DVL Output Data Format (PD4/PD5) Details

The H-ADCP sends this data format only when the PD4 or PD5 command is used.

Figure 56. DVL Binary Data Format (PD4/PD5)
Description
Stores the DVL (speed log) identification word (7Dh).
Identifies which data pattern will follow based on the PD-command.
0 = PD4 = Bytes 1 through 47 from Figure 56.
1 = PD5 = Bytes 1 through 45 from Figure 56 and
bytes 46 through 88 from Figure 57.
Note: PD6 is ASCII-only; see Table 49.
Contains the number of bytes sent in this data structure, not including the final checksum.
Defines the DVL hardware/firmware configuration. Convert to binary and interpret as
follows.
