Introduction
The LDV-002ESK/LDV-004ESK DVI KVM Switch is a 2-
/4-port PS/2 type KVM Switch that provides DVI
interfaces (with DVI-D Single Link connectors) to offer
genuine digital video quality for your Flat Panel
Displays. It enables the computer administrator to access,
control, boot and reboot multiple DVI-enabled computers
using only one keyboard, video and mouse. They are
designed specifically for sharing flat panel displays
between multiple PCs with DVI interfaces.
The DVI interface technology implements genuinely digital
signal transmission over the cable to reduce undesired
distortion from conventional analog/digital conversion.
Using the DVI KVM Switch with Enhanced Digital Video
Support, you can control multiple computers while enjoying
digitally clean and clear images.
Before you install
The default setting of the LDV-002ESK/LDV-004ESK DVI
KVM Switch is appropriate for most systems. In fact, you
do not need to configure the KVM Switch before
installation. It’s a Plug-and-Play device: First, connect the
keyboard, monitor and mouse to the DVI KVM switch and
then connect your computers to the KVM Switch, and
finally boot them up in correct sequence and you can start
to operate immediately! For a quick start on installation and
operation, please follow the instructions below.

Step 1. Make sure all the computers that are to be
connected to the DVI KVM Switch and their
peripherals are in powered-off state. If not, power
them off before you proceed with the following
steps.
Step 2. Connect the shared keyboard, DVI monitor/Flat
Panel Display and mouse to the console
connectors on the rear of your DVI KVM switch.
Step 3. Connect each of your computers to a PC port on
the rear of the switch. Depending on the cable you
use, the maximum cable distance is limited to at
least 5 meters (15.5 feet, with 1600 x 1200
resolution).
Step 4. Connect the external power adapter (DC9V 1A) to
the KVM Switch.
