With DP74, still images can be acquired and commercially-available shutters can be controlled by external trigger
signals.
Trigger input
When the trigger signal is inputted from external equipments, the still image can be acquired using cellSens / OLYMPUS
Stream.
When the trigger signal is detected at the edge, the image is acquired with the pre-set exposure time. The positive and
negative logics of signals can be switched with cellSens / OLYMPUS Stream.
The exposure starts within 100 μs after the trigger input.
The trigger input signal is TTL compatible.
