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.
Note For more information on image-on-demand mode: see Chapter
Mode setting

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)
