Section 1: Introduction VN-MATRIX User Guide
What is VN-MATRIX?
VN-MATRIX is used to distribute RGB video/graphics from a source computer (or similar graphical
device) across an IP network to one or more viewing stations.
An RGB signal is captured/acquired by a VN-MATRIX unit and encoded in to a TCP or RTP data
stream for transport across a local area or wide area network. Elsewhere on the network another
VN-MATRIX unit can decode the stream back into an analog RGB or digital (DVI) signal, suitable for
display on a wide range of display devices.
In addition to an RGB signal, the VN-MATRIX can provide cross-network transport of:
Digital Audio (SPDIF), and
Serial Data (RS-232).
NOTE: Digital audio can be used to accompany a video/graphics source. VN-MATRIX cannot
transport an ‘audio only’ signal.
RS-232 serial data can be distributed between VN-MATRIX units unidirectionally as part of the source
stream, or bi-directionally independent of any source streams. A VN-MATRIX can also be configured
to accept serial remote control commands allowing simple changes to be made to system operation.
Firmware Version
This user guide is based on v3.3c firmware. You can check for newer firmware releases and user
guide updates by visiting our web site at www.electrosonic.com/support.
HINT: To check which version of firmware is currently installed, login to the web interface
(see page 41) and go to the Upgrade page (see page 82).
Extended Functionality
Support for the following extended functions has been introduced for firmware v3.0 and above:
Scaling which allows up/down scaling of sources to suit the target display. By default,
sources can only be displayed at their native resolution.
Whiteboard which allows live text and pointer interaction between users of both the local and
remote displays.
Recorder which allows recording and playback of source, whiteboard and RS-232 data
streams.
By default, these extended functions are disabled and can only be enabled by the purchase and
installation of a special license key. Please contact your Electrosonic supplier or agent for details.
These functions are not documented in this user guide.
Page 10 I458GB issue 6
VN-MATRIX User Guide Section 1: Introduction
Functional Overview
The VN-MATRIX can be configured to operate in one of two modes:
As an encoder to encode a source and stream it across a network,
As a decoder to decode a VN-MATRIX data stream from a network.
Therefore, any VN-MATRIX system will comprise at least two devices, one configured as an encoder
and the other as a decoder. However, multiple encoders and decoders can co-exist on the same
network.
On a given network any decoder has the ability to display the source provided by any encoder.
Encoder / Source Compatibility
As an encoder the VN-MATRIX is compatible with both digital (DVI) and analog (RGB) graphics
sources up to UXGA resolution (1600 x 1200 @ 60Hz, 24-bit color). See page 101 for a list of
standard supported sources.
The VN-MATRIX incorporates advanced image acquisition circuitry which can auto-detect a wide
range of source types without the need for any additional setup.
For specialist or non-standard source formats, user customizable source modes can be created using
the Web Interface. See page 66 for further details.
HINT
The VN-MATRIX provides Analog-to-Digital or Digital-to-Analog conversion via its monitor
connections. Therefore, it is possible to use a digital monitor with an analog source and vice versa.
Decoder / Display Capability
As a decoder the VN-MATRIX is compatible with both digital (DVI) and analog (RGB) graphics
sources up to UXGA resolution (1600 x 1200 @ 60Hz, 24-bit color)*. See page 102 for a list of
standard supported sources.
NOTE: By default, sources are displayed at their native resolution and format. Support for source
scaling existing within firmware v3.0 and above but must be enabled by a special license key.
I458GB issue 6 Page 11
Section 1: Introduction VN-MATRIX User Guide
Control Capability
Source Control
Loop-through connections are provided on the VN-MATRIX for the source computer keyboard and
mouse. Local keyboard and mouse control of the source computer is fully maintained while connected
to the VN-MATRIX. In addition, keyboard and mouse functions can be remotely controlled from the
viewing station.
System Setup & Configuration
Low level communications setup of the VN-MATRIX is achieved using a serial data link to the COM1
port. High level configuration is achieved via the network using the Integrated Web Management
System (see below).
Integrated Web Management System
VN-MATRIX incorporates an Integrated Web Management System (Web Interface for short). This
allows any VN-MATRIX unit on a network to be configured via a PC/laptop (on the same network),
using a standard web browser (e.g. Internet Explorer, Netscape Navigator, Opera).
One VN-MATRIX unit on the network must be designated as a ‘controller’. This unit acts as a server
for the Web Interface and also holds a database of all VN-MATRIX devices on the network.
Any VN-MATRIX unit, whether it is configured as an encoder or decoder, can be used as a controller.
The Web Interface includes a full on-line help system.
Remote Control
RS-232 serial data can be routed between selected VN-MATRIX units, for example to provide remote
control of a source.
In addition, serial commands can be input to a VN-MATRIX and routed to the controller to allow basic
control of system operation, e.g. to change source selection on displays, compression settings, or
enabling and disabling devices.
Page 12 I458GB issue 6
VN-MATRIX User Guide Section 1: Introduction
Network Requirements
VN-MATRIX uses highly efficient compression algorithms to minimize the amount of data needed to
be transported across the network.
It is, however, crucial to the effective operation of VN-MATRIX that sufficient data throughput can be
achieved, especially where multiple sources are being encoded.
The efficiency of a network will be directly affected by the speed and configuration of each element
within its infrastructure, e.g. switchers and routers. VN-MATRIX will achieve optimum transmission
results over a dedicated 1Gbps network (Gigabit Ethernet).
For more general information on networks and network performance, please refer to Appendix B on
page 128.
I458GB issue 6 Page 13
Section 1: Introduction VN-MATRIX User Guide
Example System Application
The diagram below shows an example system application utilizing eight VN-MATRIX units. Four are
configured as encoders (sources) and four as decoders (displays). Each device is connected to a
network.
Configuration of each device, including which source is displayed on which display, can be achieved
by any PC/laptop on the same network, using the VN-MATRIX Integrated Web Management System.

VN-MATRIX User Guide Section 1: Introduction
Data Transport Methods
Source data from a VN-MATRIX Encoder can be distributed to multiple displays/encoders (one-tomany) or to a single display/decoder (point-to-point).
Video data is transported from the source (encoder) to the display (decoder) using one of three
methods:
Multicast RTP
Unicast RTP
Unicast TCP
A description of each method, together with its advantages and disadvantages, can be found on the
next few pages.
I458GB issue 6 Page 15
Section 1: Introduction VN-MATRIX User Guide
Multicast RTP
This method uses a real-time variation of UDP (User Datagram Protocol), called RTP (Real Time
Protocol). Multicast RTP allows a source to be displayed on any number of displays.
.
The source encoder uses RTP to send data to a multicast group. The source does not need to know
the IP address of any decoders that use that source.
RTP provides very low latency which is important for video transport. Unlike other protocols, RTP
packets include a time-stamp. Therefore, if packets are received in the wrong order they can easily be
sorted into the correct order for display, or discarded if the time stamp is ‘out of date’.
However, because RTP is a connection-less protocol, data delivery is not guaranteed. Where data
packets are lost (e.g. due to excessive network traffic) VN-MATRIX carefully manages the data
stream to minimize any image disruption.
Page 16 I458GB issue 6
VN-MATRIX User Guide Section 1: Introduction
Unicast RTP
Like Multicast RTP this method uses a real-time variation of UDP protocol, called RTP. This method
can be used where the network infrastructure does not support multicast traffic. Typically this should
be used as a point-to-point configuration (i.e. single source to single display) but can be used for up to
four displays.
The source encoder defines the display decoder(s) that the source is available to, but the decoder
chooses which source to display.
RTP provides very low latency which is important for video transport. Unlike other protocols, RTP
packets include a time-stamp. Therefore, if packets are received in the wrong order they can easily be
sorted into the correct order for display, or discarded if the time stamp is ‘out of date’.
However, because RTP is a connection-less protocol, data delivery is not guaranteed. Where data
packets are lost (e.g. due to excessive network traffic) VN-MATRIX carefully manages the data
stream to minimize any image disruption.
I458GB issue 6 Page 17
Section 1: Introduction VN-MATRIX User Guide
Unicast TCP
This method transports data using standard TCP (Transport Control Protocol) and should only ever be
used for single point-to-point transfer of data.
TCP is a connection-based protocol and, therefore, data is guaranteed to be delivered. However, in
the event of excessive network traffic, delivery may be delayed which will impact on real-time
performance.
The decoder defines which source to ‘connect to’. Other than defining an IP Address and source type
(if required) no special source encoder setup required.
NOTE: Multiple decoder connections are theoretically possible using this method but NOT
recommended. Each additional connection will create extra loading on the encoder CPU which will
ultimately result in poor display performance. In addition, multiple TCP streams carrying the same
source data is an inefficient use of network bandwidth.

Environmental Requirements
CAUTION
The criteria on this page must be observed for all installations of the VN-MATRIX,
whether free-standing or rack-mounted.
Orientation
The VN-MATRIX is designed to be used free-standing on a stable, horizontal surface. It can, however,
be used in any orientation subject to the necessary ventilation requirements.
Temperature
DO NOT install or operate the VN-MATRIX in an area where the ambient temperature exceeds 35°C
(95°F) or falls below 5°C (35°F).
Remember that, as with all electronic equipment, the VN-MATRIX and its associated PSU also
produces heat which may affect the ambient temperature.
After the VN-MATRIX has been in use for a period of time the external casing may become slightly
warm to the touch. Ensure that any adjacent surfaces will not be affected by the heat.
Ventilation
DO NOT obstruct the ventilation grilles during use. The VN-MATRIX has an integral forced-air cooling
system. A fan draws air in through the grille in the front panel and expels ‘warmed’ air through the
grilles in the back panel. The fan speed is controlled automatically by an internal temperature sensor.
The fan may, therefore, appear to run faster as the unit warms up or if the ambient temperature is
increased.
A self-resetting thermal cut-out will shutdown the VN-MATRIX if the temperature exceeds design
limits.
Humidity & Water
DO NOT install or operate the VN-MATRIX in an area in which the ambient relative humidity exceeds
85% or in an area that is prone to condensation.
DO NOT install or operate the VN-MATRIX near water or in a location which may be prone to water
seepage — the VN-MATRIX is not waterproof.

Rack-mount Requirements
CAUTION
For rack-mounted installations, the following criteria must be observed (in addition to
the Environmental Requirements listed on page 25)
Mounting & Support
ALWAYS use the special rack-mount kits (available separately) to secure the VN-MATRIX. Full
details on using the kit are included with the kit. It will be necessary to remove the four feet prior to
rack mounting.
DO NOT stand other units directly on top of the VN-MATRIX when it is rack-mounted as this will place
excessive strain on the mounting brackets.
Ventilation
ALWAYS ensure that the rack enclosure is adequately ventilated. Sufficient airflow must be achieved
(by convection or forced-air cooling) to satisfy the ventilation requirements of all items of equipment
installed within the rack.
No additional ventilation gap is required above or below the VN-MATRIX and adjacent surfaces or
equipment.
Mains Supply
ALWAYS ensure that the mains power supply is of the correct voltage and frequency for all
equipment within the rack, and that it has a good ground/earth connection.
Where a power strip (mains distribution batten) is used (of either a hard-wired or plug and socket
type), always ensure that the current rating of both the power strip and the supply is sufficient for all
equipment within the rack.

VN-MATRIX User Guide Section 2: Installation & Basic Setup Procedures
Mains Power Connection (via PSU)
The VN-MATRIX must be powered from a 12 Volt DC regulated supply. A suitable mains-operated
power supply unit (PSU) is provided. The mains connection details that follow relate to the PSU.
NEVER CONNECT THE VN-MATRIX DIRECTLY TO THE MAINS.
To ensure CE compliance ALWAYS use the PSU provided.
If a backup/replacement PSU is required, always use an Electrosonic
approved PSU.
Supply Requirements (for PSU)
ALWAYS observe the following instructions to ensure safe and reliable
operation of the PSU.
ALWAYS ensure that the mains supply voltage is single phase only and is within the permitted range:
100 – 240V AC (0.45A Max.) 50 – 60Hz.
NEVER connect the PSU to a DC supply.
DO NOT allow the mains power point to be overloaded. This is particularly important to check when
powering several items of equipment from a single power point (e.g. within rack-mounted
installations).
WARNING: THIS EQUIPMENT MUST BE GROUNDED / EARTHED.
WARNING: To avoid the possible risk of electric shock or product damage due to condensation,
ALWAYS allow the PSU to become acclimatized to ambient temperature and humidity for at least
thirty minutes BEFORE switching on. This is particularly important when moving the unit from a cold
to a warm location.

Mains Power Cord (for PSU)
The mains PSU is equipped with a 3-pin (male) type mains connector which requires a power cord
fitted with a corresponding 3-pin IEC320 (female) connector.
Two power cords are supplied with the PSU, each having a different termination; you must use the
lead appropriate for your country:

Power-up Procedure
You must always ensure that the VN-MATRIX is powered-up at the same time as the source
computer or slightly before.
Powering the VN-MATRIX after the source computer may result in the source computer not correctly
detecting the mouse, keyboard and/or monitor.

VN-MATRIX User Guide Section 2: Installation & Basic Setup Procedures
Fitting a Mains Plug
If you are fitting a plug to the unterminated power cord (or replacing an existing plug), you must fit a
plug that:
• is rated for use with mains voltage
• is equipped with a grounding pin/connection
• complies with any applicable National or Local electrical regulations.
• is fitted with a correctly rated fuse (applicable to UK-style plugs only – see page 30.)
WARNING: Never attempt to fit or use a plug without a ground or earth pin/connection.
Wiring Details
The wires of both mains power cords (supplied with each VN-MATRIX) are color-coded as shown in

External Supply Protection
The mains power cord supplied with this product is rated at 10A maximum and
must be protected from overload by an external fuse or circuit breaker.
Fused Plugs (UK-style)
If the power cord is fitted with a UK-style BS1363 3-pin plug (i.e. with provision for an internal fuse),
then it must be fitted with a BS1362 ASTA approved 1 inch cartridge fuse.
This fuse must be rated at a maximum of 10A/250V. Since the current draw of the PSU is less than
1A, a fuse of a lower rating not less that 3A/250V may be used.
WARNING: Never attempt to fit a fuse or circuit breaker of a higher maximum rating than shown
above.
Unfused Plugs or Hard-wired
If the power cord is fitted with an unfused plug, or is hard-wired into a power strip (mains distribution
batten), then the power cord must be protected by an external fuse or circuit breaker of a rating shown
in the table below:
Supply Voltage
Maximum Fuse Rating 10A 10A
Minimum Fuse Rating 3A 3A
WARNING: Never attempt to fit a fuse or circuit breaker of a higher
maximum rating than shown above.
