CSB200 Class B AIS R3.0                             3          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. Information contained in this manual is liable to change without notice. Comar Systems Ltd disclaims any liability for consequences arising from omissions or inaccuracies in this manual and any other documentation provided with this product.

CSB200 Class B AIS R3.0                             5         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 CSB200 Class B AIS R3.0                             6         Information Transmitted and Received A Class A unit will transmit its IMO number (if known), MMSI, Call sign and Name, length and beam, ship type, time, course over ground (COG), speed over ground (SOG), heading, navigational status, rate of turn, draught, cargo type, destination and safety related messages via a short message service (SMS) facility. Message lengths are variable with static and voyage related information being transmitted less often.

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.  9 Pin D Cable Colour Signal Name 1 BROWN -NMEA Output (RS422) 2 RED  +RS232 Output 3 ORANGE  +RS232 Input 4  YELLOW  +NMEA  Output (RS422)5 GREEN  Ground 6 BLUE Configurable Switch + 7 VIOLET  Not Used 8 GREY +NMEA Input  (RS422) 9  BLACK  -NMEA Input  (RS422)

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 R3.0                             13         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)
