The Automatic Identification System (AIS) is a Very High Frequency (VHF) radio broadcasting system that transfers packets of data over the VHF data link (VDL) and enables AIS equipped vessels and shore-based stations to exchange identification information and navigational data. Ships with AIS transponders continually transmit their ID, position, course, speed and other data to all nearby ships and shore stations. Such information can aid greatly in situational awareness and provide a means to assist in collision avoidance. AIS equipment is standardized by ITU, IEC, IALA and IMO and is subject to approval by a certification body. The following AIS devices have been developed for variant applications. AIS Class A:

mandated by the IMO for vessels of 300 gross tonnages and upwards engaged on international voyages, cargo ships of 500 gross tonnages and upwards, as well as passenger ships. It transmits typically on 12.5 watts output power. AIS Class B:

provides limited functionality and is intended for non-SOLAS commercial vessels and recreational vessels. It transmits typically on 2 watts output power. AIS Receiver:

only receives AIS signal and it does not have transmitter to send out AIS signal. Suitable for recreational vessel that does not want to send out its vessel information. AIS Base Station:

is provided by aids-to-navigation authorities to enable the ship to shore / shore to ship transmission of information. Networked AIS Base Stations can assist in providing overall maritime domain awareness. AIS AtoN (Aids to Navigation):

provides an opportunity to transmit position and status of buoys and lights through the same VDL, which can then show up on AIS-ready devices within the range. AIS SART:

Search and Rescue Transmitter using AIS can be used to assist in determining the location of a vessel in distress. It is typically used on life rafts. AIS on Search and Rescue (SAR) Aircraft:

used on airplanes and helicopters to assist search and rescue operation. 10 SYSTEM OVERVIEW Product Description The AMEC model A750 is a new generation AIS Class A transponder fully compliance with IMO, IEC, and ITU international standards. It provides a compact single box solution, easy to install and operate. The product is designed with advanced technology which sets a new standard for quality, performance, and value. It is an excellent choice for SOLAS vessels, commercial ships, professional vessels, and non-

SOLAS applications. The A750 can be connected to the ships sensors as required by the IALA guidelines through junction box. The device can also interface external navigation and presentation systems that support IEC 61162-1 related sentences. It is also capable for connection to Long Range system like Inmarsat C. The A750 supports both SOLAS and Inland AIS mode which is configurable by the software. The color LCD display and menu keypads provide an intuitive graphical user-friendly interface to the system. It can display the location of other vessels, aids to navigation and search and rescue vessels.

VHF Antenna Cable Type: 5D-FB or equivalent Connector: PL-259 (Male) GPS Antenna Cable Type: RG58A/U or equivalent Connector: TNC (Male) Cable and connector are supplied as part of the GPS antenna. 14 VHF Antenna Installation The quality and positioning of the antenna are the most important factors dictating AIS performance. It is recommended that a VHF antenna with omni directional vertical polarization be specifically tuned for AIS operation band. Since the range of VHF signals is largely decided by line of sight distance, the VHF antenna should be placed as high as possible and at least 5 meters away from any constructions made of conductive materials. To avoid interference, the VHF antenna location should be placed accordingly as diagram below:

Figure 1 VHF/GPS Antenna Locations 15 GNSS (GPS) Antenna Installation The GPS antenna must be installed where it has a clear view of the sky, so that it may access the horizon freely with 360 degrees, with a vertical observation of 5 to 90 degrees above the horizon as illustrated below. GPS ANTENNA LOCATION Enter the GPS antenna location data in SHIP SETTING after the installation. Figure 2 GPS Antenna location Mounting A750 Use the following guidelines to check the installation location for your AIS transponder:

The AIS transponder should be mounted in a location that is accessible and readable to user at all time. The transponder should be installed in a protected environment away from direct rain and water contact. The transponder is designed to operate in an environment with -25C ~ 55C temperature. Environments with excessive heat may cause damages to the transponder. The transponder should not be installed near flammable or hazardous environments. The AIS transponder should be installed at least 0.5m away from magnetic compasses. 16 B C D A Mounting A750 Transponder Main Unit Figure 3 Mounting A750 Main Unit Panel Mounting (1) 1.

Due to the complexity of the operation environment of marine electronics, it is recommended to minimize all possible interference sources before proceeding with the troubleshooting by Disconnecting other NMEA equipment from the AIS transponder such as ECDIS, heading or gyro etc. Switching off other emission sources such as radar or VHF radio. Symptom The transponder will not power on No GPS position fix No AIS transmission AIS range seems too low No AIS targets on radar view and target list Sensor or Data ports not response Possible cause and remedy Check that the voltage of the power supply has 12V or 24V. Check that the polarity is not switched. Check that the available current is sufficient for start-up. Check that the power connector is correctly connected and secured. Increase Dimmer level of the display. Check for failed GPS antenna, damaged antenna cable and connectors When the transponders internal GPS does not have a position fix, the time and date appearing in the upper right corner of the display will not be correct. Check the GNSS status to see the received satellites and their noise ratio. Make sure that MMSI number is correctly configured. Make sure that silent mode is switched off. Check that the available current is sufficient for transmission. Check if the transponder might be operating in a regional area set with different operating mode. Check VHF antenna and cable installation Make sure the transponder is not operating in low power

(1W) mode. Check if VHF antenna, cabling and connector installations are damaged. Check that wiring polarity is not switched Check that the transponder and the connected sensor have the same baud rate 93 Troubleshooting with alarm messages The A750 is monitoring itself constantly for failures or other important parameters with the built-in integrity test (BIIT). In case an abnormal operation is detected in one or more of the following conditions, an alert will be triggered and displayed on the screen, and the transponder will react as described in the following table. Description text AIS: Tx malfunction The A750 has a built-in lock detector (high active) to monitor the local oscillator (PLL circuit) of the transmitter. If the operation of PLL circuit becomes abnormal, a logic low (Tx malfunction) will be sent from the lock detector to notify the system. At the same time, system will output an BIIT ID 001 alert at the related PI port. AIS: Antenna VSWR exceeds limit The A750 has a built-in RF output power detector to monitor the VSWR (Voltage Standing Wave Ratio) of the VHF antenna port. If the antenna VSWR exceeds a given limit, an alarm will be generated. If the VSWR goes below the defined threshold, the alarm is cleared. AIS: Rx channel 1 malfunction The A750 has 3 built-in lock detectors (high active) to monitor each local oscillator (PLL circuit) of receiver channel 1, channel 2, and channel 70 respectively. If the operation of PLL circuit becomes abnormal, a logic low level will be sent from the lock detector to notify the system. At the same time, the system will output BIIT ID 003, BIIT ID 004 or BIIT ID 005 alert to indicate the CH1 or CH2 or CH70 RX malfunction respectively. AIS: Rx channel 2 malfunction AIS: Rx channel 70 malfunction AIS: general failure AIS: UTC sync invalid 94 BIIT ID 001 Reaction of the system

(transponder) Stop transmission 002 Continue operation 003 Stop transmission on affected channel 004 005 006 007 Stop transmission on affected channel Continue operation Stop transmission Continue This alarm is triggered when the transponder lost UTC direct synchronization or cannot synchronize from the internal GPS receiver. AIS: MKD connection lost This alarm is active if the communication between the control unit and the display in the transponder does not work. AIS: internal / external GNSS position mismatch This alarm is active if the difference between the internal and external GNSS position is more than 100m for more than 1 hour. AIS: NavStatus incorrect For example, if the navigational status is set to At Anchor but the ship is moving faster than 3 knots, this alarm will become active. Heading sensor offset This alarm is active when SOG is greater than 5kn and the difference between COG and HDT is greater than 45o for 5 min. AIS: active AIS SART This alarm is active when the transponder receives an AIS SART position report. AIS: external EPFS lost This alarm is active if the position from the external Electronic Position Fixing System is invalid. AIS: no sensor position in use This alarm is active if there is no valid position from any sensor is available. AIS: no valid SOG information This alarm is active if the transponder does not have a valid SOG from any sensor AIS: no valid COG information This alarm is active if the transponder does not have a valid COG from any sensor AIS: Heading lost/invalid This alarm is active if either the heading info from external sensor is lost or if the heading is undefined. AIS: no valid ROT information This alarm is active if ROT is undefined or if no valid ROT info is available. 95 operation using indirect or semaphore synchronization Continue operation 008 009 Continue operation 010 Continue operation 011 Continue operation 014 Continue operation 025 Continue operation 026 Continue operation 029 030 032 035 Continue operation using default data Continue operation using default data Continue operation using default data Continue operation using default data Appendix A: Technical Information - Data Interface AIS Interface Overview Figure A1 AIS Interface Overview 96 A750 Data Interface (IEC 61162-2) The A750 Class A AIS Transponder provides 2 types of IEC 61162-2 data interfaces for user applications. The first interface type includes 3 input-only sensor data ports and the second interface type includes 4 bidirectional input/output ports. Data port for each interface type will be described in the following section. Sensor Data Input Ports The schematic of input-only sensor data port is shown in Figure A1. The schematic includes an isolated half duplex RS-485 transceiver IC which is used as the main component to receive external data. The transceiver IC is isolated from external input. To avoid signal reflection, the transceiver IC has an optional built-in 120 loop termination, which is selectable by the dip-switch on the junction box and the switch should be set to on position when connecting external data source with long cable. All sensor data-input ports are isolated from one another and are also isolated from internal power supply. The input impedance on A/B wires is greater than 12 K and the levels on the A/B wires are defined in the following:

Logic low input: A-B < -0.2V Logic high input: A-B > -0.02V Figure A2 Schematic of sensor data input port. 97 Bidirectional Data Ports The schematic of bidirectional data port is shown in Figure A2. The schematics includes an isolated full duplex RS-485 transceiver IC which is used as the main component to handle both data input and output from external data source. The transceiver IC is isolated from external input. To avoid signal reflection, the transceiver IC has an optional built-in 120 loop termination, which is selectable by the dip-switch on the junction box and the switch should be set to on position when connecting external data source with long cable. All bidirectional data ports are isolated from one another and are also isolated from internal power supply. The transceiver internal power supply is fully isolated from the external power supply.
