Start trigger mode
The start trigger mode is 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. For example, when it is necessary to measure the
phenomenon after stimulation, it is possible to start continuous image acquisition at the
stimulation timing.
The start trigger mode is 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 free running mode. In the start
trigger mode, the camera starts exposure and switches to free running mode by the edge of an
external trigger signal (rising / falling edge).

External trigger delay function
In most cases when a delay between the laser pulse emission and the exposure start is needed,
a delay unit is set between the laser and camera to control trigger timing. In each external trigger
mode of the camera, the delay can be set to the trigger signal input to the camera by command.
With this setting, a range of trigger can be arranged without a delay unit. The range for delay
time is 0 µs to 10 s (10 µs steps).
