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.
2.2 Glossary
The following terms are used in this guide:
CATx Any Category 5, 5e, 6 or higher cable, solid wires type AWG24.
Although flexible AWG27/7 cables can be used too, the lengths of
flexible cables count twice in the calculation of the total distance.
Fiber 9µ Singlemode or 50µ/62,5µ Multimode fiber cable.
KVM Keyboard, Video and Mouse.
Console Keyboard, Mouse and Monitor
Dual Access A system allowing connection of Local and Remote user consoles.
Single-Head An extender system that supports one monitor + Keyboard/Mouse

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 your PC 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 attached screen or could be downloaded from remotely
located screen and stored in the internal DDC 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 transmission is terminated 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 whether
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 circumstances 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).

3.2 Interconnection Cable Requirements
To connect the Local and Remote units you will need:
•DVI, PS2-Keyboard, PS2-Mouse: Connect the supplied KVM CPU cable set to your
CPU (KVM.- Switch, etc.). Please ensure that the connection is tension-free!
•DVI, USB-Keyboard, USB-Mouse: Connect the supplied KVM CPU cable set to your
CPU (KVM.- Switch, etc.). Please ensure that the connection is tension-free!
•DVI: Connect the supplied DVI CPU cable set to your CPU (KVM.- Switch, etc.).
Please ensure that the connection is tension-free!
•CATx Cable: Recommended cable: S/UTP (CATx) according EIA/TIA 56A, TSB 36 or
Digital STP 17-03170. Four pairs AWG 24 connection according EIA/TIA 568A
(10BaseT). Use of cables from a higher category (Cat5e, Cat6, Cat7) is possible.
The use of unshielded CATx Cable is possible, because of the higher
electromagnetic noise/sensitivity the device class may not be reached
The use of flexible Cables (Patch cable) Type AWG26/7 is possible.
Because of the higher loss of the stranded cables, the maximum distance is
reduced to approx. half the value of solid cables.
A point to point connection is required. Having one or more patch panels in
the line is possible and allowed. Not allowed is a connection from the CATx
link interface (RJ45) to any other products, especially telecommunications
or network equipment.
•Fiber Cable: Two strands of fiber are required for Single-Head devices, eight strands
for Quad-Head devices.
Please note that the allowed distance will depend on device type AND on
used fiber type.
•Recommended cables:
ACSxxxxA-MM: Multimode type 50/125µ allowed distance app. 400m (1,300ft)
ACSxxxxA-MM: Multimode type 62.5/125µ allowed distance app. 200m (650ft)
ACSxxxxA-SM: Singlemode type 9/125µ allowed distance app. 10km (32,750ft)
A point to point connection is required. Having one or more patch panels
in the line is possible and allowed. Not allowed is a connection from the
Fiber link interface (LC) to any other products, especially
telecommunications or network equipment.
Our experiences show, that Singlemode devices regularly work well on
Multimode Fibers where vice versa it will never do. In addition we found,
that Singlemode devices on Multimode fibers may extend the allowed

DVI-D CATX/FIBER KVM-EXTENDER
18
distance on Multimode fibers to twice the regular length. Anyway this
cannot be guaranteed and must be evaluated by the end-user at own
expense.
•Power Supply
Connect the AC outlet jack to the Plug terminal on the front of both Local and Remote
units.
