General Warnings

All marine Automatic I entification System (AIS) units utilise a satellite base system such as the Global Positioning Satellite

(GPS) network or the Global Navigation Satellite System (GLONASS) network to etermine position.

The accuracy of these networks is variable an is affecte by factors such as the antenna positioning, how many satellites are

use to etermine a position an how long satellite information has been receive for.

It is esirable wherever possible therefore to verify both your vessels AIS erive position ata an other vessels AIS erive

position ata with visual or ra ar base observations.

The compass safe istance of this unit is 0.5m or greater for 0.3° eviation.

In accor ance with a policy of continual evelopment an pro uct improvement the TRANSAS AIS CLASS B har ware an

software may be upgra e from time to time an future versions of the TRANSAS AIS CLASS B may therefore not correspon

exactly with this manual.

When necessary upgra es to the pro uct will be accompanie by up ates or a en a to this manual.

Please take time to rea this manual carefully an to un erstan its contents fully so that you can install an operate your AIS

system correctly.

Information containe in this manual is liable to change without notice.

This equipment generates, uses an can ra iate ra io frequency energy an , if not installe an use in accor ance with the

instructions, may cause harmful interference to ra io communications. However, there is no guarantee that interference will not

occur in a particular installation. If this equipment oes cause harmful interference to ra io or television reception, which can be

etermine by turning the equipment off an on, the user is encourage to try to correct the interference by one or more of the

following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment an receiver.

• Connect the equipment into an outlet on a circuit ifferent from that to which the receiver is connecte .

• Consult the ealer or an experience ra io/TV technician for help.

The TRANSAS AIS CLASS B- oes not contain any user serviceable parts. Repairs shoul only be ma e by an authorize

TRANSAS service agent. Unauthorise repairs or mo ifications coul result in permanent amage to the equipment an voi

your warranty an you’re authority to operate this equipment un er Part 15 regulations.

RF Emissions Notice

Caution The TRANSAS AIS CLASS B Class B AIS transponder generates and radiates radio frequency

electromagnetic energy. This equipment must be installed and operated according to the instructions contained in this

handbook. Failure to do so can result in personal injury and / or product malfunction.

Caution Never operate the transponder unless it is connected to a VHF antenna.

To maximise performance an minimise human exposure to ra io frequency electromagnetic energy you must make sure that

the antenna is mounte at least 1.5 meters away from the transpon er an is connecte to the transpon er before power is

applie .

The system has a Maximum Permissible Exposure (MPE) ra ius of 1.5m. This has been etermine assuming the maximum

power of the transpon er an using antennas with a maximum gain of 3 Bi.

• The antenna shoul be mounte 3.5m above the eck in or er to meet RF exposure requirements.

• Higher gain antennas will require a greater MPE ra ius.

• Do not operate the unit when anyone is within the MPE ra ius of the antenna (unless they are shiel e from the

antenna fiel by a groun e metallic barrier).

• The antenna shoul not be collocate of operate in conjunction with any other transmitting antenna.

This evice has been esigne to operate with stan ar marine VHF antennas having a maximum gain of 3 Bi. Antennas not

inclu e in this list or having a gain greater than 3 Bi are strictly prohibite for use with this evice. The require antenna

impe ance is 50 ohms

Licensing and Maritime Mobile Service Identity (MMSI)

IMPORTANT: In most countries the operation of an AIS unit is inclu e un er the vessel's marine VHF licence provisions. The

vessel on to which the AIS unit is to installe must therefore possess a current VHF ra iotelephone licence which lists the AIS

system an the vessel Call Sign an MMSI number.

An MMSI number is required in order for the TRANSAS AIS CLASS B transponder to operate.

Please contact the relevant authority in your country for more information.

Intro uction

How AIS Works

The marine Automatic I entification System (AIS) is a location an vessel information reporting system. It allows vessels

equippe with AIS to automatically an ynamically share an regularly up ate their position, spee , course an other

information such as vessel i entity with similarly equippe craft. Position is erive from a Global Navigation Satellite System

(GNSS) network an communication between vessels is by Very High Frequency (VHF) igital transmissions. A sophisticate

an automatic metho of time sharing the ra io channel is use to ensure that even where a large number of vessels are in one

location blocking of in ivi ual transmissions is minimise , any egra ation of the expecte position reporting interval is

in icate to the user an even if the unit suffers extreme channel overloa con itions it will always recover to normal operation.

AIS Classes

There are two classes of AIS unit fitte to vessels, Class A an Class B. In a ition AIS base stations may be employe by the

Coastguar , port authorities an other authorise bo ies. AIS units acting as ai s to navigation (A to Ns) can also be fitte to

fixe an floating navigation markers such as channel markers an buoys.

Class A units are a man atory fit un er the safety of life at sea (SOLAS) convention to vessels above 300 gross tons or which

carry more than 11 passengers in International waters. Many other commercial vessels an some leisure craft also fit Class A

units.

Class B units are currently not a man atory fit but authorities in several parts of the worl are consi ering this. Class B units are

esigne for fitting in vessels which o not fall into the man atory Class A fit category.

The TRANSAS AIS CLASS B - is a Class B unit

Position Information Source

As note above the marine AIS system uses position information erive from networks such as the Global Positioning Satellite

(GPS) or the Global Navigation Satellite System (GLONASS) in or er to etermine the location of the AIS unit an thus the

vessel to which it is fitte .

The TRANSAS AIS CLASS B- utilises the GPS satellite network.

install (or use) the TRANSAS AIS CLASS B unit in environments which excee this range.

CAUTION Do not install the TRANSAS AIS CLASS B unit in an environment where it can be subject to excessive

exposure to water.

Electrical connections

Warning Only the RF, ata an power cables provi e with the TRANSAS AIS CLASS B unit shoul be use to connect

antennas, power an isplay evices so as to maintain the integrity of the enclosure.

Please see the rawings section of this manual for etails of the power, ata an RF cables supplie .

Remove the top of the transpon er unit (eight screws) as shown.

Using the two co-axial lea s supplie connect the own-lea from a VHF antenna to the VHF antenna port an connect the

own-lea of a GPS antenna to the GPS antenna port. Please see Appen ix A for recommen ations on antennas an antenna

installation.

If an external isplay unit (chart plotter, PC etc)

is to be use connect the supplie power an

ata interface cable to the Power / NMEA port.

If an external isplay unit is not to be use

connect the supplie power only interface cable

to the Power / NMEA port.

Locate the RF, power an /or ata cables into

the rubber grommets pushing them firmly to the

base of each slit. Each cable is pushe into the

grommet slit which lies irectly in front of the

connector the cable is connecte to.

Replace the top of the transpon er unit taking

care to seat the cable grommets an the li

seal correctly. Do not over-tighten the fixing

screws.

If an external isplay unit is to be use (such as

a chart plotter, PC serial terminal or other

isplay evice) connect the user en of the

ata interface cable to the isplay evice. Note

that the software in the isplay evice must be

configure for AIS operation AND to accept

stan ar Class B operation NMEA sentences.

This external isplay unit software is not part of

the TRANSAS AIS CLASS B transpon er

package.

Connect a 12V DC supply (9.6-15.6V) capable

of supplying 2A peak to the DC power lea

(brown/re = positive, black/blue=negative).

The case of the unit is not isolated from the negative terminal of the supply and therefore it is recommended that the
