1 SAFETY INSTRUCTIONS
General
Saab AB (publ), TransponderTech assumes no liability for customer not complying with requirements in this section or warnings and cautions elsewhere in this document.
This safety instruction section refers to all components of the R6 SUPREME System, referred to as “equipment” in this section.
Installation and Service
Only qualified technicians shall do installation and servicing of equipment. Electrical fuses must be replaced with correct types.
To prevent electrical chock hazard and damage to the equipment, the equipment shall be connected to electrical ground. A power supply corresponding to the voltage rating of the equipment shall be used. Failure to comply with this requirement may damage the equipment.
To ensure proper functioning of the equipment, only signal cables and antennas specified in this document may be used. Failure to comply with this requirement may cause unexpected behavior of the equipment.
The equipment may not in any way be modified; doing so may cause fire, shock hazard or serious injury.
AIS Operational safety considerations
AIS Systems are very powerful tools, assisting safe navigation, which many vessels are equipped with. AIS enables vessel identification and positioning, enhancing navigational safety.
However, it is important to know that:
Smaller vessels are more likely to not be equipped with AIS at all.  There are different classes of AIS equipment. Some non-SOLAS vessels may carry Class B
AIS equipment with 30s or more between position reports.
AIS information is only as good as the input it gets. Should any input to the AIS malfunction and
provide incorrect data (such as Heading, ROT, COG, SOG, Position), this data may still be reported to nearby vessels. The mariner should therefore be aware that received AIS data could
be incorrect. Each Voyage requires updating of Voyage related AIS settings Considering this, it is important to use multiple sources of information for decision-making. To ensure proper operation of the AIS system, make sure to view the Alert List for any
irregularities in system operation and verify any voyage settings are correct. Further, in many cases there is a carriage requirement that a Class A - AIS system must be installed
and fully operating on the vessel. Some administrations may allow the AIS to be switched off when continual operation of AIS compromise the safety or security of the vessel or where a security incident is imminent. Turning off the AIS will result in a Non-Functioning Time Log entry.

2 THE AUTOMATIC IDENTIFICATION SYSTEM
The Automatic Identification System (AIS) is a safety information system that was proposed as a worldwide standard in 1997 and adopted by IMO in 1998. The AIS system is standardized by ITU, IEC, IALA and IMO and is subject to approval by a certification body. The first type approved AIS transponder in the world was Saab TransponderTech’s R3 Class A Transponder in 2002.
AIS allows transceivers to automatically share static and dynamic data such as ship name, call sign, dimensions, position and sensor information on two dedicated data links in the upper marine VHF band. There are a number of different AIS devices that can send and receive information on the AIS data link:
Class A Transponder – This type of transponder is used on open sea waters and is
mandatory for ships of 300 gross tonnage or more on international voyages, all cargo ships of 500 gross tonnage or more and on passenger ships.
Class B Transponder – Used on smaller vessels and pleasure crafts. It transmits with a lower
power than the Class A transponder and has lower priority on the data link. Two sub categories exist: Class B CS with 2W output and 30s report interval, and Class B SO with 5W output and up to 5s report interval.
Base Station – Fixed shore station that is typically connected to an AIS network to collect
information from all vessels at a certain port or shore line, and may also transmit information such as text messages, weather data and virtual ATON markers.
Repeater Stations – Used to extend coverage range by repeating incoming messages. Can
also be implemented as a function in an AIS Base station or an AtoN station.
SAR (Search and Rescue) Transponder – Used on airplanes and helicopters in search and
rescue missions.
AtoN (Aids to Navigation) – A transceiver that is fitted on buoys and lighthouses in order to
send information about their positions.
MAtoN (Mobile Aids to Navigation) – A nonfixed or unmoored AtoN; but does not include
a fixed or moored buoy that is adrift from station, temporary or otherwise
Inland AIS – A European standardized extension to Class A systems for use on inland water
ways. An inland transponder has additional messages to communicate with bridges, ports and locks and can also send some additional information that are useful on water ways such as blue sign indication, specific hazardous cargo etc.
Locating Devices – Emergency and distress location transmitters e.g. AIS-SART, EPIRB-AIS
and MOB-AIS.

3 SYSTEM OVERVIEW
Product Description
The basic R6 SUPREME System consists of two central parts
The R6 SUPREME Transponder
The R6 CDU (Control and Display Unit)
The R6 SUPREME Transponder is a system that consists of a VHF Data transceiver, a 48 channel GNSS receiver, and a controlling unit. In Class A - AIS operation, the system enables at least two AIS receiver processes and one DSC receiver process. The transmitter alternates its AIS transmissions between the two AIS channels. The controlling unit creates and schedules data packets (containing dynamic, static and voyage related data) for transmission based on the IMO performance standard for AIS, and manages any data processing necessary.
The R6 SUPREME system shall be connected to the ship’s sensors as required by the installation
guidelines published by IALA and IMO. The R6 SUPREME can interface external navigation and presentation systems that support required sentences using IEC 61162-1/2, as well as IEC 61162­450 interfaces. Refer to Section 11 for more information. The R6 SUPREME is prepared for connection to Long Range systems like Inmarsat C.
To facilitate connection to serial devices, as well as provide power fuses, installation of the R6 Junction Box is recommended.
The R6 CDU is a graphical display with touch and keypad input, type tested to meet AIS MKD (Minimum Keyboard and Display) requirements, and is used to control and monitor the AIS system. The colour LCD together with the touch interface provides a graphical user-friendly interface to the system. The rubber keypads may be used for many basic operations instead of the capacitive touch interface, in cases such as under rough sea or with gloved hands. With the R6 CDU it is possible to plot the location of other ships, aids to navigation and search and rescue vessels. The R6 CDU can also be used to send and receive messages, perform configuration as well as supervise the R6 SUPREME transponder status. The front of the R6 CDU is designed to allow for a water proof panel mount installation, and the rear of the CDU has an SD card slot for service and Firmware updates.

Installing the R6 CDU
4.6.1 CDU Location
The R6 CDU should be mounted close to the position from which the ship is normally operated, preferably on the bridge console close to the conning position.
When mounting the R6 CDU, please consider the following:
The temperature and humidity should be moderate and stable, operating temperature: -
15ºC to +55ºC.
Select a location away from excessive heat sources  Avoid areas where there is a high flow of humid salt air  Avoid places with high levels of vibrations and shocks  Avoid mounting the R6 CDU in direct sunlight. Prolonged exposure to direct sunlight may
have adverse effects to the system.
Ensure that there is enough airflow to avoid high ambient temperatures  The units can affect magnetic compasses.
o The minimum compass safe distance from the R6 CDU is 0.65 meters to a
standard magnetic compass and 0.40 meters to a steering magnetic compass.
4.6.2 R6 CDU Mounting Options
The R6 CDU can be mounted in three different ways.
Panel mount – Using the R6 CDU Flush Mount Kit (7000 123-142) Gimbal mount – Using the R6 CDU Gimbal Mount Kit(7000 123-140)  Frame mount – Using the R6 CDU Mounting Frame(7000 123-119)
4.6.2.1 CDU Gimbal Mount
The gimbal mount allows for a quick installation, and is suitable for panel as well as ceiling mounting. It will give the benefit of a tilt-able display for optimal viewing angle.
The gimbal mount is fastened with four screws in the mounting surface. The CDU is attached to the gimbal mount with two wing knobs.
Make sure any connected cables that could transport water are installed in a way that will allow for drip off before reaching the R6 CDU. The connectors are not water protected and shall not be the lowest point for external cables if there is a risk of water transport along the cable.
The CDU Gimbal mount is offered as an accessory to the R6 CDU, and may be optional in some sale packages.
4.6.2.2 Panel Mount
Panel mounting will reduce bridge clutter and reduce the space needed for installation. A cut­out fitting the CDU profile must be made. See Section 17.4 CDU Cut-out Measurements for Panel Mount for dimensions.
Panel mounting with proper sealing between the R6 CDU and the panel, will enable a splash proof installation of the R6 CDU. Note, only the front of the R6 CDU is protected from water
R6 SUPREME System
7000 121-304, A1 Page 18
ingress, water leakage to the rear of the R6 CDU may result in water ingress through the external interfaces.
The CDU is fastened in place using the bracket and the threaded bar included in the flush mount kit 7000 123-142.
Figure 4-2 – R6 CDU Flush Mount Kit.

7000 121-304, A1 Page 19
4.7.2 R6 SUPREME Transponder Mounting
The Transponder unit is secured in place using the screw holes in the four feet in the bottom corners. When wall mounting, ensure the interface ports are facing downwards, to prevent intrusion of water that may come from connected cables.
Figure 4-3 – Transponder mounting holes locations.
R6 SUPREME System
7000 121-304, A1 Page 20
Install the R6 Junction Box
4.8.1 Junction Box Location
The Signal Cables connecting the transponder to the Junction box are 2m long and will determine the maximum distance between the Junction Box and the Transponder unit.
Leave a clearance area at the cable side of the R6 Junction Box to observe minimum cable radius recommendation. Also leave enough surrounding space to facilitate service and installation.
See below figure for minimum recommended cable clearance area.
Figure 4-4 – Recommended Clearance Area (mm) for R6 Junction Box
Observe clearance area for cables. Allow minimum 150mm for Saab DSUB Signal cables.
R6 SUPREME System
7000 121-304, A1 Page 21
4.8.1 Junction box mounting
The unit may be wall mounter or shelf mounted. When wall mounting, it is recommended to mount the unit with the cable opening downwards. This reduces the risk of water ingress.
Figure 4-5 –R6 Junction Box mounting dimensions
Open the lid of the R6 Junction Box.  Fix the box on an appropriate surface/place with using the screw holes on the four feet of
the junction box.
Shielded cables should be stripped down to the shielding and fastened with cable ties (not
included)
Connect the cables to the terminal blocks.  Fix the lid to the box casing.
NOTE: Cables meant for connection to the screw terminals inside the R6 Junction box have a maximum diameter of 13mm, due to space limitations entering the box.
4.8.2 Junction Box Interfaces
The Junction box features one 26-pin DSUB connector and one 9-pin DSUB connector. All other connectors are internal of terminal block type.
R6 SUPREME System
7000 121-304, A1 Page 22
NOTE: The R6 Junction Box has three internal fuses. F3 “AIS” fuse protects the AIS PWR output (10A), F2 “CDU” is for the CDU PWR output (2A) and F1 “JB” is for the junction box integrated
alarm relay (2A).
Figure 4-6 –R6 Junction Box interface
Please see Section 16.3 R6 Junction box Interfaces for details.
Mount the VHF Antenna
The R6 SUPREME Transponder, like any other transceiver operating in the VHF maritime band, may cause interference to a ship’s VHF radiotelephone. Because AIS is a communication system with time slotted transmission, this interference may occur as a periodic (e.g. every 10 second) soft
clicking sound on a ship’s radiotelephone. This effect may become more noticeable when the VHF
radiotelephone antenna is located close to the AIS VHF antenna and when the radiotelephone is operating on channels near the AIS operating channels (e.g. channels 27, 28 and 86).
Attention should be paid to the location and installation of different antennas in order to obtain the best possible efficiency. Special attention should be paid to the installation of mandatory antennas like the AIS antennas.
Therefore, installing the AIS VHF antenna is also a crucial part of the system installation. How and where you install your AIS VHF antenna and cable will affect its efficiency.
4.9.1 VHF Antenna Location
Location of the mandatory AIS VHF antenna should be carefully considered. Digital communication is more sensitive than analogue/voice communication to interference created by reflections in obstructions like masts and booms. It may be necessary to relocate the VHF

radiotelephone antenna to minimize the interference effects. Installing the VHF antenna for AIS on a vessel is a compromise between the following items:
Antenna type  Antenna separation  Clear view of the horizon  Antenna height
4.9.1.1 Antenna Type
The AIS VHF antenna should have Omni directional vertical polarization providing unity gain.
4.9.1.2 Antenna Separation
AIS transponders use simplex channels at frequencies on the high side of the marine mobile band (AIS channel A = 2087, 161.975 MHz, and AIS channel B = 2088, 162.025 MHz). These channels are close to the duplex channels used for shore to ship marine communication. The AIS VHF antenna should be separated as much as possible from the voice VHF installations used for main communication to avoid unnecessary interference.
There should not be more than one antenna on the same level. The AIS VHF antenna should
be mounted directly above or below the ship’s primary VHF radiotelephone antenna, with no
horizontal separation and with a minimum of 2 meters vertical separation. If it is located on the same level as other antennas, the distance apart should be at least 10 meters.
The AIS VHF antenna should be installed safely away from interfering high-power radiating sources like radar and other transmitting radio antennas, preferably at least 3 meters away from and out of the transmitting beam.
4.9.1.3 Clear View of the Horizon
The AIS VHF antenna should be placed in an elevated position that is as free as possible with a minimum distance of 2 meters in horizontal direction from constructions made of conductive materials. The antenna should not be installed close to any large vertical obstruction. The objective for the AIS VHF antenna is to see the horizon freely through 360 degrees.
4.9.1.4 VHF Antenna Height
The AIS is using VHF radio frequencies, which propagation characteristics are close to line of sight. The higher the antenna location is, the longer the range will be.
4.9.2 VHF Cabling
The cable should be kept as short as possible to minimize attenuation of the signal. Double shielded coaxial cable equal or better than RG214 is recommended to minimize the effects from electromagnetic interference from high power lines, radar or other radio transmitter cables.
The table below gives recommendation on cables that can be used for the VHF-antenna connections. The cable attenuation shall be kept as low as possible; a 3 dB loss is the same as cutting the signal strength in half.
R6 SUPREME System
7000 121-304, A1 Page 24
Example: A cable of 40 meter RG 214 has a cable attenuation of 2.8 dB.
4.9.3 VHF Cable Mounting
Coaxial cables should be installed in separate signal cable channels/tubes and at least 10 cm away from power supply cables. Crossing of cables should be done at right angles (90°).
Coaxial cables should not be exposed to sharp bends, which may lead to a change of the characteristic impedance of the cable. The minimum bending radius should be 5 times the cable's diameter.
All outdoor installed connectors should be weather proofed, e.g. with shrink tubing, watertight seal tape or butyl rubber tape and plastic tape sealing, to protect against water penetration into the antenna cable.
Secure the cable properly close to the cable ends.
4.9.4 VHF Cable Grounding
Coaxial down-leads must be grounded. The coaxial shielding screen should be connected to ground.
Mount the GNSS Antenna
The R6 SUPREME shall be connected to one of the approved GNSS antenna types. 5V DC is supplied through the antenna lead for the antenna preamplifier.
If a combined GNSS/VHF antenna is used, the diplexer unit shall be installed in an indoors environment.
Attention should be paid to the location and installation of the different antennas on the ship in order to obtain the best possible efficiency. Special attention should be paid to the installation of mandatory antennas like the AIS units antennas.
Therefore, installation of the GNSS antenna is a crucial part of the system installation. How and where you install your GNSS antenna and cable will greatly affect its sensing efficiency.
4.10.1 GNSS Antenna Location
The GNSS antenna must be installed where it has a clear view of the sky. 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 should not eclipse more than a few degrees of any given

bearing. Do not mount the antenna in the top of a mast or tower, as this may degrade the COG and SOG readings.
Locate the GNSS antenna at least 3 meters away from and out of the transmitting beam of high­power transmitters such as S-Band Radar (typically 15° vertically from the array’s centre point) and/or Inmarsat systems (A, B, C, or M; typically 10º from the array’s centre point in any of the possible transmitting directions).
Locate the GNSS antenna at least 3 meters away from HF or VHF radios or their antennas. This includes the ship’s own AIS VHF antenna if it is designed and installed separately.
4.10.2 GNSS Cabling
The gain of the GNSS antenna built-in pre-amplifier shall match the cable attenuation. The resulting installation gain (pre-amplifier gain minus cable attenuation) shall be within 0 to 26 dB. A minimum value of 10 dB is recommended for optimum performance.
Double shielded coaxial cable is recommended. The coaxial cable should be routed directly between the GNSS antenna and the R6 SUPREME Transponder’s GNSS connector in order to reduce electromagnetic interference effects. The cable should not be installed close to high­power lines, such as radar or radio-transmitter lines or the AIS VHF antenna cable. A separation of 1 meter or more is recommended to avoid interference due to RF-coupling. Crossing of antenna cables should be done at 90 degrees to minimise magnetic field coupling.
The table below gives recommendation on cables that can be used for the Transponder GNSS­antenna connections. Due to the high frequency it’s important that the attenuation in the cable is low for the specific frequency (1.5 GHz).

Electrical Installation details
For complete specification of signal interface details see Section 16 Electrical Interfaces.
4.11.1 Input ports
The protocol of the serial port interfaces is compliant to IEC 61162-1 Ed.5.
R6 SUPREME System
7000 121-304, A1 Page 27
All serial ports in the R6 SUPREME Transponder have the same capabilities with one exception, any Long Range equipment must be connected to the Long Range port. Apart from that, all ports can be connected to any external equipment such as ECDIS and external sensors. The primary external position sensor should be connected to the Sensor 1 port since this port has the highest priority. The serial ports in the R6 SUPREME Transponder can also receive differential corrections in RTCM format for the internal GNSS receiver. The ports in the R6 SUPREME Transponder have different default baud rates but they can all be configured to any baud rate of 4800, 9600, 38400, 57600 or 115200 bps. The priority levels for input of sensor data on the different ports are listed below:

4.11.8 External Switch
It is possible to connect an external switch to the R6 SUPREME Transponder. The switch may be used to quickly turn off transmissions (TX OFF), or it may also be used to
force the radio transmit power to 1W only.
NOTE: Manually set 1W mode operation, or Silent Mode, is outside of type approved operational mode.
The status of the switch can be controlled by connecting to the R6 Junction Box (R) and (F) signals in the “TX Switch terminal block.
Connect the external switch as in the figure below. When the switch is open, all VHF transmissions will be disabled or only transmit in low power mode depending on configuration. When the switch is closed, the R6 SUPREME Transponder will transmit normally or transmit at normal power level.
Figure 4-8 – External Switch
4.11.9 Alarm Relay
It is required that the AIS alert output (relay) is connected to an audible alert device or the ship’s alert system, if available. The R6 AIS Junction Box has a built in alert relay that can be connected to the ship’s alert system. If the installation is done without the junction box, an external alarm relay should be connected.
Alternatively, the ship’s alert system may use the alert messages output on the AIS Presentation Interface (PI) provided the alert system is AIS compatible. The AIS Alarm Relay is either mounted on a DIN mounting rail or direct on the wall.
The alarm relay wires have the following colour codes in the 26-pole signal cable:
