Image Acquisition ControlBasler scout 897.4.4 Using A Software Acquisition Start Trigger(Standard Mode)7.4.4.1 IntroductionIf the camera’s Acquisition Start Trigger Mode parameter is set to on and the Acquisition StartTrigger Source parameter is set to software, you must apply a software acquisition start triggersignal to the camera before you can begin frame acquisition.A software acquisition start trigger signal is applied by: Setting the Trigger Selector parameter to Acquisition Start. Executing a Trigger Software command.The camera will initially be in a "waiting for acquisition start trigger" acquisition status. It cannot reactto frame trigger signals when in this acquisition status. When a software acquisition start triggersignal is received by the camera, it will exit the "waiting for acquisition start trigger" acquisition statusand will enter the "waiting for frame start trigger" acquisition status. It can then react to frame starttrigger signals. When the number of frame start trigger signals received by the camera is equal tothe current Acquisition Frame Count parameter setting, the camera will return to the "waiting foracquisition start trigger" acquisition status. When a new software acquisition start trigger signal isapplied to the camera, it will again exit from the "waiting for acquisition start trigger" acquisitionstatus and enter the "waiting for frame start trigger" acquisition status.(Note that as long as the Trigger Selector parameter is set to Acquisition Start, a softwareacquisition start trigger will be applied to the camera each time a Trigger Software command isexecuted.)7.4.4.2 Setting the Parameters Related to Software Acquisition StartTriggering and Applying a Software Trigger SignalYou can set all of the parameters needed to perform software acquisition start triggering from withinyour application software by using the Basler pylon API. The following code snippet illustrates usingthe API to set the parameter values and to execute the commands related to software acquisitionstart triggering with the camera set for continuous frame acquisition mode:// Set the acquisition mode to continuous(the acquisition mode must// be set to continuous when acquisition start triggering is on)Camera.AcquisitionMode.SetValue( AcquisitionMode_Continuous );// Select the acquisition start triggerCamera.TriggerSelector.SetValue( TriggerSelector_AcquisitionStart );// Set the mode for the selected triggerCamera.TriggerMode.SetValue( TriggerMode_On );// Set the source for the selected triggerCamera.TriggerSource.SetValue ( TriggerSource_Software );// Set the acquisition frame count
