200 Part I: Task Manager
© Tait Electronics Limited December 2007
Rx Gate line active
The
Rx Gate line active
input becomes true when the Rx Gate line on the
system interface goes low. This input is similar to
Receiving valid signal
,
however the Rx Gate line becomes active not just when the base station is
receiving a valid signal, but whenever
there is a valid line audio output. This
audio output can also come from the base station microphone or from line
input (when loopback is enabled and the Tx Key line is active).
Note:
If the current channel profile does not specify an audio path
to line out, the Rx Gate line does not become active when a valid
signal is being received.
Talk through repeater enabled
The override input
Talk through repeater enabled
becomes true when
Task Manager turns the Talk through repeater system flag on. 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.
Example
You could use this input as part of a set of tasks that impose a time limit on calls
when in repeater mode.
IF Talk through repeater enabled
AND
PA keyed by valid Rx
THEN
Start timer (CallTimeLimit)
The two inputs need to be combined into a custom input. When it become
true, a timer is started. When this timer expires, other tasks can disable the
repeater, start a timer for the transmit lockout, and re-enable the repeater.
Transmitter enabled
The override input
Transmitter enabled
becomes true when Task Manager
turns the Transmitter system flag on. 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.
Tx Key input enabled
The override input
Tx Key input enabled
becomes true when Task
Manager turns the Tx Key system flag on. 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.
Signalling Profile Inputs
Signalling profile inputs relate to configuration items that are defined in
signalling profiles. You can put tasks with a signalling profile input into the
folder for a particular signalling profile or into the General folder. If the task is
in a signalling profile folder, it is only processed when the current channel uses
that profile. It the task is in the General folder, it is always processed.
Subtone decoding enabled
The override input
Subtone decoding enabled
becomes true when Task
Manager turns on the Subaudible decode 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.
