1System description

1.1 General

The Simrad SG05 is a gateway for interfacing the AP24

and AP28 autopilot systems to Volvo Penta Electronic

Vessel Control (EVC). It contains the steering computer

and provides interface to other system components.

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 SG05 Gateway 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!

SimNet sources

Serial number and software version for 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 connect with at least three different systems on

the boat:

•EVC Autopilot Interface

•The boats electrical system (12V SimNet power)

•Other equipment on board (SimNet/NMEA 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 10)

3. Connect SimNet devices to SimNet (page 15)

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

•SG05 Gateway with accessories

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

attached

•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 with optional station

is shown in Figure 2-1

Plan your cabling and configure the SimNet network in

accordance with chapter 2.9 on page 15.

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 20)

for connection to other SimNet devices and cable

extension.

2.5 SG05 Gateway installation

•The SG05 is bulkhead mounted by the enclosed

screws. The SimNet connectors must be pointing

downwards. Figure 2-3.

•Connect other units according to Figure 2-1. Use only

readymade SimNet cables and accessories. For

SimNet network termination refer to section 2.9 on

page 15.

•Connect 12V SimNet supply. Refer to Figure 2-10 for

correct polarity

•Connect the 1 m pigtail plug into mating connector of

the Volvo Penta Autopilot Interface. Figure 2-4

SG05 has a built in LED that will alternate with 1 Hz when

the unit is up running.

2.6 AP24 and AP28 Control unit

installation

Avoid mounting the control unit(s) where it is easily

exposed to sunlight, as this will shorten the lifetime of

the display.

Do not install the control unit where moisture is

present at the rear. It may cause damage by

entering the breathing hole or by coming into

contact with the electrical connectors.

Panel mounting

The mounting surface must be flat and even to within 0.5

mm.

•Drill the 4 mounting holes and make a panel cut-out

according to supplied template.

•Connect the SimNet cable(s) to the control unit

connector(s)

•To daisy chain units remove the blocking plug with a

pair of pliers.

•Use the supplied 19 mm screws to fasten the control

unit to the panel.

•Apply the front panel corners.

Do not over-tighten the mounting screws!
