Use Case Diagrams Illustrating Sequencer Operation
The sections below explain the sequence advance modes in detail. Use case descriptions and
diagrams are designed to illustrate how the sequence advance modes work in some common
situations and with some common combinations of parameter settings.
These use cases do not represent every possible combination of the parameters associated with
sequence advance mode operation. They are simply intended to aid you in developing an initial
understanding of how the sequence advance modes work.
In each use case diagram, the black box in the upper left corner indicates how the parameters are
set.
10.10.1 Auto Sequence Advance Mode
When the auto sequence advance mode is selected the advance from one sequence set to the next
occurs automatically as frame triggers are received. The advance proceeds in ascending sequence
set index numbers and subject to the Sequence Set Executions parameter value. It specifies how
many times each sequence set is consecutively used. After the sequence set with the highest index
number was used as many times as specified by the Sequence Set Executions parameter value,
the sequence set cycle starts again with sequence set 0.
The Sequence Set Total Number parameter specifies the total number of different sequence sets
that are available and included within a sequence set cycle. The maximum number is 64.
10.10.1.1 Operation
Operating the Sequencer
The following use case (see also Figure 45 on page 200) illustrates the operation of the sequencer
in auto sequence advance mode. As images are captured continuously, the camera advances
automatically with no action by the user from one sequence set to the next in ascending sequence
set index numbers. The advance is also subject to the Sequence Set Executions parameter
settings. After one sequence set cycle is complete, another one starts.
In this use case, the Sequence Set Total Number parameter was set to six. Accordingly, the
available sequence set index numbers range from 0 through 5. The Sequence Set Executions
parameter was set to 1 for sequence sets 0, 2, 3, and 4, to 2 for sequence set 5, and to 3 for
sequence set 1. The frame start trigger is set for rising edge triggering.
The use case diagrams are representational. They are not drawn to scale and are
not designed to accurately describe precise camera timings.
