2.3 Working with Talkback
When you have established a mesh network it is possible to attach headsets to NETNodes in
the network. These headsets let you to listen and talk to a different operator on the network
(‘party line’).
Step 1: Rig the Headsets
It will be necessary to have at least two fully configured NETNodes, at least two headsets
and the correct Microphone/Headphone External Cable Assembly
 NETNode-3-Robust – CA0589
 NETNode-3-Plain – CA0588
 NETNode-Mini Plain – CA0588
Here’s an example using the NETNode-3-R (Robust):
1. With the Microphone/headphone cable, connect to the Audio receptacle on the NETNode
marked T/B (NETNode-3-Plain & NETNode-3-Mini Plain) or CTRL/DATA (NETNode-3-
Robust).
2. Connect the microphone plug of the headset to the inline plug marked IN on the CA0589
cable.
3. Connect the headphone plug of the headset to the inline plug marked OUT on the
CA0589 Cable.
4. Do the same for other NETNodes with headsets.
