Configuration Settings Tab Parameters

The easiest way to configure Nyquist appliances is to obtain configuration settings from the Nyquist server by selecting Get Configuration From Server. However, you can manually configure an appliance through the appliance’s Web UI when Standalone Operation is enabled (see "Standalone Operation Configuration Settings").

To view or manually configure the Nyquist appliance configuration:

1​On the appliance Web UI’s main page, select Configuration Settings.

2​View the settings as described in Table 5 for normal configuration, or modify the settings as described in "Standalone Operation Configuration Settings" for Standalone Operation configuration.

3​If changes were made (Standalone Operation only), click the Save Configuration Settings, Save Multicast Addresses (Transmit/Audiocast), and/or Save Multicast Addresses (Receive) buttons to save your changes.

The following table describes the Configuration Settings tab settings when Standalone Operation is not enabled for this device:

Table 5. Configuration Settings (Standalone disabled)

Get Configuration from Server | Retrieves configuration settings (i.e., web username, server, and local port) from the TFTP server specified in the Network Settings (see "Network Settings Tab Parameters").
Web Username | Displays the username of the current user.
Emergency-All-Call | Identifies the IP address, port number, cut level (volume), and station list used for emergency all-call pages.
All-Call | Identifies the IP address, port number, cut level (volume), and station list used for all-call pages.
Audio Distribution | Identifies the IP address, port number, cut level (volume), and station list used for audio distribution.
Multicast # | Identifies the IP address, port number, cut level (volume), and station list used for the multicast audio stream of a specific zone. If this device belongs to more than one zone, then multiple Multicast # entries will be displayed.
Nyquist Control Password | Specifies a password used to secure Nyquist control messages between this device and the Nyquist server. This value must match the password specified on the Nyquist server to support certain Nyquist features, such as sound masking, amp protection mode, and station check-in. The specified password must be exactly 20 characters long and include uppercase, lowercase, and numeric characters. Note: This password cannot be set unless the Web Password has been changed from the default value.

The Configuration Settings tab also displays the following information for each Device Station attached to the device:

Port Number | Shows the output port/channel number of the appliance.
Port Type | Shows the station type to which the port connects.
Account ID | Shows the SIP account (IP address) associated with the device preceded by the extension of the device associated with this port.
Local Port | Shows the port used for SIP.
Username | Shows the username or extension for the station associated with the port.

Standalone Operation Configuration Settings

Configuring this device consists of specifying one or more of the following:

The SIP server addresses, ports, and SIP extensions at which to register for incoming SIP calls.

The output unicast (Transmit/Audiocast) address and port to which the device will send the encoded signal that the device received (and encoded) from the specified line input channel.

The input unicast (Receive) port number at which the device will receive an encoded signal, which will then be converted to analog and played to the specified output channel(s).

The output multicast (Transmit/Audiocast) addresses and ports to which the device will send one or two encoded line input signals that the device received (and encoded) from the specified line input channels.

The input multicast (Receive) addresses and ports at which the device will receive one or more encoded signals, which will then be converted to analog and played to the specified output channels.

To receive networked audio from another GA400P device, configure a Unicast Address (Receive) entry with the unicast port on which to receive the encoded stream. (Note that an IP address need not be specified, as the device’s IP address will be used.) Specify a codec, output channel (i.e., Line Output channel), and cut level with which to play the received (and decoded) audio signal. To begin receiving the stream, set the Enabled field to Yes.

To receive networked audio over multicast, configure one or more Multicast Addresses (Receive) entries with the multicast addresses and ports on which to receive the encoded streams. Specify a codec, output channel (i.e., Line Output channel), and cut level with which to play the received (and decoded) audio signal. To begin receiving the stream, set the Enabled field to Yes.

To encode and transmit audio over the network to another device, connect a line-level audio source to one of the Line Input ports. To multicast the signal, configure the Multicast Addresses (Transmit/Audiocast) entry whose channel matches the line input port: specify a codec, cut level, and multicast address and port to which the signal will be streamed. That stream can be consumed by any devices configured to “listen” to the specified multicast traffic (signal). To begin transmitting the stream, set the Enabled field to Yes.

To configure the GA400P device to encode and transmit (unicast) audio over the network to another GA400P device (i.e., send directly to one IP address and port), configure the Unicast Address (Transmit/Audiocast) entry: specify the line input port from which to accept the signal, the codec with which to encode the signal, and the unicast IP address and port to which the encoded signal will be streamed. To begin transmitting the stream, set the Enabled field to Yes.

Important:​If Unicast Port (Receive) and/or Multicast Addresses (Transmit/Audiocast) are enabled, Unicast Address (Transmit/Audiocast) will be disabled and vice versa.
