Appendix E: Connecting A Raytheon ST80 Active Compass for MARPA

Autopilot 4000/5000

If you have a Raytheon Autopilot 4000 or 5000 (with compass) and a
Raytheon active compass, we recommend that you configure your system as
follows:
• Ensure the active compass is re-wired to provide heading data on NMEA.
• Provide 12V power to the active compass.
• Connect the active compass to the NMEA input of your display.
• Enable Bridge NMEA Heading in the display System Set Up menu.
• Calibrate the autopilot's compass (as described in the autopilot Owner's
Handbook) with the10.4" LCD/10" CRT display switched OFF.
• Manually calibrate the NMEA compass with the 10.4" LCD/10" CRT dis-
play switched ON as described in the section Calibrating the ST80 Active
Compass.
Note that both compasses are linearised and aligned. When the radar is ON,
the SeaTalk heading from the HSB Series display takes precedence in the
autopilot; when the HSB Series display is switched off, the autopilot uses the
locally connected compass. If the two compasses are mismatched, the
autopilot heading will change when the radar is switched on/off
