Introduction
2 Introduction
2.1 About AIS
The marine Automatic Identification System (AIS) is a location and vessel
information reporting system. It allows vessels equipped with AIS to
automatically and dynamically share and regularly update their position,
speed, course and other information such as vessel identity with similarly
equipped vessels. Position is derived from GLONASS or GPS and
communication between vessels is by VHF digital transmissions.

3.4 Connecting the equipment
Installation and configuration
3.4.1 Data connections
The accessory cable provides a simple method of implementing a typical
Class B installation with minimum difficulty. If the planned installation is more
complex it is recommended to use the optional fully wired cables and Junction
box for greater flexibility
An accessory cable is supplied with the product to provide connections to the
NMEA0183 bi-directional data ports. The cable has a pre-moulded connector
at one end which should be connected to the 18-way connector on the rear of
the unit.
The other end of the cable has colour coded wires ready for connection The
table in Table 1 lists the function of each colour coded wire for reference.

A multiplexing feature is provided, which means any messages which are
received via the NMEA 2 port are automatically re-transmitted via the NMEA
1 port. Thus two independent NMEA data streams, AIS and external data are
merged into one. This is particularly useful when using a chart plotter having
only a single NMEA0183 port, for example: An additional sensor such as a
gyro-compass can be connected to the AIS transceiver via the input port and
the AIS transceiver can be connected via the output port to the chart plotter
resulting in the chart plotter receiving both AIS information and heading
information simultaneously.

It is important to ensure that the equipment is configured to use the matching
baud rates.
3.4.2 Sensor configuration
For more complex installations the AIS transceiver has six NMEA0183
(IEC61162-1/2) data ports for connection of ship’s sensors and display
equipment as described in Table 2. and Table 3.
There are three input only ports for ship’s sensor data and three bi-directional
high speed ports for connection of display equipment. These can be
connected using an accessory cable pack purchased through your dealer.

Figure 27 AIS target symbols displayed
4.9.2 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 ‘Home’ > ‘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 On / 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 settings.
4.9.3 CPA/TCPA Settings
The AIS transceiver can be configured to identify 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 an alert.
Time to Closest Point of Approach (TCPA) can only be set if CPA is set, and
will trigger the alert if the time to the CPA limit is breached.
These parameters are set on the ‘Home’ > ‘System settings’ > ‘User settings’
> ‘Filtering and CPA/TCPA Settings’ menu.
The target list shows targets which trigger the CPA/TCPA alert in red.
Page 54
Operation
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.
4.9.4 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
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 0.1NM 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.
4.10 Micro SD card data input
On the front of the AIS transceiver under the cover on the lower left hand side
is a socket for a Micro SD memory card. See Figure 28. This can be used to
upgrade the unit firmware, display detailed charts or to log port data. Note the
orientation of the Micro SD card, which is critical to ensure the product is not
damaged.

Operation
Figure 28 Micro SD card Socket
4.10.1 Loading new charts
The AIS transceiver always contains a basic low resolution world chart.
More detailed resolution charts can be purchased and overlaid onto the AIS
transceiver’s chart display.
The AIS transceiver will read only Jeppesen C-MAP MAX format Micro SD
cards. See your dealer for available charts for your region.
Insert a C-MAP Micro SD card into the Micro SD card socket. The AIS
transceiver will then automatically overlay that higher resolution chart region
onto the relevant region on the AIS transceiver’s world chart.
Remove the Micro SD card and the region will revert back to the basic world
chart.
Page 56
Operation
4.10.2 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.
4.10.3 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 ‘Home’ > ‘System settings’ > ‘Interfaces’ menu.)
If the ‘Log port to SD’ 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.
4.10.4 Saving / Loading settings
From the ‘Home’ > ‘System Settings’ > ‘Advanced’ > ‘Save / Restore settings’
menu, all system settings and AIS transceiver configuration data can be saved
to the Micro SD card, if one is inserted into the card socket. Settings previously
saved can be restored, thus restoring the AIS transceiver to a previous
configuration.
4.11 WiFi Feature
The AIS transceiver provides features to operate with vessel WiFi networks,
or to create its own network. Access the WiFi menu through ‘Home’ > ‘System
settings’ > ‘Interfaces’ > ‘WiFi’.
4.11.1 Client mode
If client mode is selected, the AIS 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 AIS transceiver will
output a range of NMEA0183 sentences over the selected WiFi port to any
connected devices.
Page 57
Operation
4.11.2 Access point mode
If the AIS 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 NMEA0183 sentences will be transmitted
from the AIS transceiver to any connected devices.
4.11.3 Advanced WiFi features
Within the ‘WiFi’ screen, certain parameters can be changed such as Channel
Number, Protocol, Port, Encryption, etc. These are recommended for
