To synchronize the cameras you have different possibilities:
•Enable the trigger output on one of the cameras and set all other cameras to hardware triggered on the falling edge. The camera outputting the trigger signal can then be operated software triggered, and all other cameras will operate synchronously to this camera.
•Supply an external trigger signal via another Y-Adapter. In this case all cameras should be set to hardware triggered.
Note: The internal electrical connections of all cables used in the following figures are described under the cables topic.
Here you can see different wiring examples for synchronizing multiple stereo and monocular cameras using the hardware trigger signal.
