7.17 Event Notification

When event notification is set to "on", the camera can generate an "event" and transmit a related
event message to the computer whenever a specific situation has occurred.
The camera can generate and transmit events for the following types of situations:
The camera is ready to receive a frame start trigger (FrameStartWait event).

A frame start trigger has occurred (FrameStart event).

Overtriggering of the frame start trigger has occurred (FrameStartOvertrigger event).

This happens, if the camera receives a frame start trigger signal when it is not in a "waiting for
frame start trigger" acquisition status.
If the frame start overtrigger event is only available when image acquisition is
carried out using an external hardware trigger.
The camera is ready to receive a frame burst start trigger (FrameBurstStartWait event).

A frame burst start trigger has occurred (FrameBurstStart event).

Overtriggering of the frame burst start trigger has occurred (FrameBurstStartOvertrigger

event).
This happens, if the camera receives a frame burst start trigger signal when it is not in a "waiting
for frame burst start trigger" acquisition status.
The end of an exposure has occurred (ExposureEnd event).

The camera's device temperature has reached a critical level (Critical Temperature event) or,

upon further heating, the camera has entered the over temperature mode (Over Temperature
event). For more information about the related temperature levels and the over temperature
mode, see Section 1.11.3 on
An event message will be sent to the computer when transmission time is available. Note, however
that event messages can be lost when the camera operates at high frame rates. No mechanism is
available to monitor the number of event messages lost.
Note also that an event message is only useful when its cause still applies at the time when the
event is received by the computer.
