10.8.1 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 is 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.
10.8.1.1 Operation
Operating the Sequencer
The following use case (see also Figure 97) 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.
Assuming that the camera is in the process of continuously capturing images, the sequencer
feature operates as follows:
When the sequencer feature becomes enabled, the sequence set cycle starts: The parameter
values of the sequence set with sequence set index number 0 are loaded into the active set
modifying the active set.
When a frame start trigger is received, sequence set 0 is used for the image acquisition.
When the next frame start trigger was received, the camera checks the current Sequence Set
Executions parameter value. Because the Sequence Set Executions parameter was set to 1
for sequence set 0, this sequence set is only used once and therefore the camera advances to
the next sequence set: The parameter values of sequence set 1 are loaded into the active set
and are used for the image acquisition.
When the next frame start trigger was received, the camera checks the current Sequence Set
Executions parameter value. Because the Sequence Set Executions parameter was set to 3
for sequence set 1, this sequence set is used a second time: The parameter values of
sequence set 1 are used for the image acquisition.
When the next frame start trigger was received, the camera checks the current Sequence Set
Executions parameter value. Because the Sequence Set Executions parameter was set to 3
