Sensor

The performance of MARPA and radar/chart overlay on the 

hsb

 displays is 

dependent on the quality of your heading sensor.

Raymarine recommend that, for optimum MARPA and radar/chart overlay 
operation, you use Raymarine Rate Gyro Compass 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 Rate Gyro Compass 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.

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 

hsb

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 7-8).
