NOTE
The binary value of these bytes is the number of bytes to follow including the
CRC check bytes. This value is transmitted as MSB first and LSB last. The
maximum byte count is 122 .
1 2 (A) AS (Accept State Command)
3 2 (I) Binary byte count (refer to Note)
CRC STARTS ACCUMULATING WITH NEXT BYTE
5 7 (I/B) Date/time information
12 1 (S) This is time positional data
13
1 (S) Count all states, not time between states
14 1 (S) Counter values already converted to
floating point
15 4 (R) Time positional measurement period
in seconds
19 1
(S) Overview was program activity, not
all states
20
1 (I) Type of data (4 = State Linkage Overview)
21 4 (B) Total number of samples taken
25
4 (R) Total number of linkage events found
29 8 Internal
37 N Data acquired
N = (Number of valid states) * M
Where : M = Number of linkage events
Each linkage event contains :
2 Internal
4
(R) Number of samples in this linkage event
5
(A) the name of this linkage event
