j
All event buffers and waveforms are stored in a serial sequence retaining the most recent data.
k
Data buffers from the event are retained independent of whether waveform data was or could be captured at the time of the event.
l
Data is approximate for most styles of CAM module. Consult the specific CAM module literature for more information.
m
Discrete logging data is not stored and not viewable in the display module.
n
Prime and Basic events share the same memory space. The maximum number stored will dependent upon the maximum number received of each event.
