Out-of-Box Installation

Take the Support CD-ROM and KVM Switch out of the box and
follow the steps below for installation….

Step 1. Insert the Support CD-ROM into your CD-ROM drive,

and the installation interface 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. For Windows/Mac: Just click the “Software Installation

for Windows” to start Windows switcher software
installation. To install Mac version, please copy the file
(*.pkg format) to the local hard disk and install it from
there. Follow the instructions to completion. If the
installation is complete, you will see a KVM Switcher
icon on the system tray of your desktop. Right-click to
evoke the operation menu and double-click to evoke
configuration box. For operation details of the KVM
Switcher software, please refer to the following sections.

Windows Mac OS

No live connection detected

Current active computer channel is on port 1

Current active computer channel is on port 2

The Mac version of the KVM Switcher software supports only Mac

OS 10.4 (Tiger) and later. Earlier version of the Mac OS might
or might not work well with it.

The KVM Switcher Software supports both the Windows and Mac OS

operating systems. For other OS platforms such as Linux , you
can still use the universal keyboard hotkey - ScrLk + ScrLK - to
switch computer. However, this switching hotkey is not
available on non-computer platform such as Mac OS.

Step 3. Connect a set of the fixed KVM/Audio&Mic cables to a

computer’s connectors. Connect another set of cables
to another computer. Now you can operate the KVM
Switch immediately.

Some older computers with USB interface might need to manually
enable the USB option in the system BIOS settings before you can
use any USB devices. If your USB interface does not work, please
check the USB option status in the system BIOS.

If you 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 found 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.

Ways for KVM Switch Operation

There are three methods to control your KVM Switch for
computer and audio/mic channel selection: using (1) the

Quick Installation Guide Applicable model: LDV-302ARC 2-port DVI USB KVM w/ Audio&Mic Plus QuickSwitch Button for wired remote control

Rev. 1.0 Copyright© All rights reserved.

QuickSwitch Button (a wired remote control), (2) a hotkey
sequence or (3) the KVM Switcher Software.

QuickSwitch button (a wired remote control)

The QuickSwitch button is a wired remote control that allows
you a direct switching control. Simply press the button to
toggle between the two computers.

You can use the QuickSwitch button to switch to an empty port that
is not connected with any computer. Normally, if you use keyboard
hotkey or the KVM Switcher software, you will not be able to switch to an
empty port (and audio/mic channel, if binding is enabled). By default, PC
port switching and audio/mic port switching are bound together, unless
you specify the audio to be fixed a specific port.

Keyboard hotkeys

User-definable hotkeys for computer selection:

Hotkey sequence = Ctrl + Alt + [command key]*

* Please refer to next section for keys that are qualified to
be used as a command key

Universal hotkey for computer toggle-switching:

Both the universal hotkey, ScrLk + ScrLk and the user-definable
hotkey, Ctrl + Alt + [command key] WILL NOT allow you to switch to an
empty port that is not connected with any computer. To force your KVM
to switch to an empty port, just press the QuickSwitch button to switch.

Universal Hotkey sequence = ScrLk + ScrLk

* For other operating systems on computer such as Linux, you
can still use this special hotkey to facilitate computer
switching. This special hotkey is not available for Mac.
HOWEVER, you can press QuickSwitch button to switch in any
case.

Each keystroke within a hotkey sequence should be pressed within 2

seconds. Otherwise, the hotkey sequence will not be validated.

After port switching, you have to wait till the KVM Switch icon
shows forth the target port before you can perform next switching again.
The KVM Switcher icon could be found on the system tray/task bar of
your Windows/ Mac OS desktop after its installation.

All the hotkeys are only functional after your computers are booting
into the OS. If you want to switch computer in the BIOS/preboot stage,
press the QuickSwitch button to switch.

KVM Switcher Software (Windows & Mac platform)

In addition to computer switching, the KVM Switcher
Software also allows you more advanced functions such as
