Introduction • About this Guide • About the VNC 325 Codec • Features 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.
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.
Features Supports broadcast quality video formats (see table 1) Table 1. Supported Video Formats Video Format SMPTE 424 / 425M SMPTE 292M SMPTE 259M Resolutions 1080p @ 50/59.94/60 Hz 1080i @ 50/59.95/60 Hz 1080p@23.97/24/25/29.97/30 Hz 720p @ 23.97/24/25/29.97/30/50/59.94/60 Hz 525i @ 59.94 Hz 625i @ 50 Hz Color space 10-bit, 4:2:2, YCrCb 10-bit, 4:2:2, YCrCb 10-bit, 4:2:2, YCrCb Autodetection — The codecs auto-detect the format of the connected signal.
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.
Installation and Setup This section details the installation and initial configuration of the VN-Matrix VNC 325 codecs, including: • Installation and Setup Overview • Rear Panel Features • Mounting the Units • Planning the System Architecture • Configuring Network Settings • Making Remaining Connection • Configuring Encoders and Decoders Installation and Setup Overview This section introduces a checklist of the actions that you should do in the order shown to install and configure all of the V
Rear Panel Features NOTE: This “Rear Panel Features” section identifies the various ports on the back of the VNC 325 and defines their function. Do NOT make any network (LAN) connections until directed in the connection and setup procedures that begin after this section. 1 2 REMOTE POWER RS-232 OVER LAN OPTICAL 12V DC 3A MAX 1 3 4 LAN 2 5 SDI IN SDI OUT 6 7 8 Figure 2. VNC 325 Features NOTE: a The VNC 325 uses male connectors for the serial ports (a and b). You may need an adapter.
d LAN port 1 (RJ-45 port) — Use either this port or the fiber optic network port (e) to stream video and audio data across a network, to control the VN-Matrix system, or both. e LAN port 2 (fiber optic port) — Use either this port or the RJ-45 network port (d) to stream video and audio data across a network, to control the VN-Matrix system, or both. NOTES: • Do NOT connect VN-Matrix units to an existing network until each is correctly configured.
Data Transport Methods 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).
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 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.
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.
Table 2 shows the codec configuration settings for example 1. See “Configure Network Settings” on page 16 to make these settings. NOTE: Table 2. A gateway value must be set on the streaming port otherwise no streaming status is available in the HTML network interface. Applicable Codec Configuration Selections Codec 1 Option LAN Port 1 (RJ-45) Option LAN Port 2 (fiber optic) 2 Address: 172.28.0.1 12 Address: 192.168.0.1 3 Netmask: 255.255.0.0 13 Netmask: 255.255.255.0 4 Gateway: 172.28.0.
Example 2: 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 7. Figure 7 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 2.
Table 3 shows the codec configuration settings for example 2. See “Configure Network Settings” on page 16 to make these settings. NOTE: Table 3. A gateway value must be set on the streaming port otherwise no streaming status is available in the HTML network interface.

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.

Applicable Codec Configuration Selections Codec 1 Option LAN Port 1 (RJ-45) Option LAN Port 2 (fiber optic) 2 Address: 172.28.0.1 12 Address: 192.168.1.1 3 Netmask: 255.255.0.0 13 Netmask: 255.255.255.0 14 Gateway: 192.168.0.250 17 Controller ip: 192.168.1.1 Codec 2 Option LAN Port 1 (RJ-45) Option LAN Port 2 (fiber optic) 2 Address: 172.29.1.
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.
6. Type the default password config and press . 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. • This procedure identifies the selections that you may need to make for typical low level configuration only.
Configuration Selections NOTES: • In a typical installation, you: • Must change the address (2 or 12), netmask (3 or 13), gateway address (4 or 14), and controller IP (7). • May need to change the boot method (1 or 11). • Most installers do not need to change the other selections. If you do change settings, note the existing values before the change in case you need to change back. • Options 0 through 6 are the settings for LAN port 1 (the RJ-45 port).
LAN Port Specific Options Option Function Comments 4 and 14 gateway: Set the IP address of the default gateway. • Gateway values must be set on the streaming port otherwise no streaming status is available in the HTML network interface. The default gateway must be on the same subnet as the port to which it is assigned. Manually enter the gateway address for the port; use no leading zeroes. For example: 192.168.0.1 is valid, 192.168.000.001 is not valid. NOTE: Only one default gateway is supported.
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.
e LAN 2 port (Optical) — If desired, connect an IP fiber cable terminated with an LC connector. OPTICAL NOTES: • Extron does not supply the plug-in SFP module for the Optical network port. 2 • 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.
Video Input, Output, and Loop Connections The three video connections are connected differently, depending on whether the codec is to be configured as an encoder or a decoder. Encoder configuration See figure 13. a SDI Out BNC connector — This connector provides a buffered loop through of the original source with or without an optional text overlay.
Decoder configuration See figure 14. a SDI Out BNC connector — Connect an SDI, HD-SDI, or 3G-SDI digital video device to display the digital video that was streamed to the decoder (item B on figure 14). The video output is in the same format as the originating source at the encoder. When no video streams are being decoded, this output can provide either a frozen image of the last received frame or a static splash screen.
Configure Encoders and Decoders NOTE: Perform the procedures in this section after you connect all codecs in the system to a network. After the low-level configuration described on page 17, system configuration and operation is via the network interface (built-in HTML pages) of the unit designated as the controller. The pages can be viewed by any web browser, such as Mozilla Firefox, version 4.0 or newer (preferred), or Microsoft Internet Explorer, version 6.
4. Enter the Username and Password. NOTES: • The VN-Matrix 325 codecs have two valid usernames: • admin — allows full read/write access to all setup parameters. • public — allows read-only access to setup parameters. • As shipped from the factory, the password for both usernames is the same as the name itself (the password is “admin” for the admin username and “public” for the public username). • The password can include letters, numbers, and the underscore character. The password is case-sensitive.
Configure the Units as Encoders or Decoders A typical VN-Matrix 325 network (see figure 17) includes an encoder (source), a decoder (display), and a controlling PC. The data transport method, TCP or RTP, is defined on the decoder configuration page. Multicasting is selected on the encoder configuration page (see “Enable multicast streaming“ to select the multicast and “Data Transport Methods“ for definitions of the methods).
Configure the devices as encoders or decoders as follows. 1. On the device list page, click anywhere on the row (except the Delete column) for the device to be configured (item a in figure 18). This selects that device and displays the device page (see figure 19). 2 — or — 1 — or — NOTE: The icons displayed in this panel are available only after you create a source or display in step 3. Figure 19. Configuring a Codec as a Source or Display 2.
4. Click the display icon that appears in the configuration box after you have created a display in step 3 (a in figure 20). The display configuration page appears. 1 2 Figure 20. Source Configuration 5. Click the Video Source drop-down box and then select the video source (b). • Choose rtp(m) for multicast RTP streaming. NOTE: rtp(m) is available only if you have enabled multicast streaming. See “Enable multicast streaming“. • Choose rtp for unicast RTP streaming.
Enable multicast streaming NOTES: • The VN-Matrix 325 supports IGMP V2 for multicast streaming. • The multicast streaming setting does NOT track across all four encoder configuration pages (video, anc [ancillary, specifically audio], colfec [column foward error correction], and rowfec [row forward error correction]). For most applications, the same transport should be set for all stream elements, but this is not mandatory. 1. If necessary, click the Device tab to display the device page (see figure 19). 2.

See “Test Pattern“ in the “Reference Information” section for the test patterns. c Reset button (to the left of the LAN 2 LED) — Insert a straightened paper clip into the hole on the front panel and press and release to reboot the operating system.
Device List Page Device Field This field identifies the video format of the devices that are present on the network: • 3G — A device that operates at all resolutions up to and including the 3G-SDI standard. • HDSDI — A device that is operates at all resolutions up to and including the HD‑SDI standard. • SDI — A device that operates at resolutions up to the SDI standard. NOTE: All VNC 325 codecs are 3G.
Device Page The device page for a specific codec (see figure 25) is available when you select that unit by clicking anywhere on the row (except the Delete column) of a device on the device list page (a). Figure 25 shows the device page for a unit that is configured as an encoder. 1 6 2 3 4 5 Figure 25.
Device summary panel This panel consists of the following fields: • Name — This field displays the name of the device. You can change the name of the unit to a more meaningful value for your installation as follows: 1. Highlight the existing device name. 2. Type the new name. | 3. Click the update button. NOTE: Spaces within names can cause issues when controlling the system using a third-party control system. Extron recommends avoiding spaces within names..
Device setup panel The Device setup panel allows a codec to be configured as either an encoder or a decoder. (see “Configure Encoders or Decoders“). The panel consists of the followings: • Device Type — Select create source, create display, or (if the device is already configured) change device type. • Mode: • Enable — Normal operation; image transport is enabled. • Disable — Image transport is disabled.
Configuration Page — Video Encoder The video encoder configuration page (see figure 26) is accessed by clicking the video icon in the configuration panel of the device page and consists of two panels. This page also provides access to the bandwidth management page via the Bandwidth tab (see “Bandwidth Management Page and Typical Bit Rates“). 1 2 Figure 26.
Configuration Page — Audio Encoder The audio encoder configuration page (see figure 27) is accessed by clicking the audio icon in the configuration panel of the device page. 1 2 2a 2b 2c 3 4 Figure 27. Audio Encoder Configuration Page The page consists of four panels: • Name (a) • Audio (b) • Forward Error Correction (c) • Streams (d) Name panel The Name panel (a on figure 27) displays the name that is applied to the audio port, that is, the name of the audio and other audio data stream.
ANC (Audio) panel 2a The anc (audio) panel provides control and configuration of the audio data channels. 2b 2c The SDI/HDSDI/3G SDI video transport supports up to 16 audio channels, arranged in four groups of four channels each. • Transport Mode (Ç) 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.
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.

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.
Figure 30. FEC 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. Bandwidth Management Page and Typical Bit Rates To access the bandwidth management page (see figure 31), click the Bandwidth tab on the video encoder configure page. 1 2 Figure 31.

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.
Advanced Controls panel Click the Advanced button in the Bandwidth Management panel to access this panel. The controls in this area provide the complete set of VNC 325 image quality and bit rate tools (see figure 33). Some of the controls in the Bandwidth Management panel are duplicated here; when controls are duplicated, settings in one panel automatically track to the other panel. 1a 1b 1c 1d 1e 1f Figure 33.
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.
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 video, audio, and error correction data. The streams information area (figure 32, item Ä) of the bandwidth management standard controls panel shows the total transport bit rate as adjustments are made to compression and FEC. Table 7.
Decoder Display and Configuration Page To access the decoder display and configuration page (see figure 35), click the display icon on the device page. 1 2 Figure 35. Decoder Display and Configuration Page The available controls consist of two main panels: a Decoder video configuration controls — Provides controls for the display name and the splash screen display and displays the active format (see “Decoder Video Configuration Panel“, below).
Decoder Streams Configuration Panel 1a 1b 1d 1c Figure 37. Decoder Streams Configuration Panel For each change made in the decoder streams configuration panel, click the Update button in the video configuration panel to confirm the change. Ä Source stream selection — You can view the available active source (streams) by opening the Source drop down box. • Choose rtp(m) for multicast RTP streaming. NOTE: rtp(m) is available only if you have enabled multicast streaming.

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.
Configuring a Serial Pass-through Group NOTE: The client and server ends of the serial pass-through connection do not have to have the same baud rate settings, however having the different ends at vastly different rates can result in unexpected results. 1. Decide which device is to be the server. 2. On the device list page (see figure 23 on page 32), click on the device you want to configure. 3. On the device page (see figure 25 on page 34), click the peripherals tab. 4.
Firmware Upgrade Page Extron may occasionally issue firmware upgrades for the VNC 325. See the Extron website, www.extron.com, for details of the latest firmware release. Upgrades are supplied in a 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.
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.
4. Click the Browse button (a). The File Upload window (see figure 44) opens. 1 2 2 3 Figure 44. Upload a Firmware File to the Controller Codec 5. Navigate to the folder where you saved the firmware upgrade file, select the file, and click the Open button (b). The File Upload window closes. 6. On the upgrade page, click the upload button (c). The selected file is uploaded to a temporary memory area in the controller. This can take a few moments.
NOTE: The remainder of the installation procedure is performed using the forward button to advance the installation through the various stages. If necessary, the reverse button can back up a stage. The Device Upgrade Status field indicates the current stage or the status. The process lets you temporarily install and test the new firmware and, if it behaves satisfactorily, permanently install (commit) the new firmware. Up until the last stage, you can return to the existing firmware version.
Accounts Page (Passwords and Clock Management) To access the accounts page (see figure 46), click the Accounts tab on the device list page. The accounts page consists of the passwords panel, the clock management panel, and the controller licensing panel. Figure 46. Accounts Page Passwords Panel The VN-Matrix 325 system has three user accounts, all shown and changeable on the passwords panel (see figure 47): • Administrator — Allows full read/write access to all setup parameters.
Clock Management Panel The unit that is designated as the controller generates the system clock. All units in the system receive their time stamps from the system controller. The clock for all VNC 325 units can be changed to reflect the local time as follows: 1. Entering the local time in the New Time field in the format yyyy-mm-dd hh:mm:ss (see a figure 48). 1 2 Figure 48. Clock Management Panel 2. Click the Change Time button (b).
Alarms and SNMP This section provides a detailed examination of VNC 325 alarm conditions and its handling of Simple Network Management Protocol (SNMP). This section includes the following: • Alarms • Simple Network Management Protocol Alarms The VNC 325 generate alarms for range of error conditions, defined in the “Alarm types and descriptions“ section.
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.
Alarm list panel The alarm list panel (see figure 50) provides information on all alarm events that are currently active. Figure 50. Alarm List Panel Alarm events that are listed can be sorted by Type, Raise Time, and Severity. Position the mouse over the desired sorting heading and left-click to change the list order. The list is refreshed each time that you click the Alarms tab or change the sorting criteria. Alarm types and descriptions Encoder Alarm Table 11.
Decoder Alarm Table 12. Decoder Alarm Type and Description Alarm Type Description No decoder video data Action Default Settings Indicates that there is a valid connection, no video data present. Usually accompanied by no source data stream message in the web interface. Warning, reporting No decoder mode No matching decoder mode for the incoming stream. Warning, reporting No source report Unable to detect the format of the received data stream.
Alarm Logs page The alarm logs page (see figure 51) provides a historical list of the last 200 alarm events. Figure 51. Alarm Log Page The log provides data on when an alarm error condition was raised and cleared. Each event is paired in the log so a raise and clear event is listed together. When more that 200 events occur, the oldest event is deleted from the log. Alarm events that are listed can be sorted by Type, Raise Time, and Severity.
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).
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.
