User Manual VegaAIS AtoN Station © Vega Industries Ltd, June 2015
RF Emissions:
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
antenna.

Mechanical Description
1.3.1 Construction
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.
VegaAIS AtoN Station Page 9 of 54 VegaAIS V1.0.8
User Manual VegaAIS AtoN Station © Vega Industries Ltd, June 2015
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.

User Manual VegaAIS AtoN Station © Vega Industries Ltd, June 2015
1.3.3 Installation
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.

User Manual VegaAIS AtoN Station © Vega Industries Ltd, June 2015
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.

These connections are described below:
1.4.1.1 Power Supply / Ground
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 is the RS232 connection used for VegaAIS configuration and (optionally) for communications with a Vega smart beacon. Baud rate 38400bps, 8 bits data, no parity, one stop bit.
1.4.1.3 Sync Connection
This output provides a GPS sync pulse for flash synchronisation of AtoNs. The active sync pulse can be configured to be high or low. Flash character length is also configurable.
1.4.1.4 AtoN On Digital Input
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.
VegaAIS AtoN Station Page 16 of 54 VegaAIS V1.0.8
User Manual VegaAIS AtoN Station © Vega Industries Ltd, June 2015
1.4.1.9 Isolated Digital Inputs (1-8)
These are eight isolated digital inputs referenced to an isolated common. These may be individually configured to be a current source or sink.
1.4.1.10 Boot Input
This pin is used when reprogramming the VegaAIS unit in bootstrap mode. Not currently supported. This input must be left unconnected.
1.4.1.11 Weather Station Connector RS232 Rx and Tx
This is the RS232 connection used for Weather Station communications. Baud rate 38400bps, 8 bits data, no parity, one stop bit.
1.4.1.12 Weather Station Connector RS485-A, RS485-B
This is the RS485 connection used for Weather Station communications. Baud rate 38400bps, 8 bits data, no parity, one stop bit.
1.4.1.13 Weather Station Connector RS422-A, RS422-B
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.
