Notes:
Example:
When within snapshots modes 1 and 2 the user can choose to perform more than one fast
frame dump during a dump sequence. In some cases increasing the number of fast frame
dumps may help reduce the small residuals left behind after long EXSYNC idle times. In
general the user is recommended to use the factory default setting: snd 1.
Note that increasing the number of dumps will decrease the maximum frame rate that
can be achieved (this can be queried using the help screen in sem 2)..

3.6 Setting a Vertical Window of Interest

A window of interest is a subset of a full frame image that is desired as output from the
camera. Because the sensor is outputting only the designated window of interest, the
benefit is an increase in frame rate and a reduction in data volume.
To allow quick activation of new window coordinates, the camera allows you to preset
one sequence of window coordinates. These coordinates wait for a trigger and because
they have been preprogrammed, the new window is activated extremely quickly.
