FrameStartWait Event
When the camera is in FrameTrigger mode, the camera starts acquiring images, and if it does not receive
the FrameTrigger signal, the camera will send a FrameStartWait event to the host.
8.6.8.
FrameBurstStartWait Event
When the camera is in the AcquisitionTrigger mode, the camera starts acquiring images. If the camera
does not receive the AcquisitionTrigger signal, the camera sends a FrameBurstStartWait event to the host.
Note that if the FrameTrigger mode is set to on simultaneously with the AcquisitionTrigger mode, the
FrameBurstStartWait event will be sent first. When the camera receives an AcquisitionTrigger signal, it will
send a FrameBurstStartWait event.

Sequencer
The Sequencer feature allows you to define sets of parameter settings and apply them to a sequence of
image acquisitions. As the camera acquires images, it applies one sequence set after the other, as shown
in Figure 8-75.

Features
[SequencerMode] Set the parameter to "On", enable the sequencer. Set the parameter to "Off", disable
the sequencer. When enabled, the sequencer controls image acquisitions, switch to next sequence set
after each image is acquired. When disabled, the sequencer is not controlling image acquisitions and
cannot switch parameters.
[SequencerConfigurationMode] Set the parameter to "On", "SequencerSetSave" and "SequencerSetLoad"
are enabled. Set the parameter to "Off", "SequencerSetSave" and "SequencerSetLoad" are disabled and
parameters cannot be saved to the sequence sets.
[SequencerFeatureSelector] Configure the feature that support sequence, like ExposureTime, Gain,
Gamma and FCC.
[SequencerFeatureEnabled] Set the parameter to “true”, the feature in "SequencerFeatureSelector" is
supported sequence, currently only true are supported and cannot be changed.
[SequencerSetSelector] Set the sequence set number. The range is determined by the camera model.
[SequencerSetSave] Save parameters to the sequence set in "SequencerSetSelector"
