Section 4: Deploying and Operating SBE 19plus V2
28
Profiling Mode
The SBE 19plus V2 samples data at 4 Hz (one sample every 0.25 seconds),
averages the data at pre-programmed intervals, stores the averaged data in its
FLASH memory, and transmits the averaged data real-time. The 19plus V2
provides several methods for starting and stopping logging, depending on the
settings for IgnoreSwitch= and AutoRun=:
IgnoreSwitch= AutoRun=
To Start Logging: To Stop Logging:
N N
Slide magnetic
switch on.
Slide magnetic switch off, or
send
Stop.
Y N
Send
StartNow, or
StartDateTime=
and
StartLater.
Send
Stop.
Y or N Y
Turn on external
power.
• Turn off external power, or
• (if you want to send
commands to check or
modify setup) Send
Stop.
Example: 19plus V2 in Profiling mode
Wake up 19plus V2. Set date and time to October 1, 2007 at 9:05 am. Initialize
logging to overwrite previous data in memory. Set up with strain-gauge pressure
sensor and 1 voltage sensor, average every 4 samples, and output data in raw hex
format. Set up with a 60-second pump turn-on delay after pump enters water, to
ensure pump is primed before turning on. Set up to initiate logging with the
magnetic switch. After all parameters are entered, verify setup with status
command. Send power-off command.
(Click Connect in Seaterm232’s Communications menu to connect and wake up.)

GETCD (to verify setup)
QS
Start logging by putting magnetic switch in On position. Put 19plus V2 in water,
and allow to soak for at least time required for pump turn-on (PumpDelay=60)
before beginning downcast. If desired, use SEASAVE to view real-time data.
When cast is complete, stop logging by putting magnetic switch in Off position.
Upload data in memory, in format SBE Data Processing and SEASAVE can use.
Send power-off command.
(Click Connect in Seaterm232’s Communications menu to connect and wake up.)
(Click Upload– Seaterm232 leads you through screens to define data to be
uploaded and where to store it.)
QS
Note:
Sea-Bird ships the 19plus V2
with AutoRun=N (it will not
automatically start sampling
when external power is
applied). If you send
AutoRun=Y:
• Send QS to put 19plus V2 in
quiescent (sleep) state, and
then turn power off and then
on again to start sampling.
or
•
Send StartNow to
start sampling.
Note:
Use Stop to:
• Stop sampling
• Stop waiting to start sampling
(after Startlater has been sent)
Once Stop is sent, the 19plus V2
accepts all commands again.
