Problem 6: Changing SBE 45 and/or SBE 38 Baud Rate without Cables for
Direct Connection
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 and
baud rate between the Interface Box and the SBE 38. If you need to change the
baud rate in the SBE 45 and/or SBE 38 for compatibility with the Interface
Box, this procedure allows you to change the baud rate while the instrument is
communicating through the Interface Box. The procedure is written assuming
that the SBE 45 and SBE 38 are set to 9600 baud, but that you want the
computer to communicate with the Interface Box at 9600 baud.
In SEATERM:
1.
Establish communications with the Interface Box, as described in Steps 1
through 4 in
Communications Test and Setup in Section 3: Setting Up
System .
2.
With the Interface Box in Normal mode, send PCBaud=19200
to change the baud rate between the Interface Box and the computer
to 19200.
3. In the Configure menu, select the SBE 45 and set the baud rate to 19200.
Turn power to the Interface Box off, and then on again. The Interface Box
is now communicating at 19200 baud.
4. To modify the SBE 45 baud rate:
A.
Send 45Baud=9600 to set the baud rate in the Interface Box for
communication with the SBE 45 to 9600.
B. Send Connect45 to communicate with the SBE 45.
C. If the SBE 45 is sampling data, stop sampling by sending Stop (you
may need to send the command several times).
D. Send Baud=4800 to set the SBE 45 baud rate to 4800.
E. Type @ to return to Normal mode for communication with the
Interface Box.
F. Send 45Baud=4800 to set the baud rate in the Interface Box for
communication with the SBE 45 to 4800.
5.
To modify the SBE 38 baud rate:
A.
Send 38Baud=9600 to set the baud rate in the Interface Box for
communication with the SBE 38 to 9600.
B. Send Connect38 to communicate with the SBE 38.
C. If the SBE 38 is sampling data, stop sampling by sending Stop (you
may need to send the command several times).
D. Send Baud=4800 to set the SBE 38 baud rate to 4800.
E. Type @ to return to Normal mode for communication with the
Interface Box.
F. Send 38Baud=4800 to set the baud rate in the Interface Box for
communication with the SBE 45 to 4800.
6.
Send PCBaud=9600 to change the baud rate between the Interface Box
and the computer to 9600.
7.
In the Configure menu, select the SBE 45 and set the baud rate to 9600.
Turn power to the Interface Box off, and then on again. The Interface Box
is now communicating with the computer at 9600 baud. If the SBE 45 and
SBE 38 are set up to begin sampling when power is applied, data will
appear.
Note:
If you have a cable for direct
connection of the SBE 45 to the
computer and the SBE 38 to the
computer, see
Setting Up
Instruments in Section 3: Setting Up
System to change the baud rates.
