NMEA 0183
The units has two NMEA 0183 ports, which are connected via two discrete cables. Each cable
is dedicated to one of the two internal processors.
Ú
Note: AIS data supplied via NMEA 0183 is not internally bridged, and must be connected
to both NMEA 0183 ports if required on both screens. AIS data supplied via NMEA 2000 is
available to both processors.
