is inhabited with legacy computers with only PS/2 interfaces and yet with
some newer computers equipped with only USB interfaces. You can

secured and centralized management.

electromagnetic interference commonly seen in lab or factory floor
environment. It also features a
hot-plugging
capability [for the PS/2
interface] that allows you to plug off and on the KVM cablings without
powering down a whole rack of servers, especially convenient when you
are working on a sever rack. With our highly reliable and quality product,
user can enjoy countless benefits from using it.
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.

whenever is needed to enhance compatibility or functionality. Thus, your
investment on this KVM Switch is further ensured and its life-time value
just maximized!

the KVM switch and your computers, boot them up in correct sequence
and you can start to operate immediately!
For a quick start on installation and operation, please follow the
instructions below.
Out-of-the-box Installation

If yo u are using o nly w in do w PCs
:
fo r the first-tim e
installatio n, yo u do n’t even n eed to po w er do w n all the
co m puters that are go ing to be co nn ected to the KVM Switch …..
The hot-pluggability of this KVM Switch allows “hot-plugging” of the
KVM cables while the computer is powered on, and your mouse will stay
alive throughout. It is especially convenient when you have to change or
rearrange the KVM cablings of your computers while still want to keep
the computers working.
If you are using any Lin ux PCs
: you might possibly experience
a lock on mouse if hot-plugging it to the KVM switch (since Linux is not
a PnP OS somehow)… If your mouse gets locked, you can try to use the
mouse reset hotkeys (see the
Quick Refer ence Sheet
) to bring it back
to normal. Another alternative is to turn the Linux PC off before
connecting it to the KVM Switch.
Step 1.
Connect the shared USB or PS/2 mouse, keyboard and monitor
to the console port connectors on the backpanel of your KVM
Switch.
Note that since the KVM Switch is powered through the USB or
PS/ 2 interface, it is powered on immediately when connected to the USB
or PS/ 2 keyboard/ mouse port of your PC (nonetheless even when the PC
being in powered off state, the USB or PS/ 2 interface is still live with
electricity).
Step 2.
Just connect your USB-enabled [PS/2-enabled] computers (
no
matter they are powered on or off!
) to the PC ports at the
backpanel of the KVM Switch, using our special 3-in-1 USB [or
PS/2] KVM combo cables.
Step 3.
If your computer is still not powered up, then power them up.
Once the computers are powered up (or they are already
powered on before connecting to KVM Switch), you can
manage all of them through the local console of your KVM
Switch.
If you experience mouse lock on any of your computer,
Yo u can
use
the mouse reset hotkey sequence to regain the mouse control
(see
the
Quick Reference Sh eet
).
Easy Operation
There are two methods to select a specific computer, using a
front-panel
push button
or a
hotkey sequence.
Front-panel push buttons
The front-panel buttons let you have direct control over KVM switch
operation and channel switching. Simply press a button to switch to its
corresponding channel.

there is also one convenient way to configure it.
(1)

Scro H, then two beeps will signal readiness for new preceding
sequence selection [or Press and hold down the last front-panel button
(Button 4, 8 or 16) until you hear two beeps, release the button.]

Now you can use the new preceding sequence to execute your hotkey
commands.

pressed within 2 seconds and the following command key(s) should also
be pressed within 2 seconds in likewise manner. Otherwise, the hotkey
sequence will not be validated.
