Welcome to the DVI-D CATx/Fiber KVM-

Extender Family!

Thank you for purchasing a DVI-D CATx/Fiber 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 CATx/Fiber KVM-Extender is all about breaking away from the
traditional mo del of attaching a new display to DVI graphic source. Using the DVI-D
CATx/Fiber KVM-Extender, you can remotely locate monitor, keyboard and mouse up to
140m (@ CATx) away from your CPU. Singlemode fibers allow up to 10km!

Wherever long distances are required, e.g. airports, industrial plants, call- centres or in
distributed computer centres, the DVI-D CATx/Fiber KVM-Extender is the best way, to solve
all problems in remotely locating your console. 2 families with 4 different types are available:
Quad-Head devices for USB HID or USB 2.0 transparent – CATx, Multimode, Singlemode
and CWDM.

This manual will tell you all about your new DVI-D CATx/Fiber KVM-Extender, including
how to install, operate, and troubleshoot it. For an introduction to the Extender, see Chapter

2. The Extender 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 injury 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

2. Overview

2.1 Introduction

A CATx/Fiber 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 CATx 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 and a Remote unit. 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 cables. Local
units offer dual access, allowing the connection of a second monitor close to the computer.

Human Interface Devices are units, which are used for human access
to the CPU. They are a USB-device class of its own (e.g. Memory
Devices etc.). Besides of keyboard and mouse also touchscreen, light
pen, fingerprint sensor, graphic tablets etc. are HID devices

2.6 How to Use This Guide

This guide describes the installation and configuration of the DVI-D CATx/Fiber – Extender
Series. Although the connection and operation of the system is relatively straightforward, you
should consider the following before getting started:

Connection & Compatibility

If you have purchased an Extender Kit, this will contain all the cables required to connect the
Local unit to you r P C or KVM switch. Please see also: Package Contents (page 15)

For information about connection and installation, see Interconnection Cable
Requirements, page 17.

DDC Information

Normally it is not necessary to make any adjustments to the DVI-D CATx/Fiber- Extender.
However, in some circumstances, it may be necessary to redefine the source of DDC
Information for the CPU. By default, the DVI-D CATx/Fiber KVM-Extender uses its own
internal DDC table. If this setting does not satisfy your requirements, the DDC table can
either be switched to the locally attach ed screen or could be downloaded from remotely
located screen an d sto red in the internal DD C table.

To modify the DDC-Setup, see Service Setup (page 27).

Selecting the moment of switching to the next frame

The transmission of screen data is not synchronous to the screen change of the graphic card.
Normally, the tr an smission is term inated during displaying a frame on the screen. If the
device switches to the new frame during the displaying period of the old frame (somewhere
on the screen), it’s possible, and that you can see horizontal screen breaks in the moment of
switching (default). On the other hand the device must idle, until the actual frame is displayed
completely (until VSYNC) -> the number of frames per second transmitted sinks.

To modify the switching behaviour, see Service Setup (page 27).

Selection of Color reduction for transfer acceleration

You can select, whether always 24 Bit colors (=full color depth) are transmitted or wheth e r
the compression algorithm automatically switches between 16 and 24 Bit colors to accelerate
the data transfer (default). Normally the difference between 24 Bit and 16 Bit is not
recognizable but under some special cir cumst ances e.g. in photo processing installations there
might be disturbing color aberrations. However, the automatic color switching enhances the
count of frames; transmitted per second, fixed 24 Bit color depth gives smooth color grades
under all circumstances. Please select to you choice the better mode.

To modify the color depth, see Service Setup (page 27).

INSTALLATION

3. Installation

For first-time users, we recommend that you carry out a test placement, con fin ed to a single
room, before commencing full installation. This will allow you to identify and solve any
cabling problems, and experiment with the KVM extender system more conveniently.
