About this Guide

The VN‑Matrix 250 (VNM 250) series consists of the VNE 250 encoder and the VND 250
decoder. This guide contains installation, configuration, and operating information for both
the encoder and the decoder.

In this guide:

z The term "encoder" refers specifically to the VNE 250 encoder.

z The term "decoder" refers specifically to the VND 250 decoder.

z The term "stream" refers to multimedia that is constantly received by (and normally

presented to) an end‑user while being delivered by a VN‑Matrix encoding device.

About the VNM 250

The VNE 250 distributes video, audio, and data input across an IP network to one or
more VND 250 decoders. Transport across the network must be coordinated by a
control device. For a small system (ten devices or fewer connected to the network) the
controller can be another VNM 250 (either an encoder or a decoder). For larger systems,
aVNMEnterpriseController is required.

The VNE 250 encodes video, audio, and data inputs into PURE3 data streams for transport
across a local area or wide area network. Elsewhere on the network one or more VND 250
units decode the stream.

VNE 250 inputs can include:

z Analog (VGA) video

z Digital (HDMI) video

z Analog audio

z Digital audio that is contained in an HDMI signal.

z Serial (RS‑232) and UDP data

z USB connections for remote mouse and keyboard

The individual video, audio, and data streams are synchronized and treated as a single
logical stream.

VNM 250 • Introduction 1

The VNM 250 series also supports a reverse audio channel for collaborative applications
where 2‑way communication is required.

The VND 250 video output is available only in digital format. It can be configured to display
at the same resolution and refresh rate as the encoder input or it can be scaled to match the
requirements of the display attached to the decoder.

The decoder supports both digital audio, analog audio, or both. The audio output is
independent of the encoder audio source.

UDP network data originating from an external source is streamed along with the video and
audio content to the appropriate decoder, where it is extracted for onward processing.

RS‑232 pass‑through data transport is full duplex. It can originate at either the encoder or
decoder and may be sent to multiple destinations. It passes through the system unchanged
and may not be recorded.

Figure 1 shows a typical application for the VNM 250.

VNM 250 • Introduction 2

VNM 250 System Controller

All Matrix systems require one device that acts as the system controller. For small systems
(ten devices or fewer), this can be either a VNE 250 or VND 250. For larger systems, a
VN‑Matrix Enterprise Controller must be used.

Systems Controlled by

VNMEnterpriseController

The VNM Enterprise Controller is able to
control all VN‑Matrix systems (large and small)
but is required for large systems (more than
10 devices).

The system is controlled through a powerful
web‑based user interface served from the
Enterprise Controller.

Supports all VN‑Matrix devices, including
recorders.

NOTES:

• A small system that includes a VNM 250 device must be controlled by either a

VNMEnterprise Controller or a VNM 250 device.

• If an incompatible VN‑Matrix device is added to a small system controlled by a

VNM250 device, the controller is unable to detect or control that device.

Transport Protocols Used for Streaming

The source data from a VN‑Matrix encoder can be distributed to multiple displays/decoders
(one‑to‑many) or to a single display/decoder (point‑to‑point). A previously recorded stream
can be distributed in the same way and may be thought of as an encoder in this context.

A stream may be transported from the source (encoder, recorded stream) to the display
(decoder) using one of three methods:

z See Multicast Real-time Transport Protocol (RTP) on page 4.

z See Unicast Real-time Transport Protocol (RTP) on page 5.

z See Transmission Control Protocol (TCP) on page 5.

Systems Controlled by

VNM250Device

A VNM 250 device can control small systems
(10 devices or fewer). It is less effective as the
system size increases.

The system is controlled through a more
limited web‑based user interface served from
the VNM250 controller device.

Supports VNM 250 encoders and decoders
and PCs running the VNS 104 software
decoder. Does not support recorders.

Multicast RTP — An Overview

DISPLAYS

Encoder sends data using

Multicast RTP allows a source to be displayed on multiple displays. This method uses a
real‑time variation of UDP (User Datagram Protocol) called RTP (Real‑time Transport
Protocol).

Figure 2. Multicast RTP Streaming

The source encoder uses RTP to send data to a multicast group. The source does not need
to know the IP address of the decoders that are using the source.

RTP provides very low latency which is important for video streaming. Unlike other
protocols, RTP packets include a time stamp. If packets are received in the wrong
order, they are sorted into the correct order for display or discarded if the time stamp is
out‑of‑date.

However, because RTP is a connectionless protocol, data delivery is not guaranteed.
When data packets are lost (for example, due to excessive network traffic), the
VNM 250 devices carefully manage the data stream to minimize any image disruption.

VNM 250 • Introduction 4

Unicast RTP — An Overview

DISPLAYS

SOURCE

DISPLAY

Encode

Similar to multicast RTP, this method uses a real‑time variation of UDP protocol, called
unicast RTP. This method can be used where the network infrastructure does not support
multicast traffic. Typically, this protocol is used for point‑to‑point configuration (single source
to single display), but can be configured to use up to a maximum of four displays.

NOTE: The encoder sends an individual stream to each decoder. This means that the

total bandwidth of the VN‑Matrix system increases as more decoders are added.

Figure 3. Unicast RTP Streaming

RTP provides very low latency which is important for video streaming. Unlike other
protocols, RTP packets include a time stamp. If packets are received in the wrong
order, they are sorted into the correct order for display or discarded if the time stamp is
out‑of‑date.

However, because RTP is a connectionless protocol, data delivery is not guaranteed.
When data packets are lost (for example, due to excessive network traffic), the
VNM 250 devices carefully manage the data stream to minimize image disruption.

TCP — An Overview

This method transports data using standard TCP (Transmission Control Protocol) and
should only 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
impacts real‑time performance. Therefore, TCP transport should be avoided for streaming
applications.

VNM 250 • Introduction 5

Definitions

PURE3 — is specifically designed for network transmission of real time media (such as
video or graphics, audio, data, and whiteboard elements). It features both spatial and
temporal image compression, which allows for efficient bandwidth usage.

z PURE3 streams always contain video or graphic elements.

z PURE3 streams may also contain audio and data content that is associated with the

video and graphic elements.

Media (stream) — refers to multimedia that is constantly received by (and normally
presented to) an end‑user while being delivered by a streaming provider. Internet television
is a commonly streamed medium. Streaming media (stream) in this guide refers to a PURE3
media stream that is produced by a VN‑Matrix encoding device.

Device license — refers to the number of licensed features that are available on a device
within a VN‑Matrix system. All devices contain a license that offers a default level of
functionality. Device licenses cannot be modified.

Controller license — refers to the license that is set on the device designated as the
system controller. The Controller license enables the use of VN‑Matrix software decoders.
Controller licenses may be modified to suit changing system requirements.

UDP data — refers to the transfer of serial data between an encoder and a decoder. Data
input is created at the encoder, placed into the PURE3 stream, and sent to the decoder. The
data is received in the same form that it was transmitted. This method of data transfer is
unidirectional and can only be sent from an encoder to a decoder.

High-Level Interface (HLI) — is the command protocol that is used to communicate
between the VNM Enterprise Controller and an external control system.

Display Monitor Timings (DMT) — a list of VESA standard pre‑defined timings which are
commonly used within the computer industry.

Coordinated Video Timings (CVT) — the newest VESA standard for generating display
timings (released on March 2003).

Generalized Timing Formula (GTF) — a method of generating industry standard timings
used by a wide variety of display products.

Features

Stream at native resolutions up to 1920x1200 and 2048x1080 — compatible with
signals used in high‑resolution display applications.

Low latency streaming — 35 ms encode and 35 ms decode — Supports natural
interaction, bi‑directional communication, or remote device control in real‑time operating
environments.

SFP port for use with optical Ethernet transceivers — provides the option to use an
optical Ethernet network interface to optically isolate a source or eliminate electro‑magnetic
emissions in secure applications.

Extensive bit rate management — uses compression and bit rate management controls
to tune image quality and bit rate to fit a variety of application and network requirements.

High immunity to network errors — AV streaming maintains reliable, high quality imagery,
concealing errors even during heavy packet loss.

Unicast or multicast streaming — supports scalability and compatibility with different
network operating conditions.

PURE3 Codec — low‑latency, visually lossless compression offering efficient bit rates, and
high immunity to network errors for streaming very high quality video with low delay over IP
networks.

VNM 250 • Introduction 6

Synchronization of multiple streams of audio, video, or both — audio and video

timing is maintained from a source across encoders preserving lip sync quality and
supporting multi‑source streaming applications.

Decoder genlock connection for synchronized decoding — supports synchronized
decoding of source streams across multiple VND 250 decoders.

EDID emulation — provides selectable resolutions and refresh rates, ensuring optimal
resolution and format between video sources, encoders or decoders, and displays.

Auto-Image setup — when activated, the unit automatically detects the resolution of
the incoming video signal and sets the total pixels, active pixels, and active lines, as well
as the horizontal and vertical starting points. This can save time and effort in setting up a
newly connected source, particularly in presentation environments where the input is not
connected to a fixed source, but instead goes to an open connection for a presenter’s
laptop.

Decode at native resolution or scale to match display resolution — configure
decoders to output the original source resolution or to scale incoming streams to match the
display resolution and maintain clean switches when new source streams are selected.

Aspect ratio control — the aspect ratio of the decoder output can be controlled by
selecting a FILL mode, which provides a full screen output, or a FOLLOW mode, which
preserves the original aspect ratio of the original source signal.

HDMI compliant — both the encoder and decoder support RGB and YCrCb source
formats.

HDCP compliant streaming — supports streaming of HDCP‑encrypted signals commonly
used in AV environments.

Key Minder continuously verifies HDCP compliance — authenticates and maintains
continuous HDCP encryption from sources to encoders and decoders to displays ensuring
reliable streaming of HDCP compliant displays.

HDCP Visual Confirmation provides a green signal when encrypted content is sent
to a non-compliant display — a full‑screen green signal is sent when HDCP‑encrypted

content is transmitted to a non‑HDCP compliant display, providing immediate visual
confirmation that protected content cannot be viewed on the display.

Audio —the VNM 250 incorporates:

z Bi‑directional audio streaming. Two‑way audio streaming supports bi‑directional audio

communication between encoders and decoders.

z HDMI embedded audio and analog stereo encoder inputs.

z HDMI audio embedding or de‑embedding by decoder. Audio signals can be embedded

onto the HDMI output signal or extracted to the analog stereo output.

z Audio breakaway streaming. Stream audio to decoders independently of associated

video sources. (This feature requires a VNM Enterprise Controller.)

Alarm relay — provides contact closure notice of warnings or alarms to control systems for
proactive system monitoring and fault resolution.

Front panel LCD interface, buttons, and rotary encoders — provide access and
control over device status and system data, simplifying system setup and operation.

Front panel LEDs — offers quick visual indication of device, system, or streaming status to
simplify commissioning activities and troubleshooting.

VLAN Tagging — simplifies management of encoders and decoders, making management
and operation on multi‑purpose networks simple.

Local Ethernet control port — offers the flexibility to connect a control device to the
VN‑Matrix 250 unit simplifying network cabling for the streaming system.

VNM 250 • Introduction 7

USB connectors for configuration — a USB mini‑B port on the front panel can be

connected to a local PC for low level configuration.

USB Keyboard and Mouse streaming — rear panel USB connections are provided to
allow for KVM type collaboration between an encoder and decoder pair. The encoder USB
ports allow connection to a local PC, while the decoder USB ports allow connection of a
mouse and keyboard to remotely control a PC connected to the encoder.

On-screen display — aids in identifying system connections and simplifies troubleshooting
and programming activities.

System management with VNM Enterprise Controller — simplifies management and
control of systems with many VN‑Matrix devices.

Compatible and interoperable with VN-Matrix 200 and 225 models — preserves the
value of prior investment in VN‑Matrix products.

Serial RS-232 data streaming — manage RS‑232 serially controlled devices across
VN‑Matrix 250 connections.

Smart power management for encoder, decoder, source, and display operation —
configure encoder, decoder, or display to manage operation and sleep mode for continuous
operation or energy management, lowering heat, and saving energy and operating costs.

VNM 250 • Introduction 8

Installation Overview

This section provides an overview of the installation process. To set up the VNE 250 and
VND 250, follow these instructions and the instructions referenced by the links provided:

1. If required, install small form‑factor pluggable (SFP) connectors in the LAN 2 ports (see

Streaming Network on page16).

2. Select a suitable location and mount the VNM 250 devices (see Mounting on

page129). Depending on your system, there may be multiple locations and multiple
units at each location.

3. Power on the VNM 250 devices by connecting the provided power supplies (see

page14). Do not connect the devices to a network.

4. Decide which device will be the system controller. For large systems (more than

10devices, you must use a VN‑Matrix Enterprise Controller. To configure the system
using the Enterprise Controller, see the VN-Matrix Enterprise Controller User Guide at

www.extron.com).

For smaller systems, you may use the Enterprise Controller or a VNM250 unit as the
controller (see Low Level Device Configuration on page 24).

5. Connect the Control connectors of the rear panel Coms port (three poles of the 5‑pole

captive screw connector) to a control computer. Use DataViewer to configure the IP
addresses for both the control port and streaming port, the subnet mask, and gateway
for each unit (see Low Level Device Configuration on page 24).

ATTENTION: Prepare thoroughly before connecting or configuring the VNM250

for an existing network. Contact your network administrator to ensure you
have the correct network information for each device that is being added to the
network. Incorrect connection or configuration may disrupt the network.

NOTE: Extron recommends configuring the IP addresses through the Coms port

on the rear panel. Alternatively, it is possible to use SIS commands (through the
USB on the front panel) or the front panel menu.

6. Connect all the VNM 250 units to the network (see Network Connections on

page15).

NOTES:

• Ensure that the LAN 2 port is connected to the designated streaming

network.

• The control port is used with IP Link or third‑party control devices. A control

port connection is not required for normal operation of the VNM 250 unit.

7. Connect the video sources to the encoders and display equipment to the decoders (see

Video Connections on page 20).

VNM 250 • Installation Overview 9

8. Connect the audio sources to the encoders and the audio outputs to the decoders. If

required, connect the reverse audio input to the decoder and the reverse audio output
to the encoder (see Audio Connections on page 21).

NOTE: The reverse audio feature allows users at the decoder site to communicate

with users at the encoder site.

9. If required, connect USB cables to allow KVM Function. This allows users at the

decoder site to take control of the keyboard and mouse of the source computer at the
encoder site (see page 17).

10. If required, connect the encoder loop‑through video (see Video Connections on page

20) and audio (see Audio Connections on page 21) outputs.

11. If required, set up Genlock connections to synchronize the video streams to multiple

displays (see page 19).

12. Use a PC or laptop to access the web interface served by the controller.

For larger systems, see the VN-Matrix Enterprise Controller User Guide. For smaller
systems, see VNM 250 GUI Overview on page 33.

13. Configure the video and audio input and output properties for all the devices, using the

appropriate GUI web interface.

NOTE: Extron recommends configuring the audio and video connections through

the GUI web interface. Alternatively, it is possible to use the front panel menu.

SECTION A–A

2. Connect the AC power cord of the power supply

unit to a 110 or 220 VAC electrical source.

If it is necessary to wire the captive screw
connector, ensure the polarity of the wires is correct (see the figure to the right).

Ensure the wires are stripped correctly (see the attention and note boxes below).

ATTENTION:

• Always use a power supply provided by or specified by Extron. Use of an

unauthorized power supply voids all regulatory compliance certification and
may cause damage to the supply and the end product.

• Extron power supplies are certified to UL/CSA 60950‑1 and are classified as

LPS (Limited Power Source). Use of a non‑LPS or unlisted power supply will
void all regulatory compliance certification.

• This product is intended for use with a UL Listed power source marked

“Class2” or “LPS” and rated 12VDC, minimum 3.0 A.

• The power supply provided must only be used with a single VNM 250 device.

Never use it to power multiple devices.

• The power supply shall not be located in air handling spaces or in wall cavities.

The power supply is to be located within the same vicinity as the Extron AV
processing equipment in an ordinary location, Pollution Degree 2, secured to
the equipment rack within the dedicated closet, podium, or desk.

• The installation must always be in accordance with the applicable provisions of

National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16.

• The power supply shall not be permanently fixed to building structure or similar

structure.

• If a power strip is used, for example within rack‑mounted installations, ensure

that the current rating for the power strip and the supply is sufficient for all the
equipment within the rack.

• The length of the exposed wires in the stripping process is critical. The ideal

length is 3/16 inch (5 mm). If it is any longer, the exposed wires may touch,
causing a short circuit between them. If it is any shorter, the wires can be easily
pulled out even if tightly fastened by the captive screws.

STREAMING CONTROL

The VNM 250 series units have two separate network
connectors: one for the control network (LAN 1) and the
other for the streaming network (LAN 2). Each port has
its own IP address.

The control port (LAN 1) is not required for normal
operation. When necessary, this port may be used to
enable control by a third‑party control system.

The streaming port is the primary network connection.
All media and device communication is delivered over
this network link. To connect to the streaming network,
use either the rear panel LAN 2 RJ‑45 connector or SFP
(fiber optic) connector.

NOTE: By default, only the LAN 2 RJ‑45 connector is populated and available for use.

If an SFP connector is required, it must be purchased and installed by the user. When
installed, the SFP connector becomes the active port and the RJ‑45 connection is
inactive. Both of the LAN 2 ports share the same IP address.

Streaming network (LAN 2)

NOTE: The RJ‑45 and SFP streaming network connectors share the same IP address.

Only one connector can be active at any time. If the SFP cage is unpopulated, the
RJ‑45 connector is active. If the SFP cage is populated, it becomes active and the
RJ‑45 connector is inactive.

By default, the RJ‑45 port is the active streaming network connection and the SFP cage
(see figure 6,
unpopulated.

To use the RJ‑45 port (see figure 6, C on page 13 for the encoder or figure7,C on
page 13 for the decoder), connect this port to the network with a standard LAN cable.

If required, third‑party SFP connectors must be purchased separately. To install an SFP
connector, follow these points:

1. Choose a suitable SFP connector (most models are acceptable). Either singlemode

(1310 nm) or multi‑mode (850nm) modules can be used.

2. Power down the unit. In addition to being good safety practice, the unit needs to be

rebooted for the device to correctly recognize the SFP port. When a compatible SFP
module is installed, the SFP port becomes active and the RJ‑45 port is deactivated.

3. Connect a single mode or multi‑mode cable to the encoder (see figure 6, D on page

13), or decoder (see figure7,D on page 13).

To use a VNM 250 device as a controller:

1. Configure the network settings of the device that is to be used as the system controller

(see Low Level Device Configuration on page 24).

2. Connect the device to the network using the streaming LAN 2 port on the rear panel of

the encoder (see figure 6, C or D on page 13), or decoder (see figure7,C or D
on page 13).

3. Open a web browser on a control PC that is connected to the same network.

4. Type in the IP address of the streaming port of the VNM 250 device that was set as

system controller in step 1, above, and use the GUI to configure the system settings
(see Setting a VNM Device as the System Controller on page 27).

NOTE: To control larger systems (ten or more components), use a VN‑Matrix

EnterpriseController (see the VN-Matrix Enterprise Controller User Guide at

www.extron.com).

Control network (LAN 1)

The control port LAN 1 may be used for system control, using the HLI control protocol. A
touchpanel or similar control interface may be connected and configured to communicate
with the VNM Enterprise Controller to recall previously configured presets.

NOTE: This control method may only be used with a VN‑Matrix Enterprise Controller.

The HLI control protocol is not supported by the VNM 250 controller (see the
VN-Matrix Enterprise Controller User Guide at www.extron.com).

KVM function

KVM functionality permits remote collaboration between different endpoints on the network
by allowing a mouse and keyboard connected to the decoder to control a PC connected to
the encoder using the rear panel USB ports.

1. Connect a mouse and keyboard to the VND 250 rear panel USB

ports (see figure7,F on page 13).

2. Connect a PC to the VNE 250 rear panel USB port (see figure 6, E

on page 13). This connection passes the mouse and keyboard control
signals to the source PC.

3. If the system is controlled by a VNM Enterprise Controller, use the Enterprise Controller

GUI for configuring KVM functionality (see the VNM Enterprise Controller User Guide at

www.extron.com).

If a VNM 250 device is the system controller, use the GUI for that device to configure
KVM Functionality (see VNM 250 GUI Overview on page 33).

Both the encoder and decoder must be configured to allow KVM functionality, using
the Peripherals page of the web user interface of the device being used as system
controller (see Configuring KVM Functionality on page 89).

Once configured, the KVM mode is activated using a hot key sequence on the keyboard
that is connected to the decoder (see To activate a remote control session using

hot keys on page 89).

4. Configure the system so that the decoder is viewing the source PC.

NOTE: KVM is only available when there is an active video stream between the

encoder and decoder.

RS-232 pass-through

The Coms port on the rear panel of the encoder (see figure 6, R on page 13), or decoder
(see figure7,R on page 13) is used for RS‑232 pass‑through communications, allowing
a control device connected to one VNM 250 unit to control a remote device connected to a
second VNM250 unit.

Serial data received by one VNM 250 unit is transmitted over the network, using
TCP/IP, and then converted back to serial data at the target VNM 250 unit. Data flow is fully
bidirectional.

Units that are configured for this type of data flow are called pass-through groups:

z One device in each pass‑through group is designated as a server.

z One or more devices are connected as clients.

z There may be more than one pass‑through group in a system.

z A pass‑through group may consist of all encoders, all decoders, or a mixture of both.

z A device may be a server or client independently of whether it is an encoder or decoder

and independently of whether or not it is the system controller.

z Pass‑through data is not part of the media stream and cannot be stored by a

VN‑Matrixrecorder.

z Data passes through the system unchanged (transparently). No VNM 250 devices are

affected by the commands.

z The serial ports on different devices do not need to share a common baud rate.

However, if a large amount of data is sent from a high speed to a low speed data link,
some form of handshaking or flow control may be required to prevent buffer overflow on
the output device. Standard flow control methods are fully supported.

To set up the RS‑232 pass‑through group:

1. Decide which VNM 250 unit will be the server in the pass‑through group and which will

be the clients.

2. Connect your serial devices to the VNM 250 RS‑232 ports

accordingly. Communication can only take place between server
and client, not between clients.

Genlock

Genlock I/O (VND 250) —is used to synchronize the video output
on multiple decoders.

NOTE: The VND 250 uses TTL level signalling, which is not

compatible with normal genlock sources.

One decoder is selected as the reference (master) unit, and provides the signal that is used
to synchronize all the other units (slaves).

1. Configure one decoder as the Master unit, using the web‑based GUI control program

(see Genlock on page59).

2. Configure all the other decoders as slaves by selecting the Genlock check box of the

web‑based GUI control program (see page 59).

3. Connect the Ground connector of the master unit to the ground connector of the first

slave device.

4. Connect the Out connector of the master unit to the In connector of the first slave

device.

System
Configuration with
the Enterprise
Controller

All Matrix systems require one device that acts as the system controller. For a small system
(ten devices or fewer), this can be either a VNE 250 or VND 250. For larger systems a
VN‑Matrix Enterprise Controller must be used.

A system controlled by the Enterprise Controller can incorporate any VN‑Matrix devices,
including recorders, into the system.

Systems controlled by a VNM 250 device cannot exceed 10 devices in total. A VNM250
controller supports VNM 250 encoders and decoders and PCs running the VNS104
software. It does not support recorders. If an incompatible VN‑Matrix device is added to a
system controlled by a VNM250 device, the controller cannot detect or control that device.

Controlling Your System with a VN-Matrix Enterprise Controller

1. Connect a PC and a VN‑Matrix Enterprise Controller to the same network as the

components of your streaming AV system.

NOTE: The PC and Enterprise Controller must be connected to the same network

as the streaming port (LAN 2) of the VNM 250 device.

2. Open an internet browser on the PC and enter the IP address of the VNM Enterprise

Controller in the address bar. The login screen opens.

Figure 9. VN-Matrix Enterprise Controller Login Page

3. Enter the Username and password.

NOTE: Check with your Network Administrator for the Username and password. If

they have not been changed from the default settings, the Username is admin (all
lower case) and there is no password (leave the box empty).
