9.1.1 Station 1 configuration
Wiring
Station 1 is connected to an intercom panel:
Speaker to speaker out (C).
Microphone to Microphone In (E or F).
The TALK button to Input 0 (B1 and B3).
Network settings
If you have a DHCP Server in your network the device will
automatically get an IP address and no changes are needed.
Skip this step and go to Audio settings.
Use the following settings if you prefer to have a Static IP
or if no DHCP server is available.
SonicIP is disabled; no need to hear it on power up as the
IP Address is static and known and the device will stay
powered most of the time.
Audio settings
Change the Input source to "Mic".
The Microphone Gain as well as the Volume might need
adjustment later on depending on the microphone and
speaker used.
Quality and Sampling frequency settings can be decreased
to lower the network traffic but this will increase the
playback delay.
Streaming settings
No changes needed.
Streaming mode is set to talk when the TALK command is
activated (i.e. TALK button pressed).
Post Trigger Play is set to talk on for 1 second after the
button has been released. This prevents cut offs.
When receiving a stream, 4096 Bytes will be buffered first
before playing it back over the speaker. Lower this value to
minimize delay, increase this value to prevent dropouts.
The stream will be transmitted using a UDP broadcast on
port 3030.
