7.8 Sequential Timed Exposure mode
This is a function to capture images in sequence based preset ROI, Exposure Time, Gain and other
parameters in the sequence index table.
In order activate this function, Video Send Mode should be set at Trigger Sequence.

Note 1. Overlap mode=Readout is not available
Note 2. The minimum interval calculation assumes that the exposure time for all sequences are
equal. If there are differences, it is necessary to add the diference to the calculation.
If
the exposure times are different, it is recommended to organize the exposure times
from the shortest exposure to the longest one.
Note 3. The sequence must start with Index 0. After Index 0 is executed, the sequence
proceeds to the next setting index.
In this mode, while the previous trigger operation (Index table) is activating, the next trigger
cannot be overlapped. Sequence index table must be through index 0 and after index 0 is
performed, the next index can be operated.
