To store changed settings click on "Apply" at the bottom of the page.
The device will restart with the new setting.
Input Source
Choose the desired input source.
Default setting is "Mic".
Encoding
Choose between different encoding types and sampling frequencies ("uLaw", "aLaw" or "PCM" at 8 or 24 kHz).
Default setting is "uLaw 24 kHz".
Volume
Choose between "0"% and "100"% in 5% steps.
Default: "50"%
Microphone Gain
Microphone gain dB, increase if your microphone is too faint, decrease if it's too loud or overdriven. Default: "21dB"
A/D Amplifier Gain
A/D converter preamplification in dB. Increase if the audio signal too faint, decrease if it's too loud or overdriven. Default: "0dB"
RTP mode
If set, audio will be transmitted over RTP (used in VoIP systems), if not set raw UDP will be used as the transport protocol which is the default.
In RTP mode packet size is given by the encoding used and can not be altered by the user (the packet size setting below is ignored).
Default setting is "OFF".
Streaming mode
"send always" will stream always
"send on level" will stream if the input audio level goes above the configured "Input Trigger Level"
"send on I0/DI1" will stream if the I0 (Annuncicom100/Legacy) or DI1(Annuncicom1000/Exstreamer1000) is activated
"respond" will stream back as long as a stream is beeing received
Default setting is "send always".
Input Trigger Level
Triggering input audio level if "send on level" mode is selected. Accepted range: 0-32767
Default: "1000"
Inactivity Timeout
"Send on level" streaming stops after this number of milliseconds of no input audio signal.
Default: "1000ms"
Destination IP
Destination address where the audio stream will be sent to. Enter your peer's address here.
Destination Port
UDP port to which the audio stream will be sent to. Enter the UDP receiving port number of your peer.
Default port: "3030"
Source IP
Enter IP address of your source here. The annuncicom will receive audio stream only from this address.
This address can be 0.0.0.0 to accept any stream coming to the receiving port; a multicast address to subscribe to a specific multicast group; or a unicast address to receive stream from a specific source only. Default: "0.0.0.0"
Local Rx Port
Local UDP stream receive port.
Set to a value between 0 (disabled) and 65535.
Default port is "3030".
Keepalives
Send periodic keepalive messages if the communication partner is not sending any audio.
Turn this feature on if you're behind a FW/NAT and you want to keep the communication port open.
Default is "OFF".
Delay
The RTP decoder keeps constant decoding latency within one frame accuracy. Set the required delay in milliseconds.
The delay value should be set large enough to cope with network jitter (difference in packets delivery time) and possible packet loss. Increase the value if you are experiencing audio dropout.
The lowest recommended setting is about 80ms for uLaw/ALaw 8kHz.
Default setting is "100 milliseconds".
Frame Duration
Together with the Delay the Frame Duration setting can help to reduce the overall delay of the point-to-point link. The Frame Duration defines how long chunk of audio is transmitted in one packet. The standard frame duration is 20 milliseconds.
Please note that low duration increases the network bandwidth usage and system utilisation.
Default setting is "20 milliseconds".
Relay Off Delay
Using this variable, the output relay activation can be prolonged, which can be useful when the relay is being used to control, for example, an amplifier. The relay off delay is needed when using MP3 encoding, where the unpredictable nature of the compression means that it is not possible to predict how long the audio will take to reach and transmit at the remote end. Default value is: "1200 msec." Set 0 set disable it.
Serial Gateway
Select communication protocol "UDP" or "TCP" to enable gateway functionality. Further parameters are shown based on the selected mode.
Default protocol is "UDP".
"Destination IP (TCP mode)" Defines IP address of remote device to establish TCP connection.
"Destination port (TCP mode)" Defines the port number of remote device to establish a TCP connection.
"Connection Type (TCP mode)" "Active" initiate connection with remote device. "Passive" Listen for incoming connection.
"Local port (TCP Mode)" Defines the local port to listen on for an incoming TCP connection.
"Communication port (UDP Mode)" Defines the port on the audio partner to use for serial gateway. IP address is defined as above in Streaming "Destination IP".
