Administration

What you should know

  • Your network may be overloaded by the wrong settings made in this tab.
  • Access via API is limited to 10 clients by default. 
  • Multicast is disabled in 2N IP Audio System by default.
  • Trace can be saved and used for troubleshooting in your 2N Telekomunikace a.s. Technical Support communication.
  • The scanner allows you to see 2N® Net Audio Decoder or 2N® Net Speaker even if 2N® Net Audio Decoder or 2N® Net Speaker does not obtain the IP address from the network. For a proper function you have to assign the IP address manually in this case. This, however, works in switched networks only.
  • Virtual Network adapters may cause malfunction of the Net Audio device scanner.

The Administrator tab helps you set other 2N IP Audio System parameters and monitor the state of the system. The tab contains general settings and administration.

 

General Settings

General

General allows you to set the Control Panel language and external syslog server for logs.

The language can be chosen by the Application language selector.

The SYSLOG server is used for sending the 2N® IP Audio Manager logs onto an external Syslog server. After the IP address and destination port are set, the server messages will be sent automatically. The TCP protocol is used for packets and therefore it is necessary to enable TCP connection on your syslog server.

Audio Devices

Audio devices allows you to select the local sound device for listening in. Listening in is a capability to listen to sessions locally, which makes troubleshooting easier. Select the device to which the sound will be routed. These devices depend on the PC configuration.

 

Sessions

Sessions allows to set more session parameters.

  • Show sessions from connected consoles – view even sessions that are created by the Console and Player users with the Freeride privilege.

Licences

This tab is used for licence administration. Licences are obligatory for advanced functions of the 2N IP Audio System. The licence will keep valid after your PC Windows/HW upgrade. In any case contact the Technical Support.

Without a licence you can use up to 5 2N® Net Audio Decoder/2N® Net Speaker devices and 1 RTP destination. By default, an 800-hour trial licence is active and allows you to use all features of the 2N IP Audio System system without any limitations.

Licence Settings

Network Settings

Interfaces

Set the network interface for communication. The selected network interface is used for multicast scanner, RTP and multicast transmission.

 

Multicast Addresses

Set the multicast addresses. Select multicast for the address range, multicast for the port range or single IP address transmission. The default address scope is 239.0.0.0/8. The figure below shows the default setting for the address range. If the range of addresses is set, then multicast is used. Each group of speakers with the same settings (session, delay, bitrate...) use one multicast stream.

The TTL parameter allows to change time to live for multicast packets. Use -1 to ensure that the system default is used! Some special 2N IP Audio System applications require a change of these settings but it should be done only in cooperation with a network specialist.

 Multicast Setting Options

API

The API settings helps you set the port for 2N IP Audio System API connection and client restriction.

XML API allows an external 3rd party application (e.g. iPhone application, tablet application) to control the system. HTML API allows to send basic commands to the 
2N® IP Audio Manager and control sessions. HTML API is primary used by VoIP phones or intercoms but the command can be also sent from a web application.

Proxy

The Proxy settings help you use an external HTTP Proxy. 

 

Caution

  • When you make a change, restart the service (2N® IP Audio Manager).

Database

Database displays database tables. Changes of the DB parameters are possible but reckless changes may corrupt the 2N® IP Audio Manager!

The Cfg_PollTout parameter in the MSGBT_CHAN table sets the communication timeout. A 2,500 ms timeout is set by default and 4x2,500 ms represents a timeout for communication between the 2N® IP Audio Manager and the 2N® Net Audio Decoder/2N® Net Speaker devices or 2N® IP Audio Control Panel. This parameter can improve the 2N IP Audio System performance in networks with complicated structures.

The Cfg_Port parameter in the MSGBT_LL_TCPSRV table allows you to change default ports for incoming communication from the 2N IP Audio devices to the 
2N® IP Audio Manager (port 6999) and from the 2N® IP Audio Control Panel to the 2N® IP Audio Manager (6990). If a change of this parameter is made on the server side, it has to be made on the client side too.

The NTPQueryTimeout parameter in the NSPK_SRVT_GLOBAL table allows you to change the time synchronisation timeout. This parameter can improve the 2N IP Audio System performance in networks with complicated structures.

The NSPK_SRVT_STATS_SND_BUFFER table shows statistical data on communication for short (10s - 60s) and overall time periods.
