TM Tx Key actions
TM Tx Key actions can key or unkey the transmitter. The effect is exactly the
same as if the Tx Key line were activated or de-activated. The effect takes
place through the TM Tx Key system flag.
When the base station enters Run mode, the flag is disabled.
When the flag is enabled,
the PA transmits and the balanced and/or
unbalanced line input is used for modulation.
When the flag is disabled after being enabled, Task Manager stops keying the
transmitter. However, if the Tx Key line is active, the PA continues to transmit;
the flag does not override the Tx Key line signal.
Set flag
Task Manager can set or clear any of 16 numbered flags. A flag can only have
one of two states: set or cleared. The state of a flag can be used as an input in
other tasks.
Clear flag
Task Manager can set or clear any of 16 numbered flags. A flag can only have
one of two states: set or cleared. The state of a flag can be used as an input in
other tasks.
Increment counter
The Increment counter action adds one to the counter specified. When a
counter reaches its specified maximum, it triggers actions with the input
Counter at maximum.
Reset counter
The Reset counter action sets the value of the counter specified to zero, so that
it must begin counting anew.
Decrement counter
The Decrement counter action subtracts one from the current value of the
counter specified.
Select channel profile (Profilename)
The select channel profile action instructs the base station to operate on the
specified channel profile. If Task Manager selection of the channel profile is not
enabled (see “TM channel profile selection” on page 209), this action has no
effect.
