2 SYSTEM DESCRIPTION An overview of the complete TT-3000E mini-C GMDSS System is shown in Figure 1.

Figure 1 TT-3000E mini-C GMDSS System overview

Detailed information concerning the TT-3000E mini-C GMDSS System (with SSAS) can be found in ref. [1], [2] and [3]. This manual only holds detailed information about the TT-3606E Opt. 003 NMEA Adapter

2.1 TT-3606E OPT. 003 NMEA ADAPTER

For interfacing NMEA signals to the TT-3000E mini-C GMDSS System, the TT-3606E Opt. 003 NMEA Adapter is used. It is designed to be located inside a vessel close to the TT-3606E Message Terminal.

It includes one NMEA talker port and one NMEA listener port. The listener port is galvanic isolated from ground (according to IEC 61162-1 & IEC 61162-2). The ports can operate at baud


11/26

rates up to 38400, but the baud rate must be the same on both channels.

Figure 2 TT-3606E Opt. 003 NMEA Adapter

IMPORTANT NOTICE: The GPS data transmitted on the NMEA output (Talker) is meant to be used for date, time and position information for other GMDSS systems without internal GPS. An example of such systems could be VHF and MF/HF radios with DSC. The data is NOT meant to be used for navigational purpose. Although repeated approximately every second, the content of the NMEA sentences are only updated every 30 seconds.

3 SYSTEM INSTALLATION This chapter provides specific information enabling you to install the TT-3606E Opt. 003 NMEA Adapter on a TT-3000E mini-C GMDSS System with a minimal effort. The default, or factory configuration, is described together with procedures for altering this configuration. The TT-3606E Opt. 003 NMEA Adapter connects to the TT-3000E mini-C GMDSS system using a standard RS232 cable with DSUB9 connectors (male/female) connected to COM2 on the TT-3606E Message Terminal.


13/26

3.1 INSTALLATION OF THE NMEA ADAPTER

The TT-3606E Opt. 003 NMEA Adapter is designed to facilitate a simple and robust interconnection to various external NMEA based system components.

14/26

3.1.1 MOUNTING OF THE NMEA ADAPTER

The TT-3606E OPT. 003 NMEA Adapter is designed to be mounted on a flat surface anywhere inside a vessel and to be located within a few meters from the TT-3606E Message Terminal. In case the power supply originates from the +9VDC output of the TT-3616C Interconnection Box the distance from this box should also be kept within a few meters. In order to ease the installation, please observe the minimum clearing area as given in Figure 5.

The unit must be fastened by the used of 4 screws, one in each corner of the chassis as indicated by Figure 6. The accessories for TT-3606E OPT. 003 NMEA Adapter include 2 different types of screws for the purpose, M5x12 and 5.5x25.

Figure 6 Drill template. All measures in mm.

The best grounding is made by fixing the chassis directly on to the ships structure (provided it’s made of metal). If proper grounding can not be made this way, then connect the pre-mounted grounding wire to the ships structure. Find an appropriate location as close as possible to the TT-3606E OPT. 003 NMEA Adapter and shorten the grounding wire accordingly. Terminate the grounding wire with the yellow ring terminal found in the accessory kit. The correct (pre-mounted) position of the grounding wire can be seen on Figure 4. Please note the use of a washer underneath the yellow ring terminal. The grounding wire delivered with the TT-3606E OPT. 003 NMEA Adapter has a length of 1 meter and a wire cross section of 4mm2. Avoid extending the length of the grounding

wire, as the protective effect will be severely degraded in such a case.


17/26

3.1.2 HANDLING OF WIRE TERMINALS

To help inserting wires into the terminals, a special tool is delivered as part of the accessory kit. It is used as shown in Figure 7 (the picture shows another unit, but the principle remains the same).

Please be careful not to apply to much pressure, as this might

damage the top of the terminal housing. In case the special tool is lost, a small screwdriver can be used as well.

3.1.3 CONNECTING POWER TO THE NMEA ADAPTER

The TT-3606E OPT. 003 NMEA Adapter is designed to operate on DC in the range 8 - 32 V. As “DC-“ is connected directly to GND (Chassis), the supply to the TT-3606E Opt. 003 NMEA Adapter must be taken directly from the +9VDC output on the TT-3616C Interconnection Box. This ensures correct operation even during switch over to battery operation during an AC failure situation. When connecting the power supply cable to TT-3606E OPT. 003 NMEA Adapter, make sure the cable screen is properly terminated at the cable relief bracket as shown in Figure 8. Connect the positive supply wire to the terminal denoted “DC+” and the negative supply wire to the terminal denoted “DC-“. Do not connect the cable screen at the other end of the cable.

Figure 7 Wire tool

Figure 8 Power cable connections.

When power is switched on, the green LED denoted “POWER OK” should be turned on. The current drawn will range from around 30mA when used as a listener only. When the talker is active, the current drawn can be up to 130mA when fully loaded.


19/26

3.1.4 WIRING NMEA SIGNALS

The TT-3606E Opt. 003 NMEA Adapter has one talker port (labelled “NMEA OUT”) and one listener port (labelled “NMEA IN”). The labelling is shown in Figure 9.

Figure 9 Talker and listener labelling

To ease wiring there are 2 terminals for each signal. They are internally connected to each other as can be seen in Figure 10. In case the listener is placed at the end of the cable and the baud rate is higher than 4800 baud, it is recommended to terminate the cable. Provided the impedance of the cable is around 120Ω, an internal 120Ω resistor can be enabled by connecting jumper W1.


20/26

Figure 10 I/O Schematic

The recommended cabling principles are shown in Figure 11.

Figure 11 Wiring of NMEA Talker & Listener

As can be seen from Figure 11 it is important to avoid getting the cable shield in contact with the chassis when connecting wires to the listener input.


21/26

When connecting equipments with only A and B terminals (IEC 61162-1 equipment), simply leave the C terminal unconnected. IMPORTANT NOTICE: The TT-3606E Opt. 003 NMEA Adapter Listener (NMEA IN) is not compatible with old unbalanced NMEA 0183 talkers characterised by VA ≥ VB at all times (VA = voltage at terminal A etc.). Talkers compliant to IEC 61162-1 and/or IEC 61162-2 will interface without problems.


22/26

4 TEST OF THE SYSTEM This section provides information on how to perform system checks as well as help for troubleshooting. Concerning the initial start up and use of the TT-3606E Message Terminal, please refer to the user manual, ref. [1]. Remember to enable the NMEA functionality (TT-3606E menu path: <Application><System><Options><Serial ports>).

4.1 VERIFICATION OF CORRECT POWER SUPPLY

The TT-3606E Opt. 003 NMEA Adapter has one light emitting diode (LED) to provide basic installation and troubleshooting help. The location of the LED is shown in Figure 12.

Figure 12 TT-3606E OPT. 003 NMEA Adapter LED location.

When applying power to the TT-3606E OPT. 003 NMEA Adapter, the “DC in” LED will light up. In case the LED does not light up, then:

1) Check the wiring. 2) Check the power supply source.


23/26

4.2 VERIFICATION OF NMEA IN DATA

As the NMEA IN data are used solely to form an additional position data string in the SSAS message, simply send a SSAS Test Message to verify the correctness of data. Refer to the TT-3000E SSAS Installation Manual for further information, ref. [3]. Be aware, that the additional position data string in the SSAS Message is only updated every 30 seconds.

4.3 VERIFICATION OF NMEA OUT DATA

Verification of correct NMEA output data should be done by checking that each listener device receives the appropriate information according to their needs. Be aware, that although the NMEA sentences are repeated approximately every second, the content is only updated every 30 second.


24/26

5 MAINTENANCE GUIDELINES When properly installed the TT-3606E Opt. 003 NMEA Adapter needs no maintenance.
