Appendix C. FP2 Data Format
FP2 data are two-byte big-endian values. See
Endianness
(p. 559).
Representing
bits in each byte pair as ABCDEFGH IJKLMNOP, bits are described in table
FP2
Data-Format Bit Descriptions
(p. 557).

B, C
Decimal locaters as defined in the table FP2 Decimal Locater Bits.
D - P
13-bit binary value, D being the
MSB
(p. 283).
Largest 13-bit
magnitude is 8191, but Campbell Scientific defines the largest-
allowable magnitude as 7999
Decimal locaters can be viewed as a negative base-10 exponent with decimal
locations as shown in
TABLE: FP2 Decimal Locater Bits
(p. 557).
