1.1 Safety warnings
1.2 General notices
Position source
All marine Automatic Identification System (AIS) transceivers utilise a satellite based location system such as the Global Positioning
Satellite (GPS) network.
The accuracy of a GPS position fix is variable and is affected by factors such as the antenna positioning, how many satellites are used
to determine a position and how long satellite information has been received for.
Compass safe distance
The compass safe distance of this unit is 0.2m or greater for 0.3° deviation.
RF emissions notice
Caution: The AIS transceiver generates and radiates radio frequency electromagnetic energy. This equipment must be installed and
operated according to the instructions contained in this manual. Failure to do so can result in personal injury and / or AIS transceiver

About your AIS class B transceiver
2 About your AIS class B transceiver
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 the Global Navigation Satellite System (GNSS) and communication
between vessels is by Very High Frequency (VHF) digital transmissions.
There are a number of types of AIS device as follows:
• Class A transceivers. These are similar to class B transceivers, but are designed to be fitted to large vessels such as cargo ships
and large passenger vessels. Class A transceivers transmit at a higher VHF signal power than class B transceivers and therefore
can be received by more distant vessels. They also transmit Class A transceivers are mandatory on all vessels over 300 gross
tonnes on international voyages and certain types of passenger vessels under SOLAS regulations.
• Class B transceivers. Similar to class A transceivers in many ways, but are normally lower cost due to the less stringent
performance requirements. Class B transceivers transmit at a lower power and at a lower reporting rate than class A transceivers.
• AIS base stations. AIS base stations are used by Vessel Traffic Systems to monitor and control the transmissions of AIS transceivers.
• Aids to Navigation (AtoN) transceivers. AtoN’s are transceivers mounted on buoys or other hazards to shipping which transmit
details of their location to the surrounding vessels.
• AIS receivers. AIS receivers will generally receive transmissions from class A transceivers, class B transceivers, AtoN’s and AIS
base stations but do not transmit any information about the vessel on which they are installed.
This product is an AIS Class B transceiver.
2.2 Static and dynamic vessel data
There are two categories of information transmitted by an AIS transceiver: static and dynamic data.
The vessel's dynamic data, which includes location, speed over ground (SOG) and course over ground (COG), is calculated
automatically using the internal GPS receiver.
Static data is information about the vessel which must be programmed into the AIS transceiver. This includes:
• Maritime Mobile Service Identity (MMSI)
• Vessel name
• Vessel call sign (if available)
• Vessel type
• Vessel dimensions
Page 4
About your AIS class B transceiver
An MMSI number is required in order for the AIS transceiver to operate. Please contact the relevant authority in your
country for more information.
!
In the United States of America, the MMSI and static data must only be entered by a competent installer. The end user
of the equipment is not authorised to enter their own vessel data.
!
In most countries the operation of an AIS transceiver is included under the vessel's marine VHF licence provisions. The vessel on to
which the AIS unit is to be installed must therefore possess a current VHF radiotelephone licence which lists the AIS system, vessel Call
Sign and MMSI number.
2.3 Important information for US customers
There are specific laws in the USA regarding the configuration of AIS class B transceivers.
If you are a US resident and intend to use your AIS class B transceiver in US waters, you should make sure that your retailer has
configured your product prior to supplying it to you. If your AIS transceiver has not been pre-configured please contact your dealer for
details of how to have it configured.

GNSS antenna
The transceiver is shipped with a GNSS Antenna an 10m of cable. If this cable is not sufficient to reach between the desired GNSS
antenna location and the transceiver you will need an extension cable. (Contact your dealer for details.)
Optional switch
A switch can be connected to the transceiver to enable and disable 'silent mode' (see section 3.2). A latching toggle switch is
required to use this feature.
VHF antenna cable
Please check that the VHF antenna you intend to use has sufficient cable to reach between the VHF antenna and the AIS transceiver
unit. If it is not sufficient you will need an extension cable. Please contact your dealer for details of suitable products. For reference the
VHF antenna connector type on the AIS transceiver unit is SO 239, and is intended to mate with a PL 259 connector.
VHF Radio Connector Cable
This cable is used to connect the VHF radio to the AIS transceiver. If you have an existing VHF voice radio connected directly to the
VHF antenna, you can disconnect the VHF radio from the VHF antenna and connect them both to the relevant connectors on the ASIS
transceiver.
Power and data cable
The AIS transceiver unit is supplied with a two metre long power and data cable as an accessory. If you require longer cables to reach
your power supply, please ensure the cables are capable of carrying currents of up to 2A peak and 200mA on average. Means of
connecting the cables together will also be required. The use of ScotchlokTM connectors is recommended for this purpose.
Chart plotter
To display received AIS messages as other vessels on your chart plotter, you will need to connect your AIS transceiver to your chart
plotter. Please refer to the user manual supplied with your chart plotter for details of how to connect and configure your chart plotter for
use with AIS devices. For general guidance your chart plotter should be configured to accept NMEA data at 38400 baud (sometimes
referred to as 'NMEA HS' in the plotter configuration menu). You may also need to enable the display of AIS targets in the chart options.
Alternatively if you use an NMEA2000 network on your vessel it is possible to connect the AIS transceiver to the NMEA2000 network via
a suitable cable. Please refer to your dealer for details of NMEA2000 cables.

Step 8 - Connecting to NMEA0183 compatible equipment
The two independent NMEA0183 data ports provide connection to your chart plotter and other NMEA0183 compatible equipment. Each
port consists of two wires colour coded as shown in the table in
appropriate connections on your NMEA0183 compatible equipment. Please refer to your equipment manual for more information.
The AIS transceiver has a high speed output port which operates at 38,400baud and a low speed input port which operates at 4,800baud.
The high speed port is intended primarily to connect to a chart plotter, while the low speed port is intended to connect to other
NMEA0183 devices. A multiplexing feature is provided, which means any messages which are received via the low speed port are
automatically transmitted via the high speed port. This is particularly useful when using a chart plotter having only a single NMEA0183 port.
An additional sensor such as a gyro-compass can be connected to the AIS transceiver via the low speed port and the AIS transceiver can
be connected via the high speed port to the chart plotter resulting in the chart plotter receiving both AIS information and heading
information simultaneously. Please ensure your equipment is configured to use the correct baud rate for the port it is connected to.

3. Once installation is complete, proAIS2 will launch automatically and a start menu folder and shortcut will be created for future use.
4.5 Configuration using proAIS2
For configuration purposes only, it is possible to power the AIS transceiver via its USB connection. This is useful if you wish to configure
your AIS transceiver away from the vessel power supply. The AIS transceiver will not transmit any data or acquire a GPS position fix
whilst powered by USB.
You will require the following information in order to configure your AIS transceiver:
•MMSI
• Vessel name
• Vessel type
• Call sign
Vessel dimensions and position of your GPS antenna installation.
For further assistance in configuring your AIS transceiver please refer to the Help menu within proAIS2.

Operation
When silent mode is active other vessels will not be able to receive your vessel information on their AIS devices.
Your navigational safety may be compromised as a result.

5 Operation
5.1 Using the AIS transceiver
Once the unit has been configured it is ready for use. Providing other vessels with AIS transceivers installed are within radio range of
your vessel you should see their details appear on your chart plotter or PC. These vessels will also be able to see your vessel on their
chart plotter or PC. It may take up to six minutes for your full vessel details to be visible to others.
Specific details of how to configure your chart plotter to make use of the AIS transceiver features will be given in your chart plotter
manual. If you are using charting software running on a PC, please refer to the instructions provided with your chart plotting software for
details of how to configure it to display AIS information.
5.2 Switch functions
When connected to the AIS transceiver following the instructions in section 3.2 an external switch provides the ability to set the AIS
transceiver into 'silent mode'. In silent mode the transmission of your own vessel position ceases, whilst the reception of other vessel's
AIS position continues. You should use silent mode if you do not wish your vessel data to be received by other AIS devices. When silent
mode is active the blue indicator will be illuminated.
5.3 Using proAIS2 with your AIS transceiver
The proAIS2 tool has a range of features to help monitor the performance of your AIS transceiver. To use the full range of features your
AIS transceiver must be installed as described in section
instructions provided in the help menu within proAIS2.

5.4 Indicator functions
The AIS transceiver includes a coloured indicator as shown in Figure 16. The state of the indicator provides information regarding the
status of the AIS transceiver.
Figure 16 Indicator location on the AIS transceiver unit
Page 30
Operation
The meaning of typical indicator configurations is shown in the table below and Figure 16 shows the orientation of the AIS transceiver.
Green indicator only
The AIS transceiver is powered up, has a position fix and has transmitted at least one vessel information
report.
Red indicator only
The AIS transceiver has detected a system error. The likely causes of this are detailed in the
troubleshooting guide in section
troubleshoot the cause of the error.
Blue indicator
When silent mode is activated using the optional silent mode switch the blue indicator is illuminated to
show that the transmitter is disabled.
Amber indicator only
The AIS transceiver is in 'transmit timeout' mode. This can be for a number of reasons:
• The unit has only recently been powered on and is obtaining a position fix prior to transmitting its first
vessel information report. (This process can take several minutes).
• Position fix has been lost. The AIS transceiver will attempt to regain position fix for 30 minutes before
entering an error state.
• The AIS radio channels are exceptionally busy so there is currently no available timeslot for
transmission.
• The unit has been in silent mode and after deactivating silent mode this amber indicator will illuminate
until the first AIS message has been sent
• The AIS transceiver has been commanded by the local authority (via an AIS base station) to cease
transmissions.

Troubleshooting
No data is being received by the chart plotter • Check that the power supply is connected correctly.
No indicators are illuminated • Check that the power supply is connected correctly.
The Red 'error' indicator is illuminated • The unit may not have a valid MMSI. Check that the AIS transceiver is
My MMSI is being received by other vessels
but my vessel name is not shown on their
chart plotter or PC
If the guidance given in the table above does not rectify the problem you are experiencing, please contact your dealer for further
assistance.
• Check that the power supply is a 12V or 24V supply.
• Check that the connections to the chart plotter are correct.
• Check that the power supply is a 12V or 24V supply.
correctly configured with a valid MMSI.
• The VHF antenna may be faulty. Please check the connection to the VHF
antenna and that the VHF antenna is not damaged. The red indicator may
illuminate briefly if the power supply is interrupted or the VHF antenna
characteristics are briefly affected.
• No GPS position fix can be obtained. Please check the transciever is located
where the internal GPS antenna has a clear sky view or that an external GPS
antenna is properly connected and installed. Review the GPS signal strength
graph available in proAIS2.
• The power supply is outside the allowable range. Check that the power supply
is within the range 9.6V to 31.2V.
• If none of the above correct the error condition please contact your dealer for
advice.
• Check for error and alarm messages in proAIS2
• Some older AIS devices and chart plotters do not process the specific class B
AIS message which provides the vessel name (message 24). This is not a
fault of your AIS transceiver. Software upgrades are available for many older
chart plotters which will correct this issue. The other vessel should update its
AIS unit and/or chart plotting software to receive AIS message 24.
