16.2 AIS prerequisites
You must have suitable AIS hardware connected to
your multifunction display to make use of the AIS
functionality.
In order to run AIS, you will need:
• A receive-only AIS unit or a full AIS transceiver (a
unit that sends and receives).
• A VHF antenna.
• A GPS - to provide position data.
• The AIS layer enabled in the chart or radar
application, as appropriate.
Note: A receiver will allow you to receive data
about other vessels in your area but will not allow
other vessels to ‘see’ you. A full transceiver
transmits and receives AIS data, and therefore
allows you to receive data about other vessels. It
also enables other AIS-equipped vessels to see
and receive information about your vessel. This
could include position, course, speed and rate of
turn data.
When the AIS unit is connected to your multifunction
display, the status of the unit is indicated by an AIS
icon in the status bar.
You can connect an AIS unit to your multifunction
display using NMEA0183 or SeaTalk
ng , depending
on the AIS unit. If connecting using NMEA0183,
you will now need to specify the 38,400 baud setting
(
homescreen > Set-up > System Settings > NMEA
Set-up ) for the NMEA input port that communicates
with the AIS transceiver or receiver.
