Setting Up SBE 45 Configuration (.xmlcon or .con) File in Seasave
The Interface Box integrates optional NMEA navigation device data and
optional SBE 38 data into the SBE 45 data stream. Seasave, Sea-Bird’s real-
time data acquisition and display program, stores and displays this data along
with the SBE 45 data. Seasave requires a configuration file, which defines the
SBE 45 – which parameters are output by the SBE 45, and the data output rate
- and indicates whether NMEA and SBE 38 data is to be appended to the data
stream. Seasave (as well as our data processing software) uses the information
in the configuration file to interpret and process the data.
If the configuration
file does not match the actual instrument configuration, the software will
not be able to interpret and process the data correctly.
To verify the contents of the .xmlcon or .con configuration file:
1.
Double click on Seasave.exe.
2.
Click Configure Inputs. On the Instrument Configuration tab, click Open . In
the dialog box, select the .xmlcon or .con file and click Open.
3.
The configuration information appears on the Instrument Configuration
tab. Verify that the outputs match those programmed into your SBE 45,
and that the use of the Interface Box, and addition of remote temperature
and NMEA, are correct. Click Modify to bring up a dialog box (shown
below) to change the configuration.
4.
Click Save or Save As to save any changes to the .xmlcon or .con file.
Click Exit when done reviewing / modifying the configuration.
Define data in SBE 45 data
stream:
•
Output conductivity with each
scan - Must agree with SBE 45
setup (
OutputCond= ).
•
Output salinity with each scan –
Must agree with SBE 45 setup
(
OutputSal= ).
•
Output sound velocity with each
scan – Must agree with SBE 45
setup (
OutputSV= ).
See reply from DS for setup
programmed into SBE 45.
•
Use junction box - Select if SBE 45 data transmitted to computer through Interface Box.
•
SBE 38 temperature added – Select if Interface Box connected to SBE 38 remote
temperature sensor. If selected, Seasave and SBE Data Processing (Data Conversion and
Derive modules) use remote temperature data when calculating density and sound velocity.
•
NMEA data added - Select if Interface Box connected to a NMEA navigation device.
Seasave automatically adds current latitude, longitude, and universal time code to data
header. Select NMEA (Lat/Lon) Interface in Seasave’s Configure menu to control how
Lat/Lon data is incorporated.
New to create new

Time between scans. Must agree with SBE 45 setup ( Interval= );

Notes:
•
Seasave and SBE Data Processing
versions 7.20a introduced .xmlcon
files (in XML format). Versions 7.20a
and later allow you to open a .con or
.xmlcon file, and to save it to a .con
or .xmlcon file. Seasave and SBE
Data Processing use the same file.
•
A new or recalibrated CTD ships
with a configuration file that reflects
the current configuration
as we know
it . The file is named with the
instrument serial number, followed
by a .con extension. For example,
for a CTD with serial number 2375,
Sea-Bird names the file
2375.con .
You may rename the file (but not the
extension) if desired; this will not
affect the results.
