Introduction
PLANET USB KVM Switches are designed to give you control of
multiple computers using just one keyboard, mouse and VGA
monitor. They provide more table and rack space in addition to
saving the cost of multiple keyboards, mice and monitors. Switch
between computers by just pressing a button on the panel or
predened hot key on connected keyboard. The USB KVM Switch
series are the perfect choice for home, ofce, server farm, or
testing site where there is a need to manage multiple computers
efciently and easily.
PLANET USB KVM Switches utilize advanced microprocessor
emulation to intelligently manage each KVM port. This allows
simultaneous boot-up of all the attached computers. Caps Lock,
Num Lock and Scroll Lock status can also be saved for each
computer. They support VGA, SVGA and MultiSync monitors up to
2048 x 1536 resolutions.
Furthermore, all the PCs that with a USB port can connect to the
USB KVM Switch and controlled by a PS/2 keyboard and mouse.
With build-in 2/4-port USB Hub, you can connect USB devices to
the USB hub and share to the PCs which connected to the USB
KVM Switch. With different switching mode, the USB hub can x to
one PC used or changed when you switch to next PC.

Different motherboard BIOS has different set up procedure. Here
are some examples, which based on some kind of BIOS version,
below for the user reference.
A. AWARD BIOS: To press “Del” key immediately for a
couple of times when powering on PC and you will get
into BIOS set up mode à Select “Advanced” item à
USB Legacy support à Select “AUTO” à Save and quit
BIOS set up.

Usage
Push Button
USB KVM Switch provides one push button. You can select PC port
through it. Pressing the button in series to the destination port as
you want through all the ports.
Keyboard:
There is the connector which PS/2 keyboard can be applied to
this switch.
Mouse:
There is the connector which PS/2 mouse can be applied to this
switch.
Monitor:
There is the connector for connect your monitor to this switch.
LED Indication:
Two colors LED (Orange, Green) is applied to each PC port of USB
KVM Switch. Each PC port LED will show in different color light
based on USB hub is attached to the PC port or not.
1. If the console port and USB hub stay at the same PC
port, the PC port LED is lit in orange color.
2. If the console port and USB hub are located at different
PC ports, the PC port LED connected to the console port
will be lit in orange color and the other PC port con-

12
13
nected to USB hub is lit in green color.
3. When you select one of PC ports and this PC is shut down
or this PC port is disconnected to the PC, the selected
port LED will flash in orange color.
USB Hub Power management:
If you prefer to running KVM-U401 as an USB bus power mode,
this switch draws the power from PC’s USB port.
1. If you use one or two USB hub ports, KVM-U401 is able
to supply enough power for one or two USB devices at-
tached to USB hub port.
2. If you use more than two USB hub ports, KVM-U401
needs minimum two PC’s USB ports power to go normal
operation. It means that there are two PCs which pow-
ered on always connected to this switch to guarantee
working condition and it need consume 500mA from
each of these two PC’s USB port.
3. If there is only one powered on PC connected to this
switch, the power is not enough for using more than two
USB HUB ports that built in KVM-U401.
There are two solutions as follows:
1. Please power on the other PC connected to this switch.
Every time, there are two PCs keeping at power on
mode. So, there are 1000mA power source for KVM-
U401 and 4 Port USB HUB ports. Each USB hub port
(Bus Power mode) can offer 100mA for the USB device.
2. To add one DC 5V, 2.5A power adapter to KVM-U401 or a
DC 5V, 2A power adapter to KVM-U201. The power jack
polarity is center positive.

Troubleshooting
Ensure that all cables are well seated. Label all of cables with the
number for each respective computer to avoid confusion.
IBM PC or Compatible:
ü When I connect WinNT PC to the USB KVM Switch,
WinNT can not detect the USB KVM Switch, what can I
do?
WinNT system doesn’t support USB function, so WinNT
can not detect the USB KVM Switch. And some of the
Win95 system are not support USB function also, if you
want to use Win95 system with USB KVM Switch, please
ensure the version is 95OSR2.1 or above. Then you can
use this Win95 PC to USB KVM Switch.
ü After switch the PC with USB keyboard Hot-Key, the key-
board is disappear. How can I get the keyboard back?
If you are use USB keyboard, this situation is normally.
When you use keyboard Hot-Key to switch PCs, the USB
Hub will not be switched at the same time. So the PC
which you switch to will not detect this USB keyboard. In
this time, you can use select button on USB KVM Switch
to switch again. When you use select button to switch,
the PC port and USB Hub will be switch to next PC at
the same time.
ü Why the keyboard or mouse not working or not compat-
ible with the PC?
Please make sure the keyboard or mouse works when
directly plug in to the computer. If the problem persists,
please try another keyboard or mouse.
ü WHY mouse doesn’t work in Auto Scan mode?
You can press any key on the keyboard or the front

16
17
button on the face plate for returning standard mode
and then use the Keyboard or Mouse again. When KVM
switch is in Auto Scan mode, there are only VGA moni-
tor display and CPU alternately (but the USB hub is not
switched in auto scan mode). After you press any key,
the PC port will be selected at the same time, as you see
the current PC Screen.
ü Why the PC shows a screen to prompt me the PC cannot
detect the keyboard for work?
If you apply PS/2 keyboard to USB KVM Switch’s PS/2
port and are fail in booting PC on account of keyboard
error (There is a keyboard error message exists on the
screen), the PC BIOS (Basic Input Output System) need
be set (please see the hardware installation procedure)
or upgraded to new BIOS for accepting USB to PS/2
conversion. Normally, most of BIOS support, during PC
boots process, to recognize USB to PS/2 keyboard con-
version or USB keyboard.
ü Why my 4D mouse cannot work correctly with this USB
KVM Switch?
For 4D or 5D mouse user, it is recommended to be used
with a USB hub port of USB KVM Switch if the mouse
supported with USB type. Due to USB conversion stan-
dard does not define PS/2 to USB converter for 4D or
5D mouse, these extra user define key will lose function
when the users use the PS/2 port of USB KVM Switch.
ü How long of the VGA connect cable I can use?
The recommended VGA cable distance is 5 meters
maximum without ghosting and degradation. Normally,
the cable length is based on driver capacity of your VGA
card. If you need longer VGA cable, please use VGA ex-
tender to accomplish your applications.
ü Why I cannot use the USB devices which connect to the
USB hub on USB KVM Switch right away when I switch

16
17
from one PC to another?
When you switch USB hub from one PC to another and
there are many USB devices are attached to the PC, it
will take about 5~10 seconds for all USB devices initial-
ization. So, to switch port will take more time than the
switching time of conventional PS/2 KVM Switch.
ü If I use the Japanese Windows with the USB KVM Switch,
how can I make my keyboard work correctly?
When you use Japanese Windows OS with 106 key
keyboard, there are some special keys like “￥” need
106 key driver (Microsoft native driver in OS CD-ROM).
Please follow procedures as below and click the mouse
to add new driver.
