7.2. Configuration Manager Options
In order for this component to work properly, NMEA compatible depth, heading, GPS, and speed sensors
must be connected to the SonaSoft™ user interface computer. These sensors include: echo sounder, GPS,
gyro-compass, Doppler speed log, paddle wheel transducer, etc. More information on NMEA connections
can be found in the chapter entitled Section 4.2, “Connecting NMEA Devices”. Under the the Configuration
Manager's NMEA Settings menu, the user can specify the type of NMEA message to use.
For echo sounder depth, the user can select from the following NMEA messages:
• DBT: Depth below transducer.
• DPT: Depth below the transducer with reference to keel or surface.
For vessel true heading, the user can select from the following NMEA messages:
• HDG: Heading, deviation, and variation.
• HDT: Heading true.
• VHW: Water speed and heading.
For vessel position, the user can select from the following NMEA messages:
• GGA: Global positioning system fix data.
• GLL: Geographic latitude and longitude.
• RMC: Recommended minimum specific GNSS data.
For vessel speed over ground, the user can select from the following NMEA messages:
• RMC: Recommended minimum specific GNSS data.
• VTG: Course over ground and ground speed.
