|A KVM (Keyboard, Video and
Mouse) switch is a control unit that allows centralized
control of multiple computers from a single console.
Setting up a KVM installation is simply a matter
of using specialized cables to connect the keyboard,
video, and mouse ports on the computers to the KVM
ports on the switch. In a large-scale centralized
server room, huge savings in terms of equipment
space, and energy expenses can be obtained by deploying
a KVM Switch installation.
Early KVM devices
consisted of simple switch boxes to link keyboard,
video, and mouse ports using serial, D-Sub 15
or and AT ports. Since then the method of linking
multiple KVM systems has been constantly improving.
Modern implementations use PS/2 and USB interfaces,
and even include DVI video and stereo audio transmissions.
The latest advancements include KVM-over-IP to
which allows users to manage their installations
from remote location over the Internet using a
One of the most distinguished examples in ATEN's
advanced KVM switch lineup is the LCD KVM Switch.
To understand its benefits, let's first look at
the two major drawbacks found with conventional
KVM switches: 1) Although a single console can
control multiple computers, the console that interfaces
with the switch exists separately from the switch
-- taking up server room space and resources; and
2) If two operators need access to the system
at the same time, one of them will have to wait
-- diminishing the installation's efficiency.
With an LCD KVM switch, however, the KVM console
is built right into the switch. Since the monitor
flips down and the unit slides back out of the
way, it fits perfectly in a 1 U system rack, with
no waste of space.

ATEN LCD KVM Switches offer the perfect solution
for enterprises that want to control server room
costs, make efficient use of space, and modernize
their server room capability. The benefits of
an LCD KVM Switch can be demonstrated by looking
at two of our most popular models: the ALTUSEN
and ALTUSEN KL3116,
Hideaway™ LCD KVM Switches.
Looking at the ALTUSEN KL1116
Dual slide Hideaway™ LCD KVM Switch, we
can see that when it is pulled out from the rack,
its top cover rotates up to reveal a monitor built
in to its top cover, and a keyboard and touch
pad underneath. When the LCD monitor is closed,
the entire unit can slide back into the rack taking
up only 1U of rack height -- a significant savings
in rack space over a conventional console arrangement
since the space above and below the unit is available
for other devices.
LCD monitor can either be 15 or 17 inches and
contains ports for connecting up to 16 computers.
Up to 31 additional units can be daisy chained,
to enable access and control of up to 512 computers
-- all from the single built-in LCD console.
also incorporates ports that permit users to attach
an external console -- offering the ability to
access the installation from a remote location
as well as at the rack. In addition, if an installation
comprises numerous computers, two operators may
want access at the same time. By supporting a
second console, the KL1116
can easily provide for control of the installation
from both locations on a one-at-a-time basis.
Key functions of the switch are shown in the following
||All-in-one design -- Integrated
LCD KVM console in a dual slide (LCD monitor
component can slide independently of the keyboard/touchpad
component) Hideaway™ configuration.
||Dual slide housing is slightly less than
1U - with top and bottom clearance for smooth
operation in a 1U high system rack.
||Space-saving technology -- Supports 2 consoles
(one bus) to manage up to 16 computers.
||Dual console design (one built-in; the other
externally attached) -- allows access and management
by 2 users (one at a time) with control easily
switched via a hotkey.
||Dedicated keyboard keys to instantly invoke
Hotkey and OSD modes.
||No software required - convenient computer
selection via mouse-driven intuitive OSD (On
Screen Display) menus, Hotkeys and pushbutton
||Supports hot-plugging -- add or remove computers
without having to power down the switch.
||The OSD port list automatically expands
and incorporates a new computer when it is
added to the installation.
||DDC Emulation for the LCD Monitor - VGA
settings of the connected computers are automatically
adjusted for optimal output to the LCD Monitor.
||Supports Windows, Linux, Unix, Netware,
AIX (RS6000), DOS 6.2 and higher.
The new ALTUSEN KL3116
Hideaway™ LCD KVMP Switch is similar in
features to the KL1116.
In addition, the KVM connectors have been changed
to a combined PS/2 and USB interface. Additional
USB ports are provided for sharing USB devices
connected to the KL3116
among the computers on the installation. A few
changes have been made to the operation interface,
providing more options for the system manager:
LEDs to indicate which computer currently has
the KVM focus; a Port Up/Port Down button for
quick port switching; a PS/2 mouse port for people
who aren't comfortable with a touchpad; and an
enhanced OSD that provides a tree view for a quick,
easy to grasp display of information concerning
all the computerson the installation. This is
especially helpful for large, daisy chained installations.
All ATEN and ALTUSEN LCD KVM Switches can be
handled by one person. Thanks to the Easy Rack
Mount Kit, it's only a matter of minutes for a
single person to install the switch in a standard
system rack as shown in the photos, below:

The ATEN LCD KVM Switches product line currently
comprises the following products: the ATEN CL-1200,
as well as the advanced ALTUSEN Series KL1116
. The CL-1200 differs from the others in that
it only consists of the LCD module. It does not
contain a KVM switch component. It was designed
for users who already have an ATEN or ALTUSEN
KVM Switch and would like to take advantage of
the Hideaway™ benefits without having the
expense of the KVM module found on the other Hideaway™
With their unique, advanced features, ATEN LCD
KVM switches are the most convenient and efficient
