10-2-5-4 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 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).

10-2-5-5 External trigger delay function
In most cases when a delay is needed 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).
