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 10" CRT display.
• If you require heading data on the SeaTalk system when the 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" CRT display).
Set
Bridge NMEA Heading
OFF in the CRT display System Set Up menu.
• If you do not fit a NMEA/SeaTalk interface box, set
Bridge NMEA Heading
ON in the CRT display System Set Up menu.
The 10" CRT display provides the heading data to the SeaTalk system. Note
that when the 10" CRT 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.
