Extron Electronics VN-Matrix 250 Setup Guide

VN-Matrix® 250 • Setup Guide

The Extron VN-Matrix (VNM) 250 Series consists of the VNE 250 encoder and
the VND250 decoder. They integrate into VN-Matrix systems to provide real-time
transmission of high resolution AV content across standard IP networks. The VNE250
encodes video or graphics sources at resolutions up to HD or 2K (2048x1080) using
the Extron PURE3™ Codec, a unique wavelet-based compression technology.
The VND250 decodes the content back to the original source resolution or a user
selected resolution. The VNM 250 Series offers real-time streaming and low latency, making it ideal for remote collaborative and
interactive or control applications. It can be deployed in live event streaming and high level conferencing for specialized projects.

NOTE: For full installation, configuration, and operation details, refer to the VN-Matrix 250 User Guide, at www.extron.com.

Before You Connect to a Network

Before connecting each VN-Matrix to a network, congure the network settings. On an existing network, check with the network
administrator for a range of suitable IP addresses.

VN-Matrix Controller

One VN-Matrix device in the system must be designated the controller. For large systems (ten or more devices) this must be a
VNM Enterprise Controller. For smaller systems (up to ten devices), the controller may be a VNM 250 device (either an encoder or
decoder). All system conguration is achieved via a web interface that is served up by the device acting as system controller.

Setup Procedure

Follow the instructions in the Connections and Initial Conguration sections for each individual VN-Matrix device, then follow the
Operation section instructions to create a VN-Matrix system. See the VN-Matrix 250 User Guide for more detailed information.

one or more VNM 250 devices will be connected to the equipment that is to be controlled (clients). Either the encoder or
the decoder can act as the server. Connect the three left pins of the RS-232 Coms port on the server (r) to the serial
port of a PC (pin 1 = Tx, pin2= Rx, and pin 3 = Ground).

b. Connect the three left pins of the RS-232 Coms port on the clients (

(pin1=Tx, pin 2 = Rx, and pin 3 = Ground).

7. Connections to the remaining ports on the VNM 250 units are optional. Follow the instructions provided in the VN-Matrix250

Series User Guide on www.extron.com.

After making the connections described above, you must congure the system. Initial, low-level conguration is described in the
next section. More advanced conguration requires system controller GUI control. See the VNM 250 Series User Guide.

Initial Configuration

1. Before starting, talk to your network administrator to obtain IP addresses for all units in the system.

2. Make connections for the low-level conguration of the VNM 250 unit. Connect the serial port of a PC to the three right pins

of the RS-232 Coms port (pin 3 = Ground; pin 4 = Tx; pin 5 = Rx).

NOTE: This connection is required for low level configuration only but not for normal operation. It does not need to

remain in place once the device is configured.

3. Open Extron DataViewer on the PC. In the opening dialog box, ensure the communications settings are:

●

Baud rate = 115200

4. When prompted, enter the login and password. By default both the login and password are config. The low level

conguration menu opens:
