V110 – Marine Satellite Communication System
Connecting the System to a Ship’s Gyro
For satellite tracking, you must connect a ship’s Gyro to the antenna
system through the gyro interface on the rear of the ACU. Intellian’s ACU
supports three different gyro types, Step-by Step (SBS), Synchro and
NMEA 0183.
SBS/ Synchro/ NMEA 0183 Gyro Compass Interface Cable (Customer
Furnished)
Type: Multi-conductor (4 conductors for SBS, 5 conductors for Synchro,
and 2 conductors for NMEA 0183).

WARNING: 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).Heading in most cases will
be 000.0 and you will have to enter the initial value of ships
current value whenever you turn on the ACU. The ship’s
heading is not required to input when your system is
connected to a 1:1 Synchro or NMEA 0183 Heading
Gyrocompass output.
