2. Overview

Introduction

The SD-VUE USB Mini Extender Series enables high-resolution video, USB,
stereo audio, and serial port signals to be communicated up to 50m over
Category 5, 5e, 6 or higher (CATx) cable.

A basic USB extension system comprises a Local Unit (transmitter) and a
Remote Unit (receiver). The Local Unit connects directly to the computer (or a
USB Hub) using the supplied cable(s). The user console (consisting of monitor,
keyboard, mouse and other devices) attaches to the Remote Unit. All Local
Units in the USB Mini Extender Series have video output ports, allowing a
second user console at the CPU (using further CPU/Hub ports). The Remote
and Local Units communicate video and data information along the connecting
CATx cable (see Interconnection Cable Requirements on page 12).

Within the product range, models are available with:

• Audio and serial transmission: bi-directional stereo audio (16-bit digitized)

and transparent serial COM port (to 19.2Kbps).

• Multiple video channels: single and dual heads.

information about compatibility with other products.

How to Use This Guide

This guide describes the installation and configuration of the SD-VUE USB
Mini Extender Series. Although the connection and operation of the system is
relatively straightforward, you should consider the following before getting
started:

Connection & Compatibility

Each Extender kit contains all the cables required to connect the Local Unit to
your PC or KVM switch. The remote monitor(s), USB devices and any audio
and serial equipment connects directly to the Remote Unit.

For information about connection and installation, see Installation, page 11.

Interconnection Cable

You will need CATx (any category 5, 5e, 6 or higher) cable, terminated with
RJ45 plugs, to connect the Local and Remote Units (see Interconnection
Cable Requirements, page 12).

Adjusting Video

Video signals can become distorted when transmitted over CATx cables. To get
the best from your extender system, it is essential that you:

• Set the Cable Length DIP switches on the Remote Unit correctly (see

Setting the Cable Length DIP Switches on page 13).

• Use low skew CATx cable.

Installation 11

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 USB
extender system more conveniently.

12 SD-VUE USB Mini Extender Range

Interconnection Cable Requirements

To connect the Local and Remote Units you will need CATx (any category 5,
5e, 6 or higher) cable terminated with RJ45 plugs. Please note that shielded
cable is advised to maintain regulatory EMC compliance.

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 below).

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 USB data.

• The Secondary interconnect cable connects to INTERCONNECT Port 2 on

the Local and Remote Units. This carries the additional video channel on
dual-head units and/or audio/serial data.

Technical Note: Although compatible with UTP cable, it is recommended that
shielded STP/FTP cable is used with this product, especially in electrically noisy
environments. When shielded cable is used, it is most important to ensure that
shield connectivity is maintained between the extender units.

Cable Pinning/Pairing

The following table illustrates which RJ45 connector pins the extenders use for
various signals. It also details the standard EIA-568B wiring scheme that is
recommended for most installations.

Looking into the RJ45 socket on a Remote Unit, Pin 1 is on the right and Pin 8
on the left.

Remote Unit Installation

Setting the Cable Length DIP Switches

If your application uses CATx cable less than 25m in length, you can continue
to the next section.

Mini Extender Remote Units incorporate video equalization circuitry, allowing
you to compensate for the loss in image quality that occurs when video signals
are transmitted along CATx cables. At the factory, Remote Units are configured
to optimize the video signals for Interconnect cables up to 25m in length.

If you intend to use cables of 25-50m in length:

1. Locate the DIP switches on the underside of the Remote Unit. DIP switch 1

is used for video channel 1, DIP switch 2 for video channel 2.

2. Set the DIP Switches as follows:

Interconnect Cable Length

(m)

5 – 25 OFF (default)

25 – 50 ON

DIP Switch Position

If you are carrying out a test placement prior to final installation, set the DIP
switch to the position appropriate to the test cable’s length. When your tests are
complete, set the DIP switch to the position appropriate for the CATx cable
length used in the full installation.

Technical Note: The video compensation does not adjust skew. Although skew
(color separation) can be an issue on some CATx cables, it would not normally
be observed on cables <50m. Even so, we still recommend the use of low skew
cables with USB Mini Extenders. You can test for skew by viewing the online test
card at: http://testcard.kvmextender.info

14 SD-VUE USB Mini Extender Range

Connecting the Remote Unit

To install a Remote Unit:

1. Connect your monitor, USB and other devices to the Remote Unit as shown

in Figure 2 (single and dual-head units).

If additional USB hubs are attached to the extender, the maximum
extension distance could be reduced (due to the delay imposed by each
hub). For each connected hub, you may lose up to 10m of extension
distance. Note: any USB device to which additional USB peripherals may
be attached is a USB hub (e.g. an Apple® USB keyboard).

2. 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 Appendix C: Audio/Serial Ports, page 29 for further information.

3. Connect the Primary CATx cable to the INTERCONNECT (1) socket on

the front of the Remote Unit. For dual head systems and SD-VUE/50A
(uses a second CATx cable to extend audio and serial data only), connect an
additional CATx cable to INTERCONNECT (2) (see Figure 3).

4. Connect the 5V power supply to power the unit.

Only use the power supply originally supplied with this
equipment or a manufacturer approved replacement.

5. If you are using a flat panel TFT monitor, you must adjust the clock

and/or phase, either manually or by using auto-adjust. Refer to the manual

supplied with your monitor.

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 video/USB cable, connect the Local Unit to the

CPU as shown in Figure 4.

We recommend that the Local Unit is connected directly to a CPU USB
port (Root Hub). If the Local Unit has to be connected through an external
hub, you should ensure the hub is self-powered (not bus powered), or
connect a 5V PSU (500mA) to the Local Unit.

3. If you want local access to the CPU, connect the video output(s) on the

Local Unit to suitable monitors. Connect a USB mouse and a USB
keyboard directly to other USB ports on the CPU or a connected hub.

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. For single video units, connect the CATx cable to the INTERCONNECT

socket on the front of the Local Unit. For dual-head systems, connect the
CATx cables from the Remote Unit to the corresponding
INTERCONNECT ports (1&2) on the Local Unit (see Figure 5).

7. Power up the PC.

The Local Unit normally takes power through the USB connection. In
video only applications, or when the USB interface has limited power
(from a bus-powered hub, for example), an external 5V PSU may be
required. The power LED will indicate if an external PSU is required (see
page 17).

Please contact Technical Support to obtain a suitable power supply.

4. Troubleshooting

Video

The image is not sharp, or is badly smeared.

Check that the cable length DIP switch is correct for the length of your
Interconnect cable (see page 13).

Check the Interconnect cable between the Remote and Local Units. Is it
of the recommended type (see page 11)? Is it intact along its entire
length and securely connected at both ends? Is it wired correctly?

Ensure that all video connections throughout the system are attached
securely.

Are you using an LCD panel? You must adjust its clock and/or phase
either manually or using auto-adjust.

Colors appear to be separated and there are colored borders on text and
icons.

Check the Interconnect cable between the Remote and Local Units. Is it
of the recommended type (see page 11)? Is it intact along its entire
length and securely connected at both ends? Is it wired correctly?

Are you using low skew cable? You can test for skew by viewing the
online test card at: http://testcard.kvmextender.info

I only need video extension – not USB - but I can’t get a picture.

Have you powered the Local Unit? The Local Unit gets its power from
the CPU through the USB connection and it will not operate without it.
Use an external 5V PSU as described on page 16.

The monitor sometimes goes blank for a second or two.

Check that the interconnect cable is not routed near power lines or other
sources of electrical interference. Use shielded STP/FTP cable instead
of UTP cable ensuring that the shield connection is maintained between
the extender units.

Check system grounding.
If this is a persistent problem, contact Technical Support.

Troubleshooting 19

Jitter is evident on video.

Adjust the clock and/or phase on your flat-panel. Contact Technical
Support if this fails to improve the situation.

Are you testing a system using a coiled drum of CATx cable? Try
uncoiling the cable. If this solves the video jitter, you should not have a
problem after full installation.

I can’t select the video mode I need.

For non-standard resolutions, choose the monitor manually through the
operating system, and set to ignore DDC. Contact Technical Support if
you have problems selecting your required graphics mode.

Can the extender be used with RGB video?

Yes.

USB

Why does the Extender stop working when I attach a USB hub to the Remote
Unit?

If additional USB hubs are attached to the extender, the maximum
extension distance will be reduced (due to the delay imposed by each
hub). For each connected hub, you may lose up to 10m of extension
distance. Any USB device to which additional USB peripherals may be
attached is a USB hub (e.g. an Apple® USB keyboard).

Will the USB Mini Extender work with USB 2.0?

The extender will operate perfectly through USB 2.0 Host Controllers.
However, the speed will be restricted to that of a USB 1.1 hub (12Mb/s).
Devices that are USB 2.0 compliant will operate if they are backwards
compatible with USB 1.1. If you have a device that demands the high­speed mode of USB 2.0 then it will not be compatible with the USB
Mini Extender.

Is the USB Mini Extender compatible with all USB devices?

This product range extends the distance at which USB peripherals may
be operated by making full use of the bus timeout period allowed by the
USB protocol. The extender should be compatible with the majority (but
not all) of CPU USB Host Controllers and USB peripherals on the
market.

20 SD-VUE USB Mini Extender Range

Extended USB devices are unstable and ‘drop out’.

Check that the interconnect cable is not routed near power lines or other
sources of electrical interference. Use shielded STP/FTP cable instead
of UTP cable ensuring that the shield connection is maintained between
the extender units. Check system grounding.

The extension distance is too great for your CPU/USB device
combination. Try reducing the interconnection cable length if possible.

If you are using an alternative USB cable to connect the Local Unit to
the CPU it must be less than 3m in length.

Some of my USB devices do not operate over the full range.

The maximum extension range is nominally 50m. In practice, the
maximum distance achievable may be between 40m and 60m depending
on your system and USB devices. Adding external USB hubs may
decrease the maximum extension distance by up to 10m for each hub
added. Adding bus-powered hubs in front of the Local Unit is not
recommended.

Audio

The audio is very quiet.

The audio I/O is line-level and requires amplified speakers and
connection to devices providing line-level I/O.

The audio is loud but distorted.

Check that the audio input is not greater than line level (4V peak-to­peak). The USB Mini Extender accepts line-level audio input only.

The microphone output is barely audible.

See Appendix C: Audio/Serial Ports, page 29.

No audio on SD-VUE/50A.

You need to connect the second interconnect cable which is used to
carry audio and serial data.

Troubleshooting 21

Serial

My serial device does not function.

The extender supports serial devices at data rates not exceeding 19.2K
Baud (although 38.4K operation might be possible with certain
equipment).

Check the type of flow control used by the device and CPU. The
extender supports RTS, CTS, DTR, and DSR. Some systems may
require a wiring adapter to transfer RI and DCD.

Attach the device directly to the serial port on the PC and test whether
the problem is a PC or extender problem.

Some serial devices cannot be hot-plugged. Try connecting the device to
a powered Remote Unit prior to booting the system.

22 SD-VUE USB Mini Extender Range

General Questions

The green power LED is not lit when I connect my Local Unit to my USB
hub.

Local Units normally take power from the USB connection to the
computer. Local Units may require an external 5V PSU:

- If the CPU/hub cannot provide sufficient power through the USB
connection.

- For video only applications.

Contact Technical Support for details of a suitable PSU.

Is it possible to use a cable length longer than 50m?

The maximum extension distance is nominally 50m. Some systems may
extend up to 60m and others only 40m. Once the system range limit is
reached, USB operation will cease or become erratic. For maximum
extension distance, avoid connecting additional USB hubs to the system.

Which interconnection cable is best?

The extender will operate with either shielded (STP/FTP) or unshielded
(UTP) CATx cable. However, correctly installed shielded cable is
preferred, especially in electrically noisy environments, because it
resists interference more strongly, limits ground potential differences,
and reduces emissions. To benefit from shielded cable the shield
connection must be maintained from end to end through any intervening
patch cables, panels and RJ45 connectors.

Please note that shielded cable is advised in order to maintain
regulatory EMC compliance.

Can I use CATx patch cables?

Yes, but to ensure maximum data integrity, use as few as possible. The
maximum patch cable length at each end of the link should be limited to
3m.

Can the extender system be used between buildings?

No. Ground loops could damage the extender system and attached
equipment.

Troubleshooting 23

Can multiple Local/Remote Units be used by swapping the interconnection
cable?

Local Units provide a transparent USB link, so it is possible to swap or
switch the local-remote interconnection to create a matrix-switch
system. Please call Technical Support before deploying such a system.

Can the extender be connected into our network?

Absolutely not. Regardless of the cable similarities, the data signals and
voltages used by the extender are different to those used by Ethernet and
other types of networks. Connecting the extender to a LAN hub, switch,
repeater, or other network device, or exposing it to the signal levels
present on network data lines may damage the extender and other
devices.

Appendix B: Rack Mount Options

All USB Mini Extender units can be mounted in a 19” rack in any combination
using the SDBR3 mounting kit.

SDBR3 Mounting Kit

This mounting kit allows you to mount up to three units across 1U. It contains
one rack plate and M3 countersunk mounting screws.

To mount a unit:

1. Remove the feet from the extender unit.

2. Align the holes on the base plate with the vacant screw holes on the base of

the extender unit.

3. Fasten the base of the unit to the plate of the mounting kit using the

supplied screws.

Appendix C: Audio/Serial Ports 29

Appendix C: Audio/Serial Ports

Operation & Multi-Port Configuration

This appendix describes audio & serial interface operation for SD-VUE/50A
and SD-VUE/52A.

This extender allows bi-directional stereo audio and a full-duplex serial data to
be sent across the secondary CATx interconnection cable.

Serial Interface - Set Up and Operation

No setting up or user adjustments are required.
The Remote Unit’s serial port is wired as DTE - the same as that on a PC. To

connect a serial printer or other DTE (rather than DCE device) to the Remote
Unit, you will need a Null-Modem crossover cable between the Remote Unit
and the printer. Select Xon/Xoff software flow control on the printer and PC.

A serial touch screen may be plugged directly into the Remote Unit.

Serial Interface – Handling Multiple Serial Devices

The extender’s serial interface transmits/receives six signals (3 signals in each
direction).

Normally, four of these signals are used for hardware handshaking (in addition
to TX & RX). However, because each handshaking line can support signals up
to 19,200 Baud it is possible to configure the serial interface to handle up to
three simple 2-wire (Tx/Rx only) serial links.

To do this, you will need to construct a custom breakout cable. Please contact
Technical Support for further information.

30 SD-VUE USB Mini Extender Range

Audio Interface - Set Up and Operation

The audio interface is line-level and is designed to take the output from a sound
card (or other line-level) source and be connected to a set of powered speakers
at the other end of the link.

Stereo audio may be transmitted either way across the link (simultaneously).
No setup is required unless a microphone is connected to the Remote Unit.
Connect the extender as follows:

• Take the line-level output from your sound card (green connector) and

connect to ‘Line In’ on the Local Unit.

• Connect ‘Line Out’ on the Remote Unit to a set of powered speakers.

Audio Interface – Using a Microphone

A microphone may be plugged into the ‘Line In’ connector on the Remote Unit.
There are two ways of setting up a microphone:

• The Local Unit’s ‘Line Out’ connection should normally be wired to the

microphone input (Pink) on your sound card. The sound card should then be
set up to provide additional amplification (+17dB). This is the preferred
connection method.

• Alternatively, the Remote Unit itself can provide microphone amplification.

To set this, open up the Remote Unit and locate the jumper labeled ‘MIC’
on the daughter board. Connect this jumper across the pins. The Local
Unit’s ‘Line Out’ connection should then be wired to ‘Line In’ (Blue) on
your sound card.

If your microphone is already amplified, follow the second method but DO
NOT install the amplification jumper in the Remote Unit.
