1GENERAL
1.1 Features
The AIS Base Station (AIS BS) is a shore based Automatic Identification System who consists of a
TR-2600 Transponder in a 19” rack, a AC/DC power supply and an interconnection board.
The AIS BS is capable of exchanging navigation and Base Station data to/from ships and other
costal stations through VHF Data Link (VDL). To be able to operate, the TR-2600 Transponder
needs commands from a Base Station Controller (BSC), which may be connected to a Management
System. The AIS BS is the most basic AIS-related entity of any AIS Shore Infrastructure.
1.1.1 The main features are:
Autonomous transmission of Base Station Reports, configured by BSC
Data Link Management, configured by BSC
Channel Management, configured by BSC
Safety of navigation by automatically exchanging navigational data between ships and coast
stations. Data received from ships:
-Static data:
-MMSI ( Maritime Mobile Service Identity).
-IMO number (where available).
-Call sign and name.
-Length and beam.
-Type of ship.
-Location of position-fixing antenna on the ship.
-Dynamic data
-Ships position with accuracy indication and integrity status.
-UTC.
-Course over ground (COG).
-Speed over ground (SOG).
-Heading.
-Navigation status (manual input).
-Rate of turn (where available).
-Voyage related data
-Ships draught
-Hazardous cargo(type)
-Destination and ETA (at masters discretion).
Short safety related messages and other short messages .
LCD panel satisfying the IMO minimum requirements.
Interfaces for radar, ECDIS, PC, LAN for future networking expansion.
GPS and VHF antenna, separate or combined, for easy installation available.
Built-in GPS receiver for UTC synchronization and backup position fixing.

82695_Op&Ins MAN_TR2600_K 1-2
1.2 TR-2600 description
The transponder consist of:
1.2.1 Front board
The Front board consist of keyboard, LCD panel and four status lights for alarm, power, RX and
TX. The Front board communicates directly with the MMI micro controller at the Digital board.
The LCD panel displays all required information about static data, dynamic data, voyage related
data and short safety related messages. The information and messages are automatically updated
according to the necessary international standards.
1.2.2 Digital board
The Digital board consist of DSP section, Timer/MMI section, PC module and DGPS module.
DSP section
The DSP sections main task is to decode and code AIS.
Timer/MMI section
The Timer MMI section main task is to receive DGPS information and consider synchronisation of
the Tron AIS against the GPS system or against other transponders in the AIS system.
Embedded Controller(EC)
The EC module is the communication centre for the Tron TR-2600 Transponder: analysing data,
building and controlling data base, communication with external units and controlling RX and TX
messages into the right time slots.
DGPS module
The DGPS board receive GPS information from the GPS network. The internal GPS is a 12 channel
all-in-view receiver with a differential capacity, and provides UTC reference for system
synchronization to eliminate synchronisation problems among multiple users.
1.2.3 RF board
The RF board consist of three receiver units and one transmitter unit.
Two of the receiver units are TDMA receivers. One of the receiver units is dedicated to receive
DSC messages. The transmitter unit is transmitting TDMA messages.
1.2.4 Power board
The Power board consist of a DC/DC converter giving the necessary internal voltages to operate the
TR-2600.

82695_Op&Ins MAN_TR2600_K 1-3
1.2.5 Connector board
The connector board is the interface between the internal modules in Tron AIS and external units.
1.3 System overview
The AIS BS needs a controlling unit (BSC) for configuration through the Presentation Interface
(PI). The messages supported are listed in the Technical Manual.
The AIS BS unit itself has different connection types for communication on the PI:
RS-422
UDP/IP unicast (one message is per UDP-package)
IP address for the AIS BS and for the used BSC can be defined by the MMI
RS-232
TCP/IP (one message is sent per TCP-package)
The system is based on the IMO regulation for Universal AIS using Self Organized Time Division
Multiple Access technology based on a VHF Data Link (VDL).
The system is synchronized with GPS time to avoid conflict among multiple users.
The VHF channels 87B and 88B are commonly used in addition to local AIS frequencies.
The AIS BS transponders data as specified ITU on frequencies set up by the BSC.
The VHF transmit power is set automatically at 2W or 12.5W.
1.4 System standards
The TR-2600 AIS BS complies with:
IEC 61108-1 (1996)
IEC 61162-1 (2000), -2 (1998)
IEC 62320-1 draft 05.05.2004

3 AC Input Connector
Input for external AC.
AC is input between A and C, B is chassis ground.
The voltage range is from 110 to 240 VAC ± 10%.
2.6.2 Description of power operation
The AIS BS is designed to operate from both AC and DC supply. Normally AC is the main supply
and DC is the backup supply.
If both the AC and DC power supply connection are made at the Power Supply Unit, it will
automatically switch to the DC backup supply in case the main AC supply fails.
Connection to the supplies should be made with good quality power cords.
