AW00118302000 Acquisition Control

Basler racer GigE 79

Setting the Acquisition Mode and Issuing Start/Stop Commands

You can set the Acquisition Mode parameter value and you can issue Acquisition Start or

Acquisition Stop commands from within your application software by using the pylon API. The code

snippet below illustrates using the API to set the Acquisition Mode parameter value and to issue an

Acquisition Start command. Note that the snippet also illustrates setting several parameters

regarding frame and line triggering. These parameters are discussed later in this chapter.

Camera.AcquisitionMode.SetValue( AcquisitionMode_SingleFrame );

Camera.TriggerSelector.SetValue( TriggerSelector_FrameStart );

Camera.TriggerMode.SetValue( TriggerMode_On );

Camera.TriggerActivation.SetValue( TriggerActivation_RisingEdge );

Camera.TriggerSelector.SetValue( TriggerSelector_LineStart );

Camera.TriggerMode.SetValue( TriggerMode_On );

Camera.TriggerActivation.SetValue( TriggerActivation_RisingEdge );

Camera.ExposureMode.SetValue( ExposureMode_Timed );

Camera.ExposureTimeAbs.SetValue( 55 );

Camera.AcquisitionStart.Execute( );

For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide

and API Reference.

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

For more information about the pylon Viewer, see Section 3.1 on page 23.

When the camera's acquisition mode is set to single frame, the maximum possible

acquisition frame rate for a given AOI cannot be achieved. This is true because

the camera performs a complete internal setup cycle for each single frame.
