Nmea - NorthStar NS3300 AutoPilot Installation Manual

1-2-3 NMEA

NMEA is an industry standard, but is not as flexible as NavBus as it requires dedicated connections between
instruments. The PILOT 3300 system has one NMEA input port and one port that can be configured to be an
input or an output (See PILOT 3300 Reference manual).
PILOT 3300 system NMEA inputs
GPS: The PILOT 3300 system can receive NMEA GPS data from a compatible GPS or chartplotter, such as
Northstar's 6000i series chartplotter:
WIND: The PILOT 3300 system can receive NMEA wind data from a compatible wind instrument:
SPEED: The PILOT 3300 system can receive NMEA speed data from a compatible paddlewheel or GPS
instrument:
Note: If the PILOT 3300 system is connected to a Northstar series wind or speed instrument using NavBus, then the PILOT
3300 system will automatically receive and use the wind or speed data, and the NMEA connection need not be wired.
PILOT 3300 system NMEA outputs
The NMEA 2 port can be configured to be an input or to be output:
(see NMEA mode in the Setup > Comms menu, See PILOT 3300 Reference manual).
Reference Manual
XTE (from APA, APB or XTE sentences) is required for the PILOT 3300 system to use GPS mode
BRG (from APA sentences) and BOD (from APA or APB sentences) are optional and improve performance
COG (from VTG sentences) is optional and can be displayed.
True or apparent wind direction (from MWV sentences) is required for the PILOT 3300 system to
use Wind mode.
SOG (from VTG sentences) is optional and improves performance.
either heading (HDG & HDT) and rudder angle (RSA) at once per second
or heading (HDG) at ten times per second
