Standard Features
236 Basler scout
However if you are operating the camera at high frame rates with a small AOI, the camera may be
able to generate and queue events faster than they can be transmitted and acknowledged. In this
case:
1. The queue will fill and events will be dropped.
2. An event overrun will occur.
3. Assuming that you have event overrun reporting enabled, the camera will generate an "event
overrun event" and place it in the queue.
4. As soon as transmission time is available, an event message containing the event overrun
event will be transmitted to the PC.
The event overrun event is simply a warning that events are being dropped. The notification
contains no specific information about how many or which events have been dropped.
Setting Your System for Event Reporting
Event reporting must be enabled in the camera and some additional software-related settings must
be made. This is described in the "Camera Events" code sample included with the pylon software
development kit.
Event reporting must be specifically set up for each type of event using the parameter name of the
event and of the supplementary information. The following table lists the relevant parameter names:
You can enable event reporting and make the additional settings from within your application
software by using the pylon API. For more information, see the "Camera Events" code sample
included with the pylon software development kit.
For more detailed information about using the pylon API, refer to the Basler pylon Programmer’s
Guide and API Reference.
