Marine SystemsAviation RecordersRev. 02 Page iiiJuly 29/03Automatic Identification SystemGENERALThis product and related documentation must be reviewed for familiarization with safetymarkings and instructions before operation.This board was constructed in an ESD (electro–static discharge) protected environment. This isbecause most of the semiconductor devices used in this board are susceptible to damage by staticdischarge.Depending on the magnitude of the charge, device substrates can be punctured or destroyed bycontact or mere proximity of a static charge. The results can cause degradation of device perfor-mance, early failure, or immediate destruction.These charges are generated in numerous ways such as simple contact, separation of materials,and normal motions of persons working with static sensitive devices.When handling or servicing equipment containing static sensitive devices, adequate precautionsmust be taken to prevent device damage or destruction.Only those who are thoroughly familiar with industry accepted techniques for handling static sen-sitive devices should attempt to service circuitry with these devices.In all instances, measures must be taken to prevent static charge build–up on work surfaces andpersons handling the devices.

Marine SystemsAviation RecordersRev. 02 Page 1--3July 29/03Automatic Identification SystemProTec AIS Introduction1.1. GeneralThe L--3 ProTec is an Automatic Identification System transponder which is fullycompliant to the technical specifications defined by the IMO and outlined in ITU.R.M1371--1. The transponder employs the latest radio frequency and SOTDMA andDSC controller technology to provide a high performance, automated, and reliableidentification system for commercial mariners. The Transponder is a fully automatedsystem which ties into ship’s navigational instruments to provide automatic transmis-sion of ships identity, status, and maneuvering intentions via standard marine VHFcommunication techniques. Sequencing of transmission between all vessels withinVHF range is provided through SOTDMA controlling software to handle high trafficvolume situations.The Transponder is a fully automated system. This means that once it is installedand turned on, no maintenance is required to keep it operational. The only time theuser needs to perform any function on the transponder is to change the ship’s Ves-sel/Voyage data as required.1.1.1. System OverviewThe L--3 ProTec is an Automatic Identification System fully compliant with the IMOspecifications defined in IMO MSC.74(69) Annex 3, IEC 61993--2, and ITU.RM.1371--1. This AIS transponder has been developed using technology applied inthe design of our VHF DSC Class A radio, a design which has been field tested forover a decade with over 10000 units operational in the field. With the addition of theSOTDMA controllers, the L--3 ProTec provides a cost--effective AIS solution whichwill meet the needs of any vessel required to carry AIS. The compact, single--boxdesign allows the L--3 ProTec to be easily incorporated into any bridge layout thussimplifying installation and cabling requirements.The L--3 ProTec has been designed as maintenance-free unit which makes exten-sive use of surface mount technology (SMT). The repair of printed wiring assemblies(PWAs) containing SMT components requires specialized factory equipment, train-ing, and techniques, therefore, such PWAs are not field-repairable.As a result, maintenance philosophy for the L--3 ProTec is replacement of failed as-semblies. In the case of the L--3 ProTec, the replaceable assemblies are the RFMain PWA (205M0023--00), the Channel 70 PWA (205M0003--01), the ComputerPWA (p/n: 205M0272--00), the Display PWA (205M0051--00), the IEC PWA(205M0274--00), and the Controller PWA (205M0008--00).
Marine SystemsAviation RecordersRev. 02 Page 1--4July 29/03Automatic Identification SystemWhen it has been determined that one or more of these assemblies is faulty, thefaulty assembly(ies) should be removed and returned to the Aviation Recorders fac-tory for repair or replacement. Attempts to repair any of these assemblies will voidthe warranty. Extreme care should be used when handling these assemblies.For repair service, ship units to:L--3 Communications, Aviation Recorders6000 East Fruitville RoadSarasota, FL 34232 USAAttn: Repair DepartmentTel: (941) 377--5558Fax #: (941) 377--5585CAUTION: THE L--3 ProTec CIRCUIT BOARDS ARE SUSCEPTIBLE TOELECTROSTATIC DESTRUCTION (ESD).

Marine SystemsAviation RecordersRev. 02 Page 1--8July 29/03Automatic Identification System1.3. AIS Description1.3.1. Compact DesignThe completely self--contained L--3 ProTec is the most compact AIS unit available onthe market today with outside dimensions of 6.5” W (16.5 cm) x 3.4” H (8.6 cm) x7.4” D (18.8 cm). It is easily mounted on any surface using either a trunion bracketor flush--mount bracket. The data port on the faceplate provides for easy connectionto any external display in either mounting configuration.1.3.2. Integral Minimum Keyboard Display (MKD)In line with the compact design, the L--3 ProTec is a single--box design incorporatingan integral MKD which is fully IMO compliant. The interface includes a of 2.58” L (6.5cm) x 1.16” H (2.9 cm) (160 x 64 Dots) backlit LCD screen for displaying alphanu-meric text and a multifunction keypad. The closest three vessels within AIS rangewill be displayed with each vessel identified by MMSI and ship name and will displayboth range and bearing to each vessel.The interface has been designed to facilitate data entry and retrieval with a minimumof keystrokes. It also includes a Pilot port designed to allow any user to quickly andeasily attach a portable AIS--compatible display system directly to the AIS trans-ponder for display of the AIS data. This display system can consist of any systemwhich recognizes the NMEA AIS string whether it’s installed on a handheld PC, lap-top PC, or dedicated display.1.3.3. Integral GPSThe L--3 ProTec includes an internal GPS receiver card. The internal GPS providestiming data required for synchronization of transmission. By specifications, ship posi-tional information in NMEA format is to be fed to the transponder from the ships ex-ternal electronic position indicating system through the supplied data cable. The in-ternal GPS requires a dedicated GPS antenna to be mounted on the superstructureand the appropriate connections are supplied on the transponder unit back panel.1.3.4. Data InterfaceEach transponder will be delivered with an IEC--specified NMEA standard data cablerequired to interface to ship’s sensors and external display. The description of thisinterface cable is given in the Installation Section of this manual. The standard kitincludes an eight (8) ft. (2.5 meters) cable and a terminal block to facilitate the finallinkup to the ship’s navigational instruments.

Marine SystemsAviation RecordersRev. 02 Page 1--10July 29/03Automatic Identification System1.3.6. Operational ModesThe ProTec AIS is designed to operate in each of three modes: Autonomous andContinuous, Assigned and Polled which are defined below.1.3.6.1 Autonomous and ContinuousThis is the default mode. The ProTec AIS will determine its own schedule for trans-mission of position and identification and will automatically resolve scheduling con-flicts with other stations using the Self Organized Time Division Multiple Access(SOTDMA) methodology.1.3.6.2 AssignedThe ProTec will automatically switch to assigned mode when it is commanded by acompetent authority, such as a base or repeater station, to transmit on a specifictransmission schedule. In this mode, the ProTec allocates the defined slots and be-gins transmitting on these slots. It will continue to transmit in these slots with a zeroslot time--out and a zero slot offset, until those slots have been removed from thetransmission schedule. The assigned slots use the SOTDMA access scheme, withthe time--out value set to the assigned slot time--out. The assignment terminateswhen the slot time--out reaches zero of any assigned slot, and the ProTec returns toautonomous and continuous mode.1.3.6.3 PolledThe ProTec AIS will transmit a response to DSC interrogation messages from a shipor competent authority and respond back on the same channel without interferingwith either of the other two modes. When an automatic response is required, trans-mitted responses will be made on channel 70 unless the unit is instructed to transmiton another channel. The ProTec is inhibited from transmitting on the AIS 1 and AIS2 channels. If and when frequency channels other than channel 70 are used forDSC transmissions, the receive capability of TDMA operations should not beimpaired more than it would be if all DSC messages were transmitted on channel70.1.3.6.4 InitializationThe ProTec AIS will enter into an Initialization mode at Power--Up during which it willmonitor the TDMA channels for one minute. During this initialization period, a dy-namic directory of all users in the system will be created which includes user ID’s,slot assignments, positions, and other transmitted data. After this initialization periodof 1 minute, the ProTec will enter the required operational mode and begin transmis-sion of the AIS data on the required schedule.
Marine SystemsAviation RecordersRev. 02 Page 1--11July 29/03Automatic Identification System1.3.7. DSC FunctionalityThe Assigned and Polled operational modes are activated through a DSC messagetransmitted by the competent authority. In order to provide for this, the ProTec AIScontains a dedicated DSC receiver that is tuned to channel 70. DSC messagesoriginating from shore stations of competent authorities will define regional AIS fre-quencies, regions of coverage, required transmission schedule and/or interrogationrequest. The ProTec AIS will respond back to such DSC interrogations on the fre-quency specified in a manner such that it does not interfere with the TDMA transmis-sions by interleaving the transmission between TDMA transmissions. The DSC re-sponse will be made after a random delay of 0 -- 20 secs provided the signalingchannel is clear and the TDMA transmissions are not interrupted.1.3.8. AIS Broadcast ParametersA Class A AIS unit broadcasts the following information every 2 to 10 seconds whileunderway, and every 3 minutes while at anchor at a power level of 12.5 watts. Theinformation broadcast includes:FMMSI number -- unique referenceable identification.FNavigation statusFSpeed over ground -- 1/10 knot resolution.FPosition accuracy -- differential GPS.FLongitude -- to 1/10000 minute and Latitude -- to 1/10000 minute.FCourse over ground -- relative to true north to 1/10th degree.FTrue Heading -- 0 to 359 degrees derived from heading sensor.FTime stamp -- The universal time to nearest second that this informationwas generated.In addition, the Class A AIS unit broadcasts the following information every 6minutes:FMMSI number -- same unique identification used above, links the dataabove to described vessel.FIMO number -- unique referenceable identification (related to ship’sconstruction).FRadio call sign -- international call sign assigned to vessel, often used onvoice radio.FName -- Name of ship, 20 characters are provided.FType of ship/cargo -- there is a table of possibilities that are available.

AIS FrequenciesThe International Telecommunications Union World Radio Conference in 1997 desig-nated two VHF radio frequencies: 161.975 MHz (AIS1, or channel 87B) and 162.025MHz (AIS2, or channel 88B) for AIS. In the US, the first channel is owned by Mari-TEL, a public coast station operator, and the second by the federal government. TheUSCG signed a Memorandum of Agreement with MariTEL for use of AIS 1, and hasauthority from the National Telecommunications and Information Administration touse both AIS1 and AIS 2 US--wide for AIS operation. The USCG has asked the Fed-eral Communications Commission to authorize any US vessel to operate AIS onthese two channels under its existing ship station license. The FCC released a No-tice authorizing operation of AIS under a ship’s existing station license.

Marine SystemsAviation RecordersRev. 02 Page 2--3July 29/03Automatic Identification SystemProTec AIS Operation2.1. OperationThe L--3 ProTec has been designed to require minimal user interaction during nor-mal operation. The interface consists of an integral alphanumeric display with alpha-numeric keypad providing for data entry, retrieval and display.2.1.1. Minimum Keyboard DisplayThe L--3 ProTec includes and integral MKD which is fully IMO compliant. It is recom-ended that the MKD should not act as the primary display due to limitations indata presentation options. It should be used for configuration of the hardware andentry of vessel and voyage specific data, which is required infrequently. It may alsoserve as a backup display if the external display were to malfunction. L--3 stronglyrecommends that the AIS Target Display Software (TDS) be used as the primary AISdisplay system and this software is available from the hardware supplier. TDS is abasic yet powerful graphic display software compatible with Windowstwhich pro-vides numerous display options for the AIS data. Contact L--3 Communications forfurther information and acquisition. The front face of the L--3 ProTec contains the fol-lowing controls.communicationsPower/DimStatus LightPilot PortDisplay WindowFigure 2--1. AIS Transponder
Marine SystemsAviation RecordersRev. 02 Page 2--4July 29/03Automatic Identification System2.1.1.1 Power/Dim ControlA single control knob controls both the on/off function and backlighting level for theLCD. To turn the unit ’On’, rotate the knob clockwise. To turn unit ’Off’ rotate counter-clockwise fully. The degree of rotation determines the brightness of the LCD back-light and rotation to the right will dim the backlighting.2.1.1.2 Liquid Crystal DisplayThe display is an alphanumeric LCD with backlighting which will display data entryforms and AIS target data for the nearest three vessels.2.1.1.3 Key PadThe keypad contains dedicated function buttons and alphanumeric buttons whichallow for data entry and retrieval.2.1.1.4 Pilot PortThe Pilot Port is an IEC high speed (38400 kbs) data port which can be used to con-nect any external display such as an ECS, or other PC--based software package.2.1.2. Keypad DescriptionThe keypad allows the user to access the menu system built into the transponderinterface. The keys are defined below:NAV AIS Target Data DisplayPressing this button will bring the user to the main default screen whichwill display the AIS target data for the nearest three vessels, or allows theuser to switch back to the “Own Ship” display if the nearest three vesselsare already displayed.ENT Enter KeyAllows user to enter Edit mode, or to save data if already performing anEdit operation.CLR Clear KeyUsed to clear data from a data entry field before entering new data .Pressing once will clear the entire field.Directional ARROW KeysUsed to navigate between data entry fields on a data entry form and scrollright/left and up/down in an alphanumeric display field. When in Closest

(The MMSIscreen will always be displayed for a vessel if the ship name is not known.FNC Function KeyUsed as the initial key in a key sequence to access the various secondaryfunctions of the interface.CAN Cancel KeyUsed to cancel any edit made in a data entry field and revert data back topreexisting data.MSG Message KeyUsed to access the text messaging window, in order to send Safety TextMessages.ESC Escape KeyWill bring user up one level on the menu system.The blue text above some identify the secondary definitions for each button. Thesesecondary definitions are activated by pressing of the FNC button in a key se-quence.SETUP Enters the system configuration menu system.HOME Returns cursor to start position in a data entry fieldEND Returns cursor to end position in a data entry fieldALL Will clear all contents of a data entry field when preceded by the FNC key.The alphanumeric keypad is used to enter both numbers and letters. When alphanu-meric text entry is expected, the nonnumeric options are presented before the nu-meric value of the key. For example, the number “2” key provides for entry of “A”,“B”, and “C”. When the cursor is positioned in a display field location that expects analphanumeric character, the first press of the “2” key will result in the display of an“A”. Another press (in a fairly short time) will cause a “B” to be displayed. The nextpress shows a “C”, while the forth press shows a “2”.Repeated key presses will result in cycling through the character options repeatedly.When the operator stops pressing keys for longer than the preset timeout, the lastvalue is retained and the cursor moves to the next location in the field. Pressing adifferent key forces acceptance of the last character for the field and moves the cur-sor along.

Marine SystemsAviation RecordersRev. 02 Page 3--4July 29/03Automatic Identification System3.1.1. TransponderThe L--3 ProTec is a single box design which is easily installed into any existingbridge layout. The compact design requires minimal clearance (refer to Figure 3--2and Figure 3--3) and can be mounted in a trunion bracket or mounted flush using theavailable flush--mount bracket. Install the transponder is as follows:(1) Mount the transponder in a position which provides easy access to the key-board and display. If using the trunion bracket, the mount itself may be used tomark the screw holes on the mounting surface. When locating the transponder,consider that the IMO mandates that the AIS keyboard and display be easilyaccessed from a navigable position on the bridge.(2) If used, Mount the transponder in the trunion utilizing the trunion knobs pro-vided, otherwise mount transponder in flush mount bracket.(3) Locate and mount the terminal block or junction box in a position near thetransponder. The IEC cable provided with the unit is 100 inches (2.5 m) longand the terminal block should be located to take this into account. Locate theterminal block in a fashion which allows for easy access to the terminals formaking the connections to required input/output feeds.(4) Refer to Figure 3--4. Connect the transponder power cable to the power con-nection on the Transponder and connect to the ships 12--24 Vdc power supply.The “Red“ lead goes to positive and “Black“ to negative. Ensure proper groundwire attachment to ships structure.The other two leads can be used to connect to an external alarm system. Thisalarm system can provide an audio and/or visual alarm in the event of an inter-nal system malfunction, or if the AIS loses power or is turned off.For steps (5) through (7) refer to Paragraph 3.1.2.(5) Connect the IEC cable to data port on back of Transponder using J4 connectorprovided.(6) Lead data cables from Gyrocompass data output port and ship’s DGPS dataoutput port.

Marine SystemsAviation RecordersRev. 02 Page 3--9July 29/03Automatic Identification System3.1.2. Connecting the IEC Data Interface CableThe AIS Transponder receives data from the ship’s sensors through a data interfacecable which is connected to the back of the transponder through a data port. IMOregulations require that the ship heading, speed--over--ground (SOG), course--over--ground (COG), rate--of--turn (ROT) and position be transmitted from the AIS. In or-der to meet these requirements, the L--3 ProTec provides six (6) data channels toallow the AIS to be connected to the ships Gyrocompass and DGPS system in ac-cordance with NMEA 0183.The L3 AIS is shipped with one IEC interface cable P/N 024--M0088--01. All IEC/Pi-lot communications with the AIS is referenced with the L--3 ProTec considered the“MASTER” in that transmit data is OUTPUT from the L--3 ProTec, and receive data isINPUT to the L--3 ProTec. All channels are isolated with individual shielded twistedpair cables. Refer to Figure 3--7. The IEC connector (J4) is located on the back ofthe L--3 ProTec. (Refer to IEC 61993--2 annex D. and NMEA 0183) IEC channels 1,2, and 3 are RECEIVE ONLY sensor inputs. Differential data (RS422) is received oneach of these channels and internally converted to TTL for input to a standardUART. Channels 4, 5, and 8 are all RS422 interfaces. IEC channels 4 and 5 areTRANSMIT/RECEIVE channels for AIS data. IEC channel 8 is the AIS long rangeport.3.1.2.1 Data ChannelsData enters the Transponder through six (6) available data channels. Three datachannels are low speed unidirectional (4800 baud) channels suitable for data inputto the transponder. The other three data channels are high speed bidirectionalchannels (38400 baud) which support both input and output to/from the transponder.The channels are described below by channel number and type. Suggested uses ofeach channel are provided but it is not required that a user define the channels inthis fashion. The internal software in the transponder is able to distinguish the typeof data feeding from each channel provided all data streams subscribe to the IEC61162 format (NMEA 0183).Table 3--1.

(Refer to Figure 3--6,Figure 3--7 and Figure 3--8.) The IEC data cable is shielded and contains threesmaller diameter cables, each of which is also shielded. Each of these smallercables contains three shielded twisted pairs (STP) each and each STP includes adrain wire. A low speed unidirectional (input only) data channel (4800 kbs) is carriedthrough one STP, and a high speed bidirectional (input/output) data channel (38400kbs) will require two pairs.P1--Connector, Cannon p/n 2PA31PMetal or metalized plastic backshell,Cannon p/n DA121073--150 or EquivalentThumbscrew, Cannon p/n 250--8501--013or EquivalentCable, ECS p/n 622818Marker, Brady p/n PWC--PK3or EquivalentPin 1Pin 10Pin 31Pin 22100 in. ¦2in. 2.5 m ¦.05 m10 in. ¦2in. 25 cm ¦5cmFigure 3--6.

Marine SystemsAviation RecordersRev. 02 Page 3--13July 29/03Automatic Identification System3.1.2.3 Terminal BlockEach Transponder will come shipped with a 31 pin terminal block. A terminal block isthe preferred installation method for completing the data interface (NMEA) becausedata output from a ship sensor ( dGPS, ROT, Gyro) may not subscribe to a standardpinout definition. As such, each installation may require that the installer identifyand cross reference the sensor pinouts with the IEC pinouts, which is a well definedstandard pinout description. The terminal block allows for greater flexibility in com-pleting the connection to the ship’s sensors.A junction box may be made available which terminates the data cable on the termi-nal block and provides serial connectors to allow for easy connection to ship sen-sors. However, the installer will need to confirm the pinout definitions for the sensoroutputs before completing the connection correctly.To complete the data connection to the ship’s sensors, perform the following:(1) Connect the data cable to the back of the transponder unit.(2) Feed the data cable into the console to the position in which the terminal blockwill be placed.(3) Locate an ideal position for the terminal block.FProtected from weather.FProtected from high heat.FProtected from accidental contact with conductive material.FWithin 100 inches (2.5 m) of the transponder due to IEC data cable length.FGrounding of terminal block to ship’s structure.FNeed to feed cables from navigational sensors.(4) Mount the terminal block to the ships structure with self tapping screws(5) Ground terminal block to ship’s structure using grounding cable provided.(6) Connect each wire to the correct terminal block position. Use the table belowwhich gives the IEC pin ID (and color code) and identifies the correct terminalblock position ID.NOTE: The metallic shielding of each of the three shielded cablescontaining the twisted pairs must be connected to the ter-minal block using the shield drain wire connected to theshield. The shields from Cables 1 and 2 do not have to beconnected. The shield from Cable 3 must be connected toTB pin ID 30, which is grounded to the ship’s hull.

Marine SystemsAviation RecordersRev. 02 Page 3--15July 29/03Automatic Identification System3.1.3. Installing the VHF AntennaInstallation of a VHF antenna is as important to reliable communications as thetransceiver itself. It is recommended that a high quality antenna be purchased froman established source and that all manufactures instructions be followed with partic-ular attention to cable routing and connector installation. Some important consider-ations in antenna installation are:FIn general, antennas should be located as high as practical on the vesseland separated as much as possible from each other.FThe VHF antenna should be placed in an elevated position with a mini-mum of 2 meters clearance from any construction that is made with con-ductive material. In addition, it should not be installed close to any largevertical obstruction, and the VHF antenna should have a 360°line of sightto the horizon.FIt is preferable that the VHF antenna is installed at least 3 meters awayfrom high power energy sources such as radar and other transmitting ra-dio antennas, and out of the transmitting beam.FThere should not be more than one antenna on the same level. The AISVHF antenna should be mounted directly above or below the ship’s prima-ry VHF radiotelephone antenna, with no separation and with a minimum of2 meters vertical separation. If the VHF antenna is located on the samelevel as other antennas, the distance between them should be at least 10meters.To install the VHF antenna, perform the following:(Refer to Figure 3--9 and Figure 3--10.)(1) Position the antenna mounting bracket on a rigid and structurally sound sur-face. In general, two bracket types are available, a rail mount and a flat (pad-eye) mount. Some mounts have a ratchet mechanism which allows them to bemounted on an inclined surface. Whichever mount is used; ensure the qualityof the mount. L--3 recommends a heavy gage stainless steel mount be used inthe mounting of the antenna.(2) Install the antenna on the antenna mount.(3) Run the coaxial cable from the antenna to the transponder location. Use onlyhigh quality RG8X or RG214 coaxial cable and keep cable length as short aspossible to reduce signal attenuation.(4) Trim cable to length leaving a few inches slack at the transponder.(5) Attach the connectors to the end of the coaxial cable.(6) Connect the cables to the transponder. Soldering the connection is notrequired.
Marine SystemsAviation RecordersRev. 02 Page 3--16July 29/03Automatic Identification System3.1.4. Installing the GPS AntennaThe correct installation of a GPS antenna is crucial to the operation of the trans-ponder because the internal transmission synchronization relies on the accuracy ofthe time signal obtained from the GPS. It is recommended that a high quality GPSantenna be purchased from an established source and that all manufactures instruc-tions be followed with particular attention to cable routing and connector installation.Some important considerations in GPS antenna installation are:FGPS antennas should be located to provide a clear, unobstructed view ofthe sky.FGPS signals can be affected by RADAR and SATCOM transmissions. Assuch, GPS antennas should be positioned below and at least 5 metersaway from RADAR and SATCOM antennas and outside of the beam path.FGPS signals can also be affected negatively by VHF and HF transmis-sions, and the GPS antenna should be positioned at least 3 meters fromthese types of antennas.FThe GPS antennas can be flat mounted onto any surface but it is recom-mended that it be elevated from the deck surface (20--30 cm) to preventice or spray from negatively impacting the signal reception.FRecently, it has been identified that certain makes/models of TV antennascan drastically interfere with GPS reception. As such, the installer shouldplace the GPS antenna as far away from any shipboard TV antennas aspossible and confirm that any antennas used on board are not ones whichhave been exhibited GPS interference problems.To install the GPS antenna, perform the following:(Refer to Figure 3--9 and Figure 3--10.)(1) Position the antenna mounting bracket and/or antenna mast on a rigid andstructurally sound surface.(2) Install the antenna on the antenna mount.(3) Run the coaxial cable from the antenna to the transponder location through anexisting throughhull. Use only high quality RG59 coaxial cable and keep cablelength as short as possible to reduce signal attenuation.(4) Trim cable to length leaving a few inches slack at the transponder.(5) Attach the connectors to the end of the coaxial cable.(6) Connect the cable to the transponder. Soldering the connection is not required.
