7.9. Sequential Timed Exposure Mode
7.9.1 Video send mode
The sequential trigger mode has the following modes which are selected in the video send mode.
Depending on the mode selected, a different method is used to select the Sequence Index.
Trigger Sequence:
Select the index by using the Frame Start trigger signal. (The
setting index can be determined by the Next Index setting.)
Command Sequence:
Select the index number to assign directly by using the
Command Sequence Index command.

Note 1. Only EL-2800-USB
Note 2. Overlap mode=Readout is not available
Note 3. The minimum interval calculation assumes that the exposure times for all
sequences are equal. If there are differences, it is necessary to add the
differences 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 4. The sequence must start with Index 0. After Index 0 is executed, the
Sequence proceeds to the next setting index.
