Trigger delay
The camera can delay the trigger signal.
When a trigger signal is input before the trigger delay time, or a trigger which contains noise is recognized, the image
cannot be displayed. This is not a malfunction.
Trigger counter
Accepted triggers by which video output is performed are counted. Triggers are counted up by the internal counter even
in the free-run operation. Setting 0 resets the counter. Video output is not performed for triggers that coincide with the
double exposure timing, but triggers are counted up. Triggers that have been removed by trigger range limit are not
counted. The trigger counter returns to 0 when the upper limit (2147483647) is reached.
Frame counter
The frame counter increases when an image is output. Setting 0 resets the counter. Frames whose image cannot be
output due to triggers that coincide with the double exposure timing are not counted. The trigger counter returns to 0
when the upper limit (2147483647) is reached.
Trigger range limit
Only signals in the set trigger width can be accepted as the trigger signal. This functions as a noise filter, which removes
chattering or disturbance noise in the trigger signal line. This also functions as a trigger selector, whereby only a specific
camera can be operated by the trigger when multiple cameras share one trigger signal line. When the trigger signal is
input, exposure is started immediately to increment the trigger counter; however, when trigger width is out of the range,
video is not output and the trigger counter is decremented. If the shutter time is set shorter than the upper limit, triggers
will be received and video is output even if the trigger signal is wider than the trigger range limit. If the trigger source
is soft trigger, trigger range is not enabled.
