NMEA HDM
The NMEA HDM datagram provides vessel heading in degrees magnetic. The
datagram format is no longer recommended for use in new designs. It is often
replaced by the NMEA HDG telegram.
•
NMEA HDG
The NMEA HDG datagram provides heading from a magnetic sensor. If this reading
is corrected for deviation it produces the magnetic heading. If it is offset by variation,
it provides the true heading.
Supported datagram formats for motion information
The EA640 supports the following datagram formats from a motion sensor.
•
Kongsberg EM Attitude 3000
The EM Attitude 3000 is a proprietary datagram format created by Kongsberg
Maritime for use with digital motion sensors.
•
Simrad TSS1
Simrad Sounder/TSS1 is a proprietary datagram format created by Kongsberg
Maritime for heave, roll and pitch compensation. When you select this protocol, the
number of sensor variables is fixed, and there is no token associated with it.
Supported datagram formats for annotation data
The EA640 supports the following datagram format for annotations.
•
Simrad ATS datagram format
Simrad ATS is a proprietary datagram format created by Kongsberg Maritime. It
allows you to import annotations from external devices.
Supported datagram formats for depth information
The EA640 supports the following datagram formats for depth output.
•
NMEA DBS
The NMEA DBS datagram provides the current depth from the surface. The datagram
is no longer recommended for use in new designs. It is frequently replaced by the
NMEA DPT datagram.
•
NMEA DBT
The NMEA DBT datagram provides the current depth under the transducer. In new
designs, this datagram is frequently used to replace the DBK and DBS datagrams.
•
NMEA DPT
The NMEA DPT datagram provides the water depth relative to the transducer, and
the offset of the measuring transducer.
