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. Also dynamic

data like; Position, Course, Distance and more, from ship

to ship, and from ship to shore based traffic stations.

When connected to a compatible chart plotter, it will

provide a representation of the position and movements

of all AIS equipped vessels within VHF range

The advantages of the NAIS-300 are:

Increased awareness of the current shipping

situation within your VHF range through the

exchange of data between vessels.

Improving traffic management in busy shipping

lanes through exchanging information between

vessels and shore based traffic stations.

Reporting information automatically in shipping

areas where it is mandatory.

As with all electronic navigational equipment, it is

only an aid to navigation and should not be used as

a substitute for good seamanship.

Remember - Maritime law requires that you keep a

good lookout at all times.

6 Introduction

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.

Installation 7

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. If in any doubt,

consult a qualied marine electronics engineer.

2.2 Mounting

The transceiver requires a at surface with a minimum

area of at least 210mm x 130mm (8.3in x 5.1in) for

mounting, with an overall area of 210mm x 250mm (8.6in

x 9.8in) to allow for cables.

The surface should be rigid and sturdy enough to be able

to support the weight of the unit, taking into account the

shock loads likely to be encountered when the vessel is

under way in heavy seas.

Hold the unit against the surface where it is to be

mounted, and mark the position of the four holes

with a pencil.

Drill a 3.7mm (.145in) hole on each corner mark.

Align the holes on the NAIS-300 with those you

have just drilled, and fasten with the 4 - No.8 x 3/4

self tapping screws supplied.

8 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.

With reference to the connector wiring, Figure 2.1 and the

assembly diagram, Figure. 2.2, wire your unit as follows:

Installation 9

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, rmly

push them into their mating part in the main unit.

Slide the grommet down the cable until it is seated

on the main housing. Make sure that there is a little

excess cable beneath it, ensuring that the cable is

not pulled tight.

Place the clamp over the grommet and screw down

with the two screws supplied.

Make a small loop from the cables and cable tie

them down to the tongue of the clamp.

2.4 SimNet/NMEA2000 cable (supplied)

The NAIS-300 is connected to the SimNet/NMEA2000

databus using the cable supplied. Pull the splash cover off

of the SimNet/NMEA2000 socket, ensure the connector on

the end of the cable is in the correct orientation and press

firmly into the socket.

SimNet (300-N model only)

With the supplied cable connected to the NAIS-300,

connect the other end into the vessels SimNet network.

10 Installation

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 congure it, and for AIS enabled PC

chartplotter applications. For further information regarding

the wiring of this cable please refer to chapter 3.2

2.6 NMEA0183-HS (RS485 not supplied)

This data cable is used for connectivity to AIS enabled

chart plotters and other marine equipment with an

NMEA0183-HS interface. For wiring information, refer to

Figure 2.1.

(NMEA0183-HS is specied at 38.4kbaud and is not

compatible with conventional NMEA0183, which operates

at the lower speed of 4800baud)

2.7 Transmit disable switch (not supplied)

Any momentary action, push to make switch can be used.

Take a wire from each terminal of the switch and wire

them into the connector. Refer to figure 2.1. Because

there is negligible current drawn through this cable, any

suitable two core cable will do, providing it forms a good

seal once inserted in the grommet. Refer to section 4.3.

2.8 GPS antenna

The antenna, ideally needs to be mounted as low

as possible with a clear view of the sky to minimise

errors due to movement over and above the transitory

movement of the vessel.

The GPS antenna is capable of being flush mounted on

a suitable flat area of the cabin roof or deck area. In

this configuration, fit the supplied rubber gasket under

the antenna and use the four threaded studs, nuts and

washers to fix the antenna down.
