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.

Thus the red indicator shows forth the current connected state of the specific port.

The green LED indicator indicates the currently active channel.

When the switch is in a “locked mode” (also known as “password protected mode”), the green

LED of the active channel will be flashing to indicate this locked state. Also all front-panel button operations will be disabled while in locked state.

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 keyboard, video and mouse, but also save you finally it saves you precious productivity boost.

time money

by eliminating the needs for multiple sets of

space

from desktop, factory floor or office, and

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

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.

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 keyboard. 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 are 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 transmission. 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.

Page 13



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 application 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.

Figure 2-2 Daisy-chaining multiple KVM switches in a cascaded application

Page 14



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 poweredoff 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 15



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.

Page 16



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: Front- panel 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)

Within 2 seconds

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.

Page 17

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.

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 =

Scr

Lk

Scr

Lk

(a) (b) (y) (z) bank port number

(01 ~ 16) number

(01 ~ 16)

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 =

Scr

Lk

Scr

Lk

0 bank number

(03)

3 0 port number

(07)

7

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 =

Scr

Lk

Scr

Lk

0 1 0 7 bank number

(01) port number

(07)

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”.

The Password Configuration (PWD CONFIG) function is default to “No password protection”.

On the other hand, if the password protection is enabled, it means every time when the

KVM Switch is reset, it will prompt the next user for password input. This feature will ensure further security over local console to ward off the possibility of any band-intention or accidental tempering of your server management by other unauthorized persons. If you have a great concern over local console security, you should have the password protection

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.

Page 31

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
