----------------- Introduction
Overview
The KVM Switch SW0202C is a computer switch that
allows access to two IBM compatible computers from
one keyboard, mouse and monitor. Switching between
computers is as easy as pressing the push button or
entering hot-key commands from your keyboard. There
is no interface card and software to install. The
powerful KVM Switch is independent of the computer
operatingsystem,allowing the attached computers to run
different applications. The space-saving design enables
you to connect all the cables to the back of the
SW0202C taking the least amount of space on your desk.
It is a valuable tool for your computer management.
Automatic Mouse Conversion
This technology enables you to connect computers with
either PS/2 or serial mouse ports to the KVM Switch, and
control both computers from one PS/2 mouse. The
KVM Switch automatically identifies the mouse and
switches to proper mouse protocol.

-----------------Installation
Console Connection
Turn your computers off. Connect a PS/2 keyboard and
a PS/2 mouse to the mini-DIN-6 ports of the C
(CONSOLE) marked with Kand Mrespectively. Then
connect your VGA monitor cable directly to the
HD-DB-15 port ofCas shown in figure 1.
Figure 1:CONSOLE Connection
The monitor connected to theHD-DB-15 VGA port of the
Cmust be capable of synchronizing with the computer's
video signal. If you are uncertain about the monitor type,
please consult the monitor user's manual.
The KVM Switch consumes negligible power and is
designed to run reliably without external power adapter.

Computers Connection
Now you want to connect two computers to the KVM
Switch. Use a male-to-male Mini-DIN-6 cable to
connect from the first PC’s keyboard port to the
corresponding K1 port; and, use another male-to-male
Mini-DIN-6 cable from the PC’s mouse port to the M1
port. Then, connect your computer’s VGA port to the
HD-DB-15 port of the KVM Switch as shown in figure 2.
Follow the same procedures for the second computer
using K2 and M2 port.
Figure 2:COMPUTER Connection
If your computer uses serial mouse, a mouse adapter
should be connected to the computer’s mouse port as
shown in figure 3. (Note: use only the mouse adapter
comes with the kit)
-5-
Figure 3: Adapter and serial mouse connection
NOTE: 1. There is no serial mouse for theC(CONSOLE),
just a PS/2 mouse. The KVM Switch's
automatic mouse conversion system allows you
to connect computers using serial mouse and
control the computers fromone PS/2 mouse.
2. Be ware that the mouse adapter can only be
used on the PC side. Attempting to use it at the
C(CONSOLE) side will not work.
3. If your PC uses an AT style keyboard, you will
need an AT-to-PS/2 keyboard adapter, DIN-5
male to mini-DIN-6 female, at PC side in order to
plug the cable to the SW0202C.

-6-
Initial Power-up
Make sure all computers and KVM Switch are
powered down during installation. After connection,
you just power up the computers; the KVM Switch
will get enough power to operate from the computers.
This procedure ensures the KVM Switch receive
computer settings correctly when computer boots.
Therefore, the KVM Switch generates correct responses
and allows both computers to boot successfully without
user intervention. Should you decide to expand the
system in the future or to replace failed devices, you may
hot plug any additional power-downed computer and
KVM Switch to the system.

----------------- Operations
Front Panel operation
You may switch to a different computer by pressing the
front panel push-button directly or by issuing hot-key
commands. The front-panel red indicator changes to
reflect the computer port selected.The indicator flashes
while in either Auto Scan or Manual Scan mode.
Hot-key commands
Hot-key command is a short keyboard sequence to
select a computer, to activate computer scan, etc. The
KVM Switch interprets keystrokes for hot-keys all the
time. A hot-key sequence starts with two left Ctrl
keystrokes followed by one or two more keystrokes. A
built-in buzzer generates ahigh-pitch beep for correct
hot-key command; otherwise, one low-pitch beep for
error and the bad key sequence will not be forwarded to
the selected computer.
=To select a computer:
left Ctrl+ left Ctrl+ 1
Selects the computer at port 1.
left Ctrl+ left Ctrl+ 2
Selects the computer at port 2
Do not use the keypad at the right of the
keyboard.
=To start Auto Scan, automatically scan power-

-8-
on computers one by one at a fixed interval:
left Ctrl+ left Ctrl+ F 1
To abort the Auto Scan mode, press the left Ctrl
key twice. When Auto Scan detects any keyboard
or mouse activity, it suspends the scanning till
activity stops; it then resumes with the next
computer in sequence. The length of the Auto
Scan interval (Scan Rate) is adjustable, see
below.
=Manual Scan enables you to manually switch
back and forth betweenpower-on computers.
left Ctrl+ left Ctrl+ F2
Press ↑or ↓to select the previous or the next
computer in sequence. And, press any other
key to abort the Manual Scan.
=To adjust Scan Rate which sets the duration
before switching to the next computer in Auto
Scan:left Ctrl+ left Ctrl+ F3
The KVM Switch generates 1 to 4 beeps
indicating scan interval of 3, 8, 15 and 30
seconds respectively.
=To adjust keyboard typematic rate
(characters/sec), this setting over-rides that of
BIOS and any operating system:
left Ctrl+ left Ctrl+ F4
The KVM Switch generates 1 to 4 beeps
corresponding to 10, 15, 20 and 30
characters/sec respectively.
