Supported datagram formats for external depth input
The EK80 can receive depth information from en external echo sounder.
The EK80 supports the following datagram format for depth information from an echo
sounder:
•
NMEA DPT
The NMEA DPT datagram provides the water depth relative to the transducer, and
the offset of the measuring transducer.

Supported datagram formats for position information
Accurate and reliable information from navigation systems are useful for the EK80
operation. When enabled, the vessel's current geographical position is shown on the
top bar.
The EK80 supports the following datagram formats for position
information.
•
NMEA GLL
The NMEA GLL datagram transfers the latitude and longitude of vessel position, the
time of the position fix and the current status from a global positioning system (GPS).
•
NMEA GGA
The NMEA GGA datagram transfers time-, position- and fix-related data from a
global positioning system (GPS).
•
NMEA GGK
The NMEA GGK datagram is used to decode the PTNL, Time, Position, Type and
DOP (Dilution of Precision) string of the NMEA 0183 output.
•
PTNL GGK
PTNL GGK is a proprietary datagram from Trimble ( https://www.trimble.com ). It is
longer than the standard NMEA GGK datagram. The PTNL GGK datagram is used to
decode the time, position, type and dilution of precision of the current position.
•
NMEA RMC
The NMEA RMC datagram transfers the time, date, position, course and speed data
from a global navigation satellite system (GNSS) receiver.
•
NMEA VTG
The NMEA VTG datagram contains the actual course and speed relative to the ground.
