This output signal indicates reception of a defined audio band (inband) tone.
This signal might be used to alert an application device to the presence of a
pilot tone prior to other traffic being received.
1. Set up the radio to operate with inband tone signalling on the
intended operating channel.
2. Configure the inband tone parameters: tone frequency, minimum
duration, and tone hold time
3. Configure an output line and associate it with this action. Set the
active state to be high or low (as required).
The output signal response time is dominated by the settings of minimum
tone duration and tone hold time.
Note
The detection response time may lengthen if the S/N of the
incoming signal is poor.
This output signal is activated once the presence of the pre-defined in-band
tone has been detected for the configured minimum duration.
The signal will remain active until the tone has not been detected for the
duration of the configured tone hold time.
None.
This output signal is used to indicate whether the radio has been stunned by
receiving a Selcall that contained a control status set to full stun or Tx stun.
This can be used to indicate to external applications, that the radio is
unusable, or to control an external device to disable other equipment.
Configure an output line and associate it with this action. Set the active state
to be high or low (as required).
The response time of all output lines is less than 2ms after the last tone in
the sequence was received.
When the radio becomes stunned, this output line becomes active.
When the radio is revived, this output line becomes inactive.
None.
