Section 6: Troubleshooting
This section reviews common problems in operating the SBE 63, and provides
the most likely causes and solutions.
Problem 1: Unable to Communicate with SBE 63
The
S>
prompt indicates that communications between the SBE 63 and
computer have been established. Before proceeding with troubleshooting,
attempt to establish communications again by clicking
Connect
in the
Communications menu in Seaterm232.
Cause/Solution 1
: The I/O cable connection may be loose. Check the cabling
between the SBE 63 and computer for a loose connection.
Cause/Solution 2
: The instrument type and/or its communication settings may
not have been entered correctly in the terminal program. Verify the settings in
the Serial Port Configuration dialog box (Communications menu ->
Configure
). The settings should match those on the instrument Configuration
Sheet.
Cause/Solution 3
: The I/O cable may not be the correct one.
•
The I/O cable supplied with the SBE 63’s optional sensor mount permits
connection to standard 9-pin RS-232 interfaces. See
Dimensions and
Connector
in
Section 2: Description of SBE 63
for the cable pinouts.
Problem 2: Unreasonable Data
The symptom of this problem is data that contains unreasonable values (for
example, values that are outside the expected range of the data).
Cause/Solution 1
: Data with unreasonable values may be caused by incorrect
calibration coefficients in the SBE 63 (if looking at data output in converted
format). Verify the calibration coefficients in the SBE 63, using
GetCC
.
Cause/Solution 2 (MicroCATs only)
: A data file with unreasonable values
for dissolved oxygen may be caused by incorrect calibration coefficients in the
MicroCAT (SBE 37-SMP-ODO, 37-IMP-ODO, 37-SIP-ODO). Send
GetCC
to verify the oxygen calibration coefficients in the MicroCAT match the
SBE 63 Calibration Certificates. Note that calibration coefficients do not affect
the raw data stored in MicroCAT memory.
•
If you have not yet overwritten the memory with new data, you can
correct the coefficients and then upload the data again.
•
If you have overwritten the memory with new data, you can manually
correct the coefficients in the .xmlcon configuration file (which is
generated when you upload the data from memory), and then reprocess
the data in SBE Data Processing’s Data Conversion module.
Notes:
•
You can use any terminal
program to set up the SBE 63;
set it to 8 data bits, no parity, 1
stop bit, and 9600 baud (default
SBE 63 baud rate). Instructions
here are for using SeatermV2.
