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.
Course over ground (COG) 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.
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 0 – 100 metres Required dimension 0.

Technical Information RS-422 interfaces 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) All communication interfaces are compatible with IEC-61993-2 standards.
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.

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.

2. 3. Refer to previous page for illustration of fitted clamping screw 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.
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.
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.
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.
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.
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.
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.

When updates are posted, any incompatibility with earlier issues of hardware and/or software will be highlighted here.
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.
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).
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.

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.
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.
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.
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.
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.
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.
