12-1307A01 without PTT; 12-1307A01 with PTT) can be purchased
from us. Handsets must have carbon microphone elements
installed. Dynamic microphones do not work with the module. Handsets
with a push-to-talk (PTT) button are supported and recommended, as
background noise can activate the VOX circuit and interrupt the payload
data.
Operation
To operate the orderwire, activate the handset (PTT or VOX). This keys
the transmitter and passes the audio over the network to the handset of
the Master Station. Only one person can speak at a time (simplex). In
noisy locations, it might be necessary to cover the handset mouthpiece
to prevent accidental keying of the transmitter.
NOTE:
When the transmitter is keyed by the orderwire operation,
normal payload data is interrupted.
Be sure to disconnect the module or handset to restore normal
data communications.
