Overview
One-Console KVM Switches
The KVM Switch allows you to access multiple computers from one
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.

Configurations
Cascade (Master/Slave) Configuration
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 Switch Configuration
Connect a PS/2 keyboard, a PS/2 mouse and a VGA multi-sync
monitor directly to the Master’s CONSOLE port. Then, connect
multiple sets of keyboard, mouse and monitor cables to the “PC x”
ports of the KVM Switch, as shown in figure 1.
Figure 1: A single KVM Switch configuration
You can connect a second level of one or more KVM Switches to “PC
1”~”PC 4” (KNV104) or "PC 1"~”PC 8” ports (KNV108 & KNV116D) of
a Master unit.
Cascade configuration expands system ability
allowing you to select computers connected to the Master or Slaves.
There is only one Master, which has a mouse, a keyboard and a
monitor connected to its CONSOLE port directly operated by a user.
Once connected, KVM Switches automatically configure themselves
to either Master or Slave. Slaves of different models can be mixed
in cascade configuration. [NOTE: Master must have equal or more
PC ports than that of Slaves, i.e., if KNV108 is a master, KNV108 and
KNV104 can be Slaves, but KNV116D can not.]
Figure 2: A cascade KVM Switch configuration
Throughout this manual, Master is the KVM Switch that has a
physical keyboard, mouse and monitor connected to its CONSOLE
port. Slave is a KVM Switch that has its CONSOLE port connected to
a Master's “PC x” port. Slave only exists in cascade configuration.

Device Connection
The monitor connected to the HD-DB-15 VGA port of a Master
CONSOLE must be multisync capable of synchronizing with the
computer's video signal. If you are uncertain about the monitor type,
please consult the monitor user's manual. Connect a PS/2 mouse
and a keyboard to the CONSOLE port marked with a mouse and a
keyboard respectively as shown in figure 3. [NOTE: Only a PS/2
mouse can be connected to the CONSOLE mouse port. The KVM
Switch automatic mouse conversion system allows you to connect
computers using serial mouse and control the computers from one
PS/2 mouse.]

Determine the port address of each computer. For computers using
PS/2 mouse, connect the computer's mouse and keyboard cables to
the KVM Switch connectors marked with a mouse and keyboard
respectively, as shown in figure 4.
Initial Power-Up
Make sure all computers and KVM Switches are powered down
during installation. You must power up the Master KVM Switch
before turning on any other devices.
For single KVM Switch: 1) Apply a power adapter to the
Master. 2) Turn on computers.
For cascade: 1) Apply a power adapter to the Master.
2) Apply power adapters to all Slaves.
3) Turn on
computers.
Note: You may hot plug additional powered-down computer and
Slave without turning any existing KVM Switch or computer off after
initial power up.
Replace Master Console Devices
Figure 4: Master computer connection
For computers using serial mouse, connect the DB-9 to mini-DIN-6
adapter (supplied with the KVM Switch) to the computer mouse port,
then use PS/2 cables to connect the mouse to KVM Switch, see
figure 5. Connect the computer's monitor cable to the HD-DB-15
VGA connector. Repeat above steps for all remaining computers to
be connected to the KVM Switch.
You can replace a faulty keyboard or mouse of the Master
CONSOLE port at any time without powering down the Master, as
long as your computers are booted with proper device driver for the
new device. Should you encounter any difficulty, just activate K/M
RESET by holding both front-panel ‘1’ and ‘2’ push buttons down for
2 seconds.
Adhesive Rubber Foot
For desk-top operation, you may stick the four round rubber feet
(supplied with the unit) to the bottom of the KVM Switch. NOTE: Do
not use the rubber feet for rack mount operation. Give the rubber
feet a firm press to prevent them from getting loose.

------------------------ Operation
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 LINK port on 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 Audio Stick
function (<F4>:More\Audio Stick). When set to 'On', A/V module
selection follows computer selection. When set to 'Off', A/V module
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.
Front Panel Push Buttons
You may select a computer by pressing the front panel push button
directly, by issuing hot-key commands or by activating the OSD
window (for models with OSD support). The front panel indicator
changes to reflect the computer port selected (red) and whether the
port is connected to a powered computer (green).
The indicator
flashes red when it is in either Auto Scan or Manual Scan mode.
Figure 8: Front panel indictor
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.
Some computers support 'keyboard/mouse power up' function, i.e.,
press certain keys or mouse buttons to startup the computers. Their
corresponding green front indicators lit all the time even if the
computers are 'off'.
K/M RESET
K/M RESET solves most problems developed by keyboard, mouse,
device replacement or change of configuration. Press down both
the front-panel number 1 and 2 push buttons for 2 seconds to
re-configure the whole system without turning either the KVM Switch
or any computer off.
AUTO SCAN
The KVM Switch provides an easy to use feature to start Auto
Scanning. You can press down both the front-panel number 7 and 8
buttons for 2 seconds to start Auto Scanning.

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.

--------------- Cascade Configuration
Connection
Before connecting a device (a computer or a Slave) to the Master
under power, you must turn off the device. The Master must have
equal or more 'PC x' ports than that of the Slave, i.e., if KNV108 is
the master, KNV108 and KNV104 can be Slaves, but KNV116D can
not.
The ports labeled "PC 1"~”PC 8” can be connected to either a
computer or a Slave's CONSOLE port, as shown in figure 10. The
ports “PC A"~”PC H” can only be connected to a computer. A
power adapter with DC 9V/500mA output rating must be connected
to the Master.
Figure 11: Cascaded 4-port KVM Switches
Figure 12: Cascaded 8-port KVM Switches
Figure 10: Slave console connection
The maximum number of computers controlled by a master/slave
configuration with all KNV104s is 16 with 4 Slaves and each Slave
connects to 4 computers, see figure 11. For an all KNV108s
configuration, the number is 64 with 8 Slaves and each Slave
connects to 8 computers, see figure 12. For an all KNV116D
configuration, the number is 136, see figure 13. The Master
KNV116D connects to 8 Slaves and 8 computers, and each Slave
connects to 16 computers.

For OSD model:
After connection completes, you should re-activate the
OSD menu to check if the Master recognizes the
Slaves. A triangle mark () is placed to the right of
the port name indicating the port is connected to a
Slave not a computer. A number to the left of the
triangle mark indicates the Slave model, i.e. 8 for
KNV108 or KNV108D.
Change Configuration while Running
Devices at any 'PC x' port can be changed at any time after initial
power-up. If you change any one of the “PC 1” to “PC 8” ports
connection from a computer to a Slave or vice versa, or replace the
devices of a port; the OSD will update this change the next time it is
activated. [NOTE: Any new device, a computer or a Slave, must be
turned off before it is connected to the Master.]

------------------Multi-access KVM Switch
KNV2108D & KNV2116D
Overview
The advanced multi-access KNV2108D and KNV2116D have all the
features of KNV108D and KNV116D respectively. Both models
have two Console ports facilitate you to access multiple computers
from one out of two locations, local and remote. Thanks to the
high-drive circuit design, you may connect high quality cables at
Console and PC sides for up to 100ft (30M), a definite plus for server
room applications. Now you can access all computers either in the
server room when you have to physically access the computers such
as software upgrade, or away from the server room for everyday use.
Connections
Connect two keyboards, mice and monitors to the two CONSOLE
ports. The built-in PS/2 mouse signal translation enables you to
connect PS/2 mice of different type to the CONSOLE ports, i.e., a
generic PS/2 mouse for one CONSOLE and a scroll mouse for
another.
25
------------------------ Appendices
Operation
On power up, the KNV2108D and KNV2116D are in Idle mode
broadcasting VGA signal from the selected computer and detecting
for keyboard and mouse activity. User LEDs (marked with reverse
white A and B) are both red indicating the KVM Switch is not in use.
Specifications:
When keyboard or mouse activity is detected at one CONSOLE, the
KVM Switch immediately disables the other CONSOLE from
accessing the computer. Only one User LED, at the front panel,
remains lit indicating the KVM Switch is under user operation. In
the mean time, keyboard LEDs (Num/Caps/Scroll Lock) of the other
CONSOLE start to flash as its access is denied and the monitor is
blocked from VGA signal for security reason. After the user has
finished his operation for a period of time (i.e., User Timeout), the
multi-access KVM Switch returns to Idle mode. User Timeout has
four options, 5 sec, 30 sec, 60 sec and HOLD. Select HOLD when
you plan to access the KVM Switch for a long time. Pressing the
<Scroll Lock> twice forces the KVM Switch return to Idle mode
immediately regardless of the User Timeout setting.
The User Timeout is available in the OSD menu by pressing the
Function key <F4>, under the sub-menu More. Note: Keyboard
Speed option is not available for multi-access models.
Configuration
To expand the number of computers under control, you may connect
CONSOLE port of another KVM Switch to "PC 1" ~ "PC 8" port.
Refer to the chapter Cascade Configuration for more detail. There
are rules to apply for Master/Slave configuration. When KNV2108D
is a Master, its slave includes KNV104, KNV104D, KNV108 and
KNV108D. When KNV2116D is a Master, its slave includes all the
above and KNV116D. These multi-access KVM Switches already
come with OSD menu, their Slaves do not have to be OSD equipped.
