Send
QS
to put the CTD in quiescent (sleep) state (not applicable to
SBE 49).
13.
If using the SBE 33 with a NMEA device:
Type
@
to return to the setup
menu. Type
3
and press the Enter key to switch to mode 3. 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 = 3. Transmit Lat/Lon only
enter 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11 followed by Enter,
or press @ to exit the set up menu

Go to
Step 14
to verify proper operation if the SBE 33 is used with a
NMEA navigation (position) device.
Go to
Step 15
to verify proper operation if the SBE 33 is used with
both
a
NMEA navigation (position) device
and
a NMEA depth device.
14.
If using the SBE 33 with a NMEA navigation (position) device:
Type
@
to exit the setup menu. You should begin seeing NMEA data
display in Seaterm. Each time NMEA data is received, the yellow
NMEA
Transmit
LED on the SBE 33 should flash.
If NMEA data does not appear, verify that the SBE 33 is connected to
the NMEA device and that the proper cable is used.
See
Section 7: Troubleshooting
for additional instructions if needed.
15.
If using the SBE 33 with a NMEA navigation (position) device
and
a
NMEA depth device:
While in mode 3, type
10
and press the Enter key
to switch to mode 10. Mode 10 is a diagnostic mode that passes all raw
NMEA characters received to the screen. The response indicates:
the current mode = 3. Transmit Lat/Lon/Depth only
diagnostic level 1 enabled.
Type
@
to exit the menu. You should begin seeing
raw
NMEA messages
display in Seaterm. Typical RMC and DPT messages are:
$LGRMC,123113.21,A,3625.12,N,12121.34,W,1.2,4.5,231294,1.2,a*45<CR><LF>
$SDDPT,0005.4,0000.0*56<CR><LF>
See
Appendix I: NMEA Device Message and Data Formats
for a description
of all the NMEA messages the SBE 33 can decode.
If NMEA data does not appear, verify that the SBE 33 is connected to
the NMEA device and that the proper cable is used.
See
Section 7: Troubleshooting
for additional instructions if needed.
16.
Turn off power to the SBE 33.
Note:
NMEA depth data will not appear in
Mode 3. If using both a NMEA
navigation device and a NMEA
depth device, go to Step 15.
Note:
To exit diagnostic mode, turn off
power to the SBE 33.
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
