Introduction
Features
This product has a number of unique features that allow transparent remote operation of your
PC.
•Access your CPU up to 300 Meters away. You need only a single CAT 5 twisted pair cable per
each VGA channel. Please use installation cables (with solid wires) - patch cables (with
stranded wires) are not useful for bridging distances.
•Keyboard adjustable Video Equalisation - Compensates for loss of image quality due to cable
length
•Fully buffered signals to ensure consistent remote operation of you PC
•PS/2 keyboard and PS/2 mouse emulation allowing you to ‘Plug & Play’ - Intelligent keyboard
and mouse emulation ensures the PC boots and operates correctly under all possible
circumstances as well as allowing ‘Plug & Play’ initialisation of the remote keyboard and
mouse.
Operation
The SDBX-Cat5-KVM-Extender is simple to operate and works with all operating systems - no
software is required. Just connect the units up as described and you’re ready to work. Complete
keyboard and PS/2 mouse emulation allows you to ‘Plug & Play’. Your PC will boot even if the
remote end of the link is not powered or the keyboard and / or mouse are disconnected.

Cat5 interconnect cable
The Local and Remote Units are interconnected by industry
standard structured cabling (Category 5, Cat5e, Cat6, Cat7
UTP/STP, 4-pair) terminated with RJ45 connectors. This
cable is not supplied with the Extenders.
The cable used should be solid trunk cable.Stranded
patch cable will result in poor quality video.Note: That
failure to wire the twisted pairs correctly will impair the
video quality dramatically and / or prevent correct
operation.
The Mini Extender is designed for use up to a maximum
cable length of 300 Meters. At this length the video quality
should still be acceptable even at a screen resolution of
1280x1024 (75Hz).
Although a single continuous length of interconnect cable is
preferable, operation is possible through multiple patch
panels. However, the more patch panels the cable is routed
through, the greater the chance of video signal degradation.
Using other types of structured cabling
Although specified for Category 5 cabling, the Mini Extender
system has been tested on CAT 3 cable and on pairs within
a 25-pair UTP trunk cable.
SDBX/S1, SDBX/SA1, SDBX/D1 and SDBX/DA1 use single CATx cable, which carries all video
and data signals
SDBX/S2, SDBX/SA2, SDBX/S4 and SDBX/SA4 use one single Cat5 cable per VGA port. The
CATx cable connected to ‘Interconnect 1’ carries Video Channel 1 & all data signals. This is the
primary interconnect. Secondary CATx cables (Interconnects2-4)carry Video Channels2-4.
In order to send Keyboard, Mouse, Audio and Serial signals to the PC the primary interconnect
must be connected.
The primary interconnect does not have to be connected in order to use the keyboard
attached to the Remote Unit for set-up. However, if the primary interconnect is
disconnected the keyboard cannot be used for configuration for 15 seconds after
disconnection (to maintain data integrity).
LED Indicators
There are two status LED(s) on each RJ45 connector:
Green Led: OFF Remote Unit is not powered
ON Remote Unit is powered & no video found
FLASH Remote Unit is powered, Video sync found
Yellow Led: OFF No data transfer with Local Unit
FLASH Data transfer with Local Unit
ON Remote Unit in Command Mode
The Yellow LED is only active on the Primary Interconnect (Channel 1)

Getting started
The SDBX CAT5 Extender consists of a Local and a Remote Unit interconnected by a single or
up to four structured cables. The CATx cable connected to ‘Interconnect 1’ carries Video Channel
1 & all data signals. This is the primary interconnect. Secondary CATx cables (Interconnects 2 -
4) carry Video Channels2-4.TheLocal Unit is connected to the PC’s keyboard, VGA and PS/2
mouse ports. The keyboard, monitor and mouse are connected directly to the Remote Unit, which
is powered by a power supply whilst the Local Unit is powered by the PC.
Connecting Up
•Switch off your PC and power up the Remote Unit by connecting the mains adapter and
switching it on. Only use the mains adapter supplied.
•Connect all remaining cables as shown in Figure 2.
•Power on your PC and check that the keyboard operates correctly. Boot an operating system
(such as Windows) or application you intend to use. Check that the mouse functions (if
required).
•Check that the link integrity LED on the local unit flashes on and off.
We recommend that the complete system is tested in one room before permanent
installation. If a long interconnect cable is not available, use a patch lead to test basic unit
operation with your PC.
All configuration and video tuning is carried out using the keyboard connected to the Remote
Unit. A hot-key sequence is used to enter command mode where settings may be adjusted and
certain modes of operation configured.
Commands - Overview
If there is not mentioned something else, the §- key and the ¨- key refer to those keys, which
are located at the left side of the keyboard. Keys on the right side of the keyboard will regularily
NOT cause to execute the respective command! Keys, oted together with a ‘+’ sign, must be
pressed simultaneously or sequentially, by holding each key pressed, until all keys of this
sequence are pressed.

In Command Mode the keyboard LED(s) will flash (as described below) to indicate which video
channel is currently selected. In Command Mode the front panel yellow LED will be continuously
lit. Command Mode will automatically time out after 30 sec of inactivity and all settings will be
saved to EEPROM.
nExit Command Mode & Save °
Exit Command Mode and save all settings to EEPROM.
nExit Command Mode Without Save §°
Exit Command Mode without saving changes to EEPROM.
nSelect Individual Video Channel For Adjustment 1or 2or 3or 4
Apply subsequent video adjustments to the selected channel. On Command Mode entry the
default video channel is 1 You may only select video channels that are available on the Remote
Unit model being used. The keyboard LED(s) will regularly blink a number of times to indicate
which video channel is currently selected.
nSelect ALL Video Channels 0
Use Channel 0 to apply subsequent video adjustments to ALL video channels simultaneously.
Useful for setting up multi-head systems, where the cable lengths are almost identical. Only
applicable on dual/quad video models. The keyboard LED(s) will flash slowly to indicate that
Channel 0 (ALL video channels) is selected.

Adjust Low-Frequency for the selected video channel(s). Use to remove ‘video smearing’ prior to
setting HF EQ. Adjust until black smears to the right of large objects such as window title bars
just disappear. Too much compensation will cause white streaks to appear.
nIncrease HF Equalization (Coarse) H+£
Increase HF Equalization (Fine) H+¤
Decrease HF Equalization (Fine) H+¥
Decrease HF Equalization (Coarse) H+¢
Adjust High-Frequency for the selected video channel(s). Use to sharpen image after setting LF
EQ. Adjust until a white edge to the right of small characters just starts to appear. After adjusting
HF you may need to finely adjust LF EQ again.
nNext Assisted EQ Setting (+25m) §+³
Previous Assisted EQ Setting (-25m) §+´
Assisted EQ steps through a table of preset LF & HF EQ values for different cable lengths (in
25m increments calibrated from 0 to 375m). Use Assisted EQ to save time by quickly setting the
approximate EQ for the currently selected video channel(s). Fine adjustments may then be made.
nReset EQ & Delay Values §+²
Set all video EQ (HF & LF) and delay values to zero for the currently selected video channel(s).
Reset all video channels by selecting Channel 0 prior to issuing this command.
nReset EQ Values §+¶
Set all video EQ (HF & LF) values to zero for the currently selected video channel(s). Current
delay values are not affected. Reset all video channels by selecting Channel 0 prior to issuing
this command.

Compensate for Cat5e & Cat6 skew on any colour for the currently selected video channel(s).
Cat5e and Cat6 cables have a different skew on the different pairs of wires. Because of this, the
wires do not all have the same length, there are delays on the synchronous data stream on
different pairs. This causes, that i.e. the green component of a pixel is faster than the red or blue
component. Now all characters and graphics get a green fringe at the left side. Skew
