1System description

1.1 General

The autopilot computer is the main unit in the AP24 and

AP28 autopilot systems. It contains the steering

computer and electronics for the drive unit motor and

clutch and provides interface to other system

components. Two models, AC12 (8/16 A motor current)

and AC42 (30/50 A motor current) are available.

It 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.

SimNet provides high speed data transfer and control of

Simrad products integrated in a total steering and

navigation system.

1.2 How to use this manual

This manual is intended as a reference guide for installing

and maintaining the Simrad AC12 and AC42 autopilot

computers and other components in an autopilot system.

Please take time to read this manual to get a thorough

understanding of the system components and their

relationship to a complete autopilot system.

Other documentation material that is provided with your

system includes an operator manual which includes the

setup instructions for the system, a control unit

installation guide and a warranty card. The warranty card

must be filled out by the authorized dealer that

performed the installation.

1.3 Software record

Control units

When the system is switched on, a status display shows

the serial number and software version for the control

unit.

The shown readout is only an example!

Autopilot computers

Serial number and software version for autopilot

computers and other SimNet sources can be found under

the control unit User setup menu. Refer to Manual source

selection in the autopilot operator manual.

2Installation

An autopilot system includes several units that need to

be mounted in different locations on the boat, and also

need to interface with at least three different systems on

the boat:

•The boat's steering system

•The boats electrical system (input power)

•Other equipment on board (SimNet interfacing)

In addition, the advanced capabilities of the system

require the installer to perform a series of settings and

tests to verify proper operation of the system, refer to

the check list below.

2.1 Installation checklist

1. Determine the system configuration you are

installing (Page 8)

2. Perform the hardware installation (Page 11)

3. Connect SimNet devices to SimNet (page 26)

4. Perform Set-up (refer to Operator manual)

5. Test Autopilot Operation at Sea (refer to Sea Trial

instructions in the Operator manual)

2.2 Unpacking and handling

Care should be taken when unpacking and handling the

equipment. A visual inspection should be made to see

that the equipment has not been damaged during

shipment and that all components and parts are present

according to the packing list.

An autopilot system will include:

•Control unit (AP24 or AP28) with accessories

−Installation accessories

−Operator manual

8 | Installation

•Autopilot computer (AC12 or AC42) with accessories

−SimNet cable 5,5 m (18’)

−Installation accessories

−AC12/AC42 Installation Manual

•Compass (FC40 or RC42) with 5,5 m (18') SimNet

cable attached

•Feedback unit (RF300 or RF25) with transmission rod

and cable attached.

•Appropriate drive unit for the installation (unless the

autopilot is going to operate an existing drive unit or

solenoids).

•Optional equipment that may have been ordered for

the installation.

2.3 Determine system configuration

It is important to become familiar with the configuration

of the system prior to beginning the installation. An

autopilot basic single station system is shown in Figure

2-1 and a system layout with options is shown in Figure

2-2

Plan your cabling and configure the SimNet network in

accordance with chapter 2.15 on page 26. Pay particular

attention to the autopilot computer/drive unit

combinations.

As most of the units are communicating on a common

network (SimNet) with identical connectors, the

installation is simple. Try to mount the units within the

standard cable length supplied with each unit. SimNet

cables are available from your distributor (see page 33)

for connection to other SimNet devices and cable

extension.

1On boats powered by outboards or stern drives it

may be difficult to install a rudder feedback unit

(Refer to RF300, RF25 or LF3000 in this manual).

Use of the Virtual Rudder Feedback, VRF™,

algorithms in the software may then be preferred

as this requires no installation of a rudder feedback

unit. The VRF can be used on boats up to 40 ft.

2The VRF technology requires a Simrad rate

compass (RC42) for heading information to the

autopilot system.
