9-5-3-3 Current synchronous readout trigger mode
In the current synchronous readout trigger mode it is possible to control the exposure start timing
by using ACT command from application software. First, the camera is set to be idle condition by
ACT S command input. In idle condition, the camera does not start exposure even by a trigger
signal in yet. Then, the camera start an exposure by ACT I command and then start to readout by
input external trigger.
(In the normal synchronous readout trigger mode, the camera does not readout by the first
trigger pulse after ACT I command.)

START TRIGGER MODE

The start trigger mode is used to start operating the camera by a trigger input for a
continuous imaging. It is useful to secure the frame rate as fast as possible when continuous
image acquisition and not to sacrifice the exposure time. Example, when it is necessary to
measure the phenomenon after stimulation, it is possible to start continuous image
acquisition at the stimulation timing.
9-5-4-1 Normal start trigger mode
The start trigger mode is used to start operating the camera by a trigger input for continuous
imaging, and it works at the highest frame rate because it is operated in internal trigger
mode. In the start trigger mode, the camera starts exposure and switches to internal trigger
mode by the edge of an external trigger signal (rising / falling edge).
