1System description

1.1 General

Congratulations on the purchase of your new Simrad

AP28 autopilot system and thank you for selecting what

we feel is the most advanced autopilot system available

on the market today.

The Simrad AP28 autopilot represents yet another step

forward in autopilot technology providing leisure boats

between 30 and 50 feet with a host of features.

The autopilot system can be expanded and enhanced

with a selection of options and accessories.

The brain in the AP28 autopilot system is the single

"intelligent" autopilot computer that communicates on

the proprietary SimNet data and control network to

establish a reliable digital communication and power

distribution between the units in the autopilot system as

well as other Simrad products.

A compact autopilot control for panel,

bulkhead or bracket mounting. A multifunction

LCD display with two-color backlighting

presents readout of autopilot and navigation

data, tactile keys, dedicated mode keys and

rotary course knob provide simple and precise

operation. It has two SimNet connectors for

system interconnection and control, expansion

and data sharing with other Simrad products.

A NMEA2000 Adapter Cable is available for

interface through a SimNet port.

System description | 9

Multiple control units can be added to the system by

daisy-chaining or drop cable to the SimNet network.

1.4 Autopilot Computer

The autopilot computer is the main unit in the AP28

autopilot system. It contains the steering computer and

drive electronics for the drive unit motor and clutch and

provides interface to other system components. Two

models, AC12 and AC42 are available.

1.5 Rudder Feedback unit

RF25 Rudder Feedback Unit

The RF25 is designed for connection to the SimNet

network. It comes with transmission link and 5 m (16

feet) of SimNet cable with connector.

The RF25 provides rudder angle output to a separate

rudder angle indicator also when the autopilot is

switched off.

RF300 Rudder Feedback Unit (optional)

The RF300 is designed for connection to the autopilot

computer. It comes with transmission link and 10 m (33

feet) of cable. RF300 has a different signal format and

does not offer the same accuracy as RF25.

With an RF300 as rudder feedback there is no output to

separate rudder angle indicators when the autopilot is

off.

1.6 Heading Sensors

RC42 Rate Compass

RC42 is a fluxgate compass with an integrated rate of

turn sensor. It provides a significant improvement to the

dynamic performance of both the autopilot and a

stabilized radar display. A 5 m (16 feet) SimNet cable

with connector is attached.

FC40 Fluxgate Compass (optional)

This is a compact magnetic heading sensor using a

floating ringcore in a fluxgate coil. A 5 m (16 feet)

SimNet cable with connector is attached. The dynamic

performance is second to the RC42.

1.7 Optional equipment

See page 115.

1.8 Software record

When the system is switched on, a status display shows

the software version for the control unit. See page 14.
