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).

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>.

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 + ↓

Optimizing the Video Display on the Remote Console
To achieve an optimized display output on the remote console (i.e. the K5LC) will require you to
conscientiously adjust the various video parameters such as Brightness, Sharpness, Red Delay and Green
Delay in an optimized combination that could most satisfy your visual requirements.
Please follow the procedure below to achieve an optimized display output on your remote console screen (on
K5LC):
I. Run the Screen Test program
To facilitate the video adjustment, we provide ScreenTest.exe, a program to serve as a visual reference for
easier adjustment. ScreenTest.exe runs on Windows OS. On other OS, use a simple text page.
Find ScreenTest.exe in your Support CDROM. Either you can copy it to your desktop or you can run it
directly from the CDROM. ScreenTest.exe displays a full screen image as below:
II. Adjust Brightness and Sharpness
Open the OSD Video page. Brightness and Sharpness adjustments depend on the cable length. With cables
below 20 meters, there is almost no need for any adjustment. The longer is the cable, the more you will have
to increase Brightness to compensate for the attenuation and Sharpness to compensate for the bandwidth
decreasing.
After you have adjusted Brightness and Sharpness to achieve a passable situation, you can temporarily leave
them there and try to work on Red Delay and Green Delay so that you can see a cleaner picture for further
fine-tuning. Maybe be you will have to come back to Brightness and Sharpness after that.

III. Adjust the Red Delay and Green Delay
Red, Green and Blue are the primary colors that constitute the VGA signal. Depending on the cable quality,
these three colors may need slightly different times to travel from K5CMLC to K5LC. This phenomenon
does not appear with short cables or very good cables. K5LC allows you to adjust the R, G and B
transmission times to compensate for these transmission delay differences.
On K5LC, the Blue signal is taken for reference. The Red and Green signals can be advanced or delayed by
entering negative or positive values in the range of -31 to +31. Observe the RED-GREEN-BLUE vertical
lines and adjust Red Delay and Green Delay so that the three colors are perfectly aligned. On other OS,
observe a simple vertical black line. It must be perfectly black with no color appearing on the edges.
