Image Acquisition Control132 Basler scoutYou 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_ExposureActive );You can also use the Basler pylon Viewer application to easily set the parameters.For more information about changing the assignment of camera output signals to physical outputlines, see Section 6.2.1 on page 67.For more information about the electrical characteristics of the camera’s output lines, seeSection 5.7.2 on page 60.7.11.2 Acquisition Status IndicatorWhen controlling image acquisition with a software trigger you can use the acquisition status featureto determine when the camera is rady to be triggered for an image acquisition.For more information about the acquisition status feature, see Section 9.15 on page 233.7.11.3 Trigger Ready Signal (All Models Except scA750-60)As described in the previous section, the cameras can operate in an “overlapped” acquisitionfashion. When the camera is operated in this manner, it is especially important that: the exposure time of a new image acquisition not start until exposure of the previouslyacquired image is complete, and the exposure time of a new image acquisition not end until readout of the previously acquiredimage is complete.The camera supplies a “Trigger Ready” (TrigRdy) output signal you can use to ensure that theseconditions are met when you are using a hardware trigger signal to trigger image acquisition. Thetrigger ready signal relates to different trigger signals, depending on the image acquisition controlmode: In standard mode, the trigger ready signal relates to the frame start trigger signal In legacy mode, the trigger ready signal relates to the acquisition start trigger signal.The information in this section applies to all camera models except thescA750-60 fm/fc. For information about scA750-60 fm/fc cameras, seeSection 7.11.4 on page 135.
