Welcome to the CATX DVI-D Family!
Thank you for purchasing a CATX DVI-D Switch! We appreciate your business, and we
think you’ll appreciate the many ways that your CATX DVI-D system will save you money,
time, and effort.
The CATX DVI-D Switch offers three fundamental uses:
• As a Multiplex Repeater: the DVI signals (+optional audio) coming from a signal
source are equalized and distributed on up to 7 equivalent outputs. A control is not
necessary. Distributed display systems can be realized (Digital Signage).
• As an 8-port Crosspoint Switch: each port can be switched optionally as an input or
output. You can, for example, switch and distribute the signals from 3 signal
sources on up to 5 displays (allowing simultaneous presentations on several
displays). Alternatively, signals coming from 7 signal sources can be switched in
turn to a single display. The changeover can be triggered remotely using the serial
interface (RS232) and/or by a push-button at the device.
• As a 7-port KVM Switch: up to 7 Singlehead ports (a “Singlehead” extender system
supports 1x monitor, 1x keyboard, 1x mouse) or up to 3 Dualhead ports (a
Dualhead extender system supports 2x monitor, 1x keyboard, 1x mouse). The
changeover can be triggered remotely using the serial interface (RS232) and/or by a
push-button at the device.
Cascade multiple devices in two stages for all applications to give up to 49/1 connections.
The CATX DVI-D Switch has the advantage that it can be positioned up to 140m away from
both your signal source and display device. This becomes possible by using the proven
CATX DVI-D- Extender technology for the transmission of DVI- Monitor and USB-
Keyboard and Mouse signals over CATx- cable.
The operation of a CATX DVI-D Switch always requires at least one Local Unit and up to
seven Remote Units from the CATX DVI-D-Extenders range.

Wherever long distances cause problems for remotely locating and switching a monitor
(keyboard/mouse) signal, e.g. airports, industrial plants, call centres or in distributed
computer centres, the CATX DVI-D Switch is the best solution. Its flexibility allows it to
tackle many tasks.
In addition, there are 4 Media Extenders (DVI + optional audio) and 8 KVM- Extenders
(DVI+USB keyboard mouse + optional audio) available. The transmission of the signals
requires connecting CATx cable.
This manual will tell you all about your new CATX DVI-D Switch, including how to install,
operate and troubleshoot it. For an introduction to the Converter, see Chapter 2.

2. Overview
2.1 Introduction
The CATX DVI-D Switch can be set up in three configurations:
• As a Multiplex Repeater: - the DVI signals (+optional audio) coming from a
signal source are equalized and distributed on up to 7 equivalent outputs. A control
is not necessary. Distributed display systems can be realized (digital signage).
There are three operating modes: 1 link (1 source to 7 screens), 2 links (1 source to
3 screens each) and 4 links (1 source to 1 screen each): a pure length booster.
• As an 8-port Crosspoint Switch: each port can be switched optionally as an input
or output so you can, for example, switch and distribute the signals from 3 signal
sources on up to 5 displays (allowing simultaneous presentations on several
displays). Alternatively, signals coming from 7 signal sources can be switched in
turn to a display. The changeover can be triggered remotely using the serial
interface (RS232) and/or by a push-button at the device.
• As a 7-port KVM Switch: up to 7 Singlehead switches (a “Singlehead” extender
system supports 1x monitor, 1x keyboard, 1x mouse) or up to 3 Dualhead switches
(a Dualhead extender system supports 2x monitor, 1x keyboard, 1x mouse). The
changeover can be triggered remotely using the serial interface (RS232) and/or by a
push-button at the device.
A Multiplex Repeater system comprises a CATX DVI-D Switch and one or more
Local/Remote Units. Optionally, several CATX DVI-D Switches can be cascaded in
maximally two stages (master/slave). The CATX DVI-D Switch and the Local/ Remote Units
are attached by CATx interconnection cables.
The operation of a CATX DVI-D Switch always requires (at least) one Local Unit of a CATX
DVI-D-Extender and up to seven Remote Units of CATX DVI-D-Extenders.

2.7 How to Use This Guide
This guide describes the installation and configuration of the CATX DVI-D Switch. Although
the connection and operation of the system is relatively straightforward, you should consider
the following before getting started:
Connection & Compatibility
The individual CATX DVI-D Switch components consist of:
• CATX DVI-D Switch for CATx: includes the device and power supply.
• CATX DVI-D- KVM Local Unit: includes the device, power supply and all the cable
required to connect the CATX DVI-D- KVM/ Media Local Unit to your CPU/ Signal
source.
• CATX DVI-D- KVM Remote Unit: includes the device and power supply
Please see also Package Contents (Page 19).
For information about connection and installation, see page 21.
DDC Information
Normally it is not necessary to make any adjustments to the CATX DVI-D- KVM/ Media
device. However, in some circumstances, it may be necessary to redefine the source of DDC
information for the CPU. By default, the CATX DVI-D- KVM/ Media uses its own internal
DDC table. If this setting does not satisfy your requirements, the DDC table can either be
switched to the locally attached screen or can be downloaded from the remotely located
screen and stored in the internal DDC table.
To modify the DDC-Setup, see Setup at the Local Unit (Page 45).
Selecting the moment of switching to the next frame
The transmission of screen data is not synchronous to the screen changes of the graphic card.
Normally, the transmission is terminated during the display of a frame on the screen (at the
remote unit). If the device switches to the new frame during the displaying period of the old
frame (somewhere on the screen), it is possible that you will see horizontal screen breaks at
the moment of switching (default). On the other hand, if the device idles until the actual
frame is displayed completely (until VSYNC) then the number of frames per second
transmitted reduces.
To modify the switching behaviour, see Setup at the Remote Unit (Page 48).
