Values description
•ExposureStart: Chunk data is captured when an exposure starts.
•ExposureTrigger: Chunk data is captured when the camera receives a valid trigger.
•ReadOutStart: Chunk data is captured when the readout of the sensor starts.
Code example
C++
// Determine the current entry of ChunkLatchTriggerSource

// Get a list of all available entries of ChunkLatchTriggerSource

&& (entry->AccessStatus()!=peak::core::nodes::NodeAccessStatus::NotImplemented))
{

}
}
// Set ChunkLatchTriggerSource to "ExposureStart"
nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("ChunkLatchTriggerSource")->SetCurrentEntry("ExposureStart");
