drive unit, and rudder reference
transducer. The basic 

 can be extended to suit

individual requirements. The basic system
is illustrated below in Figure 1.

1.1 

 Course Computer

The course computer houses the
microprocessor, electronic control circuitry
and power amplifier to drive the hydraulic

The course computer is splash proof

only and must be mounted in a dry and
protected position.

 Control Unit

The six button control unit is fully

waterproof and is mounted close to the

mounting, or alternatively can be bracket
mounted if required (bracket mounting kit
Cat. No. 

A second control unit (Cat. No. 2054)

and a hand held control unit (Cat. No.
2056) can be added to the system. The

hand held control unit is fitted with a 6m

 wander lead and plugs into a

bulkhead mounted waterproof socket.
