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!
