Image Acquisition ControlBasler scout 1017.5.3.3 Frame Start Trigger DelayThe trigger delay feature lets you specify a delay (in microseconds) that will be applied between thereceipt of a hardware frame start trigger and when the trigger will become effective.For more information about the trigger delay feature and how to use it, see Section 9.14 onpage 231.7.5.3.4 Setting the Parameters Related to Hardware Frame Start Trig-gering and Applying a Hardware Trigger SignalYou can set all of the parameters needed to perform hardware frame start triggering from within yourapplication by using the Basler pylon API. The following code snippet illustrates using the API to setthe camera for single frame acquisition mode with the trigger mode for the acquisition start triggerset to off. We will use the timed exposure mode with input line 1 as the trigger source and with risingedge triggering. In this example, we will use a trigger delay:// Set the acquisition mode to single frameCamera.AcquisitionMode.SetValue( AcquisitionMode_SingleFrame );// Select the acquisition start triggerCamera.TriggerSelector.SetValue( TriggerSelector_AcquisitionStart );// Set the mode for the selected triggerCamera.TriggerMode.SetValue( TriggerMode_Off );// Select the frame start triggerCamera.TriggerSelector.SetValue( TriggerSelector_FrameStart );// Set the mode for the selected triggerCamera.TriggerMode.SetValue( TriggerMode_On );// Set the source for the selected triggerCamera.TriggerSource.SetValue ( TriggerSource_Line1 );// Set the trigger activation mode to rising edgeCamera.TriggerActivation.SetValue( TriggerActivation_RisingEdge );// Set the trigger delay for one millisecond (1000us == 1ms == 0.001s)double TriggerDelay_us = 1000.0;Camera.TriggerDelayAbs.SetValue( TriggerDelay_us );// Set for the timed exposure modeCamera.ExposureMode.SetValue( ExposureMode_Timed );// Set the exposure timeCamera.ExposureTimeAbs.SetValue( 3000 );// Execute an acquisition start command to prepare for frame acquisitionThe trigger delay will not operate if the Trigger Mode parameter for frame start isset to off or if you are using a software frame start trigger.
