Supported datagram formats for heading and gyro information
The heading sensor provides the ES80 with the vessel’s current heading. When enabled, the
vessel's current heading is shown on the top bar.
The ES80 supports the following datagram formats for vessel heading and/or
gyro information.
•
NMEA HDT
The NMEA HDT datagram provides the true vessel heading. The information is normally
provided by a course gyro.
•
NMEA HDM
The NMEA HDM datagram provides vessel heading in degrees magnetic. The datagram
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.
•
NMEA THS
The NMEA THS datagram provides the true vessel heading. The datagram includes a
mode indicator field providing critical safety-related information about the heading data.
The THS datagram replaces the deprecated HDT.

Supported datagram formats for trawl information
The data communication from an external trawl system is based on proprietary data formats.
The ES80 supports the following datagram formats from a trawl system:
•
Simrad DBS
Simrad DBS is a proprietary datagram format created by Kongsberg Maritime to provide
the current depth of the trawl sensor.
•
Simrad HFB
Simrad HFB is a proprietary datagram format created by Kongsberg Maritime. It
provides the vertical distance (height) from the headrope to the footrope, and from the
headrope to the bottom. The heights are measured by an ITI TrawlEye or a height sensor.
If you use two height sensors, the information from the second sensor is provided in the
Simrad HB2 datagram.
