1.3 Course Computer
The course computer, available in both 12V or 24V versions, houses a
microprocessor, drive unit electronic control circuitry and power amplifier.
It is the central distribution point for the autopilot, electrical wiring and
ship’s power connection point.
The course computer also has NMEA input and outputs to allow operation
with other manufacturer's equipment.
The unit is only splash proof and must, therefore, be installed in a dry,
protected location.
Type 100 is used for Type 1 and Type CR 12V drives. Type 300 is used
with Type 2 and Type 3 drives.

1.4 Fluxgate Compass
The fluxgate compass contains a gimbal mechanism that permits
accurate readings with pitch and roll movements up to +/- 35 degrees.
The compass is designed for below deck, bulkhead mounting and
connects directly to the course computer.
On steel decked vessels the compass can be mounted above deck,
however, autopilot performance may be affected due to the increased
motion.
