Overview
One-Console KVM Switches
The KVM Switch allows you to access multiple computers from
keyboard, mouse and monitor. There is no interface card or
software to configure. Installation is as easy as connecting cables
between the KVM Switch and your computers. Operation is as
simple as pressing push button, entering hot-key command and
navigating through the user-friendly on-screen menu (available on
models with OSD support). Depending on the model you have, it
switches up to 4 (KNV104), 8 (KNV108) or 16 (KNV116D)
IBM-compatible computers. The KVM Switch is independent of the
computer operating system.
Two-Console KVM Switches
The advanced multi-access KVM Switches enable you to control
multiple computers from
with two keyboards, mice and monitors. KNV2108D controls 8
computers and KNV2116D controls 16 computers.

For KVM Switches with built-in OSD control, you can name your
computers, switch to a computer from a list, configure settings with
easy-to-use menus, view the name of the selected computer
on-screen with programmable time interval. The OSD menu
displays the system status throughout operation.

Automatic Mouse Conversion
The KVM Switch enables you to connect computers with PS/2 or
serial mouse ports (using adapters supplied with each KVM Switch)
and control the computers from one PS/2 mouse. The KVM Switch
automatically identifies the mouse and adapts proper mouse
protocol.
High Video Quality
The KVM Switch supports VGA resolution up to 1920 x 1440 without
any degradation. Advanced VGA circuit design guarantees smooth
and flicker-free switching from one computer to the other with
distance up to 100ft (30M)* at both Console and PC sides.

Configurations
The KVM Switch has several models each supporting a different
number of computers. For applications with a large number of
computers, KVM Switches can be cascaded in a master/slave
configuration to support even more computers.
Single KVM Sw itch Configuration

respectively, as shown in figure 4.
For computers using serial mouse, connect the DB-9 to mini-DIN-6

Multimedia Module
An optional multimedia A/V module (MAV108) is used to select
microphone, speaker and monitor signals from one out of eight or 16
computers. The A/V module is connected to the
rear panel via an mini-DIN-8 connector. When a computer is
selected, the microphone signal is directed to that computer, speaker
and monitor signal source from the same computer.
As an OSD option, the A/V module may select a computer different
from that of the KVM system. There are two options in
function (<F4>:More\Audio Stick). When set to 'On', A/V module
selection follows computer selection. When set to '
selection stops following computer selection. It is useful if you want
to listen to one particular computer's audio signal while selecting
other computers during operation.
With extra VGA ports, the A/V module enables you to view multiple
monitors from one PC at the same time. Now you can extend your
Windows desktop for all your computers and switch accordingly.

Hot-key commands
Hot-key command is a short keyboard sequence to select a computer,
to activate computer scan, etc. The KVM Switch interprets
keystrokes for hot-keys all the time. A hot-key sequence starts with
two left <CTRL> keystrokes followed by one or two more keystrokes.
A built-in buzzer generates a high-pitch beep for correct hot-key
command; otherwise, one low-pitch beep for error and the bad key
sequence will not be forwarded to the selected computer.
