Sentinel V SC and RT Operation Manual

EAR-Controlled Technology Subject to Restrictions Contained on the Cover Page.
When a Sentinel V ADCP is configured for Real-Time mode, it is configured using Sentinel V RT Utilities
and uses the following Real-Time commands. Using Sentinel V RT Utilities for real-time deployments to
develop the command file will ensure that the Sentinel V Real-Time is set up correctly. The commands
shown in Table 21 directly affect the range of the Sentinel V Real-Time, the standard deviation (accuracy)
of the data, and battery usage.
Most Sentinel V Real-Time command settings use factory-set values (Table 21). If these values are
changed without thought, the deployment could be ruined. Be sure to know what effect each command
has before using it. Call TRDI for help on understanding the function of any command.
Data Communication and Command
Format
Enter commands using a Windows compatible computer with a serial interface running TRDI’s TRDI
Toolz or Sentinel V RT Utilities. The Sentinel V Real-Time communicates with the computer through the
RS-232/RS-422 serial interface I/O cable or Ethernet. TRDI initially sets the Sentinel V Real-Time at the
factory to communicate at 9600 baud, no parity, and one stop bit.
Immediately after power is applied to the Sentinel V Real-Time, it enters the STANDBY mode. Send a
software break by sending either “+++” or “===”. When the Sentinel V Real-Time first powers up or re-
ceives a BREAK signal, it responds with a wake-up message similar to the one shown below. The Sentinel
V Real-Time is now ready to accept commands at the “>” prompt from either a terminal or computer pro-
gram.>break

Command Input Processing
Input commands set Sentinel V Real-Time operating parameters, start data collection, run built-in tests
(BIT), and asks for output data. All commands are ASCII character(s) and must end with a carriage return
(CR). For example,
>CR1<CR> [Your input]
If the entered command is valid, the Sentinel V Real-Time executes the command. If the command is one
that does not provide output data, the Sentinel V Real-Time sends a carriage return line feed <CR> <LF>
and displays a new “>” prompt. Continuing the example,
>CR1<CR> [Your original input]
[Parameters set to FACTORY defaults]
> [Sentinel V Real-Time response to a valid, no-output command]
If a valid command is entered that produces output data, the Sentinel V Real-Time executes the com-
mand, displays the output data, and then redisplays the “>” prompt. Some examples of commands that
produce output data are
?
(help menus),
CS
(start pinging),
PS
(system configuration data), and
PA
(run
built-in tests).
