Section 3: Configure Inputs, Part I - Instrument Configuration (.con file)
SBE 45 MicroTSG Configuration
The SBE 45 transmits ASCII converted data in engineering units. It converts
the raw data internally to engineering units, based on the programmed
calibration coefficients. See the SBE 45 manual.
Time between scans. Must agree with SBE 45
setup (Interval=); see reply from DS.
Define data in SBE 45 data stream:
• Output conductivity - Must agree with SBE 45 setup
(OutputCond=).
• Output salinity– Must agree with SBE 45 setup
(OutputSal=).
• Output sound velocity– Must agree with SBE 45
setup (OutputSV=).
See reply from DS for setup programmed into SBE 45.

settings.
• Use junction box - Select if SBE 45 data is
transmitted to computer through optional 90402 –
SBE 45 Interface Box. Interface Box can append
optional SBE 38 and NMEA data to SBE 45
data stream.
• SBE 38 temperature added – Select if 90402 – SBE
45 Interface Box is connected to SBE 38 remote
temperature sensor. Interface Box appends SBE 38
data to data stream. SEASAVE (and Data
Conversion and Derive in SBE Data Processing)
uses remote temperature data when calculating
density and sound velocity.
• NMEA data added - Select if 90402 – SBE 45
Interface Box is connected to NMEA navigation
device. 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 to exit dialog box. If you made changes
and did not Save or Save As, SEASAVE
asks if you want to save changes.
Shown below is an example status (DS) response in SEATERM that
corresponds to the setup shown in the Configuration dialog box above. Shown
below the appropriate lines are the commands used in SEATERM to modify
the setup of parameters critical to use of the SBE 45 with SEASAVE, as well
as any explanatory information.

sample interval = 1 seconds
(Sample interval [Interval=] must match Sample interval seconds in .con file.)
output conductivity with each sample
(Enabling of conductivity output [OutputCond=] must match Output conductivity
in .con file.)
do not output salinity with each sample
(Enabling of salinity output [OutputSal=] must match Output salinity in
.con file.)
do not output sound velocity with each sample
(Enabling of sound velocity output [OutputSV=] must match Output sound velocity
in .con file.)

do not power off after taking a single sample
(Power off after taking a single sample must be disabled [SingleSample=N] to
acquire data in SEASAVE.)
do not power off after two minutes of inactivity
