AE–2000 Manual Typical NAVTEX Message Screen 1-2 1. Typical NAVTEX Message Screen (continued – 2/6) 1.1. Introduction (continued – 2/5)  Message Scrolling Keys The keys that can be used to manually scroll messages across the current screen are indicated.  : Line–by–line scrolling by pressing /  : Message–by–message scrolling by pressing/ NOTE: When a type–D message (SAR, piracy and armed robbery information) is received, automatic scrolling will be disabled until the user acknowledges the message with or with a software command from an IBS /INS terminal via the rear–panel RS–422 connector. See paragraph 7.4 for details.  Receiver Operating Status Indication The current status of receiver operation is indicated here.  ABORTED: The receiver has failed to lock onto the current transmission, due, for example, to weak signal level or noise interference. No message will be displayed or stored. NOTE: Signal propagation conditions change greatly with time. You might not be able to receive a signal in the daytime that can be received at night; this is normal and should not be considered as a sign of receiver malfunction.  ACQUIRING: The receiver is currently in the process of locking onto the start of the current message transmission.  LOCKED: The receiver has locked onto current NAVTEX transmission, allowing a message to be received. As soon as the equipmet starts receiving the message, this indication will be replaced by RCVNG MSG.  RCVNG MSG: The receiver is properly receiving a message after locking onto current transmission. This blinking indication will stay until the end–of–message code NNNN () is received. NOTE: Whether to display or output the message to external devices depends on the character error rate (CER, ) and on the selection/rejection settings to be made via the procedure in paragraph 4.8.  STANDBY: The receiver is idling, waiting for a NAVTEX message transmission to begin. Most stations transmit messages every 4 hours.  Operating Status Line The current status of receiver operation, text scroll keys, etc. are indicated here. Examples:  1ST RCVR MSG: Message received on the first receiver is currently displayed.  2ND RCVR MSG: Message received on the second receiver (490 or 4209.5 kHz) is currently displayed.  : Message can be scrolled line by line by pressing /.  STANDBY: Receiver is idling, waiting for a NAVTEX message transmission. See  above for details. (continued on next page) 1. Typical NAVTEX Message Screen (continued – 3/6 ) 1.1. Introduction (continued – 3/5 )
AE–2000 Manual Typical NAVTEX Message Screen 1-3  Message Identification (Message ID) The ID of the currently displayed message is shown here. A red–colored ID represents a warning message. A message ID consists of the following elements: station ID, message type, and message serial number, as in the following example. Figure 1-2 NAVTEX Message ID Format – Example *1: ID of the transmitter from which the message was received. Examples: J in NAVAREA : Gislövshammar, Sweden F in NAVAREA : Cape Cod/Boston, U.S. I in NAVAREA : Las Palmas, Spain *2: Type (category) of this message (subject indicator) Examples: A: Navigational warnings B: Weather warnings D: Search and rescue, piracy and armed robbery information *3: Serial number of this message Each message within the same category group is allocated a serial number between 00 and 99 by each transmitter. A message with number 00 is always received on each transmission regardless of rejection settings, and will be displayed and stored in memory.  Alarm Tag IIALARM!III This tag represents a visual alarm and is turned on when a NAVTEX message of one of the following types has been received.  Type–A Message: Navigational warning (initially disabled)  Type–B Message: Weather warning (initially disabled)  Type–D Message: Search and rescue, piracy and armed robbery information. All text characters will be displayed in red to distinguish it from other type alarm messages.  Type–L Message: Additional navigational warning (initially disabled) NOTE: When a type–D message has been received, an audible alarm will also be turned on, beeping at approx. 1–second intervals. To silence the alarm sound, press . A second keypress resets the alarm and removes the alarm tag. The alarm for the message types A, B and L is initially disabled. It can be enabled via SYSTEM MENU – 9:TURN ON/OFF MESSAGE ALARM. See paragraph 4.14 for details. (continued on next page) 1. Typical NAVTEX Message Screen (continued – 4/6 ) 1.1.

AE–2000 Manual Typical NAVTEX Message Screen 1-4 This indication ( tag) shows that the currently displayed NAVTEX text is a new message that you have not yet read or acknowledged. To acknowledge it, simply press  or , turning the tag off. If two or more new messages have been left unread, the following caution message will be displayed at the screen bottom, prompting you to read them. Press  again to display, or scroll the text up to, the next one by pressing /. The NEW MESSAGE tag for the current message will be automatically removed 24 hours after its reception, if it is left unacknowledged ( i.e. if is not pressed).  NAVTEX Message If message text exceeds the screen display area, you can scroll it line–by–line by pressing /. Holding down either key accelerates the scroll. To read other messages, press / (for message–by–message scrolling). Holding down either key accelerates the scroll. Type–D messages (SAR , piracy and armed robber y information) will be displayed in red. A new type–D message will remain fixed on screen until:  it is acknowledged by pressing  or by means of a *1software command through an INS/ IBS terminal interfaced to the rear panel RS–422 connector, or  another new type–D message is received on either receiver. *1: See paragraph 7.4.5 for details. NOTE: Forced carriage return  When the number of characters in a line exceeds 40, an internally generated carriage return symbol, shown above, will be automatically inserted in the 40th character position to divide the last word, forcing the rest of the characters in the word to shift to the top of the next line. This symbol will be replaced by an underscore ( _ ) (hex 5F ) when it is printed or output to an IBS / INS device via the RS–422 port.  End–of–Message Indication NNNN The appearance of these four successive N characters indicates the end of the currently displayed NAVTEX message. NOTE: Some messages including those from Chinese stations, end with NN ( 2 Ns) instead of NNNN (4 Ns), in which case, the equipment will consider that the transmission has not ended properly, and will not, therefore, display and store such a message, or will append it to a new message, if received within a specified period of time, and display the two messages combined. The RS–232C port (printer port) may be set to output such messages. See paragraph 4.9 for setting instructions. (continued on next page) 1. Typical NAVTEX Message Screen (continued – 5/6 ) 1.1.

AE–2000 Manual Typical NAVTEX Message Screen 1-5 the internal non–volatile memory.  *1STORED: The message has been stored. When message reception has been completed with a character error rate (CER) of 33% or less, the received NAVTEX message together with its ID will be stored in memory, making it possible to recall it onto the screen at a later time. If the same message is received with a lower CER on the next transmission, the previously stored message will be replaced with the new one. However, if the first message was received with a CER of 4% or less, message replacement will not take place on subsequent reception of the same message with a lower CER. When the CER exceeds 33%, the message and its ID will not be displayed and stored in memory, allowing a retransmission of the same message to be displayed and stored. *1: If the message selection/rejection settings are made so that a particular message type is rejected from storage, this indication will not be displayed regardless of a CER being smaller than 33%. See paragraph 4.9 for the related setting instructions.  Character Error Rate (CER) Indication CER is the percentage ratio of the total number of corrupt characters represented by asterisks (*) to the total number of characters received in a message, including control codes (sync. signal, carriage returns, line feeds, letter/numeral shift, etc.), If a message is received with a CER equal to or greater than 33%, it will not be displayed and stored in memory, allowing the same message to be received again on its next transmission. No CER reading will be available on the current transmission. See paragraph  for more information on CER.  Message Prompt Line This line indicates the receiver’s response for the user’s keypress or displays prompts related to reception of new or alarm NAVTEX messages on the first or second receiver, or related to message storage, like the examples below.  ALARM MESSAGE RECEIVED ON 2ND RCVR  MORE UNREAD ALARM *2MSG LEFT  2ND *3RCVR RECEIVED NEW MSG  MORE NEW MSG LEFT  STORAGE LIMIT IS REACHED  MEMORY FULL ! *4 [CLR] TO *5 ACKNLG. *2 MSG = MESSAGE, *3 RCVR = RECEIVER *4 [CLR] =  *5 ACKNLG = ACKNOWLEDGE 1.

Introduction Initially, all stored NAVTEX messages will be automatically erased one by one from memory on a first–in–first–out basis as the equipment continues receiving new messages after the message storage capacity limit (200 messages) is reached. If you wish to protect a specific message for permanent retention in memory, proceed via the steps given below. Up to 50 messages can be protected across each receiver screen, and are saved in a separate area of the non–volatile memory, allowing an additional 50 new messages to be stored in each of the first receiver and the selected second receiver. 3.8.2. Protecting Procedure Figure 3-10 Protecting a Specific Message from Automatic Erasure – Step 1 (1) Using /and/or /, display the message you wish to save. If two or more messages are being shown, the ID of that message should be brought to the top message line, as in the example at right. Figure 3-11 Protecting a Specific Message from Automatic Erasure – Step 2 (2) Press . This will attach a message protection tag (PROTECTED tag) to the message ID as in the example at right, indicating that the message is now protected against automatic erasure. NOTE: If the message you wish to protect is a new message, the NEW MESSAGE tag will be replaced with the PROTECTED tag. Storage Limit Indication Attempting to protect messages in excess 50 will cause the following error message to be turned on blinking in the message prompt line for a few seconds. 3.

AE–2000 Manual Customizing Operation via Menu System 4-6 4.8. Selecting and Rejecting Transmitters 4.8.1. Introduction Initially the equipment is set to *1display NAVTEX messages from all stations on the air within the coverage area, *1store those messages in memory and output them to the printer port (RS–232C), *2I/O DATA port and INS port (RS–422). There may be cases where you do not wish to display, store, or output future messages from specific transmitters that are not of your concern to your navigational needs. Carrying out the following procedure allows you to select or reject transmitters independently for message display and storage in memory, for message output to the printer port, and message for output to the INS port. A list of the transmitters that are currently rejected from display and storage can be checked by pressing  with the message screen showing. *1: A message will be displayed and stored in memory unless its character error rate (CER) exceeds 33%. CER is the ratio of the number of the correctly received characters to the number of corrupt characters per message. *2: The I / O DATA port (I/O DATA) outputs the same message output as the printer port. 4.8.2. Setting Procedure To reject a specific station, execute the following step–by–step instructions: (1) Highlight option “4: MAKE SEL/REJ SETTINGS” by pressing /, and then . This opens a submenu as shown below with the following options:  1: SYNCHRONIZE BOTH RECEIVERS: Applies same settings to both receivers.  2: FIRST RECEIVER (518KHZ): Makes settings for first receiver alone.  3: SECOND RECEIVER: Makes settings for second receiver alone. < CAUTION > There are NAVAREAs where the same ID is shared by two transmitters, one on 518 kHz and the other on 490 or 4209.5 kHz, located in two different countries in the same service area. In such cases, choosing option “1:SYNCHRONIZE BOTH RECEIVERS” will result in unintended rejection settings on either frequency.

If a problem persists, contact your dealer for assistance, giving as much information as possible about the symptom, self–diagnostic tests results (paragraph 4.13), power supply voltage, antenna configuration, operating frequency, control and menu settings used, serial number of, and *1software version (VER.) and revision (REV.) numbers of, your equipment. *1 The software version and revision numbers are displayed in the opening message window that appears briefly at power–up. Those data will also be displayed when the self–diagnostic tests are conducted (paragraph 4.13). < WARNING > HIGH VOLTAGES EXIST INSIDE THE EQUIPMENT CABINET. NO USER–SERVICEABLE PARTS ARE INSIDE THE CABINET. QUALIFIED PERSONNEL SHOULD MAKE IT SURE TO SWITCH THE EQUIPMENT OFF AND UNPLUG THE POWER CORD BEFORE OPENING THE CABINET FOR INSPECTION OR REPAIRS. 5.1. Power–Up Problems The following description of the symptoms assumes that the equipment was working correctly for some time after its initial installation. Symptom Suggested Solution The equipment cannot be turned on. 1. Check if the power cord is plugged into the three–pin rear panel connector ( POWER). 2. Check if the power cord is connected to the ship’s DC power source with the correct polarity. NOTE: Reversing the power cord polarity causes the fuse (3A) to blow. 3. Check the voltage of the power source. NOTE: The nominal power supply voltage is 24 VDC. The equipment works safely over the voltage range from 11 to 36 VDC. 4. Check the fuse inside the rear panel fuse holder. If it is found blown, replace it with a correct replacement ( 3A, 5.2X20mm). 5. If it blows again, unplug the active antenna cable from the rear panel connector, and then check if the problem persists. If it does not, suspect that the antenna amplifier or the cable developed a short. Replace the antenna and cable. 6. If replacing the antenna still does not correct the problem, suspect that either the power supply PCB or the DC/AC inverter PCB has become defective. Ask your dealer/qualified engineer to check each board by replacement. 7. If all attempts above fail, ask your dealer/qualified service engineer to replace the CPU PCB.
AE-2000 Manual User-Level Troubleshooting 5-2 5.2. No Message Reception The following description of the symptoms assumes that NAVTEX messages were properly received for some time after initial installation. Symptom Suggested Solution No messages can be displayed except for warning messages. No NAVTEX messages can be received, except for navigational warnings, weather warnings, SAR/piracy/armed robbery warnings or other warnings. 1. Check the current message rejection (RJ) settings by pressing . 2. Select all desired message types for display and memory storage, via the steps given in paragraph 4.9. No messages can be displayed from desired transmitters. No NAVTEX messages can be displayed from some transmitters at any time even if you are within the coverage areas. 1. Check the current station rejection (RJ) settings by pressing . 2. Select the IDs of all desired transmitters for display and storage in memory, via the steps given in paragraph 4.8. No messages can be displayed despite correct selection settings and appearance of “RCVNG MSG.” No NAVTEX messages can be displayed regardless of the correct display and storage selection (SL) settings for all desired messages or transmitters, or regardless of the “RCVNG MSG” status indication during reception. 1. The same message was received before or the currently receiving message has a character error rate (CER) > 33%. See subparagraphs ,  and  in paragraph 1.1 for details. 2. Run the self–diagnostic tests via the steps given in paragraph 4.13, and check if the receiver test result is “OK.” If the test result indication shows “FAILED,” suspect that the corresponding receiver PCB has become defective. Ask your dealer or qualified engineer to check all wiring harnesses to/ from the PCB and to replace the PCB if necessary. The chance of any receiver being out of tune is very small in normal usage. 3. Check if you are located within the service area covered by the ground wave of the desired station. The ground wave coverage normally extends to 200 – 400 nautical miles from each station during daytime hours. 4. Check the broadcast schedule of the desired station. Each station usually transmits messages for 5 to 10 minutes at intervals of 4 hours. 5. Check the active antenna unit and/or cabling by replacement. (continued on next page) 5.2. No Message Reception – 2/3
AE-2000 Manual User-Level Troubleshooting 5-3 Symptom Suggested Solution No messages can be received in the daytime. No NAVTEX messages can be received on 518 kHz or 490 kHz during daytime hours despite appropriate station and message type selection (SL) settings. 1. Check if you are located within the service area covered by the ground wave of the desired station. The area is normally 200 to 400 nautical miles from each station during daytime hours. At night, MF NAVTEX signals ( 518 / 490 kHz) can travel distances in excess of 1000 nautical miles depending on the season and ionospheric conditions. Nighttime signal propagation is usually unstable, changing greatly with the season. 2. Check the broadcast schedule of the desired station. Each station usually transmits for 5 to 10 minutes at intervals of 4 hours. Currently transmitting stations may be outside the coverage area. No messages can be received even during a broadcasting time and while in the service area. No NAVTEX messages can be received regardless of being in the service area of a currently transmitting station and of appropriate message type and station selection settings. 1. Check if the antenna cable is correctly plugged into the appropriate rear apron BNC connector receptacle. 2. Check if the connector (BNC) plug is properly installed onto the cable. Check also the coupling connectors, if used for cable extension. 3. Check by replacing the active antenna. The antenna preamplifier unit may have been destroyed by static discharges. If a correct replacement is not available, run at least 5 meters of insulated wire from the BNC connector’s center conductor as a temporary long wire antenna, and place it as high as possible from the ground level. < WARNING > DO NOT SHORT THE OTHER END OF THE WIRE ANTENNA TO GROUND, OR DAMAGE TO THE UNIT’S POWER SUPPLY WILL RESULT. 4. If replacing the antenna still does not solve the problem, check the voltage at the center conductor of each antenna connector. It should be 8V+ on the 490 and 518 kHz connectors, and 12V+ on the 4209.5 kHz connector. If no voltage is present or if it is extremely low, ask your dealer/qualified engineer to check the wiring to / from the power supply PCB first and to replace the PCB, if necessary. 5. If all attempts above fail to correct the problem, ask your dealer/qualified engineer to check the related connections to/from the CPU PCB first and to replace the PCB, if necessary. (continued on next page) 5.2. No Message Reception – 3/3
AE-2000 Manual User-Level Troubleshooting 5-4 Symptom Suggested Solution No messages can be received at any time on the first or the second receiver with a good replacement antenna plugged in, but the results of the self–diagnostic tests are “OK” for both receivers. No NAVTEX messages can be received at any time and anywhere on either the first or the second receiver after the antenna is replaced with one known to be good. The self–diagnostic tests (paragraph 4.13) show that both receivers are working properly. The symptom is an indication that the antenna circuit has become defective. 1. If the active antenna is used, replace it with one known to be good. 2. If a correct replacement antenna is not available, run approx. 5 meters of insulated wire from the center conductor of the appropriate connector as a temporary long wire antenna, and place it as high as possible from the ground level. < WARNING> DO NOT SHORT THE OTHER END OF THE WIRE ANTENNA TO GROUND, OR DAMAGE TO THE UNIT’S POWER SUPPLY WILL RESULT. 3. If replacing the antenna still does not solve the problem, ask your dealer/ qualified engineer to check the antenna coupler/selector circuit inside the rear apron for faulty or broken connections. No messages can be received at any time on the first or the second receiver with a good replacement antenna plugged in, and the results of the *self–diagnostic tests are “FAILED” for both receivers. * 30 minute warm–up period required before test. 1. The symptom suggests that both receivers have got out of alignment. Ask your dealer/qualified engineer to check the connections to/ from the receiver PCBs and/or replace the PCBs. 2: The CPU PCB has also become defective and/or some of the internal connections to the PCB have become faulty or broken. Ask your dealer/ qualified engineer to check the related wiring harnesses to/ from the CPU PCB first and to replace the PCB, if necessary. 5.3. Message Storage Problems Symptom Suggested Solution Some stored messages disappear from memory after some time. Messages will be erased from memory after 60 hours, unless they are protected from automatic erasure. Put the “PROTECTED” tag to each desired message via the steps in paragraph 3.8. None of the received messages is stored after power–off. The symptom indicates that the memory backup circuit on the CPU PCB is failing. Ask your dealer or qualified engineer to replace the CPU PCB. All messages disappear from memory after continued power–off for some time. The memory retains stored messages for at least 10 days after power–off. Print out desired messages using an optional printer before switching the unit off for extended periods of time continuously. 5.4. Poor Reception

AE-2000 Manual Installation 7-1 7. Installation 7.1. Receiver Cabinet Installation 7.1.1. General Precautions The receiver cabinet is constructed to withstand the humid and corrosive marine environment, but is designed to be installed or operated inside the wheelhouse or chartroom. The cabinet is a “protected” category product under the IEC 60945–2002 standard, and is not waterproof. Serious damage will result to the electronics inside the cabinet when it is exposed to salt water spray or splash. Additional Requirements: (1) For long term trouble–free service, the proposed site for installation should be:  dry, well–ventilated and free as much as possible from shocks and engine vibrations.  away as much as possible from high temperature outlets (such as exhaust fans and heaters), and as much as possible from areas where the unit is likely to be constantly exposed to direct sunlight. (2) To prevent reception of weak NAVTEX signals from being interfered with, the unit should also be located away as much as possible from other onboard electronics, especially those emitting pulsed signals, such as echo sounders and radars. 7.1.2. Mounting the Receiver Cabinet The receiver cabinet is primarily designed to be mounted on a tabletop with the mounting bracket supplied and weights approximately 3.7 kg in total. The dimensions necessary for installation are given in Figure 7–2. Provide sufficient clearance behind the cabinet for cabling termination and maintenance checks. Using a total of four appropriate wood screws or bolt/nut combinations through its four mounting holes (9 mm in diameter each), secure the bracket to the selected site. Make sure that the mounting surface is strong enough to support the unit against shocks or vibrations that are likely to be encountered with the ship in motion. Compass Safe Distances ( in energized condition):  Receiver Cabinet alone: 0.60m ( standard), 0.40m ( steering)  Cabinet with Bracket: 0.80m ( standard), 0.45m ( steering) < WARNINGS > 1. DO NOT PLACE THE UNIT IN AN UNVENTILATED, SEALED ENCLOSURE, SUCH AS A THEFT–DETERRENT CABINET, OR OVERHEATING AND MALFUNCTION WILL RESULT. 2.

AE-2000 Manual Installation 7-3 long wire is to be used permanently, it should be insulated and at least five meters long. 7.2.1. Installation Site Requirements Active Antenna For best results and a prolonged service life, the active antenna unit should be installed:  at a site free from continuous, heavy shocks and vibrations,  away as much as possible from the feedpoint or radiating elements of HF/MF communications antennas, radar scanners and INMARSAT antennas, and  away as much as possible from, and above, any metallic obstructions. < WARNING > LOCATING THE ACTIVE ANTENNA CLOSE TO THE FEED POINT OR RADIATING ELEMENTS OF AN HF/MF TRANSMITTING ANTENNA CAN DESTROY THE PREAMPLIFIER IN THE CYLINDRICAL HOUSING. Long Wire Antenna  A long wire antenna should be of insulated type and at least 5 meters long. Bare wire can short–circuit the antenna to ground and must not be used. Before connecting the wire to the appropriate rear apron antenna connector, ask your dealer/qualified service engineer to change the internal wiring (two jumpers) on each receiver PCB in the cabinet and on the frequency converter board in the rear apron so that an input impedance match is achieved and that no DC voltage is present on the connector’s center conductor.  For best results, the wire should be raised as high as possible from the ground, and as much away as possible from nearby walls or surrounding structures as well as from the onboard devices listed above, or very poor, noisy reception will result. 7.2.2. Precautions for Cabling  To minimize the effect of interference from other onboard electronics, the coaxial cable from the antenna unit should not be run close to, and in parallel with, transmit antenna feed lines, radar waveguides, echo sounder transducer cables, control cables, power cables, etc. from such equipment. The same requirements apply to the routing of the long wire antenna.  If the cable is extended with coaxial connectors ( e.g. PL–258/PL–259 pairs), be sure to make the junctions waterproof using self–bonding tape or other appropriate sealant. < WARNING > THE CENTER CONDUCTOR OF THE COAXIAL CABLE IS AT +8 VDC (OR AT +12V WHEN WORKING ON 4209.5 KHZ) WITH THE EQUIPMENT SWITCHED ON. DO NOT SHORT THE CENTER CONDUCTOR TO GROUND OR DAMAGE TO THE POWER SUPPLY PCB CAN RESULT. < CAUTION > Water intrusion into the coax cable will seriously degrade the reception performance.

AE-2000 Manual Theory of Operation 8-1 8. Summarized Theory of Operation 8.1. What is NAVTEX? NAVTEX, a system of broadcast and automatic reception of global maritime safety information by means of direct display/printing telegraphy, is part of the *1GMDSS infrastructure, defined by *2IMO Assembly resolution A.706 (17). Broadcasting is accomplished by a worldwide network of dedicated coastal stations regularly sending weather information, navigational warnings, search–and–rescue (SAR) information and other related messages, all in an easy–to–read text format, to mariners free of charges. 8.2. Operating Frequencies At present three frequencies are officially allocated by the *3ITU for NAVTEX broadcasting service: 518 kHz, 490 kHz and 4209.5 kHz. All *4SOLAS convention vessels are required to carry a receiver dedicated to receiving NAVTEX transmissions automatically on all the above frequencies. Transmissions on 518 kHz are in English and of general interest to vessels navigating international waters, while the 490 kHz service is primarily targeted at those working most of the time in areas close to transmitting stations, providing more localized information in national languages. Some stations also broadcast information to local users on 4209.5 kHz. Stations on each frequency transmit NAVTEX messages usually for a period of 10 minutes on a time–sharing basis to avoid cross–station interference. 8.3. Service Area The coverage area of a 518 kHz station is normally 200 to 400 nautical miles in daytime hours, depending on the transmitting power level, and a signal travels along the surface. At night some of the signal often travels more than double the daytime coverage by being reflected a number of times between the surface and the ionosphere, a band of ionized atmospheric layers 50 to 400 km above the surface. The 490 kHz service area is less than the 518 kHz coverage due to lower transmit power levels, but the nighttime coverage often extends greatly because of ionospheric reflections. The 4209.5 kHz broadcast, though catering mainly for inshore users and covering much less areas in the daytime, can be received from more than 1000 miles away during hours of darkness. 8.4. Error Correction Signal propagation conditions constantly vary with time of the day and also with the season. The signal arriving at the receiver can be corrupted or distorted at any time by static discharges, natural noise, abnormal solar activity, unstable ionospheric conditions, interference between the signal coming directly from the transmitter and the one reflected from the ionosphere, etc. It is therefore likely that a vital NAVTEX message can be missed due to signal corruption or distortion at the receiving end. In order to ensure that each message is properly received within its intended area of coverage, a station sends out the same message twice, some hours apart, each with its identification code ( known as B1 character), message type code ( B2 character) and a two–digit serial number (B3B4, ranging 00 to 99). In addition, the system employs a mode of transmission called forward error correction (FEC), transmitting each alphanumeric character in the message twice at very short intervals. If the same character is received twice, the receiver considers it to be a true character. If either of the received characters is different or corrupted, the receiver treats it as an invalid letter, and displays or prints an asterisk (*) in its place, thereby securing the reliability of a received message. (continued on next page) 8. Summarized Theory of Operation (continued – 2/6 )
AE-2000 Manual Theory of Operation 8-2 8.5. NAVTEX Receiver – General A NAVTEX receiver that complies with the relevant IMO resolutions and regulations for wheel mark certification is programmed to automatically receive and display/print a message, and avoids a repeated reception of the same message by checking the ID and numbering of each message. Using the ID and message type data attached to each message, the user can also program the receiver to reject certain transmissions and message types that are not of importance while in the current area, except for SAR and other urgent warning messages classified as type D messages. An audible and visual alarms are automatically triggered upon reception of such a message. To silence the alarm, the user must manually, or via an appropriate command from an INS terminal, acknowledge the message arrival. Received messages are either printed on paper (for a receiver with a built–in printer) or displayed on a screen with memory for storage and retrieval (for a receiver with an integral LCD screen). 8.6. The AE–2000 NAVTEX Receiver The AE–2000 receiver has two built–in receiver, with the first receiver devoted to receiving 518 kHz broadcast and the second receiver receiving either 490 kHz or 4209.5 kHz signal as selected by the user. Received messages are displayed across an 8–inch liquid crystal display (LCD) and stored permanently or temporarily as specified by the user. Up to 200 messages, each with an average of 500 characters, received on the first and second receivers are separately stored and then automatically erased from memory 60 hours after the time of reception on a first–in–first–out basis. However, up to 25 messages can be protected against automatic erasure, and are stored in a separate area of the non–volatile message memory, in which case an additional 50 new messages can be stored in memory across each receiver screen. When a transmission occurs on the first and second receiver frequencies at the same time, the equipment receives both signals, displaying the first receiver message while storing the second receiver message in memory for later retrieval. An appropriate caution message shows up in the screen bottom prompt line to indicate the reception of a new NAVTEX message on the second receiver. Reception of a type–D message (SAR, piracy and armed robbery information) activates the audible and visual alarms. The received message text then is shown in red, making it easy to discriminate it from navigational (type–A) and weather (type–B) warnings. The audible alarm also sounds differently to indicate that a type–D message has been received. The alarm can be acknowledged remotely by an INS terminal connected to the RS–422 port on the rear panel. The stored messages can be output via three interface ports mounted on the rear panel for IBS/INS or other onboard applications The user can specify the ID, frequency and type of the messages you wish to output.

Operating Principle of AE–2000 Figure 9–1 shows interconnections between the printed circuit boards (PCBs) comprising the AE–2000 system and interface connections from the PCBs to data input/output ports and peripheral devices. Figure 9–2 is the schematic of the antenna selector which allows selection of the desired antenna from a single keystroke on the keypad. To follow the circuit description below, see also the schematics of the receivers, CPU PCB and power PCB attached. Receiver Circuit To receive the three NAVTEX frequencies (518 kHz, 490 kHz and 4209.5 kHz), the system incorporates two independent receivers (first and second receivers) plus a frequency converter. The 518 kHz international broadcast is picked up by the first receiver (NT–2000A), and the 490 kHz national broadcast, by the second receiver (NT–2000B). The second national broadcast frequency of 4209.5 kHz is first converted down to 490 kHz by the frequency converter (N501–F/ C–A) and then fed to the second receiver. Each receiver is of straight amplifier type, consisting of two stages ( field–effect transistors V6 and V7) of amplification, followed by an IC amplifier (U1) and an amplitude limiter ( diode pair V8 and V9 ). Located at the end of the amplification chain is an FM detector that consists of crystal–controlled oscillator B1, its associated parts and part of the IC circuitry), which demodulates a frequency–shifted (±85 Hz) RF NAVTEX signal into a stream of baseband DC pulses at 100 baud using a quadrature detection technique. The detected output is then fed to the CPU via opto–isolator K2. To test whether each receiver is functioning properly, a NAVTEX signal generator is provided on the PCB, consisting of quartz crystal B2, IC (N1) and their associated parts. When the self–diagnostic test function is activated via the menu, the CPU PCB supplies a test signal (modulating signal) to the generator via opto–isolator K4 and transistor switch V13, allowing the generator to produce a simulated frequency–shifted signal at the receiver frequency, and feeds it to the receiver input through relay K1. CPU Circuit The CPU PCB (N501–CPU–C) is built around a 16–bit single–chip microcomputer (U10) that has a CPU clocked at 24 MHz by crystal–controlled oscillator X1, and on–chip flash ROM for program software and on–chip RAM providing memory space for data processing of the demodulated signal. An external static RAM (SRAM) chip (U5, 512 kB) is mounted for message and ID storage, and is backed up by large capacity capacitor C6 (1.0 farad) for approx. 10 days in the event of continuous power–off. Another external SRAM (U1, 256 kB) is used to hold text for display on the LCD screen. U3 and U4 are factory–programmed to jointly act as a display controller to perform various display control functions and text scrolling. The input/output interface between the CPU and externally connected devices consists of three external ports: U7 for the RS–232C port, U12 for the *RS–422 port and an opto–isolator for the I/O DATA port. *Input lines to the RS–422 port are insulated from ground by opto–isolators (ISO2, ISO3).

AE-2000 Manual Theory of Operation 8-4 8.7. Operating Principle of NT–2000/DEBEG 2902 ( continued –2 / 2 ) Power Supply Circuit The power supply PCB (N501–PWR–A/B) consists mainly of a switch–mode voltage regulator (U2) and a three–terminal voltage regulator (U1), supplying regulated DC outputs (3.3V, 5V, 12V) from an input voltage ranging 11 to 36 volts, though the nominal voltage is 24 volts at which the performance specifications are fully met. Should the power line polarity be reversed accidentally, diode D1 will cause the fuse F1 (3A) to blow, thereby protecting the input circuit from possible damage. The regulated outputs from the power supply PCB are fed to the CPU PCB, through which the 12V output is also derived to operate the receivers and frequency converter. Another power supply board, termed the FL Inverter PCB (CXA–L0612A–VJL ), is also installed. This PCB is a DC–to–AC inverter unit, generating an AC voltage of approx. 1600V at approx. 60 Hz out of 12V supplied via the CPU PCB to power the fluorescent lamp used to backlight the LCD screen.
