Connections

Power

The provided 12 VDC, 3 A power supply connects to

2.0 A MAX

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: Electric shock hazard — The

two power cord wires must be kept separate

while the power supply is plugged in. Remove

power before wiring.

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 and note boxes below).

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.

• 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.

• This product is intended for use with a UL Listed power source marked

“Class2” or “LPS” and rated 12VDC, minimum 3.0 A.

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

Never use it to power multiple devices.

• The power supply shall not be located 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.

• 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.

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

structure.

• 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.

• 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.

NOTE: Do not tin the wires. Tinned wire does not hold its shape and can become

loose over time.

Network Connections

The VNM 250 series units have two separate network

connectors: one for the control network (LAN 1) and the

other for the streaming network (LAN 2). Each port has

its own IP address.

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.

NOTE: By default, only the LAN 2 RJ‑45 connector is populated 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

on page 13 for the encoder or figure7,

C

on

page 13 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. Choose a suitable SFP connector (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. When a compatible SFP

module is installed, the SFP port becomes active and the RJ‑45 port is deactivated.

3. Connect a single mode or multi‑mode cable to the encoder (see figure 6,

D

on page

13), or decoder (see figure7,

D

on page 13).

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 24).

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

on page 13), or decoder (see figure7,

C

or

D

on page 13).

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

4. Type in 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 Device as the System Controller on page 27).

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 may be used for system control, using the HLI control protocol. A

touchpanel or similar control interface may be connected and configured to communicate

with the VNM Enterprise Controller to recall previously configured presets.

NOTE: This control method may 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).

USB Ports

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

1

ports (see figure7,

F

on page 13).

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.

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 33).

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 89).

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 89).

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.

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.

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

z One device in each pass‑through group is designated as a server.

z One or more devices are connected as clients.

z There may be more than one pass‑through group in a system.

z A pass‑through group may consist of all encoders, all decoders, or a mixture of both.

z A device may 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.

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

VN‑Matrixrecorder.

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

affected by the commands.

z 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 will be the server in the pass‑through group and which will

be the clients.

Tx Rx

GTxRx

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.

PASS THRU CONTROL

Use the first three poles of a shared captive screw connector

(Tx, Rx, and G). See the Attention and Note boxes on page 14

for information about preparing and connecting wires to a captive screw connector.

3. Log in to the web interface (see VNM 250 GUI Login on page 33).

4. Configure the server (see Pass-through Coms Server Configuration on page 90).

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

page 90).

RS-232 control

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). See

the Attention and Note boxes on page 14 for information about

preparing and connecting wires to a captive screw connector. See

Low Level Device Configuration on page 24.

NOTE: The RS‑232 pins are not in the standard Extron

orientation. Ensure that the connector is correctly wired (see

the figure to the right).

Alarms

Alarm relays — provide a normally open (NO) contact. Use the first

NO GINGOUT

two poles of a shared captive screw connector (see figure 6,

S

or

figure7,

S

on page 13). See the Attention and Note boxes on

I/O

page 14 for information about preparing and connecting wires to a

ALARM GENLOCK

captive screw connector.

TTL

TTL (VNE 250) —the TTL (Transistor‑transistor logic) feature is not

currently supported.

Genlock

Genlock I/O (VND 250) —is used to synchronize the video output

on multiple decoders.

NOTE: The VND 250 uses TTL level signalling, which is not

compatible with normal genlock sources.

One decoder is selected as the reference (master) unit, and provides the signal that is used

to synchronize all the other units (slaves).

1. Configure one decoder as the Master unit, using the web‑based GUI control program

(see Genlock on page59).

2. Configure all the other decoders as slaves by selecting the Genlock check box of the

web‑based GUI control program (see page 59).

3. Connect the Ground connector of the master unit to the ground connector of the first

slave device.

4. Connect the Out connector of the master unit to the In connector of the first slave

device.
