SEN 1, 2, 3 ports - Sensors
The Sensor input port can be configured to receive data from the Gyro, the GNSS used for
navigation and the LOG. Each of the three sensor (SEN1, SEN2 and SEN3) ports can be
independently configured to receive information from one of these sensors. Alternatively ALL
sensor information can be received via ONE of the sensor ports.
The sensor ports require configuration before use; this is described in the Operation Manual.
The AIS must be connected to:
• The GNSS unit used for navigation
• The gyrocompass providing heading information
If available the following information can be connected to the AIS:
• Rate-Of-Turn (ROT)
• Speed over ground from Bottom referenced log

Main and AUX high speed input/output ports
The Transponder has two high-speed communication ports. The ports are identical, the same
information is input and output on these ports. All information received and transmitted on the
VHF link will be reflected as correct IEC 61162 sentences. All error messages will also be
transmitted.
The Main port will primarily be used to connect external equipment such as ECDIS and ARPA
or another navigation information display system.
The AUX port will primarily be used for connection to the “pilot plug” - a connector installed on
the bridge near the pilot operation position so that the pilot can connect a Personal Pilot Unit,
which is normally a laptop computer with the pilot’s navigational software installed.

LRF port, Long Range Function
The AIS Long-Range Function requires a compatible long-range communication system e.g.
Inmarsat-C. If this is available, a connection to the Inmarsat-C system can be made. It is
required that the Inmarsat-C input/output port can be interfaced using IEC 61162-2 and
understand the long-range sentences as required by IEC 61993.
Recommended cable for connection of LRF-port:
Three twisted pairs, shielded, PVC sheathed.
Cable length to display Required dimension
0 – 100 metres 0.8 mm2 each wire
LRF port wire connection
The twisted pairs shall be assigned as (RxA/RxB), (TxA/TxB) and (RxCom/TxCom)
RTCM port, Differential GNSS correction input/output port
The RTCM-port is the input/output port for differential correction. The UAIS Transponder can
receive differential correction in two ways:
• The RTCM port can be connected to a DGNSS unit. The DGNSS unit will then provide
differential correction to the AIS Transponder through the RTCM port.
• Through message 17 transmitted from a base station. The RTCM port will then work as
an output port, which can supply differential correction in RTCM format to other units.
Recommended cable for connection of RTCM-port:
Three twisted pairs, shielded, PVC sheathed.
Cable length to display Required dimension
0 – 100 metres 0.8 mm2 each wire
RTCM port wire connection
The twisted pairs shall be assigned as (RxA/RxB), (TxA/TxB) and (RxCom/TxCom)
BIIT, Built In Integrity Test relay function
The AIS requires that an alarm output (relay) be connected to an audible alarm device or to the
ships alarm system, if available.
If any failure or malfunction is detected that will significantly reduce integrity or stop operation of
the AIS, an alarm is initiated. In this case:
• An alarm message is displayed on the VDU
• The alarm BIIT relay shall is activated
• An appropriate alarm message is output via the presentation interface (Main and AUX-
ports) and repeated every 30 seconds.
The UAIS transponder provides a relay connection, which can be selected as normal closed or
normal open contacts.
Recommended cable for connection of BIIT relay:
One twisted pair, shielded, PVC sheathed. The required cable dimension is dependent on
the current necessary to activate the alarm indicator.
![](/img.php?id=390818&img=bg7.png)
89-041 Section 4 Issue 5 S4-11
Built in alarm (BIIT) relay ratings:
Absolute maximum ratings
Maximum switching current in contacts 0.25 Amp
Maximum carry current 1.20 Amp
Maximum switching voltage 175 V (d.c. or a.c. peak)
Completion of Installation
The foregoing provides the information necessary to perform the installation. Other useful
information is contained in the sections following.
The Pre-Installation Inspection Record (Section 8) should have been completed before
installation commenced.
It is most important that the installed system is not switched on at this stage. The
inspection procedures given in the Operation Manual must be completed before power is
applied.
The Warranty and Acceptance Record can only be completed after the system is configured, as
detailed in the Operation Manual.

Termination
Termination resistors are required at each end of the RS-422 connection. The effect of the
termination is to increase the input loading of that port, as seen by the talker. The figures quoted
assume that the line is correctly terminated, and allow for that extra loading.
Output drive capability
Each talker output has a capability of driving a minimum of 12 listeners on a terminated cable.
Input loading
Each receiver presents a load of approximately 12kohm to the line. Line termination resistors
are 120 ohms.
Isolation
The interface isolation is 1kV minimum throughout.

6 - Serial interface communications protocols
As previously stated, the Transponder has seven RS-422 interfaces which are all available on
the Screw Terminal board:
• 3 sensor data input ports SEN1, SEN2 and SEN3
• 2 Bi-directional input/output ports MAIN and AUX/Pilot
• 1 Bi-directional input/output port RTCM
• 1 Bi-directional input/output port LR (Long Range)
Sensor data interface
The Sensor data input ports receive navigational data in NMEA–0183 format from the
connected sensors. The connected sensors can be a GNSS unit used for navigation, a
gyrocompass and a bottom track log. These data are processed in the UAIS unit and
transmitted as dynamic data. The data received by other stations over the VHF link form an
image of the sensor data. It is therefore vital that the sensor data are correct and that the port is
correctly configured.
The sensor ports of the UAIS Transponder understand the following IEC 61162 sentences. The
priority order of listing is left to right:
Latitude & Longitude: GNS, RMC, GGA, GLL
Speed Over Ground: VBW, RMC, VTG, OSD
Course Over Ground: RMC, VBW, VTG, OSD
Heading: HDT, OSD
Rate Of Turn: ROT, calculated from heading (HDT, OSD).
Navigational data must be received via the sensor ports within certain intervals; the maximum
intervals are listed in the table below. If NMEA sentences containing identical information arrive
at the sensor input ports, the UAIS Transponder will choose the information with the highest
priority level.
The built-in GNSS unit will under normal conditions only be used for TDMA slot timing. However
if no data are received from the external sensors, the built-in GNSS unit can be set to take over
automatically and supply navigational information for the VHF data link transmission. The
changeover between internal GNSS information use and external sensor information use
happens automatically, information received from the external sensors has priority and will
always be used when available.

Route plans with positions are transmitted in RTE (Routes) and WPL (Waypoint location)
sentences. There is no update interval for these data, therefore the last updated Route plan will
be kept in memory until data are updated or the power is switched off, as the data are not kept
in the permanent memory.
The UAIS Transponder will only accept the RTE sentence if the “w” attribute is in its 4th field
(current Route plan). WPL sentences can be sent before or after the RTE sentence. The
Transponder supports memory space for 22 Route plan positions; inactive positions are
gradually removed from memory and replaced with new data.
Main and AUX port reception and transmission of UAIS data
Specific UAIS Transponder functions are available via the Main and AUX ports. The ports are
identical and will transmit all received VDL (VHF Data Link) messages as well as Transponder
error messages. A request for information may be sent from equipment connected to the Main
and AUX ports, ether a request for information or a request for the Transponder to carry out a
specific task. The communication protocol is text, but in non-readable sentences which contain
compressed binary data.
The Transponder Main/AUX input port can accept requests:
• To send a short text message or a small binary data array to a specified address
(MMSI) or as a broadcast message
• To send a static or voyage information request to a specified address (MMSI)
• To change AIS radio frequencies and/or parameters of access to AIS channels
(radiating power, frequency band etc.)
The Transponder Main/AUX input port can accept:
• Static and voyage related data
• Navigation or dynamic data, similar to sensors data interface
• Error situation message acknowledgement.
The Transponder Main/AUS output port can transmit:
• Notifications about every VHF message received and transmitted via AIS channels
with the VHF message included;
• Acknowledgement of requests from other stations;

External illumination
The VDU does not require external illumination during operation, as it has an internal backlight;
the use of on-screen keys ensures that all controls are visible in the screen backlight.
However, it is recommended that some form of illumination, possibly temporary, is provided
during installation and maintenance.

89-041 Section 3 Issue 4 S3-11
Antenna units
The UAIS Transponder has to be connected to two antennas: a VHF antenna and a GNSS
antenna.
Antenna mounting position
In accordance with IMO guidelines, antennas should be mounted in positions which, as far as
possible, minimise interaction between them. The sketch summarises the recommendations:
VHF antenna
The VHF antenna is an important part of the receiver and transmitter system; the reception
range is heavily dependent on the antenna installation. The VHF antenna must be installed as
high as possible and free of shadow effects from the ship superstructure; effective installation
will maximise the range of the system. The antenna must also be mounted so as to achieve the
safety standards detailed on Page 3 of the Preface.
WARNING: The antenna must have sufficient bandwidth to suit the UAIS system, as otherwise
the high VSWR produced may cause the transponder to shut down. It is recommended to use
an omni-directional vertical polarised VHF antenna with a gain of 3 – 5 dBi, and a bandwidth
sufficient to maintain VSWR <1.5 over the frequency range 156 – 163MHz. A suitable antenna
is available from McMurdo as an option, part number 89-020-001.
GNSS antenna
The Transponder package contains a GNSS antenna and a mounting bracket. The mounting
bracket is designed for welding to the ship’s superstructure.
Installation of the GNSS antenna is critical for the performance of the GNSS, which is used for
timing of the transmitted time slots and for the supply of navigational information should the
main navigational GNSS fail.
1. The GNSS antenna must be mounted in an elevated position and free of shadow effect
from the ship’s superstructure
2. The GNSS antenna must have a free view through 360 degrees with a vertical angle of 5
to 90 degrees above the horizon.

3. As the received GNSS signal is very sensitive to noise and interference generated by
other onboard transmitters, ensure that the GNSS antenna is placed as far away as
possible from Radar, Inmarsat and Iridium transmitters. Ensure the GNSS antenna is free
from direct view of the Radar and the Inmarsat beam
WARNING: Screw the rod into the GNSS antenna by turning the rod. Do not turn the GNSS
antenna as this will twist the cable and damage the connection.

4 - Electrical connections
This installation guide takes into account the IMO “Guidelines for installation of Shipborne
Automatic Identification System”. However both the IMO publication and these instructions must
be taken as guidance only; individual circumstances must take precedence.
This guide is concerned only with the installation of the UAIS transponder unit and does not
cover the installation of any peripheral equipment connected to the transponder. For proper
installation and connection of peripheral equipment to the transponder refer to the installation
manual for these products.

Signal cable connections for UAIS Transponder
As shown in the table above, the UAIS Transponder must be or may be connected to different
types of peripheral units; these can be divided in three groups:
• Coax connection to the antennas
• signal cable connection to the sensors (GNSS, Gyro, Log)
• signal cable connections to the five-input/output ports (Main, AUX/Pilot, long-range,
RTCM, Display)
Connecting the three types of interfaces is described in detail in the following chapters.
The signal connections are all connected via a serial RS422 type interface; baud rates are from
1200 to 38400.
In some cases, particularly in retrofit installations, it may not be possible to connect the UAIS
directly to the required sensor, because some sensors do not provide the IEC 61162-2 (NMEA)
sentences required by the UAIS unit. In such cases a protocol converter is required between the
sensor and the UAIS unit. Converters are available from different manufacturers, either as direct
![](/img.php?id=390818&img=bg20.png)
S4-2 89-041 Section 4 Issue 5
protocol converters or frequently as repeater instruments for the sensor. A Gyro Interface Unit,
P/N 89-028, is available from McMurdo as an optional extra.
VHF and GNSS (GPS) antenna cable connections
The VHF and the GNSS antenna cables are connected directly to the transponder through a
UHF and a TNC plug respectively.
The coax cable plugs must be attached directly to the cables; the outer insulation must not be
connected in the cable cleat but in the coax plug as illustrated below.
VHF antenna
The VHF antenna is an important part of the receiver and transmitter system; the reception
range is heavily dependent on the antenna installation. It is recommended to use an omni-
directional vertical polarised VHF antenna with a gain of 3 – 5 dB. The VHF antenna must be
installed as high as possible and free of shadow effects from the ship superstructure; effective
installation will maximise the range of the system.
In accordance with the IMO guidelines, an exclusion zone is defined around a VHF antenna;
other antennas must be mounted outside this zone.
To make sure that the transmitted and received VHF signal is not interfering with Radar signals,
other VHF transmission or power lines it is important that the connection between the VHF
antenna and the transponder is of a high quality double shielded coax cable. It is recommended
to use a RG214 cable and PL259 or N-type connectors.
If the cable has to be longer than 40 metres, it is recommended to use a cable with lower loss; a
40 metre RG214 coax cable has a signal attenuation of 3 dB at 150MHz, thus the signal
strength is reduced to half its value due to cable attenuation.
![](/img.php?id=390818&img=bg21.png)
89-041 Section 4 Issue 5 S4-3
GNSS (GPS) antenna
The GNSS (GPS) antenna has to have a clear view of the sky, the objective is to see the
horizon freely through 360 degrees with a vertical view of 5 to 90 degrees above the horizon.
As the received GNSS signal is very sensitive to noise and interference generated by other
onboard transmitters ensure that the GNSS antenna is placed as far away as possible from
Radar, Inmarsat and Iridium transmitters. Ensure the GNSS antenna is free from direct view of
the Radar and the Inmarsat beam.
It is also important that the MF/HF and other VHF transmitter antennas are kept as far away as
possible from the GNSS antenna. It is good practice never to install a GNSS antenna within a
radius of 5 meters from these antennas.
The GNSS operates in the ultra high frequency band (1.575 GHz). The signal attenuation in
cables is therefore substantial and has to be taken into account when the coax cable between
the antenna and the UAIS unit is chosen. To compensate for this signal attenuation the supplied
GPS antenna includes a pre-amplifier with a gain of 36 dB.
The optimum combination of coax cable and GPS antenna gain will have a resulting installation
gain (pre-amplifier–cable attenuation) within 0 to 10 dB. The table below shows examples of
coax cables.
Cable description Attenuation / 100metre Maximum cable length
RG 58 70 dB @ 1.5GHz 40 metres
RG214 37 dB 90 metres
Connectors used must be TNC throughout.

S4-4 89-041 Section 4 Issue 5
Screw terminal board
The UAIS Transponder has a build in screw terminal board which makes it very easy during
installation to connect cables to the power sources, to sensors, to the VDU and to other display
units through the Main and AUX ports.
Refer to the wiring diagram, attached as an appendix, for details of connections to the screw
terminal board.
Fuse values
The main system fuse (10 amp) is located on the screw terminal board. A separate fuse (1 amp)
on the screw terminal board protects the VDU. Both power supplies are reverse polarity
protected.
Fuse description Fuse value Part No.
Main system fuse 10.0 Amp 99-077
VDU system fuse 1.0 Amp 99-076
Signal line termination
Signal lines may need termination by a resistor across the inputs. These resistors are
incorporated on the screw terminal board and can be switched in or out by the switches S2, S4,
S5, S6, S7, S8. The switches are identified on the Screw Terminal Board diagram on Page 6.
Note:
1. Each switch is a double unit
2. S2 and S5 each control two signals individually
3. S4, S6, S7 and S8 – both switches should be moved together
4. S3 has been deleted
![](/img.php?id=390818&img=bg23.png)
89-041 Section 4 Issue 5 S4-5
Whether termination at the terminal board is required depends on how the other units are
connected, and whether any of these other units provides termination for the signal line. The
following sketch shows the principle:
There is only one talker per twisted pair; there can be several listeners. The requirement is that
terminations must be provided by the devices at the ends of the line, regardless of whether they
are listeners or the talker, and that no other device should provide a termination.
A terminal is provided for the common connection at each port on the screw terminal board;
particular care should be taken to ensure that the cable screen is connected to ground only at
the talker.
Do not connect the cable shield to ship’s ground at both ends of the cable as this may cause
ground loops and interference to the signals.
Note: For clarity, the sketch shows the devices connected to the twisted pair by spurs; in
practice, the twisted pair is looped through each device in turn.
It is good practice to use screened cables in all ship cable installations. In the transponder unit
the screen from some cable entries should be connected to ground at the entry to the
transponder unit, as shown in the table. The technique of connecting the screen is illustrated
below.

Installing the UAIS Transponder System Safely
Installation
WARNING: Do not connect the UAIS transponder system to a mains (line) AC electrical
supply, as an electric shock or fire hazard could result.
CAUTION: Do not connect the Transponder to a DC supply exceeding 32V or reverse the
supply polarity. Damage to the transceiver can result.
CAUTION: Do not bypass the built in fuses
CAUTION: The Transponder system is designed for operation in the temperature range
-15°C to +55°C. Do not install (or use) the transponder system in environments which exceed
this range.
CAUTION: The UAIS Transponder is not water-resistant. Consequently, the Transponder
must be installed in a dry place and must be protected from direct contact with water.
WARNING: Do not install the Transponder system in a position where;
a) the controls of your vessel may be obstructed.
b) it may obstruct your normal movement around your vessel.
c) it may cause bodily injury.
d) it cannot be easily accessed in an emergency.
Use
WARNING: Certain parts of the Transponder chassis can become hot during extended
periods of operation, notably the rear panel. Avoid touching these areas when the Transponder
is operating.
WARNING: Do not dismount the cover of the Transponder before the power is switched off.
Do not touch the antenna connections when the Transponder is operating and do not touch the
antenna whip (mast) or connecting cable when the Transponder is in operation, for RF
exposure and electrical safety reasons. Refer to Radio Frequency Exposure Warning.
WARNING: Unauthorised opening of the Transponder system will invalidate the warranty.
Maintenance
CAUTION: Avoid using chemical solvents to clean the Transponder system as some
solvents can damage the case material.
NOTE: Apart from the fuses located on the Screw Terminal Board, the Transponder system
contains no user serviceable parts. Return to your Service Agent for repair if replacing the fuses
fails to make the equipment servicable.

89-041 Preface Issue 5 P7
Radio Frequency Exposure Warning
To meet the current requirements for Radio Frequency Exposure it is necessary to install the
antenna mast correctly and operate the equipment according to the instructions.
The assumptions used in this assessment are: full transmit power is used, a good antenna is
used (assumed to be a 6dBi-gain omni-directional type).
Where no suitable structure exists to achieve a 3 metre vertical separation then the antenna
base must be mounted at least 1 metre above the head of any person within range and all
persons must stay outside the 3-metre safety radius.
Failure to adhere to these limits could expose persons within the 3 metre radius to RF radiation
in excess of the MPE / SAR limits.
WARNING: The antenna mast must be mounted at a
minimum distance (vertical separation) of 3 metres from the
head of any person standing on deck to meet international safety
directives on Maximum Permissible Exposure (MPE) / Specific
Absorption Rate (SAR).
WARNING: Do not transmit when persons are closer than 3
metres to 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.
Rules of Operation
Licensing
IMPORTANT: In most countries the operation of the UAIS
Transponder is a part of the radio regulations and therefore the
ship must possess a current VHF radio telephone licence which
lists the UAIS system, and the equipment must be registered
(Call Sign and MMSI number). Please contact the relevant
authority in your country for more information.
Refer to the UAIS Transponder Operation Manual for the full operating procedure.
Good Practice
The installer is expected to be familiar with IMO SN/Circ.227 Guidelines for the Installation of a
Shipborne Automatic Identification System, and to comply with these recommendations. The
document contains detailed information which supplements the instructions in this manual.
89-041 Section 1 Issue 4 S1- 1
1 - Introduction
It is recommended that the vessel should be surveyed prior to commencing any installation
work to determine the suitability of the existing on-board sensors. Section 8 of this Manual
contains a ‘Pre-Installation Inspection’ form to assist this process.
Installation of the UAIS Transponder has been designed to be as easy as possible and requires
few tools. However as the UAIS equipment forms a vital part of the ship’s navigational
equipment the installation must be performed with great care and with attention to detail.
The UAIS is considered part of the ship’s radio station and is surveyed together with the radio
installation. Surveys on Convention ships should be carried out in accordance with the rules laid
down in IMO Res. A 746(18) Survey Guidelines under the harmonised system of survey and
certification and Protocol of 1988 relating to the International Convention for the Safety of Life at
Sea 1974
For the AIS installation the following drawings shall be submitted for the survey:
• Antenna layout for the VHF and the GNSS antenna installation (prepared by the installer)
• AIS Arrangement drawing (included in this manual)
• Block diagram showing the interconnection to other units (included in this manual)
It is also necessary to complete an installation report, which shall be kept on board.
About this manual
This manual provides step-by-step guidance through the installation of the UAIS Transponder
system. Please read the manual carefully and make sure to follow the instructions.
In this manual only the installation of the UAIS stand-alone configuration will be described. If the
UAIS unit is to be connected to other display devices, refer to the manual for that display.
However the setup must always be performed with the display unit. Other display units will be
additional to the IMO required installation.
The procedures required for installation can be summarised:
1. Obtain a copy of the UAIS Pre-installation Inspection form; check that it is filled in with all the
data necessary for the installation. If the form has not been filled in, it is advisable to do it at
this stage, as this is a good way to make sure that all information is available for the
installation.
2. The available UAIS Transponder system building blocks are listed in section 1.2. Before
starting the installation ensure that everything needed for the installation is to hand.
3. Locate the places to install the different units. The templates and the drilling instructions are
provided in this manual.
4. Connect the units and the sensors as shown in this manual.
5. DO NOT SWITCH ON THE SYSTEM AT THIS STAGE. It is most important to read the
Operation Manual, which contains the commissioning information, before power is applied.
The Warranty Registration & Acceptance Record, Section 7 at the rear of this manual, must be
completed and signed when the system has been commissioned and accepted.

2 - UAIS Transponder System
System overview
Universal Automatic Identification System (UAIS) is a maritime VHF-based transponder system
that provides high-speed automated communication from ship-to-ship and ship-to-shore, of
vessel, voyage and safety related data. This UAIS transponder and touch screen VDU display
system is the latest in state-of-the-art technology and is designed to meet the latest IMO
SOLAS requirements.
The UAIS transponder transmits the ship’s navigational data to other vessels, and also to shore
based VTS systems utilising various marine VHF channels. UAIS is primarily designed as a
ship-borne mobile station and consists of an integral GNSS engine used for timing, one VHF
transmitter, three VHF receivers and a computer unit. Interfacing to external GNSS used for
navigation, a VHF antenna, a gyrocompass, and an optional ECDIS or ARPA display system is
made easy by the built-in screw terminal board and the intuitive operating menu system on the
touch-screen display unit.
The VDU is designed to fulfil the minimum SOLAS requirements for system set-up and display
of the received target information (Minimum Keyboard and Display – MKD). However the large
touch screen LCD display also gives the user easy access to the menu system that controls the
system, and displays the received targets on a graphical, radar-like display.
Note: SOLAS requirements specify this equipment as Minimum Keyboard and Display (MKD).
Because all keyboard functions are implemented through the touch screen, it is more logical to
use the term VDU (Visual Display Unit); this terminology is used throughout this manual.
Compliance
This UAIS is designed to comply with current international standards and is approved in
accordance with the high standards of the European Marine Equipment Directive.
Compliances:
• MSC.74(69)
• ITU-R M.1371-1 1998
• EN 60945 4th edition, 2002; IEC 61993-2, 1st edition, 2001; IEC 61162-1, 2nd edition,
2000; IEC 61162-2, 1st edition 1998; IEC 61108
• ETS 300 113

S2-2 89-041 Section 2 Issue 5
System Configuration
The UAIS system can be installed either as part of an existing bridge installation, or as an
integrated part of a new bridge layout.
The main three configurations are:
1 a stand-alone system
2 a system connected to an ECS
3 a system integrated into the bridge ARPA and ECDIS displays.
The stand-alone installation as illustrated below meets the SOLAS requirement for an AIS
installation. This installation uses the minimum display (VDU) as the main display for setting up
of own ship’s information and for display of the received navigational information.
The VDU provides the received navigational information in a graphical mode making it very
easy to achieve a situation overview.
![](/img.php?id=390818&img=bg33.png)
89-041 Section 2 Issue 5 S2-3
In the Electronic Chart System (ECS) installation the stand-alone installation and an ECS
display have been integrated. This installation meets the SOLAS requirements for an AIS
installation. The VDU will mainly be used for input of own ship’s information and a compatible
ECS capable of decoding the NMEA standard implemented for UAIS will display the received
navigational information as AIS targets. This of course will greatly enhance the use of the
received target information, as the targets now will be displayed in the environment used for
navigation of the ship.
![](/img.php?id=390818&img=bg34.png)
S2-4 89-041 Section 2 Issue 5
Integrating the AIS into an integrated bridge system (IBS) will display the received AIS target
information on a compatible ARPA or ECDIS giving the navigator the optimum use of the
received navigational information. The target information is then displayed in a way that makes
it easy for the navigator to see course, speed, rate and direction of turn of other approaching
vessels.
If the ARPA or ECDIS equipment is approved for use together with the AIS transponder the
VDU may not be required in the installation. However in many cases it will be necessary to
install the VDU to meet the SOLAS requirements. In these installations the VDU will be used to
load the transponder with own ship data and the ARPA or ECDIS equipment will be used to
display the received target information.

89-041 Section 2 Issue 5 S2-5
Transponder
The Transponder consists of a backplate to which a Screw Terminal Board, the Transponder
module and the cover are attached. The Transponder is connected to the Screw Terminal
Board via ribbon cables, making the Transponder easily to disconnect without the need to
disturb the interface cables. This feature makes it very easy to interchange Transponders,
keeping repair time to a minimum.
Installation of the Transponder is made as easy as possible, as interface cables can be
connected directly to the built in Screw Terminal Board. The keyholes in the back plate make it
simple to attach the Transponder to a bulkhead.

S2-6 89-041 Section 2 Issue 5
Display
The display unit (VDU) can be tabletop or bulkhead mounted. The necessary brackets for
mounting are included and are very easy to use. A single cable connects the VDU to the
Transponder unit.
Note: SOLAS requirements specify this equipment as Minimum Keyboard and Display (MKD).
Because all keyboard functions are implemented through the touch screen, it is more logical to
use the term VDU (Visual Display Unit); this terminology is used throughout this manual.

3 - Mechanical Mounting options and guidelines
Location
The Transponder unit may be mounted in any convenient location. However, it is classed as
protected equipment and thus should be located inside in a dry environment. Normally the
transponder is located in the Radio Room. The transponder compass safe distance is 2.3m.
The VDU (MKD) should be available to the mariner at the position from which the ship is
normally operated. The VDU compass safe distance is 0.6m.
The Pilot Plug should be installed on the bridge near the pilot’s operating position.
Special considerations apply to antennas. These are outlined in the appropriate section; for
detailed advice, see the IMO Guidelines.
UAIS Transponder unit
The Transponder is attached to the bulkhead by four M6 screws. Keyhole slots in the
Transponder allow the screws to be inserted in the bulkhead, then the Transponder to be
mounted on the screws and to be self-supporting while the screws are tightened.
It is recommended to leave at least 300 mm free space below the Transponder to allow for
connection cables, as shown below right.
Transponder main dimensions
Note: When open, the transponder
chassis projects 350mm from the
mounting surface
