Using AIS

10.2 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 unit or a full transceiver (a unit that sends and
receives).
• A VHF antenna - this is usually supplied with the AIS system.
• A GPS - to provide position data.
• A Compass - although not essential, will improve speed
calculations.
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 transducer data
box.
You will now need to specify the 38,400 baud setting (Menu >
System Setup > System Integration > NMEA Port Setting) for the
NMEA port that communicates with the AIS transceiver or receiver.
