10.10.1 Vertical Beam Command Descriptions
This section lists the Vertical Beam commands.
VD – Vertical Beam Data Out
Purpose Selects the vertical beam data types included in a PD0
ensemble.
Format VD abcdefghi
Range Firmware switches (see description)
Default VD 111000000
Recommended Setting. The default setting for this command is
recommended for most applications.
Description The VD command uses firmware switches to tell the Channel
Master the types of vertical beam data to include in a PD0 en-
semble. PD0 ensembles always contain a header, fixed and
variable leader, and checksum. The bits are described as fol-
lows:
a = surface track amplitude d = Reserved g = Reserved
b = surface track commands e = Reserved h = Reserved
c = surface track status f = Reserved I = Reserved
Example VD 111000000 (default) tells the Channel Master to include
surface track amplitude, surface track commands, and surface
track status.
NOTE.
1. Each bit can have a value of one or zero. Setting a bit to one means
output data, zero means suppress data.
2. IF VP = zero, the Channel Master does not collect vertical beam data,
and VD has no effect (see “VP – Vertical Beam Number of Pings per
Ensemble,” page 88). No vertical beam data is included.
3. The VD command does not affect the contents of PD14, PD19, or
SDI-12 data.
4. See the WD command for water profile and firmware version data (see
“WD – Data Out,” page 92).
