Selecting the Frame Trigger Wait Signal as the Source Signal for

the Output Line

The frame trigger wait signal can be selected to act as the source signal for e.g. camera output

line 1. Selecting a source signal for the output line is a two step process:

 Use the Line Selector to select output line 1.

 Set the value of the Line Source Parameter to the frame trigger wait signal.

You can set the Line Selector and the Line Source parameter value from within your application

software by using the Basler pylon API. The following code snippet illustrates using the API to set

the selector and the parameter value:

Camera.LineSelector.SetValue( LineSelector_Out1 );

Camera.LineSource.SetValue( LineSource_FrameTriggerWait );

You can also use the Basler pylon Viewer application to easily set the parameters.

For more information about selecting the source signal for an output line on the camera, see

Section 7.6.2.5 on page 68.

For more information about the electrical characteristics of the camera’s output lines, see

Section 7.6.2.1 on page 64.

For more information about event reporting, see Section 10.4 on page 171.

For more information about hardware triggering, see Section 8.2 on page 78.

8.3.3.3 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 signall will go high whenever the camera enters a "waiting for line start trigger"

status. The signal will go low when an external 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 and a line start overtrigger event

will be reported.

The line trigger wait signal can be selected as the source signal for one of the output lines on the

camera.

For more information about selecting the source signal for an output line on the camera, see

Section 7.6.2.5 on page 68.

For more information about the electrical characteristics of the camera’s output lines, see

Section 7.6.2.1 on page 64.
