SBE 9plus Configuration
• Surface PAR - Select if Surface
PAR sensor used; must agree
with ADDSPAR= command
programmed into Deck Unit.
SEASAVE appends Surface PAR
data to every scan. Adds 2
channels to Channel/Sensor table.
Do not decrease Voltage words
suppressed to reflect this; Voltage
words suppressed reflects only
external voltages going directly to
9plus from auxiliary sensors.
See Application Note 11S.
• NMEA - Select if NMEA
navigation device used.
SEASAVE adds current latitude,
longitude, and universal time code
to data header; appends NMEA
data to every scan; and writes
NMEA data to .nav file every time
Ctrl F7 is pressed or Add to .nav
File is clicked (see Adding NMEA
Data to .nav File in Section 8:
Real-Time Data and Real-Time
Control - Real-Time Data
Acquisition).
Click a sensor and click Modify
to view/change calibration
coefficients for that sensor.
Shaded sensors cannot be removed or
changed to another type; others are optional.
IEEE-448 or RS-232C for CTD data
interface between Deck Unit and com
p
uter.
For full rate (24 Hz) data, set to 1.
Example: If number of scans to
average=24, SEASAVE averages
24 scans, saving data to computer at
1 scan/second.
Channel/Sensor table reflects this choice. Voltage 0 in
.con file corresponds to sensor wired to channel 0 on end
cap connector, voltage 1 to sensor wired to channel 1 on
end cap connector, etc. Total voltage words = 4; each
word contains data from two 12-bit A/D channels. Deck
Unit suppresses words above highest numbered voltage
word used. Words to suppress = 4 - Words to Keep
External Voltage Connector Words to Keep
(not spare)
0 or 1 AUX 1 1
2 or 3 AUX 2 2
4 or 5 AUX 3 3
6 or 7 AUX 4 4
Select to include time of each scan (seconds
since Januar
y
1, 1970 GMT
)
with data.
Click a (non-shaded) sensor and click Select to pick a
different sensor for that channel; dialog box with list of
sensors appears. After sensor is selected, dialog box for
calibration coefficients appears. Select sensors after
Frequency channels suppressed and Voltage words
suppressed have been specified above.
New to create new
.con file for this CTD.
Open to select
different .con file.
Save or Save As to
save current .con file
settings.
Opens a .txt file (for viewing
and printing only; cannot be
modified) that shows all
parameters in .con file.
Click to exit dialog box. If you made changes
and did not Save or Save As, SEASAVE asks if
you want to save changes.
Channel/Sensor table reflects this
choice. Typically:
• 0 = SBE 3 or 4 plugged into JB5
on 9plus (dual redundant sensor
configuration)
• 1 = SBE 3 or 4 plugged into
JB4 on 9plus and not using JB5
(single redundant sensor
configuration)
• 2 = no redundant T or C sensors
