Configuring the Nyquist VoIP Speakers
The Nyquist VoIP Ceiling Speaker Gen 2 (NQ-S1810CT-G2) and Nyquist VoIP Wall Baffle
Speaker Gen 2 (NQ-S1811WT-G2) are VoIP talkback speakers designed to work with the
Nyquist Series IP network-based intercom and paging solution.
The ceiling talkback speaker assembly consists of an 8" cone speaker and VoIP module
preassembled onto a 13" steel ceiling grille painted with bright white enamel.
The VoIP wall baffle talkback speaker assembly consists of an 8" cone speaker and VoIP
module preassembled onto a bright white injection-molded wall baffle speaker enclo-
sure.
Both types of speakers are 802.3af-compliant and are designed to facilitate rapid and effi-
cient deployment using existing network Power over Ethernet (PoE) ports. They also have
a Form-C relay for controlling third-party devices. These VoIP speakers enable ease of
placement wherever needed within a facility.
A two-second 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.

Standalone Operation
This device can also 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 allows this device it to be used without a Nyquist server as a
generic SIP endpoint when integrated with a 3rd-party VoIP telephone system or other
SIP server-based solutions, such as a unified communications (UC) platform. In a non-SIP
environment, these devices are capable of receiving audio through one or more priori-
tized multicast channels.
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 firmware
update occurs unless the Firmware parameter for the station is left blank. Refer to the
Nyquist System Administrator Guide for more information.

6
To use the Firmware Update page:
1On the appliance web UI’s main page, select Firmware Update to view or update the
firmware version.
• If the device is in Standalone mode, the Check for Updates button will be shown.
Selecting it 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 and the Update Firmware button will be shown.
• If 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 appli-
ance. 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.
The page displays the uploaded firmware version (“New Nyquist Version”) and an
Update Firmware button appears. Select this button if you want to update the
appliance’s firmware to the uploaded version.
• If you want to return your appliance to its original factory configuration, select
Restore Factory Settings.
• Select Reboot Appliance to restart your appliance.
Note: Some buttons only appear on this page when applicable.

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.
DHCP Enabled Indicates if the device is enabled to use DHCP to
retrieve its IP configuration.
Reboot Appliance Indicates that this appliance should reboot when the
