IP Audio Interface Installation | en 13 No DHCP server is found 4.5.1 If no DHCP server is found then the built‑in IPzator function will search the network for a free IP address. This can take up to 5 minutes. If the IP address is not announced, check: – If the green LED on the network port used (13 or 14) is ON. When OFF, check your network cabling. – The green status LED (2). When OFF, check the power supply cabling.
en | Connection options 5 IP Audio Interface Connection options This section illustrates how the IP Audio Interface can be used. A data stream can be sent and received by the IP Audio Interface. Different connection methods can be used depending on how the device is configured. 5.1 Unicast (point to point) Unicast means: a single data stream to a single predefined receiver device (Partner) in a LAN or WAN. A typical partner IP address: 192.168.100.50 1 Figure 5.1: Unicast example (1=LAN/WAN) 5.
IP Audio Interface 5.4 Connection options | en 15 Multicast Multicast means: predefined receiver devices (Partners) each receive a single data stream in a LAN or WAN. Typical partner IP addresses between: 224.0.0.1 to 239.255.255.255. 1 Figure 5.4: Multicasting example (1=LAN/WAN) 5.5 Re-broadcast Re-broadcast means: a local device receives a data stream from a remote device and resends it to other devices (Partners) in a LAN or WAN. 3 2 1 2 Figure 5.
en | Configuration 6 IP Audio Interface Configuration The IP Audio Interface uses dynamic HTML web pages for configuration and status information monitoring. Configuration parameters are stored in the IP Audio Interface via the web browser. Caution! ! 6.1 Your configuration parameters will be lost if the device is reset to factory default settings, see Front view, page 9. Connect to web browser Open a web browser on a PC that is connected to the same network as the IP Audio Interface. IP address.

Here you can set the parameters for the: Network (default page) – Streaming – Partner Table – Outgoing Route Table – Control Audio Settings Supervision Control I/O mapping – Control Input Mapping Table – Control Output Mapping Table Serial SNMP Security Default Settings Figure 6.
en | Configuration 6.2.1 IP Audio Interface Network Unit name Default: clear Enter a name for the device. This name will be displayed in the title of the web browser application page. IP address Default: 0.0.0.0 You can enter the 4 values of the announced IP address to create a static IP address, or ask your system administrator for a valid IP address and enter it here. Or you can enter e.g. 192.168.0.12 for an internal LAN. Subnet mask Default: 0.0.0.
IP Audio Interface 6.2.2 Configuration | en 19 Streaming Audio is transmitted using RTP over UDP. This requires no special configuration other than defining the UDP ports to be used for the communication. Figure 6.3: Steaming screen (default UDP settings) UDP Receiver Port Default: 3030 You can also select 0 if the port is disabled or enter a different number for receiving an RTP/UDP stream, between 0 (disabled) and 65535.
en | Configuration IP Audio Interface Submit / Cancel button Submit saves the set values, restarts the device and returns back to the last screen. Cancel restores the last submitted values. 6.2.3 Partner Table The Partner Table is used to set the route parameters of up to 16 remote IP Audio Interface devices (Partners). Figure 6.4: Partner Table screen (default) Ptnr (Partner) The first row, Un-known, is to configure the behavior of the receiving device for unknown partners, i.e.
Configuration | en IP Audio Interface 21 CI (Control Input) Enter the number of the Control Input (1 - 8) of the receiver that will accept the audio stream from this partner. If the transmitting partner is streaming (always) to this receiver, this selection determines the accepted audio stream unless it is overruled by a higher priority stream. The default 0 means that a stream from this partner is not selected by a Control Input.
en | Configuration 6.2.4 IP Audio Interface Outgoing Route Table The Outgoing Route Table is used to set the data stream for up to 16 remote IP Audio Interface devices (Partners). Figure 6.5: Outgoing Route Table screen (default) Configure the streaming depending on the following events: Stream Always Default: unchecked Check the check box to automatically stream to the selected partners (1..16) on start-up.
IP Audio Interface 6.2.5 Configuration | en 23 Control The Control menu is used to set the port on which the command data stream is received. Figure 6.6: Control screen (default) UDP command port Default: 12301 This sets the port through which the device will receive commands via UDP. To disable this port, set to 0. Web server port Default: 0 This sets the port through which the web server of the device can be reached. If set to 0, the default port 80 is used.
en | Configuration 6.2.6 IP Audio Interface Audio Settings The Audio Settings are used to set all available audio input and output parameters. Figure 6.7: Audio Settings screen example Audio inputs Default: In 2, Line For dual channel mode (MPEG encoding only), select input In 1 + In 2, Line. To use a microphone, select In 1, Microphone. If a microphone input is selected, you can set the microphone type to Dynamic or Condenser.
Configuration | en IP Audio Interface 25 Line gain Default: 0 dB You can adjust the gain of the line input (0...22.5 dB) to adapt it to the signal level of the source. Loop Input to Output Default: No You can select Yes to route the Audio Input signal immediately to the local Audio Output. This is typically done for testing. Acoustical feedback (howling) may occur if a microphone and a loudspeaker are connected. Pilot tone super.
en | Configuration IP Audio Interface The maximum delay that can be selected depends on the chosen audio coding format and whether the audio stream is full duplex or not. A more efficient coding scheme, lower sample rate and half duplex mode allows for a longer delay. For G.711 (u-Law or A-Law) at 8 kHz sampling rate and half-duplex, the delay can be set up to approximately 8 s. Audio format – Encoding Default: MPEG1-L2/22.05 kHz You can select the audio encoding format here.
IP Audio Interface 6.2.7 Configuration | en 27 Supervision The IP Audio Interface contains detectors for supervision of various functions of the device. This way internal or external failures, disconnections or short circuits can be detected. Faults are reported via the Fault Relay and can be passed to partner devices. Figure 6.8: Supervision screen (default) Max. Internal temperature Default: 80 °C Enter the threshold for the Maximum Internal Temperature.
en | Configuration IP Audio Interface Supervision Sensor Mapping Default: None In the Supervision Sensor Mapping table you can select what actions should be taken if one of the faults occur that are in the table.
