Manual revision 006 Section 4: Deploying and Operating SBE 19plus V2 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. Typically only used to recover

data if you accidentally initialize logging

(using InitLogging) before uploading all

existing data. 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.

Biowiper=x x=Y: Configuration includes WET Labs

ECO-FL fluorometer with Bio-Wiper

(voltage or RS-232 auxiliary sensor). With

this setup, 19plus V2 is powered longer for

DS and GetSD, providing sufficient time

for Bio-Wiper to open and then shut again

if in Moored mode if Bio-Wiper is set up

to take 1 measurement for each sample

(see Application Note 72).

x=N (default): No ECO-FL with

Bio-Wiper.

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

• 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,

conserving battery energy if the user

does not send QS to put the 19plus V2

to sleep.

Note:

If an ECO-FL with Bio-Wiper is

installed and Biowiper=N, sending

GetSD or DS will open the Bio-Wiper,

but not provide enough powered time

to close it again. If you then deploy the

instrument in Moored mode (MM) with

the Bio-Wiper open and with a delayed

start time, the ECO-FL may become

fouled because the Bio-Wiper will

remain open until the first sample is

completed.
