13.2 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.
13.3 AIS context menu
The AIS function includes a context menu which provides AIS target
information and menu items.
The AIS context menu can be accessed by:
• Highlighting an AIS target using the Joystick and pressing the
Ok button, or

multifunction displays only.
The context menu provides the following AIS target data:
