Frame Trigger Wait Signal Details (All Models Except acA1920-25um/uc,
acA2500-14um/uc, acA3800-14um/uc, acA4600-10uc)
When the camera is set for the timed exposure mode, the rise of the Frame Trigger Wait signal is
based on the current Exposure Time parameter setting and on when readout of the current frame
will end. This functionality is illustrated in Figure 65.
If you are operating the camera in the timed exposure mode, you can avoid overtriggering by always
making sure that the Frame Trigger Wait signal is high before you trigger the start of frame capture.
