Trigger Modes for GigE Vision Cameras
Note All triggering modes and parameters for GigE Vision cameras are subject to camera
vendor implementation. Refer to your camera documentation for triggering modes and
parameters available for your camera.
Most GigE Vision cameras that support triggering have the following
attributes:
• TriggerSelector—Specifies the type of trigger to control. Examples
of triggers to control are FrameStart, FrameEnd, FrameActive,
AcquisitionActive, LineStart, ExposureStart, ExposureEnd,
ExposureActive.
• TriggerMode—Specifies the operation mode of the trigger for
acquisition. Examples of operation modes are Off, Hardware, and
Software.
• TriggerActivation—Specifies the type of signal change. Examples of
signals are RisingEdge, FallingEdge, LevelHigh, and LevelLow.
• TriggerSource—Specifies the input line signal. Examples of input
line signals are Off, Line1, and Line2.
• TriggerSoftware—Generates a software trigger to start the
acquisition in software trigger mode.
