Introduction
2 Introduction
2.1 About AIS
The marine Automatic Identification System (AIS) is a location and vessel
information reporting system. It allows vessels equipped with AIS to
automatically and dynamically share and regularly update their position,
speed, course and other information such as vessel identity with similarly
equipped vessels. Position is derived from GLONASS or GPS and
communication between vessels is by VHF digital transmissions.

3.1 What’s in the Box?
Please ensure all items are present and if any of the items are missing please
contact your dealer.
Figure 2 What’s in the Box?
3.2 Preparing for Installation
In addition to the items provided with the transceiver the following items will be
required to complete the installation:
3.2.1 VHF Antenna
Connection of a suitable VHF antenna will be required for the AIS transceiver
to operate. The antenna cable should be terminated with a PL-259 (or UHF)
connector. A surge arrestor should be fitted in line with VHF antenna connector. See section 3.3.3 for more information.
Page 17
Installation and Configuration
Please take note of the warnings listed at the start of this manual regarding the
installation and use of antennas.
3.2.2 Antenna Cables
The supplied GNSS antenna is provided with 10 metres (32.8ft) of cable. If this
is not sufficient to reach between the desired GNSS antenna location and the
AIS transceiver you will require an extension cable. Please contact your dealer
for details.
3.2.3 GNSS Antenna Mount
A mounting bracket is required for the supplied GNSS antenna.
3.2.4 Data Interface Cables
Suitable screened, multi core cable will be required to connect the ships sensor (DGPS, Gyro etc.) data ports to the AIS transceiver.
3.3 Installation Procedures
Before beginning installation of your AIS transceiver, please ensure that you
read all of the instructions in this manual.

Installation and Configuration
3.3.1 Step 1 - Installing the AIS Transceiver
Please note the following guidelines when selecting a location for your AIS
transceiver:
● The AIS transceiver must be fitted in a location where it is at least
0.5m (1ft 8ins) from a compass or any magnetic device.
● There should be adequate space around the AIS transceiver for
routing of cables. See Figure 29 for details of the AIS transceiver
dimensions.
● The ambient temperature around the AIS transceiver should be
maintained between -15°C and +55°C (5°F to 131°F). Ensure
adequate ventilation is present when panel mounting the transceiver.
● It is recommended that the AIS transceiver be installed in a 'below
decks' environment protected from the weather.
● The transceiver is supplied with four self tapping screws for
attachment of the AIS transceiver to a suitable surface using the
supplied bracket. Please refer to Figure 5 for guidance.
● The transceiver can be panel mounted using the four self tapping
screws provided. Please refer to Figure 6 for guidance. Access
behind the panel is required when using this mounting option.
● The AIS transceiver should be mounted in a location where the
display is visible to the user at the position from which the vessel is
normally operated.
A pilot plug connection option is included in the 18 way connector located on
the rear panel of the AIS transceiver. To provide the pilot plug an optional accessory can be purchased.

3.3.2 Installing the GNSS Antenna
For mounting the GNSS antenna supplied with your AIS transceiver you will
require a one inch 14 TPI pole mount. Contact your dealer to source a mount
suitable for the installation location.
Please note the following guidelines when selecting a location for the GNSS
antenna:
● The GNSS antenna mount should be secured to a rigid surface.
● The GNSS antenna should be located where it has a clear,
unobstructed view of the sky overhead.
Page 23
Installation and Configuration
GNSS antenna should be at least 5m (16ft)
from RADAR or satellite communication
antennas. It should also be away from
the RADAR beam path and mounted
on a rigid surface.

5m (16ft)
● The GNSS antenna should be mounted as high as possible, however
it is not recommended to mount the antenna on the top of a high mast
where the motion of the vessel will cause the antenna to move and
potentially reduce the accuracy of the GNSS position.
● Route the GNSS antenna cable to the AIS transceiver. If extension
cables are required all junctions should be made using appropriate
co-axial connectors and made watertight.
Connect the GNSS antenna cable to the GNSS connector on the AIS transceiver.

3.3.3 Installing the VHF Antenna
Please note the following guidelines when selecting and locating the AIS VHF
antenna:
● The VHF antenna should be located as high as possible and
positioned as far from other antennas as possible.
● The VHF antenna should have omnidirectional vertical polarization.
● Where possible the VHF antenna should be installed at least 3m
(10ft) away from other transmitting radio, satellite and RADAR
antennas.
● Ideally the AIS VHF antenna should be mounted directly above or
below the ship’s primary VHF radiotelephone antenna, with no
horizontal separation and with a minimum of 2m vertical separation.
Refer to Figure 9 for further guidance.
● The VHF antenna cable should be kept as short as possible to
minimize signal loss. High quality, low loss coaxial cable appropriate
to the installation location should be used.
● The VHF antenna cable should be terminated in a PL-259 co-axial
connector for connection to the AIS transceiver.
● Any outdoor installed connectors in the antenna cables should be
waterproof by design.
Page 25
Installation and Configuration
VHF antenna should be at least
3m (10ft) from other transmitting radio,
satellite and RADAR antennas.
3m (10ft)
VHF antenna
● Antenna cables should be installed in separate signal cable channels
at least 10cm (4ins) away from power supply cables. Crossing of
cables should be done at right angles and sharp bends in the
antenna cables should be avoided.
● It is recommended that a suitable surge arrestor is fitted in-line with
the VHF antenna connector.
Connect the VHF antenna cable to the VHF connector on the AIS transceiver
as shown in Figure 10.
