Selecting the Frame Trigger Wait Signal as the Source Signal for an Output Line
The frame trigger wait signal can be selected to act as the source signal for a camera output line,
e.g. Line 2. Selecting a source signal for an output line is a two step process:
Use the Line Selector to select the output line, e.g. Line 2.

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_Line2);
camera.LineSource.SetValue(LineSource_FrameTriggerWait);
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on
For more information about changing the selection of an output signal as the source signal for the
output line, see Section 5.12.1 on
For more information about the electrical characteristics of camera output lines, see Section 5.8.1
