EdgeAny – rising or falling edge
LevelHigh – active high signal
LevelLow – active low signal
AcqStartTriggerMode - Selects if the start of acquisition should be stimulated by an external hardware
trigger. See the AcquisitionStart command for software triggering.
SyncIn1 – trigger at SyncIn1 to be associated with this control
SyncIn2 – trigger at SyncIn2 to be associated with this control
Disabled – an external trigger does not control start of acquisition
FrameRate
When FrameStartTriggerMode is set to FixedRate, this control specifies the frame rate.
FrameStart
Controls relating to the triggering of frames within an acquisition.
FrameStartTriggerDelay - Start-of-image is delayed FrameStartTriggerDelay microseconds after
receiving an external trigger event. This feature valid only when FrameStartTriggerMode is set to external
trigger (i.e. SyncIn1, SyncIn2). Useful when using a common trigger to synch with a strobe lighting
source, which will inherently have some fixed setup time.
FrameStartTriggerEvent - The external trigger can be configured to accept various trigger event types:
EdgeRising – rising edge trigger
EdgeFalling – falling edge trigger
EdgeAny – rising or falling edge
LevelHigh – active high signal
LevelLow – active low signal
FrameStartTriggerMode - Determines how an image frame is initiated within an acquisition.
Freerun – camera runs at maximum supported frame rate depending on the exposure time and region
of interest size.
SyncIn1 - external trigger SyncIn1
SyncIn2 - external trigger SyncIn2
FixedRate - camera self-triggers at a fixed frame rate defined by FrameRate.
Software - software initiated image capture.
FrameStartTriggerSoftware – A command. Valid when FrameStartTriggerMode equals Software. In
SampleViewer, when selected a button appears at the bottom of the controls window that snaps a single
image when pressed.
AcquisitionAbort – A command. In SampleViewer, when selected a button appears at the bottom of the
controls window that aborts the acquisition when pressed.
AcquisitionFrameCount - Define the number of frames to capture when capturing a limited sequence of
images. Used in combination with MultiFrame and Recorder acquisition modes.
AcquisitionMode
The acquisition modes, which determine how the camera handles frame triggers within the acquisition stream.
Continuous – After an acquisition start event, the camera will continuously receive frame trigger events,
or in the case where FrameStartTriggerMode equals Freerun, will continuously stream. This is the normal
acquisition mode of the camera.
