GENERAL WARNINGS
All marine Automatic Identification System (AIS) units utilise a satellite
based system such as the Global Positioning Satellite (GPS) network or
the Global Navigation Satellite System (GLONASS) network to determine
position. The accuracy of these networks is variable and is affected by
factors such as the antenna positioning, how many satellites are used to
determine a position and how long satellite information has been received
for. It is desirable wherever possible therefore to verify both your vessels
AIS derived position data and other vessels AIS derived position data
with visual or radar based observations.
The proAIS software is intended for use as an installation and
configuration tool. The application is not a navigation tool and should not
be used as such.
LICENSING
IMPORTANT: In most countries the operation of an AIS unit is included
under the vessels marine VHF licence provisions. The vessel on to which
the AIS unit is to be installed must therefore possess a current VHF
radiotelephone licence which lists the AIS system and the vessel Call
Sign and MMSI number. Please contact the relevant authority in your
country for more information. In accordance with a policy of continual
development and product improvement the CSB200 hardware and
software may be upgraded from time to time and future versions of the
CSB200 may therefore not correspond exactly with this manual. When
necessary upgrades to the product will be accompanied by updates or
addenda to this manual. Please take time to read this manual carefully
and to understand its contents fully so that you can install and operate
your AIS system correctly.

INTRODUCTION
Automatic Identification System (AIS)
How AIS Works
The marine Automatic Identification System (AIS) is a location and vessel
information reporting system. It allows vessels equipped with AIS to
automatically and dynamically share and regularly update their position,
speed, course and other information such as vessel identity with similarly
equipped craft. Position is derived from a Global Navigation Satellite
System (GNSS) network and communication between vessels is by Very
High Frequency (VHF) digital transmissions. A sophisticated and
automatic method of time sharing the radio channel is used to ensure that
even where a large number of vessels are in one location, blocking of
individual transmissions is minimised, any degradation of the expected
position reporting interval is indicated to the user and even if the unit
suffers extreme channel overload conditions it will always recover to
normal operation.
AIS Classes
There are two classes of AIS unit fitted to vessels, Class A and Class B.
In addition AIS base stations may be employed by the Coastguard, port
authorities and other authorised bodies. AIS units acting as aids to
navigation (A to Ns) can also be fitted to fixed and floating navigation
markers such as channel markers and buoys.
Class A units are a mandatory fit under 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 and
some leisure craft also fit Class A units.
Class B units are currently not a mandatory fit but authorities in several
parts of the world are considering this. Class B units are designed for
fitting in vessels which do not fall into the mandatory Class A fit category.
The CSB200 is a Class B unit

WARNING: Do not connect the CSB200 unit to a mains (line) AC
electrical supply, as an electric shock or fire hazard could result.
CAUTION: Do not connect the CSB200 unit to a DC supply
exceeding 15.6 V or reverse the supply polarity. Damage to the unit
may result.
CAUTION: The CSB200 unit is designed for operation in the
temperature range -25 °C to +55 °C. Do not install (or use) the
CSB200 unit in environments which exceed this range.
CAUTION: The CSB200 unit should be installed in a location where
it is protected from water and spray.
CSB200 Class B AIS
R3.0 8
Electrical Connections
Connect a 12V DC supply (9.6-15.6V) capable of supplying 2A peak to
the DC power lead .
Positive = RED Negative = BLACK
The case of the unit is not isolated from the negative terminal of the
supply and therefore it is recommended that the unit is not attached
to metal parts of the vessel.
Connect a suitable GPS antenna to the TNC connector (inner of
the two) at the rear of the CSB200. Note that the CSB200 will not
accept GPS NMEA input from another device, it must have its
own internal GPS operating so will require the installation of a
separate GPS antenna.
Connect a suitable VHF antenna to the BNC connector (outer of
the two) at the rear of the CSB200
GPS Antenna
The GPS antenna used must be of the active type (i.e. it should
incorporate an LNA) and must be suitable for marine shipboard
applications (index of protection, ruggedness, means of mounting, etc.).
An antenna should be selected with a gain (in dB) depending on the
length of cable between the antenna and the AIS unit; after subtraction of
cable and connector losses, a minimum total gain of 25 dB should be
available at the CSB200 unit GPS antenna connector.
The GPS antenna to be used for AIS use must be a dedicated antenna,
i.e. not shared with any other GPS receiver.
Installation of the GPS antenna is critical for the performance of the built
in GPS receiver which is used for timing of the transmitted time slots and
for the supply of navigational information should the main navigational
GPS fail. We strongly recommend that:
1. The GPS antenna is mounted in an elevated position and free of
shadow effect from the ship’s superstructure
2. The GPS antenna has a free view through 360 degrees with a
vertical angle of 5 to 90 degrees above the horizon.
3. As the received GPS signal is very sensitive to noise and
interference generated by other onboard transmitters, ensure that
the GPS antenna is placed as far away as possible from radar,
CSB200 Class B AIS
R3.0 9
Inmarsat and Iridium transmitters and ensure the GPS antenna is
free from direct view of the radar and the Inmarsat beam.
4. It is also important that the MF/HF and other VHF transmitter
antennas are kept as far away as possible from the GPS antenna.
It is good practice never to install a GPS antenna within a radius
of 5 meters from these antennas.
VHF antenna
The VHF antenna employed for AIS use:
• Must be either a connected to a dedicated antenna, or shared
with your VHF Radio Transmitter antenna using our AST100
Antenna Splitter.
• Must be suitable for marine shipboard applications (index of
protection, ruggedness, means of mounting, etc.)
• Should be omni-directional and vertically polarised with unity
gain (0 dB) with a bandwidth sufficient to maintain VSWR <1.5
over the frequency range 156 – 163 MHz. As a minimum the
3dB bandwidth must cover the two AIS channels and the DSC
Channel.
• Should be mounted with at least a two metre vertical separation
distance from any other VHF antenna used for speech or DSC
communication.
VHF Antenna Connection
Connecting a badly mismatched VHF antenna, leaving the VHF antenna
port disconnected, or shorting the VHF antenna port will activate the
VSWR alarm, cause the unit to stop sending position reports or cause
damage to the transponder.
Radio Frequency Exposure
To meet the requirements for Radio Frequency Exposure it is necessary
to install the VHF antenna correctly and operate the AIS equipment
according to the instructions.
The VHF antenna must be mounted at a minimum distance (vertical
separation) of 3 metres from the head of any person standing on deck in
order to meet international safety directives on Maximum Permissible
Exposure (MPE) / Specific Absorption Rate (SAR).
CSB200 Class B AIS
R3.0 10
Where no suitable structure exists to achieve a 3 metre vertical
separation then the antenna base must be mounted at least 1 metre
above the head of any person within range, all persons should stay
outside the 3-metre safety radius and if practical a grounded RF shield
should be interposed between people and the antenna.
Failure to adhere to these limits could expose persons within the 3 metre
radius to RF radiation in excess of the MPE / SAR limits.
Data Connection
If an external display unit is to be used to show other AIS units within
range (such as a chart plotter, PC serial terminal or other display device)
connect the user end of the data interface cable to the display device.
Note that the software in the display device must be configured for AIS
operation .
There is a 9-way D-type female connector mounted at the rear of the
CSB200. The standard wire ended data cable assembly provided mates
with this connector.

PROGRAMMING THE CSB200
Before the CSB200 can transmit it requires to be programmed with your
own vessels information. This configuration is done by the vendor of the
CSB200 using data of your vessel.
You will need to provide the vendor of the CSB200 with the following
information:
• Your MMSI number
• Your Vessel name
• Your Radio Callsign
• Your Vessel dimensions
• The planned location of the AIS GPS antenna on your vessel
Instructions for programming the unit are provided to approved vendors
and are not available to end users.
CSB200 Class B AIS

Using the CSB200
Switching on
When the 12VDC supply is switched on the green ON LED will light and
the other six LED’s visible on the front panel of the unit will illuminate
twice for a period of one second on each illumination. The Status, TX Off
and TX LEDs will then go out. The green RX LED will flash when it is
receiving data from other AIS units.
When the internal GPS is locked the yellow LED will go out and the
green Status Led will light; note that this process may take several
minutes depending on the switch-on state of the GPS receiver. The red
TX LED will flash momentarily every time the unit transmits.
NOTE If the unit has not been programmed with an MMSI number the
green RX, yellow Timeout and red Error LED will remain on.
Warning and Fault States
If the unit has not been able to transmit a position report during the last
expected two reporting intervals (i.e. the nominal reporting interval cannot
be maintained for operational reasons such as a Message 23 quiet
period, high channel load conditions, etc) the yellow LED will illuminate.
This is a warning condition only and indicates that your vessels
position is not currently being reported to other vessels. Reception of
other vessel AIS information by the CSB200 is not affected. When the
unit is able to commence reporting the yellow LED goes out.
If a fault occurs the red Error LED will illuminate. This may illuminate
briefly if the power supply is interrupted or if the VHF antenna
characteristics are briefly affected.
CSB200 Class B AIS
R3.0 14
If the Red Error LED illuminates continuously the unit should be assumed
to be faulty and should either be switched off (power removed) or if this is
not practical any other vessel position information derived from the unit
should not be used and it should also be assumed that the unit is not
transmitting valid position information for your vessel.
The unit should be examined by an authorised service agent at the
earliest opportunity.
LED Indicators
ON
This is a green LED which indicates, when lit, that power has been
connected correctly to the transponder.
Status
This is a green LED which indicates, when lit, that the transponder
hardware has been configured, that the operating software is present,
that the CPU has booted up, the application software is running and
everything is correct.
RX
This is a green LED which indicates when flashing that the CSB200 is
receiving data from other AIS transponders and is outputting this data as
VDM NMEA sentences on the output data ports. If the Green LED is on
continuously the unit has not been programmed with its personalised
data. It will still send received data to the output port, but will not transmit.
TX
This is a red LED which flashes momentarily when the CSB200 transmits
its own AIS data.
Timeout
This is a yellow LED which indicates when lit that the transmitter is
prevented from transmitting. Reasons for this include the following:
• The transponder’s internal GPS receiver is not operating or is
not yet ready.
CSB200 Class B AIS
R3.0 15
• The transponder was unable to transmit an AIS message due to
the channel being already occupied, e.g. by transmissions from
other AIS transponders, or the TX Off function is in operation.
Error
This is a red LED which indicates, when lit, one of the following status
conditions is possible:
• Transmitter lockout timer (1 second maximum) has operated
• GPS is unable to gain lock after 30 minutes
• VHF antenna VSWR is out of range
• Power Supply is out of range
• Background noise level is above the threshold level (-77dBm)
Transmit Off Facility.
The Blue LED can be configured by the vendor to operate in 3 modes :
• Switch has no function, default mode as supplied.
• Silent mode facility is provided in the event that you do not wish
to disclose your position to other users or to conserve power
when it is not necessary to transmit your position. The
transmitter can be turned off by connecting a simple ON/OFF
switch between the Blue cable on pin 6 and the Green cable on
pin 5. Closing this switch will cause the Blue-TX off LED and
the Yellow Timeout LED to light, the Green Status LED will
extinguish. Opening the switch will resume transmissions.
Reception of AIS data during this operation will not be affected.
• Send Safety Related Message will send a Type 14 message
with your MMSI number and the words MAYDAY MAYDAY. The
message can be turned on by connecting a momentary push on
button between the Blue cable on pin 6 and the Green cable on
pin 5. Holding the switch down for 3 seconds will activate the
function and cause the blue LED to light, it will stay illuminated
for 1 minute, further pushes of the switch, after the Blue LED
extinguishes, will repeat the message.

Built in Integrity Test
The CSB200 is equipped with Built In Integrity Testing (BIIT). BIIT tests
run continuously or at appropriate intervals simultaneously with the
standard functions of the equipment. The BIIT detects any failure or
malfunction that will significantly reduce integrity or stop operation of the
CSB200 unit.
The tests include:
• AIS TX malfunction (synthesiser not locked and TX time-out not
exceeded)
• Antenna VSWR exceeds limit
• Rx channel 1 malfunction (synthesiser not locked)
• Rx channel 2 malfunction (synthesiser not locked)
