The Burst message logger DataMode™ is used to store message data for transient events in an efficient manner. It can capture message data before and after user-defined triggering events occur. It is particularly useful in minimizing data storage consumption when video channels are used.
NOTE
When a large number of channels are selected for a DataMode, the GUI responsiveness can become sluggish. Typically with 500 channels or less, this is not overly intrusive to usability. However, if more than 500 channels are required for any given DataMode, it is recommended that users consider splitting the channels across multiple DataModes when possible; otherwise, users will need to be patient in regard to the GUI response when assigning or editing any of the DataMode parameters.
Trigger time
NOTE
Typically, some messages or video frames will be stored before the defined pre-trigger time and after the defined post-trigger time. The reason for this is a bit complex, but in brief, it’s much more efficient to process the message data in blocks compared to processing one message (or one video frame) at a time. The storage overhead will typically be very minimal.
