Commands that Should be in a Command File
ADCPs mostly use the same set of commands, but there are minor differences.
Consult the technical manual for a particular ADCP for details of its commands. In addition, some commands are not appropriate for all ADCPs. For
example, only the Ocean Surveyor understands commands such as NP, EI, and
EJ. They will cause errors if sent to other kinds of ADCP.
For RDI recommendations on which commands should be used with which
ADCP, check the example command file for the ADCP.
Restore Factory Defaults
CR1
It is a good idea to restore the ADCP to the known factory default configuration
before starting. CR1 should be the first command in the file.
Data fields
WD
Edit this to turn on or off each kind of data to record in the output file.
Profile
WP
For VmDas to perform correctly, command files must set the ADCP for single
ping data. This means either a WP1 command must be present if velocity profile data is desired, or WP0 if not.
Most Navigators do not recognize the WP command unless they have the Water
Profiling upgrade installed. It should not be in command files intended for
Navigators without this upgrade.
NP
Command files for Ocean Surveyor should include NP1 or NP0. Other ADCPs
do not recognize this command, and should not have it.
WS, WF, WN, WV (or NS, NF, NN for Ocean Surveyor’s using the NP1
command)
These commands configure the velocity profile. Edit these to fit the ADCP and
deployment. Omit them for ADCPs that do not have water pings.
Bottom Track
BP
For VmDas to perform correctly, command files must set the ADCP for single
ping data. This means a BP1 command must be present if bottom track data is
desired, or BP0 if not.
