See Table on page 36 for reference. 5.4.7 Draught The Draught parameter specifies the maximum depth of the ship in meters.
6 Installation 6.1 Mechanical Mounting 6.1.1 Transponder unit Use the standard Mounting Kit. For dimensions and positioning of holes see Figure 14-1 MX535B Transponder Unit- mechanical dimensions. When selecting a mounting location for the Transponder the following guidelines apply: 1. Keep the transponder out of direct sunlight. 2. Do not mount the transponder where it can be directly exposed to seawater as corrosion then may appear and cause leakage. 3.
6.1.2 MX51X Display Unit The display unit can be installed as bracket mounted or flush mounted in a panel. Installation shall be near the conning position. When selecting a mounting location for the Display Unit the following guidelines apply: 1. Do not mount the display unit where it can be directly exposed to seawater as corrosion then may appear and cause leakage. 2. The unit must not be mounted near exhaust pipes and vents. 3.
6.1.2.2 Flush/ Panel Mounting Figure 6.
6.1.3 Antennas As a general rule, longer horizontal distances to other antennas will minimize the interference and improve reception on all antennas. Minimum distance is described in the figures below: Other VHF antenna or GPS antenna VHF antenna for AIS: >10 meters Figure 6.4 Horizontal separation distance. VHF antenna for AIS: VHF antenna for AIS: See subchapters below for detailed description >2.5 meters Other VHF Antenna >2.5 meters >0, 5 meters GPS Antenna >0, 5 meters >0, 5 meters Figure 6.
6.1.3.1 GPS Antenna When selecting a mounting location for the antenna, keep in mind the following points. 1. Select a location out of the radar beam. The radar beam will obstruct or prevent reception of the GPS satellite signal. 2. There should be no interfering object within the line-of-sight to the satellites. Objects within the line-of-sight to a satellite, for example a mast, may block reception or prolong acquisition time. 3.
6.1.3.1.2 Combined VHF/AIS As an option to the individual VHF and GPS antennas, a combined antenna may be used in conjunction with a signal splitter which will provide a common cable between the signal splitter and the antenna, and two short jumper cables between splitter and transponder. The combined antenna is delivered with a mounting bracket to be mounted on a mast. Calculation of cable length/attenuation etc… is described in chapter 6.
6.1.3.2 VHF Antenna When individual GPS antenna is used, the CX4 VHF antenna must also be connected. Location of the mandatory AIS VHF-antenna should be carefully considered. Digital communication is more sensitive than analogue/voice communication to interference created by reflections in obstructions like masts and booms. It may be necessary to relocate the VHF radiotelephone antenna to minimize interference effects.
6.2 Cabling All outdoor installed connectors on coaxial cables should be fitted with preventive isolation such as vulcanizing tape to protect against water penetration into the antenna cable. Coaxial cables should be installed in separate signal cable channels/tubes and at least 10 cm away from power supply cables. Crossing of cables should be done at right angles (90°). The minimum bend radius of the coaxial cable should be 5 times the cable's outer diameter.
6.3 Wiring and Connections The table below shows the attenuation on the VHF frequencies with different cable types: Cable Type RG214 RG225 Attenuation @150 MHz (dB/100 m) 7 8 Diameter (mm) Weight (kg/100 m) 10.8 10.9 18.5 23.3 Example: A RG 214 cable with length of 40 meters will have an attenuation of 2.8 dB. Please keep the cables as short as possible, and be aware that 3 dB losses mean only half the output power. If you have a transmitter delivering 12.
6.3.2 Wiring Figure Figure 6.8 Block diagram of typical connections Wiring and connection of Antennas (GPS + VHF) are described in chapter 6.1.
6.3.3 Transponder In order to connect all sensors and external connections to the Transponder Unit, the lid must be removed by removing the screws on top of the unit. Pay attention to the seal gasket on the inside of the lid and the small O-ring positioned on the center screw. These gaskets need to be in place when mounted in order to keep the unit waterproof. When the lid is off, the connections to sensors, ECS etc… can be made. The inner lid shall not be removed by user. Figure 6.

At the end of editing, press the EDIT key to exit. 8.2 Regional settings The regional settings are primarily used by local base stations to assign special frequencies or transmitter configurations for certain areas. It is also allowable to add or edit the regions, but this should be done with caution, as incorrect frequency settings for an area will disable the functionality of the AIS system.
8.2.1 Transition Zone A Region must be between 20 and 200 Nautical miles and within this region there will be a “Transition zone” between 1 and 8 Nautical miles: This zone is used for frequency transition so only one frequency is changed at a time. There are defined rules for how the AIS will behave through this zone. The AIS will continuously monitor for its own position and range to the regional areas defined. By entering transition Zone of Region 1, frequency is changed on the primary channel.
8.2.
8.2.3 AIS Alarms The AIS Alarm is triggered if a failure is detected in one or more of the AIS functions or data. The corresponding message is given in table below. The most probable source of error and corresponding system behavior is described together with some notes on troubleshooting the error. Alarm Description ID 001 Tx malfunction Cause / Source of error VHF Antenna or cabling The Transponder stops transmission. mismatch. Alternatively Check the antenna cabling for short or open circuits.
009 Internal / external GNSS position mismatch Internal or External GPS or Antennas The Transponder continues operation, but as this might imply that wrong position is used. Care should be taken as this might impose a risk both for own and other ships. Check the positioning of the GPS antennas. Disconnect the External GPS and check if the internal GPS provides the correct position. 010 Navigational Status incorrect Setup or speed sensor The Transponder continues operation.
035 No valid ROT information External rotation sensor The Transponder continues operation using default data. Check wiring and external sensor. Check baud rate settings.

8.2.7 Silent Mode Silent Mode The silent mode is a special mode for travelling in areas where the transmission of own position impose risk to the user. When active, no signals are sent from the Transponder unit, but the user is still able to receive information from other vessels. CAUTION: The Silent Mode disables the AIS Transmitter functionality and will make the Vessel invisible on the AIS system and impose a risk to own and other vessels.
8.2.8 Test VHF transmission The communications test is used to verify the operation of the VHF communication by transmitting a request for an acknowledgement to another ship (a.k.a. “pinging”). The user can select an AIS target from the list in AIS 2 screen as long as the target is a Class A AIS transponder and “ping” it. This can be done under the AIS 4 screen. You can send a TEST text message to any class A AIS target and hopefully it will send an acknowledgement message back.

14 Abbreviations and Definitions VHF/GPS-B GPS Marine Antenna VHF/GPS-B is a VHF marine antenna with a helix GPS antenna for the frequency 1575.42 MHz incorporated. The VHF/GPS -B is manufactured in premium quality materials in order to prevent galvanic corrosion. VHF/GPS-B is subject for improvement at all times. The antenna has the same rugged design as all other AC Marine antennas thus it withstands harsh environmental conditions. Electri cal Specifications: Frequency range (MHz) 156.0-162.5/1575.
ACK Acknowledge AIS Automatic Identification System - A ship borne broadcast transponder system in which ships continually transmit their position, course, speed and other data to other nearby ships and shoreline authorities on a common VHF radio channel. AIS-SART Automatic Identification System-Search and Rescue Transponder AtoN Aid to Navigation BAUD Transmission rate unit of measurement for binary coded data (bit per second).
GMDSS Global Maritime Distress Safety System HDG Heading - The direction, in which the vessel is pointed, expressed as angular distance from north clockwise through 360 degrees. HEADING should not be confused with COURSE. The HEADING is constantly changing as the vessel yaws back and forth across the course due to the effects of sea, wind, and steering error.
RMS ROOT MEAN SQUARED – A statistical measure of probability stating that an expected event will happen 68% of the time. In terms of position update accuracy, 68 position updates out of 100 will be accurate to within specified system accuracy. ROT Rate Of Turn RNG Range RX RX is the telegraph and radio abbreviation for “receive” SAR Search And Rescue SNR Signal-to-Noise ratio (SIN). Is the quantitative relationship between the useful and nonuseful part of the received satellite signal.
