AW00118508000 Acquisition Control
Basler racer Camera Link 82
Read the value of the Status Line Trigger Wait register.
If the value is set to 0, the camera is not waiting for the trigger signal.
If the value is set to 1, the camera is waiting for the trigger signal.

6.3.3 Line Trigger Wait Signal
As you are acquiring lines, the camera automatically monitors the line start trigger status and
supplies a signal that indicates the current status.
The Line Trigger Wait signal will go high whenever the camera enters a "waiting for line start trigger"
status. The signal will go low when an hardware line start trigger (ExLSTrig) signal is applied to the
camera and the camera exits the "waiting for line start trigger status". The signal will go high again
when the camera again enters a "waiting for line trigger" status and it is safe to apply the next line
start trigger signal.
If you base your use of the ExLSTrig signal on the state of the line trigger wait signal, you can avoid
"line start overtriggering", i.e., applying a line start trigger signal to the camera when it is not in a
"waiting for line start trigger" acquisition status. If you do apply a line start trigger signal to the
camera when it is not ready to receive the signal, it will be ignored.
The line trigger wait signal can be selected as the source signal for the CL spare bit on the camera.
For more information about selecting the source signal for the CL spare bit on the camera, see
Section 5.5.2 on page 47.
Fig. 29 and Fig. 30 illustrate the Line Trigger Wait signal with exposure and readout overlapped.
The figures assume raising edge triggering.
