ABOUT SMARTFIND GMDSS NAVTEX
The SMARTFIND GMDSS NAVTEX has been designed to meet the requirements of
IMO (International Maritime Organisation) MSC.148 (77) and IEC technical standard
61097-6 (Ed 2.1).
The SMARTFIND GMDSS NAVTEX has three separate receiver channels, one each
tuned to 490 kHz, 518 kHz and 4209.5 kHz. The SMARTFIND GMDSS NAVTEX will
receive on all three frequencies simultaneously in those parts of the world where
transmissions are available (refer to page 43).
The SMARTFIND GMDSS NAVTEX can be set up to filter out stations and/or
message categories that are not required by the User.
The SMARTFIND GMDSS NAVTEX is capable of being connected to an Integrated
Bridge System (IBS), transferring NAVTEX messages to other navigational aids if
required. Note that the IBS must be compliant with the serial port requirements of
IEC 61097-6 (Ed 2.1).
The SMARTFIND GMDSS NAVTEX will accept UTC time & date information via
either COM port if available. UTC time & date will be used to timestamp received
NAVTEX messages.
Permanent installation of the SMARTFIND GMDSS NAVTEX can be made with either
the bulkhead-mounting bracket or the flush panel mounting kit provided.
The NAVTEX antenna should be mounted where it is elevated clear of metal objects
in a location where it cannot easily be damaged.

INTRODUCTION
NAVTEX is a method of transmitting navigational warnings and weather forecasts
from designated coast radio stations. All English language transmissions are made on
the 518 kHz NAVTEX channel. Each NAVTEX station is allocated several time slots
during the day when it is permitted to transmit, normally at four hourly intervals. The
exceptions to this are gale warnings and search and rescue messages which may be
transmitted at any time.
Reception of 518 kHz NAVTEX transmissions is normally limited to an area of 200 -
300 miles radius around each transmitting station, although considerably greater
ranges are possible at night. Subject to IMO approval, additional local language
transmissions are sent on 490 kHz and on 4209.5 kHz, SMARTFIND GMDSS
NAVTEX supports simultaneous reception of all three NAVTEX channels.
Designed to the latest International specifications, SMARTFIND GMDSS NAVTEX
meets IMO requirements under GMDSS and is designed for simplicity of operation. It
will provide up to date MSI (Marine Safety Information) and weather forecasts and is
suitable for use by all classes of commercial vessels and large pleasure craft. It will
display and store NAVTEX messages without manual intervention within designated
areas of NAVTEX service coverage.
If the vessel is located within the coverage area of several NAVTEX stations
(particularly at night), the SMARTFIND GMDSS NAVTEX may overwhelm you with
information. It can therefore be set up to display only those stations and message
categories you want to receive and which are applicable to the area in which the
vessel is currently sailing.
Normally, routine NAVTEX messages are repeated at four hourly intervals. Provided
that the SMARTFIND GMDSS NAVTEX is left running, repeated messages are not
displayed more than once. Each message is retained for three days (72 hours) after
its last reception before being automatically deleted, unless the message has been
marked as locked.
Full detail of the GMDSS NAVTEX service can be found in the Admiralty List of Radio
Signals Volume 5, Global Maritime Distress and Safety System (GMDSS) published
by the United Kingdom Hydrographic Office.
The IMO and various national coastguards also have informative websites; see the
links page at www.mcmurdomarine.com

OPERATION
Switch on the SMARTFIND GMDSS NAVTEX by applying power via a circuit breaker
or switched fuse.
There will be a few seconds delay whilst the software loads the contents of the
NAVTEX message store during which time the front panel red LED will blink.
The SMARTFIND GMDSS NAVTEX start-up screen will now be shown.
This screen disappears after 30 seconds; it may be removed sooner by pressing any
key.
Page 10
The SMARTFIND GMDSS NAVTEX is now ready to receive NAVTEX messages.
Receiving NAVTEX messages
When the SMARTFIND GMDSS NAVTEX begins to receive a signal, one or more of
the receiver icons at the top of the screen will appear to indicate which of the
receivers is active.
When a complete message has been received, a pop-up appears on the display
indicating that a new message is available and the "unread message" icon flashes.
The message can be read by pressing the Enter key, or the popup can be removed
without reading the message by pressing the Right key. As each new message is
received, the SMARTFIND GMDSS NAVTEX may also generate a single short beep
to attract attention to the new message. This audible alert can be disabled on the
Setup mode: System options page if it is not required.
Any messages that are not read immediately will be marked with the "unread
message" symbol in both the Index and Summary modes. The "unread message"
icon at the top of the display continues to flash until all messages have been read.
Note that while the popup Navtex message box is on display only the Enter or Right
buttons have any effect; all other keys are disabled until the popup box is removed.

Page 11
Alarms
The message category is used to classify the nature of each NAVTEX message. Of
particular note are message types 'D' (search and rescue), 'A' and 'L' (navigational
warnings) and 'E', 'B' and 'C' (meteorological warnings). When a message with any of
these message categories is received the SMARTFIND GMDSS NAVTEX operates
its alarm relay contacts and transmits an NMEA "ALR" sentence to the currently
selected alarm port. The alarm relay continues to operate until the alarm is
acknowledged either by removing the popup or by reception of an appropriate NMEA
"ACK" sentence from another connected device. Search and rescue messages
(category 'D') cannot be read later; the popup box can only be cleared by pressing the
Enter key and reading the message.
Finding and viewing NAVTEX messages
The SMARTFIND GMDSS NAVTEX displays NAVTEX messages in several ways
designed to make finding and viewing particular message categories or an individual
message easy and convenient.

Page 13
Message index display
The Message index display shows the identifiers of messages from a specific
receiver. Unread messages have an “envelope” () mark; locked messages (see Full
message display) have a “key” () mark.
Message identifiers can be expanded to show either the first two lines or the full
message by selecting the desired message and pushing the appropriate softkey.
Messages from another receiver can be displayed using the View softkey, which
cycles through the available sources.
Messages are grouped by time interval. The Show softkey cycles through the set
intervals.
Message summary display
The Message summary display shows the first two lines of each message, selected
by various criteria.
Selection criteria are time, station identity and message type. The Sort by softkey
cycles through these criteria.
Depending on the selection, the “group” is a 4-hour period, a station or a message
type.
The Show softkey controls the total number of messages displayed by suppressing
messages which are older than the selected time frame.
A message can be shown in full by selecting it and pushing the View softkey.
Full message display
Because messages are automatically erased 72 hours after they are received, it is
necessary to take action to retain an important message beyond this time. Displaying
the message and pressing the Lock softkey causes the message to be retained
indefinitely. A locked message is identified by a “key” () mark in the Index display.
A locked message is unlocked by displaying it (in this view) and pressing the Unlock
softkey.
Up to 250 messages can be saved for long term retention; once the limit has been
reached, operating the Lock softkey will not lock any more messages until some are
unlocked again.
Minimising the number of messages displayed
After the SMARTFIND GMDSS NAVTEX has been switched on for a while there will
be a large number of NAVTEX messages stored in memory. These can be quite
overwhelming if the user is looking for particular message categories or an individual
message.
Several design features have been incorporated into the SMARTFIND GMDSS
NAVTEX to make day to day operation easier:
 Separate frequency channel pages
Page 14
 Station filtering
 Message category filtering
 Time-limited display of messages
Separate frequency channel pages
A separate NAVTEX message display is provided for each of the 3 receiver channels.
All 518 kHz messages appear together, all 490 kHz messages appear together and
all 4209.5 kHz messages appear together. Switch between these displays by using
the View softkey.
Station filtering
NAVTEX transmitting stations that are not required can be de-selected by making the
appropriate selections in the Setup screens.
Message category filtering
NAVTEX message categories that are not required can be de-selected by making the
appropriate selections in the Setup screens.
Time-limited display of messages
In order to access recent messages quickly the Show softkey can be used to show
only NAVTEX messages that have been received in the selected time period (last
4 hours, last 12 hours etc)
SETUP MODE
To enter Setup mode, press and hold the ENTER key for 3 seconds.
All of the user-editable setup parameters are stored in non-volatile memory and will
be unchanged after a power cycle, unless otherwise stated in the descriptions of each
individual page.
To exit from Setup mode and return to normal operating mode, press and hold the
ENTER key for 3 seconds until the display returns to normal operating mode, or press
the top softkey to select the next main page.
Note that message pop-ups do not appear while in Setup mode to ensure they do not
interrupt the editing of a configuration field. Always exit from Setup mode when you
have finished configuring the SMARTFIND GMDSS NAVTEX and return to normal
mode before leaving the SMARTFIND GMDSS NAVTEX unattended.

Page 15
NAVTEX message headers
At the beginning of each NAVTEX message there is a message header which
identifies the source and nature of message, time and date of reception, received
frequency and error rate.
For example:
KA59 14:16 19-Jul 518 0%
In the Message Index display only the message identifier is visible.
It is recommended that the user takes time to set up the SMARTFIND GMDSS
NAVTEX to filter out those stations and message categories that are not required. In
this way the display is kept uncluttered; only those messages that are required will be
visible.
Messages are selected for display by the SMARTFIND GMDSS NAVTEX’s software
comparing the Station and Message Category information encoded into the message
identifier (e.g. KA in the diagram above) with the filter settings entered by the user
during setup.

Message filters
To enter setup mode, press and hold the ENTER key. After a few seconds the
Message filters page will be displayed.

Page 17
This page can be used to indicate that messages from specified Transmitting Stations
or of specified Message Categories should NOT be displayed, stored or output as
required.
Each receiver has its own separate set of message filters; pressing the
Select
XXXX kHz RECEIVER softkey cycles round the available receivers. The message
filter settings are all non-volatile and will be unchanged after a power cycle.
By default only message categories ‘A’ to ‘F’, ‘H’, ‘J’ to ‘L’, ‘V’ and ‘Z’ are enabled for
all Transmitting Stations. This is indicated by the check boxes for categories ‘G’, ‘I’,
‘M’ to ‘U’ and ‘W’ to ‘Y’ all being marked to indicate that they are being filtered out.
In order to deselect a Transmitting Station or Message Category, navigate to the
relevant checkbox using the pad (, ,  and  keys) and press ENTER. The
checkbox will then be marked to indicate that the Transmitting Station (or Message
Category, as appropriate) is now deselected and will not appear on the display.
Note that deselecting a Message Category (say ‘I’) in the top row (labelled ‘All’) will
remove Message Category ‘I’ from all Transmitting Stations. To disable message
categories from a specific station identity (e.g. ‘K’), scroll down until the selection
panel for ‘K’ is displayed, then select the appropriate check box. Deselecting the first
message category (labelled ‘*’) will toggle the state of all Message Categories from
the selected Station.
Message categories ‘A’, ‘B’, ‘D’ and ‘L’ cannot be individually controlled. A
Transmitting Station cannot be completely deselected but message types can be
deselected with the exception of types ‘A’, ‘B’, ‘D’ and ‘L’.
There are three sets of message filter options for every Transmitting Station and
Message Category. The ‘STORE’ filter indicates that the selected message shall be
neither displayed nor stored in the non-volatile memory. The ‘NRX’ filter indicates that
the message shall not be sent to either COM 1 or 2 on reception (if output of NRX
sentences to either COM 1 or 2 is enabled). The ‘PRINT’ filter indicates that the
selected message should not be sent to the printer on reception (if printer output is
enabled).
Note that the ENTER key toggles the value of any check box from checked to
unchecked and back again. Similarly, toggling any check box in the ‘All’ row, or in the
column headed ‘*’ will toggle the other entries in the row or column as appropriate.

SYSTEM ALARMS
An alarm event state will always generate a message for sending to an IBS or remote
alarm panel as well as actuating the SMARTFIND GMDSS NAVTEX’s remote alarm
relay contacts.
The front panel LED and the buzzer are programmable – see Setup mode:
System options. Consequently, these indicators may or may not activate to
indicate an alarm. For bridge operation an IMO compliant external alarm should be
fitted – see page 32
The SMARTFIND GMDSS NAVTEX may generate alarms with the following alarm
numbers:
Alarm
number Alarm text
001 NAVTEX: Navigational warning
002 NAVTEX: Meteorological warning
003 NAVTEX: Search and rescue information
004 NAVTEX: Receiver (x) malfunction
005 NAVTEX: Self test error
006 NAVTEX: General failure
051 NAVTEX: Memory full
052 NAVTEX: Antenna error
053 NAVTEX: Antenna overload
RECEIVER MONITORING
The SMARTFIND GMDSS NAVTEX continuously monitors the signals being
received, and generates a “Receiver (x) malfunction” alarm (ID code 004) should any
receiver appear to be operating incorrectly. The “x” in the alarm message is 1 for the
490 KHz receiver; 2 for the 518 kHz receiver and 3 for the 4209.5 kHz receiver.
Serial interfaces
The SMARTFIND GMDSS NAVTEX has an IEC 61162-2 compatible serial interface
which can be used to connect the SMARTFIND GMDSS NAVTEX to other equipment
such as an integrated bridge system or a PC running charting software. The IEC
61162-2 serial interface also allows for the connection of a serial printer. The
integrated bridge system should be connected to the COM port of the SMARTFIND
GMDSS NAVTEX (using the 15-way D-type socket at the rear).
Printer Operation (option)
When the ‘Printer mode’ setting on the Setup mode : Serial options page is
set to ‘On Receipt’, the SMARTFIND GMDSS NAVTEX outputs every message to the
printer as it is received, subject to the control of the message filters. In this mode, the

Page 23
SMARTFIND GMDSS NAVTEX operates in a similar manner to a traditional ‘paper-
based’ NAVTEX receiver.
However, in order to conserve paper, when the ‘Printer mode’ setting on the
Setup mode : Serial options page is set to ‘On Demand’, the SMARTFIND
GMDSS NAVTEX will only print messages when instructed to do so.
To print all messages as they are received:
Set the ‘Printer mode’ setting to ‘On receipt’
Ensure all the ‘PRINT’ checkboxes for all stations and message categories on the
message filters page for each receiver are not checked
To print all stored messages from a specified receiver:
Ensure all the ‘PRINT’ checkboxes for all stations and message categories on the
message filters page for each receiver are not checked
Press the ‘Print Messages’ softkey on each of the Message filters pages to
print out all the messages for the corresponding receiver
To print messages from selected stations and message categories as they are
received:
Set the ‘Printer mode’ setting to ‘On receipt’
Use the message filters to filter out the unwanted stations and message categories
To print individual messages only on demand:
Set the ‘Printer mode’ setting to ‘On demand’
While viewing the full text of a message, press the ‘Print Message’ soft key
Note that this will always print the current message, irrespective of the settings of
the message filters
To print all messages from specified locations or specified message categories
only on demand:
Set the ‘Printer mode’ setting to ‘On demand’
Set the ‘PRINT’ checkboxes on the Message filters page to filter out the
unwanted stations and message categories
Press the ‘Print Messages’ softkey to print out all the messages which are not to be
filtered out.
Note that this will only print out the messages for the current receiver. To print all
the messages for each receiver it is necessary to operate the ‘Print Messages’
softkey on each of the Message filters pages in turn.

Ship’s earth connection
The earth terminal on the rear of the SMARTFIND GMDSS NAVTEX display must be
connected to ship’s ground by the earth cable supplied. The earth connection should
be kept as short as possible.
12V or 24 V DC power connection
A connection must be made to a 12 or 24 V DC supply via a circuit breaker capable of
supplying at least 2 amps. Connection should be to the ship’s radio battery and be in
accordance with GMDSS requirements.
 Connections should be made using the 2 m power cable provided
 Use cable ties to restrain the wiring, and so prevent it becoming weakened
by vibration. The connecting cables should be restrained by securing them to
Safety Warning
To ensure the best possible protection of the NAVTEX from
static electricity or nearby lighting strikes, the pre-fitted green
grounding wire (connected to the safety earth spade) must be
connected to a nearby (hull) electrical grounding point.

screen of the cable should not be connected to ship’s battery –ve
Safety Warning
The SMARTFIND GMDSS NAVTEX has been designed and manufactured
to be completely safe when used in accordance with the instructions
given in this manual. To ensure that the complete installation is safe, it
is essential that a fuse or circuit breaker is installed in the power supply
cable as described in the Installation section of this manual.
Isolation between the power supply connections and any other connection to the
SMARTFIND GMDSS NAVTEX is 1 kV minimum.
The DC power source should comply with IMO guidelines for the class of vessel
concerned. National authorities and classification societies may have their own power
supply requirements; these should also be considered.
Signal cable connections
As shown in the table above, the SMARTFIND GMDSS NAVTEX may be connected
to different types of peripheral units including IBS & INS serial ports and printers.
The signal connections are all connected via a serial RS422 type interface; data rates
are selectable at 4800, 38400 or 115200 baud.
In some cases, particularly in retrofit installations, it may not be possible to connect
the SMARTFIND GMDSS NAVTEX directly to the required source/destination for
serial data, because some equipment does not provide the IEC 61162-2 (NMEA)
sentences required by the SMARTFIND GMDSS NAVTEX unit. In such cases a
protocol converter is required between the sensor and the SMARTFIND GMDSS
NAVTEX. Converters are available from different manufacturers, either as direct
protocol converters or frequently as repeater instruments for the sensor.
IEC 61162-1 alarm message example
The alarm number and text are output as part of a standard ALR sentence format, for
example:
$CRALR,<time>,004,A,A,NAVTEX: Meteorological warning*<checksum>

Signal line termination
RS422 signal lines may need termination resistors at the far end of the serial cable
connected to the SMARTFIND GMDSS NAVTEX, depending on the length of
connecting cable and the rate of data transmission. Both COM 1 & 2 in the
SMARTFIND GMDSS NAVTEX have inbuilt 100Ω termination resistors for both Tx
and Rx.
Whether termination is required depends on many factors, particularly the length of
the signal cable and the environment in which the equipment is operating. The
principle is shown in the sketch:
There is only one talker per twisted pair; there can be several listeners. The intention
is that terminations must be provided by the devices at the ends of the line, regardless
of whether they are listeners or the talker, and that no other device should provide a
termination.
Since the SMARTFIND GMDSS NAVTEX contains internal termination, it MUST be at
the end of the line and NOT in the middle.
It is good practice to use screened cables in all ship cable installations. Take care to
connect the cable screen to ship’s ground at one end only of the cable, as connecting
at both ends may cause ground loops and interference to the signals. The cable
screen should not be connected to any part of the SMARTFIND GMDSS NAVTEX.
Connecting to COM port serial interface
The display connection cable is supplied ready for use, and needs only to be plugged
into the appropriate connector on the SMARTFIND GMDSS
NAVTEX.
Display cable: Six twisted pairs, screened, PVC sheathed.
For lengths to 200 meters, use 0.22 mm2 (7/32); Belden
8106 or equivalent.

The printer is powered by the mains adaptor supplied and must be configured for
correct operation. The standard default settings for the printer should be used, except
for the following:
SW-1 Set for serial interface (not parallel)
SW-2 Set for English (not Japanese)
SW-3 Set for XON/XOFF control (not H/W BUSY)
SW-3 Set for 4800bps (not 75bps)
Refer to the DPU-414 manual for details of how to set these parameters.
The compass safe distance for the printer is 1.0 m.
The printer should be secured to prevent it moving during operation. The use of
adhesive foam pads is recommended.
ANTENNA INSTALLATION
Selecting a suitable antenna
The SMARTFIND GMDSS NAVTEX receives transmissions on three frequencies. 518
kHz transmissions are in International English; 490 kHz and 4209.5 kHz
transmissions may be in a local language.
To receive on all frequencies the SMARTFIND GMDSS NAVTEX must be used with a
wide frequency (400 kHz to 5 MHz) antenna that covers 518 kHz, 490 kHz and
4209.5 kHz.
If you have purchased the SMARTFIND GMDSS NAVTEX receiver without an
antenna then a suitable active NAVTEX antenna should be used. Orolia Ltd
recommends the 905-05 as described in the following section.
If an alternative antenna type is used it must be a low impedance 50 ohm
antenna or an antenna with a 50 ohm matching network. A mismatched or high
impedance whip or wire antenna should not be used as the operational range of
NAVTEX reception may be greatly reduced; it is also important that the antenna is
capable of reception over the frequency range specified above.
Wire or long whip antennas must be fitted with a 50 ohm matching transformer.
Important, disable the SMARTFIND GMDSS NAVTEX antenna power setting – refer
to Setup – Receiver mode for details. If in any doubt a qualified GMDSS installer
should be consulted.

Page 35
Installation of the tri-channel NAVTEX antenna
Metal, rigging or other antennas must not be located in the 'NO GO cone' surrounding
the upper part.
Use the mounting bracket supplied; an alternative mounting kit may be purchased if
the mounting arrangement is unsuitable for your installation.
Attach the clamping brackets to the antenna mounting adapter and use the clamping
arrangement to fix to a suitable vertical tube.
Important
NAVTEX antennas must be mounted clear of obstructions and at least
0.5 metres away from other antennas.
Where practical avoid locating the NAVTEX antenna close to MF / HF
transmitting antennas or VHF / AIS antennas.
Ensure that antennas cannot be snagged by mooring warps or running
rigging or engulfed by green water.
Antennas should always be mounted vertically in an elevated position.

Thread the PL259 connector end of the coax cable through the antenna mounting
adapter and secure the connector to the antenna 1" threaded adapter.
Slide the rubber boot over the PL259 connector; if desired, it may be filled with
silicone grease for a better weatherproof seal.
Screw the antenna down into the antenna mounting adapter.
Ensure that the mounting adapter is connected to ground. If necessary, connect a
grounding wire, 2.5 mm2 minimum, to a suitable ground point.

Installation of the antenna cable
Start routing the antenna cable at the antenna end.
Where the cable passes through bulkheads or decks, waterproof deck glands should
be installed. Securely fasten the cable against vibration using plastic cable tie wraps.
Complete routing of the antenna cable at the SMARTFIND GMDSS NAVTEX TNC
connector.
Fitting the TNC connector
A TNC connector is supplied as part of the SMARTFIND GMDSS NAVTEX Receiver
Kit.
 Place the rubber boot, gland nut, washer and rubber seal onto cable.
Remove the outer insulation for a distance of 8mm.
 Slide the cable braid sleeve over the screen braid, fold the braid back and
trim off extra braid.
 Strip 2.5mm of the inner insulation to
expose the centre conductor.
 Solder the pin onto the centre conductor.
 Assemble the connector and tighten
the gland nut. Push the rubber boot
securely over the gland nut.
Extending the antenna coax cable
If required, the coaxial cable may be extended with 50 ohm coaxial cable and
connectors. The maximum cable length should not exceed 100 m. Ensure that any
cable joints are well secured and waterproofed using self-amalgamating (rubber) tape.
Cable should be RG-58 / RG-67 / RG-213 / RG-214 grade or better; connectors
should be suitable RF types (TNC, BNC, etc).
Testing the tri-channel active antenna installation
By default the SMARTFIND GMDSS NAVTEX provides a regulated 12 V DC (nom)
100 mA output to provide power for an active antenna such as the one supplied as
part of a SMARTFIND GMDSS NAVTEX System.
