3.5. Trigger Modes
The P3I3 family members support various trigger modes to satisfy the requirements of varying
applications. There are three main modes of operation to distinguish: Softtrigger, Exttrigger and
Autotrigger. For all three modes the necessary timing informations for the camera control signals has to
be set by software before operation begins. Refer to the sofware section for adjustable parameters. Both
frame grabbers are capable of handling a frame and a line trigger. The trigger inputs are selectable via
software and are located either at the connector(s) at the frontpanel or the 16 pos. connector.
3.5.1. Softtrigger
In the "Softtrigger Mode" the software defines the starting point of the generated timing. The grabber
repeats this timing until it is stopped again by the software.
3.5.2. Exttrigger
In the "Exttrigger Mode" acquisition and timing is started by external events on the falling or rising edge of
the selected trigger input. After the programmed timing has expired the grabber waits for the next trigger
edge to repeat the control cycle. Working with two triggers, e.g. frame trigger and line trigger, is also
possible.
3.5.3. Autotrigger
In the "Autotrigger Mode" acquisition and timing is started by external events on the falling or rising edge
of the selected trigger input. After the programmed timing has expired the grabber repeats the control
cycle immediately. Working with two trigger, e.g. frame trigger and line trigger, is also possible.
