Introduction
The
LKV-S02ASK/LKV-S04ASK
is a 2/4-port Slim
Palmtop PS/2 KVM Switch with the audio and microphone 
switching function. It allows you to access, control, boot and 
reboot multiple PS/2-enabled computers using only one keyboard, 
video, mouse, and one speaker set and one microphone. It also 
offers user-programmable simultaneous/independent switching of 
PC channel and Audio/Mic channel for flexible multimedia 
application with KVM switching. For users who might need to 
use a hotkey preceding sequence other than two scroll locks, we 
also offer five key alternatives for free configuration. 
 
Before you install
 
The default setting of the 
LKV-S02ASK/LKV-S04ASK
is
appropriate for most systems. The KVM Switch is a Plug-and-
Play device for installation. In fact, you do not need to configure 
the KVM Switch before installation.  
 
For the first time installation of the KVM Switch, please follow the 
instructions below for correct setup sequence: 
The correct setup sequence is ……
(1) Connect the shared keyboard, monitor and mouse and
the speaker set and the microphone to the KVM Switch 
first, and then connect your computers. 
(2) Power up your connected computers… 
Since the KVM Switch receives power from the computer’s PS/2 interface, 
it is powered up when you connect the KVM Switch to a PC. 
 
Out-of-the-box Installation
Take the KVM Switch out of the box and begin installation….
DO NOT TRY to connect the KVM Switch to the computers while
the computers are still in powered-on states. Otherwise, the computer 
will have difficulty recognizing your shared keyboard and mouse. 
 
Step 1. Make sure all the computers that are to be connected to 
the 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 PS/2 keyboard, mouse, monitor,
speaker set and microphone to the KVM switch.
Step 3. Connect each of your computers to the KVM switch,
using appropriate KVM & Audio/Mic cables.

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. 
Easy Operation
 
There are two methods to control your KVM Switch for PC 
switching: using the face-panel push button or a hotkey 
sequence. For audio/mic switching, use the hotkey command. 
See
Quick Reference Sheet
 
Face-panel buttons 
 
The face-panel buttons allows you a direct control over PC port 
switching. Simply press the button to switch PC port. By default, 
PC port switching and Audio/Mic port switching are bound 
together (both will be switched simultaneously). 
If you want to enable the binding of PC and audio/mic port 
switching, use the hotkey sequence, ScrLk +ScrLk + Q. To 
disable the binding again, just hit ScrLk +ScrLk + W.
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: 
 
Step 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 or Button 4) until 
you hear two beeps, and then release the button.] 
 
Step 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. 
Another way to activate the Hotkey preceding sequence
configuration is to press the last front-panel button (button 2/button 4) 
for over 3 seconds to set the KVM switch into hotkey configuration mode. 
Then you select and press the key that you’ll choose as the preceding 
sequence. 
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.
