Safety Summary
WARNING: ENSURE THAT THE M-2 AIS HAS BEEN CORRECTLY
INSTALLED IN ACCORDANCE WITH IMO GUIDELINES AND THE
SUPPLIED INSTALLATION MANUAL BEFORE POWERING ON THE
SYSTEM.
WARNING: The M-2 has no ON/OFF or power switch. It will automatically start
operation within 2 minutes of applying power to the transponder unit.
WARNING: Transponder chassis can become hot during extended periods of
operation. Avoid touching this when the transponder is operating. The plastic
dust cover must be fixed in place before setting the equipment to work.
WARNING: Do not touch the VHF antenna or connecting cable when the
transponder is in operation.
WARNING: Unauthorised opening of the transponder access covers may
invalidate the manufacturer’s warranty.
WARNING: Avoid using chemical solvents to clean the Display or transponder
dust cover as they can damage the casing material.
WARNING: The use and operation of an AIS transponder is legislated and
forms a part of the ship’s mandatory navigation equipment under SOLAS
regulations. It is therefore necessary that the installation is certified
(commissioned) and that certain information has to be available before full
operation of the transponder can take place. The ship’s IMO and MMSI
numbers and other important information must be entered as part of the
installation and commissioning procedure, and before the equipment is used at
sea.
WARNING: This product is sold or provided as merely an aid to navigation. It is
the responsibility of the user to exercise discretion and proper navigational and
seamanship skills.
WARNING: NOT ALL SHIPS CARRY AIS. The Officer of the Watch (OOW)
should always be aware that other ships and, in particular, leisure craft, fishing
boats and warships, and in some cases coastal shore stations (including
Vessel Traffic Systems (VTS) centres), may not be fitted with AIS. The OOW
should always be aware that AIS fitted on other ships as a mandatory carriage
requirement may, under certain circumstances, be switched off based on the
Master’s professional judgement.
WARNING: The use of a Megger (High Voltage Insulation Tester) may damage
the equipment and therefore should not be used.
WARNING: Do not operate the equipment when persons are closer than 3
metres from the antenna. If any person (e.g. the operator) must be closer, then
a grounded RF shield should be interposed between that person and the
antenna.
AIS Operation Licensing
IMPORTANT: Operation of the AIS Transponder is covered by international
radio regulations and therefore the ship must possess a valid ship’s radio
licence. The AIS equipment must be correctly registered (Call Sign and MMSI
number). Operation of AIS equipment without a valid MMSI number
contravenes international radio regulations and must be avoided. Please
contact the relevant authority in your country for further information regarding
ship’s radio licensing requirements.
Disclaimer
Information contained in this manual is correct at time of going to print but is
liable to change without notice. McMurdo Limited disclaims any liability for
consequences arising from omissions or inaccuracies in the manuals and
documentation provided with this product.
Equipment may be upgraded and features added at any time; however, the
basic principles given in this document will remain unchanged.

2 Issue 1 M-2 AIS Operation
Product Definition
AIS overview
The Automatic Identification System (AIS) system provides for communication,
navigation and s urveillance capabilities for vessels and for fixed coast radio
stations. The AIS transponder offers high-speed automated communication from
ship to ship and ship to shore of vessel-, voyage- and safety-related information.
Own vessel navigational data is automatically transmitted directly to surrounding
vessels and shore based VTS systems utilising marine VHF channels. The AIS
gives mariners the ability to vie w at a glance the status of AIS equipped vessels
and aids to navigation around them and provides access to a host of detailed
navigation information.
M-2 AIS Operation Issue 1 3
The M-2 is primarily designed for use as a shipborne AIS mobile station, and
comprises of two main parts:
Transponder
The M-2 AIS transponder has an integral Global Navigation Satellite System
(GNSS) engine used for timing, one radio transmitter, three radio receivers and
a computer unit. The AIS equipment should be interfaced to the vessel’s primary
GNSS navigation receiver, connected to a marine antenna and be interfaced to
the vessel’s gyro compass.
As appropriate to the class and use of vessel, there is provision for additional
interface connections : Rate of Turn (ROT) indicator, bottom track speed log,
differential beacon Global Positioning System (GPS) receiver, Electronic Chart
Display Information System (ECDIS) or Automatic Radar Plotting Aid (ARPA)
system, Pilot Plug and Long Range port.
Display
The Display is used to input vessel details, configure the system and to display
AIS target information.
An IMO pilot plug socket box may be attached to a socket on the rear of the
display or connected directly to the transponder.
AIS in use
The AIS Transponder transmits information which is separated into three
groups:
Static data - Vessel name, type, length and breadth, MMSI and IMO numbers
and GNSS antenna location.
Dynamic data – Position, accuracy and integrity of the position, time, course
and speed over ground and navigational status.
Voyage data – Cargo, draught, port of destination and estimated time of arrival.
In addition, the AIS can transmit and receive Safety Messages . These may
include navigation safety information, warnings of floating objects, collisions,
meteorological situations, etc.
Differential correction information for GNSS can be processed by the AIS,
increasing the accuracy of positional information and hence the safety of the
vessel. Differential correction information can also be provided by connection of
a supplementary differential beacon differential receiver.
4 Issue 1 M-2 AIS Operation
M-2 Key AIS Functions
- Automatic identification of other AIS equipped stations.
- Self-organising control of access to the radio channels.
- Reception of data from other vessels and coast radio stations.
- Transmission of own vessel data for use by other vessels and coast stations.
- Storage of static data intended for automatic transmission via the radio
channels.
- Output of data received via the radio channels from other AIS targets for
presentation on the Display or other visual display equipment.
- Determination of the position and motion of own vessel if the external GNSS
receiver fails , by utilising the internal GNSS receiver.
- Application of GNSS differential corrections using information supplied from a
supplementary differential beacon receiver.
- Application of GNSS differential corrections using information received from a
controlling station via Message 17 over the AIS VHF Data Link (VDL) channel.
- Display of bearings and distances to the vessels, calculated from their co-
ordinates, obtained via the AIS VDL channels.
Operation
Please read all the warning notices at the front of this manual before applying
power to the AIS Transponder and setting the equipment to work.
Activation
It is recommended that AIS should not normally be powered down and should
always remain in operation continuously. However, based on the Master’s
professional judgement, either transmissions may be inhibited by selecting
‘Silent mode’ or the AIS may be powered down entirely if continuous operation
might compromise the ship’s safety or security. This might be necessary in
waters where pirates or armed robbers are known to operate or during some
cargo handling or maintenance operations.
Actions of this nature should always be recorded in the ship’s logbook.
Reactivation of the AIS should take place as soon as the reason for deactivation
has passed.
Compliance
The M-2 AIS complies with international standards and is type approved in
accordance with the European Marine Equipment Directive. The EU Declaration
of Conformity, shown on the rear pages, lists the relevant approval standards .
Details of other Worldwide type approvals are listed on the McMurdo website
www.mcmurdo.co.uk

M-2 Product description
Key features
• Shipborne Class A AIS
• Versatile Keyboard and Display Unit
• Clear presentation of targets as graphics and text
• Integral 16 channel Space-Based Augmentation System (SBAS)
-enabled GPS receiver
• Differential GNSS (DGNSS) correction
• Interfaces to ECS, ECDIS, ARPA
• Pilot plug connection
• Integral ship’s cable termination board
• Four sensor interfaces
• Long Range port
The M-2 gives a clear indication of identity, proximity and bearing of surrounding
AIS targets. By providing this information in both graphic and text formats the
need for ‘bridge to bridge’ radio voice contact between vessels is much reduced.
AIS targets are unaffected by radar shadow effects and remain visible even
when targets may be lost to the vessel’s radar.
Own vessel static and voyage related information is broadcast automatically
every six minutes. Depending on the speed the vessel is making, dynamic
factors (speed, course, heading and rate of turn) are transmitted at intervals of
between two and twelve seconds or every three minutes when moored.
M-2 Display controller and Transponder unit
6 Issue 1 M-2 AIS Operation
The M-2 Display unit features a large, high contrast, backlit Liquid Crystal
Display (LCD) graphic display. AIS target information may be displayed as an
ordered list or plotted on a latitude/longitude grid overlay. The clear graphical
target presentation gives the officer of the watch a clear overview and best
visual understanding of a developing hazard to navigation situation. The AIS
target list has a split screen view; detailed AIS target information is clearly
displayed in the lower section. Menu ‘Soft Keys’ provide for an intuitive user
interface and give direct and easy access to all aspects of system operation.
Entry of alphanumeric text information is both easy and straightforward using
the on-screen ‘pop-up’ keyboard together with an intuitive four way navigation
pad key. Standard text phrases may be edited and re-used when composing
text based safety messages or when updating own vessel voyage, route, and
destination details.
Comprehensive interfaces are provided for the connection of the vessel’s
primary navigation sensors, Integrated Bridge System (IBS) or Electronic Chart
System (ECS).

Quick Start - setting to work
WARNING: The M-2 has no ON/OFF switch. It will automatically start operation
within 2 minutes of applying power to the transponder unit.
Caution: Read the warning notices at the front of this manual before powering
up the AIS Transponder.
When setting the M-2 to work, always review your vessel’s voyage related
information and update as required.
Starting the M-2
Apply the power source to the Transponder. This procedure will depend on the
vessel’s actual installation arrangements but would generally involve closing a
switch panel circuit breaker or switching on the AC / DC rectifier power unit (if
fitted).
After a short delay the Display Alert indication lamp (red LED) will start to flash
and shortly after that the Display start up welcome screen will be displayed.
Review and update your vessel’s voyage related information.
Check that the vessel’s navigation sensors are providing valid navigation
information.
Take particular notice that the heading information is in correct alignment with
the vessel’s master steering compass.
Consult the following sections for detailed system operation information.

14 Issue 1 M-2 AIS Operation
Password access control
The M-2 AIS unit has three levels of access control - each of which is protected
by its own password. The three levels are:
User level protects voyage-related data such as that displayed on the
Voyage mode: Own voyage page.
Operator level protects operational data such as the channel regions shown
on the Setup mode: Channel regions page.
Service level this level of access is available only to authorised service
agents and protects ship's static data (such as the MMSI and
IMO numbers) which must be programmed into the unit.
The user and operator passwords are optional. If either of them is not required
(permitting any user to change the voyage or operating data) then they may be
set to the special password "NONE" (which is the default setting). It is
recommended that the operator password is set, and that the user password is
not used.
If a user password is configured, but the operator password is left as "NONE"
then the user password will not be effective since the system will grant operator-
level access without requiring a password.
Each page protected by a password has an Edit softkey - for instance the Own
Voyage page displays the Edit VOYAGE DATA softkey whilst the Channel
Regions page displays the Edit CHANNEL REGIONS softkey. When the Edit
softkey is activated, the user is prompted to enter the corresponding password.
Press the 'Enter' button to bring up the on-screen keyboard, and then enter
the appropriate password into the top field. Then activate the Verify
PASSWORD softkey in order to check the password. If the password is correct,
you will be granted access to the preceding page.
When the password is set to "NONE" then the user is permitted to edit the
corresponding page immediately without being prompted to enter the password.
M-2 AIS Operation Issue 1 15
Changing passwords
Any password can be changed by using the Edit STATIC DATA softkey on the
Setup mode: Ship's static data page. Since the static data is protected by the
Service password, this softkey always causes the password prompt to be
displayed.
To change any password, select the desired password entry page (the Change
XXXXX PASSWORD softkey cycles through these pages) and enter the current
password, then enter the new password in each of the two fields, Change
password and Confirm password. Finally, press the Verify PASSWORD
softkey. Provided that the two new password entries are identical, an
acknowledgement is displayed on screen and the new password takes
immediate effect.
16 Issue 1 M-2 AIS Operation
If the new passwords are not identical, a warning message is displayed. The
original password remains valid.
Resetting lost passwords
If the user password is forgotten, the operator or service passwords may be
entered into the User password field instead, in order to allow the user
password to be re-set. Similarly, the operator password can be reset by entering
the service password as the Operator password.
The service password cannot be overridden. If this password is changed and
then forgotten, then only a Service Agent can reset the AIS to restore the default
passwords.

Alarm mode: All events log
This page lists all the alarm, information and security events, with the most
recent events at the top.
Acknowledging alarms
Normally, alarms are acknowledged by using the ENTER button to clear the
popup message box, which acknowledges the alarm. Unacknowledged alarms
may also be acknowledged by moving the cursor down the list to select the
unacknowledged alarm - and then using the Ack Alarm softkey.
Event codes
Codes are divided into two categories – alarm codes and log entries. Alarm
codes relate to generated alarms; event codes, distinguished by a dash (-),
relate to log entries only.
Alarm codes
Each alarm is preceded by a 4-character ID code.
The first character indicates the state of the alarm and may be 'A' for activated,
'V' for inactivated or 'C' for current.
A current alarm is an alarm which is ongoing at the present time. (Current
alarms are also shown on the current alarms page.)
An activated alarm is an alarm that occurred at the time indicated in the first
column of the alarm log, and has subsequently cleared. The ‘A’ indicates that
the record refers to the time when the alarm occurred.

M-2 AIS Operation Issue 1 31
An inactivated alarm is an alarm which has cleared at the time indicated. This is
the second entry for a particular alarm – the times when it occurred and when it
cleared are recorded separately. The ‘V’ indicates that the record refers to the
time when the alarm cleared.
The second character indicates whether the alarm has been acknowledged or
not - 'A' indicates that it has been acknowledged and 'V' that it has not.
The two numeric digits are a unique code for each alarm type.
Log entry codes
Log entry codes are of two types – Security and Text. Neither event requires
acknowledgment.
Security codes are explained in the Security Log section.
Text codes denote entries in the log which may be used for fault determination
and servicing. Each text entry is preceded by a 4-character ID code. The first
character is always an 'T' for text entries, and the second character is always '-'
to indicate that acknowledgement is not required. The two numeric digits are a
unique identifier in accordance with AIS specifications.

Alarm mode: Security log
This page lists the events stored in the security log. The security log stores any
event which results in the AIS transmitter being disabled for more than 15
minutes. The events in this log are retained permanently and are only deleted
when the log has reached its maximum size of 30 events.
Security event codes
Each security event is preceded by a 4-character ID code. The first character is
always an 'S' for security events, and the second character is always '-' to
indicate that acknowledgement is not required. The two numeric digits are an
index value indicating the relative position in the log of each entry.
Security event types
Tx silent - this indicates that the transponder has been placed into a silent mode
as a result of being in a location where regional channel management has
specified that the transponder should not transmit.
Tx quiet - this indicates that the transmitter has been disabled as a result of an
operator command. This is a special function that is not available on all units.
Power off - this indicates that the M-2 transponder was switched off.
Tx alarm - there has been a persistent fault with the transmitter.
VSWR alm - there has been a persistent fault with the antenna. This has not
stopped the transponder from transmitting, but performance may have
been impaired

Security event durations
Each security event covers a period of time indicated by the "duration" shown on
screen. The time at which the event started (eg when the transponder was
switched off) is given by the time and date displayed. The duration for which the
event persisted (eg for how long the transponder was switched off) is given by
the duration in hours and minutes. The time at which the event finished (eg
when the transponder was switched back on) can be determined by adding the
duration to the start time/date.

Channel Regions
Used to set geographic areas which have specific AIS channels requirements.
When entering a new channel region, the new values may be entered on any
one of the channel region pages (including region 0 - the "High Seas" region).
Once the new information has been saved and confirmed (by using both the
"Save CHANNEL REGION" and "Confirm CHANNEL REGION" softkeys) then
the new region will be allocated to a particular page according to the following
rules:
If the geographic co-ordinates match or overlap with an existing region
then the old region will be replaced by the new one.
Otherwise, the new region is stored in page 1 and the other pages
are moved downwards. If all the pages are used, the oldest region is
deleted.

Maintenance and Servicing
Preventative Maintenance
The UAIS transponder system is an essential part of the ship’s navigation
system and is a vital component for the safety of the ship and its crew. It is
therefore very important to maintain the system and its installation to a very high
standard. The design of the AIS transponder ensures that maintenance can be
kept to a minimum.
Display and transponder unit
To optimise performance ensure they are kept clean and grease-free. Use a
clean damp cloth, or for heavier deposits use a clean, damp cloth and a mild
solution of dish washing detergent and water. Do not use any spirit or alcohol
based solvents, gasoline or oils.
Electrical Connections
Periodically check the electrical connections; ensure that no cables are frayed or
worn, and that all connections are tight and sound.
Repair and Service
With the exception of the fuse located under the transponder cover, there are no
user serviceable parts.
Removal of the metal inspection covers other than by an Authorised Service
Technician will void warranty. If having followed the Troubleshooting Guide the
AIS is still inoperable, please call your local Service Centre.
Spare Parts
Use only manufacturer’s genuine spare parts. No liability can be accepted for
equipment failure due to incorrect replacement parts being used.

M-2 AIS Operation Issue 1 49
Alarm Messages
The transponder may generate various alarm and information messages that
appear as pop-ups on the display. Messages categorised as "alarms" also
cause the transponder to generate an audible or visual alarm (depending on the
installation) and must be acknowledged on the display unit in order to clear the
alarm. Messages categorised as "information" do not require any specific action
and the pop-up window on the display unit will automatically disappear after 30
seconds. All these messages are stored in the "alarms list" that can be viewed
on the "Alarm mode: Alarms log" page on the M-2 display unit.
The messages which may appear are listed in numeric order.
Tx malfunction (Alarm 01)
This indicates that there is a problem with the transponder. The occasional
occurrence of this alarm may be caused by transient conditions and does not
necessarily indicate a permanent problem. However, if this alarm occurs on a
regular basis you should take action to have your installation checked by an
authorised service agent.
Antenna VSWR exceeds limits (Alarm 02)
This indicates that there is a problem with the antenna. The transponder is likely
to be still operational, although its performance may be impaired. The
occasional occurrence of this alarm may be caused by transient conditions and
does not necessarily indicate a permanent problem. However, if this alarm
continues to occur you should take action to have your installation checked by
an authorised service agent.
Rx Channel 1 malfunction (Alarm 03)
Rx Channel 2 malfunction (Alarm 04)
Rx Channel 70 malfunction (Alarm 05)
These messages indicate that there is a possible problem with the receiver for
AIS channel A, AIS channel B or the DSC channel 70 respectively. Again, the
occasional occurrence of this message should not be cause for alarm, but the
regular occurrence of these messages is likely to indicate a permanent problem
which should be investigated by an authorised service agent.
Transceiver connection lost (Alarm 08)
This message indicates that the M-2 display unit can no longer communicate
with the M-2 transponder. This may indicate a problem with the connections, or
may indicate that the transponder is no longer operating correctly. This fault
should be investigated immediately. It is important to note that there is a safety
timer in the transponder which causes it to shut down automatically if the
transmitter should remain on for too long. In this event, the transponder will shut
down and this alarm will be raised by the display unit. The situation can be
resolved by disconnecting the power from the transponder for a short time and
then re-connecting it again.
50 Issue 1 M-2 AIS Operation
External EPFS lost (Alarm 25)
This message indicates that the transponder is no longer receiving data from the
vessel's on-board GPS system. This message should be investigated
immediately.
No position sensor in use (Alarm 26)
This message indicates that the M-2 transponder is unable to obtain a location
fix from either the internal GPS module or from the ship's own GNSS system.
This message may occur during the first few minutes of operation while the
transponder waits to obtain its location, and may safely be ignored during this
time. If the message occurs at any other time, it indicates a possible problem
with the GNSS antennae or wiring and should be investigated immediately
No valid SOG information (Alarm 29)
No valid COG information (Alarm 30)
Heading lost/invalid (Alarm 32)
No valid ROT information (Alarm 35)
These messages indicate that information from various sensors - ie the Speed
over Ground, Course over Ground, heading and Rate of Turn respectively - are
not available. In a full installation it is expected that all this information will be
available permanently and the display of one or more of these messages is an
indication that there may be problems either with the other sensors or with the
connections between the sensors and the M-2 transponder unit. Such
messages should be investigated immediately.
UTC clock lost (Information 07)
This message indicates that internal GPS module within the M-2 transponder is
unable to obtain a valid time signal. If this message appears on a regular basis it
may indicate a problem with the GNSS antenna connection, but it is possible for
this message to occur temporarily in certain locations or in extreme weather
conditions where the GNSS module is unable to receive transmissions from a
sufficient number of satellites.
External DGNSS in use (Information 21)
External GNSS in use (Information 22)
Internal DGNSS in use (beacon) (Information 23)
Internal DGNSS in use (msg 17) (Information 24)
Internal GNSS in use (Information 25)
These messages indicate which source of GNSS information is currently in use
by the transponder. The external GNSS information from the ship's main on-
board systems may or may not be augmented by differential correction
information - in which case the messages show "DGNSS" rather than "GNSS".
When the external GNSS signals are not available, the M-2 transponder uses
GNSS information from its own internal GNSS module and the message
changes to "Internal GNSS". This information may be augmented by the receipt
of differential correction data from a beacon receiver or by VHF transmissions
from a base station - in which case the status message shows "DGNSS" and
M-2 AIS Operation Issue 1 51
"beacon" or "msg 17" respectively to indicate the source of the differential data
being used.
External SOG/COG in use (Information 27)
Internal SOG/COG in use (Information 28)
These messages indicate whether Speed over Ground and Course over Ground
are being supplied by the external sensors or are being calculated from the
internal GNSS module.
Heading valid (Information 31)
This message is received when a valid heading is first received from the ship's
sensors.
Rate of Turn indicator in use (Information 33)
Other ROT source in use (Information 34)
The first of these messages indicates that the M-2 transponder is using Rate of
Turn information from an on-board device which directly calculates the rate of
turn - such as a gyro compass. The second message indicates that the rate of
turn is being calculated from changes in the ship's heading.
Chan management params changed (Information 36)
This message is issued each time that any of the channel management
parameters are altered. These may be altered by the receipt of specific VHF or
DSC messages from base stations and can also be modified directly by using
the "Channel Regions" page on the M-2's display unit.
All transmissions enabled (Information 63)
All transmissions disabled (Information 64)
These two messages indicate that all transmissions by the transponder have
been enabled or disabled as appropriate. When the transponder is first powered
up it is not allowed to transmit for a period while it listens to transmissions from
nearby vessels in order to ensure that it does not interfere with them. The
message "All transmissions disabled" is displayed as a reminder that the AIS is
not operational for this time. After approximately 90 seconds, the transponder
will begin transmissions and the message “All transmissions enabled" is
displayed.
These messages are also generated if the transmitter is inhibited while the AIS
unit is in operation.
Own reports enabled (Information 65)
Own reports disabled (information 66)
These messages are displayed when the transmission of AIS "Own Vessel"
reports are enabled or disabled as a result of moving across the boundary of
channel management region. When moving into a channel management region
52 Issue 1 M-2 AIS Operation
in which AIS transmissions are disabled, the message "Own reports disabled" is
displayed as a reminder that no AIS information is being transmitted. When the
vessel moves out of that channel region (or the transmission mode with in that
region is updated) the message "Own reports enabled" is displayed as a
reminder that normal operation has been restored.
Area setting uses invalid mode (Information 67)
This message is output by the transponder when an attempt is made to
configure a channel management region which has value for the 'mode' field
which is greater than 5 (the maximum permitted by IEC 61162-1).
Area setting uses unsupported mode (Information 67)
This message is output by the transponder when an attempt is made to
configure a channel management region which has value for the 'mode' field of
either 3 or 4, as these modes are not supported by this transponder.
Area is too small (Information 67)
Area is too large (Information 67)
One of these two messages will be output by the transponder when an attempt
is made to configure a channel management region which has at least one side
which is shorter than 20 nm longer than 200 nm.
Transition zone is too large (Information 67)
This message is output by the transponder when an attempt is made to
configure a channel management region which has a transition zone size of
more then 5 nm .
Area setting has corner conflict (Information 67)
This message is output by the transponder when an attempt is made to
configure a channel management region of which one corner lies to close to the
corners of existing regions. It is not permissable to have more than two regions
sharing a common corner, or for three or more reigons to have corners within
8nm or each other.
Area overruled by prior command (Information 67)
This message is output by the transponder when an attempt is made to
configure a channel management region which overlaps with a region which has
been set by either DSC tele-comand or by a VHF message within the last two
hours. Regions received by these means cannot be changed by manual editing
until at least two hours after they have been received.
Area setting uses invalid channels (Information 67)
This message is output by the transponder when an attempt is made to
configure a channel management region in which either (or both) of the
specified AIS channels are not valid channel num bers as defined in ITU-T
M.1084 Annex 4.
