3.4.1.3. Timing Chart for Shuttered Operation in START and RANDOM Trigger Modes with
“Reset” in Effect
The below chart shows the temporal relationship between timing signals when shuttering function
is added to START and RANDOM trigger mode with Reset is in effect.
Note: A shorter exposure period is set by the shuttering function, in addition to the Expose pos
signal being reset at the incoming trigger.
Note: START trigger mode starts recording when a trigger is received and continues recording
images until the memory is full. RANDOM mode records a preset number of frames at each trigger
and records until the memory is full.
Note: The amount of delay between the incoming and internal triggers greatly depends on the type
of incoming triggers.
