Appendix E: Connecting a Raymarine
Heading Sensor
The performance of MARPA and radar/chart overlay on the displays is
dependent on the quality of your heading sensor.
Raymarine recommend that, for optimum MARPA and radar/chart overlay
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 8-15 on page 26
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 on each
of your displays that will be used for MARPA and radar/chart overlay.
• For each display, in the System Set Up Menu set Bridge NMEA Heading
OFF (see Bridge NMEA Heading on page 7-9).
