other provisions of the R&TTE directive 1999/5/EC.
See Appendix B Declaration of Conformance for a copy of the Declaration of
Conformance.
1.1.4 Quality Assurance
All manufacture and assembly is performed under ISO9001 certification.
Caution: This device generates and radiates electromagnetic energy. This device must be
installed and operated according to the instructions contained in this manual. Failure to do so can
result in product malfunction and / or exposure to potentially harmful levels of radio frequency
radiation.
Caution: Never operate this device unless it is connected to a VHF antenna.
The system has a Maximum Permissible Exposure (MPE) radius of 1m from the antenna. This
has been determined assuming the maximum power of the transponder and using a standard
monopole VHF antenna with a maximum gain of 3dBi and termination impedance of 50 ohms.
When installing the antenna and operating the equipment consider the following,
• Higher gain VHF antennas will require a larger MPE radius
• Do not operate the unit when anyone is within the MPE radius of the antenna
• The antenna should not be collocated or operated in conjunction with any other transmitting
The VegaAIS AtoN Station supports the following messages as defined in ITU-R M.1371-4:
• Message 21 - Aids-to-Navigation report
• Message 6 - Addressed binary message
• Message 8 - Binary broadcast message
Message 21 is the primary message for AIS AtoN systems as it is the standardised AtoN status
message. The VegaAIS unit complies with the message 21 definition as described in the ITU-R
specification above and the IALA Recommendation A-126 Ed 1.5.
The VegaAIS unit can also transmit monitoring data, either addressed (message 6) or broadcast
(message 8). Two data formats are currently supported, a proprietary format used to log data to
the VegaWeb server, and the IALA GLA format as described in Annex C, Table 4 of the IALA A126 Recommendation.
The VegaAIS unit can also transmit Meteorological / Hydrographic data. This data is only
transmitted as a broadcast message (message 8) and the data format conforms to the IMO
SN.1/Circ.289 (2 June 2010) Table 1.1 recommendation.
1.2.1 Aids-to-Navigation Report
As described above, the Aids-to-navigation report complies with the message 21 definition in ITUR M.1371-4 and IALA Recommendation A-126 Ed 1.5.
The AtoN status bits in message 21 may be generated in a number of ways:
• Fixed status bits
• Light on/off determined from digital input
• Light on/off determined from serial signal (Vega beacons only)
• Light on/off determined by beacon current
• Light ok/fail determined by digital input
• Light ok/fail determined by serial signal (Vega beacons only)
• Light ok/fail determined by light detected off when it should be on
• RACON presence determined from digital input
• RACON failure determined from digital input
These options can be selected using the VegaAIS Configuration Tool. AtoN and RACON status
monitoring is more fully described in SECTION 4 ATON AND RACON STATUS MONITORING.
1.2.2 Monitoring Report
Monitoring reports are described in SECTION 5 MONITORING REPORTS.
1.2.3 Meteorological / Hydrographic Report
Meteorological/Hydrographic reports are described in SECTION 6 METEOROLOGICAL /
HYDROGRAPHIC REPORTS.
The standard VegaAIS unit consists of a main enclosure and a lid. Where the current / voltage
sensor option is required, another enclosure is sandwiched between the main enclosure and the
lid.
The main enclosure which is common to all models houses the AIS engine including VHF
transmitter and receiver (type3 units only) as well as the AtoN monitoring electronics. This unit is
not user serviceable and, to minimise the risk of compromising the sealing, should not be opened.
Lid
Main Enclosure
The current / voltage sensor unit is mounted on top of the main unit and houses the screw
connections for the current / voltage sensor(s) as well as the glands for passing cables in and out
of this unit.
Current Sensor
Enclosure
The lid fits onto either the main unit or the current sensor unit depending on whether the current
sensor unit is fitted. The lid is assembled using self-tapping fasteners into the enclosure. Take
care not to over torque these screws when assembling the lid.
The VegaAIS unit is designed to be sandwiched under an AtoN that is mounted on the standard
three or four hole mount on a 200mm PCD – as shown below.
If this mounting option is chosen, the stainless steel anti-crush tubes must be fitted to prevent the
VegaAIS enclosure from bearing the weight of the AtoN.
Alternately, the VegaAIS unit may be secured using the four mounting lugs on the main enclosure.
1.3.2 Sealing
The VegaAIS unit is sealed to the IP68 standard against the ingress of moisture, dust, insects and
other environmental contaminants. Because the VegaAIS unit does not need to be opened for
configuration, these seals can remain undisturbed for extended periods. If the current sensor unit
is opened to connect the current sensor terminals, do not let any water accumulate in this
compartment and take care to ensure the sealing O ring is correctly located in its O ring groove
when reassembling.
As mentioned above, the VegaAIS unit may be mounted under an AtoN using a three or four hole
mount on a 200mm PCD. Alternately the VegaAIS unit may be mounted using the four mounting
lugs on the base of the main enclosure.
Installation details are shown below.
If an AtoN is mounted on top of the VegaAIS unit, the stainless steel anti-crush tubes must be fitted
to prevent the VegaAIS unit from bearing the weight of the AtoN. As can be seen in the schematic
above, these tubes sit proud of the top of the enclosure and therefore bear the weight and
clamping forces of the AtoN.
The VegaAIS unit is supplied with both a GPS and a VHF antenna – installation schematics shown
below. These may be mounted on any convenient mounting point with the following provisions.
• The GPS antenna must be mounted such that it has a clear view of the sky. Any
obstruction of this view will diminish the performance of the GPS antenna.
• The VHF antenna should be mounted as high as possible and as far away as possible
from any metallic structure that may interfere with transmission and reception.
• Both antennas should be mounted with the main axis of the antenna vertical.
Both the GPS and VHF antennas are potted at the antenna and use the IP68 Bulgin Buccanneer
connector to connect to the VegaAIS unit. The connection locations are shown on the VegaAIS
installation schematic – these connection locations are also labelled on the VegaAIS unit.
Furthermore, the polarities of these two connectors are reversed meaning that it is impossible to
connect either antenna to the wrong location.
The other electrical connections are described in the Electrical section below.
The number of electrical connections will depend on the VegaAIS model and options selected.
All units will have a RF antenna and a GPS antenna connection. The installation of these
antennas and their electrical connections are detailed in the Installation section above.
There are four other possible connectors on the main VegaAIS unit; these are called the Beacon
Connector, the Weather Station Connector, the Analogue Extended I/O Connector and the Digital
Extended I/O Connector. The position of these connectors is shown on the schematic below.
All connectors are labelled on the VegaAIS unit and all connectors have different pin counts and
polarity to ensure they cannot be incorrectly connected. Cables are supplied for all installed
connections. The supplied cables are 1.5m long with unterminated ends - as shown below.
All units will have at least the Beacon Connector as this contains the serial interface for the
configuration tool. The pinout for the Beacon Connector is shown below.

This input provides power for the VegaAIS unit. Voltage range: 10 – 36VDC. Max current: 2A.
The VegaAIS unit can be powered from the Beacon Connector, the Analogue Extended I/O
Connector, the Weather Station Connector or the Unidirectional Current sensor. The VegaAIS unit
will automatically switch between these inputs depending on which input is powered.
Do not connect directly to a battery or power supply - an external fuse must be fitted between the
battery/power supply and the VegaAIS unit.
When powering the VegaAIS unit via the Beacon connector, the Analogue Extended I/O connector
or the Weather Station connector, this fuse should be 2.5A. If it is required to disconnect the
VegaAIS unit from the supply, just disconnect the appropriate connector that is supplying the
power. If more than one connector is supplying power (e.g. a backup supply) then remove all
connectors supplying power to the VegaAIS unit. If necessary, mark the cables to be
disconnected to completely disconnect the supply so it may be done by an untrained operator.
When powering the VegaAIS unit via the unidirectional current sensor, the value of the fuse
depends on the load being powered from the unidirectional current sensor. This fuse should never
exceed 40A.
When powering the VegaAIS unit via the unidirectional current sensor, a readily accessible
disconnect device should be incorporated in the external power supply so that the VegaAIS unit
may be disconnected when required.
1.4.1.2 Beacon Connector RS232 Rx and Tx

This input can be used to indicate if the AtoN is on or off for use in the Message 21 AtoN Status
byte. This input has a configurable pull-up or pull-down resistor. The active polarity is also
configurable. Active polarity in this case means the polarity when the AtoN is on.
1.4.1.5 AtoN Fail Digital Input
This input can be used to indicate if the AtoN has failed for use in the Message 21 AtoN Status
byte. This input has a configurable pull-up or pull-down resistor. The active polarity is also
configurable. Active polarity in this case means the polarity when the AtoN has failed.
1.4.1.6 RACON Fail Digital Input
This input can be used to indicate if the RACON has failed for use in the Message 21 AtoN Status
byte. This input has a configurable pull-up or pull-down resistor. The active polarity is also
configurable. Active polarity in this case means the polarity when the RACON has failed.
1.4.1.7 RACON Present Digital Input
This input can be used to indicate if a RACON is present or not for use in the Message 21 AtoN
Status byte. This input has a configurable pull-up or pull-down resistor. The active polarity is also
configurable. Active polarity in this case means the polarity when the RACON is present.
1.4.1.8 Isolated ADC Inputs (A & B)
These are two isolated, differential analogue inputs. Input range 0 – 36VDC. 12 bit ADC.
These are eight isolated digital inputs referenced to an isolated common. These may be
individually configured to be a current source or sink.

This is the RS422 connection used for Weather Station communications. Baud rate 38400bps, 8
bits data, no parity, one stop bit.
1.4.2 Current Sensor Connections
If the optional current sensor unit is fitted, then removing the VegaAIS lid will expose the current
sensor terminals as shown below.
The diagram above shows the wiring where only the unidirectional current sensor is fitted and is
used to measure beacon current. Power is brought in through one gland (red and black wires) and
out to the beacon through the other (brown, blue and green). Many other combinations are
possible using up to four glands to route cables.
