A2.1.2 Data Sample, Event Counter, and Analog Input Module Structures
An ADV data sample includes one to three structures based on which optional sensors are in-
stalled: ADV data structure, compass structure, and sensor structure. The optional sensors are
available only with the ADVField. The data sample can take one of the four forms shown below.
No Sensors Installed (18 bytes)
•
