NMEA 0183 device connection

The E5000 processor has four NMEA 0183 ports; three for the ECDIS CPU, and one for the NSO
evo2 CPU. Each port supports bi-directional NMEA 0183 traffic. The NMEA 0183 port for the
NSO evo2 CPU may be configured for either NMEA 0183 or touch screen control. Both the
baud rate and sentences output by both CPUs are configurable.

¼ Note:
NMEA 0183 devices communicate at 4800 baud, while NMEA 0183 - HS devices com-
municate at 38,400 baud. Set the serial port baud rate to the same rate as used by the con-
nected equipment.
¼ Note:
AIS is not internally bridged, so it must be connected to one NMEA 0183 port on each
CPU if required on both screens.
