THE DDXI - DVI/VGA KVM EXTENDER FAMILY
1
Welcome to the DDXI DVI/VGA KVM Extender
Family!
Thank you for purchasing a DDXI DVI/VGA KVM Extender model! We appreciate
your business, and we think you’ll appreciate the many ways that your enhanced
keyboard/video/mouse system will save you money, time, and effort.
That’s because our DDXI DVI/VGA KVM Extender family is all about breaking away
from the traditional, expensive model of computer management. You know the one-
size-fits-all-even-if-it-doesn’t model that says, “One computer gets one user station,
no more, no less.” Why not a pair of user stations, each of which can control multiple
computers? Why not multiple user stations for the same computer?
With our DDXI DVI/VGA KVM Extender products, there’s no reason why not. We
carry a broad line of robust solutions for all these applications. The DDXI DVI/VGA
KVM Extender family—the one-stop answer for all your KVM-extending needs!
This manual will tell you all about your new DDXi DVI/VGA KVM Extender, including
how to install, operate, and troubleshoot it. For an introduction to the Extender, see

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.
•Ensure that the system connected to the Local unit is connected to power
ground.
•Ensure that the monitor connected to the Remote unit is connected to power
ground and does not use an isolated power supply.
•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 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) or the
Fiber link interface (SC-Duplex) to any other products,
especially telecommunications or network equipment.
•To comply with CE regulations, it is NOT allowed, to use
CATx devices with unshielded CATx cables

1.1 Video Input/Output
If possible, always use DVI output from your computer’s video card and DVI input to
a monitor. This provides the optimum video signal. If you use a VGA output from your
graphic source, the DVI-KVM Local unit must digitize the signal prior to transmission.
Similarly, if your remote TFT screen uses a VGA input, it must digitize the signal from
the Remote unit. In both cases, the built-in video processors must determine the
resolution and pixel phase for an optimized digitization. Your DVI Extender allows
you to optimize the video signal manually or automatically using its on-screen utility
(see Chapter 4). If you are using a VGA input to a TFT monitor, please follow the
manufacturer’s instructions.
You may have several possible options for video source output/monitor input. If this
is the case, for the optimum video quality, please select the highest ranked available
combination from the following table:
Video Quality Local Unit input Remote Unit output
1 DVI DVI
2 DVI VGA
3 VGA DVI

2. Overview
2.1 Introduction
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 (see Figure 1). Local
units offer dual access, allowing the connection of a second user console close to the
computer. With the optional upgrade kit, you can also use DDXI DVI/VGA KVM
Extender units to communicate stereo audio and serial port signals.
DDXI DVI/VGA KVM Extender Series enables high-resolution video, PS/2 keyboard
and mouse signals to be communicated up to:
•300ft (100m) over Category 5, 5e, 6 or higher (CATx) cable.
•1200ft (400m) over Multimode fiber cable (50/125µ).
•600ft (200m) over Multimode fiber cable (62.5/125µ).
•6¼ miles (10km) over Singlemode fiber cable (9/125µ).
In a digital application (DVI input and output), there is no loss of picture quality
irrespective of extension distance and no adjustments are required. The DDXI
DVI/VGA KVM Extender Series also supports traditional analog VGA as well as
digital DVI. All combinations of DVI and VGA (graphics cards and monitors) are
supported, allowing equipment to be mixed. In a mixed analog/digital application,
some adjustment of the video signal is necessary to optimize the analog-digital signal
conversions. DDXI DVI/VGA KVM Extenders are equipped with various automatic
and manual video correction tools in an on screen utility (see page 25).
2.2 Glossary

2.6 How to Use This Guide
This guide describes the installation and configuration of the DDXI DVI/VGA KVM
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. The Remote console (keyboard,
monitor and mouse) and any audio and serial equipment connect directly to the
Remote unit.
For information about connection and installation, see Installation, page 17.
Interconnection Cable
For DVI-KVM -CAT Extenders, you will need CATx (any category 5, 5e, 6 or higher)
cable, terminated with RJ45 plugs, to connect the Local and Remote units. Other
units require singlemode or multimode fibers (see Interconnection Cable
Requirements, page 18.
Adjusting Video
Due to the digital nature of the transmitted signals, there is no distortion of video
signals or skew problem even with CATx interconnection cables.
If you do not have a DVI source and a DVI monitor, you will need to adjust the
monitor and/or the Extender to the picture width and the pixel phase. You can do this
using the Auto Adjust or Manual Adjust procedures (see page 37).
•For experienced users there is a Quick Setup section at the start of this guide
(see page 8).
•For the full procedure, see Monitor Setup (page 36) and/or Extender Setup
(page 37).

INSTALLATION
19
3.3 System Setup
To install your DDXI DVI/VGA KVM Extender system:
1. Switch off all devices.
2. Connect your keyboard, monitor(s) and mouse to the Remote unit as shown in
Figure 2 (K439-1W), Figure 4 (K437-1W/K438-1W) or Figure 6 (K442-2U/K443-
2U).
These ports may also be attached to the CPU side of a KVM
switch in order to have a Remote CPU. However, if you are
attempting to use the extender between cascaded KVM switches this
may not work. Please contact Technical Support to discuss your
application.
3. Connect the interconnect cable to the INTERCONNECT socket(s) as shown in
Figure 2 (K439-1W), Figure 4 (K437-1W/K438-1W) or Figure 6 (K442-2U/K443-
2U).
4. Connect the 6V power supply to power the unit.
Only use the power supply originally supplied with this
equipment or a manufacturer-approved replacement.
5. Using the supplied CPU KVM cable(s), connect the keyboard, monitor(s) and
mouse connectors on the computer (or KVM switch) to the corresponding
connectors on the Local unit as shown in Figure 3 (K439-1W), Figure 5 (K437-
1W/K438-1W) or Figure 7 (K442-2U/K443-2U).
Ensure that you attach the keyboard and mouse connectors to the correct ports.
The keyboard connector is purple; the mouse connector is green.
If your PC does not have a PS/2 mouse port, an active serial
converter will be required
6. For a dual access system, connect the keyboard, mouse and monitor for the
Local console to the appropriate ports on the Local unit. The ports may also be
used to feed into a KVM switch.
7. Connect the Interconnection cable from the Remote unit to the
INTERCONNECT socket on the Local unit as shown in Figure 3 (K439-1W),
Figure 5 (K437-1W/K438-1W) or Figure 7 (K442-2U/K443-2U).
8. Power up the system.
