2.4 Cabling
Double shielded coaxial cables equal or better than RG-214 are
recommended when connecting the GPS and VHF antennas to the
AI80 system.
Coaxial cables should be installed in separate signal cable
channels/tubes and at least 10 cm away from power supply cables.
All outdoor installed connectors on the coaxial cables should be fitted
with preventive isolation such as shrink-stocking with silicone to
protect against water penetration.
Avoid sharp bends of the cables. A bend may change the
characteristic impedance of the cable.

Installation
Man_inst_AI80_r1 15
2.5 Location of the units
The units included in the AI80 system should be mounted with special
regard to the units’ environmental protection, temperature range and
cable length. Refer Technical specifications, page 1 onwards.
Antenna location
The AIS equipment, like any other ship borne transceiver operating in
the VHF maritime band, may cause interference to a ship’s VHF
radiotelephone. This interference may occur as a periodic (e.g. every
20 s) soft clicking sound on a ship’s radiotelephone.
This affect may become more noticeable when the VHF
radiotelephone antenna is located near the AIS VHF antenna, and
when the radiotelephone is operating on channels near the AIS
operating channels (e.g. channels 27, 28 and 86).
The figure below shows recommended location and distance between
the different antennas.
Simrad AI80 Installation Manual
16 Man_inst_AI80_r1
2.6 MKD unit
Mechanical installation
The MKD may be panel or bracket (option) mounted. The optional
mounting bracket may be ordered separately.
The unit should be mounted with special regard to the operator’s need
for easy operation.
Avoid mounting the MKD where it is easily exposed to sunlight, as
this will shorten the lifetime of the display. If this is not possible,
make sure the units are always covered with a protective cover when
not in use.
Panel mounting
Make sure that the mounting location includes space for plug and
cable bend.
The mounting surface must be flat and even to within 0.5 mm.
1. Remove the 4 front panel corners from the MKD.
2. Drill 4 mounting holes and make a panel cut-out according to
dimensional drawing, pages 5 and 6.

4. Apply the front panel corners.
Note ! Do not over-tighten the mounting screws.
Bracket mounting (option)
When the MKD is bracket mounted (item A100-85), it is not
weatherproof from the back. When bracket-mounted, the exposed
parts of the plugs should be protected against salt corrosion.
1. Locate the cradle on the mounting site and mark the 4 holes for the
screws on the mounting surface.
2. Drill the 4 holes and screw the cradle to the mounting surface.
3. Use the supplied screws to fasten the MKD to the left and right

2.11 GPS antenna
Mechanical installation
The GPS antenna included in the AI80 system is used for time
synchronisation and computation of backup position fix. In addition to
this GPS antenna, the AI80 should be connected to the vessel’s main
GPS system at the rear of the Mobile Unit. Sensor input 1-3 may be
used.
Optimum location of the GPS antenna is important to ensure
continuous track of all visible GPS satellites. The following should be
taken into consideration during installation:
• The GPS antenna must be installed where it has a clear view of the
sky and thus the objective is to see the horizon freely through 360
degrees with a vertical observation of 5 to 90 degrees above the
horizon.
• Small diameter obstructions, such as masts and booms, do not
seriously degrade signal reception but such objects must not eclipse
more than a few degrees of any given bearing.
• The antenna should be located at least 3 metres away from and out
of the transmitting beam of high power transmitters (S-band radar
and/or Inmarsat systems). This includes the ship's own AIS VHF
antenna if it is located separately.
Refer figure on page 15.
Use the supplied antenna mounting kit when mounting the antenna.
Appropriate crimping tools must be used.

GPS antenna offset arms
The mounting location for the internal GPS antenna and for the
main GPS antenna connected to the AI80 system, needs to be

figure shows the offset arms that have to be configured.
Refer Entering static data, pages 32 and 90.
Installation
Man_inst_AI80_r1 23
Checking the antenna cable
After the mechanical and electrical installation is completed, the
coaxial cables should be checked for short circuit between centre
conductor and shield (ground) with the antenna disconnected. If not
short-circuited, the antenna cable could be connected to the Mobile
Unit.
Sealing antenna connectors
The outdoor antenna connectors have to be sealed with self-bounding
tape and PVC/Vinyl tape for waterproofing.
Coil the self-bounding tape from one cable end to the other. Use at
least two layers of tape. After coiling, make a bounding by pressure of
fingers.
Coil at least two layers of PVC/Vinyl tape without stretching. After
coiling, make a bounding by pressure of fingers.
2.12 VHF antenna
The VHF antenna is not included in a standard AI80 system, but has
to be part of the AIS installation. A qualified antenna must cover
marine band (156 MHz - 164 MHz), have omni-directional vertical
polarization and provide 2 to 5 dB gain.
For installation of this antenna, refer to documentation delivered by
the antenna supplier. Refer also to the figure on page 15 for location.
Verify that there is no short circuit between centre conductors and
shield (ground) before the cable is connected to the Mobile Unit. Seal
the antenna connectors as described for the GPS antenna.
As an option Kongsberg Seatex AS may provide an antenna with part
number A100-58, shown in Appendix E - Optional VHF antenna.

Maintenance
Man_inst_AI80_r1 37
5 MAINTENANCE
5.1 General
All units in the AI80 system are “repair by replacement” units, and the
operator is therefore required to perform only a limited amount of
preventive maintenance on the units.
The service in the field is limited to:
• Replacing damaged GPS or VHF antenna cables
• Replacing failed AI80 system units
A damaged unit that has to be shipped back to the supplier, should be
sent in the original transportation box or another appropriate box. The
return address is provided in the first pages of this manual.
5.2 Periodic maintenance
The AI80 system should regularly be checked for firm and fixed
mounting of the chassis in order to avoid excessive resonances. All
connectors should be checked for good mechanical and electrical
connections. Cables should not be bent more than the minimum
recommended bending radius and there should be no sharp bends on
coaxial cables. All cables should be fixed tight and rigid to their
supporting structure (bulkhead, mast etc.) and special care should be
taken where cables run through holes with sharp edges.
MKD Units
The MKD will under normal use require little maintenance.
If the unit requires any form of cleaning, use fresh water and a mild
soap solution (not a detergent). It is important to avoid using chemical
cleaners and hydrocarbons such as diesel, petrol etc.
Mobile Unit
A properly operating Mobile Unit will indicate transmitting and
receiving messages by short blinks on the TX and MSG LEDs.
Inspecting the LEDs for normal operation gives a good indication of
the operating status. Any red LED indication means that further
investigation and servicing is necessary, see chapter 6.1.
Simrad AI80 Installation Manual
38 Man_inst_AI80_r1
5.3 Repair and modifications
The units in the AI80 system are not designed for customer repair. All
repairs and modifications of the units should be carried out by
qualified personnel. A failed unit should be shipped back to the
supplier for repair.
Exchanging antenna cables
1. Disconnect the power cable.
2. Dismount the damaged antenna cable. The new antenna cable
must be as straight as possible. Do not crush or crimp the

• Restart the Mobile Unit as described in the Simrad AI80 User
Manual.
• Remove the + 24 V power supply cable and then reapply
power.
6.2 Hardware problems
Hardware problems can be divided into the following categories:
• Power supply failure
• GPS receiver failure
• VHF transceiver failure
• GPS and VHF antennas and cables
• Interface cables
Simrad AI80 Installation Manual
42 Man_inst_AI80_r1
If the system outputs an alarm, the alarm condition can be read from
the display.
Power supply failure
If the unit periodically restarts approximately every one minute, this
could indicate a power supply failure.
Use the following procedure to check for power failure:
1. Check that external power has been connected to the rear
connectors.
2. Verify that supplied power is in accordance with technical
power specifications, page 1.
3. Verify that power cable dimensions are minimum 2.5 mm2.
GPS and VHF antenna cable connections
Typical problems when no GPS signal is received are that the GPS
antenna cable and/or connectors are damaged, or that the cables are
not properly connected. In order to check for antenna cable problems,
ensure that the GPS antenna is disconnected. The Ohm reading
between the centre and the screen should normally be infinite if there
is no short-circuit in the cable. Make a short-circuit in the opposite
end of the cable and measure the resistance. Now the reading should
be approximately 0 Ohm.
GPS and VHF antenna malfunction
Disconnect the GPS antenna cable at the rear side of the Mobile Unit.
Measure the resistance between the centre pin and shield in the cable
(with the antenna connected). The GPS antenna does not have a
defined resistance that can be measured. Therefore, before
measurements can be carried out, the antenna end of the cable needs
to be short-circuited. Measure between centre conductor and shield.
Resistance should be close to 0 Ohm.
Caution! Switch off the power before disconnecting the antenna!
GPS receiver failure
During normal operation the GPS LED blinks green once each
second. If the GPS LED on the front of the unit blinks amber, the
AI80 system computes no position data, the GPS receiver inside the
Mobile Unit should be checked.
Troubleshooting
Man_inst_AI80_r1 43
Disconnect the antenna cable at the rear side of the Mobile Unit. The
voltage output on the GPS antenna connector should be approximately
4.8 – 5.0 V if the GPS receiver supplies voltage to the antenna. If not,
this indicates problems with the GPS receiver. Disconnect and
reconnect power to see if the Mobile Unit starts up as normal. If not,
consult Customer Support for advice.
VHF transceiver failure
If there is no activity on the TX and/or the MSG LED on the front of
the unit, this indicates a transmitter or receiver problem. Disconnect
and reconnect power to see if the Mobile Unit starts up as expected. If
not, consult Customer Support for advice.
6.3 External data interface problems
External data connections may have incorrect:
• Data input from main GPS source
• Data input from vessel heading sensor
Check NMEA version, see table on page 29.
Data input from main GPS/GNSS source
Position data input to the AI80 system is received from the vessel’s
main GPS/GNSS receiver using an RS-422 serial line communication.
If data are not received in the AI80 Mobile Unit, the following steps
should be taken in order to check for missing position data:
1. Check that corresponding cable connections are correctly
terminated, refer chapter 3.4 and note on page 20.
2. If properly connected, check the serial line communication
(baud rate, parity, number of bytes transmitted, number of stop
bits) between transmitting (vessel GPS/GNSS receiver) and
receiving (parameters to be checked from display) end.
3. If OK, check that the position output format from the
GPS/GNSS receiver is in accordance with the expected input
position format, see page 29 and Appendix B - Digital
interface IEC 61162-1.
If the Mobile Unit still does not receive position data, consult
Customer Support for advice.
For details on electrical interface, see page 51.
Simrad AI80 Installation Manual
44 Man_inst_AI80_r1
Heading from vessel heading sensor
Heading data is received from the vessel’s gyro. If input data is
missing, the following steps should be taken in order to check for
missing heading data:
1. Check that corresponding cable connections are correctly
terminated, refer chapter 3.4 and note on page 20.
2. If correctly connected, check the serial line communication
(baud rate, parity, number of bytes transmitted, number of stop
bits) between transmitting (vessel heading sensor) and
receiving (parameters to be checked from the MKD unit) end.
3. If OK, check that the heading output format from the compass
is in accordance with the expected input heading format, see
page 28 and Appendix B - Digital interface IEC 61162-1.
If the Mobile Unit still does not receive heading data, consult
Customer Support for advice.
AIS unit restarts
If the AIS unit frequently restarts, please note that the AIS is
dependent upon 24 V DC/50 W, see Power supply failure on page 42.
1. Check that external power source has sufficient current rating
(recommended 4 A) and that
2. power cables are within specifications for such a power
consumption.

Hardware
The recommended wiring (the figures below are excerpts from IEC
61162-2, ed. 1) is as shown on the drawings. The A, B and C
designation correspond with the data signals as shown on figure on
page 20. There may be several listeners (receivers) but only one talker
(transmitter). For long lines we recommend to use a terminating
resistor (120 Ohm between A' and B' at the receiving end). Avoid
stubs or make them as short as possible. The common wire designated
"C" is the signal ground reference and this wire shall be isolated from
the outer shielding. The outer cable shield shall be continuous
(unbroken) through the installation, but shall not be terminated to any
part of the receiver.
Shielded twisted pair cable with third-wire is shown below. The
common "C" wire may be one wire of a pair of another port's common
connection wire "C", if they have the same destination.

Proprietary 61162-1 sentences
General
In order to configure and service the AI80 Mobile Unit there are some
proprietary messages that can be used on the PI or Pilot interface. The
AIS Mobile Unit uses the NMEA registered "STX" manufacturer’s
code. When setting parameters in the AIS Mobile Unit use the
$PSTXS command. To query the AIS Mobile Unit for information,
use the $PSTXQ command. Responses from the AIS Mobile Unit
uses the $PSTXR command. The proprietary messages comply with
IEC 61162-1 and have the following structure:

New IEC 61162-1 sentences
This subchapter contains a description of proposed IEC 61162-1
sentences due to AIS. Reference is made to IEC 61193-2, 2001, annex
B2 and IEC/PAS 61162-100.
ABK – Addressed and binary broadcast
acknowledgement
The ABK-sentence is generated when a transaction, initiated by
reception of an ABM, AIR, or BBM sentence, is completed or
terminated.
This sentence provides information about the success or failure of a
requested ABM broadcast of either ITU-R M.1371 messages 6 or 12.
The ABK process utilises the information received in ITU-R M.1371
messages 7 and 13. Upon reception of either a VHF Data-link
message 7 or 13, or the failure of messages 6 or 12, the AIS unit
delivers the ABK sentence to the external application.
This sentence is also used to report to the external application the AIS
unit's handling of the AIR (ITU-R M.1371 message 15) and BBM
(ITU-R M.1371 messages 8 and 14) sentences. The external
application initiates an interrogation through the use of the AIR-
sentence, or a broadcast through the use of the BBM sentence. The
AIS unit generates an ABK sentence to report the outcome of the AIR
or BBM broadcast process.
NOTE 1 Identifies the distant addressed AIS unit involved with the
acknowledgement. If more than one MMSI are being addressed (ITU-
R M.1371 message 15), the MMSI of the first distant AIS unit,
identified in the message, is the MMSI reported here. When the
Message ID is a general broadcast (ITU-R M.1371 messages 8 or 14),
this field is null.
NOTE 2 Indication of VDL channel upon which Message ID 7 or 13
acknowledgement was received. An "A" indicates reception on
channel A. A "B" indicates reception on channel B. If not available,
field is null.
Simrad AI80 Installation Manual
56 Man_inst_AI80_r1
NOTE 3 This indicates to the external application the type of ITU-R M.1371
message that this ABK sentence is addressing. Also see the message
IDs listed in NOTE 4.
NOTE 4 The message sequence number, together with the ITU-R M.1371
message ID and MMSI of the addressed AIS unit, uniquely identifies
a previously received ABM, AIR, or BBM sentence. Generation of an
ABK-sentence makes a sequential message identifier available for
reuse. The ITU-R M.1371 Message ID is used to determine the origin
of the message sequence identifier number. The following table lists
the origins by message ID:
ITU-R M.1371
Message ID Message Sequence Number source
6 sequential message identifier from ABM-sentence,
IEC 61162-1
7 addressed AIS unit's message 7, sequence number,
ITU-R M.1371
8 sequential message identifier from BBM-sentence,
IEC 61162-1
12 sequential message identifier from ABM-sentence,
IEC 61162-1
13 addressed AIS unit's message 13, sequence number,
ITU-R M.1371
14 sequential message identifier from BBM-sentence,
IEC 61162-1
15 no source, field shall be null
NOTE 5 Acknowledgements provided are:
0 = message (6 or 12) successfully received by the addressed AIS
unit,
1 = message (6 or 12) was broadcast, but no acknowledgement by
the distant addressed AIS unit,
3 = message could not be broadcast,
4 = requested broadcast of message (8, 14, or 15) has been
successfully completed, late reception of a message 7 or 13
acknowledgement "addressed to own-ship" MMSI – identified
by; destination MMSI, acknowledgement source MMSI,
message sequence identifier, and message type. Late reception
means that the AIS unit did not have an acknowledgement
process active for the acknowledgement that was received.
Appendix B - Digital Interface IEC 61162-1
Man_inst_AI80_r1 57
ABM – Addressed Binary and safety related
message
This sentence supports ITU-R M.1371 messages 6 and 12. It provides
an external application with a means to exchange data using an AIS.
The message data is defined by the application only – not the AIS.
This message offers great flexibility for implementing system
functions that use the AIS like a communications device. After
receiving this sentence, the AIS initiates a radio broadcast on the VHF
Data Link (VDL) of either message 6 or 12. The AIS will make up to
four broadcasts of the message. The actual number will depend on the
reception of an acknowledgement from the addressed "destination"
AIS. The default time between retries is 4 s. Retries will not be
attempted more frequently than 4 s. Retries stop when the appropriate
acknowledgement (See ITU-R M.1371 messages 7 and 13.) is
received. The AIS will make up to 4 broadcasts, original broadcast
plus three retires. This process could take 32 s to complete.
The success or failure of the reception of this broadcast by the
intended AIS unit is confirmed through the use of the "Addressed and
binary Broadcast Acknowledgement (ABK)" sentence formatter, and
the processes that support the generation of an ABK-sentence. The
AIS is also limited in the amount of encapsulated data that can be sent
in each slot and frame. If the length of the message would exceed five
slots, or the AIS broadcast would exceed the limit of 20 RATDMA
slot transmissions for the current frame, the AIS will return an ABK-
sentence with an acknowledgement of "2" – message could not be
broadcast.
NOTE 1 The total number of sentences required to transfer the binary message
data to the AIS unit. The first field specifies the total number of
sentences used for a message, minimum value 1. The second field
identifies the order of this sentence in the message, minimum value 1.
All sentences contain the same number of fields. Successive sentences
Simrad AI80 Installation Manual
58 Man_inst_AI80_r1
may use null fields for fields that have not changed, such as fields 4,
5, and 6.
NOTE 2 This sequential message identifier serves two purposes. It is both an
IEC 61162-1 "sequential message identifier field," and it is the
"sequence number" utilised by the ITU-R M.1371 in message types 6
and 12. The range of this field is restricted by ITU-R M.1371 to the
range of 0 to 3. This sequential message identifier and the destination
MMSI uniquely identifies a message. The sequential message
identifier may be reused after the "ABK" acknowledgement for that
sequence number is provided by the destination AIS unit. (See the
ABK-sentence formatter.)
NOTE 3 The MMSI of the AIS unit which is the destination of the message.
NOTE 4 The AIS channel that shall be used for the broadcast: 0 = no broadcast
channel preference, 1 = Broadcast on AIS channel A, 2 = Broadcast
on AIS channel B, 3 = Broadcast two copies of the message – one
copy sent on channel A and another copy sent on channel B.
NOTE 5 This is the content of the "binary data" parameter for ITU-R M.1371
message 6, or the "Safety related Text" parameter for message 12. The
first sentence may contain up to 48 "6-bit" symbols (288 bits).
Following sentences may contain up to 60 valid "6-bit" symbols (360
bits), if fields 4, 5, and 6 are unchanged from the first sentence and set
to null. The actual number of "6-bit" symbols in a sentence must be
adjusted so that the total number of characters in a sentence does not
exceed the "82-character" limit.
NOTE 6 To encapsulate, the number of binary bits must be a multiple of six. If
it is not, one to five "fill bits" are added. This parameter indicates the
number of bits that were added to the last 6-bit coded character. This
value shall be set to zero when no "fill bits" have been added. This
cannot be a null field.
ACA – AIS regional channel assignment
message
An AIS unit can receive regional channel management information
four ways: ITU-R M.1371 message 22, DSC telecommand received
on channel 70, manual operator input, and an ACA-sentence. The AIS
unit may store channel management information for future use.
Channel management information is applied based upon the actual
location of the AIS unit. An AIS unit is "using" channel management
information when the information is being used to manage the
operation of the VHF receivers and/or transmitter inside the AIS unit.
This sentence is used to both enter and obtain channel management
information. When sent to an AIS unit, the ACA-sentence provides
regional information that the unit stores and uses to manage the
internal VHF radio. When sent from an AIS unit, the ACA-sentence
Appendix B - Digital Interface IEC 61162-1
Man_inst_AI80_r1 59
provides the current channel management information retained by the
AIS unit. The information contained in this sentence is similar to the
information contained in an ITU-R M.1371 message 22. The
information contained in this sentence directly relates to the
"Initialisation Phase" and "Dual Channel operation and Channel
management" of the AIS unit as described in ITU-R M.1371.
NOTE 1 This is used to bind the contents of the ACA and ACS sentences
together. If provided by the AIS, the ACS sentence shall immediately
follow the related ACA sentence, and both sentences shall contain the
same sequence number. The AIS generating ACA and ACS sentences
shall increment the sequence number by one each time an ACA/ACS
pair is created. After "9" is used, the sequence numbering process
shall begin again from "0". If the sequence numbers do not match, the
information contained in an ACS sentence is not related to the
information in an ACA sentence. The ACS sentence may be used to
respond to an "ACA Query-sentence" (See IEC 61162-1, § 5.3.2.).
The AIS shall respond by providing ACA/ACS pairs for each of the
stored regional operating settings. At any given time, the maximum
number of pairs is eight. When an ACS sentence is not sent following
an ACA sentence, the sequence number may be null.
NOTE 2 Value of 1 nautical mile to a value of 8 nautical miles (with a
resolution of 1 nautical mile)
NOTE 3 VHF channel number, see ITU-R M.1084, Annex 4
NOTE 4 Value of 0, bandwidth is specified by channel number, see ITU-R
M.1084, Annex 4
Value of 1, bandwidth is 12,5 kHz.

Value of 1, transmit on channel A, receive on channels A and B
Value of 2, transmit on channel B, receive on channels A and B
Value of 3, do not transmit, receive on channels A and B
Value of 4, do not transmit, receive on channel A
Value of 5, do not transmit, receive on channel B
NOTE 6 Value of 0, high power
Value of 1, low power
NOTE 7 Source identifiers:

geographical area message,
C, IEC 61162-1 AIS Channel Assignment sentence,
D, DSC Channel 70 telecommand, and
M, operator manual input.
This field should be null when the sentence is sent to an AIS.
NOTE 8 This value is set to indicate that the other parameters in the sentence
are "in-use" by an AIS unit at the time that the AIS unit sends this
sentence. A value of "0" indicates that the parameters are not "in-use,"
and a value of "1" indicates that the parameters are "in-use." This field
should be null when the sentence is sent to an AIS.
NOTE 9 This is the UTC time that the "in-use" flag changed to the indicated
state. This field should be null when the sentence is sent to an AIS.
AIR – AIS interrogation request
This sentence supports ITU-R M.1371 message 15. It provides an
external application with the means to initiate a request for specific
ITU-R M.1371 messages from distant mobile or base AIS stations. A
single sentence can be used to request, as many as, two messages from
one AIS unit and one message from a second AIS unit. The message
types that can be requested are limited. The complete list of messages
that can be requested can be found within the message 15 description
in ITU-R M.1371. Improper requests may be ignored.
The external application initiates the interrogation. The external
application is responsible for assessing the success or failure of the
interrogation. After receiving this sentence, the AIS initiates a radio
broadcast (on the VHF Data Link) of a message 15 – Interrogation.
Appendix B - Digital Interface IEC 61162-1
Man_inst_AI80_r1 61
The success or failure of the interrogation broadcast is determined by
the external application's assessment of the combined reception of the
ABK-sentence and future VDM-sentences provided by the AIS via the
Presentation Interface. After receiving this AIR-sentence, the AIS
should broadcast a message 15 within 4 s, and the addressed AIS
should take no more than an additional 4 s to respond – a total of 8 s.
NOTE 1 Identifies the first distant AIS being interrogated. Two messages can
be requested from the first AIS.
NOTE 2 Examples of messages that may be requested from a distant mobile
AIS station include:
Message 3, Position Report,
Message 5, Ship Static and Voyage related data,
Message 9, Standard SAR Aircraft Position Report,
Message 18, Standard Class B Equipment Position Report,
Message 19, Extended Class B Equipment Position Report, and
Message 21, Aids-to-Navigation Report.
Examples of messages that may be requested from a distant AIS base
station include:
Message 4, Base Station Report,
Message 17, GNSS Broadcast Binary Message, (all available
corrections are requested),
Message 20, Data Link Management Message,
Message 22, Channel Management.
NOTE 3 This field is used to request a message that has been further sub-
divided into alternative data structures. When requesting messages
Simrad AI80 Installation Manual
62 Man_inst_AI80_r1
with alternative data structures, this message subsection identifier
must be provided, so that the correct sub-division of the message data
is provided. If the message structure is not sub-divided into different
structures, this field should be null.
NOTE 4 This identifies the second distant AIS being interrogated. Only one
message may be requested from the second AIS. The MMSI of the
second AIS may be the same MMSI as the first AIS. This technique
can be used to request a third message from station-1.
BBM – Broadcast binary message
This sentence supports generation of an ITU-R M.1371 Binary
Broadcast Message (message 8) or Safety Related Broadcast Message
(message 14). It provides an external application with a means to
broadcast data, as defined by the application only – not the AIS. This
message offers great flexibility for implementing system functions
that use the AIS like a digital broadcast device. After receiving this
sentence, the AIS initiates a VHF broadcast of either message 8 or 14
within 4 s. (Also, see the ABK-sentence.)
The success or failure of the broadcast confirmed through the use of
the "Addressed and binary Broadcast Acknowledgement (ABK)"
sentence formatter, and the processes that support the generation of an
ABK-sentence. The AIS is limited in the amount of encapsulated data
that can be sent in each slot and frame. If the length of the message
would exceed five slots, or the AIS broadcast would exceed the limit
of 20 RATDMA slot transmissions for the current frame, the AIS will
return an ABK-sentence
NOTE 1 The total number of IEC 61162-1 sentences needed to transfer the
contents of the binary message to the AIS. The first field specifies the
total number of sentences used for a message, minimum value 1. The
second field identifies the order of this sentence in the message,
minimum value 1. All sentences contain the same number of fields.
Successive sentences may use null fields for fields that do not change
– such as fields 4 and 5.
Appendix B - Digital Interface IEC 61162-1
Man_inst_AI80_r1 63
NOTE 2 The Sequential Message Identifier provides a message identification
number from 0 to 9 that is sequentially assigned as needed. Note that
this is only a sequential message identifier. This is used differently
than the "Message sequence identifier" of an ABM sentence. This
identifier is incremented for each new multi-sentence message. The
count resets to 0, after 9 is used. For the contents of a message 8 or 14
requiring multiple sentences, each sentence of the message contains
the same Sequential Message Identification number. This number is
used to link the separate sentences containing portions of the same
encapsulated data. This allows for the possibility that other sentences
might be interleaved with the message sentences that, taken
collectively, contain a single message 8 or 14. This number also links
a future ABK-sentence acknowledgement to the appropriate BBM-
sentence. (See ABK, NOTE 4.)
NOTE 3 The AIS channel that shall be used for the broadcast: 0 = no broadcast
channel preference, 1 = Broadcast on AIS channel A, 2 = Broadcast
on AIS channel B, 3 = Broadcast two copies of the message – one on
channel A and another sent on channel B.
NOTE 4 This is the content of the "binary data" parameter for ITU-R M.1371
message 8 or the "Safety related Text" parameter for message 14. The
first sentence may contain up to 58 "6-bit" symbols (348 bits). The
following sentences may contain up to 60 "6-bit" symbols (360 bits),
if fields 4 and 5 are unchanged from the first sentence and set to null.
The actual number of "6-bit" symbols in a sentence must be adjusted
so that the total number of characters in a sentence does not exceed
the "82-character" limit.
NOTE 5 To encapsulate, the number of binary bits must be a multiple of six. If
it is not, one to five "fill bits" are added. This parameter indicates the
number of bits that were added to the last 6-bit coded character. This
value shall be set to zero when no "fill bits" have been added. This
cannot be a null field.
LRI – Long-Range Interrogation
The long-range interrogation of the AIS is accomplished through the
use of two sentences. The pair of interrogation sentences, a LRI-
sentence followed by a LRF-sentence, provides the information
needed by an AIS to determine if it must construct and provide the
reply sentences (LRF, LR1, LR2, and LR3). The LRI-sentence
contains the information that the AIS needs in order to determine if
the reply sentences need to be constructed. The LRF-sentence
identifies the information that needs to be in the reply sentences.

together. The LRF sentence shall immediately follow the LRI
sentence and use the same sequence number. The requestor process
shall increment the sequence number each time a LRI/LRF pair is
created. The sequencing process shall continuously increment. After
"9" is used, the process shall begin again at "0". If the LRI and LRF
sequence numbers are different, the Long-range interrogation is not
valid.
NOTE 2 The control flag is a single character that qualifies the request for
information. The control flag affects the AIS unit's reply logic. The
control flag cannot be a null field. When the Control Flag is "0", the
AIS responds if either:
The AIS is within the geographic rectangle provided, and
The AIS has not responded to the requesting MMSI in the last 24
hours, and
The MMSI "destination" field is null.
or
The AIS unit's MMSI appears in the MMSI "destination" field in the
LRI sentence.
When the Control Flag is "1", the AIS responds if:
The AIS is within the geographic rectangle provided.
NOTE 3 This is the nine-digit number that uniquely identifies the specific AIS
that should respond. This field is null when the interrogation is for a
geographic region. When addressing a specific AIS, it is not necessary
to provide the geographic co-ordinates of the region.
NOTE 4 The geographic region being interrogated is a "rectangular" area
defined by the latitude and longitude of the north-east and south-west
corners. These fields should be null when interrogating a specific AIS.
(See note 2.)

LRF – Long Range Function
This sentence is used in both long-range interrogation requests and
long-range interrogation replies. The LRF-sentence is the second
sentence of the long-range interrogation request pair, LRI and LRF
(See the LRI-sentence.). The LRF-sentence is also the first sentence of
the long-range interrogation reply. The minimum reply consists of a
LRF-sentence followed by a LR1-sentence. The LR2-sentence and/or
the LR3-sentence follow the LR1-sentence, if information provided in
these sentences is requested in the interrogation. When the AIS creates
the LRF-sentence for the long-range interrogation reply, fields 1, 2, 3,
and 4 should remain as received in the interrogation; and field 5
(Function Reply Status) and a new checksum are added to the LRF
reply sentence.
NOTE 1 This is used to bind the contents of the LRI and LRF sentences
together. The LRF sentence shall immediately follow the LRI
sentence and use the same sequence number. The requestor process
shall increment the sequence number each time a LRI/LRF pair is
created. After 9 is used, the process shall begin again from 0. The
Long-range interrogation is not valid if the LRI and LRF sequence
numbers are different.
NOTE 2 The Function request field uses alphabetic characters based upon IMO
Resolution A.851(20) to request specific information items. Specific
information items are requested by including their function
identification character in this string of characters. The order in which
the characters appear in the string is not important. All characters are
upper case. Information items will not be provided if they are not
specifically requested – even if available to the AIS. The IMO
Resolution defines the use of all characters from A to Z, but not all of
the defined information is available from the AIS. The following is a
list of the function identification characters with the information they
request:
A = Ship's: name, call sign, and IMO number
B = Date and time of message composition
C = Position
Simrad AI80 Installation Manual

E = Course over ground
F = Speed over ground
I = Destination and Estimated Time of Arrival (ETA)
O = Draught
P = Ship/Cargo
U = Ship's: length, breadth, type
W = Persons on board
NOTE 3 The "Function Reply Status" field provides the status characters for
the "Function Request" information. When a long-range interrogation
request is originated, the "Function Reply Status" field should be null.
The "Function Reply Status" characters are organised in the same
order as the corresponding function identification characters in the
"Function Request" field. The following is a list of the "Function
Reply Status" characters with the status they represent:
2 = Information available and provided in the following LR1, LR2, or
LR3 sentence,
3 = Information not available from AIS unit,
4 = Information is available but not provided (i.e. restricted access
determined by ship's master),
LR1 – Long-range Reply with destination
for function request "A"
The LR1-sentence identifies the destination for the reply and contains
the information requested by the "A" function identification character.
(See the LRF-sentence.)
NOTE 1 The three fields, sequence number, MMSI of responder, and MMSI of
requestor are always provided.

SSD – Ship Static Data
This sentence is used to enter static parameters into a shipboard AIS.
The parameters in this sentence support a number of the ITU-R
M.1371 messages.
NOTE 1 Ship call sign. A null field indicates that the previously entered call
sign is unchanged. The string of characters "@@@@@@@" are used
to indicate that the call sign is not available.
NOTE 2 The characters that can be used in the name are listed in the ITU-R
M.1371, table 14 (6-bit ASCII). Some of the acceptable characters in
this 6-bit ASCII table are reserved characters under IEC 61162-1.
They must be represented using the "^-method" (See IEC 61162-1,
section 5.1.3.). A null field indicates that the previously entered name
is unchanged. The string of characters
"@@@@@@@@@@@@@@@@@@@@" are used to indicate
that the ship's name is not available.
NOTE 3 These are the four dimensions from the bow, stern, port beam, and
starboard beam to the horizontal reference point on the ship for which
the current "position reports" are valid. The sum of A + B is the length
of the ship in metres, and the sum of C + D is the width of the ship in
metres (See ITU-R M.1371, message 5, "Reference Point for reported
position and Dimensions of Ship."). If the reference point of "reported
position" is not available, but the dimensions of the ship are available:
A = C = 0 and B > 0 and D > 0. If neither the reference point for the
reported position nor the dimensions of the ship are available: A = B =
C = D = 0 (default). Use of a null field for A, B, C, and/or D indicates
that the previously entered dimension for that parameter is unchanged.
In many cases, the ship's reference point for "reported position" will
be the location of the positioning antenna.
NOTE 4 The DTE indicator is an abbreviation for Data Terminal Equipment
indicator. The purpose of the DTE indicator is to inform distant
Simrad AI80 Installation Manual
70 Man_inst_AI80_r1
receiving applications that, if set to "available" the transmitting station
conforms, at least, to the minimum keyboard and display
requirements. The DTE indicator is only used as information provided
to the application layer – indicating that the transmitting station is
available for communications. On the transmitting side, the DTE
indicator may be set by an external application using this sentence.
DTE indicator flag values are:
0 = Keyboard and display are a standard configuration, and
communication is supported.
1 = Keyboard and display are either unknown or unable to support
communication (default setting).
NOTE 5 The source identifier contains the "Talker ID" of the equipment at this
location. The AIS may use the "Talker ID" to identify multiple
sources of position data and to detect a change to the reference point
on the ship.
VDM – VHF Data-link Message
This sentence is used to transfer the entire contents of a received AIS
message packet, as defined in ITU-R M.1371 and as received on the
VHF Data Link (VDL), using the "6-bit" field type. The structure
provides for the transfer of long binary messages by using multiple
sentences.
NOTE 1 The length of an ITU-R M.1371 message may be long and may
require the use of multiple sentences. The first field specifies the total
number of sentences used for a message, minimum value 1. The
second field identifies the order of this sentence in the message,
minimum value 1. These cannot be null fields.
NOTE 2 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 message 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
Appendix B - Digital Interface IEC 61162-1
Man_inst_AI80_r1 71
message. This allows for the possibility that other sentences might be
interleaved with the message sentences that, taken collectively,
contain a single message. This field shall be a null field when
messages fit into one sentence.
NOTE 3 The AIS message reception channel is indicated as either "A" or "B."
This channel indication is relative to the operating conditions of the
AIS when the packet is received. This field shall be null when the
channel identification is not provided. The VHF channel numbers for
channels "A" and "B" are obtained by using an ACA-sentence "query"
of the AIS.
NOTE 4 The maximum string length of encapsulation is limited such that the
total number of sentence characters does not exceed 82. This field
supports a maximum of 62 valid characters for a message transferred
using multiple sentences, and 63 valid characters for a message using
a single sentence.
NOTE 5 To encapsulate, the number of binary bits must be a multiple of six. If
it is not, one to five "fill bits" are added. This parameter indicates the
number of bits that were added to the last 6-bit coded character. This
value shall be set to zero when no "fill bits" have been added. This
cannot be a null field.
VDO – VHF Data-link Own-vessel message
This sentence is used to provide the information assembled for
broadcast by the AIS. It uses the six-bit field type for encapsulation.
The sentence uses the same structure as the VDM sentence formatter.
NOTE 1 The length of an ITU-R M.1371 message may be long and may
require the use of multiple sentences. The first field specifies the total
number of sentences used for a message, minimum value 1. The
second field identifies the order of this sentence in the message,
minimum value 1. These cannot be null fields.
NOTE 2 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

72 Man_inst_AI80_r1
used. For a message 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
message. This allows for the possibility that other sentences might be
interleaved with the message sentences that, taken collectively,
contain a single message. This field shall be a null field when a
message fits into one sentence.
NOTE 3 This is the channel used to broadcast the AIS message. The AIS
channel field, set to either "A" or "B", indicates that the message was
broadcast. If the message is not broadcast, the "AIS Channel" field
shall be null. The VHF channel numbers for channels "A" and "B" are
obtained by using an ACA-sentence "query" of the AIS.
NOTE 4 The maximum string length of encapsulation is limited such that the
total number of sentence characters does not exceed 82. This field
supports a maximum of 62 valid characters for a message transferred
using multiple sentences, and 63 valid characters for a message using
a single sentence.
NOTE 5 To encapsulate, the number of binary bits must be a multiple of six. If
it is not, one to five "fill bits" are added. This parameter indicates the
number of bits that were added to the last 6-bit coded character. This
value shall be set to zero when no "fill bits" have been added. This
cannot be a null field.
VSD – Voyage Static Data
This sentence is used to enter information about a ship's voyage. This
information remains relatively static during the voyage. However, the
information will frequently change from voyage to voyage. The
parameters in this sentence support a number of the ITU-R M.1371
messages.
Appendix B - Digital Interface IEC 61162-1
Man_inst_AI80_r1 73
NOTE 1 Type of ship and cargo category are defined in ITU-R M.1371. The
description of ship and cargo are indicated by a number. The values
are defined in ITU-R M.1371, message 5. A null field indicates that
this is unchanged.
NOTE 2 Draught is reported in the range of 0 to 25,5 metres. The value 0 = not
available (default), and the value 25,5 indicates that the draught is
25,5 metres or more. Only values from 0 to 25,5 shall be accepted by
the AIS. A null field indicates that this is unchanged.
NOTE 3 Number of persons on-board includes the crew. The value 0 = not
available (default). The value 8191 = 8191 or more people. Only
values from 0 to 8191 shall be accepted by the AIS. A null field
indicates that this is unchanged.
NOTE 4 The characters that can be used in the destination are listed in the
ITU-R M.1371, table 14 (6-bit ASCII). Some of the acceptable
characters in this 6-bit ASCII table are reserved characters under IEC
61162-1. They must be represented using the "^-method" (See IEC
61162-1, section 5.1.3.). A null field indicates that the previously
entered destination is unchanged. The string of characters
"@@@@@@@@@@@@@@@@@@@@" are used to indicate
that the ship's destination is not available.
NOTE 5 The UTC time of arrival field follows the "TIME" field type described
in table 6 (IEC 61162-1). The two fixed digits of seconds are not
broadcast by the AIS and should be set to "00". The optional decimal
point and associated decimal fraction shall not be provided. The
resulting time is a number with six fixed digits, "hhmm00". Leading
zeros are always included for the hours and minutes. If the hour of
arrival is not available, "hh" shall be set to 24. If the minute of arrival
is not available, "mm" shall be set to 60. A null field indicates that this
is unchanged.
NOTE 6 The day and month of arrival are in UTC. The day is a two-digit fixed
number requiring leading zeros. The month is a two-digit fixed
number requiring leading zeros. If the day of arrival is not available,
"00" shall be the number for day. If the month of arrival is not
available, "00" shall be the number for the month. A null field
indicates that this is unchanged.
NOTE 7 The Navigational status is indicated using the following values, a null
field indicates the status is unchanged (ref. ITU-R M.1371, Message
1, Navigational status parameter):
0 = under way using engine
1 = at anchor
2 = not under command
3 = restricted manoeuvrability

7 = engaged in fishing
8 = under way sailing
9 = reserved for High Speed Craft
10 = reserved for Wing In Ground
11 to 14 = reserved for future use
15 = not defined (default)
NOTE 8 Definition of values 1 to 15 provided by a competent regional
authority. Value shall be set to zero (0), if not used for any regional
application. Regional applications shall not use zero. A null field

NOTE 1 Expected error in metres due to bias, with noise = 0.
NOTE 2 Satellite ID numbers. To avoid possible confusion caused by
repetition of satellite ID numbers when using multiple satellite
systems, the following convention has been adopted:
GPS satellites are identified by their PRN numbers, which range from
1 to 32.
The WAAS system has reserved numbers 33 – 64 to identify its
satellites.
The numbers 65 – 96 are reserved for GLONASS satellites.
GLONASS satellites are identified by 64+ satellite slot numbers. The
slot numbers are 1 through 24 for the full GLONASS constellation of
24 satellites, thus giving a range of 65 through 88. The numbers 89
through 96 are available if slot numbers above 24 are allocated to on-
orbit spares.
Only Expected error in latitude and Expected error in longitude is
required and used by the AIS.
GGA – Global positioning system (GPS) fix

Man_inst_AI80_r1 79
GNS – GNSS fix data
Fix data for single or combined satellite navigation systems (GNSS).
This sentence provides fix data for GPS, GLONASS, possible future
satellite systems and systems combining these. This sentence could be
used with the talker identification of GP for GPS, GL for GLONASS,
GN for GNSS combined systems, as well as future identifiers. Some
fields may be null fields for certain applications, as described below.
If a GNSS receiver is capable simultaneously of producing a position
using combined satellite systems, as well as a position using only one
of the satellite systems, then separate $GPGNS, $GLGNS, etc.
messages may be used to report the data calculated from the
individual systems.
If a GNSS receiver is set up to use more than one satellite system, but
for some reason one or more of the systems are not available, then it
may continue to report the positions using $GNGNS, and use the
mode indicator to show which satellite systems are being used.
NOTE 1 Mode Indicator. A variable length valid character field type with the
first two characters currently defined. The first character indicates the
use of GPS satellites, the second character indicates the use of
GLONASS satellites. If another satellite system is added to the
standard, the mode indicator will be extended to three characters; new
satellite systems shall always be added to the right, so the order of
characters in the Mode Indicator is: GPS, GLONASS, other satellite
systems.
The characters shall take one of the following values:
N = No fix. Satellite system not used in position fix, or fix not valid.
A = Autonomous.Satellite system used in non-differential mode in
position fix.
Simrad AI80 Installation Manual
80 Man_inst_AI80_r1
D = Differential. Satellite system used in differential mode in position
fix.
P = Precise. Satellite system used in precision mode. Precision mode
is defined as: no deliberate degradation (such as Selective
Availability), and higher resolution code (P-code) is used to compute
position fix.
R = Real Time Kinematic. Satellite system used in RTK mode with
fixed integers.
F = Float RTK. Satellite system used in real time kinematic mode with
floating integers.
E = Estimated (dead reckoning) Mode.
M = Manual Input Mode.
S = Simulator Mode.
The Mode indicator shall not be a null field.
NOTE 2 Age of differential data and Differential reference station ID
When the talker is GN and more than one of the satellite systems are
used in differential mode, then the "Age of differential data" and
"Differential reference station ID" fields shall be null. In this case, the
"Age of differential data" and "Differential reference station ID" fields
shall be provided in following GNS messages with talker IDs of
GP,GL, etc. These following GNS messages shall have the latitude,
N/S, longitude, E/W, altitude, geoidal separation, mode and HDOP
fields null. This indicates to the listener that the field is supporting a
previous $GNGNS message with the same time tag. The "Number of
satellites" field may be used in these following messages to denote the
number of satellites used from that satellite system.
Example: A combined GPS/GLONASS receiver using only GPS
differential corrections has the following GNS sentence sent:
$GNGNS,122310.2,3722.425671,N,12258.856215,W,DA,14,0.9,
1005.543,6.5,5.2,23*59<CR><LF>
Example: A combined GPS/GLONASS receiver using both GPS
differential corrections and GLONASS differential corrections may
have the following three GNS sentences sent in a group:
$GNGNS,122310.2,3722.425671,N,12258.856215,W,DD,14,0.9,1005

b) Age of Differential Data
For GPS differential data: This value is the average of the most
recent differential corrections in use. When only RTCM SC104 Type
1 corrections are used, the age is that of the most recent Type 1
correction. When RTCM SC104 Type 9 corrections are used solely, or
in combination with Type 1 corrections, the age is the average of the
most recent corrections for the satellites used. Null field when
Differential GPS is not used.
For GLONASS differential data: This value is the average age
of the most recent differential corrections in use. When only RTCM
SC104 Type 31 corrections are used, the age is that of the most recent
Type 31 correction. When RTCM SC104 Type 34 corrections are
used solely, or in combination with Type 31 corrections, the age is the
average of the most recent corrections for the satellites used. Null
field when differential GLONASS is not used.
NOTE 3 HDOP calculated using all the satellites (GPS, GLONASS and any
future satellites) used in computing the solution reported in each GNS
sentence.
NOTE 4 Geoidal separation is the difference between the earth ellipsoid
surface and mean-sea-level (geoid) surface defined by the reference
datum used in the position solution, "-" = mean-sea-level surface
below ellipsoid surface. The reference datum may be specified in the
DTM sentence.
UTC of position, Latitude, Longitude and Mode indicator, are the only
fields used by the AIS.
HDT – Heading true
IMO Resolutions A.424 and A.821. Actual vessel heading in degrees
true produced by any device or system producing true heading.

B = bottom tracking log
M = manually entered
W = water referenced
R = radar tracking (of fixed target)
P = positioning system ground reference.
Heading, Heading status, Vessel course, Vessel speed and Speed

USING OPTIONAL MKD
10.1 Security settings optional MKD
To avoid unauthorised input of data in the menus accessed from the
Main menu, the AI80 system should be set up with security codes and
different access levels.
3 different access levels may be defined:
Level 0: No security code required
Level 1: Access controlled by L1 PIN Code or L2 PIN Code
Level 2: Access controlled by L2 PIN Code
Access levels for the different menus are defined in the Security
submenu, activated from the Menu page.
Setting the security codes
When using the external, optional MKD the default security code
delivered with the Mobile Unit is “AIS” as for both Level 1 and Level
2. These security codes should be changed when the system is
configured for the first time. Use the following procedure to change
the security codes:

5. Continue entering security levels for the remaining parameter
groups.
Note ! To ease the operation of the system, all parameters that have to be
changed during normal operation should be set to Level 0.
Note ! Once authenticated with L1 or L2 PIN code, the authentication is
valid until the View page has been displayed for 5 seconds. To protect
the AI80 security systems, the MKD returns to the View page when not
used for 15 minutes. In high security applications we recommend
manually returning to the View page when a change that required
authentication is completed.
