Operations And Maintenance Manual
3.3.1.3 NMEA Depth (dpt)
Sample data strings
$SDDPT, 3.4, 0.0 $SDDPT, 6.4, 0.0 $SDDPT, 6.4, 0.2
Industry standard NMEA 0183 string. Water depth relative to the transducer and offset of the measuring
transducer.
Format described below.
$ S D D P T , x x x x . x, y y . y <CR><LF>
Where x x x x . x = Depth from transducer in meters y y . y = Offset from transducer, meters
3.3.1.4 Configure Events
This menu is used to configure eventing and
annotation. Events may be generated by using the
toolbar button, or the corresponding menu option
“Insert Event Mark” under the
Edit menu. An
event is a vertical marker which appears on both
the screen and printer. A number of real-time
parameters may be included with the events as
derived by the user. These parameters are shown
in the previous picture under “Annotate Event
Mark With...”. In addition, the user may choose
between 3 Eventing trigger methods including,
Manual , Periodic , or External . When in “ Manual
Eventing ”, event marks are inserted only when
one is requested by the user using one of the
methods described above. “
Periodic Eventing ”
allows the HydroBox software to insert events at a
specific interval, depending on the number of
minutes entered by the user. While in periodic
mode, the user may still insert manual event
marks in addition to the periodic ones. “External
Eventing” has been implemented as means of
allowing third party software, such as HyPack, to
remotely generate Event marks and annotation in
the HydroBox software. It can be configured by
enabling the “External Eventing” option and
setting the communication parameters such as COM Port, Baud Rate, Start Bits, Stop Bits, and Parity to
match the configuration of the third party software. The HydroBox software accepts external
annotation/eventing with the same format that the Bathy-500MF uses. That format is as follows:
(CTRL F) (CTRL A) (Annotation String) (CTRL D) - Generates an event mark containing
the text in the Annotation String
(CTRL F) - Generates an empty event/fix mark
