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.

SingleFrame - After an acquisition start event, the camera will only receive a single frame trigger event. Further trigger events will

be ignored until acquisition is stopped and restarted.

MultiFrame - After an acquisition start event, the camera will receive AcquisitionFrameCount number of triggers. Further trigger

events will be ignored until acquisition is stopped and restarted.
