Guideline for Overlapped Acquisition
If you are operating the camera in such a way that frame acquisitions will be overlapped, there is
an important guideline you must keep in mind:
You must wait a minimum of 400 µs after the end of exposure for line one in frame N before
you can trigger acquisition of frame N+1.
This requirement is illustrated in Figure 72
If this guideline is violated, the camera will ignore the frame start trigger signal and will declare a
Frame Start Overtrigger event.
You can avoid violating this guideline by using the camera’s Frame Trigger Wait signal to
determine when exposure can safely begin.
Overlapped frame acquisition
 can only be performed when the camera is in the electronic rolling shutter
mode (ERS).
 can not be performed when the camera is set for global reset release rolling
shutter mode.
