Simrad AI80 User Manual page 15

The Mobile Unit broadcasts the vessel's position, speed and course
as well as static and voyage related information.
The unit incorporates two VHF receivers, one VHF transmitter, one
DSC receiver, one GPS receiver and a processor. The internal GPS
receiver is used for time synchronisation and for back-up position
sensor.
The MKD unit provides a simple user interface to the Mobile Unit
with basic presentation of configuration data and position data in a
4x20 character display.
Buttons are used for selecting display pages, for input of data to the
system, and for writing text messages transmitted to other vessels or
shore based AIS stations.
A Pilot Plug is included in the AI80 system and is located at the rear
of the MKD. The plug enables the pilot to connect a Personal Pilot
Unit (PPU) to the AIS system.
The supplied L1 GPS antenna is delivered with a universal antenna
mounting kit and an adapter cable with N connectors for connection
to a customer supplied GPS antenna cable, e.g. RG-214.
The system may also be delivered with an optional, external MKD.
This MKD provides either a 25x15 character display or a graphical
view.
Note !
A customer supplied VHF antenna must be included in the AI80
system. A qualified antenna must cover marine band (156 MHz - 164
MHz), have omni-directional vertical polarization and provide 2 to 5
dB gain.
