Appendix E: Connecting a Raymarine
Heading Sensor
The performance of MARPA on the displays is dependent on the quality of
your heading sensor.
Raymarine recommend that, for optimum MARPA operation, you use the
Pathfinder Smart Heading System (which includes the Gyro Plus 2 unit) or a
G-series course computer, connected via NMEA, as your source of heading
data. The G-series course computer uses rate gyro compensation.
This Appendix provides connection details for a Raymarine 150G or 400G
course computer. For information on the Pathfinder Smart Heading System
refer to the handbook supplied with the compass. Figure 8-14 on page 25
shows a typical Pathfinder system with a Rate Gyro Compass system.
If you have a different heading sensor, or require further assistance, please
contact your authorized Raymarine dealer or Raymarine Technical Support.
G-Series Course Computer
Note: A 150 or 400 course computer coupled to the optional GyroPlus unit
will provide heading data of equal quality to the 150G or 400G course com-
puter. The method of connecting to your display is the same.
If you have a Raymarine 150G or 400G course computer we recommend that
you configure your system as follows and illustrated below:
• Connect the course computer NMEA1 output to the NMEA input .
• For each display, in the System Set Up Menu set Bridge NMEA Heading
OFF (see Bridge NMEA Heading on page 7-9).
