Speed log
Provided that a speed log sensor is interfaced to the EK80, the vessel's current speed can
be presented in the user interface. A speed log is normally not a part of the EK80 delivery.
In most cases a suitable sensor is already installed on the vessel. A global positioning
system (GPS) with a compatible output format can also be used.
The speed log interface requirements are:
• : Standard NMEA 0183 datagram formats
Serial line
•
Ethernet (LAN) line

Course gyro
When a course gyro is connected to the EK80, the vessel's current heading can be
presented in the user interface. A course gyro is not a part of the EK80 delivery.
Note
Without the input from a course gyro, the EK80 will not be able to present correct
navigational information.
In most cases a suitable course gyro is already installed on the vessel. A global
positioning system (GPS) with a compatible output format can also be used.
The course gyro interface requirements are:
• : Standard NMEA 0183 datagram formats
Serial line
•
Ethernet (LAN) line

Motion Reference Unit (MRU)
For improved operational accuracy we suggest that you connect a motion reference
unit (MRU) to the EK80.
Without the input from a motion reference sensor, the EK80 will not be able to
compensate for the vessel movements. This lack of compensation will prevent the EK80
from providing correct echo information.
