SAFETY NOTICES WARNING: Do not connect the NAV-7 main unit directly to a AC electrical supply, as an electric shock or fire hazard could result. WARNING: Do not connect the NAV-7 system to a DC supply exceeding 31 V or reverse the supply polarity. CAUTION: Do not bypass the built in fuse CAUTION: The NAV-7 system is designed for operation in the temperature range 15 °C to +55 °C. Do not use the system in environments which exceed this range. CAUTION: The NAV-7 unit is not water-proof.
QUICK START NAV-7 is extremely easy to operate: • Apply power at the vessels power switch panel • The NAV-7 will start up after a few seconds delay • Set UTC time and date (automatic when connected to GNSS / GPS) • The NAV-7 will now start to receive and display NAVTEX messages dependant on the transmission schedule of the NAVTEX stations within the vessels current region.
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.
OPERATION NAV-7 CONTROLS The NAV-7 has been designed to be easy to use with an intuitive user interface and softkeys.
Display Icons The NAV-7 displays various icons in the status bar at the top of the display. SAR, warning alarm Unread message indicator The antenna or antenna cable is faulty The 518 kHz receiver is receiving The 490 kHz receiver is receiving The 4209.5 kHz receiver is receiving The external receiver is receiving OPERATION Switch on the NAV-7 by applying power via a circuit breaker or switched fuse.
The NAV-7 is now ready to receive NAVTEX messages. Receiving NAVTEX messages When the NAV-7 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.
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 NAV-7 operates its alarm relay contacts and transmits an NMEA "ALR" sentence to the currently selected alarm port.
Message displays view first lines of each message select another message group move cursor to newest message required message selected message select time frame oldest message for messages Message index display view selected message select next (newer) message Go to next group (see text) go to previous group (see text) select previous (older) message Message summary display scroll display up select next (newer) message select previous (older) message scroll display down view first lines of each mess
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.
• 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.
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% Receiver error rate Received frequency UTC date UTC time Message identifier KA59 Serial number Message category Transmitting Station In the Message Index display only the message identifier is visible.
Colour coding of NAVTEX message headers The NAVTEX message information bars are colour coded for each type of message as defined in the table below.
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.
Setup mode: Receiver options The Setup mode: Receiver options page contains diagnostics to assist with installing and fault finding the NAV-7. The lower part of the display is a monitor area which shows all received NAVTEX characters in real time from the receiver selected as the monitor source, including the phasing character (Ф) and receive character error symbol ( ), regardless of transmitting station and message category filter settings.
Interpreting the diagnostics aids: When a NAVTEX signal is being received, the appropriate receiver frequency icon appears at the top of the display. If the Monitor source is set to this frequency then the received data will appear in the Monitor window. Use the Receive icon, Signal strength bar and Monitor window to help diagnose installation problems and/or as a check that your NAV-7 is working correctly.
Setup parameter Description Software version Display model Serial no Operating Mode These parameters show the software version, hardware model and the individual serial number of the NAV-7.
Setup mode: Serial options The Setup mode: Serial options page contains setup and configuration parameters for the two serial ports on the NAV-7 unit. The lower section of the display provides a monitoring facility for incoming messages on the selected port.
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 NAV-7’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.

INSTALLATION NAV-7 system overview For simplicity, power is shown diagrammatically throughout; fuses, circuit breakers, alternative supplies, etc are omitted.
Trunnion mounting the display The standard bulkhead mounting U-Bracket can be used to mount the NAV-7 above or below a horizontal (or near horizontal) surface. Hole size to fit #10 screw: 3.5mm Drilling drawing (mm) Select hole size to suit method of fixing mountings – clear or tapped holes. Rear view of trunnion bracket assembly Ensure that rubber washers are fitted between the trunnion bracket and the plastic enclosure. Tilt the display to the correct viewing angle. Tighten the two thumbwheels.
Flush mounting the display If the NAV-7 is to be mounted through a flat panel, use the flush mounting kit provided. A cutting template is supplied with the flush mounting kit. This template carries full fitting instructions.
Electrical Connections This manual is concerned only with the installation of the NAV-7 and does not cover the installation of peripheral equipment connected to the NAV-7 such as printers, navigational systems or source of NMEA data in detail. For proper installation and connection of peripheral equipment refer to the installation manuals for these products. The table below shows the connections that must be made to the NAV-7 for it to function correctly.
• 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 the rear of the NAV-7 bracket, or to adjacent metalwork • The screen of the cable should be connected to ship’s earth if possible. The screen of the cable should not be connected to ship’s battery –ve • Safety Warning The NAV-7 has been designed and manufactured to be completely safe when used in accordance with the instructions given in this manual.
Signal line termination RS422 signal lines may need termination resistors at the far end of the serial cable connected to the NAV-7, depending on the length of connecting cable and the rate of data transmission. Both the IBS and the NMEA ports in the NAV-7 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.

Alarm relay The NAV-7 provides a relay connection which can be selected as normally closed or normally open contacts. The alarm relay function is configurable from within the setup pages and can be set (for example) to switch (change state) on receipt of a Search and Rescue message or for a system fault. The red LED on the front panel of the NAV-7 mirrors the function of the alarm relay.
Rear Panel Connections TNC RF connector /8” Spade terminal – ground pin 9-way D-type – NMEA 0183 & printer port USB connector – not currently used 15-way D-type – power and IBS port and alarm relay 1 • The auxiliary alarm contact is capable of switching up to 24 V DC at up to 1 A (inductive load). The contacts are not connected to any internal voltages. • The power supply input is isolated from the case and antenna. It must remain within the range 10.8 – 31.2 V DC (12/24 V DC nominal) at all times.
After connecting the printer, set the 'Printer port' parameter to 'NMEA port' on the Setup mode : Serial options page and ensure that the 'Bridge port' and 'Alarm port' parameters are set to either 'IBS' or 'None'. Set the ‘NMEA port speed’ to 4800. The printer is powered by the mains adaptor supplied and must be configured for correct operation.
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.
Typical installation of active antenna 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.
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 NAV-7 TNC connector. Fitting the TNC connector A TNC connector is supplied as part of the NAV-7 Receiver Kit. • Place the rubber boot, gland nut, washer and rubber seal onto cable.
WARNING Take care not to apply power to the antenna TNC connector from an external supply Switch on the NAV-7 by applying power (12 V DC or 24 V DC) via a circuit breaker or 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 LCD display backlight will come on and the NAV-7 start-up screen will be shown.
