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.

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).
