3.1 System Requirements
-One available USB port and one available VGA port
-Windows 98 or later, Mac OS9/OSX, Solaris 8 (SUN BLADE 100), Linux
Kernel 2.3 or later
3.2 Hardware Installation
1. Make sure that the USB port of your computer is enabled and working
properly.
2. Connect the USB cable Type-A end to the USB port of your computer, and the
USB cable Type-B end to any available port on the KVM Switch.
3. Connect the VGA male-to-female cable between the video port of your
computer and video port that corresponds to the USB port you selected in step 2.
4. Repeat steps 1-3 for any other computers you are connecting up. Up to 4
computers can be connected at the same time.
5. Plug the power adaptor cable into the KVM switch.
3.3 Powering Up The Systems
Boot the computers. For best performance from your display, make sure to select
a port first, and let that PC completely boot before switching to another port. Sun
Micro users; this is required. For other users, this is highly recommended.
3.4 Hot Plugging
The KVM switch supports USB plug & play technology. USB devices can be
added and removed to the front panel hub at any time without the need to
shutdown.
Note: Windows 98 users will need to install drivers. See Appendix A.
If you
are using a USB keyboard and/or mouse as your primary means of input, you
will need to enable the Auto Switch function. See page 12 for details.

3.5 Using the OSD program; examples
a. “No PCs Found” means that the KVM Switch cannot acquire the PC status.
This is either because the PC did not connect or is powered off.
The large red “4” and small green “2” mean that two PCs are connected to Port 1
and Port 4 of your KVM Switch respectively, and you have switched to Port 4
already. So the OSD program will display “PC 4 On” underneath. You can click
the “2” to switch to this available host.

The large red “4” and small green “1, 2, 3” means that four PCs are connected to
Port 1 and Port 4 of your KVM Switch respectively, and you have switched to
Port 4 already. So the OSD program displays a “PC 4 On” underneath. You can
click on “1, 2 or 3” to switch to a certain available host.
1) When you click the “Hide” button, the OSD program window will hide in the
Taskbar.
2) When you click on the “Close” button, the OSD program will exit.
3) If the OSD program is hidden in the Taskbar, you can use the right mouse
button to show or exit program.

4. O eration
The KVM Switch supports three methods to switch between computers:
Pushbutton, Hot Keys, and OSD. Due to the refresh of the video and
re-synchronization of the mouse and keyboard signal, it can take up to 3 seconds
before control is re-established after switching to ensure proper signal
synchronization.
Note for users with connected USB devices (other than keyboard/mouse):
The drivers for most USB devices (Mass Storage device, CCD Cameras,
Scanners, Card Reader, Printers, e.g.) require the device to be disabled before
you disconnect the device. Follow the “Safely Remove” process provided in
Windows before you disconnect the device to avoid system freezes or other
problems. When you switch computers via the KVM, it is the equivalent of
disconnecting the device. Therefore, if you have peripheral devices (other than a
second keyboard and mouse) connected to these ports, you must be sure to shut
down or safely remove the USB driver for them before switching computers.
1. Manual Switch by pushbutton:
You can switch to any other available active USB host connection by simply
push the appropriate switch button on the KVM Switch. The LED will be lit to
indicate which port is currently selected.
2. Two Step Hot Key Switch by PS/2 keyboard:
You can switch to any available PC by entering a two step Hot Keys sequence
directly from the PS/2 keyboard. To send commands to the KVM Switch, [Scroll]
must be pressed twice (Step 1). Then you can press [1] to [4] (Step 2) to switch
between ports.
Note: Hot keys are supported by PS/2 Keyboard only. USB keyboard users must
use manual switch method or OSD.
*After invoking the Hot Key function with the [Scroll] , [Scroll] , you must press
the corresponding final command (Step 2) within 3 seconds for each key press.
(The Scroll Lock LED on the keyboard will start blinking and wait for the final
command. After completing the hot key sequence or 3 seconds have elapsed, the
keyboard LED will revert back to its original state.)

required mode for a USB keyboard or mouse to work with all connected
computers.
There are two ways to turn the HUB Auto-Switch mode ON :
A). By hot key via PS/2 keyboard; [Scroll+Scroll][H] : please reference the
hotkey table in page 11.
B). Press and hold any of the PC port selector buttons continually for 2 seconds
when the Auto-Switch mode is OFF. The Auto-Switch LED will turn ON.
