----------------- Introduction
Overview
The Claxan Switch CL-KVM-5002, CL-KVM-5004,
CL-KVM-5002A, CL-KVM-5004A, CL-KVM-UMH-2,
CL-KVM-UMH-4, CL-KVM-UMH-2A, and CL-KVM-UMH-4A
are computer switches that allow access to two or four IBM
compatible computers respectively from one PS/2 (or USB)
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 and the Claxan Switch is
independent of the computer operating system.
Ready to run right out of the box, this Kit comes with
everything you need - a switch and complete cable sets, just
hook them up andgo. By allowing one console to manage all
your computers, the Claxan Switch eliminates the expense
for extra consoles, the spaces for extra peripherals and the
time hopping around for accessing different computers.
The audio function equipped CL-KVM-5002A /
CL-KVM-UMH-2A allow one microphone and speaker to be
shared by two computers and the CL-KVM-5004A /
CL-KVM-UMH-4A allow four.

Should you encounter any keyboard or mouse problem,
press and hold down the push-button for 3 seconds to
initialize the keyboard and mouse.
Hot-key commands
Hot-key command is a short keyboard sequence to select a
computer or to activate computer scanning. Claxan Switch
interprets keystrokes for hot-keys all the time. A hot-key
sequence starts with two left Ctrl keystrokes followed by one
keystroke.
To select a computer:
left Ctrl + left Ctrl + 1
Selects the computer at PC 1.
left Ctrl + left Ctrl + 2
Selects the computer at PC 2.
left Ctrl + left Ctrl + 3
Selects the computer at PC 3 (for
CL-KVM-5004,CL-KVM-5004A,
CL-KVM-UMH-4, and CL-KVM-UMH-4A
only).

14
left Ctrl + left Ctrl + 4
Selects the computer at PC 4 (for
CL-KVM-5004,CL-KVM-5004A
CL-KVM-UMH-4 and CL-KVM-UMH-4A
only).
NOTE: Do not use the keypad at the right side of the
keyboard for hot key commands.
To start Auto Scan, automatically scans all ports
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. Keyboard and mouse are both operational
during Auto Scan. When it detects any keyboard or
mouse activity, it suspends Auto Scan until the activity
stops; it then resumes with the next computer in
sequence. The length of the Auto Scan interval (Scan
Rate) is adjustable, see below. LED flashes during
Auto Scan for 5004, 5004A, UMH-4, UMH-4A only.
Manual Scan enables you to manually switch back
and forth between 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. LED flashes during Manual
Scan for 5004, 5004A, UMH-4 and UMH-4A only.

15
To adjust Scan Rate this sets the duration before
switching to the next computer in Auto Scan:
left Ctrl + left Ctrl + F3
There are four options: 3, 8, 15 and 30 seconds
.
NOTE: Scan Rate is set to default of 3 seconds after
Claxan Switch loses power, i.e., all connected
computers are turned off.
To adjust keyboard typematic rate (characters/sec),
this setting over-rides that of BIOS and any operating
system:
left Ctrl + left Ctrl + F4
There are four options: 10, 15, 20 and 30
characters/sec.
NOTE: The keyboard typematic Rate is set to default
of 10 characters/sec when Claxan Switch loses all
power sources, i.e., all connected computers are
turned off.

Audio Function
The multimedia module can be LINKed to the back of
CL-KVM-5002A, CL-KVM-5004A, CL-KVM-UMH-2A, and
CL-KVM-UMH-4A for selecting microphone and stereo
speaker signals. The audio signal selection follows computer
selection. It is useful if you want to listen to a particular
computer's audio signal. You can also broadcast audio signal
to a particular computer or all computers connected.
