Trigger Edges and Width
When the camera is in Trigger Edge mode, it starts
shooting by detecting the rising or falling edge of a
trigger signal and performs shooting for the exposure
time specified in advance.
In Trigger Width mode, shooting is performed by
detecting the effective period of the trigger signal as the
exposure time.

Special Trigger Modes
In a normal trigger operation, the settings, such as
exposure time, gain and imaging region, must be
changed in advance for each trigger input when shooting
under different conditions. Such setting changes can be
eliminated by activating a special trigger mode which
makes shooting under different conditions easier. Up to
16 configurations of camera settings can be used. There
are two types of special trigger modes: Bulk mode, in
which shooting continues after being started by a trigger
signal, and Sequential mode, in which shooting is
performed each time a trigger signal is detected. The
next exposure will start after the current image output is
completed. Therefore, the second and subsequent
trigger signal inputs in Sequential mode must be more
than 3 msec. after the end of the preceding image output.
Bulk mode
