Interface specifications - Processing Unit - KMall format
The EM 2040 MKII system will interface with peripheral systems and sensors using
standard and/or proprietary datagram formats. This is a description of available datagram
formats for EM multibeams using the KMall format.
Supported datagram formats for position information
The EM 2040 MKII supports the following datagram format for position information.
•
NMEA GGA
The NMEA GGA datagram transfers time-, position- and fix-related data from a
global positioning system (GPS).
•
PTNL GGK
This third party datagram format is used to transfer latitude and longitude of vessel
position, time of position fix and status from a global positioning system (GPS).
Supported datagram formats for external clock
The EM 2040 MKII supports the following datagram format from an external clock.
•
NMEA ZDA
The NMEA ZDA datagram contains the universal time code (UTC), day, month,
year and local time zone.
Supported datagram formats for depth information
The EM 2040 MKII supports the following datagram formats for depth information
from an echo sounder:
These datagram formats are received using a serial or Ethernet (LAN) line.
•
NMEA DPT
The NMEA DPT datagram provides the water depth relative to the transducer, and
the offset of the measuring transducer.
•
NMEA XDR
The NMEA XDR datagram provides measurement data from transducers that measure
physical quantities such as temperature, force, pressure, frequency, angular or linear
displacement, etc.
In this context the XDR datagram is used as XDR-P to provide the depth from
waterline.
•
Digiquartz pressure sensor
This datagram from Digiquartz contains depth from waterline and pressure.
