You can select from 48 different “Talker ID’s” and 78 different sentence
“Formatters”. You must also specify the correct data field to display by count-
ing the number of commas. For example, a typical NMEA 0183 depth sen-
tence output by many depth sounders is the $SDDBT sentence shown here:
$SDDBT,015.7,f,004.8,M,002.6,F*0D
The first two characters after the $ symbol “ SD ” (Sounder Depth) is called the
Talker ID and the next three characters “ DBT ” (Depth Below Transducer) is
called the Sentence Formatter. The complete list of NMEA 0183 Talker ID
codes and Sentence Formatters is shown in Appendix F along with some
limitations of what can and cannot be displayed on the MaxVu110.
In the above sample NMEA sentence the first field “015.7” is located after the
first comma and contains the depth in Feet. The second field “004.8” is located
after the third comma and contains the depth in Meters. By selecting the appro-
priate field and counting commas we can display depth in Feet, Meters or Fath-
oms on the MaxVu110.
