VNM Recorder • Setup Guide
The Extron VNM Recorder is a network storage device used to digitally record and
play back multiple streams of high resolution video, audio, and data encoded to an
IP network via VN-Matrix encoders and decoders. It can be used with any VN-Matrix
application to document, archive, review, and play back highly sophisticated or demanding AV imagery.
This guide provides basic instructions for an experienced installer to configure and operate a VNM Recorder using a basic
VN-Matrix system.
NOTE: See the VNM Recorder User Guide, VN-Matrix 200 Series User Guide, VN-Matrix 225 Series User Guide,
VN-Matrix 300 User Guide, and the VN-Matrix 325 User Guide for complete installation, network configuration,
Initial Installation and Configuration of Devices
Step 1 — Determine the Default Network Settings
Before connecting any device
to a network, the default
RS-232
RS-232
network settings of each
device must be changed. On
an existing network, check with
the network administrator for a
range of available IP addresses.

On a closed network, used
exclusively for VN-Matrix
devices, it is recommended
to use addresses within the
range of 192.168.254.1 to
192.168.254.254 with a subnet
mask of 255.255.255.0.

Figure 1 shows an example
addressing scheme for a simple system that contains a VNM Recorder, an encoder, and a decoder.
Step 2 — Determine the Device that Acts as the Controller
A device within the VN-Matrix system must be designated as the controller of the network. The controller can be one of the
following devices:
z
z
z
VN-Matrix 200, 225, 300, or 325 device, which is suitable for small network systems
VNM Recorder, which is suitable for small network systems
VNM Enterprise Controller, which is suitable for large network systems
The controller device acts as a central point of reference for each device, manages all of the system communications to
every matrix device present, and also serves the web-based control interface to the user. In figure 1, the VNM Recorder is set
up as the controller for the system. Once configuration of the VN-Matrix system is complete, the IP address of the controller
device can be entered into a suitable web browser running on any PC or laptop connected to the VN-Matrix network.
Step 3 — Install and Configure the VN-Matrix 200 / 225 / 300 / 325 Devices
Connect these devices as necessary and power them on. Configure the network settings of these devices using a PC running
HyperTerminal. For installation and configuration instructions, see the setup guides included with these devices. Figure 1
can also be used as a guide for configuring network settings.
Upper connector (eth0)
Step 4 — Connect the Recorder to the VN-Matrix Network
With the VNM Recorder positioned as shown in figure 1, connect the primary VN-Matrix network to the
upper Ethernet connector (eth0) of the recorder using Category (CAT) 6 cable. If necessary, connect a
secondary VN-Matrix network to the lower Ethernet connector (eth1) of the recorder using CAT 6 cable.
Lower connector (eth1)
Step 5 — Connect Configuration Devices to the Recorder
Connect a mouse, a keyboard, and a computer monitor to the recorder. See the VNM Recorder User Guide
for more information on connecting these devices.
Step 6 — Power on the Recorder
Plug a standard IEC power cord into the recorder and connect it to a power source. Power on the recorder.

g. Near the bottom of this file are two values named
st_controlIpand st_localIp0(see figure 4). Edit these
values as follows:
Edit this value to match
the IP address of the
controller device.
z
If the VNM Recorder is the controller device, edit both
values to match the IP address of the recorder.
z
If the recorder is not the controller device, change the
st_controlIpvalue to match the IP address of the
controller device. Change the st_localIp0value to
match the IP address of the recorder.
Edit this value to match
the IP address of the
VNM Recorder.
h. Save the config.xmlfile. Close the text editor window
Figure 4. Config.xml Text Window
and all other folder windows.
Step 9 — Restart the VNM Recorder and the VN-Matrix Network
Restart the VNM Recorder and all devices of the VN-Matrix system. Power down the recorder by pressing and holding the
power button on the front panel until the power LED turns off. This turns the recorder off instantly. After a few seconds,
turn the recorder back on.
Recording and Playing Media Files Using the Web-based User Interface
Step 1 — Access the Web-based User Interface
The web-based user interface can be accessed using a suitable web browser running on any PC or laptop connected to the
VN-Matrix network. Follow the steps below to access the user interface.
a. Navigate to the user interface by typing in the IP address of
the controller device into the address bar of a web browser
figure 5 appears in the browser.
NOTE: If the VNM Recorder is the controller device,
the IP address must be appended with the port
number that is used as the web server
b. Enter the appropriate username and password.
NOTE: By default, these are both set to admin. These
entries are case sensitive.
c. Click Log Inor press the <Enter> key. The Device List page
Figure 5. Controller Device Login Page
appears (see figure 6).
Figure 6. Device List Page
NOTES: • When system changes are made, it is recommended to click on the Save Alltab before logging out.
• To log out of the interface, click on the Logouttab or simply close the web browser.
• For more information on configuration and control options, click on the Helptab. The Helptab
provides detailed information for each web-based interface page and is a useful reference guide.
