Section 6: Troubleshooting
This section reviews common problems in operating the Interface Box, and
provides the most likely causes and solutions.
Problem 1: Unable to Communicate with Interface Box
The Interface Box message prompt indicates that communications between the
Interface Box and computer have been established. Before proceeding with
troubleshooting, attempt to establish communications again by clicking the
Connect button on SEATERM’s toolbar or hitting the Enter key several times.
Cause/Solution 1 : The I/O cable connection may be loose. Check the cabling
between the Interface Box and computer for a loose connection.
Cause/Solution 2 : The instrument type and/or its communication settings may
not have been entered correctly in SEATERM. Select SBE 45 in the Configure
menu and verify the settings in the Configuration Options dialog box. 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 Interface Box permits connection to the DB-9P input
connectors used on standard RS-232 interfaces.
Problem 2: Unable to Communicate with SBE 45 through Interface Box
In SEATERM, while communicating with the Interface Box, send
Connect45 .
The following message should appear:
connected to SBE 45 . . .
This indicates that communications between the Interface Box and SBE 45
have been established. If this messages does not appear:
Cause/Solution 1 : The cable connection may be loose. Check the cabling
between the SBE 45 and Interface Box for a loose connection.
Cause/Solution 2 : The cable between the SBE 45 and Interface Box may not
be the correct one. Verify that the cable is the correct one.
Cause/Solution 3 : The instrument type and/or its communication settings may
not have been entered correctly in SEATERM. Select SBE 45 in the Configure
menu and verify the settings in the Configuration Options dialog box. The
settings should match those on the instrument Configuration Sheet.
Cause/Solution 4 : The baud rate for communication between the SBE 45 and
Interface Box may not match. The SBE 45’s baud rate (set with Baud= when
directly communicating with the SBE 45) must be the same as the baud rate
set in the Interface Box with
45Baud= .
Cause/Solution 5 : The SBE 45 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 45.
•
Increase the Interface Box baud rate using PCBaud= . Or
•
Connect the SBE 45 directly to the computer and decrease its baud rate
using
Baud= . Then, with the Interface Box connected to the computer,
use 45Baud= to match the baud set in the SBE 45.
