Frame Start Trigger Delay; Setting The Parameters Related To Hardware Frame; Start Triggering - Basler GIGE VISION ace acA640-100gm/gc Manual

6.4.3.3
The frame start trigger delay feature lets you specify a delay (in microseconds) that will be applied
between the receipt of a hardware frame start trigger and when the trigger will become effective.
The frame start trigger delay can be specified in the range from 0 to 10000000 µs (equivalent to
10 s). When the delay is set to 0 µs, no delay will be applied.
To set the frame start trigger delay:
Set the camera's Trigger Selector parameter to frame start.
Set the value of the Trigger Delay Abs parameter.
6.4.3.4
You can set the all of parameters needed to perform hardware frame start triggering from within your
application by using the pylon API.The following code snippet illustrates using the API to set the
parameter values and execute the commands related to hardware frame start triggering with the
camera set for single frame acquisition mode and the acquisition start trigger mode set to off. In this
example, we will use the timed exposure mode with rising edge triggering and we will use a trigger
delay:
// Set the acquisition mode to single frame
Camera.AcquisitionMode.SetValue( AcquisitionMode_SingleFrame );
// Select the acquisition start trigger
Camera.TriggerSelector.SetValue( TriggerSelector_AcquisitionStart );
// Set the mode for the selected trigger
Camera.TriggerMode.SetValue( TriggerMode_Off );
// Select the frame start trigger
Camera.TriggerSelector.SetValue( TriggerSelector_FrameStart );
// Set the mode for the selected trigger
Camera.TriggerMode.SetValue( TriggerMode_On );
// Set the source for the selected trigger
Camera.TriggerSource.SetValue ( TriggerSource_Line1 );
// Set the trigger activation mode to rising edge
Camera.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 );
