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. Connect the shared USB keyboard, mouse, two

monitors and the speaker system and microphone as

well as other shared USB devices to the KVM switch.

Step 3. Connect each of your computers to the KVM switch,

using the DVI-I video cable, USB (Type A-to-Type B)

cable and audio & Mic cables (see the pictures

below).

DVI - I Video USB cable Audio&Mic

Cable (Type A-to-Type B)

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, ahotkey 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 OS10.4 [Tiger] and later.

Windows Mac OS

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.

KVM Switcher Operation Reference

Switch to PC x by Operation Menu

Right-click the KVM Switcher icon to evoke the operation

menu, then select whichever PC that is available for switching.

Once you select a PC channel, it will immediately switch to

that PC. Note that the unconnected port(s) or the active port

will be grayed-out and hence non-selectable.

Switch to PC x by Keyboard Hotkeys

Troubleshooting

Q. My monitor will show off some aberrations (such as speckles,

stripes, shuddering, smearing or ghosting, and even sync loss,

etc) when the resolution goes up to over 1280 x 1024 (or starting

from 1024 x 768 up). What has caused the problem?

A: Sometimes, video artifacts such as speckles, stripes, shuddering,

and even sync loss, etc. might arise due to an incompatibility between

Dual Link DVI monitor display mode and Single Link video card

display output. To prevent these video problems from happening,

make sure you use a Single Link display mode on your

LCD/monitor Display (no matter your LCD monitor is a Dual Link

or Single Link one) and a Single Link video card on any of the

connected computers. Note that this Single Link KVM Switch is

designed primarily for use with Single Link display cards and Single

Link monitors.
