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
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
: static and dynamic data.

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.

4.4 Configuration using proAIS

Please ensure that you enter all static data accurately. Failure to do so could result in other vessels failing to identify your vessel correctly.
The vessel MMSI can only be programmed once using proAIS, please take care to programme your MMSI correctly. If you need to change the MMSI for any reason, please contact your dealer who will arrange to have the MMSI reset.
Follow the steps below to configure the AIS transceiver:
1. Connect your AIS transceiver to the PC using the RS232 lead as
described in section 3.2. Apply 12V power to the AIS transceiver as described in section 3.2.
2. Select the appropriate serial port in proAIS and press 'Connect'.
3. proAIS should launch with the 'static data' page active (see
Figure 14). If this is not the case please select the 'static data' page.
4. Carefully enter the data fields on the screen including:
• MMSI - the vessel's MMSI must be 9 digits in length and should
be the same as that used for any other digital radio equipment such as a VHF DSC radio.
• Ship's name - the ship's name can be up to 20 characters in
length.
• Call sign - the call sign can be up to seven characters in length. Not all vessels are issued with a call sign and it is acceptable to leave this field blank.
• Vessel type - select a vessel type from the drop down list which most closely matches your vessel.
• GPS antenna location - use the on-screen guide to specify the distances from your GPS antenna to the edges of the vessel as shown. The distances are entered in metres.
5. Select the desired switch from the following options:
• Press switch to send safety related message.
• Make switch to disable transmitter (This is required if you intend to use an external toggle switch to control silent mode).
• Press switch to toggle transmitter on/off (This is required if you intend to use the integrated switch to toggle silent mode).
• Switch has no function.
Please note: the integrated switch can only provide one of these functions at any one time. If you wish to change the function of the switch please return to this configuration process.
6. Set the blue indicator function.
• The blue indicator can be configured to show either the status of the switch or to show when AIS messages are being received from other vessels.
• Note that the blue indicator cannot perform both functions simultaneously.
Page 17
7. Set the baud rates to the required level for each of the serial ports.
• Set the RS232 baud rate to the required level. The default is 38,400. This is the baud rate used when communicating with a PC via the RS232 connection.
• Set the NMEA output (transmit) baud rate to the required level. The default is 38,400. This is the baud rate used when transmitting data to a chart plotter via its NMEA0183 input.
• Set the NMEA input (receive) baud rate to the required level. 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

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

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
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.

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 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.

Operation

proAIS Diagnostics 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.
Figure 16 proAIS Diagnostics page

proAIS Other vessels page

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

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.

proAIS Serial data page

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.

Operation

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.
Indicator lights
Blue Red 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.
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.

Troubleshooting

6 Troubleshooting

Issue Possible cause and remedy
No data is being received by the chart plotter
No indicators are illuminated
The Red 'error' indicator is illuminated
• Check that the power supply is connected correctly.
• Check that the power supply is a 12V supply.
• Check that the connections to the chart plotter are correct.
• Check that the power supply is connected correctly.
• Check that the power supply is a 12V supply.
• 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.
My MMSI is being received by other vessels but my vessel name is not shown on their chart plotter or PC
• 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.
