1 INTRODUCTION
1.1 General Overview
Simrad’s AI50 is an Automatic Identifi cation System (AIS). It is an
autonomous and continuous information reporting system, operating
in the VHF maritime mobile band. It allows AIS equipped vessels to
automatically and dynamically exchange and display information with
similarly equipped vessels and shore based traffi c stations. Fig. 1.1
The AI50 uses a sophisticated automatic digital time sharing technology
which allows a large number of similarly equipped vessels within
VHF range of each other, to time share the same radio channel without
interference. This enables the automatic exchange of static information
like; MMSI (Maritime Mobile Service Identifi er) Number, Vessel’s Name,
Call Sign and Type. Also dynamic data like; Position, Course, Distance
and more, from ship to ship, and from ship to shore based traffi c stations.
The advantages of the AI50 are:
Increased awareness of the current shipping situation within your
VHF range through the exchange of data between vessels.
Improving traffi c management in busy shipping lanes through
exchanging information between vessels and shore based traffi c
stations.

Reporting information automatically in shipping areas where it is
mandatory.
WARNING
As with all electronic navigational equipment, it is only an
aid to navigation and should not be used as a substitute
for good seamanship. Remember - Maritime law requires
that you keep a good lookout at all times.
The position of a vessel on the screen is the position of
the most recent transmission and may not be the current
position.
1.2 About this manual
The manual combines operating and installation information for the AI50.
Operation is sub-divided into main working categories for easy reference.
1.3 SimNet/NMEA2000 Network System
SimNet is Simrad’s proprietary high speed data bus network complete
with NMEA2000. It provides intelligent sharing of data and control
information between a wide range of marine electronics and instruments.

2 INSTALLATION
2.1 General
The AI50 can be fl ush mounted or bracket mounted, however, to
determine the best possible location for good navigation, you need to
consider these few options:
For ease of use - keep it within easy reach
For good screen visibility - keep away from direct sunlight if
possible
Ensure good ventilation
Decide how and where, you are going to run the cabling from
the rear of the unit.
The AI50 is very simple to install, however, the performance of the
equipment is directly affected by the quality of the installation. Please
read these instructions carefully before attempting installation. If in any
doubt, consult a qualifi ed marine electronics engineer.
2.2 Panel Mounting
The transceiver requires a flat surface with an area of at least 172mm x
115mm (6.8in x 4.5in) for mounting Fig 2.1.
Allow sufficient space behind the unit for cable entry – at least 50mm
(2.0in), in addition to the depth of the unit, is recommended. The surface
should be rigid and sturdy enough to be able to support the weight of the

unit, taking into account the shock loads likely to be encountered when
the vessel is under way in heavy seas.
Remove the backing paper and stick the cutting template onto
your console or panel where the unit is to be mounted.
Drill a 2.5mm hole in each corner, where shown, to fasten the
unit.
Drill 8 x 6mm holes where shown to assist in cutting the case
peripheral hole.
Carefully cut the hole where shown on the template.
Remove the template.
Assemble case gasket to the rear of the AI50 unit.
Place the AI50 unit in the cut-out and fasten with 4 self tapping
screws into 2.5mm holes.
Carefully remove 4 corners, (3 left and 3 right supplied, ), from
the moulding rosette.
(Note: they are numbered 1 and 2 on rear)
Place the 4 snap fit, removable corner covers into place. (No.1
is placed in the bottom left and top right position, No. 2 is
placed in the top left and bottom right position.
2.3 Bracket Mounting
Using the supplied bracket as a template, hold it against the surface it is
going to be mounted on. With a marker pen, make a mark through the
centre of the holes and drill a 3.5mm pilot hole on each mark. Secure to
the surface with the supplied self tapping screws.
2.4 GPS Antenna
The antenna, ideally needs to be mounted as low as possible with a clear view
of the sky to minimise errors due to movement over and above the transitory
movement of the vessel. It can either be deck mounted, or mounted onto a rail.
Use only the cable supplied with the antenna to connect it to the AI50.
Note DO NOT connect your antenna using further extension cables as this may
degrade the reception to a point where it may not function correctly.
To minimize interference, place the antenna in a position away from steel
constructions, wires, metal masts, sources of electrical interference, such
as radar etc. If installing the GPS antenna close to other antennas, mount
it either above or below their radiation beams.

The antenna cable is terminated in a push fit connector (SMB). Push the
antenna plug firmly into the socket on the back of the AI50.
For a guide to the connections on the AI50 see Fig. 2.2
2.5 VHF Antenna
Note North American Users - To meet FCC (Federal Communications
Commission) rules on Radio Frequency Exposure, it is recommended
that the VHF antenna is mounted at least 3m (10ft) away from any area
accessible to any personnel on board. If this distance is achieved by
vertical separation, the antenna must be at least 5m (16.5ft) above deck.
This guideline applies only to antennas not exceeding 3dBi gain.
WARNING
Failure to observe these recommendations may expose
those within the MPE (Maximum Permitted Exposure)
radius of 3m (10ft) to RF absorption levels that exceed
the FCC safe limits.
The most important factor in the performance of any AIS transceiver will
be the quality and positioning of the antenna.

As the range of VHF signals are governed by line of sight, the antenna should
be placed as high as possible, while remaining clear of any metallic objects.
Long whip antennae are generally recommended for larger boats, although the
most popular antennae for marine use is 1m (3ft 3in) long. On sailboats these
are usually mounted on the masthead, where the length of the antenna keeps it
clear from the navigation lights and wind vanes. This type of antenna can also
be mounted on the cockpit roof or powerboat garages.
For maximum range, it is recommended that a VHF antenna specifically
tuned for use with an AIS is used, and mounted away from the standard
VHF antenna. Vertical separation is preferred, but where this is not
practical, at least 5 metre horizontal spacing is recommended
WARNING
The antenna coaxial cable and any connectors used must
be rated at 50Ω. Under no circumstances should standard
domestic TV cable and connectors be used. Incorrectly
rated cabling and connectors could result in power not
reaching the antenna, but also power could be reflected
back into the AI50 unit, damaging it in the process.
The quality of any connections and integrity of the cable will directly affect
the performance of the radio. Poor soldering or corrosion of the terminals
can impair performance. We recommend that screw or crimp terminal
type connectors are not used for any through deck fittings - a good quality
waterproof solder terminal connector will be less susceptible to poor
connection due to corrosion of the contacts.
To ensure the best performance of the radio, the antenna cable should be
routed where it is least likely to interfere with, or receive interference
from other electronic equipment, such as echo sounder transducer cables
and high current carrying cables.
The antenna cable should terminate in a standard marine PL259 plug
fitting. Connect the antenna plug to the socket on the back of the AI50
and screw the retaining collar down Fig. 2.3.
Note To avoid possible water damage to the transceiver, it is recommended that all
cables are looped to provide a drip path.
