Problem 3: Unable to Communicate with SBE 38 through Interface Box
In SEATERM, while communicating with the Interface Box, send
Connect38 .
The following message should appear:
connected to SBE 38 . . .
This indicates that communications between the Interface Box and SBE 38
have been established. If this messages does not appear:
Cause/Solution 1 : The cable connection may be loose. Check the cabling
between the SBE 38 and Interface Box for a loose connection.
Cause/Solution 2 : The cable between the SBE 38 and Interface Box may not
be the correct one. Verify that the cable is the correct one.
Cause/Solution 3 : The baud rate for communication between the SBE 38 and
Interface Box may not match. The SBE 38’s baud rate (set with Baud= when
directly communicating with the SBE 38) must be the same as the baud rate
set in the Interface Box with
38Baud= .
Cause/Solution 4 : The SBE 38 baud rate may be too high. The baud rate for
communication between the Interface Box and computer must be greater than
the baud rate between the Interface Box and SBE 38.
•
Increase the Interface Box baud rate using PCBaud= . Or
•
Connect the SBE 38 directly to the computer and decrease its baud rate
using
Baud= . Then, with the Interface Box connected to the computer,
use 38Baud= to match the baud set in the SBE 38.
Problem 4: Unable to Communicate with NMEA Navigation Device through
Interface Box
See
Appendix I: NMEA Data for NMEA troubleshooting.
Problem 5: Nonsense or Unreasonable Data
The symptom of this problem is data that contains nonsense values (for
example, 9999.999) or unreasonable values (for example, values that are
outside the expected range of the data).
Cause/Solution 1 : A data file with nonsense values may be caused by
incorrect instrument configuration in the .xmlcon or .con file. Verify the
settings in the configuration file match your system.
Cause/Solution 2 : Unreasonable values may be caused by incorrect
calibration coefficients programmed into the instrument. Verify the calibration
coefficients in the SBE 45 and (optional) SBE 38 match the Calibration
Certificates. To verify calibration coefficients, use
DC while communicating
with each instrument (either directly connected to the computer or through the
Interface Box) in SEATERM.
Cause/Solution 3 : Unreasonable values may be caused by setting the
SBE 45’s output format to OutputFormat=2 , which is incompatible with the
Interface Box. Verify that the SBE 45 is set to OutputFormat=0 or
OutputFormat=1 by sending DS while communicating with the SBE 45
(if the SBE 45 is set to OutputFormat=2 , the last line of the DS response
shows conductivity and salinity order reversed ).
