This data is output only if the BP-command is > 0 and PD0 is selected. See Table 43 for a
description of the fields.
The PD0 output data format assumes that the instrument is stationary and the bottom is
moving. DVL (Speed Log) output data formats (see
the bottom is stationary and that the H-ADCP or vessel is moving.
The H-ADCP uses these commands for "range" to boundary applications. The H-ADCP is NOT
designed for moving vessel Bottom Track applications.
This data is output only if the BP-command is greater than zero and PD0 is selected. The LSB is always
sent first.

Field Description
ID Code Stores the bottom-track data identification word (00 06h).
BP/BT Pings per Stores the number of bottom-track pings to average together in each ensemble (BP-
ensemble command). If BP = 0, the H-ADCP does not collect bottom-track data. The H-ADCP
automatically extends the ensemble interval (TE) if BP x TP > TE.
Scaling: LSD = 1 ping; Range = 0 to 999 pings
BD/BT delay before Stores the number of H-ADCP ensembles to wait after losing the bottom before trying
reacquire to reacquire it (BD-command).
Scaling: LSD = 1 ensemble; Range = 0 to 999 ensembles
BC/BT Corr Mag Min Stores the minimum correlation magnitude value (BC-command).
Scaling: LSD = 1 count; Range = 0 to 255 counts
BA/BT Eval Amp Min Stores the minimum evaluation amplitude value (BA-command).
Scaling: LSD = 1 count; Range = 1 to 255 counts
BG/BT %Gd Mini- Stores the minimum percentage of bottom-track pings in an ensemble that must be
mum good to output velocity data (BG-command).
BM/BT Mode Stores the bottom-tracking mode (BM-command).
