Full burst of everything per gas detection scan loop:
StatCast Burst of all gas
detector records and global

sent out RS232.

Sliding-Window Burst per gas detection scan loop:
StatCast Burst of Records
Size =
num_records_per_scan
(lastnum+1) through (lastnum+1+
num_records_per_scan). Lastnum
is incremented by Size.

Therefore, if the number of records (size) to be sent per gas detection scan loop is
50 for example, and there are 100 detectors on the bus, it would require two full gas
detector scans to output all gas level and status records.
