Introduction Page 93Introduction3.1 About AISThe 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 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 designed to be fitted to commercial 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 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. ●Inland AIS stations. Similar to Class A transceivers with additional features for use on Inland waterways. ●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. AIS 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 receive transmissions from Class A transceivers, Class B transceivers, AIS AtoNs and AIS base stations but do not transmit any information about the vessel on which they are installed. This product is an AIS Aid to Navigation (AtoN) transceiver.Figure 1 The AIS network
IntroductionPage 103.2 System overviewThis AIS AtoN is a self contained device supporting both Type 1 (transmit only) and Type 3 (transmit and receive) operation. It is primarily designed for installation in enclosed environments such as buoy equipment cabinets on physical AtoN structures. The AIS AtoN transceiver can be supplied with an optional Sensor Interface which interfaces to sensors (such as weather instruments) and transmits measured data via AIS messages to surrounding vessels and shore stations.The AIS AtoN has an exceptionally low power consumption making it suitable for installation on floating Aids to Navigation with solar charged power systems. The lowest power consumption is achieved when operating as a Type 1 AIS AtoN transmitting only position information. Further description of Type 1 and Type 3 operation is provided below.Figure 2 Typical AIS AtoN system3.2.1 Type 1 AIS AtoNA Type 1 AIS AtoN is a transmit only device using the FATDMA (Fixed Access Time Division Multiple Access) access scheme. This requires that the AIS AtoN is configured with fixed AIS time slots in which it will transmit AIS messages. Mobile AIS stations operating in the area where a Type 1 AIS AtoN is installed need to be aware of the time slots allocated to the AIS AtoN. The slots allocated to the AIS AtoN are 'reserved' by AIS Base Station transmissions covering the area in which the AIS AtoN is installed. This mode of operation therefore requires that an AIS base station is operating in the same area as the AIS AtoN and is configured to make the necessary slot reservations.3.2.2 Type 3 AIS AtoNA Type 3 AIS AtoN has transmit and receive capability and can therefore use either the FATDMA or RATDMA (Random Access Time Division Multiple Access) access schemes. The RATDMA scheme allows the AIS AtoN to internally allocate slots for transmission of AIS messages without reservation from an AIS Base Station.AIS receive capability also allows a Type 3 AIS AtoN to be configured and queried for status via AIS messages sent from a shore station (known as VDL configuration). An extension of VDL configuration is 'Chaining' where configuration and query commands are passed along a 'chain' of AIS AtoN stations to a distant station beyond the range of direct communication with a shore station.
Introduction Page 113.3 Supported AIS messagesThe transceiver supports the following AIS message types.ITU-R M.1371-4 Message numberDescriptionTransmitted / Received by AtoN TransceiverApplication6Binary addressed message Transmitted and receivedThe transceiver uses message 6 to send binary data (relating to connected sensors and systems) to a specific shore station. The transceiver can also receive addressed binary messages for the purpose of configuration and control.7Binary acknowledge message Transmitted and receivedThis message is transmitted to acknowledge receipt of a binary message. The transceiver can also receive acknowledgements relating to its own addressed binary transmissions.8Binary broadcast message TransmittedThe transceiver uses message 8 to broadcast binary data (relating to connected sensors and systems) to all other AIS stations in range.12 Addressed safety related message TransmittedThe transceiver can be configured to transmit an addressed safety related message to a specific shore station to alert the operator to an off position, vessel proximity or built in test failure condition.13Acknowledgement of received addressed safety related messageReceivedThe transceiver receives message 13 in acknowledgement of its transmission of message 12.14 Safety related broadcast message TransmittedThe transceiver can be configured to transmit a broadcast safety related message to all AIS stations in range to warn of an off position, vessel proximity or built in test failure condition.
IntroductionPage 1220 Data link management message ReceivedWhen operating as a Type 3 transceiver slot reservations made by a shore station using message 20 will be observed by the transceiver.21 Aids to Navigation report TransmittedThis is the primary message transmitted by the transceiver. It contains the position, identification and status of the transceiver.25 Single slot binary message Transmitted and receivedThis message can be used for remote (over the air) configuration of the transceiver and configuration of a ‘chain’ of transceivers.ITU-R M.1371-4 Message numberDescriptionTransmitted / Received by AtoN TransceiverApplication
AIS AtoN product variants Page 134 AIS AtoN product variantsThe AIS AtoN transceiver can be operated with or without connection to the optional Sensor Interface product which is available to purchase separately. The AIS AtoN transceiver can be configured to operate as either type 1 or type 3 either with or without connection to the Sensor Interface. Installation of an AIS AtoN transceiver without connection to a Sensor Interface will limit the functionality of the installation to transmission of AIS message 21 including the following information:●Name of AtoN●Position of AtoN●Status of AtoN (including AtoN health, Light health and status and RACON status)Installation without connection to a Sensor Interface is recommended when their is limited power availability and no requirement for the AIS AtoN to broadcast other information such as meteorological or hydrological data. When the AIS AtoN transceiver is installed with a Sensor Interface the capability is extended to enable the broadcasting of data from connected sensors and systems. However the power consumption of the combined AIS AtoN transceiver and Sensor Interface will be higher and therefore suited to an installation where power consumption is less critical.

Connecting external sensors and systems Page 237 Connecting external sensors and systemsThe AIS AtoN transceiver can be interfaced to external sensors and systems for the transmission of sensor data via the AIS network. Typically meteorological and hydrographic sensors are interfaced to the transceiver so that local conditions can be shared with other AIS users.The AIS AtoN transceiver can be connected directly to a limited number of external sensors and systems, or to a more extensive number of sensors and systems via the Sensor Interface. Section 7.1 describes the interfaces available without connection to the Sensor Interface while section 7.2 describes the interfaces available when connected to a Sensor Interface. 7.1 Connecting sensors and systems to the AIS AtoN Transceiver This section describes the interfaces available when the AIS AtoN transceiver is not connected to a Sensor Interface. In this configuration only the 18 way Link connector is used to connect to external sensors and systems. The light status, light health and RACON status internal circuits are identical. Figure 11 shows the internal circuit and examples of possible external circuits. 7.1.1 Light ON/OFF interfaceThis is an electrically isolated differential interface which monitors the ON/OFF status of the Light providing the Light used supports this functionality. Additional circuitry may be required to interface the Light status outputs to the transceiver. 7.1.2 Light health interfaceThis is an electrically isolated differential interface which monitors the health status of the Light providing the Light used supports this functionality. Additional circuitry may be required to interface the Light status outputs to the transceiver. 7.1.3 RACON status interfaceThis is an electrically isolated differential interface which monitors the status of the RACON providing the RACON used supports this functionality. Additional circuitry may be required to interface the RACON status outputs to the transceiver. 1 3

The ACE sentence is described in section 11.2.2. This sentence can be used to supply the status bits for transmission rather than sourcing from the hardware inputs.The source of the status information is configured using either proAtoN (see section 8). The following settings must also be configured using proAtoN:●Light fitted / not fitted●Racon fitted / not fitted●Racon monitored / not monitoredNote that the AIS AtoN ‘health’ bit is generated internally by the transceiver. However, if the ACE sentence is configured as the source for status information then the AIS AtoN ‘health’ bit is the combination of the internal transceiver health and the ACE sentence health bit. In this configuration if either the internal transceiver health or the external health status provided by the ACE sentence is set to ‘1’ (alarm) then the status will be transmitted as alarm.7.1.5 NMEA0183 portThe bi-directional NMEA port is available via the 18 way Link connector described in section 6.1.2. This port accepts and outputs NMEA0183/IEC61162-1 sentences for configuration of the transceiver and communication of binary message payload data (see section 7) to the transceiver for transmission in AIS messages. Whilst the transceiver is awake own position reports are also output to this port (as AIVDO messages) and in the case of a Type 3 transceiver remote vessel reports (as AIVDM messages) are also output.The electrical and interface specification for this port is as follows:●Four wire NMEA0183 / IEC61162-1/2 port (RS422 levels)●Baud rate 38,400baud●Isolated receiver circuitry, non-isolated transmitter circuitry7.2 Connecting sensors and systems to the Sensor InterfaceThis section describes the interfaces available when the AIS AtoN transceiver is connected to the Sensor Interface which include:●Two fully isolated analogue inputs●Two non-isolated analogue inputs●A light current sense loop●Five isolated digital inputs●Three non-isolated digital inputs / outputs●A fully isolated RS422 / NMEA0183 port●Two RS232 ports●An SDI-12 serial bus interface (one RS232 port is unavailable if this interface is used)●A relay drive outputConnection to the above sensor interfaces is made via connectors Sensor 1 and Sensor 2 as described in section 6.2.

The steps to complete the installation are as follows:1. Insert the CD into your PC running Windows (XP, Vista, 7)2. Navigate to the proAtoN folder on the CD3. Double click the ‘setup.exe’ item to start the installation process4. Follow on screen instructions to complete the installationFollowing successful installation the application can be launched from the proAtoN folder in the Windows start menu. USB device drivers for the transceiver are installed automatically during installation of proAtoN. 11S 33S
Configuration using proAtoN Page 338.2 Application layoutThe basic layout of the proAtoN application is provided in Figure 17.Figure 17 proAtoN application layout8.2.1 COM Port selectionWhen connected via USB, the COM ports associated with the AIS AtoN transceiver and Sensor Interface will be listed in the COM port selection menu. ●To operate proAtoN in transceiver configuration mode (type 1, 1S, 3 3S) select the ‘AIS AtoN Port’ option from the drop down and click the ‘Connect’ button.●To operate proAtoN in sensor configuration mode (type 1S and type 3S only) select the ‘AIS AtoN Sensor Port’ and click the ‘Connect’ button. 8.2.2 Read / Write configurationClicking the left hand button will transfer current configuration information from the AIS AtoN transceiver or Sensor Interface to proAtoN.Clicking the right hand button will configure the AIS AtoN transceiver or with the information currently displayed in proAtoN.It is possible to select transfer of configuration information relating only to the currently selected tab, or to all tabs by clicking the drop down arrow to the right of each button. The default operation for each button is to read or write data relating to the selected tab only. It is highly recommended that prior to deploying the AtoN the “Send all Configuration” option is used on the write button.8.2.3 Transceiver configuration mode tabsThe configuration and status of the transceiver is displayed through a number of tabs. ●Real AtoN tab - configuration of AtoN MMSI, name, type, dimensions, position and radio parameters.●Message schedule tab - configuration of FATDMA or RATDMA message schedules.COM Port selectionRead / Write congurationConguration tabsStatus bar

This icon indicates the current synchronisation status of the information displayed in that tab with the internal configuration of the AIS AtoN transceiver or Sensor Interface. The synchronisation status icons are shown in Figure 18.Figure 18 proAtoN tab synchronisation iconsSynchronisation is achieved by either writing the configuration displayed in proAtoN to the AIS AtoN transceiver or Sensor Interface (click the write configuration button), or reading the current configuration from the transceiver for display in proAtoN (click the read configuration button).8.2.6 Status barThe status bar displays the current connection status of the application (bottom left) and the current GNSS time (if available, bottom right). This applies to transceiver configuration mode only.8.3 AIS AtoN transceiver configurationThe following sections describe the configuration options available and their effect on the behaviour of the transceiver. Configuration of an AIS AtoN transceiver requires knowledge of the local AIS environment and may require interaction with shore infrastructure. Familiarity with the current IALA guidelines on the use of AIS Aids to Navigation (IALA A-126) is assumed.8.3.1 Configuration of ‘Real’ AtoN parametersThe following parameters associated with the ‘real’ AIS AtoN transceiver should be configured via the ‘Real AtoN’ tab:Green - Tab synchronisedRed - Tab not synchronisedBlue - Synchronisation in progressTab edited (sync required)
Configuration using proAtoN Page 35●MMSI - the MMSI number associated with the ‘real’ AtoN. Typically the MMSI number for a ‘real’ AtoN station follows the format 99MID1XXX where MID is the appropriate national MID and XXX is a number unique to this station.●Name - the name of the AtoN station as broadcast to other AIS users. Up to 34 characters are available for the name.●Type of AtoN - select from a list of possible types of AtoN. The types are as defined by IALA in IALA A-126.●Type of EPFS - Select the type of EPFS (Electronic Position Fixing System) used by the transceiver. Note this selection does not affect the hardware configuration, only the contents of the ‘Type of EPFS’ field in transmitted AtoN position reports. The transceiver is equipped with a GPS module by default. Alternatively for a fixed or shore based transceiver a surveyed position type can be selected. Note that when the surveyed position is selected the surveyed position is broadcast to other AIS users and GNSS position information is ignored.●Nominal position - Enter the nominal or charted position of the AtoN. This is the position transmitted to other AIS users for a fixed AtoN when the ‘Surveyed’ EPFS type is selected. For all other configurations this position is used to perform ‘off position’ calculations only; the actual GNSS position is broadcast to other users. ○The application can average the current GNSS position over 5 minutes and use this value for the nominal position. Click the ‘Get GNSS position’ button to the right of the latitude and longitude fields to begin this process.○The position accuracy can only be entered when the type of EPFS is set to ‘Surveyed’. The accuracy should be set in accordance with the accuracy of the surveyed position.●Off position alternate message enable - the current GNSS position is compared to the nominal position according to the algorithm defined in IALA A-126 Annex A, Example 1. The off position threshold distance is specified in metres. If the transceiver determines that it is ‘off position’ then the alternate reporting schedule for message #21 (index 2) is enabled. For example, the alternate reporting schedule could be configured to decrease the reporting interval if the AtoN has drifted off position. The off position flag in message #21 is set when off position regardless of this setting.The transceiver off position algorithm is always operational and compares the current GNSS position to the nominal position of the transceiver.●MMSI for addressed messages - this is the destination MMSI used for all addressed message types generated by the transceiver. This is usually the MMSI of a shore station collecting status information from the transceiver. It is also possible to enable the acknowledgement of received binary messages (via message #7 or #13).●Dimensions - the dimensions of the AtoN should be entered to the nearest metre. Guidance on the appropriate configuration of dimensions for various types of AtoN can be found in IALA A-126.●Radio channels - Selection of alternative radio channels for AIS transmission and reception is possible, however in most cases the default channels (AIS1 and AIS2) should be used.●Transmitter power level - The transmitter power level for the transceiver can be selected as 1W, 2W, 5W or 12.5W. The default value of 12.5W is appropriate for most scenarios.It is essential that valid nominal position is entered and that a reasonable off position threshold is entered. If the default nominal is left unchanged or an incorrect position is entered then the transceiver will always be ‘off position’ resulting in the GNSS receiver being permanently enabled. This will lead to significantly increased power consumption and the ‘off position’ flag in the Aids to Navigation report will be set.!
Configuration using proAtoNPage 368.3.2 Message schedule configurationThe layout of the message schedule tab is described in Figure 19.Figure 19 proAtoN message schedule tab layoutDefault messagesAn AIS AtoN position report is made using AIS message #21. This message occupies two AIS slots. The default configuration shown in proAtoN includes two message #21 schedule configurations. The first configuration, index 1, is the primary position reporting schedule for the transceiver. The second, index 2, is the alternate position reporting schedule selected when the ‘off position’ monitor is enabled and the AtoN is determined to be off position (see section 8.3.1). If the alternate ‘off position’ schedule is not required it can be deactivated by selecting the associated row in the message schedule table and clicking the ‘Deactivate’ button. When deactivated the alternate schedule will be greyed out.Adding additional messages to the scheduleAdditional binary data messages can be added to the schedule table by selecting the required message type from the drop down at the top of this tab, then clicking the ‘Add’ button. The available message types are:●Message #8 - for broadcast of binary data to all other stations in range. The binary data may be provided by the Sensor Interface or third party equipment connected to the transceiver. See section 9 for further information.●Message #6 - for transmission of binary data to an individual destination MMSI. The destination MMSI is set on the ‘Real AtoN’ tab. The binary data may be provided by the Sensor Interface (if present) or third party equipment connected to the transceiver. See section 9 for further information.●Message #12 - for transmission of text messages to an individual destination MMSI. The destination MMSI is set on the ‘Real AtoN’ tab. This schedule is used for transmission of alert messages (see section 8.3.7).●Message #14 - for broadcast of text messages to all other stations in range. This schedule is used for transmission of alert messages (see section 8.3.7).Up to four separate schedules are available for each binary message type. Each individual schedule has an index from 1 to 4 which is used to identify that schedule (for example, message #8 index 2). Access scheme selectionThe access scheme for each message must be selected as either FATDMA or RATDMA (see section 3.2). The selection is made by selecting the required row in the schedule table, then clicking on the current access scheme in that row. A drop down menu will then appear in that location allowing selection of the required access scheme. Add new message schedulesCurrent messages and schedulesDeactivate or removeselected schedule
Configuration using proAtoN Page 37●FATDMA Configuration of an FATDMA schedule continues in section 8.3.3.●RATDMA Configuration of an RATMDA schedule continues in section 8.3.4.8.3.3 FATDMA Schedule configuration Using the FATDMA (Fixed Access TDMA) access scheme the actual slot for each transmission made by the transceiver is specified. There are 2250 slots per minute (or frame) on each AIS channel. The scheduled slots must be reserved for the transceiver by an AIS base station operating in the same area using AIS message #20. Further information on FATDMA reservations and slot allocation schemes can be found in IALA A-124, Appendix 14.The parameters required for an FATDMA schedule are as follows.Channel 1 start UTCThis is the hour and minute for transmission on channel 1. This specifies the AIS frame (minute) within a day in which the start slot for channel 1 resides. Channel 1 start slotThis is the slot number for the first transmission on channel 1. The slot number can range from -1 (transmission disabled on this channel) to 2249. Note that each message #21 transmission occupies two slots and associated base station slot reservations must therefore reserve two slots.Channel 1 intervalThis is the interval in slots between transmissions on channel 1. The interval can range from 0 to 3240000 slots, which equates to an interval of one day. Typically the interval is set to 13500 slots (6 minutes) on each channel which results in an overall interval of 3 minutes.Channel 2 start UTCThis is the hour and minute for transmission on channel 2. This specifies the AIS frame (minute) within a day in which the start slot for channel 2 resides. Typically the channel 2 start time is offset by 3 minutes from the start time used for channel 1. With a 6 minute reporting interval on each channel this results in a transmission every 3 minutes on alternating channels.Channel 2 start slotThis is the slot number for the first transmission on channel 2. The slot number can range from -1 (transmission disabled on this channel) to 2249. Note that each message #21 transmission occupies two slots and associated base station slot reservations must therefore reserve two slots.Channel 2 intervalThis is the interval in slots between transmissions on channel 2. The interval can range from 0 to 3240000 slots, which equates to an interval of one day. Typically the interval is set to 13500 slots (6 minutes) on each channel which results in an overall interval of 3 minutes.11S 33S33S11S 33S
Configuration using proAtoNPage 38Example FATDMA scheduleA typical transmission schedule requires that the AIS AtoN transceiver transmit AIS message #21 every three minutes on alternating channels. The transmission schedule is presented diagrammatically in Figure 20.Figure 20 Example FATDMA scheduleThis schedule can be configured using the following values:●Channel 1 start UTC = 00:00 (the first frame of every hour)●Channel 1 start slot = 0 (the first slot in the frame, so slots 0 and 1 are used by the message #21 transmission)●Channel 1 interval = 13500 slots (this equates to a 6 minute interval as there are 2250 slots per minute)●Channel 2 start UTC = 00:03 (the third frame of every hour)●Channel 2 start slot = 0 (the first slot in the frame, so slots 0 and 1 are used by the message #21 transmission)●Channel 2 interval = 13500 slots (this equates to a 6 minute interval as there are 2250 slots per minute)The transceiver is now configured to report message #21 on channel 1 every 6th minute, and on channel 2 every 6th minute, but offset by three minutes from channel 1. This results in a transmission of message #21 every three minutes on alternating channels. The actual start slot selected for each channel will depend on the FATDMA allocations in the area of operation.8.3.4 RATDMA Schedule configuration Using the RATDMA (Random Access TDMA) access scheme the time for each transmission made by the transceiver is specified. The transceiver will determine the actual slots used for transmission based on internal knowledge of the AIS environment gained from the AIS receivers.The parameters required for an RATDMA schedule are as follows.Channel 1 start UTCThis is the hour and minute of the frame in which transmission will occur on channel 1. The slot used within this frame will be determined by the transceiver.Channel 1 intervalThis is the interval in minutes between transmissions on channel 1. A typical value is 6 minutes.Channel 100:0100:0200:0300:0400:0500:0600:0700:0800:0900:1000:1100:1200:00hh:mmChannel 1 interval13500 slots (6 minutes)Channel 200:0100:0200:0300:0400:0500:0600:0700:0800:0900:1000:1100:1200:00hh:mmChannel 2 interval13500 slots (6 minutes)Overall interval7500 slots(3 minutes)33S

The slot used within this frame will be determined by the transceiver.Channel 2 intervalThis is the interval in minutes between transmissions on channel 1. A typical value is 6 minutes.Example RATDMA scheduleA typical transmission schedule requires that the AIS AtoN transceiver transmit AIS message #21 every three minutes on alternating channels. The transmission schedule is presented diagrammatically in Figure 21.Figure 21 Example RATDMA scheduleThis schedule can be configured using the following values:●Channel 1 start UTC = 00:00 (the first minute of every hour)●Channel 1 interval = 6 minutes●Channel 2 start UTC = 00:03 (the third minute of every hour)●Channel 2 interval = 6 minutesThe transceiver is now configured to report message #21 on channel 1 every 6th minute, and on channel 2 every 6th minute, but offset by three minutes from channel 1. This results in a transmission of message #21 every three minutes on alternating channels. The exact timings of the transmissions within the selected minute will vary as the transceiver selects available slots using RATDMA.Channel 100:0100:0200:0300:0400:0500:0600:0700:0800:0900:1000:1100:1200:00hh:mmChannel 1 interval6 minutesChannel 200:0100:0200:0300:0400:0500:0600:0700:0800:0900:1000:1100:1200:00hh:mmChannel 2 interval6 minutesOverall interval(3 minutes)
Configuration using proAtoNPage 408.3.5 Virtual AtoN configurationThe transceiver can be configured to transmit position reports for up to five virtual or synthetic Aids to Navigation. This configuration is carried out using the Virtual AtoN(s) tab in proAtoN. Within this tab there are sub-tabs relating to each of the five virtual or synthetic AtoNs. The sub-tabs are visible at the left hand edge of the window. The layout of the virtual AtoN configuration tab is provided in Figure 22.Figure 22 Virtual AtoN configuration tab layoutThe following parameters are required to configure a virtual or synthetic AtoN. Note that the ‘real’ AtoN must be properly configured in order to make use of the virtual AtoN feature.Virtual / Synthetic AtoNEach virtual AtoN required must be separately enabled by checking the ‘Enable’ checkbox. The type of virtual AtoN can then be selected.●Virtual AtoNA virtual AtoN is transmission of message #21 for an Aid to Navigation that does not physically exist. A virtual AtoN may be used to mark a temporary hazard to navigation, e.g., a wreck. For further information on the use of virtual AtoNs please refer to IALA A-126, IALA O-143 and IALA guideline 1081.●Synthetic AtoNA synthetic AtoN is transmission of message #21 from an AIS station located remotely from the physical Aid to Navigation. An example of use is to provide an AIS AtoN target for a buoy or mark that is not capable of supporting AIS AtoN hardware.Virtual / Synthetic AtoN DetailsThe basic configuration of a virtual or synthetic AtoN is comparable to that required for a ‘real’ AIS AtoN. Note that the MMSI number format is different:●A virtual AtoN MMSI has the format 99MID6XXX, where MID is the appropriate national MID and XXX is a number unique to this station.●A synthetic AtoN MMSI has the same format as a real AtoN MMSI, e.g., 99MID1XXX, where MID is the appropriate national MID and XXX is a number unique to this station.The position of the virtual or synthetic AtoN must be configured appropriately to the position of the aid. Note that a virtual AtoN has no dimensions whereas the dimensions of a synthetic AtoN should be configured.Enable virtual AtoN and select typeVirtual AtoN subtabsVirtual AtoN detailsVirtual AtoN schedule
Configuration using proAtoN Page 41Virtual AtoN scheduleThe transmission schedule for a virtual or synthetic AtoN must be configured in the same way as that for the ‘real’ AtoN. The TDMA access scheme, start times and intervals must be configured in the virtual AtoN tab following the guidance in section 8.3.3 or 8.3.4 as appropriate. When an FATDMA schedule is used it is important to ensure the slot allocations used for the virtual and real AtoNs are different in every case. Also note that two consecutive slots are used for each virtual AtoN report.8.3.6 Status input configuration tabAIS AtoN position reports (message #21) contain status information encoded as a bit sequence. The status bits contain the basic operational state of a connected light and RACON along with the overall health of the transceiver itself. Connection of a light and/or RACON is optional and requires equipment with a suitable health output. Interfacing of light and RACON status is described in sections 6.1.3, 7.1.4 and 7.2.4.The status information can be obtained from one of three sources as described in section 7.1.4. The status input configuration tab is used to set the source and other associated parameters. The layout of the status input configuration tab is provided in Figure 23.Figure 23 Status input configuration tab layoutCurrent status (message 21)This section shows the current light and RACON status determined by the transceiver. The transceiver must be connected and powered from a DC supply in order for this display to operate correctly.Light & RACON configurationThis section allows the fixed parameters of the light and RACON to be configured. The check boxes should be set according to the physical configuration. For example if a light status output is connected to the transceiver then the ‘Light fitted’ check box should be checked. If a RACON is connected it is also possible to define if the RACON is monitored or not.Status bit sourceSelect the source for the status information to match the method used to provide status information to the transceiver (this is described in section 7.1.4).Status bit logicThe logical sense of the physical status bit inputs can be set here. This allows for interface of equipment with active high or active low status outputs.Current status display(when connected to transceiver)Set xed status as installedSet status bit sourceSet status input logic
Configuration using proAtoNPage 428.3.7 Alert messagesThe transceiver can be configured to transmit text messages for three different alert conditions.●An addressed or broadcast text message can be transmitted when the transceiver detects a Built In Integrity Test (BIIT) failure.●An addressed text message can be transmitted to an approaching vessel if the vessel comes within a configurable distance of the transceivers location. This function is only available with Type 3 variants and with full time receiver operation.●An addressed or broadcast text message can be transmitted when the transceiver determines that it is off position (see section 8.3.1). This message is in addition to use of the alternate schedule for off position reporting (if the alternate schedule is enabled) and does not replace that function.The layout of the alert messages configuration tab is provided in Figure 24.Figure 24 Alert messages configuration tab layoutBIIT failure actionsThis section allows configuration of the text message to be transmitted on detection of a Built In Integrity Test failure (BIIT failure). Such a failure may indicate a problem with the transceiver and it may be prudent to warn vessels not to rely on the information provided by the transceiver in this situation. Note that the health of the transceiver is always transmitted as part of the standard Aids to Navigation position report (message #21), however the status contained in that message may not be shown on all display systems.The available actions on BIIT failure are:●No action - no message is transmitted on detection of a BIIT failure.●Transmit message #14. A broadcast text message is transmitted on detection of a BIIT failure. The text content of the message must be defined in the ‘Message text’ box.●Transmit message #12. An addressed text message is transmitted on detection of a BIIT failure. The destination for the addressed message is configured on the ‘Real AtoN’ tab (see section 8.3.1).In addition to configuration of the BIIT failure action a schedule for the associated message must be configured in the ‘Message schedule’ tab. ●Message #14 Index 1 must be configured if the message #14 action is selected.●Message #12 Index 1 must be configured if the message #12 action is selected.Vessel proximity alertThis section allows configuration of the text message to be transmitted on detection of vessel breaching a defined radius (or guard ring) around the transceiver. This message can be used to warn approaching vessels of potential collision with the AtoN. The addressed message is automatically sent to all vessels that breach the guard ring radius. Congure BIIT failure message actionCongure vessel proximity alert actionCongure additional o position alert actionCongure SART Relay Mode
Configuration using proAtoN Page 43The available vessel proximity alert actions are:●Disable message #12 - the vessel proximity alert function is disabled●Enable message #12 - the function is enabled and the text content of the message to be transmitted must be defined in the ‘Message text’ box. The guard ring radius for the proximity alert must also be configured in the ‘Radius’ box; note that the value is set in metres.In addition to configuration of the vessel proximity alert a schedule for the associated message must be configured in the ‘Message schedule’ tab. ●Message #12 Index 2 must be configured if the message #12 action is selected.Off position alertThis section allows configuration of the text message to be transmitted when the transceiver detects that it is off position. The settings for off position detection are made on the ‘Real AtoN’ tab (see section 8.3.1). The configuration of an alternative off position message #21 reporting schedule is independent of the configuration of this text alert.The available off position alert actions are:●Disabled - no text message is transmitted when the transceiver determines that it is off position.●Transmit message #14. A text message is broadcast when the transceiver detects that is off position. The text content of the message must be defined in the ‘Message text’ box.●Transmit message #12. An addressed text message is transmitted on detection of an off position condition. The destination for the addressed message is configured on the ‘Real AtoN’ tab (see section 8.3.1).In addition to configuration of the off position alert a schedule for the associated message must be configured in the ‘Message schedule’ tab.●Message #14 index 2 must be configured if the message #14 action is selected●Message #12 index 3 must be configured if the message #12 action is selectedSART Relay ModeThis control enables or disables the repeating of SART (Search and Rescue Transponder) messages detected by the AIS AtoN. This functionality is only relevant to Type 3 devices as receivers are required to detect the messages.8.4 Transceiver diagnosticsThe proAtoN application provides a number of features to assist with installation of an AIS AtoN and diagnosis of fault conditions. These features are available through the GNSS, Serial Data and Diagnostics tabs in proAtoN.8.4.1 GNSS tabThe GNSS tab shows the status of the GNSS receiver built into the transceiver. This provides an indication of the quality of the GNSS satellite signals being received along with the current position of the transceiver.At least four satellites with a carrier to noise ratio in excess of 40 dBHz are required for an acceptable position fix. Relocating the transceiver or connecting an external GNSS antenna can help improve the signal quality and resulting position accuracy. The internal GNSS receiver supports SBAS (Satellite Based Augmentation Service) to enable improved accuracy and integrity of GNSS position fixes. The availability of SBAS depends on the installation location of the transceiver (the WAAS SBAS service covers most of the US and the EGNOS service covers Europe).8.4.2 Serial data tabThe serial data page shows all data output from the transceiver in NMEA0183 / IEC61162-1 format. It is also possible to send NMEA0183 / IEC61162-1 commands to transceiver if required for technical support or custom configuration. A facility to record the data to a file is provided by clicking the ‘Log to File’ button.
Configuration using proAtoNPage 44Certain sentence types can be filtered out of the output window by checking the relevant sentence type in the ‘Filters’ section of this tab.8.4.3 Diagnostics tabThe Diagnostics tab provides system version and status information. This information may be required when requesting technical support for the product. AtoN Details●The connected AIS AtoN Type is displayed as Type 1 or Type 3●The application and bootloader software versions for the connected AIS AtoN are displayed●The serial number of the connected AIS AtoN is displayedPower status●The VHF antenna VSWR (Voltage Standing Wave Ratio) as measured at the last AIS transmission is displayed. This value is for indication only. A value better than 3:1 is expected for a good antenna system. The alarm limit for antenna VSWR is set to 5:1. A perfect antenna would give a VSWR of 1:1.●The system supply voltage is displayed in volts. The supply voltage must be between 9.6V and 32.6V for correct operation. The supply voltage alarm will activate outside of this supply voltage range.Report generationClicking the ‘Create Diagnostics Report’ button will produce full report of the transceiver status. This report may be requested by technical support personnel. After clicking the button select a suitable file name and location for the report file before clicking save. Reported messagesDuring operation the transceiver will output a variety of status messages relating to the current operating state. These messages are for information only and do not represent a fault condition. Message text Description / ResolutionTX attempt failed (msg 6 no payload re-broadcast data)A transmission of message #6 has failed as the payload data required for this message was not provided (by either the Sensor Interface, or an external system).

This feature allows a configuration file to be created without access to the transceiver hardware. The file can be loaded at a later time and synchronised with the transceiver hardware.This feature is available using the ‘Save File’ and ‘Load File’ items available on the File menu. The configuration is saved as a .pad file using a format proprietary to the proAtoN application.When the proAtoN application is launched a new blank configuration file is created. You will be prompted to save this file if changes are made without saving the file prior to closing the application, or if a ‘New file’ is created from the File menu.
Operation Page 519 OperationOnce configured and connected to a power supply and antennas the AIS AtoN transceiver will operate autonomously. Correct operation can be confirmed by checking for reception of Aids to Navigation reports (message 21) using another AIS device. 9.1 Standby operationDuring operation the AIS AtoN transceiver will enter a low power standby mode between scheduled transmissions. The unit will not enter standby mode under the following conditions. ●USB interface connected - the AIS AtoN transceiver will not enter standby mode whilst the USB interface is connected to a PC. The USB interface should be disconnected once the AIS AtoN transceiver is configured and deployed.●GPS acquisition - the AIS AtoN transceiver will not enter standby mode for the first 12 minutes of operation with GPS position available after power is first applied. This period is used to acquire the current number of UTC leap seconds from the GPS system. This only occurs at initial power up and subsequently on four occasions during each calendar year when it is possible for the number of leap seconds to change.●Off-position algorithm - the AIS AtoN transceiver will not enter standby mode when the off position algorithm is active and the AIS AtoN transceiver is determined to be off position. Whilst off position the GPS receiver is permanently enabled in order to monitor the position according to the algorithm provided in IALA A-126 Annex A. Should the AIS AtoN transceiver return on position standby operation will resume.●Schedule configuration - the AIS AtoN transceiver will not enter standby mode if the configured reporting schedule prevents standby operation. The AIS AtoN transceiver will only enter standby mode when there is a minimum of 15 seconds between scheduled FATDMA transmissions or 1 minute and 5 seconds between scheduled RATDMA transmissions.●Vessel Proximity Alert - the AIS AtoN transceiver will not enter standby mode when the vessel proximity alert message is enabled. In this scenario, the transceiver will be continually monitoring AIS messages to establish the proximity of vessels.During operation the AIS AtoN transceiver will output AITXT sentences to the NMEA0183 port 1 indicating any conditions blocking entry to standby mode.11S 33SIf entry into standby mode is blocked by one or more of these conditions the power consumption of the AIS AtoN transceiver will increase significantly.!
Data messages and data sourcesPage 5210 Data messages and data sourcesThe transceiver can be configured to transmit a range of data messages in addition to the standard AIS AtoN position report. The purpose, content and means of configuring supported message types is described in the table below.Configuration of the AIS AtoN for capture of data for messages #6 and #8 is described in the following sections. The options available for data capture depend on the transceiver variant.10.1 Configurations without the Sensor InterfaceThe data payload for binary messages #6 or #8 must be provided by external equipment interfaced to the AIS AtoN transceiver using the NMEA0183 port 1 available at the Link connector on the AIS AtoN transceiver as described in section 7.1.5. The payload data for the message is requested by the transceiver using a proprietary MCR sentence and provided by the external equipment using the MPR sentence defined in section 11.2.9. 10.2 Configurations with the Sensor InterfaceThe Sensor Interface supports the construction of data payloads for the following messages:ID Message type Description and use Content sources6Addressed binary dataThis message is addressed to another individual AIS station, usually an AIS base station, which is configured to decode the message content. The message content is binary data in a standardised or proprietary format. The message may be used to communicate status information about the AtoN and / or meteorological and hydrographic data captured at the AtoN.The binary content for this message can be generated by the Sensor Interface, or provided by suitably configured third party equipment. See sections 10.1 and 10.2 for further information.8Broadcast binary dataThis message is broadcast to all other AIS stations. The message content is binary data in a standardised or proprietary format. The message may be used to communicate status information about the AtoN and / or meteorological and hydrographic data captured at the AtoN.The binary content for this message can be generated by the Sensor Interface, or provided by suitably configured third party equipment. See sections 10.1 and 10.2 for further information.12Addressed safety related messageThis message is addressed to another individual AIS station and contains safety related text. The text can warn of a failure of the AtoN equipment, alert an approaching vessel to danger of collision with the AtoN or indicate that the AtoN is operating off positionSee section 8.3.7 for further information.14Broadcast safety related message This message is broadcast to all other AIS stations and contains safety related text. The text can warn of a failure of the AtoN equipment or indicate that it is operating off positionSee section 8.3.7 for further information.131S 3S

There are a range of factors that influence the accuracy of the scaled value and installations may need to be optimised on a case-by-case basis.The formula used to scale values is: Scaled_value = (((Raw_value - offset) * dividend) /divisor) + kfactorWhere:●offset = the adjustment for raw ADC values that are not zero when the input voltage is zero (a situation that can be caused by some connection circuits).●dividend = the output range●divisor = the input range (resolution)●kfactor = zeroThe isolated ADCs (as described in section 6.2.1) have 16 bit resolution. The non-isolated ADCs, used for internal voltage and ISENSE measurements, have 12 bit resolution.Installers will need to establish the required scaling values theoretically depending on the use case, input them using the relevant shell commands described in Table 6 and adjust the values experimentally to optimise the result. Additional sensor shell commands, getadccont <ADC number; 0 = ISO ADC 1, 1 = ISO ADC 2> and getadccontscaled <ADC number> can be used to evaluate the results. getadccont is particularly useful for testing the raw output for the ADCs when zero input voltage is applied. This value can be used as the offset.For reference, and to enable resetting the values, the default values for the ADCs are:●Isolated ADC 1 and ADC 2○offset = 0, dividend = 1, divisor = 42, kfactor = 0●Internal ISENSE non-isolated ADC8○offset = 12, dividend = 5000, divisor = 4095, kfactor = 0●Internal supply voltage ADC○offset = 0, dividend = 180 divisor = 823, kfactor = 0isensethreshint: decimal threshold valueSets the threshold (in mA) at which the current OK flag is set / value reported in message #6.Default 100mA as defined for the GLA message #6. setisensescaleint dividendint divisorint kfactorint offsetUser accessible command to set the scaling for the ISENSE ADC values.See section 10.2.7 for details of the scaling method.setaltisensescaleint dividendint divisorint kfactorint offsetUser accessible command to set the scaling for the ISO ADC 1 ADC values.See section 10.2.7 for details of the scaling method.Command Parameter Description

Manual configurationPage 6011 Manual configurationThe AIS AtoN transceiver and Sensor Interface can be configured using standardised NMEA0183 (IEC61162-1/2) sentences developed for configuration of AIS Aids to Navigation transceivers. 11.1 Basic Type 1 AIS AtoN configuration (FATDMA operation) The following information is the minimum required configuration for a Type 1 AIS AtoN reporting message #21 only.●The AIS AtoN station must be configured with the 'real' AtoN MMSI using the AID command.●The AIS AtoN station must be configured with an Name, charted position, operating radio channels and dimensions using the ACF and ACE commands.●The AIS AtoN should be configured to broadcast message 21 using the AAR command. Note that the slots selected for the AIS AtoN transmissions in FATDMA mode must be reserved by a base station operating in the area in which the AIS AtoN will be deployed.11.2 NMEA0183 / IEC61162 configuration sentencesThe following section documents the standardised NMEA0183/IEC61162 sentences used for AIS AtoN configuration and control. Please refer to IEC61162-1 (Edition 4) for complete details of the configuration sentence structure.The configuration sentence formats described in this section are used to both configure the device and as the response format from the device when queried for current status. The query command format is as follows:For example the query command $ECAIQ,AAR*21 requests the transceiver output an AAR sentence containing the currently configured broadcast rates for the AIS AtoN station.Configuration sentences are communicated using the transceiver USB interface.11.2.1 AAR - Configure broadcast rates for AtoN stationThis sentence assigns the schedule of slots that will be used to broadcast Message 21 and other allowed AIS AtoN Station messages. It provides the start slot and interval between the slots used for consecutive transmissions for the message. The AIS AtoN Station should apply the information provided by this sentence to autonomously and continuously transmit the messages until revised by a new AAR sentence. The AIS AtoN Station, upon receipt of an AAR Query for this information, will generate sentences for configured messages providing the current broadcast schedule. New AAR assignments will override existing AAR assignments.11S 33S$--AIQ,ccc*hh<CR><LF>Sentence formatter of data being requested (e.g.,AAR)$--AAR,xxxxxxxxx,xx,xx,xx,xx,xxxx,x.x,x,xx,xx,xxxx,x.x,a*hh<CR><LF>Sentence status flag (see note 7)Slot interval channel 2 (see note 6)Start slot channel 2 (see note 5)UTC minute for channel 2UTC hour for channel 2FATMA or RATDMA setup (see note 4)Slot interval channel 1 (see note 6)Start slot channel 2 (see note 5)UTC minute for channel 1UTC hour for channel 1Message ID index (see notes 3 & 8)Message ID (see note 2 & 8)MMSI (see notes 1 & 8)
Manual configuration Page 6111.2.2 ACE - Extended general AtoN Station configurationThis sentence and the ACF sentence are used to configure the AIS AtoN Station parameters when it is initially installed, and later in order to make changes to the way it operates. This sentence supports system administration of the AIS AtoN Station operation.Note 1 The MMSI is defined in the AID sentence. This field contains the linkage between the MMSI definition (AID), Message 21 configuration (ACF, and ACE) and scheduling (AAR) of Message 21 transmissions.Note 2 Message ID is the message identification of the message being scheduled. When Message ID is 0 this indicates that the slots being defined will be used for chaining messages. These slots are not reserved on the VDL via a Message 20 until the competent authority requires their use and will reserve the slots at that time for the proper duration. These slots can be used for chaining or for MPR single transmission.Note 3 Message ID Index is used when there are multiple versions of a Message ID. This index value should start at 1.Note 4 Used to select whether the AAR is configuring an FATDMA schedule or RATDMA/CSTDMA schedule (0 indicates FATDMA, 1 indicates RATDMA)Note 5 For all messages which need to be transmitted in FATDMA mode, starting slot ranging from −1 to 2249 should be used. A value of –1 discontinues broadcasts of the message when the AAR sentence is sent to the AtoN Station, and indicates that no message has been broadcast if the AAR sentence is received from the AtoN Station. A null field indicates no change to the current start slot setting when sent to the AtoN Station, and indicates that the start slot has not been set, i.e. is unavailable, when the AAR sentence is received from the AtoN Station. For an RATDMA transmission schedule, this field will be Null.Note 6 For all messages which need to be transmitted, in FATDMA mode slot Interval ranging from 0 to (24*60*2250;once per day) and in RATDMA/CSTDMA mode, time interval ranges from 0 to (24*60*60) s. A null field indicates no change to the current slot interval setting when sent to the AtoN Station, and indicates that the slot interval has not been set, i.e. is unavailable, when the AAR sentence is received from the AtoN Station.Note 7 This field is used to indicate a sentence that is a status report of current settings or a configuration command changing settings. This field should not be null.“R’ = sentence is a query response“C” = sentence is a configuration command to change settings.Note 8 The MMSI/Message ID/Message ID index are used to reference a table of messages loaded using MPR, ACF/ACE; this sentence defines the broadcast schedule for each message. Each message in this table is referenced by the combination of MMSI, Message ID, and Message ID index.Note 1 AtoN status bits, indication of the AtoN status, default “00hex”: for a Virtual AtoN, this field should be00hex. The three most significant bits represent the page ID.Note 2 The off-position indicator is generated when this threshold is exceeded (distance in metres).Note 3 Determines the behaviour of AtoN for message acknowledgement (Message 7 and 13):0 will provide acknowledgement as defined by manufacturer,1 will not provide acknowledgement.Note 4 Off-position behaviour:0 – maintain current transmission schedule,1 – use new reporting interval configured by AAR using message ID index.Note 5 Synch lost behaviour:0 – silent,1 – continue as before.Note 6 Name of the AtoN: maximum 34 characters.Note 7 Reference point of reported position; should be given as dimension (aaabbbccdd) of the buoy.(See IALA A-126)Sentence status flag (see note 8)Dimensions (see note 7)Name of AtoN (see note 6)Synch lost behaviour (see note 5)Off position behaviour (see note 4)Acknowledgment procedure (see note 3)Off position threshold (see note 2)AtoN status bits (see note 1)MMSI $--ACE,xxxxxxxxx,hh,xxxx,x,x,x,c--c,xxxxxxxxxx,a,*hh<CR><LF>

Manual configuration Page 6511.2.10TSP - Transmit slot prohibitThis sentence is used to prohibit an AIS station from transmitting in the specified slots. The AIS Station receiving this sentence should not use the next occurrence of the indicated slots. This sentence is designed to be used to protect interrogation responses from interference from Base Station transmissions and for use with AtoN Stations. For an AtoN Station the Unique Identifier is the AtoN Station Real MMSI.11.2.11VER - VersionThis sentence is used to provide identification and version information about a talker device. This sentence is produced either as a reply to a query sentence. The contents of the data fields, except for the unique identifier, should be manufactured into the talker device. The unique identifier is the AtoN Station Real MMSI. In order to meet the 79-character requirement, a "multi-sentence message" may be needed to convey all the data fields.Note 3 This field is used to indicate a sentence that is a status report of current settings or a configuration command changing settings. This field should not be null.“R’ = sentence is a query response,“C” = sentence is a configuration command to change settings.Note 1 The MMSI is defined in the AID sentence and is the MMSI of the Real AtoN.Note 2 The sequential identifier provides an identification number from 0 to 99 that is sequentially assigned and is incremented for each new TSP sentence. The count resets to 0 after 99 is used. This sequential identifier is used to identify the Base Station’s response to this TSP-sentence when it replies with a slot prohibit status report (see TSR-sentence).Note 3 1 = Channel 1,2 = Channel 2.Note 4 This is for record keeping. It contains the hour, minute, and second of this request.Note 5 This is the slot from which the following slot offsets are referenced.Note 6 Slot offset of the first slot in the block of slots to be blocked from use by the Base Station.0 indicates no prohibited slots.Note 7 Total number of consecutive slots to be blocked from use by the Base Station.

Manual configurationPage 6611.3 Proprietary configuration sentencesThe following section documents the proprietary NMEA0183/IEC61162 sentences used for AIS AtoN configuration and control. These sentence relate mainly to configuration of data capture and integration with external equipment.Note 1 The device type is used to identify the manufactured purpose of the device. Choice of the device type identifier is based upon the designed purpose of the device. It is set into the equipment based upon the primary design of the device and remains constant even if the user defined talker identifier feature is used (see BCF-sentence). For AIS device types, use one of the following talker identifier mnemonics:AB: independent AIS Base Station;AD: dependent AIS Base Station;AI: mobile class A or B (see IEC 61993-2 and IEC 62287-1) AIS station;AL: limited AIS Base Station;AN: AIS aids to navigation station;AR: AIS receiving station;AS: AIS physical shore station;AT: AIS transmitting station;AX: AIS simplex repeater station;DU: duplex repeater station;UP: microprocessor controller;U#: (0 ≤ # ≤ 9) user configured talker identifier.Note 2 The unique identifier is used for system level identification of a station, 15 alphanumeric character maximum. For an AtoN Station, this is the Real AtoN MMSI number.Note 3 The data field length may be 32 characters maximum. The length of 32 characters is chosen in order to be consistent with similar data field lengths in the IEC 61162 standard. When large character lengths are used and the 80 character sentence limit would be exceeded for a single sentence, a series of successive VER sentences should be used to avoid the problem (using data fields 1 and 2 to ensure the multiple VER sentences are properly associated by the listener). Null fields can be used for data fields contained in other sentences of the series. Every VER sentence shall contain the unique identifier.Note 4 The manufacturer’s serial number for the unit. Note, this “internal” manufacturer’s serial number may or may not match the physical serial number of the device.Note 5 Vendor identification.Note 6 Depending on the number of characters in each data field, it may be necessary to use a “multi-sentence message” to convey a “VER reply.” The first data field specifies the total number of sentences needed, minimum value 1. The second data field identifies the sentence number, minimum value 1. Note 7 The third data field provides the sequential message identifier. The sequential message identifier provides a message identification number from 0 to 9 that is sequentially assigned and is incremented for each new multi-sentence message. The count resets to 0 after 9 is used. For a VER reply requiring multiple sentences, each sentence of the message contains the same sequential message identification number. It is used to identify the sentences containing portions of the same VER reply. This allows for the possibility that other sentences might be interleaved with the VER reply that, taken collectively, contain a single VER reply. This data field may be a null field for VER replies that fit into one sentence.$--VER,x,x,x,aa,c--c,c--c,c--c,c--c,c--c,c--c*hh<CR><LF>Hardware revision (see note 3)Software revision (see note 3)Model code (see note 3Manufacturer serial number (see notes 3 &4)Unique identifier (see note 2)Vendor ID (see note 5)Device type (see note 1)Sequential message identifier (see note 7)Sentence number, 1 to 9 (see note 6)Total number of sentences needed, 1 to 9 (see note 6)

This is used as part of the configuration of an AIS AtoN transceiver connected to a Sensor Interface; the information within the ACQ details the acquisition time the Sensor Interface needs from the AIS AtoN transceiver before a transmission is going to take place, thus allowing the Sensor Interface sufficient time to collect and average data as required for a transmission.When the AIS AtoN transceiver is not connected to a Sensor Interface the ACQ data is not required but will still get displayed when queried.Note 1 This field is used to indicate a sentence that is a status report of current settings or a configuration command changing settings. This field should not be null.“R’ = sentence is a query response,“C” = sentence is a configuration command to change settings.Sentence status flag (see note 1)MMSI$--MCR,xxxxxxxxx,Q,LRC,a*hh<CR><LF>

Firmware upgrade procedurePage 7413 Firmware upgrade procedureThe AIS AtoN transceiver and Sensor Interface firmware can be updated should a new version be made available. The firmware update is transferred using the USB interface. The pre-requisites for carrying out a firmware update are:●AIS AtoN Transceiver connected to a PC via the USB interface.●If a Sensor Interface is being updated it should be connected to the PC via the USB interface. It is not necessary to connect the Sensor Interface to the AIS AtoN Transceiver via the Link cable. ●The PC operating system must be Windows XP, Vista or 7. ●Prior installation of the USB driver (This is automatically installed when proAtoN is installed). ●A software update file for the AIS AtoN transceiver and/or Sensor Interface (available from your supplier).●The 'vxsend' PC software update utility (available from your supplier).To update the firmware carry out the following steps:1. Install and run the 'vxsend' utility (screenshot shown in Figure 33).2. Click the Browse (…) button for the Image file, then navigate to and select the appropriate update file.3. Select the COM port assigned to the AIS AtoN port or AIS AtoN Sensor port, depending on which element is being updated. 4. Click 'Start' and wait for the update to complete. Notification is given when the update has completed successfully.5. Power cycle the transceiver and confirm normal operation before it is deployed.Figure 33 vxsend utility screenshot11S 33S
