Sequence Advance
As explained above, a sequence set can only control the operation of the camera after its parameter
values were loaded into the active set. The loading into the active set and therefore the selection of
a sequence set as the current set for a specific image acquisition are performed according to the
selected sequence advance mode. The selection of a sequence set as the current set is always
linked to the frame start trigger signals unless software commands are used (see below).
Accordingly, a sequence advance mode provides a scheme for advancing from one sequence set
to the next as frames are triggered.
The following sequence advance modes are available:
Auto: Sequence set advance is automatically controlled by the camera. The camera will cycle
through the available sequence sets in ascending sequence set index number as frames are
triggered. Individual sequence sets can be used consecutively. After one sequence set cycle is
complete another one will start automatically.
Controlled: Sequence set advance is controlled by a source that can be selected. The
available sources are automatic control by the camera (the "always active" setting), an input
line or the "disabled" setting allowing sequence set advance only by software commands.The
camera will cycle through the available sequence sets in ascending sequence set index
number as frames are triggered. After one sequence set cycle is complete another one will
start automatically.
Free selection: Sequence set advance by selecting sequence sets at will from the available
sequence sets. The selection is controlled by the states of the input lines.
The regular cycling through the sequence sets according to the Auto or Controlled advance modes
can by modified at any time during the cycling:
a restart starts a new sequence set cycle before the previous cycle is completed. The restart
can be controlled by the states of an input line (controlled sequence advance only) or by a
software command.
a non-cyclical advance allows to skip a sequence set and will advance to the sequence set
after the next. The non-cyclical advance can be controlled by a software command.
Advance or restart controlled by an input line are also called "sychronous advance" and
"sychronous restart" because the checking of the states of an input line is always linked to a frame
trigger signal.
Advance or restart controlled by a software command are also called "asychronous advance" and
"asychronous restart" because they are not linked to a frame start trigger signal.
Because the sequence sets only reside in volatile memory they are lost if the
camera is reset or switched off. If you are using the sequencer feature, you must
populate the sequence sets after each camera reset or startup.
Note also that sequence sets can not be saved in user sets.
