Figure 2-4 Talkback Configuration
Step 3: Test the Talkback
When you listen on the headset and nobody is talking, you’ll hear a tone each ten seconds
to show that the audio circuit is operating.
Note: This is open talkback. Everyone on the network can hear you at all times. A Push
to Talk switch can be installed with the microphone to stop this.
Step 4: Explore the Remote Setting
You’ll see that in Configuration Audio Mode there is a setting called Remote. If you
are using headsets on each NETNode they will continue to operate as described above.
Internal mode only distributes the talkback audio within the local mesh network.
But, Remote mode allows the onward distribution of this audio on an external IP network
with RTSP protocols.
This enables you to connect a PC to a second NETNode and hear what is being said across
the network with streaming software like VLC and the URL:
rtsp://ip_address_of_unit/audio.sdp
