An Acquisition is defined as the capture of a sequence of one or many Frame (s). This Acquisition mode and
its command is managed by the Frame Grabber.
A
Frame is defined as the capture of Width pixels x Height lines.
As for the Acquisition Mode, the Frame Management (Start, stop …) is also manage by the Frame Grabber.
The CXP Camera is considered as a LineScan Camera (as in the CameraLink version) then only deals
with the Line/Exposure Triggers.
A
Line starts with an optional Exposure period and ends with the completion of the sensor read out.
The Line/Exposure Triggers can be connected :
Either on the GPIO connector of the Camera (2x Lines Triggers : Line0/1 available if Forward/reverse
command is controlled by software)
Or by the CoaxPess Cable : Only one Trigger available (Line2).
If the single CoaxPress Trigger is used, the Synchronization mode using 2xTriggers can’t be used.
