Camera Event Overflow Signaled when the Genie HM can not generate or transmit all requested events. All
active events are automatically disabled and need to be re-activated by the
application. To prevent an overflow, a lower acquisition frame rate or simply less
individual events should be used.
An Event overflow condition can occur in conditions such as:
 A high frame rate when many events are active per frame.
 The camera CPU can not process all Genie events.
 Conditions where the Genie internal event queue is exceeded.
 Conditions where Genie events exceed the hard limit of 512.
 Combinations of all of the above.
Event Selection via GigE Vision Compliant Applications
XML features for Events:
EventSelector = {None = 0, FrameTrigger = 2, ExposureStart = 3, ExposureEnd = 4,
InvalidFRameTrigger = 0x9008, AcquisitionEnd = 0x9003}
EventNotification = {Off = 0, GigEVisionEvent = 1}
Event_FrameTrigger_TimeStamp = Generate an Event on a frame trigger
Event_ExposureStart_TimeStamp = Event on exposure start
Event_ExposureEnd_TimeStamp = Event on exposure end
Event_InvalidTrigger_TimeStamp = Event when invalid trigger received
