Image Acquisition Control AW0009760300094 Basler aviator GigESelecting the Acquisition Trigger Wait Signal as the Source Signalfor the Output LineThe acquisition trigger wait signal can be selected to act as the source signal for camera outputline 1, line 2, line 3, or line 4. Selecting a source signal for an output line is a two step process: Use the Line Selector to select output line 1, line 2, line 3, or line 4. Set the value of the Line Source Parameter to the acquisition trigger wait signal.You can set the Line Selector and the Line Source parameter value from within your applicationsoftware by using the Basler pylon API. The following code snippet illustrates using the API to setthe selector and the parameter value:Camera.LineSelector.SetValue( LineSelector_Out1 );Camera.LineSource.SetValue( LineSource_AcquisitionTriggerWait );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 on page 21.7.7.3.2 Frame Trigger Wait SignalOverviewAs you are acquiring frames, the camera automatically monitors the frame start trigger status andsupplies a signal that indicates the current status. The Frame Trigger Wait signal will go highwhenever the camera enters a "waiting for frame start trigger" status. The signal will go low whenan external frame start trigger (ExFSTrig) signal is applied to the camera and the camera exits the"waiting for frame start trigger status". The signal will go high again when the camera again entersa "waiting for frame trigger" status and it is safe to apply the next frame start trigger signal.If you base your use of the ExFSTrig signal on the state of the frame trigger wait signal, you canavoid "frame start overtriggering", i.e., applying a frame start trigger signal to the camera when it isnot in a "waiting for frame start trigger" acquisition status. If you do apply a frame start trigger signalto the camera when it is not ready to receive the signal, it will be ignored and a frame startovertrigger event will be reported.
