8.6. Events
When event notification is set to "on", the camera can generate an "event" and transmit a related event
message to the host whenever a specific situation has occurred. For MERCURY2 USB3 Vision camera,
the camera can generate and transmit events for the following situations:

The camera has ended exposure (ExposureEnd)

An image block is discarded (BlockDiscard)

The trigger signal overflow (FrameStartOvertrigger)

The image frame block is not empty (BlockNotEmpty)

The burst trigger signal overflow (FrameBurstStartOvertrigger)

The trigger signal wait (FrameStartWait)

The burst trigger signal wait (FrameBurstStartWait)
Every event has a corresponding enable status, and in default all the events' enable status are disable.
When using the event feature, you need to enable the corresponding event. The effective information
contained in each event is shown in Table 8-6:
