Introduction This section introduces you to the VN-Matrix 200 Series (VN 200). The topics covered in this section are: • Overview • Firmware Version • Product Range • VNC 200 DVI-I — Codec • VNE 200 DVI-I — Encoder Only • VND 200 DVI-I — Decoder Only • Functional Overview • Front Panel Features • Rear Panel Features NOTE: This document covers the VNC 200 DVI-I (Codec) matrix switcher only, although both the VNE 200 and VND 200 may be referenced. Encoder features may apply to the VNE 200.
Firmware Version This user guide is based on v3.8 firmware. You can check for newer firmware releases and user guide updates by visiting our web site at www.extron.com/downloads. TIP: To check which version of firmware is currently installed, see “Upgrading Device Firmware.” Product Range There are three VN 200 Matrix products. These units are compatible with each other, but there are some feature limitations and differences between each variant.
VND 200 DVI-I — Decoder Only The VND 200 is a decoder-only device and is compatible with other VN-Matrix products including the VNM Enterprise Controller and the VNC 200 configured as a controller. The VND 200 does not support: • Mouse and keyboard operation • RS-232 client / server operation IN RS-232 REMOTE TO PC IN POWER OVER LAN OUT/ LOOP 12V DC 5A MAX AUDIO SPDIF 1 — LAN — 2 OUT/LOOP DVI-I IN Decoder Figure 3.
Decoder Display Capability As a decoder, the VNC 200 is compatible with both digital (DVI) and analog (RGB) graphics sources up to UXGA (1600 x 1200 at 60 Hz, 24-bit color) resolution. NOTE: By default, sources are displayed at their native resolution and format. The decoded image may also be scaled by the decoder to match the native resolution of the local display. Control Capability Source control The VNC 200 provides loop-through connections for the keyboard and mouse of the source computer.
Example System Application The diagram below shows an example system application utilizing eight VNC 200 units. Four are configured as encoders (sources) and four as decoders (displays). Each device is connected to the network. Configuration of each device, including which source is displayed on which display, can be achieved by any PC or laptop on the same network using the VNC 200 integrated web management system. Figure 4.
Multicast RTP This method uses a real-time variation of UDP (User Datagram Protocol), called RTP (Realtime Transport Protocol). Multicast RTP allows a source to be displayed on any number of displays. SOURCE VN-MATRIX (encoder) DISPLAY RTP Encoder sends data using RTP to a multicast group NETWORK RTP VN-MATRIX (decoder) RTP VN-MATRIX (decoder) RTP VN-MATRIX (decoder) RTP VN-MATRIX (decoder) RTP Any number of decoders can be part of the multicast group Figure 5.
SOURCE VN-MATRIX (encoder) DISPLAY RTP NETWORK Encoder sends data using RTP to up to 4 specified decoders Figure 6. RTP VN-MATRIX (decoder) RTP VN-MATRIX (decoder) RTP VN-MATRIX (decoder) RTP VN-MATRIX (decoder) Unicast RTP The source encoder defines the display decoder(s) that the source is available to, but the decoder chooses which source to display. RTP provides very low latency which is important for video transmission. Unlike other protocols, RTP packets include a time stamp.

OUT/LOOP d f h DVI-I IN i VN-Matrix 200 Rear Panel Full details of connector types, pin-outs, and specifications can be found in the “Technical Data” section. Briefly, these are as follows: a DC power connector — The VNC 200 requires a 12 VDC regulated power supply via this connector. A suitable power supply unit (PSU) is provided.
Installation and Basic Setup Procedure This section describes the following: • Choosing a Suitable Location for Mounting • Environmental Requirements • Mounting Requirements • Power Connection via PSU • Power Cord for PSU • Setup and Connection Procedure Choosing a Suitable Location for Mounting The VNC 200 is designed to be used either as a free-standing unit or mounted in a 19-inch rack using optional mounting kits.
After the VNC 200 has been in use for a period of time the external casing may become slightly warm to the touch. Ensure that any adjacent surfaces will not be affected by the heat. Ventilation DO NOT obstruct the ventilation openings during use. The VNC 200 has an integral forced-air cooling system. A fan draws air in through the ventilation openings in the front panel and expels the heated air through the openings in the back panel.
Rack Mounting Always use the special under-desk mounting kits (optional) to secure the VNC 200. See “Optional Accessories” for the under-desk mounting kit. Full details on using the kit are included with each kit. It will be necessary to remove the four feet prior to rack mounting. Never place other units directly on top of the VNC 200 when it is rack-mounted as this will place excessive strain on the mounting brackets.
Power Cord for PSU The PSU is equipped with a 3-pin (male) type connector which requires a power cord fitted with a corresponding 3-pin IEC320 (female) connector. The type of power cord that is supplied will be appropriate for use in your country: WARNING: Do not allow anything to rest on the power cord. Power-up Procedure You must always ensure that the VNC 200 is powered on at the same time as the source computer or slightly before.
External Supply Protection CAUTION: The power cord supplied with this product is rated at 10A maximum and must be protected from overload by an external fuse or circuit breaker. Fused plugs (UK style) If the power cord is fitted with a UK style BS1363 3-pin plug (i.e. with provision for an internal fuse), then it must be fitted with a BS1362 ASTA approved 1 inch cartridge fuse. This fuse must be rated at a maximum of 10A/250V.
Network Communications Setup To establish a serial communication link… 1. Using a null modem serial cable, connect the serial port of a PC or laptop to the Remote serial port on the VNC 200 to be configured. VNC 200 IN TO PC REMOTE RS-232 IN POWER OVER LAN OUT/ LOOP 12V DC 5A MAX AUDIO SPDIF 1 — LAN — 2 OUT/LOOP DVI-I IN PSU Power Source Figure 10. Establishing a Serial Communication Link 2.
To access the setup menus… 1. Connect power to the VNC 200 or, if already connected, cycle the power off then on. 2. The VNC 200 will start sending setup/diagnostic data which should appear in the HyperTerminal window. After a few seconds, this will conclude with a display similar to this: VN Matrix(R) Maintenance Console: ver3.
Network Port Specific Options Option Function Comment 0 and 10 Network port link speed Select this option to set the network link speed. 1 and 11 Set STATIC or DHCP Entering 1 or 11 will toggle this option. When DHCP is selected, items 2 through 5 and 12 through 15 are not accessible. NOTE: 2 and 12 Set the local address of the network port It is necessary to assign a known IP address for the controller. This address must be entered manually into each VNC 200 unit.
17 IP forwarding By default, this parameter is set to 0. For normal operation, there is no need to modify this setting. Setting a value 1 will enable IP forwarding between the two network ports on the device. This function is not required for normal operation of the device. 8 Set the number of the port that is used for communications with the system controller. By default this is set to 5432, and this may be changed if required. Note that all VNC 200 units MUST have the same port number assigned.
Connect Devices Supplied cables A set of cables is supplied with the VNC 200 to accommodate a variety of standard connection requirements. The VNC 200 is compatible with both digital (DVI) and analog signals. The unit is provided with the additional cables that you may require.
Hubs are not suitable for use with the VNC 200 as they restrict bandwidth. NOTE: For normal VNC 200 operation, use Network Port 1 only.

Figure 33. Nodata Slash Mode Nodata Splash Mode If a VNC 200 decoder is not displaying a source (for example, if no source is selected, has become disconnected, or is in the wrong format), it offers two different display options. The required option is selected using the Nodata Splash checkbox: • Displays a splash screen (see example right), or • Displays the last frame of valid source data (black if no data is available).
Figure 34. Decoder Output Format Clean switching Clean switching provides a method by which streams may be decoded and displayed without disruption to the image that is displayed on the local decoder display. Clean switching is supported in the VN Matrix Enterprise Controller that manages all aspects of the system configuration.
Troubleshooting If you have followed the procedures on the preceding pages, you should by now have set up at least one VNC 200 encoder, one VNC 200 decoder, and be able to display the source (encoder) on the display (decoder). If not, this section will help to diagnose most problems that you may encounter. Display Checkup Most problems in a VNC 200 system will manifest themselves as some kind of disruption of the target display.

START Check that you are using a supported web browser. Check that the VN-Matrix controller device is powered and connected to the network. Check that you have the correct IP address for the VN-Matrix controller device and try pinging the controller from the control PC.
Serial Transport and Control Methods This section describes the following: • Overview • Setting Up a Serial Passthrough Group • Serial/Telnet Commands • Data Stream Mode Overview Routing of external serial (RS-232) communications can be achieved between any VN 200 units on the same network. Serial traffic can be: • Unidirectional as part of a source stream (encoder to decoder) • Data Stream Mode (licensed option) • Bi-directional and independent of any source stream • Passthrough Mode.
RS-232 VN-MATRIX (server) TCP NETWORK Data input to the server is sent to the outputs of all clients simultaneously. Data input to each client is sent to the server output. Simultaneous data input is processed on a "first in first out" basis. TCP VN-MATRIX (client) RS-232 TCP VN-MATRIX (client) RS-232 TCP VN-MATRIX (client) RS-232 Serial ports on each VN 200 need not share a common baud rate.
3. The Serial Port Control options are shown below. 4. Using the mode drop-down menu select the client option (note that this will reveal the destination box). 5. Using the destination drop-down menu select passthrough for the appropriate server. 6. Change the other settings as required, then click the Save All tab. Serial / Telnet Commands The following commands can be used to provide basic remote control of a VN 200 system.
Device Commands mode Changes the operating mode of the specified device. Is the device serial number of the device or the user-defined device name. Is the required mode and can be set to: • enable – for normal operation • disable – to stop encoder source streaming or stop display output on a decoder • standby – to stop encoder source streaming or display splash screen on a decoder Example: mode 16 enable channel
Data Stream Mode NOTE: Data stream mode is not supplied as a standard feature on VNC 200 Codec devices. In this mode, data received by an encoder is transported to the decoder, along with video and audio, as part of the source stream. Data transport in this mode is unidirectional and is capable of being recorded (and played back) by the VNM Recorder.
6. Return to the Device List page and do the same for the decoder device. NOTES: • No data will be transported until the decoder connects to the encoder stream. • The Peripherals tab is NOT present in the VN 200 device type.This is for bullets after a first bullet level.
Remote Keyboard and Mouse Operation This section describes the remote keyboard and mouse operation. Overview When a PC source is being viewed by a VN 200 decoder, remote keyboard and mouse control of the source PC can be achieved via the decoder unit. For remote keyboard and mouse functionality to be possible: • The keyboard and mouse ports of the source PC must be fully connected to the VN 200 encoder (see “Connect Devices”).
To Terminate a Remote Control Session Using Hot Keys Using the keyboard attached to the VN 200 decoder or encoder, press the key twice, followed by the key. Both the source monitor and display monitor will briefly show MK:Local in the top left-hand corner as shown here. MK:Local MK:Local Mouse and Keyboard Control 1. Login to the web interface (see “System Configuration”). 2. From the Device List page click on the required encoder device. 3.
Configuring mouse and keyboard control The Mouse and Keyboard control may be configured using the options provided in the Peripherals tab. This configuring can be used to modify the way in which the hot keys (covered on the preceding pages) operate, as described in the following tables. Source (Encoder, VNC 200 DVI-I and VNC 200 DVI-I A Only) Item Control Option Description MK mode Enable Allows remote mouse and keyboard connection from a decoder. This is the default state of this control.
Display (Decoder, VNC 200 DVI-I and VNC 200 DVI-I A or VND 200 DVI-I) Item Control Option Description MK mode Disable Blocks remote mouse and keyboard to an encoder. Effectively disables hot key feature. Keyboard Normal mouse and keyboard operation Permits the hot key feature. This is the default state of this control. Keyboard & Keep alive The mouse and keyboard connection will be reestablished if it fails, providing that the target encoder is configured with Mode = Enable.
Advanced Setup Procedures Encoder Set Up This section provides details for advanced set up options for a VNC 200 encoder.
Video Setup Page All advanced source setup is achieved via the Video Setup page. To access the Video Setup page, follow the numbered steps in the diagram below. Click on the Video Setup tab on the Configure (videoPort) page for the relevant VNC 200 encoder.` 1 2 3 Figure 40. Video Setup For most source types it is recommended that you select auto from the mode drop-down menu, allowing full auto-detection of the source.
Fine-tuning a Source (Manual Overrides) The following adjustments are classed as manual overrides. These adjustments are not saved as part of the current source mode and, once applied, will remain in force until they are changed. e b a d c Figure 41. Manual Overrides a Phase (Pixel Clock) — When an analog graphics signal is being digitized, it is essential that each pixel be sampled as close as possible to its center in order to obtain a stable value.
c Blanking (Image Positioning) — In analog video and graphics sources, active video occupies an area in the middle of the video frame. Around this is a non-active area used for horizontal and vertical blanking signals. The VNC 200 normally ignores the blanking area and only digitizes the active video area. To do this, it needs to know the position of the first active line of video and the first active pixel on that line. This is controlled by the blanking parameter.
1 2 3 Figure 42. Setting the EDID Mode To set the EDID mode, perform the following steps: 1. From the web interface, select the VN-Matrix defined as an encoder (source) device. 2. Click the videoPort0 icon. 3. Click the Configure tab. 4. Select the appropriate EDID mode. In most cases, Transparent will be the correct option. This will allow the EDID data of the display to pass through the matrix to the source PC. 5. Reboot the source PC to ensure it reads the proper EDID selection.
TIP: The EDID of your monitor has a huge effect on what mode your graphics card displays. Also, the mode selected on the source PC may not produce the expected output resolution. For example, if the EDID of a monitor does not report any widescreen modes, your graphics card may still allow resolutions such as 1280x960, 1280x768, or 1280x720. In this instance, the PC may output 1280x1024, and letterbox the widescreen image so it is vertically centered on the monitor.
NOTE: A stable video signal on the loop output of the VN-Matrix encoder does not necessarily indicate that the signal is being properly recognized since a VN-Matrix encoder generates the loop output signal by passing sync directly from the input connector to the output connectors (a passthrough), so it is not dependent on any previously stored modes to create a loop output.
1 2 3 Figure 44. Custom Input Mode 1. From the web interface, select the VN-Matrix device defined as an encoder (source) a. 2. Click on the VideoPort icon b. 3. Select the Video Setup tab c. 4. Set phase to Auto.
5. Set the macrovision defeat mode to the appropriate setting. If the source has Macrovision encoding, select the check box; otherwise, leave it deselected. 6. Set color space to RGB or YPrPb, based on the input signal type. NOTE: The above values are not saved as part of the source format; they are global setting saved for the mode selected in the mode drop-down list. If auto is selected in the mode drop down list, the settings will apply to any detected mode. 7. Set blanking to auto. 8.
20. Click the Save Source button; this will save the User.Source.Config file of the VNMatrix device designated as the controller. 21. With the mode drop down list still set to auto, the VN-Matrix device should now select the new user mode in the currentMode field. 22. Put up a moiré pattern and check for any clocking errors. If clocking errors exists, select the User mode from the Name drop-down menu and adjust the value in the PixelsPerLine field.

Bandwidth Management This page can be set to show two levels of detail, by selecting the More Detail or Less Detail button. The above view provides simple control of the Encoder compression settings. Select More Detail to reveal the view as shown below. Using the lower control panel (Video Quality), provides for more complex control of the encoder compression settings.
Bandwidth Management – Simple Control Setting the maximum bit rate The maximum bit rate of the streamed image may be set using the Bandwidth slider. The Bandwidth slider may be adjusted from unlimited to 1 Mbps. The selected maximum bit rate is displayed on the right hand side of the slider bar. When the slider is set to unlimited, no bit rate limit is applied and the actual bit rate will depend on the complexity (detail and motion) of the source image.
A low setting will provide the lowest image quality (with the highest compression). The bit rate of the streamed image will be affected as the Video Quality slider setting is adjusted. Note that a low setting may result in a blocky looking picture. Transform setting The compression system supports two Transform types: • Graphics is optimized for text and sharp lines, such as is present on most computer screens.
Temporal compression setting Temporal compression may be applied by selecting the Temporal check box. By default, this option should always be selected. Temporal compression causes data to be transferred only when a change occurs between frames. Quality Control settings The Threshold setting modifies the detection point of the temporal compression algorithm. A value of 0 results in all changes between frames being sent.
Monitoring the bit rate The bit rate of the streamed image may be monitored at the Streams information area of the Bandwidth Management page. The Streams list shows network statistics for current RTP streams. For each RTP stream, three values are presented: the Transmit Bandwidth (in Megabits-per-second), the packet Drop Percentage and the Round Trip delay Time (RTT — in microseconds). The Tramsmit Bandwidth is the true bandwidth of the source measured over the last second.
• CBR-F – The compression settings are dynamically modified to maintain the transmit bandwidth at the specified rate. Additional refresh is added to maintain the bandwidth as required. Filter averages bit rate over a period of one second. • PBR-F – The compression settings are dynamically modified to limit the transmit bandwidth to the specified rate or below. The specified compression setting is used as the minimum compression value. Filter averages bit rate over a period of one second.
Decoder Set Up This section provides details for advanced set up options for a VNC 200 decoder. • Setting optimum playback delay — See “Setting Optimum Playback Delay” • Monitoring bandwidth usage — See “Bandwidth Monitoring Page” • Creation of custom output modes — See “Creating a Custom Output Mode” Setting Optimum Playback Delay During playback of a source stream, data is transported from a VNC 200 encoder across the network and into a buffer on the VNC 200 decoder.
1 2 3 Figure 46.
Adjusting the Playback Delay a b c Open the video Bandwidth page for the video object. Enter a value into the Playback Delay field and click the Update button. Check the Pipeline Status indicator to ensure that the Playback Delay is at a valid level: Setting is valid and should give a stable image. Playback delay is too small. This will result in the playback image jumping as network loading changes. Playback delay is too large.
Custom Output Modes The Output Format Management screen allows the user to create custom video formats for displaying decoded video data streams. 1 2 3 Figure 47.
Creating a CVT output mode This procedure will require the user to access the VN-Matrix decoder unit over a Telnet connection and access the VN-Matrix web GUI using a browser window. 1. Ensure that the graphics source that is causing issues is connected to the VN-Matrix encoder, and that the encoder has detected the correct mode for that source. NOTE: Make sure that the source is displaying an image that occupies the entire desktop, such as a window that has been maximized. 2.
2. Select the Device tab. 3. Click on the display0 link in the Configuration region. 4. Use the Output Format drop-down list to select the mode you created in the previous section. 5. Select Update. The source should now be displayed correctly on the decoder output. The mode must now be modified so that it can be detected automatically when the source is connected to the encoder. To do this, you will: 1. Retrieve timing information using a telnet session. 2.
Entering the timing values in the VN-Matrix web GUI 1. Return to the VN-Matrix GUI and navigate to the Format tab of the decoder. In the Name drop-down dialog ensure that the mode that you have just built is selected and click Update. Figure 48. User Output Format 2. Calculate the correct horizontal values for the mode that we are using. We will assume that the Horizontal Left Border, Horizontal Right Border, Horizontal Front Porch, and Horizontal Sync Width are already correct. 3.
9. Enter your value in the Vertical Back Porch field. 10. The final element is to calculate the Pixel Clock Frequency.

Alarms and SNMP This section describes the following: • Overview – Alarms • Overview – SNMP • SNMP Trap Destinations Overview – Alarms The VN-Matrix system is configured to generate alarms for error conditions. A list of these error conditions and their meanings are presented on the following pages. Alarms can be monitored at a number of locations throughout the web GUI • In the Alarms page • • In the Alarm Logs page • • In the list immediately below the Filter Settings box.
Alarms Page The Alarms screen enables a user to define and monitor system alarms. Figure 52. Alarms Page Filter Settings The Filter settings section allows the default settings for each alarm type to be modified. • Alarm Type — Select the particular alarm that is to have its default setting changed. • Alarm Source — Select the device on which the alarm is to change. • Alarm Severity — Set the alarm severity.
Alarm Type This drop-down menu lists the available alarm error conditions for all units. Alarm error conditions are divided into two categories: • Alarm errors that occur on an encoder • Alarm errors that occur on a decoder In addition, there is one alarm error that only occurs on the device that is configured as the system controller. Alarm Source Alarm filters may be set for either a single, specific unit or for all VN 200 devices in the system.
Alarm Logs A historical list of the last 200 alarm events is provided in the Alarm Logs 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. The log holds a historical record of the last 200 alarm events. When more than 200 events occur, the oldest event is deleted from the log. Alarm events that are listed in the log may be sorted by Type, Raise Time and Severity.
Encoder Alarm Alarm Type Description - Encoder Alarm Type Description Action Default Settings No source No source present at the input. Check input connections; is there an output on the loop through connector? Critical, reporting Bad source syncs Source is present, but unrecognized ue to bad sync measurement. Critical, reporting No SDI source lock Applicable to VN 300, ignore for VN 200. Critical, reporting Unsupported SDI mode Applicable to VN 300, ignore for VN 200.
Decoder Alarm Alarm Type Description - Decoder Alarm Type Description Action Default settings No decoder video data 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.
Overview – SNMP The VN 200 device has the ability to report alarm events via an SNMP trap, providing simple integration with network management systems (NMS). When communicating using SNMP, the VN 200 complies with the requirements of SNMPv3. When generating SNMP traps, the VN 200 complies with the requirements of SNMPv1 and SNMPv2c. Using SNMP - Password The SNMP password is the same as the administrator password. By default this is set to admin.
SNMP Trap Destinations The Filter Settings dialogue in the Alarm Logs page is used to add and remove destination IP addresses for NMS servers. The IP address of the NMS should be entered in the Create Trap Destination box. Multiple destinations may be added.
IP Addressing What is an IP Address? A full explanation of IP addressing is beyond the scope of this user guide. However, the following details will provide you with enough information to get started. An IP address is a 32-bit binary number that is used to identify each device on an Ethernet network. This number is usually represented by four decimal numbers (each in the range 0 to 255) separated by dots, for example, 198.123.34.240. This is called “dotted decimal notation”.
Multicast Address Range A further range of addresses is available for multicast usage: 224.0.0.0 – 239.255.255.255 These addresses (also known as Class D addresses) are used to allow several devices to be part of the same multicast group. Each device in the group has the same multicast address and can effectively send data to all other devices in the same group simultaneously.
Subnet Mask The subnet mask is another 32-bit binary number that is used to “mask” certain bits of the IP address. This provides a method of extending the number of network options for a given IP address. It works by allowing part of the host identifier to be used as a “subnet identifier”. It is important that you set the correct value for the subnet mask. The basic values depend on the class of IP address being used: Class Name Subnet Mask Class A 255.0.0.0 Class B 255.255.0.0 Class C 255.255.255.
If you get the message... Reply from 208.132.180.48: Destination host unreachable. …this indicates that the IP address of the computer is not in the same class (or subnet) as that of the device being “pinged”. Check that the subNet mask on both the computer and the device are set to the same value (see “Subnet Mask”). Also check that both IP addresses are within the correct range for the chosen class and are compatible (see “Choosing IP Addresses”).
Understanding Network Performance This section describes features of the network. Network Characteristics There are a number of characteristics of networks that have to be taken into account when transmitting image data. When a conventional analog or digital video signal is sent from a source to a display, the image is transmitted in real time with negligible delay (or “latency”).
The introduction of gigabit (1 Gb/s) Ethernet has allowed the introduction of “Jumbo” frames with more than 1500 data bytes. Clearly the overhead involved by limiting the number of bytes to 1500 is considerable, and using jumbo frames makes more efficient use of the network. However, the following should be noted: • Many real world networks only operate at 100Mb/s at local level and these cannot accept jumbo frames. • Many gigabit networks are not configured to accept jumbo frames.
The OSI model is used as a reference, and while some systems follow the full model, others simplify it by combining the functions of certain layers. In particular the protocol stack (which is the basis of standard Ethernet communication) only has four layers, as indicated in the figure below. The Internetwork layer combines the functions of the Data Link and Network layers of the OSI model and looks after addressing, carrying Internetwork Protocol (IP) within the MAC frame.
Clearly the most significant difference is that UDP is “best effort” and TCP is “guaranteed delivery”. TCP is used in most networks for tasks such as exchanging file information between nodes, because absolute accuracy is required and because the delivery requirement is usually “point to point”. The table implies several different methods of transmission, for example: • Broadcast where a message goes to all nodes on the network. Must be UDP. • Unicast where a message goes from one node to another.
