Task Manager Inputs and Actions 201
Subtone encoding enabled
The override input
Subtone encoding enabled
becomes true when Task
Manager turns on the Subaudible encode system flag. This occurs on entering
Run mode. It also occurs if a Task Manager task turns the flag on after a
previous task has disabled it.
Tone nn detected
This input becomes true when the receiver detects a subaudible tone that is
defined in the current signalling profile (Subaudible Signalling tab).
nn refers to
the number of the tone specified in that profile (a profile can have up to 16
tones defined).
Example
Enable the technician to request the emailing of a status message
IF Tone 2 detected THEN Email status now
When the base station receives the subaudible tone, the base station emails a
status message. The signalling profile is set up so that this tone only results in
Task Manager action. To obtain status information, the technician transmits
that subaudible tone: Task Manager then instructs the base station to email the
status message to the configured destination.
System I/O
System I/O inputs involve digital and audio inputs and outputs over the base
station’s system interface board.
Balanced input low
The
Balanced input low
input becomes tru e when the audio level on the
unbalanced line in falls below the minimum level specified in Configure >
Alarms > Thresholds.
This input is useful in applications where the base station can expect a signal all
the time. It lets you define tasks that specify actions when the expected audio
input ceases.
Example
IF Balanced input low
THEN
Start over the air alarm
If the line fails, the base station sends alarm pips over the air.
Digital input active
The
Digital input active
input becomes true when the digital input becomes
active.
Digital output nn active
The
Digital output nn active
input becomes true when the base station sets
the digital output.
RSSI high
The
RSSI high
input becomes true when the RF signal that the base station is
receiving exceeds the maximum signal strength specified in Configure > Alarms
> Thresholds.
