EXTERNAL TRIGGERING

When the cellSens / OLYMPUS Stream software is used, the DP73 can record still images or control a commer-
cially 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 /
OLYMPUS 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.
