About this Guide

The VN-Matrix 250 (VNM 250) series consists of the VNE 250 encoder and the VND 250
decoder. This guide contains installation, configuration, and operating information for both
the encoder and the decoder.

In this guide:

• The terms "VNM 250" or "VNM" can refer to either the VND 250 or VNE 250.

• The term "encoder" refers specifically to the VNE 250 encoder.

• The term "decoder" refers specifically to the VND 250 decoder.

• The term "stream" refers to multimedia that is constantly received by (and normally

presented to) an end-user while being delivered by a VN-Matrix encoding device.

About the VNM 250

The VNE 250 distributes video, audio, and data input across an IP network to one or more
VND 250 decoders. Transport across the network must be coordinated by a control device.
For a small system (ten devices or fewer connected to the network) the controller can be
either a VNM 250 encoder or decoder. For larger systems, aVNMEnterpriseController is
required.

The VNE 250 encodes video, audio, and data inputs into PURE3 data streams for transport
across a local area or wide area network. Elsewhere on the network, one or more VND 250
units decode the stream.

VNE 250 inputs can include:

• Analog (VGA) video

• Digital (HDMI) video

• Analog audio

• Digital audio that is contained in an HDMI signal

• Serial (RS-232) and UDP data

• USB connections for remote mouse and keyboard

The individual video, audio, and data streams are synchronized and treated as a single
logical stream.

VNM 250 • Introduction 1

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.

User Datagram Protocol (UDP) network data originating from an external source is streamed
along with the video and audio content to the appropriate decoder, where it is extracted for
onward processing.

RS-232 pass-through data transport is full duplex. It can originate at either the encoder or
decoder and may be sent to multiple destinations. It passes through the system unchanged
and may not be recorded.

Figure 1 shows a typical application for the VNM 250.

Figure 1. A Typical VNM 250 Application

NOTE: In the setup shown in figure 1, an Extron touchpanel is connected to the LAN-1

port of the VND 250.

Once the touchpanel is connected to the LAN-1 port of VNM 250, the IPLink
controller can receive commands from the touchpanel but can no longer update the
touchpanel configuration.

This setup requires all configuration of the IPLinkcontroller and the touchpanel to be
completed before the touchpanel is connected to the VND250.

VNM 250 • Introduction 2

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

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).

The system is controlled through a powerful
web-based user interface served from the
Enterprise Controller. An HLI interface is also
provided for control via an external control
system.

Supports all VN-Matrix devices, including
recorders.

NOTES:

• A small system that includes a VNM 250 device must be controlled by either a

VNMEnterprise Controller or a VNM 250 device.

• If an incompatible VN-Matrix device is added to a small system controlled by a

VNM250 device, the controller is unable to detect or control that device.

Transport Protocols Used for Streaming

The source data from a VN-Matrix encoder can be distributed to multiple displays/decoders
(one-to-many) or to a single display/decoder (point-to-point). A previously recorded stream
can be distributed in the same way and can be thought of as an encoder in this context.

A stream can be transported from the source (encoder, recorded stream) to the display
(decoder) using one of three methods:

• See Multicast RTP — An Overview on page 4.

• See Unicast RTP — An Overview on page 5.

• See TCP — An Overview on page 5.

Systems Controlled by VNM250Device

A VNM 250 device can control small systems
(10 devices or fewer). It is less effective as the
system size increases.

The system is controlled through a more
limited web-based user interface served from
the VNM250 controller device.

Supports VNM 250 encoders and decoders
and PCs running the VNS 104 software
decoder. Does not support recorders.

Figure 2. Multicast RTP Streaming

The source encoder uses RTP to send data to a multicast group. The source does not need
to know the IP address of the decoders that are using the source.

RTP provides very low latency which is important for video streaming. Unlike other
protocols, RTP packets include a time stamp. If packets are received in the wrong
order, they are sorted into the correct order for display or discarded if the time stamp is
out-of-date.

However, because RTP is a connectionless protocol, data delivery is not guaranteed.
When data packets are lost (for example, due to excessive network traffic), the
VNM 250 devices carefully manage the data stream to minimize any image disruption.

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. This means that the

total bandwidth of the VN-Matrix system increases as more decoders are added.

When data packets are lost (for example, due to excessive network traffic), the
VNM 250 devices carefully manage the data stream to minimize image disruption.

TCP — An Overview

This method transports data using standard TCP (Transmission Control Protocol) and
should only be used for single point-to-point transfer of data.

TCP is a connection-based protocol and, therefore, data is guaranteed to be delivered.
However, in the event of excessive network traffic, delivery can be delayed which impacts
real-time performance. Therefore, TCP transport should be avoided for streaming
applications.

VNM 250 • Introduction 5

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.

• PURE3 streams always contain video or graphic elements.

• PURE3 streams can also contain audio and data content that is associated with the

video and graphic elements.

• Media (stream) — refers to multimedia that is constantly received by (and normally

presented to) an end-user while being delivered by a streaming provider. Internet
television is a commonly streamed medium. Streaming media (stream) in this guide
refers to a PURE3 media stream that is produced by a VN-Matrix encoding device.

• Device license — refers to the number of licensed features that are available on a

device within a VN-Matrix system. All devices contain a license that offers a default level
of functionality. Device licenses cannot be modified.

• Controller license — refers to the license that is set on the device designated as

the system controller. The controller license enables the use of VN-Matrix software
decoders. Controller licenses can be modified to suit changing system requirements.

• UDP data — refers to the transfer of serial data between an encoder and a decoder.

Data input is created at the encoder, placed into the PURE3 stream, and sent to the
decoder. The data is received in the same form that it was transmitted. This method of
data transfer is unidirectional and can only be sent from an encoder to a decoder.

• High-Level Interface (HLI) — is the command protocol that is used to communicate

between the VNM Enterprise Controller and an external control system.

• Display Monitor Timings (DMT) — is a list of VESA standard pre-defined timings

which are commonly used within the computer industry.

• Coordinated Video Timings (CVT) — is the newest VESA standard for generating

display timings (released on March 2003).

• Generalized Timing Formula (GTF) — is a method of generating industry standard

timings used by a wide variety of display products.

• Simple Instruction Set (SIS) — SIS Commands (see page 126) consist of strings

(one or more ASCII characters per command field) that are used to communicate
between a control device and an Extron product.

Features

• Stream at native resolutions up to 1920x1200 and 2048x1080 — compatible with

signals used in high-resolution display applications.

• Low latency streaming — 35 ms encode and 35 ms decode — supports natural

interaction, bidirectional communication, or remote device control in real-time operating
environments.

• SFP port for use with optical Ethernet transceivers — provides the option to use

an optical Ethernet network interface to optically isolate a source or eliminate electro­magnetic emissions in secure applications.

• Extensive bit rate management — uses compression and bit rate management

controls to tune image quality and bit rate to fit a variety of application and network
requirements.

• High immunity to network errors — AV streaming maintains reliable, high-quality

imagery, concealing errors even during heavy packet loss.

VNM 250 • Introduction 6

• Unicast or multicast streaming — supports scalability and compatibility with different

network operating conditions.

• PURE3 Codec — low-latency, visually lossless compression offering efficient bit rates,

and high immunity to network errors for streaming very high quality video with low delay
over IP networks.

• 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.

• EDID emulation — provides selectable resolutions and refresh rates, ensuring optimal

resolution and format between video sources, encoders or decoders, and displays.

• Auto-Image setup — when activated, the unit automatically detects the resolution

of the incoming video signal and sets the total pixels, active pixels, and active lines, as
well as the horizontal and vertical starting points. This can save time and effort in setting
up a newly connected source, particularly in presentation environments where the
input is not connected to a fixed source, but instead goes to an open connection for a
presenter’s laptop.

• Decode at native resolution or scale to match display resolution — configure

decoders to output the original source resolution or to scale incoming streams to
match the display resolution and maintain clean switches when new source streams are
selected.

• Aspect ratio control — the aspect ratio of the decoder output can be controlled by

selecting a FILL mode, which provides a full screen output, or a FOLLOW mode, which
preserves the original aspect ratio of the original source signal.

• HDMI compliant — both the encoder and decoder support RGB and YCrCb source

formats.

• HDCP compliant streaming — supports streaming of HDCP-encrypted signals

commonly used in AV environments.

• Key Minder continuously verifies HDCP compliance — authenticates and

maintains continuous HDCP encryption from sources to encoders and decoders to
displays ensuring reliable streaming of HDCP compliant displays.

• HDCP Visual Confirmation provides a green signal when encrypted content is

sent to a non-compliant display — a full-screen green signal is sent when HDCP­encrypted content is transmitted to a non-HDCP compliant display, providing immediate
visual confirmation that protected content cannot be viewed on the display.

• Audio —the VNM 250 incorporates:

• Bidirectional audio streaming. Two-way audio streaming supports bidirectional

audio communication between encoders and decoders.

• HDMI embedded audio and analog stereo encoder inputs.

• HDMI audio embedding or de-embedding by decoder. Audio signals can be

embedded onto the HDMI output signal or extracted to the analog stereo output.

• Audio breakaway streaming. Stream audio to decoders independently of associated

video sources. (This feature requires a VNM Enterprise Controller.)

• Alarm relay — provides contact closure notice of warnings or alarms to control

systems for proactive system monitoring and fault resolution.

• Front panel LCD interface, buttons, and rotary encoders — provide access and

control over device status and system data, simplifying system setup and operation.

VNM 250 • Introduction 7

• Front panel LEDs — offers quick visual indication of device, system, or streaming

status to simplify commissioning activities and troubleshooting.

• VLAN tagging — simplifies management of encoders and decoders, making

management and operation on multi-purpose networks simple.

• Local Ethernet control port — offers the flexibility to connect a control device to the

VN-Matrix 250 unit simplifying network cabling for the streaming system.

• USB connector 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 port allows 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.

• On-screen display — aids in identifying system connections and simplifies

troubleshooting and programming activities.

• System management with VNM Enterprise Controller — simplifies management

and control of systems with many VN-Matrix devices.

• Compatible and interoperable with VN-Matrix 200 and VN-Matrix 225 models —

preserves the value of prior investment in VN-Matrix products.

• Serial RS-232 data streaming — manage RS-232 serially-controlled devices across

VN-Matrix 250 connections.

• Smart power management for encoder, decoder, source, and display

operation — configure encoder, decoder, or display to manage operation and sleep
mode for continuous operation or energy management, lowering heat, and saving
energy and operating costs.

VNM 250 • Introduction 8

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 (LAN 2) on page 17).

2. Select a suitable location and mount the VNM 250 devices (see Mounting on

page 130). Depending on your system, there may be multiple locations and multiple
units at each location.

3. Power on the VNM 250 devices by connecting the provided power supplies (see Power

on page 14). Do not connect the devices to a network.

4. Decide which device is the system controller. For large systems (more than 10devices),

you must use a VN-Matrix Enterprise Controller. To configure the system using the
Enterprise Controller, see the VN-Matrix Enterprise Controller User Guide at www.

extron.com.

For smaller systems, you can use the Enterprise Controller or a VNM250 unit as the
controller (see Low Level Device Configuration on page 25).

5. Connect the Control connector of the rear panel Coms port (three poles of the 5-pole

captive screw connector) to a control computer. Use DataViewer to configure the IP
addresses for both the control port and streaming port, the subnet mask, and gateway
for each unit (see Low Level Device Configuration).

ATTENTION:

• Prepare thoroughly before connecting or configuring the VNM250 for an

existing network. Contact your network administrator to ensure you have the
correct network information for each device that is being added to the network.
Incorrect connection or configuration may disrupt the network.

• Préparez minutieusement avant toute connexion ou configuration le VNM250

pour un réseau existant. Contactez votre administrateur réseau pour vous
assurer que vous détenez les bonnes informations relatives au réseau pour
chaque appareil relié au réseau. Une connexion ou configuration incorrecte est
susceptible de perturber le réseau.

NOTE: Extron recommends configuring the IP addresses through the Coms port on

the rear panel. Alternatively, it is possible to use SIS commands (through the USB
port on the front panel) or the front panel menu.

VNM 250 • Installation Overview 9

6. Connect all the VNM 250 units to the network (see Network Connections on

page 16).

NOTES:

• Ensure that the LAN 2 port is connected to the designated streaming network.

• The control port is used with IP Link or third-party control devices. A control

port connection is not required for normal operation of the VNM 250 unit.

7. Connect the video sources to the encoders and display equipment to the decoders (see

Video Connections on page 21).

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 22).

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 (see page 18). This allows

users at the decoder site to take control of the keyboard and mouse of the source
computer at the encoder site.

10. If required, connect the encoder loop-through video (see Video Connections) and

audio (see Audio Connections) outputs.

11. If required, set up Genlock connections (see page 20) to synchronize the video

streams to multiple displays.

12. Use a PC or laptop to access the web interface served by the controller.

For larger systems, see the VN-Matrix Enterprise Controller User Guide. For smaller
systems, see VNM 250 GUI Overview on page 34.

13. Configure the video and audio input and output properties for all the devices, using the

appropriate GUI web interface.

NOTE: Extron recommends configuring the audio and video connections through

the GUI web interface. Alternatively, it is possible to use the front panel menu.

The provided 12 VDC, 24 watt power supply connects to a 2-pole, 3.5mm captive screw
receptacle on the rear panel of the encoder (see figure 6, A on page 13), or decoder
(see figure 7,A on page 13).

1. Connect the captive screw connector from the power supply to the power receptacle.

CAUTION: The two power cord wires must

be kept separate while the power supply is
plugged in. Remove power before wiring.

ATTENTION : Les deux cordons

d’alimentation doivent être tenus à l’écart
l’un de l’autre quand l’alimentation est
branchée. Couper l’alimentation avant de
faire l’installation électrique.

2. Connect the AC power cord of the power supply

unit to a 110 or 220 VAC electrical source.

If it is necessary to wire the captive screw
connector, ensure the polarity of the wires is
correct (see the figure to the right).

Ensure the wires are stripped correctly (see the
attention notifications below and on the next page).

ATTENTION:

• Always use a power supply provided by or specified by Extron. Use of an

unauthorized power supply voids all regulatory compliance certification and
may cause damage to the supply and the end product.

• Utilisez toujours une source d’alimentation fournie ou recommandée par Extron.

L’utilisation d’une source d’alimentation non autorisée annule toute certification
de conformité réglementaire, et peut endommager la source d’alimentation et
l’unité.

• Extron power supplies are certified to UL/CSA 60950-1 and are classified as

LPS (Limited Power Source). Use of a non-LPS or unlisted power supply will
void all regulatory compliance certification.

• Les sources d’alimentation Extron sont qualifiées UL/CSA60950-1 et sont

classéesLPS(LimitedPowerSource). L’utilisation d’une source d’alimentation
non-listée ou non-listéeLPS annulera toute certification de conformité
réglementaire.

• If not provided with a power supply, this product is intended to be supplied by

a UL Listed power source marked “Class 2” or “LPS” and rated output 12Vdc,
minimum 2.0 A minimum.

• Si le produit n’est pas fourni avec une source d’alimentation, il doit être

alimenté par une source d’alimentation certifiée UL de classe 2 ou LPS, avec
une tension nominale 12 Vcc, 2 A minimum.

• The power supply provided must only be used with a single VNM 250 device.

ATTENTION:

• These power supplies are not suitable for use in air handling spaces or in wall

cavities. The power supply is to be located within the same vicinity as the
Extron AV processing equipment in an ordinary location, Pollution Degree 2,
secured to the equipment rack within the dedicated closet, podium, or desk.

• Ces sources d’alimentation ne sont pas appropriées pour une utilisation dans

les espaces d’aération ou dans les cavités murales. Cette source d’alimentation
doit être située à proximité de l’équipement audiovisuel d’Extron, dans un
endroit ordinaire avec une pollution IEC1010 degré2, et fixé à un équipement
de rack au sein d’un placard, d’une estrade ou d’un bureau qui lui est dédié.

• The installation must always be in accordance with the applicable provisions of

National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16.

• Cette installation doit toujours être en accord avec les mesures qui s’applique

au National Electrical Code ANSI/NFPA70, article725, et au Canadian
Electrical Code, partie1, section16.

• The power supply shall not be permanently fixed to building structure or similar

structure.

• La source d’alimentation ne devra pas être fixée de façon permanente à une

structure de bâtiment ou à une structure similaire.

• If a power strip is used, for example within rack-mounted installations, ensure

that the current rating for the power strip and the supply is sufficient for all the
equipment within the rack.

• Si une multiprise est utilisée, pour des installations montées en rack, à titre

d’exemple, assurez-vous que le courant nominal pour la multiprise et la source
d’alimentation soit suffisant pour tous les équipements du rack.

• The length of the exposed wires in the stripping process is critical. The ideal

length is 3/16 inch (5 mm). If it is any longer, the exposed wires may touch,
causing a short circuit between them. If it is any shorter, the wires can be easily
pulled out even if tightly fastened by the captive screws.

• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les

dénuder. La longueur idéale est de 5mm (3/16inches). S’ils sont trop longs,
les câbles exposés pourraient se toucher et provoquer un court-circuit. S’ils
sont trop courts, ils peuvent être tirés facilement, même s’ils sont correctement
serrés par les borniers à vis.

• Do not tin the wires. Tinned wires are not as secure in the captive screw

terminals and could pull out.

• Ne pas étamer les câbles. Les câbles étamés ne sont pas aussi bien fixés dans

les borniers à vis et pourraient s’arracher.

STREAMING CONTROL

See figure 6 or figure 7, B, C, and D.

The VNM 250 series units have two separate network
connectors: one for the Control network (LAN 1) (see
page 17) and the other for the Streaming network

(LAN 2) (see page 17). Each port has its own IP

address.

The control port (LAN 1) is not required for normal
operation. When necessary, this port can 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.

NOTE: By default, only the LAN 2 RJ-45 connector is present and available for use. If

an SFP connector is required, it must be purchased and installed by the user. When
installed, the SFP connector becomes the active port and the RJ-45 connection is
inactive. Both of the LAN 2 ports share the same IP address.

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.

To use the RJ-45 port (see figure 6, C for the encoder or figure 7,C for the decoder),
connect this port to the network with a standard LAN cable.

If required, third-party SFP connectors must be purchased separately. To install an SFP
connector, follow these points:

1. Select and purchase the SFP connector that is most suitable for your requirements

(most models are acceptable). Either singlemode (1310 nm) or multi-mode (850nm)
modules can be used.

2. Power down the unit. In addition to being good safety practice, the unit needs to be

rebooted for the device to correctly recognize the SFP port.

3. Install the module and reboot the unit. When a compatible SFP module is installed, the

SFP port becomes active and the RJ-45 port is deactivated.

4. Connect a single mode or multi-mode cable to the encoder (see figure 6, D), or

decoder (see figure 7,D).

To use a VNM 250 device as a controller:

1. Configure the network settings of the device that is to be used as the system controller

(see Low Level Device Configuration on page 25).

2. Connect the device to the network using the streaming LAN 2 port on the rear panel of

the encoder (see figure 6, C or D), or decoder (see figure 7,C or D).

3. Open a web browser on a control PC that is connected to the same network.

4. Enter the IP address of the streaming port of the VNM 250 device that was set as

system controller in step 1, above, and use the GUI to configure the system settings
(see Setting a VNM 250 Device as the System Controller on page 28).

NOTE: To control larger systems (ten or more components), use a VN-Matrix

EnterpriseController (see the VN-Matrix Enterprise Controller User Guide at

www.extron.com).

Control network (LAN 1)

The control port LAN 1 can be used for system control, using the HLI control protocol. A
touchpanel or similar control interface can be connected and configured to communicate
with the VNM Enterprise Controller to recall previously configured presets (see the Note
under figure 8 on the previous page).

NOTE: This control method can only be used with a VN-Matrix Enterprise Controller.

The HLI control protocol is not supported by the VNM 250 controller (see the
VN-Matrix Enterprise Controller User Guide at www.extron.com).

KVM function

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 using the rear panel USB ports.

1. Connect a mouse and keyboard to the VND 250 rear panel USB

ports (see figure 7,F on page 13).

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.

3. If the system is controlled by a VNM Enterprise Controller, use the Enterprise Controller

GUI for configuring KVM functionality (see the VNM Enterprise Controller User Guide at

www.extron.com).

If a VNM 250 device is the system controller, use the GUI for that device to configure
KVM functionality (see VNM 250 GUI Overview on page 34).

Both the encoder and decoder must be configured to allow KVM functionality, using
the Peripherals page of the web user interface of the device being used as system
controller (see Configuring KVM Functionality on page 90).

Once configured, the KVM mode is activated using a hot key sequence on the keyboard
that is connected to the decoder (see To activate a remote control session using

hot keys on page 90).

4. Configure the system so that the decoder is viewing the source PC.

NOTE: KVM is only available when there is an active video stream between the

encoder and decoder.

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.

Units that are configured for this type of data flow are called pass-through groups:

• One device in each pass-through group is designated as a server.

• One or more devices are connected as clients.

• There may be more than one pass-through group in a system.

• A pass-through group can consist of all encoders, all decoders, or both.

• A device can be a server or client independently of whether it is an encoder or decoder

and independently of whether or not it is the system controller.

• Pass-through data is not part of the media stream and cannot be stored by a

VN-Matrixrecorder.

• Data passes through the system unchanged (transparently). No VNM 250 devices are

affected by the commands.

• The serial ports on different devices do not need to share a common baud rate.

However, if a large amount of data is sent from a high speed to a low speed data link,
some form of handshaking or flow control may be required to prevent buffer overflow on
the output device. Standard flow control methods are fully supported.

To set up the RS-232 pass-through group:

1. Decide which VNM 250 unit is the server in the pass-through group and which are the

clients.

2. Connect your serial devices to the VNM 250 RS-232 ports

accordingly. Communication can only take place between server

and client, not between clients.

5. Configure one or more clients (see Pass-through Coms Client Configuration on

page 91).
