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.

VN-Matrix 325 Serial Digital Over IP CODEC • Introduction

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

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.

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”.

Any number of decoders can
be part of the multicast RTP group.
Figure 3. Typical Multicast RTP Application
NOTES: • The UDP protocol is a standard Internet network protocol that is connectionless, 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.

This is the recommended transport method for real time video and audio data over an
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”.

Up to four decoders can

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.
VN-Matrix 325 Serial Digital Over IP CODEC • Installation and Setup

Unicast TCP
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.
Each encoder is ‘paired’ to a decoder
with a point-to-point data link.

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.

Example 3: Routed 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 8.
Figure 8 shows an example of a routed network configuration. Codec 1 is configured as the
controller, via LAN port 2.
•
The two codecs are connected across a wide area network (WAN) via an external router.
•
Network 1, connected to LAN port 1 (RJ-45 port), the “green” network — This
network is separated from the streaming network. This is the primary network for
system control and monitoring.
•
Network 2, connected to LAN port 2 (the fiber optic port), the “red” network —
The encoder streams video on this network and it can also used for system control and
monitoring if desired.
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“).
•
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.
NOTE: The SNMP protocol includes a system of SNMP trap messages. SNMP trap
messages can be initiated by a network element and sent to the network
management system.

Low-level Network Configuration
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.
REMOTE
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
Stop bits: 1
Flow control: None
Parity: 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:.

Making Remaining Connections
RS-232 Over LAN Port
If you want the VN-Matrix units to pass serial data or control signals, such as for serial
control of a projector, connect RS-232 devices to RS-232 Over LAN port on all codecs that
are hosting controlled or controlling devices. Figure 11 shows how to connect a host device
to the pass-through device to the RS-232 Over LAN port (b on figure 2).
NOTE:
The RS-232 Over LAN port also connects relay contacts that turn on when a
critical alarm occurs. See “Filter settings panel“ to define a critical alarm.

Figure 11.Pin Assignment for the RS-232 Over LAN Port
NOTES: • The VNC 325 uses 9-pin D male connectors. You may need an adapter.
• The default RS-232 protocol for the RS-232 Over LAN ports are as follows:
Baud rate: 115200 Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
These parameters are configurable to agree with device to be controller (see
“Configuring a Serial Pass-through Group“ in the “Operation” section).
LAN Ports
NOTES: • The number of units that can be connected to the network, while still
providing optimal performance, varies depending on the data transport
method used. See “Data Transport Methods” on page 7 for details.
• Do NOT connect VN-Matrix units to an existing network until each is correctly
configured. Incorrect configuration may cause disruption to other network
users. See “Configuring Network Settings” to configure the units.
• Items d and e, below, are identified in figure 2 on page 6.

network.
NOTE:
The factory default IP address for this port is 192.168.0.1.

• The factory default IP address for this port is 192.168.1.2.
RJ-45 port wiring
It is vital that your Ethernet cables be the correct cable type and that they be properly
terminated with the correct pinout. Ethernet links use Category (CAT) 5e or CAT 6,
unshielded twisted pair (UTP) or shielded twisted pair (STP) cables, terminated with RJ-45
connectors. Ethernet cables are limited to a length of 328 feet (100 m).
NOTES: • 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).
• Do not use standard telephone cables. Telephone cables do not support
Gigabit Ethernet.
• Do not stretch or bend cables. Transmission errors can occur.
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application (see figure 12).

The VN-Matrix system supports two audio transport modes:
Transparent — The compression engine streams the selected audio data
exactly as embedded in the SDI/HDSDI/3G SDI format, with no processing. This mode
can result in a high bit rate.
Stereo — The compression engine extracts a single stereo pair (two channels) of audio
data and packs it into the data stream.
•
Channel pair selection (É)
Channel pair 1 — Selects group 1, channels 1 and 2.
Channel pair 2 — Selects group 1, channels 3 and 4.
Channel pair 3 — Selects group 2, channels 1 and 2.
Channel pair 4 — Selects group 2, channels 3 and 4.
Channel pair 5 — Selects group 3, channels 1 and 2.
Channel pair 6 — Selects group 3, channels 3 and 4.
Channel pair 7 — Selects group 4, channels 1 and 2
Channel pair 8 — Selects group 4, channels 3 and 4.
In Transparent mode, you can select from two to eight channel pairs; you cannot select
a single pair. In stereo mode, you can select only one channel pair.
The indicator to the right of the list showing each channel pair is green if that audio
group is present in the SDI source.

Forward error correction (FEC) panel
3a
3b
3c
Figure 28.Audio Encoder FEC Panel
NOTES: • FEC is only applied to the audio data channel; it is not applied to the video
channel.
• FEC is effective only for RTP transports. It should not be used for TCP
transport.
• FEC is not required, and is not applied when the encoder is configured in
stereo mode.
Forward error correction can be applied to the audio data in data streams that use the
RTP transport to protect audio data against data loss. Forward error correction enables the
decoder to recreate data that has been lost or corrupted without retransmission. FEC adds
additional data to the stream that the decoder can use to detect and reconstruct any lost
packets. The FEC data is sent separately from the image and audio data.
The level of FEC can be set to protect against different levels of data loss. This produces a
corresponding change in the amount of data that is transported and thus, the bit rate is
increased or decreased in proportion to the amount of FEC applied.
The VN-Matrix 325 products implement the recommendations defined by the PRo-MPEG
Code of Practice #3 (CoP3)/SMPTE 2022 standard.
Ñ FEC Mode — The FEC can be applied as either column only or row and
column.
•
Row FEC protects against the loss of a single packet. It is the
simplest method of protection and results in the lowest overhead in
terms of bit rate and latency. However, it cannot handle consecutive packet losses
(burst packet loss).
•
Column FEC protects against burst packet loss, providing that the burst of packet
losses are not in the same row. Since correction data is only calculated on one
dimension, column FEC is known as 1-dimensional (1-D) FEC.
By using both FEC methods together, 2-dimensional (2-D) FEC, the combined effect
protects against more loss combinations than either scheme by itself.

The chart at left shows the FEC scheme applied
to a 4 column x 5 row structure. This scheme
adds 5 row FEC packets (FR1 through FR5) and 4
column FEC (FC1 through FC4) packets to every
20 data packets. This scheme can protect for
burst packet losses up 5 packets long.

If packet P6 is lost or corrupted (x), the loss
can be corrected by using the FR2 FEC packet.
However, corrupt packets P14, P15, and P16
cannot be corrected using the row FEC packet
(FR4) because too much data is missing.
To correct these packets, the column FEC data is
used. Packets 15 and 16 can be corrected using
FC3 and FC4 column FEC packets. Before
correcting packet 14, packet 6 must first be corrected using the row FEC. After this,
the column FEC can be used to correct packet 14.
Ö Fec Rows and FEC Columns — Extron recommends a setting of 5 for rows and 5 for
columns, which should be the starting point for the error correction for the audio
transport and provides rugged operation on uncorrected IP networks.
The values that you set in the FEC row and column drop down lists depend on the
quality of the network link that is in use. The diagrams above show that the FEC data
can add large overhead to the overall bit rate transported over the network. Therefore
certain settings, while they may provide a high level of reliability, are inefficient.
Alternatively, settings that add little overhead may not provide a sufficient level of
protection on networks with a poor quality of service.
ñ Error Injection Rate — This setting should be left at 0. It used for test purposes only,
to drop packets artificially in order to test the effectiveness of the FEC scheme.
Streams panel
The audio encoder configuration page streams panel (see figure 29) provides details of any
active audio encoder streams. The data transport method, TCP or RTP, is defined on the
decoder configuration page (see “Configure Encoders or Decoders”). Audio multicasting
is selected in this panel (see “Enable multicast streaming“ to select the multicast and
“Data Transport Methods“ for definitions of the methods).
Figure 29.Audio Encoder Streams Panel
NOTE:
This setting does NOT track the same setting applied in other (video, anc,
colfec, and rowfec) encoder configuration pages. For most applications, you
should set the same transport for all stream elements, but this is not mandatory.
The New Export Stream function is not supported.
Configuration Page — Colfec and Rowfec Encoders
The colfec and row encoder configuration pages (see figure 30, on the next page)
provide the same basic function, enabling of multicasting. The encoder that you may
need to configure depends on whether you have selected column only (colfec encoder) or
and Row + column (rowfec encoder) as the FEC mode (see “Forward error correction
(FEC) panel“). The streams panel provides details of any active FEC encoder streams.
The data transport method, TCP or RTP, is defined on the decoder configuration page
(see “Configure Encoders or Decoders”). FEC multicasting is selected on this page

Figure 32.Bandwidth Management (Standard) Controls Panel
The Streams information area (Ä) provides statistics for any active streams currently running
from the encoder. The bit rate value is the total for all streams, including video, anc (audio)
and forward error correction.
Configuration for the encoder is made via three entries:
Å Control Mode — This drop down box is a set of four modes that apply
different spatial and temporal compression schemes to manage the
encoded image data stream.
NOTE:
These control modes are also accessible in the Advanced
settings panel.
•
None — The compression scheme maintains a constant image quality. The bit rate
varies dependant on the content. Slowly moving or static image content has a lower
bit rate than fast moving image sequences. There is no bit rate limiting in this mode.
•
Peak Flow (FD) — The spatial image quality is held constant, however, a bit rate
limit is applied. Controlling the frame update rate whenever the bit rate limit is
exceeded maintains the limit.
•
PBR-F — This is a peak bit rate mode. The spatial quality is held constant until the
bit rate limit is exceeded, at which point, additional spatial compression is applied to
keep the bit rate at the specified limit.
NOTE:
•
If you cannot maintain the bit rate limit using only spatial compression,
then you should choose a different control mode or increase the bit
rate limit.
PBR-F (FD) — This mode is similar to PBR-F with the addition of dynamic frame rate
management if the spatial compression is insufficient to maintain the bit rate limit.
û Image Quality — Image quality controls the spatial compression. A setting of 4
provides a visually lossless image. A higher setting results in higher compression
and lower bit rate for the encoded stream. A lower setting applies a lower level of
compression but a higher bit rate.
ü Bit rate — Enter a value of up to 300.000 Mbps to set the limit for the total bit rate
for all data; image, audio, and audio. This control is not available for editing when the
Control mode is set to None.

The panel is divided into to two main categories:
•
Video Quality (spatial compression) settings
•
Bandwidth settings
Video Quality Management
Ä Luminance — This control sets the level of luminance spatial compression, from 0
(minimum compression) to 10 (maximum compression).
Å Chrominance — This normally locked field shows the level of chrominance spatial
compression, from 0 (minimum compression) to 11 (maximum compression). When
locked, chrominance is directly related to the Luminance control by an offset value of 2.
NOTES: • To manually set the chrominance compression, uncheck the Lock
check box.
•A value of 2 is the optimal offset between luminance and chrominance.
•Settings of 4 (Luminance) and 6 (Chrominance) provide visually lossless
compression for HD content.
•By default, the offset between Luminance and Chrominance is set to 2
whenever the Advanced controls panel is hidden (the Bandwidth
Management controls panel Standard button is clicked).
û Temporal Compression mode check box — Applies temporal compression to the
bandwidth management, causing data to be transferred only when a change occurs
between frames. This box is selected by default and should always remain selected.
ü Refresh Rate — Controls how frequently the non-changing parts of the screen are
updated when temporal compression mode is enabled ( the Temporal Compression
check box is selected). This is useful when connecting new displays to a multicast source
and to fill in gaps in the data when using a lossy network transport such as RTP. A value
of 1 refreshes the screen in one second, a value of 0.1 refreshes the screen 10 times per
second. A value of 0 disables the refresh.
† Threshold — The threshold setting modifies the detection point of the temporal
compression algorithm. A value of 0 results in all changes between frames being sent.
As the threshold value is increased, only changes above a certain level are sent, thus
reducing the bit rate. As a general rule, always set this to a 1 for a camera originated
image.
VN-Matrix 325 Serial Digital Over IP CODEC • Operation
44
NOTE:
Threshold compensates for image sources that have a level of noise in
them. In general, there is always a certain amount of noise in any source
that is produced by an analog method. By applying a threshold, this noise
can effectively be ignored by the PURE3 compression engine, resulting in a
lower transmitted bit rate.
°Chroma check box — The Chroma setting adapts the temporal compression to note
the chroma changes in an image. When enabled, chroma thresholding increases the bit
rate. This setting should be selected for video sources.

ÄMode — This drop down box is a set of six modes that apply
different spatial and temporal compression schemes to manage the
encoded image data stream. See “Typical bit rates“ for suggested
mode selections.
NOTE:
Two of these control modes are available only from
this panel. Four are also accessible in the Bandwidth
Management controls panel settings panel.
•
Manual Frame Drop — In this mode, the spatial image quality is held constant.
However, the bit rate is managed by reducing the number of frames that are
transported. The frame rate is managed by setting a value for the Frame Drop
Percentage (see item û, below).
•
Shared Flowrate — This mode is the same as the Peak flow rate but the bit rate
control is applied to the aggregate value for all streams from the encoder, as would
be the case if multiple (maximum 4) Unicast RTP streams are chosen as the data
transport method.
•
None — See the Control mode drop-down box in “Bandwidth Management
standard controls panel.“
•
Peak Flow — See the Control mode drop-down box in “Bandwidth
Management standard controls panel.“
•
PBR-F — See the Control mode drop-down box in “Bandwidth Management
standard controls panel.“
•
PBR-F (FD) — See the Control mode drop-down box in “Bandwidth

Å Target Bandwidth (Mbps) — This value duplicates the Bit rate control in the
Bandwidth Management controls panel. Enter a value of up to 300.000 Mbps to set
the limit for the total bit rate for all data; image, audio, and audio. This control is not
available when the Control mode is set to either None or Manual Frame Drop.
û Frame Drop Percentage — This is the percentage of frames that are dropped
whenever the manual frame drop is the chosen control mode. See “Typical bit rates“
on the next page to see the estimated bit rates for various video, audio, and error
correction selections.

Typical bit rates
This section provides estimated bit rates for various video, audio, and error correction
selections and suggested mode (see “Bandwidth Management”, item Ä), selections.
The maximum supported bit rate is 300 Mbps, which is the total combined bit rate for

of the bandwidth management standard controls panel shows the total transport bit rate as
adjustments are made to compression and FEC.

The VN-Matrix 325 supports the transport of the audio data that is embedded in the video
transport. Audio is available in blocks of 4 channels, with a bit rate of 2.43Mbps per pair
in stereo mode. Forward error correction, which implements the recommendations defined
by PRO-MPEG COP3, can be added to the audio stream to correct for packet drops on the
network. Be aware, though, that forward error correction can add up to 50-percent to the
bit rate overhead.

NOTES: • The bit rate statistics reported on this page apply to the stream type you
selected. This display is different from the bit rate statistics reported by the
encoder, which is for the total of all stream types.
• This section is specific to the video data stream. Note that the scheme for
audio and error correction data is the same.
a Source: — Reports the currently select stream.
b rtp destination — Reports the IP destination address and port for the current stream.
When connecting using RTP this is either a multicast group address or, for RTP unicast,
the IP address of the decoder. When connecting using TCP, this field is displays 0.
c rtp source — Reports the multicast group address to which reception statistics are
reported. In RTP unicast and TCP modes this field reports the IP address of the encoder.
d Playback Delay field — Defines the playback delay, the sum of the transit time in the
network and the time spent in the input buffer of the decoder. You can modify this
setting. Use the PIpeline Status indicator (e) as a guideline for the correct value.
•
Setting the Playback Delay to too small a value can result in the decoder input
buffer emptying faster than data arrives (underflowing). The playback image jumps
as network loading changes occur.
•
Setting the Playback Delay to too large a value can result in the decoder input buffer
filling more quickly than data can be processed (overflowing). The increase in image
latency can result in an internal buffer overflow on high bandwidth data streams, a
jumpy screen update, and screen flashing.
The Playback Delay setting should be set to a value between 0.1 and 0.2 seconds.
e Pipeline Status indicator — Indicates the status of the input buffer in the decoder.
Adjust the Playback Delay (d) so that the meter sits at the mid point.
•
If the meter swings left, it indicates that the buffer is underflowing.

Peripherals Page and Serial Port Control
The VN-Matrix units can pass bidirectional serial (RS-232) data or control signals, such as
for serial control of a projector, across the network. See “RS-232 Over LAN Port“ and
“Serial Port Wiring“ in the “Installation section”. Serial data is sent independently of the
other streams on the network and it is not necessary to have a direct encoder to decoder
relationship.
In Pass-through Control Mode (see figure 40), serial data is passed from one VNC 325 to
another. Data flow is fully bidirectional and is independent of whether the VNC 325 is an
encoder or decoder. Thus, control of external equipment is supported.

single file, “upgrade_verx.x.tar”, where verx.x is the version number. Copy the upgrade
file onto the computer that you use to access the VNC 325 unit that is designated as the
controller.
Firmware upgrade is a multi-stage process, highlighted in table 10 and figure 42. The
detailed procedure begins on the next page. Extron recommends that all VNC 325 units in
the system be upgraded to the same firmware version to ensure full compatibility.

NOTES: � The activate and commit stages reboot the controller. This results in two
considerations:
•
The upgrade file in the temporary storage area of the controller codec is
erased. Extron recommends that you:
•
Prepare all devices first (the upgrade page displays the
READYTOACTIVATE message.
•
Then activate the upgrade on each device (the upgrade page displays
the READYTOCOMMIT message), starting with the controller VNC 325.
If you inadvertently activate the upgrade in the controller codec before all
devices are prepared, upload the file again (see below).
•
�
There is a temporary loss of the network interface. Wait 30 seconds to
allow the VNC 325 to reboot, then refresh the browser.
Perform the activate stage on the controller codec first to ensure that the new
firmware controls the upgrade of the remaining devices. Extron recommends
that you activate all devices (the upgrade page displays the READYTOCOMMIT
message) before committing to the controller upgrade.
Uploading the upgrade to the controller codec
Upload the file to a temporary storage area on the controller VNC 325 in accordance with
the procedure below. From this location, it can be installed on all codecs in the system.
1. Login to the network interface (see “Startup and Login“ in the “Installation and
Setup” section).
2. On the device list page, click anywhere on the row (except the Delete column) for the
controlling VNC 325 to select that codec to receive the firmware upload (a on figure 43).

Simple Network Management Protocol
Alarms
The VNC 325 generate alarms for range of error conditions, defined in the “Alarm types
and descriptions“ section. Alarms can be monitored at a number of locations throughout
the network interface as identified below:
•
Alarms page (see figure 49, below) — The list immediately beneath the filter settings
panel details the alarm conditions that are currently active on the system.
•
Alarm Logs page (see figure 51) — This page provides a historical log of when an
alarm condition was raised and cleared.
•
Device list page (see figure 16) — A “traffic light” symbol in the Status column
represents the status of a device.
•
In the top right hand corner of each network interface page —
The device status and system status is displayed.
In addition, the red LED located on the front panel of the codec illuminates whenever a
critical alarm is triggered.
Alarm conditions, once triggered, remain active until 5 seconds after the error that caused it
has cleared.

Filter settings panel
The Filter Settings panel (see figure 49, on the preceding page) allows you to modify the
default settings for each alarm type.
a Alarm Type — Selects an alarm for which you want to
change its default settings. This drop-down box lists the
available alarm error conditions for all units. Alarm error
conditions are divided into three categories
•
Alarm errors that occur on an encoder (see table 11)
on page 61.
•
Alarm errors that occur on a decoder (see table 12)
on page 62.
•
One alarm error that occurs only on the device that is
configured as the system controller (see table 13) on
page 62.
b Alarm Source —
Select the device for which you want to change its default settings.
Alarm filters can be set for either a single, specific unit or for all
VNC 325 devices in the system.
c Alarm Severity — Set the alarm severity. Each alarm condition has
a default severity which can be overwritten using the filter controls.
Note that the default setting is listed in this drop down independently
of any changes that have been made to the alarm severity.
Alarms can be set to one of three severities, as listed in the table below:
Alarm Severity Description
Critical
When triggered, a critical alarm:
•
Illuminates the red LED on the front panel of the affected unit.
•
Closes the normally open contacts and opens the normally
closed contacts of the relay accessed via the RS-232 Over LAN
port.
•
Displays the red traffic light indicator for the device on the
device list page.
Warning
When triggered, displays the yellow traffic light indicator for the
device on the device list page.
None
Effectively filters the alarm condition; it still appears in the alarms list
but it does not display any colored indicators.
d Alarm Reporting — Set the alarm to be either Reporting,
NotReporting, or Default (the default setting for the alarm
condition, which could be either reporting or not reporting). A
Reporting condition causes the encoder to send an SNMP trap
(an asynchronous notification) to an SNMP client whenever that alarm condition is
triggered.
The default setting is listed in this drop down independently of any changes that have
been made to the alarm reporting.
e Apply filter change button — Click the Apply filter change
button to temporarily apply the alarm changes.
NOTE: Click the Save All tab to permanently save the alarm settings.
Changes are lost after a power cycle unless you Save all.

Simple Network Management Protocol
NOTE: SNMP is an internet-standard protocol for managing devices on IP network and
a component of the Internet Engineering Task Force (IETF) Internet Protocol
Suite.
It is not the intent of this guide to define SNMP further than this and this
section is intended for users who are familiar with SNMP protocol.
The VN-Matrix 325 system can report alarm events via an SNMP trap, providing simple
integration with network management systems (NMS).
•
When communicating using SNMP, the VN-Matrix 325 system complies with the
requirements of SNMP v3.
•
When generating SNMP traps, the VN-Matrix 325 system complies with the
requirements of SNMPv1 or SNMPv2C (user-selectable using the SNMP filter settings
panel on the alarm logs page [see figure 52]).
Figure 52. SNMP Filter Settings Panel
SNMP variables that you may need to change include:
•
The SNMP password
•
The SNMP community value
•
SNMP trap destination values
SNMP Password Value
The SNMP password is the same as the administrator password. By default this is set to
admin.
You must to enter the administrator password on the accounts page before SNMP can be
used. This process must be carried out for each of the following circumstances:
•
When first using the system
•
After a firmware upgrade to the system
A password for SNMPv3 must be exactly eight characters long.
•
If the administrator password is less than eight characters in length then the remaining
characters are packed as follows: “admin“ becomes “adminadm” (exclusive of the
parentheses).
•
If the administrator password is longer than eight characters then the value is
concatenated: “concatenate“ becomes “concaten” (exclusive of the parentheses).
NOTE: These password rules apply to the SNMP management software password
only and have no affect on the network interface login.
VN-Matrix 325 Serial Digital Over IP CODEC • Alarms and SNMP
64
SNMP Community Value
The SNMP community value, defined within the protocol, acts as a password. It
authenticates messages between the VN-Matrix 325 system and the NMS. By default, the
community string is set to public. This value can be changed, using the SNMP filter settings
panel (see figure 52) on the alarm logs page. The community string must match that in use
by the NMS; if not then it may not be possible to manage the VNC 325 device.
SNMP Trap Destination Values
The Create Trap Destination field in the SNMP filter settings panel (see figure 52) on
the alarm logs page is used to add and remove destination IP addresses for NMS servers.
Multiple destinations may be added.

assembly, the operating ambient temperature of the rack environment may be greater
than room ambient. Therefore, consider installing the equipment in an environment
compatible with the maximum ambient temperature (Tma = +95 °F, +35 °C) specified by
Extron.
•
Reduced air flow — Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
•
Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
•
Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
•
Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (such as use of power strips).
