To communicate exclusively with the video source(s), Zebra Rapixo CoF supports CoaXPress trigger signals going to the camera and control messages. Trigger packets, which are sent to the camera, are virtually represented as trigger signals. Control messages constitute the basic communication mechanism between the video source(s) and the board.
For each video source connected to the board, Zebra Rapixo CoF supports a CoaXPress trigger output signal. A CoaXPress trigger output signal can be sent from the board to a video source to initiate image acquisition or to optionally control the exposure time.
To send a trigger output signal to the camera, you use the Aurora Imaging Library-Lite function MdigControl() with M_IO_SOURCE + M_TL_....For more information on how to use the auxiliary input and output signals, refer to the Auxiliary signals section, later in this chapter.
