Task Manager Inputs and Actions 213
When the flag is enabled, CWID is transmitted as configured in the channel
profile’s CWID System tab.
If the channel profile does not provide for CWID, this flag has no effect.
Transmit CWID now
The ‘do now’ action
Transmit CWID now
instructs the base station to
immediately transmit the CWID message defined in the CWID System tab.
This action enables you to configure CWID transmissions in a way that is not
otherwise possible. For example, you could have the CWID transmitted more
than once a minute or at every transmit tail.
Transmit CWID now
works even if a CWID action has disabled the CWID
system flag.
Transmitter power override actions
Task Manager can override the normal transmit power level and instruct the PA
to use a special power level. This action can be used to reduce the transmit
power if the DC input level is low or to increase the transmit power when the
received signal strength is low. If the base station is transmitting when the
transmit power is changed, there will be a short interruption to the transmission.
The system flag Transmit power override indicates the current status. If it is
enabled, Task Manager has overridden the configured transmit power level.
The special power level is set by the Task Manager override box (in the channel
profile, General tab).
When the base station enters Run mode, Task Manager clears any transmit
power override. The normal transmit power level is used.
When Task Manager enables the transmit power override, the PA uses the Task
Manager override transmit power level.
When Task Manager disables the transmit power override, the PA reverts to
using the normal transmit power level, as defined by the current channel profile
or the channel table.
Example
IF Battery voltage low THEN Enable transmitter power override
IF NOT
Battery voltage low
THEN
Disable transmitter power override
Signalling Profile Actions
Signalling profile actions relate to configuration items that are defined in
signalling profiles. You can put tasks with a signalling profile action 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. If the task is in the General folder, it is always processed.
Subaudible Decoding
Subaudible decoding override actions can enable, disable, or toggle the
Subaudible decode system flag. This gives you an extra layer of control over the
base station’s response to subaudible signalling.
When the base station enters Run mode, the flag is enabled.
When the flag is enabled, any subtones are decoded and checked against the
current signalling profile. A received signal is only valid if it contains a specified
subtone.
