Camera Trigger Method #2
Camera Trigger Method #2
This method generates an asynchronous trigger pulse to a camera. The next generated
frame will be acquired. The trigger pulse using this method controls the number of lines
output by the camera and is usually used to control the length of the frame output by the
camera. The trigger duration specifies the minimum time in between 2 triggers for the
camera to operate properly.

Line Integration Method #1
Line Integration Method #1
This method generates 2 pulses. The distance between the end of the first pulse(#0) and
the start of the second pulse (#1) is the integration time. The 2nd pulse is also the Line
Trigger input to the camera. For example, on a Dalsa camera, the 1st pulse would be the
'Prin' signal while the 2nd pulse would be the 'Exesync' signal.
