2. Overview
Introduction
The SDMX PS/2 Mini Extender Series enables two channels of high-resolution
video, PS/2 keyboard and mouse, and, optionally, stereo audio and serial port
signals to be communicated up to 50m over CATx (Category 5, 5e, 6 or higher)
UTP/STP 4-pair cable.
A basic KVM extension system comprises a Local unit (transmitter) and a
Remote unit (receiver). The Local unit connects directly to the computer (or a
KVM switch system) using the supplied cable(s). The user console (keyboard,
mouse and monitors) attaches to the Remote unit. The Remote and Local units
communicate video and data information along the connecting CATx cables
(Figure 1).
Within the product range, models are available with combinations of the
following:
•Audio transmission: bi-directional stereo audio (16-bit digitized).
•Serial transmission: transparent serial COM port (to 19.2Kbps).
•Dual access: allowing a second user console at the Local unit.

How to Use This Guide
This guide describes the installation and configuration of the SDMX PS/2 Mini
range of KVM extenders. Although the connection and operation of the system
is relatively straightforward, you should consider the following before getting
started:
Connection & Compatibility
If you have purchased an SDMX Extender kit, this will contain all the cables
required to connect the Local unit to your PC or KVM switch. The Remote
console (keyboard, monitor and mouse) and any audio and serial equipment
connect directly to the Remote unit.
If you have purchased an SDMX Remote unit, ensure that it is compatible with
your Local unit (see Compatibility, page 10).
For information about connection and installation, see Installation, page 13.
Interconnection Cable
You will need CATx (any category 5, 5e, 6 or Level 7) cable, terminated with
RJ45 plugs, to connect the Local and Remote units (see Interconnection Cable
Requirements, page 14.
Adjusting Video
Video signals become distorted when transmitted over CATx cables. To get the
best from your extender system, it is essential that you adjust the SDMX PS/2
Mini Remote unit to optimize the video image quality.
•For experienced users, there is a Quick Setup section at the start of this
guide (see page 5).
•For the full procedure, see Adjusting Video, page 23.

Installation 13
3. Installation
For first-time users we recommend that you carry out a test placement, confined
to a single room, before commencing full installation. This will allow you to
identify and solve any cabling problems, and experiment with the KVM
extender system more conveniently.
Package Contents
You should receive the following items in your extender package. If anything is
missing, please refer to Appendix F: Obtaining Technical Support, page 42.

14 SDMX PS/2 Mini Extender Range
Interconnection Cable Requirements
To connect the Local and Remote units you will need CATx (any category 5,
5e, 6 or Level 7) cable terminated with RJ45 plugs.
Interconnect cables must be solid-core type. Stranded patch cable will give poor
results over longer distances. The pairing of the cable and pinning of its
connectors should normally be in accordance with EIA-568B (see page 39).
One CATx cable is required for each video channel.
•The Primary interconnect cable connects INTERCONNECT Port 1 on the
Local and Remote units. This carries the main video channel and all data
(plus audio/serial).
•The Secondary CATx cable (connected to INTERCONNECT Port 2)
carries the second video channel.
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).
With some cables, video performance may be improved by using a cross-over patch
cable at each end or an alternative RJ45 pin-out (see Appendix D: Cable Pinning,
page 39).

Installation 15
Remote Unit Installation
To install a Remote unit:
1. Switch off all devices.
2. Connect your keyboard, monitor(s) and mouse to the Remote unit as shown
in Figure 2.
These ports may also be attached to the CPU side of a KVM switch in order
to have a Remote CPU. However, if you are attempting to use the extender
between cascaded KVM switches this may not work. Please contact Technical
Support to discuss your application.
3. If appropriate, connect audio equipment and serial devices. Connect the
audio cables as follows:
Remote Unit Audio Device
Audio Out Speakers
Audio In (MIC) Microphone
See page 41 for further information.
4. Connect the Primary CATx cable to the INTERCONNECT (1) socket on
the front of the Remote unit. If required, connect the Secondary CATx cable
to the INTERCONNECT (2) socket on the front of the Remote unit (see
Figure 3).
5. Connect the 5V power supply to power the unit.
Only use the power supply originally supplied with this
equipment or a manufacturer approved replacement.

Installation 17
Local Unit Installation
To install a Local unit:
1. It is recommended that the PC and other devices are switched off before
connection.
2. Using the supplied CPU KVM cable(s), connect the keyboard, monitor(s)
and mouse connectors on the computer (or KVM switch) to the
corresponding connectors on the Local unit as shown in Figure 4.
Ensure that you attach the keyboard and mouse connectors to the correct
ports. The keyboard connector is purple; the mouse connector is green.
If your PC does not have a PS/2 mouse port, an active serial converter will
be required - Model No: Mdapt (PS/2).
3. If you have a dual access system, connect the keyboard, mouse and monitor
for the Local console to the appropriate ports on the Local unit. The ports
may also be used to feed into a KVM switch.
4. If you have an audio and serial enabled system, connect the audio cables
between the computer and Local unit as follows:
Computer Local Unit
Audio Out (green) Audio In
Audio In/Microphone (pink/blue) Audio Out
5. If appropriate, connect the supplied serial cable between the serial port on
the computer and the Local unit.
6. Connect the CATx cables from the Remote unit to the corresponding
INTERCONNECT ports (1&2) on the Local unit.
7. Power up the PC.
The Local unit normally takes power through the PCs keyboard port. In video
only applications, this connection is not used and so an external PSU is
required. Please contact Technical Support to obtain a suitable power supply.
