Only use power supplies originally supplied with the
product or manufacturer-approved replacements. Do not
attempt to dismantle or repair any power supply. Do not
use a power supply if it appears to be defective or has a
damaged case.
•Connect all power supplies to grounded outlets. In each
case, ensure that the ground connection is maintained
from the outlet socket through to the power supply’s AC
power input.
•Do not attempt to modify or repair this product, or make
a connection from the CATx link interface (RJ45) to any
other products, especially telecommunications or
network equipment.

OVERVIEW

2. Overview
2.1 Introduction
A CatX KVM Extender is mainly used, to extend the maximum distance between a CPU
and his Keyboard / Monitor / Mouse considerably. In addition they are beneficial in
installations in electromagnetic hazardous environments (EMI). Normal Keyboard-/
Monitor-/ Mouse extender cables (and Extender using traditional cables) cannot go so far
and EMI interferences may reduce the maximum distance and/or reliability. Using a
DVI-D Cat X Extender system, these limitations are past. Retain your CPU in a secure
rack cabinet or data center while accessing from a 140m remotely located place.
A basic KVM extension system comprises a Local unit (transmitter) and a Remote unit
(receiver). The Local unit connects directly to the computer (or a KVM switch system) using
the supplied cable(s). The user console (keyboard, mouse and monitor) attaches to the
Remote unit. The Remote and Local units communicate video and data information along the
interconnecting cable. Local units offer dual access, allowing the connection of a second user
console close to the computer.
