8 8.1 Installation Mechanical Mounting 8.1.1 Transponder unit Use the standard Mounting Kit. For dimensions and positioning of holes see Figure 14-1 TR-8000 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 were it can be directly exposed to seawater as corrosion then may appear and cause leakage. 3.
8.1.2 Display Unit The display unit can be installed as desktop mounted, roof 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 were 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.
8.1.2.2 Roof Mounting When display unit is mounted overhead/roof, it might be necessary to adjust Contrast/Brightness, see chapter 7.
8.1.2.3 Flush/ Panel Mounting Figure 8-4 Flush mounted Display Unit, exploded view.
8.1.3 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 8-5 Horizontal separation distance. VHF antenna for AIS: VHF antenna for AIS: See subchapters below for detailed description > 2.5 meters > 2.
8.1.3.1 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.
8.1.3.1.2 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 8.
.1.3.2 VHF Antenna When individual GPS antenna is used, the additional VHF antenna must also be connected For detailed description of this antenna, see Chapter 14 Outline Drawings 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.
8.2 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.
8.2.2 VHF antenna The table below shows the attenuation on the VHF frequencies with different cable types: Cable Type RG214 RG225 Attenuation @150 MHz (dB/100m) 7 8 Diameter (mm) Weight (kg/100m) 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.
8.3 Wiring and Connections Figure 8-8 Block diagram of typical connections Wiring and connection of Antennas (GPS + VHF) are described in chapter 8.1.
8.3.1 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.

8.3.1.4 Sensor connections Sensors like GPS, Gyro, Speed log etc may be connected to the 3 different sensor inputs in the TR-8000 Transponder unit. Recommended cable diameter: 0.25 - 2.
8.3.1.5 External display – ECDIS/Radar connections The TR-8000 have a very flexible solution when it comes to connecting ECS/ECDIS, Modern Radar or Chart plotter for displaying AIS data on a more advanced display than the TR-8000 Display unit, which only gives you basic text/graphic information. On modern ECS, Radars, Chart plotters etc.
8.3.1.6 Pilot / Aux. Display connection This Port may be mandatory to be used with Pilot port connector (See picture below) on some kind of vessels. Otherwise, this port may be used to connect a secondary display (Maybe ARPA radar, if “External display” is connected to ECS/ECDIS) This port is one of two options to connect a Pilot connector, as it is also possible to connect Pilot port cable to the TR-8000 Display Unit, see chapters 8.3.2 and 10.2.1.
8.3.1.7 Alarm Connection Below picture shows where to connect external alarm to TR-8000 # 37 38 In/Out Type Out Relay (NO) Out Usage Alarm Name ALARM_A ALARM_B In this configuration, both the external relay and the alarm unit are powered from external power source, and the alarm unit is grounded through the external relay if an alarm occurs or the main power to the AIS is removed or defective.

It is assumed that no SD card is present in the transponder SD card reader. a. To reset the IP settings for the transponder and the connection to the display to default values if these setting have been reconfigured and are unknown: Press the upper right preset button and apply power.

- Not subject to target loss due to fast manoeuvres. Able to detect ships within VHF/FM coverage. IMPORTANT When using the AIS for anti-collision purposes it is important to remember that the AIS is an additional source of navigation information. It does not replace other navigational systems. The AIS may not always give the right picture of the traffic in your area separately. 9.4 Erroneous information Erroneous information implies a risk to other ships as well as your own.
10 Operation Instructions 10.1 Configuration Menu The AIS configuration menu consists of six menus, containing the settings and configurations most applicable to the user. Some settings are write-protected by administrator password, but the user is always allowed to view the current settings. 10.1.1 Own Ship The own ship configuration is for setting the static data of the ship and is primarily only used during setup/installation but should also be checked regularly (at least once a month).
10.1.1.
10.1.1.2 Ship Dimension and Antenna Position In order to calculate the correct location of own ship relative to other ships, the exact position of the GNSS antennas and the dimension of the ship need to be specified. The setting of the Ship Dimensions and the Antenna positions are combined as follows: A: Distance from bow to GPS antenna position in meters. B: Distance from stern to GPS antenna position in meters. C: Distance from port to GPS antenna position in meters.
10.1.2 Display Settings Red square shows button selected to get to next menu 10.1.2.1 Sleeping Targets The first “Display settings” menu configures “Sleeping targets” based on: Range Class B The “sleeping targets” may not be shown “Views” may be configured by pressing this button on the “Button Bar” 10.1.2.2 Views Here we can configure which columns shall be shown in “Ships List” (chapter 7.2.6) and if we want “Head up” or “North up” in “Graphical view”(chapter 7.2.7).
10.1.3 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. Altering the regional settings is protected by a user password.
10.1.3.2 View Regions It is possible to view the settings of a given region by selecting a region in the regions list and pushing the View Region button. Example of standard TR-8000 without any extra Regions defined Example configuration with one extra Region defined Red square shows button selected to get to next menu 10.1.3.2.
