9. Send
Save Setup
to save all entered parameters. This is redundant as it is done automatically
by the
Deploy
command below, but gives you some assurance your settings have been saved.
10. Double check system clock date/time and deployment start date/time. Verify settings in all
four
Show
commands one final time.
11. Send
Deploy
to start the deployment. Watch for any error messages or for any unexpected re-
sponse. If practical, leave the computer connected with the terminal emulator recording ADV
output until the first burst has been started. Note: To stop the deployment, send a
BREAK
.
12. Disconnect the cable from the computer before turning the computer off.
13. Install the dummy plug and deploy the ADV.
14. After the deployment: recover the ADV, interconnect the system as described in §2.4.3, and
use
SONTERM
to send a
BREAK
to the ADV to stop data collection (although you may first want
to observe a collection cycle or two to confirm that the ADV is still collecting data).
15. You can now use
SONTERM
to extract the data from the recorder. Use the data conversion
software to look at the recorded data (see
ADVField Software Manual
).
2.5. Operating the ADVField Using the Direct Command Interface
As an alternative to the SonTek data acquisition software, you can write your own software using
the serial communication protocol and command interface documented in Section 3. This allows
the ADV to be controlled from a terminal emulator, data logger, or other custom program.
For a quick check using a terminal emulator, connect the serial cables as described in §2.3.1 (for
real-time operation) or §2.4.3 (for autonomous operation), set the terminal emulator software
(e.g.,
SONTERM
) to the correct serial port, and apply power. The default communication parame-
ters are: no parity, 8 data bits, 2 stop bits, 19200 baud (see §4.2 to change baud rate).
To establish communication, send a
BREAK
(
Alt+B
in
SONTERM
). The response should look similar
to the following.

at the prompt. See Section 3 for details on the direct command interface.
The direct command interface allows access to all data collection parameters.
After each
SaveSetup
,
Start
, or
Deploy
(autonomous systems only) command, the data collec-
tion parameters are stored to an EEPROM in the processing module. For instruments without the
internal recorder, the ADV enters the data collection mode immediately after powering up.
Whenever power is applied to ADVs with the internal recorder, the ADV enters the last opera-
tional state. The three operational states are: command mode (ready for input commands over
the serial port), data acquisition mode (actively collecting and outputting real-time data), and de-
ployment mode (for autonomous deployment using battery power and the optional internal re-
corder). If the ADV (before being powered off) was collecting data in data acquisition or de-
ployment mode, it will load the last data collection parameters from EEPROM and immediately
begin data collection. Therefore, it is only necessary to send commands at startup when data col-
lection parameters need to be changed.
