2Introduction
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 the Global Positioning System (GPS) 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, and 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. 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,
AtoNs and AIS base stations but do not transmit any information about the vessel on which they are
installed.
The Protec-W transceiver is a combined Class A transceiver / Inland AIS.
Figure 1 The AIS network
Introduction
Page 6
2.2 Static and dynamic vessel data
Information transmitted by an AIS transceiver is in two categories: static and dynamic data.
The vessel's dynamic data which includes location, speed over ground (SOG) and course over ground (COG)
is calculated automatically using the internal GPS receiver.
Static data is information about the vessel which must be programmed into the AIS transceiver. This includes:
●Maritime Mobile Service Identity (MMSI)
●Vessel name
●Vessel call sign (if available)
●Vessel type
●Vessel dimensions
2.3 AIS operation licensing
In most countries the operation of an AIS transceiver is included under the vessel's marine VHF licence
provisions. The vessel on to which the AIS transceiver is to be installed must therefore possess a current VHF
radiotelephone licence which lists the AIS system, vessel Call Sign and MMSI number. Please contact the
relevant authority in your country for further information regarding ship’s radio licensing requirements.

Warning: Class B transceivers are permitted to receive broadcast Safety Related Messages and
broadcast text messages, however this function is not mandatory. Class B transceivers are not able
to receive addressed Safety Related or text messages. There is therefore no guarantee that text
messages or SRMs sent to a Class B transceiver will be received.
3.12 Handling alarms
The Protec-W transceiver performs self checking functions continuously. If a self check fails an alarm will occur.
Possible alarm conditions are listed in Table 2.
Alarm condition Description
Transmitter malfunction This alarm can occur if there is a fault with the transmitter or if
the antenna VSWR exceeds allowable limits. The alarm will be
cleared if the transmitter recovers normal operation or the VSWR
measurement returns to an allowable value. If this alarm condi-
tion persists contact your dealer or installer.
Antenna VSWR exceeds limit This alarm condition can occur if the VSWR (Voltage Standing
Wave Ratio) of the AIS antenna exceeds pre-defined limits. This
alarm is cleared if the VSWR returns to an allowable value. If this
alarm condition persists contact your dealer or installer.
Receiver channel x malfunc-
tion
This alarm occurs should the receiver hardware malfunction. The
receiver is identified by the value of x. If the receiver returns to
normal operation this alarm will be cleared. If this alarm condition
persists contact your dealer or installer.
External EPFS lost This alarm occurs if the position from the external Electronic
Position Fixing System (i.e. GNSS) is invalid or lost.
No sensor position in use This alarm occurs if the transceiver has no valid position informa-
tion from any connected sensor.

3.14 Long range messages
If the Protec-W 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 Protec-W transceiver can be configured to automatically respond to Long range (LR) interrogations, or you
can opt to respond to any interrogation manually. Automatic response is the default setting, see section 3.16
for details of the menu option used to change this setting. Note that in automatic mode all requested information
is returned if it is available.
When a Long range interrogation is received you will be alerted by a notification screen as shown in Figure 19
(when automatic response is enabled) or Figure 20 (when manual response is enabled).
In automatic response mode simply review and acknowledge the notification screen using the ‘Acknowledge’
function key to return to the previous operating screen. In manual response mode you should review the
request and select either the ‘Respond’ or ‘Decline’ function key as appropriate.

Please note the following guidelines when selecting and locating the AIS VHF antenna:
●The VHF antenna should be located as high as possible and positioned as far from other antennas as
possible.
●The VHF antenna should have omnidirectional vertical polarisation.
●Where possible the VHF antenna should be installed at least 3m (10ft) away from other transmitting
radio, satellite and RADAR antennas.
●Ideally the AIS VHF antenna should be mounted directly above or below the ship’s primary VHF
radiotelephone antenna, with no horizontal separation and with a minimum of 2m vertical separation.
If it is located on the same horizontal level as other antennas, the distance apart should be at least
10m. Refer to Figure 44 for further guidance.
●The VHF antenna cable should be kept as short as possible to minimise signal loss. High quality. low
loss coaxial cable appropriate to the installation location should be used.
●The VHF antenna cable should be terminated in a PL-259 co-axial connector for connection to the
AIS transceiver.
●Any outdoor installed connectors in the antenna cables should be waterproof by design.
●Antenna cables should be installed in separate signal cable channels at least 10cm (4ins) away from
power supply cables. Crossing of cables should be done at right angles and sharp bends in the
antenna cables should be avoided.
●Connect the VHF antenna cable to the VHF connector on the AIS transceiver as shown in Figure 45.

4.4.3 Sensor configuration
The Protec-W transceiver has seven NMEA0183 (IEC61162-1/2) data ports for connection of ship’s sensors
and display equipment as described in Table 3. There are three input ports for ship’s sensor data and three
bidirectional ports for connection of display equipment such as Radar or electronic chart displays. It is
recommended that an AIS compatible electronic charting system is connected to the Protec-W transceiver for
display of AIS targets. To comply with IMO regulations the AIS must be connected to speed over ground
(SOG), course over ground (COG), heading, rate of turn (ROT) and position information sources.
The three sensor ports are input only data ports for the connection of data from ships sensors. The four
remaining ports are bi-directional high speed connections supporting data input and output from the AIS. These
ports are suitable for connection to ECDIS, AIS enabled RADAR displays and Pilot equipment.
All data input connections are optically isolated.
Table 3 Serial data ports
All sensor ports can be configured via the sensor configuration menu which can be found under the Main
menu>Installation>Sensor configuration menu option.
The sensor configuration menu also includes the ability to disable the requirement for external GPS sensors to
provide a DTM (Datum) sentence, as not all external GPS devices provide this sentence.
4.4.4 Junction box connections
The junction box provides screw terminal connections for each of the seven data ports. The connections and
functions of each connection are defined in Table 4. All connections are labeled on the junction box PCB for
clarity. A diagram showing connections available inside the junction box is provided in Figure 47.
Use of shielded cable is recommended when connecting ships sensors and display systems to the junction box
Connect the cable shield to the terminal block marked ‘shields’ in the junction box. It is possible to remove the
PCB from the junction box enclosure to aid connection of cables to the screw terminals during installation.

If an external GPS device which does not provide a DTM sentence is connected to the
transceiver and the transceiver is configured to require DTM sentences, the external GPS data
will not be accepted by the transceiver. If no DTM sentence is required the WGS84 datum will be
used as a coordinate origin and the external GPS device must be configured to output position
using this datum.
Do not connect the shield to both the external equipment and the junction box. Connect at only
one end.

An example of connection to external display equipment is provided in Figure 48, and connections to other
equipment and sensors follow the same scheme. To determine the ‘A’ and ‘B’ signal lines on external
equipment use a digital volt meter to measure the signal line voltage referenced to ground. If the voltmeter
shows a negative voltage the ‘A’ signal line is being measured, a positive voltage indicates the ‘B’ signal line.
Figure 48 Example connection to external display equipment
The junction box provides jumpers to select alternative line termination configurations for data input
connections from remote equipment. The line termination options are:
●None - no line termination, suitable for short cable runs less than 10m (as supplied).
●R - 120 Ohm line termination, suitable for longer cable runs greater than 10m.
●RC - AC 120 Ohm / 1uF termination. Not used.
Select the appropriate line termination option for each data input connection using the jumper adjacent to the data
input connection in the junction box. The jumper positions for each termination option are shown in Figure 49.

4.10 Silent mode switch connection
An external switch can be connected to the AIS transceiver to control silent mode. To use an external switch
silent mode settings must be configured appropriately as described in section 3.18.
The external switch should be of a latching single pole type and is connected to the ‘Switches’ terminals of the
junction box as shown in Figure 56. When the connected switch is made (short circuit) silent mode will be
enabled and the Protec-W will stop transmitting the vessel position to other AIS users.

4.11 Inland AIS
The Protec-W AIS transceiver supports both Class A (high seas / SOLAS) AIS operation and Inland AIS
operation. Switching between Class A and Inland AIS is possible via the menu system and this setting should
be made at installation depending on the environment the vessel operates in. Additional vessel and voyage
information is required for transmission when operating in Inland AIS mode and this should be configured as
described in the following sections.
4.11.1 Switching between ‘Class A’ and ‘Inland AIS’ modes
To switch between operating modes press the ‘Menu’ key and select the ‘Installation' sub menu followed by the
‘Inland configuration’ then the ‘Inland AIS Enable / Disable’ option. When the transceiver is configured to
operate in Inland AIS mode the ‘IL’ icon is shown permanently in the status bar.
4.11.2 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:
●The vessels ENI (unique European Identifier) - this is an 8 digit number allocated to the vessel.
●The ship type as an ERI code (4 digits) selected from the table provided in section 8.
●The length of the ship to the nearest 10cm (greater accuracy than standard AIS configuration).
●The beam of the ship to the nearest 10cm (greater accuracy than standard AIS configuration).
●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 main menu. Press the ‘Menu' key then navigate
through the ‘Installation’, 'Inland AIS’ submenus to select the ‘Inland vessel data’ menu. This screen allows
entry of the Inland specific information described above.
The following standard AIS vessel identification information must be updated for Inland AIS:
●The IMO number should be set to ‘0’ or ‘00000000’ for an Inland vessel.
●The Call Sign should be set to the vessel’s ATIS code (as programmed into the VHF radio)
●The standard AIS ship type should be set to the most applicable ship type - refer to the ship type table
in section 8.
These updates are all made using the process described in section 4.5.
4.11.3 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 vessels load status as ‘loaded’ or ‘unloaded’.
●The number of blue cones or blue flag status for the cargo (1, 2 or 3 blue cones, or blue flag).
●The static draught of the vessel to the nearest centimetre.
The transceiver stores Class A (high seas) and Inland AIS vessel and voyage data separately so
two independent configurations are required, one for Class A and one for Inland AIS. If the
transceiver is being installed on board an Inland vessel then the standard vessel and voyage data
configuration should be carried out prior to the additional Inland configuration described below.
Inland vessel dimensions - the length and beam of the ship are entered to the nearest 10cm
when operating in Inland AIS mode. This is in addition to the vessel dimensions derived from the
GPS antenna location entered during standard configuration (see section 4.5) which is entered
in meters. The Inland specific length and breadth dimensions should be rounded upwards to the
nearest meter when entering the standard configuration. Both sets of dimensions should relate
to the maximum rectangular size of the convoy.
Installation
Page 53
●The air draught of the vessel to the nearest centimetre.
●The number of crew, passengers and other shipboard personnel.
●The number of assisting tugboats (from 0 to 6).
The additional identification information can be entered via the main menu. Press the ‘Menu' key then select
the ‘Voyage data’ sub-menu. When the AIS transceiver is operating in Inland AIS mode the voyage data entry
screen will be extended to allow input of the additional information described above.
The following standard AIS voyage information must be updated for Inland AIS:
●Destination
The voyage destination should be entered using UN terminal location codes and ERI terminal codes where
possible.
4.11.4 Other Inland AIS settings
When operating in Inland mode it is possible to connect a ‘blue sign’ switch to the AIS transceiver and also to
manually configure the AIS position reporting rate. The connection of the blue sign switch is described in
section .
Settings for the blue sign switch and reporting rate are available via the main menu by selecting the ‘Installation’
option followed by the 'Inland configuration’ sub menu.
Select the ‘Blue sign settings’ option to set up the blue sign switch. The switch can be set to ‘Available’ if a blue
sign switch is connected or 'Unavailable’ if no switch is connected.
Select the ‘Reporting rate selection’ option to manually adjust the AIS position reporting interval. The available
reporting interval settings are:
●Autonomous mode (default).
●Once every 10 seconds.
●Once every 5 seconds.
●Once every 2 seconds.
4.11.5 Blue sign switch connection
An external switch can be connected to the AIS transceiver to indicate the blue sign state when in Inland AIS
mode. If a blue sign switch is installed then the switch should be set to ‘Available' as described in section 4.11.4.
The external switch should be of a latching single pole type and is connected to the ‘Switches’ terminals of the
junction box as shown in Figure 57. When the connected switch is made (short circuit) the blue sign status will
be set and transmitted accordingly in Inland AIS position reports.
Manual changes to reporting rate should be carried out with care and usually only on instruction
from the local authority.
Do not connect a voltage source to the blue sign switch connections.

6.2 Transmission intervals
The IEC61162 sentences are in general output in response to a specific event, such as initiation of a binary
message via the user interface. Certain messages are output over the ports at regular transmission intervals.
Table 11lists each sentence type and the transmission interval.
Table 11 IEC61162 transmission interval for periodic sentences
6.3 Sensor data input port
The sensor data input port schematic is shown in Figure 58. The optional 120 Ohm termination is selectable
via a jumper in the junction box and should be fitted in the ‘R’ position when long cables connecting to the data
source are required - see section 4.4.4. Each sensor data input port is isolated from other data port inputs and
from the transceivers internal power supply.
Figure 58 Input port schematic
A logical low input is defined as: A-B < -0.2V.
A logical high input is defined as: A-B > +0.2V.
The input impedance is approximately 54 kOhms without the junction box jumper fitted, and 120 Ohms with the
jumper fitted.

6.4 Bi-directional data ports
The input circuitry of the bi-directional data ports is identical to the input circuitry for the sensor data input ports
described in the preceding section. The output circuitry consists of a differential line driver IC (Texas
Instruments AM26LV31E) and is shown in Figure 59.
Figure 59 Data output port schematic
6.5 Output drive capability of bi-directional ports
Bi-directional ports can supply an output current of up to 30mA. The output voltages are 0 (low) and 3.3V (high).
Effective load resistance should be in excess of 100 Ohms.
6.6 DGPS port
The DPGS correction port is intended for connection to a DGPS beacon receiver. The port has the same
physical characteristics as the bi-directional data ports as described in the preceding sections. If connection of
a beacon receiver is not required this port can be re-configured as an additional bi-directional port to
IEC61162-2. See section 3.16 for port configuration options.
6.7 RS232 port
The RS232 port carries IEC61162 data via RS232 and is intended for connection to a PC during installation
and service. The port can also be used to connect to PC based charting applications for display of AIS data.
6.8 Input data sentence formats
All data input is via IEC61162 / NMEA 0183 sentences. The sentences used by the AIS transceiver are
documented in the subsequent sections. The sentence structure tables describe each field in the sentence
starting from the left most field (field 1) after the sentence identifier. All sentences are terminated with the
IEC61162 checksum shown as ‘*hh’. For details of the checksum calculation please refer to IEC61162-1.

6.8.7 GBS - GNSS satellite fault detection
This sentence is used to support GNSS receiver autonomous integrity monitoring (RAIM). Given that a GNSS
receiver is tracking enough satellites to perform integrity checks of the positioning quality of the position
solution, a message is needed to report the output of this process to other systems to advise the system user.
With the RAIM in the GNSS receiver, the receiver can isolate faults to individual satellites and not use them in
its position and velocity calculations. Also, the GNSS receiver can still track the satellite and easily judge when
it is back within tolerance.
This sentence shall be used for reporting this RAIM information. To perform this integrity function, the GPS
receiver must have at least two observables in addition to the minimum required for navigation. Normally these
observables take the form of additional redundant satellites.
