5.3 Northstar 8000i / Simrad GB 40 using a NMEA 0183 heading
sensor
The diagram below shows how to connect the radar to a Northstar 8000i or Simrad GB40
system for vessels that use a NEMA 0183 heading sensor.
For key
information
(page 39)
The compass must be NMEA compliant and configured as follows:
• 10 Hz update rate
• 4800 baud
The compass must be able to supply the NMEA 0183 HDT, HDM, and HDG heading sentences
(all other sentence types will be ignored).
The NMEA compass must be directly connected to the 8000i / GB40 through the Utility port and
the radar processor through the NMEA/COMMS port.
Compass data is appended to the radar data by the radar processor and then broadcast over
the network to the 8000i or GB40 displays and other devices. This enables more precise radar
chart overlay and target tracking (MARPA).
The NMEA compass cable is not supplied but the pinout of the NMEA/COMMS port is shown for
