DUCTION

INTRODUCTION

The SL-KX-300 CAT5 KVM Extender can extend your keyboard,
monitor and mouse up to 300mtr away from your computer on a
single CAT 5 or CAT 6 UTP cable.

The CAT5 KVM Extender comprises two distinct units - the
Receiver (RX) Unit and the Transmitter (TX) Unit. The Transmitter
includes local console ports and allows a user to access the
computer at the local end, while also extending its keyboard, mouse
and video up to 300mtr to the Receiver unit at the remote end.

The Receiver Unit has a built-in 2 port KVM switch, and therefore
can also be connected to another computer at the receiver end and
perform switching between the remote computer (connected to the
TX) and the local computer (connected to the RX).

Applications include remote access of computers or servers for
security reasons, factory floors or warehouses not environmentally
suited to a computer or point of sale applications where space for a
computer is limited. It allows the user to manage and control the
computer at both locations together with the capability of switching
between the original computer and a second computer on the
Receiver end.

INSTALLATION

Before you install the two pieces of the CAT5 KVM Extender, 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. Prepare 1 or 2 sets of keyboard, mouse, monitor - 1 set for
console 1 (on the TX unit) and the other set for console 2 (on
the RX unit ).

3. If using a monitor on both sides, the two monitors used (one
on the TX side and the other on the RX side) for display
should be of the same native resolution to ensure maximum
compatibility.

4. You should use standard keyboard and mice, since the
CAT5 KVM extender supports only standard 5 button mice
and keyboard. Any more advanced mouse/keyboard function
may or may not be supported by this CAT5 KVM extender.

5. Use good quality CATx UTP cable (max. 300mtr). Note that
good quality cable will give better video outcome over a
longer distance.

6. Any cabling distance longer than 300mtr will experience
more signal degradation. However, good quality cable can
reach even beyond the maximum 300mtr with satisfactory
results.

7. The choice of path of the CATx UTP cable should not only
take into account the shortest possible path, but also one
that is relatively far away from any significant
electromagnetic interference source.

Plan the layout path and deploy the UTP cable for extension
Step 1. Plan the path through which the CATx UTP cable will be

deployed across the distance between the Transmitter
and the Receiver. You should choose the layout path not
only based on the shortest possible length consideration,
but also on the least electromagnetic interference.

Step 2. Lay out the UTP cable according to your planned path.
Configure the Transmitter Console
Step 3. Connect one end of the CATx UTP cable to the CAT5

Extension port of the Transmitter. (connector i)

Step 4. Connect the power adapter to the Transmitter to power it

up before connecting any computer or cables to it.
(connector h)

Step5. Connect the computer to the Transmitter using the

included 3-in-1 KVM cable (connector j)

Step 6. Connect a USB keyboard, USB mouse & VGA monitor to

the Console ports (connectors c, d, and l).

Step 7. Power on the computer, and check the keyboard, mouse

& video are working before you proceed to the next steps.

Configure the Receiver Console
Step 8. Connect the other end of the CATx UTP cable to the

CAT5 Extension port of the Receiver (connector 9).

Step 9. Connect the power adapter to the Receiver to power it

up before connecting any devices to it. (connector 8)

Step 10. Set up Console 2: Connect a USB keyboard, USB

mouse & VGA monitor to the Receiver’s Console ports
(connectors 3, 4 and 12).

Step 11. Check the keyboard, mouse & video on Console 2 are

working.

Step 12. Adjust the video parameters to optimize the display

output (Refer to OSD Menu/Video section for details).

Step 13. You can connect a second computer to the Receiver if

needed: Connect the computer to the computer port
using the included 3-in-1 KVM cable (connector 10)

Transmitter console only)
While you are at the Transmitter Console, you can turn Remote

Console On/Off or make it View Only by the following:
Hotkey sequence = [SCROLL] + [SCROLL] + M + (y)

(y) = 1, 2, 3

(y) = 1, Full access (keyboard, mouse and video)
(y) = 2, Access Denied (no keyboard or mouse and blank screen)
(y) = 3, View only (only video, no keyboard or mouse control)

When the remote console is turned OFF, the video screen will
become blank and the keyboard and mouse will be disabled.

When the remote console is in View Only Mode, the user can only
see the screen while access to keyboard and mouse control are not
available.

Optimize the Video Display on the Remote Console

To achieve an optimized display output on the remote console (i.e.
the Receiver) you will need to adjust the various video parameters
such as Brightness and Sharpness in an optimized combination
that gives you the best video display.

Please follow the procedure below to achieve an optimized display
output on your remote console screen (on RX unit):

Step 1. Choose a video display content that you think will be
suitable to serve as a reference for the visual adjustment. You can
choose a document that integrates texts and graphics so that you
can use it as a reference to achieve an optimized video display for
either textual or graphical content on the Receiver video output.
One alternative can be the visual testing program provided by the
display card vendor.

Step 2. Adjust the Brightness and Sharpness - First, invoke the
OSD menu by hitting the hotkey, SCROLL + SCROLL + Space,
then go to the Video Setting submenu.

Next, adjust your video display for an optimized output. The
Brightness adjustment can help you to tune the picture luminance
as a whole to lighter or darker output that best suits your visual

perception. The Sharpness is the edge contrast that you will
perceive.

Adjust the Brightness: The brighter the picture, the more
luminance will be added to the picture as a whole.

Adjust the Sharpness: To add more sharpness to the
picture is to help you distinguish more detail out of the edges
of a line or shape.

When you have adjusted the Brightness and Sharpness to achieve
your desired level, you can then move on to adjusting the Red
Delay and Green Delay to achieve your optimized video output.

Step 3. Adjust the Red Delay and Green Delay: the Red, Green
and Blue are the primary colors that constitute our color perception
scheme on the monitor.

The CAT5 extender uses different wires in the UTP cable to carry
the signals of different primary colors. The different wires in the
twisted-paired cable are all slightly different overall lengths and the
longer the CATx cable, the greater the difference in length between
wires.

This difference in length causes the red, green and blue colours to
become out of sync. You will need to adjust the delay time for
certain colour signals on certain wires to make the three colour
signals arrive into the display in good sync.

The CAT5 KVM Extender requires you to manually adjust only the
Red delay and the Green delay - the Blue delay is automatically
tuned and optimized by the machine according to the other
concurrent video parameters.

The values of the Red delay and the Green delay will be limited
within a preset difference range. This means, whenever you try to
adjust either the value of the Red delay or the Green delay to be
outside of the allowable preset difference range as compared to the
value of the other colour delay, the other colour delay will be
automatically adjusted to be within the difference range to prevent
the video from being perceptibly disoriented.

With the Blue delay automatically tuned in relation to the other
colours and the Red and Green delays limited within a comfortable
difference range, the SL-KX-300 CAT5 KVM extender facilitates an
easier and more intuitive way for video optimization.

No Video Troubleshooting
Q. When I connect a monitor to the CAT5 KVM extender, it

does not display any video.

A. If you encounter no video or other display problems with a
specific monitor, you should try to copy the EDID information from
the smaller monitor among the local monitor and the remote
monitor to see if this can eliminate the display problem.
