NOTE: When a type–D message (SAR, piracy and armed robbery information) is
received on either the first or second receiver, 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.
④ 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 (⑩) is received.
NOTE: Whether to display or output the message to external
devices depends on the character error rate
(CER, ⑫)
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.
⑤ 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.

device via the RS–422 port.
⑩ 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.

⑪ Indication of Message Storage Status
This indication shows whether or not the displayed NAVTEX message has been
stored in the internal non–volatile memory.
･ *1STORED: The message has been stored.
When message reception has been completed with a character error rate (CER,⑫)
of 33% or less, the received NAVTEX message together with its ID will be displayed
and 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 with a lower CER.
When the CER exceeds 33%, the message and its ID will not be displayed and will
not be 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.
⑫ 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%, the message 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
⑪ for more information on CER.
⑬ 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

3.7. Stopping Audible and Visual Alarm
Your equipment will warn you audibly and visually upon reception of a vital NAVTEX
message (type–D message), such as SAR information, piracy, or armed robbery warning.
An example type–D alarm message is given below, showing the visual alarm (called the
alarm tag) attached to the message ID. The ID and text are also displayed in red to
indicate that the message below is a type–D alarm message, distinguishable from other
alarm messages (type–A: navigational, type–B: weather, or type–L: other alarm).
Figure 3-8 Visual Alarm Indication for Type–D Message – Example
To silence the audible alarm, simply press .
If another D type message was received before the
current one, its audible alarm will also be stopped.
Pressing the key again will turn off the visual alarm indication (iALARM!ii, alarm
tag), resetting the alarm.
A type–D message will remain fixed and will not automatically scroll until it is
acknowledged or until another D message is received on either receiver.
NOTE: Each alarm can be acknowledged and reset individually with the appropriate
software command via the RS–422 port. See paragraph 7.4.5 for details.
If additional alarm messages are left
unread in memory, that condition will be
indicated as in the example above.
Pressing again will recall the next
unread alarm message onto the screen.
Figure 3-9 Visual Alarm Indication for Type–A Message – Example
The equipment can also be
set to alert you to a
navigational warning (type–A
message), a weather warning
(type–B message) or other
warning (type–L message) via
the menu system described
in paragraph 4.14.

3.8. Protecting Messages for Permanent Storage
3.8.1. 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

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.

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 the
Main 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.

User-Level Troubleshooting
5.12. External Control Problem
The following description of the symptom assumes that your NAVTEX receiver was
properly working for some time after initial installation time.
Symptom Suggested Solution
Alarm acknowledgement cannot be
controlled remotely from IBS/INS
terminals despite correct
connections to the INS port (RS–422
connector).
1. Check to be sure that the RS–422 (INS)
port is enabled (set to ON). See
paragraphs 4.12.1 through 4.12.4 for
details.
2. Check to be sure that the communications
protocol of your application matches that
of the RS–422 (INS) port. See paragraph
4.12.2.2 for details.
3. Check the bit format and baud rate of
your application match those of the RS–
422 port parameters. See paragraph
4.12.4 for details.
4. Suspect that some of the internal
connections to/ from the connectors have
become loosened or broken. Ask your
dealer/qualified engineer to check for
faulty wiring harness terminations.
5. Run the self–diagnostic tests as per
paragraph 4.13, and check the results of
the RAM and ROM tests.
If the indication of either result is
“FAILED,” suspect that the Main PCB has
become defective. Ask your dealer/
qualified engineer to check the PCB and
related wiring harnesses first and to
replace it if necessary.

6. User–Level Maintenance Instructions
To ensure long–term trouble–free operation, the user should regularly follow the
maintenance instructions described in this section.
6.1. Maintenance on the Equipment Cabinet
Keep the equipment, away from sea splashes, direct sunlight and other heat–generating
sources, and make sure that air around the cabinet is circulating freely. If the
equipment is not going to be used for extended periods of time, dismount the cabinet
from the vessel and place them in dry storage. Be sure to switch the equipment off
before removing electrical connections from the rear panel.
< WARNINGS >
1. BE SURE TO TURN IF OFF AND UNPLUG THE POWER CABLE BEFORE OPENING
THE CABINET FOR INSPECTION.
2. CHEMICAL SOLVENTS, SUCH AS PAINT THINNERS AND BENZENES, MUST NOT
BE USED TO CLEAN THE CABINET OR SCREEN FILTER, OR PERMANENT
DAMAGE TO THOSE PARTS WILL RESULT.
3. ALL MESSAGES STORED IN MEMORY, INCLUDING PROTECTED ONES, WILL BE
ERASED IF THE UNIT IS TO BE TURNED OFF CONTINUOUSLY IN EXCESS OF 10
DAYS. IMPORTANT MESSAGES SHOULD BE PRINTED OUT OR SAVED INTO
APPROPRIATE STORAGE MEDIA VIA A PC CONNECTED TO THE RS–422 PORT.
To clean the cabinet surface, a neutral type household detergent intended for office
equipment is recommended. Cleaning the acrylic filter on the LCD screen should be a
maintenance routine to avoid using a high brightness level. To clean the screen filter,
use a piece of slightly wet cloth. If stains persist, the cloth may be moistened with a
neutral type household detergent.
To prolong LCD Screen’s Service Life
To increase the service life of the LCD screen (life of the white LED lamps for
backlighting), it is recommended that the screen sleep mode be activated as per the
instructions in paragraph 4.5.
6.2. Maintenance on Electrical Connections
The high humidity marine environment can cause electrical contacts in the rear panel
connectors to corrode over time. Vibrations and shocks normally encountered on the
vessel in motion can cause the electrical contacts to become loosened. Corroded or loose
contacts will become responsible for erratic, intermittent operation or performance
degradation. To avoid such possible problems, conduct the following maintenance
operations at least once a year:
● Unplug all the cables from the rear panel, and check to be sure that contact surfaces,
including the pins in the rear–panel mounted receptacles are free from corrosion.
● Check the connections at the ship’s DC power source for freedom from any sort of
corrosion.
● Correct any problem using a high quality contact–cleaning agent (contact
rejuvenator). < WARNINGS >
1. BE SURE TO TURN THE EQUIPMENT OFF BEFORE REMOVING / INSTALLING THE
CONNECTIONS FROM / TO THE REAR PANEL CONNECTORS.
2. SANDPAPER WILL DAMAGE THE CONTACT SURFACE AND MUST NOT BE USED.

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 2.3 kg in total. The dimensions
necessary for installation are given in Figure 7–1. 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: 0.45m (standard), 0.30m (steering)
・ Cabinet with Bracket: 0.60m (standard), 0.35m (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.

7.2. Antenna Installation
The dimensions of the active antenna unit (ANT–2000M) is given in Figure 7–2.. The
equipment does not support the use of a wire antenna. The receiver input is low
impedance and is not suitable for wire antenna connection.
7.2.1. Installation Site Requirements
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.
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
WITH THE SECOND OPERATING AT 4209.5 KHZ) WITH THE EQUIPMENT
SWITCHED ON. DO NOT SHORT THE CENTER CONDUCTOR TO GROUND OR
DAMAGE TO THE INTERNAL CIRCUITRY CAN RESULT.
< CAUTION >
Water intrusion into the coax cable will electrically damage the cable, making
it impossible to use it as a feeder any longer. A serious drop in sensitivity will
result.

7.4.2. Controlling Receiver Operation via INS (RS–422) Port
To externally control receiver operation via the RS–422 port, the equipment supports
the following command sentence (IEC 61162–1 format). Up to 10 commands will be
stacked and executed sequentially. Using the transmitter mask and message mask, the
user can select the station IDs and message types for message storage in the
non–volatile memory, for message output to the RS–422 port (INS port) or to the
RS–232C port (printer port). Message types A, B, D and L, however, cannot be rejected.
Previous selection/rejection settings manually entered via the keypad will be changed

AE–1800 Instruction Manual l
Theory of Operation
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 due to 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.

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–1800 NAVTEX Receiver
The AE–1800 receiver has two built–in receivers on the same receiver board, with the
first receiver devoted to receiving 518 kHz broadcast at all times and the second
receiver receiving either 490 kHz or 4209.5 kHz signal as selected by the user through
the menu system. 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 for each receiver.
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 IBS/INS terminal connected
to the RS–422 port on the rear panel. When a type–D message is received on the second
receiver alone, the display automatically switches to the second receiver page, showing
its message in red while sounding the alarm in the same manner as on the first receiver.
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. An optional printer can also be plugged in to
print the current message in real time or those recalled from the non–volatile memory.

8.7. Operating Principle of AE–1800
Figure 8–1 shows interconnections between the printed circuit boards (PCBs)
comprising the AE–1800 system and interface connections from the PCBs to data
input/output ports and peripheral devices. A functional block diagram of the receiver
PCB is given in Figure 8–2..
To follow the circuit description below, see also the block diagram and schematics of the
receiver PCB and Main 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 local
oscillator that is switched into operation when the second receiver frequency is changed
to 4209.5 kHz. All receivers are mounted on the receiver PCB (S602–RCV–A).
Both 518 and 490 kHz signals picked up at the *active antenna’s preamplifier pass
through a bandpass filter (L4, L19) and are then amplified by a common RF amplifier
(Q4).
*
The active antenna contains three passband filters, independently tuned to the three frequencies,
each followed by a single stage preamplifier. The 490 kHz filter and 4209.5 kHz filter are switched by a
relay when the second receiver frequency is changed.
The amplified signals are then separately filtered by crystal filters (F1 for 518 kHz, F2
for 490 kHz) to avoid cross–channel interference and reject interference adjacent to
each frequency.
A 4209.5 kHz signal goes through its devoted bandpass filter (L3, L6). After being
amplified by RF amplifier Q5, it is fed to a diode mixer (D3, D4), which converts the
4209.5 kHz signal into a 490 kHz signal through heterodyne action using a local
oscillator output (3719.5 kHz) derived from crystal oscillator U3 (29.756 MHz) through
a divide–by–8 frequency divider (embedded in U3’s package). The 490 kHz output is
then fed to the 490 kHz crystal filter F2 through a switch (U1, Q6).
After passing through the appropriate crystal filter, each signal is again amplified (by
Q10 for 518 kHz, Q11 for 490 kHz) and then fed to an FM detector ( U9 for 518 kHz, U10
for 490 kHz), which demodulates a frequency–shifted (carrier±85 Hz) RF NAVTEX
signal into a stream of baseband pulses at 100 baud using quadrature detection
technique. The detected output is then fed to the CPU via a lowpass filter and
comparator chain (U11 for 518 kHz, U12 for 490 kHz) and an opto–isolator (K7 for 518
kHz, K8 for 490 kHz).
To test whether each receiver is functioning properly, two NAVTEX signal generators
are provided on the same PCB, each consisting of crystal–controlled oscillator (U5 for
first receiver, U4 for second receiver) and common divide–by–16 frequency divider U2.
When the self–diagnostic test function is activated via the menu, each generated signal
will be mixed by diode mixer D5 with the 3719.5 kHz output from local oscillator U3,
producing test signals at 518 kHz and 490 kHz. They will then be fed to their respective
amplifiers in the same manner as live NAVTEX signals are processed.

8.7. Operating Principle of AE–1800 (
continued –2 / 2
)
CPU Circuit
The Main PCB (M613–MAIN–X) carries a CPU circuit and a power supply circuit. The
CPU is a 16–bit single–chip microcomputer (U10) 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 signals.
An external static RAM (SRAM) chip (U5, 512 kB) is mounted for the storage of
messages and IDs, and is backed up by large capacity capacitor C6 (1.0 farad) for
approx. 10 days in the event the unit is placed in a continuous power–off condition. A
portion of the memory capacity is allocated as a video RAM (VRAM) to hold text for
display on the LCD screen.
U3 is factory–programmed to 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: U4 for the RS–232C and
I/O DATA ports, U12 for the RS–422 port.
Power Supply Circuit
The power supply circuit consists mainly of a switch–mode voltage regulator (U55), a
power transformer (T51), a DC–to–DC converter (U52) (or U57 3–terminal voltage
regulator) and a 3–terminal voltage regulator (U56), producing various regulated
outputs (3.3V for IC chips, ±12V for RS–232C port, +12V for the receiver PCB, +5V for
RS–422 port, etc.) required for operation of the entire Main PCB circuitry.
The voltages (+8V and +5V) required for receiver operation are derived from the +12V
output through 3–terminal regulators (U7 and U8) on the receiver board.
Should the power line polarity be reversed accidentally, diode D51 will cause the fuse F1
(3A) to blow, thereby protecting the input circuit from possible damage. A varistor
(VA51) is placed across the DC input line to protect the power supply circuit from
possible damage in the event voltage transients on the ship’s power line voltage exceed
40V.

(24.00 MHz) to compute message aging.
・Storage without Power: Protected messages are stored for at least 10 days after
power is removed continuously.
(18) Message Protection: Up to 50 messages on each receiver screen can be
protected against automatic erasure, and are saved in a
separate area of the non–volatile message memory.
Protection of a user–selected message can be cancelled
to allow automatic erasure after a 60–hour time
passage.
Protected messages are indicated with *3tag
iPROTECTEDi attached to the message ID.
