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.

About your AIS class B transceiver
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 Positioning System (GPS) 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 transceiver,
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, and also transmits
more frequently. Class A transceivers are mandatory on all
vessels over 300 gross tonnes on international voyages and
certain types of passenger vessels under the SOLAS mandate.
• 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 basestations. AIS basestations are used by Vessel Traffic
Systems to monitor and control the transmissions of AIS
transceivers.
• Aids to Navigation (AtoN) transceivers.
AtoNs 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,
AtoNs and AIS basestations but do not transmit any information
about the vessel on which they are installed.
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
In most countries the operation of an AIS transceiver is included
under the vessel's marine VHF licence provisions. The vessel on to
Page 3
About your AIS class B transceiver
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.
An MMSI number is required in order for the AIS
transceiver to operate. Please contact the relevant
authority in your country for more information.
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.
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 static data.

The default is 4,800. If you are using an optional NMEA0183
device such as a heading sensor (see section 3.2) please select
the baud rate at which the NMEA0183 device is transmitting
data. If you are not using an optional NMEA0183 device this
baud rate should be set to the same level as the NMEA transmit
baud rate.
7. Once all data has been entered correctly, press 'Save static data
to AIS unit'. This will permanently store the data to the unit.
8. You will see a pop-up window warning you that the MMSI can
only be entered once and should therefore be entered correctly.
Please double check you have entered the correct MMSI.
9. All other static data can be modified by repeating the steps
above.
10. If you need to change the MMSI for any reason please contact
your dealer who will be able to reset the unit.

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
The integrated switch on the top of the unit (see Figure 2) can be
configured either to trigger transmission of a "Safety Related
Message" or to place the unit into "Silent mode". This choice is
made during configuration of the unit using the proAIS application;
please refer to 4.4 for further information on the configuration
options.
Safety related message
When configured to transmit a safety related message (SRM) the
switch will initiate broadcast of an AIS message containing the
vessels MMSI along with the text "MAYDAY MAYDAY". The switch
Page 19
must be pressed for at least two seconds to initiate this transmission
(to avoid accidental activation) and the blue indicator will illuminate
to indicate the message has been sent. Further safety related
messages cannot be sent until the blue indicator has extinguished
which will occur one minute after an SRM has been sent.
The SRM function is not a primary means of distress
call and cannot be relied upon as a means of distress
call.
Silent mode
When configured to place the unit into "Silent mode", each press of
the switch will toggle the AIS transmitter on or off. The switch must
be depressed for two seconds to activate silent mode to avoid
accidental activation. When the transmitter is off, the amber and
blue indicators will be illuminated and the AIS transceiver's position
will not be broadcast to other vessels. The position of other vessels
will still be received by the unit.
Silent mode can be used if you wish to only receive AIS messages
from other vessels but keep your own details private from other AIS
users.
Your vessel will not be displayed on other users, chart
plotters or PCs while your AIS transceiver is in silent
mode.
Operation
5.3 Using proAIS with your AIS
transceiver
The proAIS 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 3 and connected to a PC running the proAIS application.
proAIS GPS status page
The 'GPS status' page shows the signal strength of each satellite
being received and the dynamic data of the vessel. Satellite signals
shown as green bars are actively being used calculate a position fix.
If position fix cannot be achieved then no dynamic data will be
shown and all signal strength bars will be blue.
proAIS menus
This section describes the functions available via the proAIS
menus.
The proAIS 'File' menu includes the following functions:
Open log file - this includes the ability to open a log file previously
captured using the log file capture tool.
The proAIS 'Options' menu includes the following functions:
Beep on AIS transmission - the PC will make an audible beep
when an AIS message is transmitted.
Force connection - forces proAIS to make a connection with the
AIS unit even when no response is received from the unit.
The proAIS 'Help' menu includes the following functions:
About - details of the version number of the proAIS software you
have installed.

proAIS Diagnostics page
proAIS Other vessels page
The 'Diagnostics' page provides a range of information about the
AIS transceiver's status. Referring to the information in this page
may be useful if you are attempting to diagnose a potential issue
with the AIS transceiver's installation or operation.
The 'Other vessels' page provides a list of all vessels from which
AIS messages are being received. For each vessel the MMSI,
name, call sign, speed and course, position, range and bearing are
shown if available.

Operation
proAIS Messages page
proAIS Serial data page
The 'Messages' page provides a list of all text messages received
from other vessels. These are most likely to be safety related
messages which are requests for assistance from other vessels.
The 'Serial data' page provides a view of all incoming and outgoing
AIS messages. The messages are encoded in a special format and
it is not necessary to understand the meaning of the messages to
use the equipment. The serial data page includes the facility to
capture your AIS data during a journey and then play it back using
the 'open log file' command in the 'File' menu.

5.4 Indicator functions
The AIS transceiver includes four coloured indicators as shown in
Figure 20. The state of the indicators provides information
regarding the status of the AIS transceiver.

Amber
Green
Figure 20 Indicator location on the AIS transceiver unit
The meaning of typical indicator configurations is shown in the table
below and Figure 20 shows the orientation of the AIS transceiver.
The AIS transceiver is powered up, has a position fix and
has transmitted at least one vessel information report.
The AIS transceiver has detected a system error. The
likely causes of this are detailed in the troubleshooting
guide in section 6.
Page 23
When the switch function is configured to activate the
silent mode feature and the switch has been depressed
for more than two seconds, this combination of indicators
will be illuminated to show that the transmitter is disabled.
This arrangement of indicators will also be visible if the
AIS transceiver has been configured for the blue indicator
to signify received AIS messages. In this case the blue
indicator will rapidly turn on and off as messages are
received.
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 Basestation) to cease
transmissions.
When the switch function is configured to activate safety
related messages and the switch has been depressed for
more than two seconds the blue indicator will illuminate for
1 minute. It is not possible to send a safety related
message at a rate of more than once per minute.

•
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.
If the guidance given in the table above does not rectify the problem
you are experiencing, please contact your dealer for further
assistance.
The unit may not have a valid MMSI. Check that
the AIS transceiver is 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.
The GPS antenna may be faulty. Please check
the connection to the GPS antenna and that the
GPS antenna is not damaged.
The power supply is outside the allowable range.
Check that the power supply is within the range
9.6V to 15.6V.
If none of the above correct the error condition
please contact your dealer for advice.
