page 224) or when loading a sequencer set into the active set (see Section 7.7.3.3 on
page 227).
The Sequencer Set Path parameter selects a path by its index number. Two different paths are
available, path 0 and path 1. Each path allows to configure a distinct scheme for advancing
from one sequencer set to the next.
Path 0 and path 1 serve different purposes and should be configured accordingly:
Path 1 provides the scheme that allows to cycle through the available sequencer sets. This
is the mechanism for the standard use of the sequencer feature,
Path 0 allows to return to sequencer set 0 at any time and therefore provides a way for
resetting the cycling through the sequencer sets that is carried out according to path 1.
For each path, the following parameters must be set (see also Figure 87):
SequencerSetNext: Selects the sequencer set to be loaded next into the active set after the
present one when a trigger occurs for the related trigger source (see next entry). The next
sequencer set will replace the present one in the active set.
SequencerTriggerSource: Selects the trigger source for the trigger that will load the next
sequencer set into the active set. The following sequencer trigger sources are available (for
more information, see the section below). Note however, that different sets of trigger
sources are available for path 0 and path1 (for the differences, see Table 49 on page 221):
Line 1: Line IN
Line 3: GPIO
Line 4: GPIO
Software Signal 1: Software command
Software Signal 2: Software command
Software Signal 3: Software command (not available on acA1920-155 cameras).
Counter 2 End
Frame Start
Note that Line 3 and Line 4 can be selected regardless of whether they are configured for
input or output.
For each selected sequencer trigger source, the following parameter must be set (see also
Figure 87):
SequencerTriggerActivation: Selects the line status required to trigger loading of the next
sequencer set into the active set. The only available parameter value is Level High.
Basler strongly encourages setting different sequencer trigger sources for
path 0 and path 1.
