Introduction
The
LKV-E235 CAT5 KVM Extender Set – 150M
extends your
keyboard, monitor and mouse from your computer up to
150M/500ft away on a single CAT5 UTP cable, with satisfying
video quality.
The
LKV-E235 CAT5 KVM Extender Set – 150M
comprises two
distinct units- The
Receiver (Rx) Unit
and the
Transmitter (Tx)
Unit
. The
Tx Unit
and the
Rx Unit
will be located each on one
end of the CAT5 UTP cable. The
Transmitter
allows user to
access the computer at the local end, while extending it across
150M/500ft to the Remote console on the Receiver, which can
therefore access and control the extended computer well as
another computer in proximity of the Receiver, due to a built-in
KVM Switching feature into the
Receiver
.
It is especially useful for setting up a highly flexible computer/user
topology over a sizable distance up to 150M/500ft away.
Applicable either over an exhibition room, work floor, security
room, locked server room, or other mission-critical scenarios, the
LKV-E235 CAT5 KVM Extender Set
allows you to locate your
server physically far back from the user due to security or spatial
concerns. And it allows the user to manage and control the
computer at both location, and with the capability of switching
between the original computer and a second computer on the
Receiver end.
This
LKV-E235 CAT5 Extender Set
also allows its user to
upgrade firmware contents 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.

Preparation before Installation
Before you install the two pieces of the CAT5 KVM Extender
Set, 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.
Prepare 1 or 2 sets of keyboard, mouse, monitor - 1 set for
console 1 and the other set for console 2.
4.
The two monitors used (one on the Tx side and the other on
the Rx side) for display should be of the same resolution, and
better of the same type or same make and model.
5.
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.
6.
Use good quality CAT5 UTP cable (max. 150M/500ft). Note
that good quality cable will give better video outcome with
longer distance span.
7.
Any cabling distance longer than 150M/500ft will experience
more signal degradation with longer span. However, good
quality cable can reach out farer away.
8.
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.
9.
There should be power outlets near where you locate the
extenders.
Out-of-the-box Installation
Take the package items out of the box and begin installation….
Plan the layout path and deploy the UTP cable for extension
Step 1.
Plan the path through which the CAT5 UTP cable will be
deployed across the distance between the
Transmitter
and the
Receiver
. 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 Transmitter Console (Console 1)
Step 3.
Connect one end of the CAT5 UTP cable to the CAT5
Extension port of the
Transmitter
. (Connector
k
)
Step 4.
Connect the power adapter to the
Transmitter
to power
it up before connecting any computer or cables to it.
(connector
j
)
Step 5.
Connect the
Transmitter
to the computer, using the Slim
3-in-1 PS/2&USB KVM cable (connector
l
). (By adding
the USB-to-PS/2 adapter that comes with your cable,
you can connect to computer using PS/2 connections.)
Step 6.
Set up Console 1: Connect a set of keyboard, mouse,
monitor as well as a set of speakers and microphone to
the
Transmitter
’s Console ports (connectors
c, d / e, f
and
n
).
Step 7.
Power on the computer, and check the keyboard, mouse,
video on Console 1 to see if it works fine. If should work
fine before you proceed to next steps.
Configure the Receiver Console (Console2)
Step 8.
Connect the other end of the CAT5 UTP cable to the
CAT5 Extension port of the
Receiver
(connector
11
).
Step 9.
Connect the power adapter to the
Receiver
(connector
10
) to power it up before connecting any devices to it.
Step10.
Set up Console 2: Connect a set of keyboard, mouse,
monitor to the
Receiver
’s Console ports (connector
3
,
4 /
5, 6
and
13
).
Step11.
Check the keyboard, mouse, video on Console 2 to see if
it works fine. At this time, the video might be blurred
since it is not yet adjusted and optimized.
Step12.
Adjust the video parameters to optimize the display
output (Refer to
OSD Menu / Video
section for details).

immediately ….
For KVM Switch Console Extension:
You can also use the
CAT5 KVM Extender to extend your KVM Switch console …. Just
connect the Transmitter unit to the console port of the KVM
Switch, and the rest of the connection is just like what has been
descried above. Thus, you can also extend the KVM switch
console up to 150M away.

On the Receiver Unit, the OSD Menu control is available to
facilitate more intuitive operations. Users can configure various
settings by the OSD Menu:
