Audio
If audio is supported, two 3.5 mm jacks are installed on the
units. Appendix G, page 79, presents the jack pinouts for
input and output.
Data Transmission
Two transmission modes for audio data are available:
‹
Full duplex—Data is transferred in both directions
simultaneously.
‹
PTT/PTL—The push-to-talk/push-to-listen mode allows
you to control audio communication between two units.
When creating a point-to-point connection between a
receiver and a transmitter in SConfigurator, you set the
transmission mode in the Connection Creator window.
The PTT/PTL transmission mode requires specific hardware
configuration:
‹
To activate the audio reception circuit (for PTL) on
receiver units, you have to short the input 1 and ground
terminals on the multipole connector. You cannot
activate PTL on transmitters.
‹
To activate the audio transmission channel (for PTT),
you must trigger an activation switch (for example, a
button) that is based on the shorting of the input 2 and
ground terminals.
If both the transmitter’s and receiver’s PTT switches are
activated at the same time, the receiver will have
precedence: Audio will be transferred from the receiver to
the transmitter. If the receiver’s PTL and PTT functions are
activated at the same time, PTT will be activated and PTL
will be ignored.
Note
The input 1 terminal is also used for alarms. It will perform both
functions if you set up the PTL mode.
