Introduction
The
LDV-DM202AUSK/LDV-DM204AUSK
is a 2/4-port Dual
Monitor DVI KVM Switch designed for sharing two DVI
monitors/Flat Panel Displays between multiple multimedia
computers with Dual Head display [2 x DVI]. Its audio and mic
switching feature gives you an uninterrupted audio experience
that maximizes your multimedia
application with KVM
operation.
The
2 extra USB 2.0 hub ports
are for sharing high-speed
USB 2.0 devices.
In addition to the keyboard hotkey operation, it provides an
innovative and easy-to-use
KVM Switcher Software (for
Windows/Mac)
-- a small software client application to
facilitate your KVM switching operations such as PC selection
and hotkey sequence programming, autoscanning, autoscan
delay
time
programming,
independent/simultaneous
audio&PC switching, etc. User can use either the original
keyboard hotkey or the KVM switcher client software to
facilitate KVM operation.
Out-of-the-box Installation
Take the KVM Switch out of the box and begin
installation….
Step 1.
Power up your KVM Switch by connecting the external
power adapter to it.
Step 2.

monitors and the speaker system and microphone as
well as other shared USB devices to the KVM switch.
Step 3.

using the DVI-I video cable, USB (Type A-to-Type B)
cable and audio & Mic cables (see the pictures

Step 4
. (
Now your KVM Switch should have been powered-
up….
) Power up the connected computers one by
one. After your computers are powered up, the
keyboard and mouse will be recognized and now you
can begin operating the KVM switch.
And also you should verify the USB device on your USB Hub
Ports are fully functioning after installation of its driver on both
connected PCs.
If you need to connect to the analog video source (HDB15), you
might need to use a HDB-DVI adapter to facilitate connection with the
KVM switch.
Easy Operation
There are three methods to control your KVM Switch for PC,
USB hub port as well as audio/mic channel selection: using
the
front-panel push buttons,
a
hotkey sequence, or the
Switcher Software.
Front-panel buttons
The front-panel buttons let you have direct control over KVM
switch operation and channel switching. Simply press the
PC
button for PC port switching (and if binding is enabled
between PC / USB hub port control / audio&mic switching,
they will be jointly selected at the same time). If you want to
enable the binding of PC / Hub port control / Audio&Mic
switching, use the hotkey sequences.
See Quick Reference Sheet
Keyboard hotkey
A keyboard hotkey sequence consists of at least three specific
keystrokes:
See Quick Reference Sheet
Hotkey sequence = [ScrLk]
*
+ [ScrLk]
*
+
Command key(s)
* User-definable = SCROLL LOCK, CAPS, ESC, F12 or NUM LOCK
Hotkey preceding sequence configuration:
For users who want to
use a preceding sequence other than two consecutive Scroll Locks,
there is also one convenient way to configure it.
(1)
Hit ScrollLock +
ScrollLock + H, then two beeps will signal readiness for new
preceding sequence selection [or Press and hold down the last front-
panel button (Button 2) until you hear two beeps, then release the
button.]
(2)
Select and press the key you would like to use as your
preceding sequence (
SCROLL LOCK
,
CAPS
,
ESC
,
F12 or NUM
LOCK
keys are available for selection) and you’ll hear a beep for
selection confirmation. Now you can use the new preceding sequence
to execute your hotkey commands.
Each keystroke within a hotkey sequence should be pressed
within 2 seconds. Otherwise, the hotkey sequence will not be
validated.
For detailed Hotkey sequences and their corresponding functional
commands, please refer to the Quick reference sheet.
Switcher Software
The KVM switcher software provides Windows version and
Mac version. Before you can operate the KVM switch with the
Switcher Software, you have to install it to the connected
computers. Please refer to the following sections for details of
software installation and operation.
Install the Switcher Software
Note that the Switcher Software provides an alternative way for
KVM operation in addition to the original hardware hotkeys. Thus,
if you are satisfied with the hardware hotkeys, you don’t
necessarily have to install the software client.
Step 1.
Insert the companion CD-ROM into your CD-ROM
drive, and the Autorun screen will pop up (If the
Autorun feature has not been enabled on your
computer. Just find the Autorun.exe on the CD-ROM
and double-click it to start).
Step 2.
Click the “Software Installation for Window” to start
installation. Follow the instructions to completion. If
the instillation is complete, you will see a KVM
Switcher icon appear on the system tray of your
desktop. Right-click to evoke the operation menu and
double-click to evoke the configuration box. For Mac
User, you should find the Mac switcher software (with
a file extension of .pkg or .zip) and install it on your
Mac.
The Windows switcher software is recommended for use on
Windows 98 SE or later.
And the Mac switcher Software is
recommended for use on Mac OS 10.4 [Tiger] and later.

No live connection detected
Current active PC channel is on port 1
Current active PC channel is on port 2
The KVM Switcher Software supports the Windows operating
systems. For other OS platforms such as Linux, you can still use the
keyboard hotkey -
ScrLk + ScrLK
+ (x), x = port number, to switch PC.
Some older computers with USB interface might need to
manually enable the USB option in the BIOS settings before you
can use any USB devices. If your USB interface does not work,
please check the USB option in the BIOS.
If you use Windows 95/98/SE or Mac OS and has not yet
installed a USB mouse on your computer, there might be an error
message telling you that mouse is not detected and prompting
you to decide whether to ignore the same message in the future,
and yet you will find there is no mouse movement to disable this
message….So it is suggested that you should installed your USB
mouse on your computer first, before connecting it to this KVM
Switch.
