} When the cellSens / OLYMPUS Stream software is used, the DP73 can record still images or control a commercially
available shutter based on an external trigger signal.
Trigger Input
· The trigger input from external equipment can be used to start still image acquisition using the cellSens / OLYM-
PUS Stream.
· The trigger input is detected at the edge and the cellSens / OLYMPUS Stream starts to acquire the images based
on the preset exposure time. The positive and negative logics can be switched with the cellSens / OLYMPUS
Stream.
· The exposure is started within 100 μsec after the trigger input.
· The trigger input is a TTL compatible signal.
