9.2 How to function AIS on your MT-550
Your
MT-550
has built-in dual channel AIS receiver (only receiver, not transponder),
which monitors both AIS1 and AIS2 channels and receives AIS data from vessels
fitted with class A or B transponder around your vessel. No extra VHF antenna is
needed. Received AIS data is decoded and automatically transferred to a
connected AIS capable GPS chart plotter via NMEA interface.
NOTE
Your
MT-550
doesn’t display received AIS information on its LCD. To see received
AIS information, you need to connect an AIS capable GPS chart plotter which can
accept NMEA VDM sentence at 38400 bps.
For the connection to AIS capable GPS chart plotter, please see the
4.4 NMEA
Cable
topic of
4. INSTALLATION
