If the single CoaxPress Trigger is used, the Synchronization mode using 2xTriggers can’t be used.
7.3.1
External Triggers on GPIO Connector
An External GPIO connector allows the camera to used 2 lines for triggering (Line0 and Line1)
The end-user has the responsibility of the definition of the triggering system.
The mapping describes all features available to define a trigger system
7.3.2
CXP Trigger Line
CXP specification allows the frame grabber to send triggers through the low speed link0 (@20MHz)
The CXP specification describes the behavior of the trigger, where only the edge of the signal and a timer to
limit the latency is described.
For the camera, the CXP trigger is consider to be the “line2”. The Frame grabber itself can also manage
several lines, timers, counter and finally send this single CXP trigger to the camera.
