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.

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.
