Introduction This section provides an overview of the user guide and describes the Extron VN-Matrix (VNM) 250 series. Topics that are covered include: zz About this Guide zz About the VNM 250 zz VNM 250 System Controller zz Transport Protocols Used for Streaming zz Definitions zz Features About this Guide The VN-Matrix 250 (VNM 250) series consists of the VNE 250 encoder and the VND 250 decoder.
The VNM 250 series also supports a reverse audio channel for collaborative applications where 2-way communication is required. The VND 250 video output is available only in digital format. It can be configured to display at the same resolution and refresh rate as the encoder input or it can be scaled to match the requirements of the display attached to the decoder. The decoder supports both digital audio, analog audio, or both. The audio output is independent of the encoder audio source.
VNM 250 System Controller All Matrix systems require one device that acts as the system controller. For small systems (ten devices or fewer), this can be either a VNE 250 or VND 250. For larger systems, a VN‑Matrix Enterprise Controller must be used. Systems Controlled by VNM Enterprise Controller Systems Controlled by VNM 250 Device The VNM Enterprise Controller is able to control all VN-Matrix systems (large and small) but is required for large systems (more than 10 devices).
Multicast RTP — An Overview Multicast RTP allows a source to be displayed on multiple displays. This method uses a real-time variation of UDP (User Datagram Protocol) called RTP (Real-time Transport Protocol). RTP (m) ADJUST CONTROL MENU STREAM CONFIG STATUS ALARM Network RTP (m) ADJUST CONTROL MENU STREAM NEXT CONFIG VNE 250 STATUS ALARM NEXT VND 250 VN-MATRIX RGB / HDMI OVER IP VN-MATRIX RGB / HDMI OVER IP Encoder sends data using RTP to a multicast group.
Unicast RTP — An Overview Similar to multicast RTP, this method uses a real-time variation of UDP protocol, called unicast RTP. This method can be used where the network infrastructure does not support multicast traffic. Typically, this protocol is used for point-to-point configuration (single source to single display), but can be configured to use up to a maximum of four displays. NOTE: The encoder sends an individual stream to each decoder.
Definitions PURE3 — is specifically designed for network transmission of real time media (such as video or graphics, audio, data, and whiteboard elements). It features both spatial and temporal image compression, which allows for efficient bandwidth usage. zz PURE3 streams always contain video or graphic elements. zz PURE3 streams may also contain audio and data content that is associated with the video and graphic elements.
Synchronization of multiple streams of audio, video, or both — audio and video timing is maintained from a source across encoders preserving lip sync quality and supporting multi-source streaming applications. Decoder genlock connection for synchronized decoding — supports synchronized decoding of source streams across multiple VND 250 decoders.
USB connectors for configuration — a USB mini-B port on the front panel can be connected to a local PC for low level configuration. USB Keyboard and Mouse streaming — rear panel USB connections are provided to allow for KVM type collaboration between an encoder and decoder pair. The encoder USB ports allow connection to a local PC, while the decoder USB ports allow connection of a mouse and keyboard to remotely control a PC connected to the encoder.
Installation Overview This section provides an overview of the installation process. To set up the VNE 250 and VND 250, follow these instructions and the instructions referenced by the links provided: 1. If required, install small form-factor pluggable (SFP) connectors in the LAN 2 ports (see Streaming Network on page 16). 2. Select a suitable location and mount the VNM 250 devices (see Mounting on page 129). Depending on your system, there may be multiple locations and multiple units at each location. 3.
8. Connect the audio sources to the encoders and the audio outputs to the decoders. If required, connect the reverse audio input to the decoder and the reverse audio output to the encoder (see Audio Connections on page 21). NOTE: The reverse audio feature allows users at the decoder site to communicate with users at the encoder site. 9. If required, connect USB cables to allow KVM Function.

Connect the captive screw connector from the power supply to the power receptacle. CAUTION: Electric shock hazard — The two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring. POWER 12V 2.
The control port (LAN 1) is not required for normal operation. When necessary, this port may be used to enable control by a third-party control system. The streaming port is the primary network connection. All media and device communication is delivered over this network link. To connect to the streaming network, use either the rear panel LAN 2 RJ-45 connector or SFP (fiber optic) connector.
Streaming network (LAN 2) NOTE: The RJ-45 and SFP streaming network connectors share the same IP address. Only one connector can be active at any time. If the SFP cage is unpopulated, the RJ‑45 connector is active. If the SFP cage is populated, it becomes active and the RJ-45 connector is inactive. By default, the RJ-45 port is the active streaming network connection and the SFP cage (see figure 6, D on page 13 for the encoder or figure 7, D on page 13 for the decoder) is unpopulated.
USB Ports KVM function 1. Connect a mouse and keyboard to the VND 250 rear panel USB ports (see figure 7, F on page 13). 1 2 2. Connect a PC to the VNE 250 rear panel USB port (see figure 6, E on page 13). This connection passes the mouse and keyboard control signals to the source PC.
Coms RS-232 pass-through The Coms port on the rear panel of the encoder (see figure 6, R on page 13), or decoder (see figure 7, R on page 13) is used for RS-232 pass-through communications, allowing a control device connected to one VNM 250 unit to control a remote device connected to a second VNM 250 unit. Serial data received by one VNM 250 unit is transmitted over the network, using TCP/IP, and then converted back to serial data at the target VNM 250 unit. Data flow is fully bidirectional.
RS-232 control Tx Rx G Tx Rx COMS RS-232 control — allows low level configuration of the encoder or decoder. Use the three poles to the right of the shared captive screw connector (see figure 6, R, or figure 7, R on page 13).

System Configuration with the Enterprise Controller All Matrix systems require one device that acts as the system controller. For a small system (ten devices or fewer), this can be either a VNE 250 or VND 250. For larger systems a VN‑Matrix Enterprise Controller must be used. A system controlled by the Enterprise Controller can incorporate any VN-Matrix devices, including recorders, into the system. Systems controlled by a VNM 250 device cannot exceed 10 devices in total.
The Enterprise Controller GUI opens. Figure 10. VN-Matrix Enterprise Controller Device List 4. To configure the system with the Enterprise Controller, see the VN-Matrix Enterprise Controller User Guide, which is available at www.extron.com.
Low Level Device Configuration The RS-232 control port is used to configure the network settings for the VNE 250 and the VND 250. Follow these instructions: 1. Use an RS-232 cable to connect a control PC to the rear panel Coms port of the VNM 250 device (see page 19). 2.
4. At the Please select an option: prompt, type the number of the parameter you wish to change followed by : zz 0a or 10b — these options set the network link speed. When you choose either option, you are offered a further choice: 1. auto_10_100_1000 — configures for auto speed negotiation up to 1 Gbps. 2. auto_10_100 — configures for auto speed negotiation up to 100 Mbps. Enter 1 or 2 followed by at the prompt. The default setting is 1. auto_10_100_1000.
zz 8 — this option sets the IP address of the system controller. The controller IP address must be set to the IP Address of the streaming port on the unit designated as controller. This is the network port over which system control data is sent. The default value is 192.168.254.254. zz 18 — this option sets the number of the port that is used for communications with the system controller. The default value is 5432 but it may be changed, if required.
Setting a VNM 250 Device as the System Controller All Matrix systems require one device that acts as the system controller. For small systems (ten devices or fewer), this can be either a VNE 250 or VND 250. For larger systems, a VN‑Matrix Enterprise Controller must be used. The VNM 250 device that is chosen as the system controller must use static IP address settings. Extron recommends using Low Level Device Configuration (see page 24) to set one device as the system controller.
Configuring a VNM 250 Series Unit for DHCP VNM 250 devices may have their streaming port network settings configured using IP addresses from a DHCP server. For small systems, the VNM 250 device that is used as the system controller may also be configured to act as a DHCP server. It is then used to set the streaming port parameters of the other VNM 250 devices in the same system. For larger systems a Windows DHCP server may be used.

Select option 6 and enter dhcp. This enables the DHCP server in the device. 9. Once option 6 is set to dhcp, option 7 becomes visible. Select option 7 and enter the range of addresses that the DHCP server will use when allocating addresses. This range must include the address set for option 12 on the previous page. 6.
5. Select option 9 (Exit) to enter the Controller menu. 6. DHCPD/SLAAC server enable: none 9. Exit Please select an option: Figure 17. Low Level Configuration Menu, Page 2 Ensure that options 6 is set to none. 6. Select option 9 (Exit) to reboot the device. The streaming network settings will be configured when the VNM 250 device is connected to a network with a properly configured system controller or DHCP server.
Configuring a Windows 2008 R2. The windows DHCP server can be configured so that, when a VNM 250 device contacts the server for an IP address, the server can include the IP address of the system controller and the controller port number as part of the DHCP configuration. The figure below shows a Windows Server 2008 R2 installation. Other operating systems may vary.
Control Port The control port is used to access the web UI or the HLI control interfaces on a VN‑Matrix system. The web UI on either a VNM 250 device (configured as the system controller) or a VNM Enterprise controller may be accessed from any device on the same system by connecting a PC to a properly configured control port. This may be useful when a system is undergoing commissioning, but is not required for normal operation.
VNM 250 GUI Overview VNM 250 GUI Login The system can be configured and controlled using a graphical user interface (GUI), which is served by the VNM 250 device that is acting as the system controller. To use this GUI, follow these instructions: 1. Use one of the following web browsers with the version shown or later: zz Windows® Internet Explorer® version 8 zz Mozilla® Firefox® version 20 zz Google® Chrome™ version 30 The PC must be on the same network as the VNM 250 controller. 2.
VNM 250 GUI Tabs The following list shows the tabs that are available in the VNM 250 GUI control program and provides links to more detailed descriptions of each tab. They are divided into Shared tabs (encoder and decoder), Encoder tabs, and Decoder tabs. Configuration of the system, using the control program is described in Configuration with the VNM 250 GUI (see page 66).
Tabs Shared by Both the Encoder and Decoder Some of the tabs listed in this section, for example the Device List (see below), Accounts (see page 36), Alarms (see page 37), and Alarm Logs tabs (see page 38), can be accessed without first selecting a device. Other tabs, for example the License (see page 44), Upgrade (see page 40), and Peripherals (see page 41) tabs, can only be selected once a device has been selected.
Click on any of the text or icons for a specific device to open the Device tab for that device. For information about the encoder device tab, see page 45. For information about the decoder device tab, see page 57. Accounts tab — controller configuration From the Device List tab, click the Accounts tab: Figure 21. Accounts Tab The Accounts screen is used to change the passwords of the public and admin accounts, to update the system clock time, and to enter controller license details.
Clock Management NOTE: The Current Time is the date and time when the page was served. The Current Time is used by all devices to time stamp system events and alarms. The clock setting on all VNM 250 devices is factory set to UTC time and it is not necessary to make any changes to the setting for the system to operate. The clock setting may be changed to set the controller to local time, if required. New Time is the updated date and time.
Alarms can have three degrees of severity indicated by the alarm icons in the device list and the alarm status messages at the top of each page: zz Critical is shown in red and usually means the service has failed. If the device has a critical alarm it illuminates the red LED on the front panel and activates the closure relay accessed by the rear panel connector. zz Warning is shown in amber and indicates a less severe error has occured.
The system contains space for 200 alarm logs. Once more than this number of events have been recorded the history of older events will be discarded. Alarm Logs can also be cleared by clicking the Clear Logs button. Alarm logs can be sorted by type, raise time and severity by clicking on the column header. A small arrow shows the sort direction which is reversed when the column header is clicked a second time. The system has the capability to report an Alarm event via SNMP traps.
SNMP Community The value in the SNMP Community field acts as a password. It is used to authenticate messages between the VN-Matrix 250 system and the network management system (NMS). By default, the SNMP Community field is set to public. The SNMP Community string must match that in use by the NMS; if not, it may not be possible to manage the VN‑Matrix 250 device. SNMP Trap Destinations The Filter Settings dialogue on the Alarm Logs page is used to add and remove destination IP addresses for NMS servers.
Peripherals Tab To access the Peripherals tab, you must first select a device from the Device List and, when the Device tab opens, click the Peripherals Tab. Whether you navigate to the Peripherals tab from an encoder or a decoder, the functionality is the same. Figure 26. Peripherals Tab The Peripherals screen is used to manage the Coms pass-through serial port and the mouse+keyboard forwarding operation.
Pass-through mode In this mode, data received by a device (input) is transmitted over the network using TCP/IP and then converted back to serial data by a second device (output). Data flow is fully bidirectional and is independent of whether the VN-Matrix device is an encoder or decoder. Pass-through data cannot be recorded. One device in the pass-through group is designated the server. One or more devices are connected as clients (in pass-through mode).
Mouse+Keyboard Control VNM 250 products have the capability to forward Mouse and Keyboard information from a Display device to a Source device. This allows a Source (PC) to be controlled remotely from the Display location. The forwarding operation is configured automatically and the Display is connected to the Source from which video is currently being streamed. The user enables and disables M+K Forwarding by entering a hotkey sequence on the keyboard that is connected to the decoder.
License Tab Figure 28. License Tab Device License — for a VNM 250 device, the license features are fixed and cannot be modified.
Encoder Tabs Device Tab Figure 29. VN-Matrix Encoder Device Tab The Accounts and Alarms tabs disappear but Device, Upgrade, and Peripherals tabs appear, with the Device tab highlighted. In addition, there are three links (videoPort0, audioPort0, and data) in the Configuration panel. The encoder Device tab is split into four panels: Device Summary — provides information about the device: zz The device can be named by editing the Name text box and clicking Update.
zz Data interface is a read-only field that reports which of the CAT 5 (by default) or SFP connectors is currently active on LAN 2. zz Multicast TTL (Time to Live) defines the number of hops multicast traffic makes between routed domains when it exits a Source. Configuration — allows you to configure the video attributes of the source (VideoPort link), the audio attributes of the source (AudioPort link), the data attributes (Data link), or the display attributes and source selection.
The reported EDID drop down allows selection of the EDID that the encoder will report to the source device. Selecting Transparent mode reports the EDID from the currently connected monitor. If no monitor is connected, the EDID from the last connected monitor is used. EDID from previously connected displays is stored and may be selected. Alternatively, you may select one of the fixed EDIDs listed in the drop-down list. Available EDID files are shown in the Supported EDID Modes tables (see page 122).
Managing Compression and Bandwidth Settings From the Configure tab, click on the Bandwidth tab: Bandwidth Tab Figure 31. Video Bandwidth Tab The VNE 250 can apply various types of compression to an input source in order to reduce the volume of source data streamed across the network. In addition, various parameters are provided to manage and, if necessary, limit the amount of data flow to ensure that the available network bandwidth is not exceeded.
When the slider is set to unlimited, the bit rate depends on the complexity (detail and motion) of the source image. As the slider is adjusted to reduce the maximum bit rate, the encoder progressively drops frames in order to limit the instantaneous bit rate. The number of frames dropped depends on the source image complexity. NOTE: Extron advises against using more than 300 Mbps for most applications. Check with your network administrator to determine the available bandwidth.
Video quality and Bandwidth panel — advanced control Figure 34. Bandwidth Tab: Video Quality and Bandwidth Panel The Video Quality and Bandwidth panel (click More Detail, if necessary) provides a greater degree of control over the encoder compression settings. These controls are divided into two main categories: zz Video Quality zz Bandwidth They provide access to the complete set of image quality and bit rate tools for the VNE 250.
Bandwidth Panel Figure 35. Bandwidth Tab: Video Quality and Bandwidth Panel The VNE 250 can apply various control modes to manage the bit rate. These control modes are selected in the Mode drop-down list. None — no bandwidth management policy is followed apart from the underlying compression settings. Manual Frame Drop — allows the user to specify the precise fraction of frames to drop.
Video setup tab To access the Video Setup tab from the Bandwidth tab, click on the Configure tab and, when that opens, click on the Video Setup tab. The Bandwidth tab disappears and the Video Setup tab is highlighted. Figure 36. Video Setup Tab This tab provides access to advanced functions that will not be needed in a typical setup.
Audio Stream Configuration Configure (AudioPort0) tab To access the Configure (AudioPort0) tab, click on the Device tab and, when that opens, click on the AudioPort0 link in the Configuration panel. Figure 37. Configure (AudioPort0) Tab The VNM 250 product range supports both program and return audio. Program audio inputs may be analog or digital. The HDMI input supports 24 bit stereo PCM audio and AC-3 (Dolby 5.1) digital data at 44.1 kHz and 48.0 kHz sampling rates.
The following compression values are supported: Compression Stereo Audio AC-3 Audio no compression 24 bit native data (2975 kbps) 24 bit native data (2975 kbps) pack 24 bits 24 bit data, full sample rate (2250 kbps) 16 bit data, zeros run length encoded (430 kbps) pack 20 bits 20 bit data, full sample rate (1880 kbps) 16 bit data, zeros run length encoded (430 kbps) pack 20 bits 20 bit data, full sample rate (1880 kbps) 16 bit data, zeros run length encoded (430 kbps) pack 16 bits 16 bit dat
Analog output level (return audio) — a return audio source may be enabled using the Return Audio Source drop-down list. When enabled, return audio originates from a decoder that is receiving the program audio from this encoder. NOTE: The decoder return audio setting must also be enabled. This drop-down list is populated only when a program audio connection has been made to the decoder. The return audio can be muted and the output level adjusted using the Analog Output level control.
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 and VNR 100 devices. Two types of data are supported: zz Serial RS-232 data zz Serial UDP data Serial data transports are connected from encoder to decoder devices and are unidirectional.
Decoder Tabs Device tab Select a decoder in the Device List tab and click to open the decoder device page. 1 2 Figure 40. Decoder Device Tab The Accounts and Alarms tabs disappear but Device, Upgrade, and Peripherals tabs appear, with the Device tab highlighted. The decoder Device tab is split into four panels: Device Summary — provides information about the device (see figure 40 1): zz If required, the device is named by editing the Name text box and clicking Update.
zz Data interface is a read-only field that reports which of the CAT 5 (by default) or SFP connectors is currently active on LAN 2. zz Multicast TTL (Time to Live) defines the number of hops multicast traffic makes between routed domains when it exits a Source. If the TTL is not properly configured, information that is to be sent back to a corresponding encoder may fail to function correctly.
zz The Genlock control allows the display output of multiple decoders to be coordinated and creates a genlock group. One VND 250 device is selected as the timing reference for the output of all the other VND 250 devices in the same decoder genlock group. The genlock output from the chosen reference device is connected to the other decoders in a daisy chain architecture.
Each source is listed by the device name and videoPort name, and has a suffix that describes the connection type: zz _rtp — is an RTP unicast connection zz _rtp(m) — is an RTP multicast connection, if configured zz _tcp — is a TCP unicast connection Selecting a source with an _rtp suffix causes the decoder to connect to an RTP stream output by the selected source. The controller automatically connects the data stream to that decoder.
Decoder video bandwidth tab To access the video Bandwidth tab from the Device tab, click the Display0 link and, in the Display tab, click the video link. Figure 42. Video Bandwidth Tab This page provides statistics on the video stream and allows the decoder video buffer to be monitored and configured, if necessary. If required, modify the Window Name by editing the current value and clicking Update. It is not necessary to name this field for normal operation.
To synchronize channels, either between video and audio on one device or between video channels on multiple devices, the frame delay should be set to 6 and the channel delay to 0. Valid Delay settings can be determined by setting values then checking the Pipeline Status Meter. Setting is valid and should give a stable image. NORM LOW HIGH Playback delay is too small: the playback image jumps as network loading changes.
Figure 43. Audio Bandwidth Tab Audio output selection (Audio Control panel) Select the appropriate check boxes to output the received audio stream to the HDMI port, the Analog output port, or both. The HDMI output level cannot be controlled and is equal to the level seen on the encoder device. The analog audio output level is controlled using Analog Output Level. The output level will be correct if the input level on the encoder has been correctly configured for optimum signal level.
Decoder audio connection fields The decoder audio connection fields operate in the same ways as the video connection fields (see Decoder video connection fields on page 62). Decoder data bandwidth tab To access the data Bandwidth tab from the Device tab, click the Display0 link and, in the Display tab, click the data link. This page provides access to the data channel configuration settings.

Custom Input and Output Modes For most applications, the source input of the VNE 250 is set to auto mode. This enables the encoder to detect the electrical and timing characteristics of the input signal and determine the exact source type. It then invokes the appropriate input parameters for optimum processing of that source signal.
2 1 6 3 5 4 Figure 66. Advanced Video Setup For most source types select auto from the mode drop-down list (see figure 66, 1), allowing full auto-detection of the source. To apply a fixed input mode, select the required mode from the mode drop-down list and click Update or the Save All tab. NOTE: Selecting a fixed input mode disables the auto-detect function. Fine-tuning a source (manual overrides) The following adjustments are manual overrides of the selected source format.
If required, the calculated values for the first line and first pixel can be adjusted by applying a manual offset. To do this, set the blanking parameter to manual and type a positive or negative integer value into the pixels or lines fields as required, then click Update. NOTE: The offsets are made relative to the current source format “digFirstPixel” and “digFirstLine” values (see figure 65).
Constructing a custom user source format overview There are four basic steps to create a custom user source format: 1. Configure a source to display the unrecognized source format and connect it to the VN‑Matrix encoder. 2. Create a custom input mode to match the resolution and timing of the source. 3. Verify that the encoder can automatically detect (auto-detect) the source format created in step 2. 4. Fine-tune the custom input mode.
6. Select a source type similar to the desired source type in the Name field of the User Source Format panel (see figure 68, 1). If an existing (incorrect) mode was detected and displayed in the currentMode field of the Device Status panel, select that mode from the drop-down list. This acts as a baseline for the custom source format. 1 7 9 ¢ Figure 68. 2£ 3 6 4 8 5 User Source Format Panel 7. Click New Source (see figure 68, 2).
14. Enter the active horizontal resolution in the HSize field and the active vertical resolution in the VSize field (see figure 68, 9). 15. Copy the values in the digFirstPixel and digFirstLine fields of the Device Status panel to the FirstPixel and FirstLine fields (see figure 68, ¢). 16. Click the Update button (see figure 67, 1 on the page 80). The User Source Format settings are copied into the User.Source.Config file of the VN-Matrix device designated as the controller. 17.
Custom Output Modes The decoder Format tab allows you to create custom video output formats for displaying decoded video data streams. One of the issues encountered when some graphics sources are used in conjunction with VN-Matrix encoder and decoder systems is that the encoder often produces a loop-through image and states that it has detected a valid input mode. However, the decoder outputs a display splash screen that states “No Matching Output Mode.
17. From the source device that is supplying the encoder, change the resolution and allow the encoder to display the image on the loop-out. This forces the VN-Matrix to change both input and output modes. 18. Change the source back to the original resolution. If the image appears correctly on the decoder, the new mode that you created is working correctly. The mode creation is now complete and you can stop here.
2. Write down the values that are reported for: zz Active area width zz Active area height zz Frame rate zz Total line count zz Total pixels per line These values are required in the next section. Entering the timing values in the VN-Matrix web GUI 1. Return to the VN-Matrix GUI and open the decoder Format tab. 7 1 3 Figure 69. 2 8 4 5 6 2 Decoder Format Tab 2. In the Name drop-down list (see figure 69, 1), ensure that the mode you have just built is selected, then click Update. 3.
5. Calculate the horizontal back porch value. This value is calculated with the formula: total pixels per line – (active pixels in width + horizontal left border + horizontal right border + horizontal front porch + horizontal sync width) Using the values from the example in step 4, above, this equates to: 1800 – (1280 + 0 + 0 + 80 + 128) = 312 6. Enter this value into the Horizontal Back Porch field (see figure 69, 3). 7. Calculate the correct vertical values for the mode.
Upgrading Firmware Extron may issue firmware upgrades for the VNM 250 in order to make new functionality available. Details of the latest firmware release are published on the Extron website (www.extron.com). ATTENTION: The encoder and decoder each have a different firmware file. • Example of an encoder upgrade file name: 250_enc_ver5.3.16.tar. • Example of a decoder upgrade file name: 250_dec_ver5.3.16.tar. Ensure you load the correct file to each unit.
Uploading the Firmware File to the VNM 250 Controller 1. Log in to the web interface (see VNM 250 GUI Login on page 28). The GUI opens to the Device List page. 2. Click on the VNM 250 unit to be upgraded. The Device page for that unit opens. 3. On the Device page, click the Upgrade tab. The Upgrade tab opens: 3 12 5 Figure 70. 4 Upgrade Tab 4. Click Browse (see figure 70, 1) to open a file browser. Navigate to the required upgrade file, or type the path and file name directly into the browser field.
Configuring KVM Functionality KVM functionality permits remote collaboration between different endpoints on the network by allowing a mouse and keyboard connected to the decoder to control a PC connected to the encoder. Both the VND 250 and VNE 250 units must be configured. Before starting, ensure that a mouse and keyboard have been connected to the VND 250 and a PC has been connected to the VNE 250 (see USB Ports on page 17). 1.
RS-232 Pass-through Configuration The Coms port on the rear panel of the encoder (see figure 6, R on page 13), or decoder (see figure 7, R on page 13) is used for RS-232 pass-through communications, allowing a control device connected to one VNM 250 unit (the server) to control remote devices connected to other VNM 250 units (clients). Serial data received by one VNM 250 unit is transmitted over the network, using TCP/IP, and then converted back to serial data at the target VNM 250 unit.

Device Not Listed in the Device List Page Cause Check The device is not powered on. If the front panel LEDs are unlit and the front panel LCD menu is not cycling through the default menu, the unit is not powered on. Check that the power supply is connected to the rear panel receptacle and that the IEC cord from the power supply is connected to a suitable power source (see Power on page 14). If necessary, try using a different power supply unit.
Cause Check The loop-through display is incompatible with the input. Connect the source directly to the display and check that an image is shown. The VNE 250 does not The VNE 250 accepts VGA, DVI (with appropriate adapters), or HDMI signals. Other support the input signal video types are not recognized and cannot be streamed. format. In the web UI, check the status of the current mode and source status fields (see page 46) to ensure the source is recognized by the VNE 250.
Cause Check Power Save mode is enabled. The decoder display enters power save mode if the stream assigned for decoding is no longer available and the power save mode is enabled in the decoder front panel Output Sub-menu (see page 106) . No stream is assigned. Check that a video stream has been selected (see Assigning a video source stream on page 59). The Encoder is not correctly configured.
Return Audio Problems Return audio requires settings to be made on both the encoder and decoder. Cause Check The return audio input has not been enabled on the decoder. Ensure the Analog input enable check box is selected on the decoder bandwidth tab (see Return audio configuration on page 63). The return audio input level is not set correctly on the decoder. The input level is adjusted using the Analog input level text box on the decoder bandwidth page (see Return audio configuration on page 63).
