1. FEATURES AND FUNCTIONS
The TK-802R/TK-1602R KVM Switch is a 8-/16-port cascadable PS/2 type KVM
Switch with OSD control. It enables the network administrator to access, control,
boot and reboot multiple connected computers using only one keyboard, video and
mouse.
Remote computer/server management from one keyboard, mouse and video
The TK-802R/TK-1602R KVM Switch is a quality product designed for secure
remote computer/server management on a centralized single admin desk in
corporate, factory as well as in campus computing environment. It features a
console port to connect your shared keyboard, video and mouse, and 8/16 PC ports
to connect to your computers/servers. You can simply place it on desktop or mount
it on a standard 19” rack for more secured and centralized management. This KVM
Switch features a metal enclosure for better shielding against electromagnetic
interference commonly seen in lab or factory floor environment.
Easy Operation by front-panel buttons, keyboard hotkeys and OSD Menu
controls
The KVM Switch can be easily operated using front-panel buttons, keyboard
hotkeys, as well as OSD Menu control. These available control interfaces yield
more convenient and more effective operation over your daily network managing
routines and hence more productivity for network administrator.
Flexible port capacity through multiple daisy-chained KVM switches
In addition to the choice over the 8/16-port capacity of each individual unit, users
can also take advantage of its cascadable function to daisy-chain up to 16 units of
the KVM Switches together. For example, with 16 units of the TK-1602R KVM
Switches cascaded together, the total port capacity could easily be scaled up to 256
computers. You can also vary port capacity by daisy-chaining multiple units in
different combination according to your real needs.
Saving Time, Space and Money with more productivity
The KVM switches offer special advantages saving time, space and money plus a
significant boost over productivity of the network administrative staff. With our KVM
Switches, you eliminate the need for a separate set of peripherals for each of your
computers. With the number of servers running higher than ever in the corporate
milieu, this will amount to a huge saving on money. The KVM users will also
appreciate the neat space on desktop or working bench that is free from multiple
keyboards, videos and mice. On the other hand, the net admin can save lots of
time not to shift around separate sets of keyboard and mouse, just to keep up with
the network management routines. Hence, the KVM Switch could be a tremendous
help in facilitating a better and more efficient work environment for network
administration, and an indispensable productivity tool that will definitely favored by
the tech-savvy people.

1.3.1.1. Front-panel Buttons
Use these front-panel buttons to directly select channels as well as to perform
specific function such as reset or autoscan.
1.3.1.2. Numerical LED Displays and Indicators
The Numerical LED display(s) and LED indicators on the front-panel show forth the
information of your current switch bank number and port status. The current active
switch bank will be shown on the Dual Numerical LED Displays while the Port
Status is each indicated by a set of two Port Status LED indicators - one red and
the other green. The red LED is lit when the computer is connected to the KVM
Switch and feeding power through the PS/2 keyboard and mouse interface. The
green LED is lit when the computer is currently selected as the active channel to be
controlled with the shared keyboard and mouse.
Note that a red-lit LED means only that the specific port is connected and being powered
through its PS/2 interface. It does not indicate whether that connected computer is in powered-on
or powered-off sate.
Note that a green-lit LED means only that the specific port is selected to be the active channel.
It does not indicate whether that connected computer is in powered-on or powered-off sate.

1.3.2.4. Daisy Chain Port
The daisy-chain port is where you can daisy-chain to another switch for cascaded
application of multiple KVM Switch units.
1.4. KVM Switch Technology Overview
The KVM Switch is a hardware-based device that allows you to control multiple
computers/servers using only one Keyboard, Video and Mouse, hence the name of the
KVM Switch.
The distinction between a KVM switch solution and any other software/hardware
measures for the same control purpose is that: the KVM Switch exerts its control and
operation on the connected computers only by the shared keyboard, video and mouse. It is
more efficient and more versatile as being capable of control from BIOS level up to the GUI
applications.
Not only can a KVM switch save you
money
by eliminating the needs for multiple sets of
keyboard, video and mouse, but also save you
space
from desktop, factory floor or office, and
finally it saves you precious
time
that used to be spent in moving around different desktops,
server rooms or even buildings. And the result is huge savings on many aspects plus a
productivity boost.
Since KVM Switch is a hardware device, it offers a transparency of control that will not
interfere with the way a computer can be operated by and interacts with its user. As
compared to other hardware/software solution for remote control, it takes an intrusive agent
that will interfere with certain aspect of the computer or, at best, functions as well but eat up a
considerable system resources or even large share of computing power, not to mention the
extra costs which can be really expensive sometimes as the Enterprise Management Software.
Therefore, the KVM Switch solution is better in this “transparent” sense for server/computer
remote control.
On the other hand, a KVM Switch also offers a complete and more flexile control than other
software/hardware solutions: a KVM Switch offers a total control from BIOS level such as
CMOS setting up to GUI application as well as and other maintenance routines.
So obvious is the advantage of using KVM switch in an environment that requires users to
control more than one computer. We can see the KVM Switch being deployed in many
diverse applications and locations, whether it is SOHO, corporate or factory
environment. And the professionals who use and come to appreciate the convenience and
elegance of the KVM Switch range from SOHO workers, graphic artists, and network
administrators to lab workers, floor supervisors and lab testing personnel, etc.

Chapter 2 Installation
2. INSTALLATION
Before installing the KVM switch, you should run through the following peripheral checklist
to ensure a proper setup of your KVM Switch….
2.1. Checklist before Installation
: Suitable cables to connect the KVM Switch to the keyboard, video and mouse
ports of each of your PC. For each computer connected, you should have PS/2
mouse cable (all male) and PS/2 keyboard cable (all male) and a HDB-15 VGA
cable (all male). A 3-in-1 combo cable is highly recommended for your
convenience. For more information on the cable specifications, look up in the
Appendix A.
: A monitor with a standard D-sub 15-pin VGA/SVGA connector
(HDB-15) that will work when connected directly to each of your PCs.
: A standard PS/2 style keyb oard. If you are using an AT keyboard with a 5
pin connector you should use a standard AT-to-PS/2 keyboard adapter to
connect to the KVM Switch.
: A PS/2 style Microsoft or Logitech compatible mouse or
a Microsoft IntelliMouse® / IntelliMouse Explorer® compatible
mouse
Figure 2-1 The 3-1 combo KVM cable is highly recommended

Chapter 2 Installation
2.2. Mounting the KVM Switch
The KVM Switch can be mounted either on desktop or on a standard 19” rack.
To adapt to different port capacity requirements, you are able to use the KVM
Switch either in single unit configuration or in multiple cascaded application. If you
intend to use multiple cascaded KVM Switches, please jump to the next section.
2.3. Connect Your PCs and Peripherals to
Single KVM Switch
Before connecting any PC or peripherals to your KVM Switch, make sure that the power
adapter is disconnected from your KVM Switch and all PC or peripherals that ar e going to be
attached to the KVM Switch should be turned off. If you did not turn off your PCs while connecting
to the KVM Switch, the shared keyboard and mouse will not be recognized.
Step 1. Make sure your KVM Switch, your PCs and peripherals are all powered off.
If not, turn the power off for the KVM switch, PCs and peripherals.
Step 2. Connect the shared keyboard, PS/2 mouse and monitor to the console
connectors on the rear of the KVM Switch.
Step 3. Connect the power adapter cord to the KVM Switch to power it on.
Step 4. Connect each computer system (still in powered-off state) to the KVM
Switch in turn either with the individual keyboard cable, mouse cable and
video cable, or the 3-in-1 keyboard/video/mouse combination cable for your
convenience, then power on each computer
The KVM Switch has to be turned on and properly connected to your PCs prior to your
booting up any PC. Please follow the correct boot-up sequence. The reason is that: while your PC is
booting up, it has to communicate with your keyboard and mouse and consequently gets response
from them. If your KVM Switch has not been running and connected to your PC, your PC might
have difficulty recognizing your keyboard and mouse, even if you turn on the KVM switch later on.
On the other hand, your KVM Switch also has to be present to keep track of all the modes and
parameters requested by the OS running on each connected PC.
If your computers are with serial mouse connections and AT style keyboard connections,
you should use the AT-to-PS/2 adapters specified in appendix C, Cable Diagrams. Note that even if
you have an existing 6-pin mini-DIN to 9-pin serial adapter that came with your serial mouse, it
might not work with your KVM Switch, since it might have a different wiring configuration.
The cable distance from your keyboard, video and mouse to your PC should be within 25
feet (or 7.6 m) as to ensure signal quality and proper transm ission. If you want to extend the
distance over, use of a Cat5 Extender is recommended.
Now the KVM Switch is ready to operate as soon as you turn on any of the attached
computer.

Chapter 2 Installation
2.4. Connect Your PCs and Peripherals to
Multiple Daisy-chained KVM Switches
If you use only a single KVM Switch and hence have no need for cascaded applica tion of
multiple KVM Switch units, just skip this section.
To add port capacity, multiple TK-802R/TK-1602R KVM Switches can be cascaded
in a daisy-chain configuration to maximize the number of connected computers up
to a total of 256 computers (with 16 units of TK-1602R KVM Switches). This
cascaded application is obviously advantageous when groups of computers are
dispersed and with some considerable distance from each other. Each cascaded
KVM can be away from the next KVM Switch up to 30 meters (dependent on your
cable type), thus expanding the applicable distance of only one single KVM switch
yet with the convenience of centralized control by one master KVM unit. Control
commands can then be extended to groups of computers on the master KVM
Switch on remote end through this daisy-chain connection.
The KVM Switch units that are to be daisy-chained do not have to be of the same port
capacity. In fact, you can daisy-chain different units with different port capacity as to scale the
total port capacity more flexibly.

Chapter 2 Installation
Before connecting any PC or peripherals to your KVM Switch, make sure that the power
adapter is disconnected from your KVM Switch and all PC or peripherals to be attached to the KVM
Switch should be turned off, too. If your PCs are not turned off while connecting to the KVM Switch,
the shared keyboard and mouse won’t be recognized correctly.
Your multiple daisy-chained KVM Switches have to be set up and running before you can
connect any PC or peripheral to any KVM Switch.
Daisy-chain Multiple KVM Switches
Step 1. Make sure your KVM Switch, your PCs and peripherals are all in powered-
off state. If not, turn the power off for the KVM switch, PCs and peripherals.
Step 2. Connect the shared keyboard, PS/2 mouse and monitor to the console
connectors on the rear of the master (first) KVM Switch.
Step 3. Connect the power adapter cord to power on the master KVM Switch.
Step 4. Use a daisy-chain cable to connect the daisy-chain port (labeled daisy-
chain in) of the master switch to the console port of the second switch. Then
connect the power chord to power on the second KVM switch.
Step 5. If there is yet another third KVM Switch to be daisy-chained, just repeat
step 4 to connect the daisy-chain port of the second switch to the console
port of the third KVM switch. Likewise, follow the same connection principle if
there is still more KVM Switch(es) to join in the daisy-chain.
Step 6. After you have set up and powered up the daisy-chain connection of
multiple KVM switches, you have to perform a first-time initialization for all
the switches either by (1) pressing and holding down Button 1 on the master
switch for at least 2 seconds, or (2) using the hotkey sequence: ScrollLock +
ScrollLock + End for daisy-chain initialization.
DO NOT PRESS Button 1 on any slave switch since this will initialize only the switches
“downstream” from the slave switch on which you perform a reset .
You can daisy-chain a total of up to 16 units of KVM Switches, and command up to 256
computers (the number will vary depending on the switch combination).
Connect your computers to multiple daisy-chained KVM Switches
Now your multiple daisy-chained KVM Switches should all be powered on and properly
initialized ….
Step 7. Connect each computer system (still in powered-off state) in turn either with
the individual keyboard cable, mouse cable and video cable, or the 3-in-1
keyboard/video/mouse combination cable for your convenience. Then power
on each computer.
The KVM Switch has to be turned on and properly connected to your PC prior to your
booting up any PC. Please follow the correct boot-up sequence. The reason is that: while your PC is
booting up, it has to communicate with your keyboard and mouse and consequently gets response
from them. If your KVM Switch has not been running and connected to your PC, your PC might
have difficulty recognizing your keyboard and mouse, even if you turn on the KVM switch later on.
On the other hand, your KVM Switch also has to be present to keep track of all the modes and
parameters requested by the OS running on each connected PC.

Page 16
Chapter 2 Installation
Now the KVM Switches are ready to operate as soon as you turn on any of the
connected computer.
2.5. Initialize your KVM Switch
2.5.1. Reset without disconnecting or powering down your
computers
The KVM Switch can be reset without disconnecting or powering down your
computers either by (1) pressing down Button 1 on the front panel for 2
seconds, or by (2) the hotkey sequence ScrLk + ScrLk + End. Note that each
keystroke should be followed by its next keystroke within a delay of no more than 2
seconds.
Note that, after you have set up a daisy-chain of cascaded KVM Switches, and you want to
initialize this daisy-chain of multiple cascaded KVM Switches for the first time, you should perform
the reset on the first (master) switch (that is, the first bank) to initialize. Also remember to turn on
all the other switches on the daisy-chain. The reason is that the first (master) switch will send
message to the slave units. If the slave units are not there to receive/respond to this reset message,
system errors will occur. However, if you want a reset later during your operation, it is allowable
to be performed on switches other than the master one.
If a reset is successfully performed, you should see the switch bank number which is default
to 1) being displayed on the 7-segement LED displays. If you are using multiple KVM switches in a
cascaded application, you should have different switch bank number being displayed on each bank.

Chapter 3 Operation
3. OPERATION
This chapter provides general guidelines for the KVM Switch operations. Before you
begin operation of the KVM switch, it is strongly recommended that you read this
chapter in advance.
3.1. Control Interfaces
There are three ways to operate your TK-802R/TK-1602R KVM Switch: Frontpanel buttons, keyboard hotkeys and OSD Menu options. The operation details
of these three control methods are detailed as follows:
3.1.1. Front-panel Buttons
The front panel push buttons are used to directly select the active channel that can
be controlled by the shared keyboard, mouse and monitor. Pressing the key during
normal operation will cause the corresponding channel to be selected.
The first button (from left) could also serve as a reset/initialization button when you
press and hold it down for over 2 seconds.
The last button, when pressed and held down for over 2 seconds, could also
activate the autoscan function.
For reset, you could also use the hotkey sequence: ScrLk + ScrLk + End. Only that the scrolllock key should be pressed twice within 2 seconds.
3.1.2. Keyboard Hotkeys
Some network professionals prefer hotkey controls as the most convenient and
quickest way to operate the KVM switch. Most of the hotkey control commands are
preceded by two consecutive Scroll Lock keystrokes (done within 2 seconds), and
then followed by specific command key or key sequence:
Hotkey control command = ScrLk + ScrLk + Command key (sequence)
In most cases, it will take at least three keystrokes to complete a command. In
certain case, it will need 5 strokes (such as in selecting specific bank and port
number for active channel) to complete one.

Chapter 3 Operation
All the available hotkey commands are summarized in the following table for your
convenience.
For hotkey command, you should use the number keys on the upper row of the keyboard
instead of the number pad, which is invalid for hotkey commands.

OSD (On Screen Display) is a menu that is superimposed on your screen. On the
OSD Menu, you will have a listing of the available banks and channels for selection
and the currently online status of each channel. You can use it to control the KVM
switch with more convenient and intuitive menu-driven operation. The OSD menu
also allows you to rename your computer (up to 9 characters), and to find the
specific computer by its name. It also allows you to password-protect your KVM
switch system.

solar symbol, , indicates that it is currently connected to the KVM Switch and thus
feeding power through its PS/2 interface to the KVM Switch. Others that are not
seen with a little solar symbol after them are currently not connected.
The computer name that is inversely illuminated by a magenta background color
indicates that it is currently active, and you can perform operation on it by your
keyboard and mouse.
The OSD options that are followed by a rightward arrow, , indicate that you can
expect at least another level of submenu beneath the first level.
3.1.4. OSD Navigation

3.2. Operate the Switch
The following will describe each command operation of the KVM Switch and
available ways to execute the commands, either by a front-panel button, a keyboard
hotkey sequence or an OSD Menu option.
<Select PC>
Front-Panel Button
Press the corresponding button on the specific switch, to which the channel you
want to select is connected.
Hotkey
Select PC =
For example, when with multiple daisy-chained KVM Switches configuration, if
you want to select bank 3 port 7, you should press the following keystrokes:
Select PC =
However, when using single KVM Switch configuration, if you want to select port 7,
you should first press its default bank number 01 and then the port number 07:
Select PC =
Since the single KVM Switch bank number is default to 01 (i.e. itself a master KVM Switch on
its own), therefore you should always specified its bank number by “01”.

APPENDIX C TROUBLESHOOTING
Keyboard and Mouse problems
Problem: Keyboard/mouse won’t move the cursor on the screen, or mouse
movement becomes erratic or flips around.
Solution:
Check the following points to troubleshoot your keyboard/mouse problem:
(1) Connect your keyboard and mouse to the KVM Switch only when the PCs are in
powered-off state. Otherwise, you have to reboot your PCs.
(2) Verify that your keyboard/mouse and the computer are all properly connected to
the KVM Switch. If not, connect them properly and reboot the computer again.
(3) Make sure you have installed the proper mouse/keyboard driver on the
computers for the type of your mouse/keyboard. If not, install the driver and then
reboot your computer.
(4) After you have checked that all the above requirements for a proper
keyboard/mouse connection are met, then reset your KVM Switch again by
pressing the hotkey sequence: ScrLk + ScrLk + End (or push the last port button
for over 2 seconds). Then reboot the computer and check if the keyboard/mouse
activities could be recognized by your connected computer.
(5) If the above procedures still fail to troubleshoot, try to plug off and then plug on
the Keyboard/Mouse cable to the console port of your KVM switch, and try to
reboot your computer again.
(6) Also refrain from plugging the keyboard/mouse cable while the PC is still running.
Once it comes unplugged, even if you plug back the connection again in short
time, you might have to reboot your PC to resume the normal keyboard/mouse
connectivity.
(7) Also check the specifications of your KVM Switch to see whether it requires
special KVM cables for connection with computers. If so, use the cable that is
required by your KVM Switch.
If you have checked all the above and still your mouse/keyboard does not work,
please contact your local technical support.
According to feedbacks from customers and also our own service experience, most mouse
failures are caused by inadvertently switching to other PC port while a specific PC port still
undergoing the booting process. The cause of the mouse failure over that specific PC port lies in that
port switching to other PC port, while a PC port has not completed its booting process, sometimes
will cause the mouse emulation for the latter to be interrupted and hence fails. Therefore, try to avoid
switching port while a specific PC port has not completed its booting (specifically mouse emulation
during booting process). Wait until it has completed booting to the OS environment, and then
perform the port switching to other PC ports.

Appendix C Troubleshooting
Video Display Problems
Problem: The screen won’t show properly on my monitor or flat panel display.
Solution:
Check the following points to troubleshoot your screen display problem:
(1) Verify that your video cables have connected properly between KVM Switch and
the PC and also between the KVM Switch and the monitor.
(2) Check that the video setting of the computer does not exceed the highest
resolution support of the KVM Switch. If you choose a resolution that is beyond
the video support of the KVM, the screen on your local console might show up
as blank or striped screen due to out-of-range or out-of-sync. If that is the case,
modify both the screen resolution and frequency as within the support range of
your KVM Switch.
Problem: My screen shows excessive ghosting, speckles or stripes.
Solution:
Check the following points to troubleshoot your screen display problem:
(1) Ghosting and/or stripes on screen is probably due to excessive electromagnetic
interferences from external environments that come to compromise video signal
integrity. Check the entire path of your video cable layout and see whether
there is any undue presence of a strong electromagnetic source such as large
motor, power cable or other significant electromagnetic source. If there’s any,
remove it or try to route your video cables so as to avoid or minimize its
interference.
(2) Some older monitor might show inferior display screen when using a screen
mode that is beyond its normal support range. If that is the problem, try to use
another screen mode that is “friendlier” to your monitor
