Note: Incoming safety messages cannot be displayed while thesimulator is switched on.10.2 AIS prerequisitesYou must have suitable AIS hardware connected to yourmultifunction 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 sendsand receives).• A VHF antenna - this is usually supplied with the AIS system.• A GPS - to provide position data.• The AIS layer enabled in the chart or radar application, asappropriate.Note: A receiver will allow you to receive data about othervessels in your area but will not allow other vessels to ‘see’ you.A full transceiver transmits and receives AIS data, and thereforeallows you to receive data about other vessels. It also enablesother AIS-equipped vessels to see and receive information aboutyour vessel. This could include position, course, speed and rateof turn data.When the AIS unit is connected to your multifunction display, thestatus of the unit is indicated by an AIS icon in the transducer databox.You can connect an AIS unit to your multifunction display usingNMEA0183 or SeaTalkng, depending on the AIS unit. If connectingusing NMEA0183, you will now need to specify the 38,400 baudsetting (Menu > System Setup > System Integration > NMEAPort Setting) for the NMEA port that communicates with the AIStransceiver or receiver.Using AIS 149
