INSTALLING THE ACU
NOTE:
Determine the type of gyrocompass OUTPUT on the ship, assure that the
GYRO TYPE parameter is set correctly (refer to the operation section of this menu).
The heading in most cases will be 000.0 and you will have to enter the initial value of
the ships current value whenever you turn on the ACU.
The ship’s heading is not an input requirement when your system is connected to a
1:1 Synchro or NMEA 0183 Heading Gyrocompass output.
Ship Gyro Connection
For satellite tracking, you must connect a ship’s Gyro to the antenna system
through the gyro interface on the rear of the ACU. If the ship’s gyrocompass
output is other than NMEA 0183 and Synchro, a separate purchase of a gyro
converter is required.
