RADAR beam path

GNSS antenna

5m (16ft)

● The GNSS antenna should be mounted as high as possible, however it is not recommended to mount the antenna on the top of a high mast where the motion of the vessel will cause the antenna to move and potentially reduce the accuracy of the GNSS position.

● Route the GNSS antenna cable to the AIS transceiver. If extension cables are required all junctions should be made using appropriate co-axial connectors and made watertight.

Connect the GNSS antenna cable to the GNSS connector on the AIS transceiver.

Possible alarm conditions are listed Table 5:

Alarm Description

TX Malfunction This alarm will occur if the MMSI has not

been configured.

This alarm can also occur if the radio hardware has failed to select the correct frequency, that the output power is too low or a transmitter shutdown has occurred. In this situation, ALR 001 is output over the PI. The alarm will be cleared if the transmitter recovers normal operation.

RX Channel x Malfunction This alarm occurs should the receiver hard-

ware malfunction. The receiver is identified by the value of x (as shown below). The following alarms will be generated over the PI in this condition: ALR 003 - Rx Channel 1 ALR 004 - Rx Channel 2 ALR 005 - DSC (Channel 70) If the receiver returns to normal operation this alarm will be cleared.

Operation

4.6.8 Messages

AIS text messages and Safety Related Messages (SRMs) can be received from other AIS equipped vessels and also sent to specific vessels (addressed messages) or sent to all vessels in range (broadcast messages).

Reception of an AIS text message is indicated by the presence of the message icon at the top of the screen. This icon is shown whenever there are unread AIS text messages. Messages can be reviewed and replied to via the In-box.

The transceiver can store up to a maximum of 20 messages in the In-box and 20 messages in the Sent folder. If the number of messages exceeds 20 then the oldest message will be overwritten.

When a Safety Related Message is received the user will be notified immediately with a pop-up showing the message. Standard text messages are not displayed on receipt, however the message icon will be displayed at the top of the screen.

AIS messages can be viewed, created and transmitted from the ‘Messages’ menu.

The available options are: Compose - takes you to the message composition screen In-box - takes you to the received message list view Sent - shows a list of recently sent messages.

To compose a new message, select the type of message from the drop down menu and the destination. This can be by directly entering the MMSI, or by selecting from a list of visible targets.

The message text is entered using the on screen keyboard. Messages are limited to 80 characters in length.

Class B transceivers are permitted to receive broadcast SRMs and broadcast text messages, however this function is not mandatory. Class B transceivers are not able to receive addressed SRM or text messages. There is therefore no guarantee that text messages or SRMs sent to a Class B transceiver will be received.

4.6.9 Long Range Messages

If the transceiver is connected to a long range communication system via the long range communications port then long range interrogations may be received. These are requests for information from a distant base station beyond normal AIS operation range.

The transceiver can be configured to automatically respond to Long Range (LR) interrogations, or you can opt to respond to any interrogation manually.

Page 45

Operation

Automatic response is the default setting, but this can be changed on the ‘Ra- dio and Long Range Settings’ menu.

When a Long range interrogation is received you will be alerted by an onscreen pop-up message.

In automatic response mode simply review and acknowledge the notification screen using ‘Acknowledge’. In manual response mode you should review the request and select either the ‘Respond’ or ‘Decline’ option as appropriate.

4.6.10 Help and Support Screen

This screen is available from the ‘System Settings’ menu and provides contact information for the product manufacturer.

It also provides relevant information from the User Manual.

4.6.11 User Settings Screen

4.12 Displaying AIS Targets

4.12.1 Target List

The Target List Screen is the primary screen for displaying AIS targets received. This is the first screen displayed when the unit is switched on, but can also be accessed from the Target List option on the main menu.

Figure 23 Target List Screen

By default the target list is sorted by range but can be sorted on any column by using the left and right ‘Function’ keys to select a column and pressing the 'Select' key to sort either in ascending or descending order. Navigation up and down the list is via the up and down arrow keys or scroll wheel. Selecting a highlighted target using the Select key will bring up more details of that target. The Options menu on this screen provides additional actions which can be performed on the target list.

Different symbols are shown for an AIS target depending on the type of target and its status, these are shown in Figure 24. These symbols are common to the Target list and Target plot displays.

4.12.2 Target Filtering

From the Target List options menu, if 'Show Filter Settings' is selected, a screen is displayed indicating which filter parameters can be set to reduce the amount of data displayed on screen. This screen can also be accessed through ‘System Settings’-> ‘User Settings’.

Filters can be toggled on and off on the target list by pressing the ‘Options menu’ key and selecting ‘Toggle filters off’. The bottom line of the target list shows how many targets are visible or filtered out. If a filter is set, the filter icon is displayed at the top of the screen.

The Filters icon does not represent CPA/TCPA alarm settings.

4.12.3 CPA/TCPA Settings

The transceiver can be configured to filter out approaching vessels which fall within certain limits. The Closest Point of Approach (CPA) defines a boundary around the own vessel upon which, if breached, will trigger the filter. Time to Closest Point of Approach (TCPA) can only be set if CPA is set, and will trigger the filter if the time to the CPA limit is breached.

These parameters are set on the ‘Filtering and CPA/TCPA Settings’ menu. The target list shows targets which trigger the TCPA/CPA filter red. These CPA/TCPA figures are calculated solely on AIS data and should not be

used for anti-collision purposes.

Note: Setting the CPA/TCPA filter will not activate the Filters Icon.

4.12.4 Target Plot

The Target Plot screen shows the location of other AIS equipped vessels and shore stations relative to your own vessel. The target plot screen provides a basic overview of AIS targets and should not be regarded as a substitute for

Page 52

Operation

display of AIS information on a dedicated electronic chart display system (ECDIS).

The plot range can be adjusted by rotating the scroll wheel which cycles through the ranges 0.2NM up to 100NM. The range relates to the radius of the outer range ring shown on the screen.

Individual targets can be selected by using the arrow keys. When selected a square outline will appear around the target and the vessel details will be shown on the left hand side of the screen.

By pressing the options menu key, additional display features can be selected. If the Own Vessel Details option is selected the left hand side of the screen will

change to show own vessel dynamic data. If the MOB Details Display option is selected, the target plot will change to

show only AIS-MOB, AIS-SART, and AIS-EPIRB devices. The left hand side of the screen will show the range and relative bearing to whichever target is currently highlighted using the arrow keys.

4.13 Micro SD card data input

On the front of the transceiver under the door on the lower left hand side is a socket for a Micro SD memory card. See Figure 25. This can be used to upgrade the unit firmware or to log port data. Note the orientation of the Micro SD card, which is critical to ensure the product is not damaged.

Page 53

Operation

Figure 25 Micro SD card Socket

4.13.1 Upgrading the Unit Firmware

If a Micro SD card that contains valid upgrade firmware is inserted into the card socket, the unit will recognize the new firmware and will display a message asking you if you want to install it. The system will guide you to the appropriate menu screen, where the firmware update can be applied.

4.13.2 Logging Ports to the Micro SD card

If a Micro SD card is inserted into the card socket, the AIS transceiver can be configured to output specific data to the card. This is accessed from the individual port menu (from the ‘System settings’ -> ‘Interfaces’ menu.) If the ‘Log port to SD Card’ option is set to ‘On’, data will be output from that port to the Micro SD card, if one is inserted into the card socket. Only one port can be logged to the Micro SD card at a time.

4.13.3 Saving/Loading Settings

From the ‘Save/Restore & reset settings’ menu, all system settings and transceiver configuration data can be saved to the Micro SD card, if one is inserted

Page 54

Operation

into the card socket. Settings previously saved can be restored, thus restoring the transceiver to a previous configuration. ‘Reset settings’ will restore the unit to its factory defaults and is protected by the unit password.

4.14 WiFi Feature

The AIS transceiver provides features to operate with vessel WiFi networks, or to create its own network. Access the WiFi menu through ‘Interfaces’ -> ‘Wi-

Fi settings’.

4.14.1 Client Mode

If client mode is selected, the transceiver will search for available WiFi networks to connect to. If one is selected a password may be required, and upon connection the details of the connection will be shown in the bottom right corner of the screen. Once a WiFi connection is made, the transceiver will output a range of NMEA sentences over the selected WiFi port.

4.14.2 Access Point Mode

If the transceiver is configured as a WiFi access point (AP) it will create its own WiFi network, allowing other WiFi enabled devices to connect to it. Once connections are made, a range of NMEA sentences will be transmitted from the transceiver to any connected devices.

4.14.3 Advanced WiFi Features

Within the ‘WiFi’ screen, certain parameters can be changed such as Channel Number, Protocol, Port, Encryption, etc. These are recommended for advanced users only.

WiFi is switched off by selecting ‘Disable’ in the ‘Select Operating mode’ box.

5 Inland mode

The information entered and transmitted in Inland mode is not the same as that transmitted in SOLAS mode. After switching modes, please check your voyage and vessel data settings to ensure the configuration is correct.

5.1 Mode SOLAS / Inland AIS

The transceiver supports both standard ‘high seas’ operation and ‘Inland AIS’ operation. Inland AIS is an extension of AIS intended for use on board vessels navigating Inland waterways.

5.1.1 Switching between ‘Class A’ and ‘Inland AIS’ Modes

To switch between operating modes select the ‘System settings' -> ‘Operating mode’ option. Set the ‘Operating mode’ setting to ‘Inland AIS’ or ‘Class A /SO-

LAS’ before saving the setting. When the transceiver is configured to operate in Inland AIS mode the word ‘INLAND’ is shown permanently in the Menu title bar.

5.1.2 Entering Inland vessel identification settings

Additional vessel identification information is required for Inland operation along with some changes to the standard AIS configuration. The following additional information must be entered into the AIS transceiver:

● A quality setting for the speed, course and heading data sources connected to the AIS is required. The quality setting can be ‘high’ or ‘low’ for each data source. The low setting should be used unless a type approved sensor (e.g. a gyro providing heading information) is connected to the AIS transceiver.

The additional identification information can be entered via the ‘Vessel data settings’ menu.

The following standard AIS vessel identification information must be updated for Inland AIS:

● The vessels ENI - this is an 8 digit number allocated to the vessel.

● The ship type as an ERI selected from the menu provided.

● The length and beam of the ship to the nearest 10cm (greater

accuracy than standard AIS configuration).

These updates are all made using the process described in section 4.7.2

Inland mode

Page 57

Inland mode

Neither Blue Sign terminal should be connected to any other point on the AIS transceiver side of any isolation barrier present in the vessel wiring.

5.1.3 Entering Inland Vessel Voyage Settings

Additional voyage related information is required for Inland operation along with some changes to the standard AIS configuration. The following additional information must be entered into the AIS transceiver:

● The vessel’s load status (Loaded, Unloaded, or Unknown).

● The number of blue cones or blue flag status for the cargo.

● The static draught of the vessel to the nearest centimetre.

● The number of crew, passengers and other shipboard personnel.

The additional identification information can be entered via the ‘Voyage data settings’ menu.

The voyage destination should be entered using UN terminal location codes and ERI terminal codes where possible when in Inland Mode

5.1.4 Inland Alarm Masking

Inland AIS installations do not typically include connection of external GNSS, Heading or Rate of Turn sensors to the transceiver. The system alarms associated with these sensors can be disabled in Inland mode through the ‘Alarm Settings’ screen.

5.1.5 Blue Sign Switch

When operating in Inland mode it is possible to connect a ‘blue sign’ switch to the AIS transceiver.

The transceiver provides an isolated input for Blue Sign switch connection. It comprises two connections BLUE_SIGN_P and BLUE_SIGN_N. When enabled for Inland Waterways operation and the BLUE_SIGN_P terminal has a positive voltage with respect to BLUE_SIGN_N the Blue Sign status will be present on the display and transmitted accordingly in AIS position reports. See Figure 26.

Suitable options for connection to the Blue Sign interface are shown in Figure

26. Settings for the blue sign switch are available by selecting the ‘System set-

tings’ option followed by the 'Operating mode’ sub menu. Select the ‘Blue sign switch’ option to set up the blue sign switch.

6.11.3 Heading Priority Scheme

Heading shall be taken from the highest priority sensor reporting any one of:

•HDT

•THS HDT and THS are only processed if they are from the currently selected Heading source. When no heading has been received on the selected port for 30 seconds, the port shall be deselected as a heading source, and a new source selected as described above

6.11.4 Rate of Turn Priority Scheme

Rate-of-Turn shall be taken from the highest priority sensor reporting ROT. ROT shall only be processed if they are from the currently selected Rate-ofTurn source. When no Rate-of-Turn has been received on the selected port for 30 seconds, the port shall be deselected as a Rate-of-Turn source, and a new source selected as described above.

6.12 Compatibility Mode

Some devices require the use of Compatibility Mode for correct operation. When operating in the standard mode the fix quality flag indicates the type of GNSS position that is being reported. In compatibility mode, the fix quality reported will either be No GNSS or GNSS. On the ‘Interfaces’ screen, under the configuration menu for each sensor port there is an On/Off toggle which can be set if Compatibility Mode is required for that port.

6.13 Message 24 Content

The Unit Serial Number transmitted in AIS Message 24B, in response to a Message 15 request, is encoded as follows (note that these characters represent individual bits in the data): wwww wwyy yxxx xxxx xxxx w = week (0 - 63) y = years since 2014 (0 - 7) x = incrementing number (0 - 2047)

Issues Possible cause and remedy

Technical Information

No data is being received by a connected chart plotter

The screen is not illuminated

The RED ‘Alarm’ icon is illuminated

• Check that the power supply is connected correctly.

• Check that the power supply is a 12V or 24V 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 or 24V supply.

• The unit may not have a valid MMSI. Check that the AIS transceiver is correctly configured with a valid MSSI.

• The VHF antenna may be faulty. Please check the connection to the VHF antenna and that the VHF antenna is not damaged. The alarm icon may illuminate briefly if the power supply is interrupted or the VHF antenna characteristics are briefly affected.

• No GPS position fix can be obtained. Please check the transceiver is located where the internal GPS antenna has a clear sky view or that an external GPS antenna is properly connected and installed. Review the GPS signal strength graph in ‘System settings / GNSS Source’.

• The power supply is outside the allowable range. Check that the power supply is within the range 9.6V to 31.2V

• If none of the above correct the error condition please contact your dealer for advice.

• Check for error and alarm messages in the ‘Alarms’ menu.

Technical Information

My MMSI is being received by other vessels but my vessel name is not shown on their chart plotter or PC.

If the guidance given in the table above does not rectify the problem you are experiencing, please contact your dealer for further assistance.

• Some older AIS devices and chart plotters do not process the specific class B message which provides the vessel name (message 24). This is not a fault of your AIS transceiver. software upgrades are available for may 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.

7.1 What’s in the Box

The items below are included in the junction box purchase. If any of these items are missing, please contact your dealer.

Figure 31 Junction Box - What’s in the Box

7.2 Installation

The junction box should be mounted within 2m of the AIS transceiver, to ensure that the cable can be run without compromising its performance.

1. Connect the two extension cables between the transceiver and the junction box.

2. Remove the lid of the junction box using a 3mm Allen Key. Route your accessory cables through the waterproof cable glands and find the appropriate terminal blocks to fix them to.

3. Use the connector diagrams shown in Figure 12 and Figure 14 as your guide.

4. Secure the earth/screen/shield of the accessory cables to the metallic strips of the junction box or to the appropriate connection on the terminal block.

5. By default, the 120 Ohm jumper connectors should all be fitted to terminate any unused ports. If a port requires no termination, then that port’s jumper can be removed.

6. Secure the accessory cables within the junction box with cable ties.

7. Refit the lid securely to ensure waterproofing.
