Expose Out Behaviors

Note: All timing diagrams below shown with Edge triggering mode
First Row
"Expose Out" I/O signal leaving the camera is high only when the first row of a single frame is being exposed.
The length of the signal is equal to the exposure time for the first row. Exposure time is equal to what is set
in the software application. Although this Expose Out mode enables maximum camera frame rates, it does
not avoid the overlap due to rolling shutter. This mode is not recommended if trying to alternate between
excitation wavelengths.

Any Row
"Expose Out" I/O signal leaving the camera is high when any row in a single frame is exposing. The length of
the Expose Out signal is equal to the time between the start of the first row's exposure and the end of the last
row's exposure. Each line exposes for the same amount of time which is equal to what is set in the software
application. Maximum camera frame rates are not possible in this mode but this does avoid frame overlap.
