1 Introduction 1.1 General overview The NAIS-300 is a Class B Transponder that’s purpose is to transmit the position and other information about your vessel, to other AIS equipped vessels. It is housed in a rugged waterproof enclosure to withstand the rigors of the marine environment. The NAIS-300 uses a sophisticated automatic digital time sharing technology which enables the exchange of static information like; MMSI (Maritime Mobile Service Identifier) Number, Vessel’s Name, Call Sign and Type.
1.2 SimNet/NMEA2000 SimNet is Navico’s proprietary high speed data bus network compatible with NMEA2000. It provides intelligent sharing of data and control information between a wide range of marine electronics and instruments.
2 Installation 2.1 General The NAIS-300 is designed to be mounted on a flat surface somewhere out of sight, but easily accessible. However, to determine the best possible location, you need to consider how and where, you are going to run the cabling from the sides of the unit. The NAIS-300 is very simple to install, however, the performance of the equipment is directly affected by the quality of the installation. Please read these instructions carefully before attempting installation.
2.3 Cabling Once you have secured your NAIS-300 to a flat surface, you will need to connect the power, SimNet/NMEA2000 and RS232 cables supplied with the unit. The RS485 cable and switch are not supplied, but would be fitted in the same manner. Power +12vdc Out +ve NMEA0183-HS (RS485) 0v. Out -ve In +ve In -ve NMEA0183-HS (RS232) Out -ve Gnd.

1 2 3 4 5 6 7 Choose the nipples directly above the parts of the connector you want to wire into and cut off the top section to the required diameter. Pass the power and RS232 cables through the cradle and then through the hole in the respective nipple. Bare the ends of the cables and wire into the correct section of the connector. Once you have wired the two connectors, firmly push them into their mating part in the main unit. Slide the grommet down the cable until it is seated on the main housing.
NMEA2000 (300-L model only) With the supplied cable connected to the NAIS-300, connect the other end into the supplied T-connector, then connect this into the vessels NMEA2000 network. 2.5 NMEA0183-HS (RS232 supplied) This data cable is used to connect the NAIS-300 to a PC or laptop in order to configure it, and for AIS enabled PC chartplotter applications. For further information regarding the wiring of this cable please refer to chapter 3.2 2.
The cable can be routed in the molding to drop down directly underneath, or by breaking out the thin traps, the cable can be routed out of the side of the antenna. Rx Alternatively, the antenna may be fixed on a standard 1” threaded mounting pole (Not supplied). Attach the supplied mounting base to the antenna with the four screws, thread the cable down the center hole and through the pole. Thread the pole into the mounting base, before attaching the pole to the superstructure.
The most important factor in the performance of any AIS transceiver will be the quality and positioning of the antenna. As the range of VHF signals are governed by line of sight, the antenna should be placed as high as possible, while remaining clear of any metallic objects. Long whip antennas are generally recommended for larger boats, although the most popular antennas for marine use is 1m (3ft 3in) long.
The antenna cable should terminate in a standard marine PL259 plug fitting. Connect the antenna plug to the socket on the side of the unit and screw the retaining collar down. Figure 2.3. To avoid possible water damage to the transceiver, it is recommended that all cables are looped to provide a drip path.
Installation
3 Configuration 3.1 General Before the NAIS-300 can become fully functional, it will be necessary to load the following information about your vessel into the unit: • • • • • Vessels Name Call Sign MMSI Number Vessels Dimensions Vessel Type In order to enter this information, you will need to connect your NAIS-300 to your PC or laptop through the supplied RS232 cable. This can be done in the comfort of your living room at home. 3.
For security reasons the MMSI of the vessel cannot be changed once programmed. Do not programme the MMSI unless you are certain you have the correct information. Please check the number entered carefully. If the MMSI programmed is incorrect the AIS transponder will need to be returned to the supplier for factory reset.
4 Operation 4.1 General The NAIS-300 has a limited user interface, consisting of a transmit enable/disable switch, (not supplied), and four indicators on the top of the unit, they are: • • • • PWR [Green] - Power/GPS Lock Status/Silent Mode BIIT [Red] - Built In Integrity Test TX [Yellow] - Transmit RX [Blue] -AIS Message Received 4.
6 flashes - noise threshold exceeded 7 flashes - voltage supply fault The “BIIT” message will remain there until the fault is cleared by the NAIS-300 circuitry, or the unit has been repaired. TX After the initial five seconds the LED will then go out. It will light for one second every time the unit transmits its AIS data. The LED will also light continuously if a transmitter time-out fault occurs. RX After the initial five seconds the LED will flash every time an AIS message is received. 4.
5 Appendix 5.1 Maintenance Periodically check that the cables are secure and that the connectors have not worked their way loose. 5.2 Troubleshooting These simple checks should be carried out before seeking technical assistance and may save time and expense.
