Interface specifications - Processing Unit - KMall format
The EM 712 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 KMall format.
Supported datagram formats for position information
The EM 712 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 712 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 motion information
The EM 712 supports the following datagram format 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. It holds roll, pitch, heave and heading
information. The datagram contains a 10-byte message.
Supported datagram formats for motion information including velocity
The EM 712 supports the following datagram formats from a motion sensor.
•
KM Binary
KM Binary is a general datagram format defined by Kongsberg Maritime. This format
has very high resolution on timing and sensor parameters.
•
Seapath Binary 11
This is a proprietary format created by Kongsberg Seatex ( http://www.km.kongs-
berg.com/seatex ) for position, attitude and velocity data from the Seapath sensor.
Seapath Binary 11 is an old format with low resolution that Kongsberg does not
recommend.
•
Seapath Binary 23
This is a proprietary format created by Kongsberg Seatex ( http://www.km.kongs-
berg.com/seatex ) for position, attitude and velocity data from the Seapath sensor.
