Raytheon ST80
ST80 System (without Course Computer)
If you have a Raytheon ST80 system 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 NMEA input of the display.
• If you require heading data on the SeaTalk system when the 10.4" LCD/
10" CRT display is switched OFF, you must fit a NMEA/SeaTalk interface
box (part number Z290 or E85001). The NMEA heading data is connected
to the interface box (in addition to the 10.4" LCD/10" CRT display).
Set Bridge NMEA Heading OFF in the display System Set Up menu.
• If you do not fit a NMEA/SeaTalk interface box, set Bridge NMEA Head-
ing ON in the display System Set Up menu.
The 10.4" LCD/10" CRT display provides the heading data to the SeaTalk
system. Note that when the display is switched OFF, heading data is not
available on the SeaTalk system.
• Manually calibrate the compass in NMEA mode as described in the section
Calibrating the ST80 Active Compass.
