Configuring the Nyquist VoIP Intercom
Module
Bogen’s plenum-rated Nyquist Voice over Internet Protocol (VoIP) intercom modules
transform any low-impedance analog speaker into a full-featured Power-over-Ethernet
(PoE) IP speaker. The modules use the latest technology to deliver superior audio quality,
making them perfect for IP paging and audio distribution. The built-in talkback capability
allows these modules to be used in VoIP intercom applications.
These 10-watt single-channel intercom modules are available with (NQ-GA10PV) or with-
out (NQ-GA10P) an HDMI video output, depending upon the application needs. They
also offer a CAN bus interface to work with the NQ-E7020 Digital Call Switch and a Form-
C relay for controlling third- party devices. Additionally, when paired with Bogen’s
ANS500M microphone module (optional), these intercom modules can be turned into an
ambient noise sensor to help maintain paging and background music intelligibility in
high-noise environments.
If an HDMI video device is attached, this device can display messages and images sent by
a Nyquist server, as well as a digital or analog clock. These messages can be used for
scheduled announcements, emergency instructions, automatically triggered messages,
simple ad-hoc messages, or many other purposes. If a Nyquist server is not present, the
device will display an analog clock and compatibility information about supported reso-
lutions. For further information on displaying and scheduling messages, see the “Manag-
ing GA10PV Display Messages” section of the Nyquist System Administrator Guide.
The Nyquist server or system controller can automatically discover and configure the
VoIP intercom module, but you can also manage the device, and manually configure
some settings, through the VoIP Intercom Module’s web-based user interface (web UI).
A short press of the appliance’s Reset button reboots the device. If you press the Reset
button for 10 seconds, the appliance returns to the factory default configuration settings.
Returning to the default configuration settings does not change the appliance’s firmware.
The following sections describe settings and configurations that can be applied to this device
which are not controlled by the Nyquist server. For information about using Nyquist’s auto-
matic configuration process, refer to the Nyquist System Administrator Guide.
To access the appliance’s UI:
1Access the appliance’s web UI by doing one of the following:
a) On your web browser, enter the IP address for the appliance as the URL.
b) From the Nyquist web UI navigation bar, select Stations, select Stations Status,
navigate to the device that you want to configure, and then select the Link icon.
Note: Do not use third-party Chrome browser extensions with the Nyquist user interface.

Standalone Operation
This device can run in Standalone Operation mode, where it will not interact with a
Nyquist server (e.g., E7000 or C4000). This means the device will not:
• Fetch device configuration from Nyquist server
• Register with Nyquist server (via SIP)
• Store backup information to Nyquist server
• Allow access to Nyquist server-based NTP
Standalone Operation mode is ideal for scenarios that do not require the full functionality
provided by an integrated system, such as the Bogen C4000 or E7000 Series, but has the
ability to provide paging, multi-channel audio processing, and a SIP endpoint for a PBX/
VoIP phone system. It can be used to play music, audio, paging, and related functions.
Updating Firmware
When you select Firmware Update from the appliance’s web UI, the Firmware Update
page appears. From this page you can determine which Nyquist firmware version the
appliance is using and if an update is available. You can also load a firmware release,
install the loaded firmware, restore the configuration to factory defaults, and reboot the
appliance.
Note: A Nyquist appliance connected to the Nyquist network receives a configuration
file from the Nyquist server that includes the latest firmware available from the server.
If the firmware is different from the one installed on the appliance, an automatic firm-
ware update occurs unless the Firmware parameter for the station is left blank. Refer to
the Nyquist System Administrator Guide for more information.

5
To use the Firmware Update page:
1On the appliance web UI’s main page, select Firmware Update to view or update the
firmware version.
2If the device is in Standalone mode, selecting the Check for Updates button checks
the Bogen website for the latest firmware version available. If a version newer than
the one currently installed is found, it is downloaded to the appliance.
3If you already have a firmware file you would like to install to the appliance, select
Upload Firmware to upload the firmware file from your computer to the appliance. A
popup screen appears that allows you to select the file that you want to upload. You
can navigate to the file’s location. After you select the file, select Upload.
4The page displays the uploaded firmware version (“New Nyquist Version”) and an
Update Firmware button appears. Select this button if you want to update the appli-
ance’s firmware to the uploaded version.
5If you want to return your appliance to its original factory configuration, select
Restore Factory Settings.
6Select Reboot Appliance to restart your appliance.

File Transfer Protocol (TFTP) server.
The specified TFTP server can be used to automati-
cally set this device’s Configuration settings via the
Get Configuration from Server button.
If TFTP Server from DHCP (see below) is set to “Yes”,
this value will be auto-configured via DHCP option
66, assuming the DHCP server has been configured
to provide option 66. For details, see the documenta-
tion for your DHCP server.
Note: A TFTP server runs on the Nyquist server on
port 69 (the standard TFTP port) and the optional
Nyquist DHCP service automatically provides this
TFTP address via option 66.
Note: If this value is unspecified, the TFTP Server
from DHCP will automatically be set to “Yes”, this
field will become read-only, and DHCP will be used to
configure this setting. To change this value, the TFTP
Server from DHCP setting must be set to No, which
makes the field editable.
Note: This setting is not available when Standalone
Operation is enabled.
TFTP Server from DHCP “Yes” means the device will use the DHCP option 66
value to retrieve an address for the TFTP Server from
DHCP.
“No” means the device will ignore the DHCP option
66 value and use the manually configured value of
the TFTP Server (see above).
Note: This setting is not available when Standalone
Operation is enabled.
