Trigger input (Pin 10, 11)
This input allows control of the electronic or electromechanical shutter by an
externally applied signal. It is necessary to switch the camera into image-on-
demand mode to enable direct exposure control.
The signal is level-sensitive, thus the HIGH duration directly dictates the expo-
sure time of the camera.
The current through the opto coupler (1) should be greater than 1 mA and not
exceed 20 mA:
5 … 12V (HIGH)
Active exposure (only valid during IOD mode)
<0.8 V (LOW)
Inactive (falling edge starts frame output)
Note
For more information on image-on-demand mode: see Chapter
