Trigger
This group of controls relates to how an image frame is initiated or triggered.
TriggerActivation [Enum] R/W
Type of activation, for hardware triggers. This controls edge/level and polarity
sensitivities.
TriggerDelayAbs [Float] R/W
Start-of-image can be delayed to begin some time after a trigger event is
received by the camera. This feature is valid only when TriggerSource is
set to external trigger (i.e. Line1, Line2). This control is a common trigger
to sync with a strobe lighting source, which will inherently have some fixed
setup time.
TriggerMode [Enum] R/W
Enables or disables trigger set in TriggerSelector.
TriggerOverlap [Enum] R/W
Permitted window of trigger activation, relative to previous frame. Does not
work with Software triggering. Only external.
RisingEdge [Default] Rising edge trigger
FallingEdge Falling edge trigger
AnyEdge Rising or falling edge
LevelHigh Active high signal
LevelLow Active low signal
Range:[0 – Camera dependent] Default: 0 Units: µs
Off Trigger disabled
On [Default] Trigger enabled
Note

If TriggerMode = Off and TriggerSelector =
FrameStart, images triggered in FixedRate at
AcquisitionFrameRateAbs.
Off [Default] Any external trigger received before a high
FrameTriggerReady signal is ignored
PreviousFrame Any external trigger received before FrameTrigger-
Ready is latched and used to trigger the next frame
