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,  
and mounting information. User guides are available at www.extron.com.  
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.

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).

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.
