About this Guide
This guide contains installation, configuration, and operating information for the Extron®
VN-Matrix® VNC 325 encoder/decoders (codecs).
NOTE: This guide describes the operation the VN-Matrix 325 with version 4.6 or later
firmware.
About the VNC 325 Codec
The VN-Matrix VNC 325 video codecs (see figure 1) distribute digital SD, HD-SDI, or 3G-SDI
broadcast quality video and audio content across an IP network using the Extron PURE3®
Codec algorithm. PURE3 exceeds many of the performance characteristics of existing
compression formats and provides exceptionally robust protection against network errors,
making it ideal for quality-critical applications. The VNC 325 codec 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 325 encoded data stream from a network.

Each VNC 325 codec has an integrated web interface. One codec in the VN-Matrix system
must be designated as the system controller, and the controller can be any unit in the
system, whether it is configured as an encoder or decoder. All normal system configuration
and control is via the web interface of the designated controller. Using a computer on the
same network and a standard web browser, such as Mozilla® Firefox® or Microsoft® Internet
Explorer®, you can configure any VNC 325 unit in the system.
Video signals that are connected to a VNC 325 codec that is configured as an encoder are
compressed into a data stream for transport across a local area or wide area network. At the
far end of the network, one or more VNC 325 codecs configured as decoders decode the
compressed stream back into the original video signal format.
The VNC 325 that is configured as an encoder accepts audio that is embedded in the input
video and that complies with the following SMPTE standards:
• SMPTE 299M — 24-bit digital audio
• SMPTE 272M-A — 20-bit digital audio
The embedded audio groups can be transported with the associated video content. Audio
can be sent as received (transparent mode) or as a single stereo pair (stereo mode). Stereo
mode results in a lower bit rate and reduces the network load. The VN-Matrix system also
supports simple compression of the stereo audio.
A dedicated RS-232 port is available for distributing RS-232 data with the coded/decoded
video, such as for control of projector.
A VN-Matrix 325 system is comprised of 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 can display the source provided by any
encoder. Figure 1, on the preceding page, shows a basic VN-Matrix 325 system. In this
example, either of the two encoder streams can be routed to any or all three decoder units.
The configuration of each device, including the source that is displayed at each destination,
can be set using any PC or laptop on the same network, using the VN-Matrix 325 web
pages. In this example, the codec that is labeled IP Decoder 3 is the system controller.
Source (digital video) data from a VNC 325 encoder can be distributed to multiple decoders
and displays (one-to-many) or to a single decoder and display (point-to-point). Video data is
transported from the source (encoder) to the display (decoder) using one of three methods:
• Multicast real time protocol (RTP) — One source (encoder) and an infinite number of
displays (decoders)
• Unicast RTP — Single source (encoder) to single display (decoder), but it can also be
used for up to four displays
• Unicast transport control protocol (TCP) — Single source (encoder) to single display
(decoder). This method should be used only for single point-to-point transfer of data.
Each method, with its advantages and disadvantages and a sample connection diagram, is
described in “Data Transport Methods” in the “Installation“ section.
The units are housed in 1U high metal enclosures that can be mounted in any standard
19-inch rack or under furniture with optional mounting kits.
The external 100 VAC to 240 VAC, 50-60 Hz power supply provides worldwide power
compatibility.

Autodetection — The codecs auto-detect the format of the connected signal. Input sources
are encoded and decoded at their native resolution and format
Audio signal compatability — The codecs support the transport of embedded audio input
data, as described by the SMPTE 299M 24-bit digital audio and SMPTE 272M-A 20-bit digital
audio standards.
Configurable as encoder and decoder —
Encoder signal connections — The unit has three functional BNC connectors for video
connections; an input and two looped outputs.
Decoder signal connections — The unit has two functional BNC connectors for video
and sync connections.
Two levels of operator interface —
Low-level configuration — The Ethernet parameters of each codec in the system are
set using a PC connected to an RS-232 serial port.
Final configuration and operation — After the initial low-level configuration, all
other configuration and operation of the VN-Matrix 325 system is via either of two
Ethernet ports of the system controller unit. A computer that is running on the same
network as either port can control the entire system using the built-in HTML pages of
that unit.
System control — One codec unit in the system is designated as the system controller. The
unit acts as a server for the HTML control interface and holds a record of the configuration
of all VN-Matrix 325 devices on the network. The system controller manages the
communications to all VNC 325 devices. Any codec, whether it is configured as an encoder
or decoder, can be used as the system controller.
Two Ethernet ports — Each unit has two Ethernet ports for network connections:
One RJ-45 port for a Category (CAT) 6 twisted pair (TP) cable
One optical port for a fiber-optic cable
Two RS-232 serial ports —
Remote port — For low-level configuration of the Ethernet parameters of the unit.
RS-232 Over LAN port — For inputting and outputting RS-232 data with the coded
and decoded video, such as for control of projector. This port is also for access to the
built-in alarm relay.

VN-Matrix 325 Serial Digital Over IP CODEC • Introduction 3
Highly efficient compression algorithms — The VN-Matrix 325 system uses a minimal
amount of data to transport video and audio across the network.
NOTE: It is crucial to the effective operation of VN-Matrix 325 that sufficient data
throughput be achieved, especially where multiple sources are encoded.
The network efficiency is directly affected by the speed and configuration of
each element, such as switchers and routers, within its infrastructure. The
VN-Matrix 325 system achieves optimum transmission results over a dedicated
1 Gbps network (1000Base-T, also known as Gigabit Ethernet).
Rack mounting — One or two 1U high, half-rack metal enclosure units can be mounted in
any standard 19-inch rack with optional mounting kits.
Under furniture mounting — Using optional Extron surface mount kit
Power — The external 100 VAC to 240 VAC, 50-60 Hz power supply provides worldwide
power compatibility.

Data Transport Methods
l
IP Decoder 1
Source (video) data from a VNC 325 encoder can be distributed to multiple decoders and
displays (one-to-many) or to a single decoder and display (point-to-point). Video data is
transported from the source (encoder) to the display (decoder) using one of three methods,
in order of preference, which are detailed in the following sections:
• Multicast real-time protocol (RTP) — Best choice
• Unicast RTP — Second choice
• Unicast Transport Control Protocol (TCP) — Acceptable
You need to select among these three methods using the HTML pages, see “Configure
Encoders or Decoders“ on page 25.
Multicast RTP
The multicast real-time protocol (RTP) data transport method is connected as shown in
figure 3. Multicast RTP is a one-to-many protocol that allows a source to be displayed on
an infinite number of displays. This transport method uses a real-time variation of User
Datagram Protocol (UDP), called RTP. In figure 3, the streaming data is identified as “RTPm”.

Figure 3. Typical Multicast RTP Application
NOTES: • The UDP protocol is a standard Internet network protocol that is connection-
less, meaning that it does not use the hand-shaking that provide reliability,
ordering, or data integrity but is overhead intensive. Therefore, UDP can
be unreliable. On the other hand, RTP provides very low latency, which is
important for video transport.
• The VN-Matrix 325 supports IGMP V2 for multicast streaming.
VN-Matrix 325 Serial Digital Over IP CODEC • Installation and Setup 8
This is the recommended transport method for real time video and audio data over an
S
IP Decoder 1
IP network. However, because RTP is a connection-less protocol, data delivery is not
guaranteed. Where data packets are lost (such as due to excessive network traffic), the
PURE3 algorithm carefully manages the data stream to minimize any image disruption.
NOTE: In figure 3, IP decoder 3 is designated as the system controller.
Unicast RTP
Like multicast RTP, the unicast RTP data transport method uses a real-time variation of the
UDP protocol that is connected as shown in figure 4. Unicast RTP differs from multicast RTP
in that it is a point-to-point protocol that uses a separate data stream for each decoded
display. The VN-Matrix 325 system can support up to four displays (decoders) from one
source (encoder), but such a configuration uses four separate data streams and results in
four times the network bit rate as a single display (decoder) configuration.
This method can be used in place of multicast RTP, when the network infrastructure does
not support or the local IT administration will not allow multicast traffic. Contact the system
administrator.
In figure 4, the four streams of data are identified as “RTP1” through “RTP4”.

Figure 4. Typical Unicast RTP Application
As with multicast RTP, it is a connection-less protocol and data delivery is not guaranteed
Where data packets are lost (such as due to excessive network traffic), the PURE3 algorithm
carefully manages the data stream to minimize any image disruption.
NOTES: • In figure 4, the IP encoder is designated as the system controller.
• In unicast RTP mode, while the system supports up to 4 simultaneous
streams, the rate is dependant on the total aggregated bit rate, which must
not exceed 270 Mbs.

Unicast TCP
l
Control
Each encoder is ‘paired’ to a decoder
The unicast TCP data transport method uses standard TCP protocol and should be used for
single point-to-point transfer of data only. This method is connected as shown in figure 5.
NOTES: • Multiple decoder connections are theoretically possible using this method
but not recommended. Each additional connection creates extra loading on
the encoder CPU, which ultimately results in poor display performance. In
addition, multiple TCP streams carrying the same source data is an inefficient
use of network bandwidth.
• While figure 5 shows two decoders, in the scenario shown only IP decoder 1
is set to actively decode data that is streamed to it. IP decoder 2 may be
in standby (set as Device Type: None, see “Configure Encoders or
Decoders“) or may be receiving streamed data from another encoder.
• In figure 5, IP decoder 2 is designated as the system controller.

TCP is a connection-based protocol. Data is guaranteed to be delivered, however excessive
network traffic, which impacts real-time performance, may delay delivery.
Data and Control Routing
The system can be used over both switched (single segment) and routed (multi-segment)
networks
The VN-Matrix 325 system can be configured to run using either a single LAN port (1 or 2)
or both LAN ports. In the single port configuration, all data (image, audio, control, and
monitoring) is transported on the designated port. In the dual port configuration, image and
audio data is transported on one connection while the other LAN port is used for monitoring
and or management functions.
All system control is managed by the VNC 325 that has been designated as the controller.
Any changes made in the network browser are sent to the affected codec from the
controller via the network that has been assigned for streaming. The browser is accessible
via either network port on the unit that is configured as the controller.
Video and audio data can be transported over either of the LAN ports on the VNC 325 and
are independent of the system control data.

Example 1: Switched and isolated network configuration
NOTE: It is immaterial, in this example, which codec is the encoder and which is the
decoder. These functions are not identified in figure 6.
Figure 6 shows two VNC 325 codecs that are configured to work across two switched and
isolated networks. Codec 1 is configured as the controller, via LAN port 1. The controller
handles all normal system configuration and control via its web interface.
This example consists of two networks, connected to the VN-Matrix system as follows:
• Network 1, connected to LAN port 1 (RJ-45 port), the “green” network — The
encoder streams video on this network and it is also used for system control and
monitoring.
NOTE: Selection of this network for streaming is via the built-in HTML network
interface. This selection is defined in the management interface, described
later (see “Configure Encoders or Decoders“).
• Network 2, connected to LAN port 2 (the fiber optic port), the “red” network —
This network is separated from the streaming network. This network also can be used
for system control and monitoring if preferred.
NOTE: The controller codec responds to inquiries on LAN port 2 as well as LAN
port 1.
• A network management server can also be integrated if required.

• The gateway IP addresses (the addresses on both sides of the router on the red network)
is set on LAN port 2 (configuration option 14) for both codecs.
• This architecture provides isolation between the video transport and simple network
management protocol (SNMP) traffic.

VN-Matrix 325 Serial Digital Over IP CODEC • Installation and Setup 16
Low-level Network Configuration
REMOTE
Before connecting a LAN port (see item d or item e on figure 2 and on page 6) on any
VNC 325 to the network, you need to establish the network settings of each unit.
You also need to select one codec in the VN-Matrix system as the controller and designate
that codec, by its IP address, in each codec. All normal system configuration and control is
via the network interface for the designated controller, which functions as the server for the
VN-Matrix. The controller can be any unit in the system, whether configured as an encoder
or decoder.
In a typical installation, you need to enter the following settings for each codec:
• The IP address of the codec
• The subnet mask (netmask) of the codec
• For a network that is dedicated exclusively to the VN-Matrix, which is
the preferred setup, Extron recommends that you use addresses in the range
of 192.168.0.1 through 192.168.0.254, with a subnet mask (netmask) of
255.255.255.0.
• For an open network, contact the system administrator for a range of IP addresses.
• The IP address of the codec that is selected as the controller
NOTES: • You need to manually assign a known IP address for the controller into each
codec in the VN-Matrix. This allows each VN-Matrix 325 device in the system
to be set to recognize the IP address of the device controller.
• Because Dynamic Host Configuration Protocol (DHCP) can change IP
addresses, it is not practical to use this protocol. Extron recommends that you
use a static IP address scheme.
Change the network settings for all units as follows:
1. Connect a null modem serial cable from the serial port of a computer
to the Remote port (see item a on figure 2 and on page 6) on the
VNC 325 to be configured.
2. On the PC, run a terminal emulation program such as the Extron
DataViewer utility or the HyperTerminal utility. The RS-232 protocol for the Remote port
is as follows:
Baud rate: 115200 Data bits: 8 Parity: None
Stop bits: 1 Flow control: None
3. Connect the power to the VNC 325 (see item c on figure 2 and on page 6).
The VNC 325 sends setup and diagnostic data, which appears in the terminal emulator
window. After a few seconds the diagnostic data stops and the terminal emulator
displays a flashing cursor.
4. Press the keyboard <Enter> key.
The VNC 325 responds with the following login prompt:
VN Matrix(R) Maintenance Console: ver n.n
192.168.0.1 login:
NOTE: The login prompt is preceded by the current IP Address of the unit,
192.168.0.1 in the example above.
5. Type the default login config and press <Enter>. The connected unit responds with the
prompt password:.

6. Type the default password config and press <Enter>. The connected unit downloads
the configuration menu (see figure 10).
NOTES: • The IP addresses and other variable shown in figure 10 are for illustration
only and may not match those on your unit.
• Many menu selections are not available if DHCP is selected. Select option
1 or 11 to toggle DHCP on and off.
