Gyrocompass Connection
Connecting the System with a Gyrocompass
The ship’s gyrocompass provides true heading input to the antenna which easily
allows the antenna to target and acquire the desired satellite. Intellian always
recommends to connect a gyrocompass to the antenna through the gyrocompass
interface on the ACU. If the ship’s gyrocompass output is other than NMEA 0183
and NMEA 2000, separate purchase of an NMEA converter is required.
Recommended Cable
• NMEA 0183 / NMEA 2000 Gyrocompass Cable (Customer supplied)
• Connector Type: 2 conductors for NMEA 0183, 5 conductors for NMEA 2000
• NMEA heading sentence: xx HDT (4800 Baud, 8, N,1)
If there is no HDT sentence, then use HDM sentence instead.
• NMEA 2000 heading PGN Number = 127250 (Vessel Heading)
