public virtual void NotifyAcquisitionReady(
	int cameraIndex
)

Parameters

Camera index which is ready to receive triggers.
Exceptions
ExceptionCondition
ArgumentOutOfRangeException Thrown if camera index is less than 0 or greater than the number of supported camera acquisition channels.
CogFfpInvalidOperationException Thrown if the requested operation is invalid in the current state.
Remarks
Note that calling NotifyAcquisitionComplete() automatically re-enables triggers for a particular camera, so calling NotifyAcquisitionReady() is only required to enable the very first acquisition. After the first acquisition you must call NotifyAcquisitionComplete() for the trigger ready signal to be sent back to the remote device or PLC.
