Section 4: Deploying and Operating SBE 19plus V2

General Setup Commands (continued)
InitLogging Initialize logging - after all previous data
has been uploaded, initialize logging
before starting to sample again to make
entire memory available for recording.
InitLogging sets sample number
(SampleNumber=) and header and cast
number (HeaderNumber=) to 0
(sampling will start with sample 1 and
cast/header 1). If not set to 0, data will be
stored after last recorded sample. Do not
send InitLogging until all existing data
has been uploaded.
SampleNumber=x x= sample number for last sample in
memory. After all previous data has been
uploaded, send SampleNumber=0 (sets
sample number and header / cast number
to 0) before starting to sample to make
entire memory available for recording
(sampling will start with sample 1 and
header 1). If not set to 0, data will be
stored after last recorded sample. Do not
send SampleNumber=0 until all existing
data has been uploaded.
HeaderNumber=x x= header and cast number for last cast or
header in memory. Typically used to
recover data if you accidentally initialize
logging (using InitLogging or
SampleNumber=0) before uploading all
existing data. 19plus V2 can have a
maximum of 1000 stored headers.
Note that 19plus V2 writes a new header:
- each time logging is started in
Profiling Mode
- each time logging is started and after
every 2000 samples are stored in memory
in Moored Mode.
QS Quit session and place 19plus V2 in
quiescent (sleep) state. Main power turned
off. Data logging and memory retention not
affected.
Notes:
• The 19plus V2 requires verification
when InitLogging,
SampleNumber=, or
HeaderNumber= are sent.
19plus V2 responds:
this command will change the
scan length and/or initialize
logging. Repeat the command to
verify.
Type the command again and press
the Enter key to proceed. The
19plus V2 responds:
Scan length has changed,
initializing logging
•
InitLogging and SampleNumber=0
have identical effects. Use either to
initialize logging.
• Do not initialize logging until all
data has been uploaded. These
commands do not delete data; they
reset the data pointer. If you
accidentally initialize logging
before uploading, recover data as
follows:
1. Set SampleNumber=a and
HeaderNumber=b, where a and b are
your estimate of number of samples
and casts in memory.
2. Upload data. If a is more than actual
number of samples or b is more than
actual number of casts in memory,
data for non-existent samples/casts
will be bad, random data. Review
uploaded data file carefully and delete
any bad data.
3. If desired, increase a and/or b and
upload data again, to see if there is
additional valid data in memory.
Note:
The 19plus V2 automatically enters
quiescent (sleep) state after 2 minutes
without receiving a command. This
timeout algorithm is designed to
conserve battery energy if the user
does not send QS to put the 19plus V2
to sleep.
