Type
@
to access the setup menu. The display looks like this:
SBE 33/36 Deck Unit set up menu:
Modes:
1. Echo characters to and from the instrument
2. Add Lat/Lon to the real-time HEX data from the instrument
3. Transmit Lat/Lon only
Options:
4. Add NMEA Depth to the real-time HEX/Lat/Lon data
5. Do not add NMEA Depth to the real-time HEX/Lat/Lon data
6. Add PAR to the real-time HEX data
7. Do not add PAR to the real-time HEX data
Communications:
8. Change communication settings and start mode
9. Display communication settings and start mode
Diagnostics:
10. enable diagnostic level 1
11. enable diagnostic level 2
the current mode = 1. Echo characters to and from the
instrument
enter 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11 followed by Enter,
or press @ to exit the set up menu
selection =
5.
To view the current communication and start mode settings, type
9
and
press the Enter key. The display looks like this:
PC baud rate = 9600
CTD baud rate = 4800
8 data bits, no parity
NMEA baud rate = 4800
NMEA messages decoded = GGA, GLL, RMA, RMC, TRF, DBT, DPT
Surface PAR disabled
NMEA depth disabled
start mode = Echo characters to and from the instrument
If the
CTD baud rate
does not match the baud rate set in your CTD, the
computer will not be able to communicate with the CTD through the
SBE 33. Step 6 provides instructions for changing the CTD baud rate in
the SBE 33 to match your CTD.
6.
To change the current communication settings and/or start mode settings,
type
8
and press the Enter key. The display looks like this:
PC baud rate = X, new value =
(type desired value, press Enter)
CTD baud rate = X, new value =
(type desired value. press Enter)
parity = X, new value = even parity or no parity [e/n]
(type
e
or
n,
press Enter)
NMEA baud rate = X, new value =
(type desired value, press Enter)
Start mode = X, new value = echo or add Lat/Lon [e/a]
(type
e
or
a,
press Enter)
The display then shows your new selections. Type
@
to return to the
setup menu.
7.
Type
1
and press the Enter key to put the SBE 33 in
mode 1
(
echo
characters to and from the instrument
),
which is the mode required for
communicating with the CTD (i.e., sending CTD setup commands)
.
8.
Type
@
to exit the setup menu.
9.
Click Connect on the Toolbar (or press the Enter key several times) to
establish communication with the CTD (through the SBE 33).
The system should respond with an S> prompt.
10.
Click Status on the Toolbar to send
DS
and display CTD status. If the
status displays and is correct, the system is connected properly.
11.
If desired, send setup commands to the CTD.
Notes:
CTD baud rate must be less
than or equal to PC baud rate.
NMEA baud rate is 4800 or
9600.
Parity selection also affects the
communication data bits:
even parity = 7 data bits,
no parity = 8 data bits.
Changing
PC baud rate
or
parity
disrupts communications,
because they must match the
settings in Seaterm’s Configure
menu. See
Changing
Communication Settings
between SBE 33 and Computer
below for changing settings and
reestablishing communications.
If NMEA depth is enabled
(using a NMEA depth device as
well as a NMEA position
device) and/or Surface PAR is
enabled, the query for Start
Mode changes to include
NMEA Depth and/or PAR, as
applicable:
new value = echo or add
Lat/Lon/
Depth/PAR
Note:
The communication and start mode
settings were also shown in the status
message that appeared when you
turned on power to the SBE 33; see
Step 3 above.
Note:
If NMEA depth is enabled (using a
NMEA depth device as well as a
NMEA position device) and/or Surface
PAR is enabled, the description for
mode 2 changes to include NMEA
Depth and/or PAR, as applicable:
2. Add Lat/Lon/
Depth/PAR
to the
real-time HEX data from the
instrument
