Trigger output signal is used to mark the time during which the device is in acquisition. Once the acquisition starts, the signal changes from logic 0 to logic 1. After it finishes it changes from logic 1 to logic 0.
The acquisition is defined as follows:
In camera mode → the time during which the laser sweeps the scene and the 3D data are gathered.
In scanner mode → the time it takes to project all necessary patterns as well as LED texture.
