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
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.
•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
4 VGA VGA
