Introduction

Advantages and Features

K5EXT300 is a new KVM extender technology that utilizes CAT5 media technology to extend your console

up to 300m/1000ft away. It allows you to locate your server physically far back from the user due to security

or spatial concerns. It is especially useful for setting up a highly flexible computer/user topology over a long

distance, either over an exhibition room, work floor, security room, locked server room, or other mission-

critical scenarios. This advanced KVM extender not only extends your keyboard, monitor and mouse, but

also serial port, audio speakers and microphone on a single CAT 5 UTP cable, with satisfying video quality

and audio output.

K5EXT300 comprises two disparate units - K5LC and K5CMLC. K5LC is the local console unit, i.e., the

receiver on one end of the UTP cable. K5CMLC is the computer module with local console, i.e. the

transmitter on the other end of the UTP cable. However, K5CMLC also provides a local console, so that

users can also access the computer at the local end, in addition to the remote end on K5LC.

The firmware can be upgraded whenever is needed to enhance compatibility or functionality. For the flash

upgrade procedure, please refer to the Flash Upgrade Operation Guide provided with the new version of

firmware upgrade file.

Installing the Extender

Before you install the two pieces of K5EXT300, you should have these items on the

checklist ready:

1. The computer for extension should be one with either PS/2 or USB interfaces.

2. You should check the display mode of the computer to be within 1600 x 1200 pixel dimension. And

refresh rate to be one that is more commonly used such as 60Hz, etc.

3. Since the CAT5 KVM extender supports only standard 5-key mouse and keyboard, any more advanced

mouse/keyboard function will not be supported by CAT5 extension.

4. Use good quality UTP cable (max. 300m/1000ft). Note that good quality cable will give better video

outcome with longer distance span.

5. Any cabling distance longer than 300m/1000ft will experience more signal degradation with longer span.

However, good quality cable can reach out farer away.

6. The choice of path of the CAT5 UTP cable should not only take into account the shortest possible path,

but also one that is relatively farer away from any significant electromagnetic interference source.

7. Prepare one or two sets of keyboard, mouse, monitor, mic and speakers - one set for console 1 and the

other set for console 2.

8. There should be power outlets near where you locate the extenders.

Plan the layout path and deploy the UTP cable for extension

Step 1. Plan the path through which the UTP cable will be deployed across the distance between the K5LC

and K5CMLC. You should choose the layout path not only base on shortest possible length

consideration, but also on least electromagnetic interference.

Step 2. Lay out the UTP cable according to your planned path.

Configure the K5CMLC (Local)

Step 3. Connect one end of the UTP cable to the CAT5 Extension port of the K5CMLC. (Connector n)

Step 4. Connect the power adapter to the K5CMLC to power it up before connecting any computer or cables

to it. (connector a)

Step 5. Connect the K5CMLC to the computer, using the Slim 3-in-1 PS/2 KVM cable (connector c) and/or

the USB cable (connector f). (Note that if you need to connect with the USB interface, you should

connect the USB cable to the computer since the Slim 3-in-1 PS/2 KVM cable supports only the

PS/2 interface.)

Step 6. Set up Console 1: Connect a set of keyboard, mouse, monitor as well as a set of speakers and

microphone to the K5CMLC Console ports (connectors g, h, I, I, k, l, m).

Step 7. Power on the computer, and check the keyboard, mouse, video and audio output and mic input on

Local Console 1 to see if it works fine. If should work fine before you proceed to next steps.

Configure the K5LC (Console2)

Step 8. Connect the other end of the UTP cable to the CAT5 Extension port of the K5LC (connector 11).

Step 9. Connect the power adapter to the K5LC (connector 1) to power it up before connecting any devices

to it.

Step 10. Set up Console 2: Connect a set of keyboard, mouse, monitor (connector 4, 5, 6, 7, 8) as well as a

set of speakers and microphone (connector 9, 10) to the K5LC Console ports. If serial extension is

used, you may also connect a serial device to the serial port (connector 3).

Step 11. Check the keyboard, mouse, video, audio output and mic input on the Local Console 2 to see if it

works fine. At this time, the video might be blurred since it is not yet adjusted and optimized.

Step 12. Adjust the video parameters to optimize the display output (Refer to OSD Menu/Video page for

details).

Using the OSD Menu

The CAT5 KVM Extender provides intuitive OSD Menus facilitate control and setup operations. Users can

set up the video, audio, serial extensions as well as password protection, auto logout, etc.

To open the OSD Menu, hit the following keyboard hotkeys:

Hotkey sequence = [ScrLk]*+ [ScrLk] * + Space

* User-configurable from among SCROLL LOCK, CAPS, ESC, F12 or NUM LOCK

Changing the Hotkeys

The hotkey is default to ScrLk + ScrLk. To change the hotkeys go to the OSD System page and select any

one of the five alternatives - SCROLL LOCK, CAPS, ESC, F12 or NUM LOCK.

Each keystroke within a hotkey sequence should be pressed within 2 seconds. Otherwise, the hotkey

sequence will not be validated.

Navigating into the OSD Menu

Esc: Exit,

ÅÆLeft/Right cursor: change value in the menu option

ÇÈUp/Down Cursor: Select the option item.

F1: go to Main Menu

F9: Logout the OSD Menu (However, if the password protection is not enabled, the Logout feature

will not be available

TAB: Go to the next setting page.

These keys are listed explicitly on every OSD setting page for your ready reference.

OSD Menu/Main page

This is the Main Menu of the OSD Menu Control and it is also the first page you will see when you hit the

keyboard hotkeys - Scrlk + Scrlk + Space - to open the OSD Menu. From the Main Menu, you can go to

the Video Page, Status Page, Serial page and System page. Highlight the page name and hit <Enter>.

KEXT300 User Manual Rev 1.3

OSD Menu/Video Page

The Video page allows you to adjust the video parameters such as brightness, sharpness, Red Delay and

Green Delay. The ranges of adjustment of these parameters are

Brightness: 0 ~ 64

Sharpness: 0 ~ 64

Red Delay/Blue: -31 ~ +31

Green Delay/Blue: -31 ~ +31

In order to achieve optimized video output on the remote console (K5LC), you must adjust these four

parameters. For details, please refer to next section, Optimize the Video Display on the Remote Console.

OSD Menu/Audio Page

The Audio page allows you to toggle the audio ON/OFF, and to adjust the volume of the sound output on the

K5LC unit.

Audio: toggle On/Off the sound output on the remote console.

Volume: adjust sound volume output on the remote console

To achieve an optimized audio output on the remote console, you might need to adhere to the following

guideline:

1. Adjust the computer volume the highest level that does not saturate K5CMLC input

To do that, play some good music on the computer and hear it from K5LC. Starting from zero, increase

the computer volume. As soon as saturation appears (this distortion phenomenon is very easy to notice),

diminish slightly the computer level. This will give the audio signal the best amplitude for digitalization.

If the volume output is too small, adjusting the volume on K5LC will not help to give good sound

amplitude.

2. Adjust the sound volume output on K5LC at you convenience

Use the slide bar on the OSD menu (Audio page/ Volume) or hot keys: Scrlk + Scrlk + ↑and Scrlk +

Scrlk + ↓

OSD Menu/Status Page

The Status page displays the firmware versioning information of the K5LC and the K5CMLC. The

versioning number is actually a date code, which has the form of DDMMYY.

OSD Menu/Serial Page

The Serial page allows you to set up the serial connection extension. It must correspond to the computer

settings. You must configure the baud rate, the number of data bits, the parity type, the stop bit width and the

flow control method.

The ranges of adjustment of these parameters are

Baud Rate: 300, 1200, 2400, 4800, 9600, 19200

Data bits: 5, 6, 7, 8

Parity: None, Odd, Even

Stop bits: 1, 2

Flow Control: None, Hardware, Xon/Xoff
