Always stay away from any type of radar antenna to avoid exposure to radiation! An open array antenna may start rotating at any time. Before starting antenna operation, always move all personnel away from the antenna to prevent accidents. It is highly recommended that an open array antenna be installed as high as possible (such as on the fly bridge, radar mast, etc.) so that no person can ever be near enough to sustain injury. The Northstar Ethernet Radar is designed as an option available for the Northstar 972 navigator. A radar unit should only be installed by a qualified marine technician, as potentially lethal high voltage is present, along with heavy rotating parts. There is a transmit interlock that prevents radar transmissions if the array is not rotating. However, high voltage remains for a period of time after the system is turned off. If you are not familiar with this type of electronics, consult with a trained service or installation technician before attempting to service any part of the equipment. Installation includes mechanical mounting and electrical wiring, followed by properly configuring the navigator to work with the radar, and finally adjusting the radar for proper performance. Don't take any shortcuts, and follow these instructions carefully. NOTE: For the radar overlay to function properly on the chart screen, you must correctly install and calibrate a separate heading sensor (using the navigator's NMEA Input Port 1 interface connector, pins 1 and 3). Without the heading sensor, the radar image will not line up properly with the chart. The Northstar 972 accepts the following standard NMEA 0183 sentences to obtain heading information from a sensor: HDG, HDT, OSD, HCC, HCD, and HDM. For sensor installation and calibration instructions, see the sensor manufacturer's installation manual. In addition, the navigator must be calibrated to the heading sensor as described on page 21. Components supplied with each of the five radar models are listed on the next page. Ethernet Radar Installation Manual, Rev.

A Page 3 SECTION TWO: Installing and wiring the radar Installing the radar antenna CAUTION! To eliminate interference, install the antenna away from GPS and radio receiver antennas, including SatNav and satellite TV antennas. Choosing the antenna location The radar's ability to detect targets depends greatly on the position of its antenna. The ideal antenna location is high above the ship's keel line where there aren't any obstacles. This ideal location is limited by various factors; therefore, consider the following when choosing the antenna location: · Do install the antenna as high as possible (after considering the structure of the vessel's hull, the weight of the antenna, and how easy it will be to maintain the antenna). The higher the installation position, the longer the radar ranging distance. · Do install the antenna away from masts or other obstructions. If the antenna isn't higher than obstructions, radar waves may be blocked, creating shadow zones or generating false echoes. · Do install the antenna closer to the vessel's bow, for a clear view to the front. When installing the antenna on a mast, place it in front of the mast. If obstacles can't be avoided for vessel structural reasons, see "Shifting the antenna away from the keel line," described below. · Do install the antenna as far away as possible from the antennas of other equipment, such as direction finders, GPS equipment, radio receivers, etc. Radar scanners may cause interference with radio receivers. · Do keep the connecting cable as short as possible. Whenever possible, keep the distance from the antenna to the control box within the standard cable length of 10 meters. If you must use longer cable, do not exceed 30 meters. · Don't install the antenna where it may be subjected to smoke or hot air from smokestacks or heat from lamps. Shifting the antenna away from the keel line By shifting the antenna position from the keel line to starboard, it's possible to move shadow zones to the port side. This makes it possible to keep a clear view to the bow. You can calculate the distance to be shifted, depending on the distance from the antenna to any obstacles, by using the following equation (Ls = distance to be shifted from keel line; D = diameter of obstacle on keel line; and R = distance from antenna to obstacle): Ls=0.4R+D/2 (when R<15m) Ls=0.025R+D/2 (when R>=15m) Page 4 Ethernet Radar Installation Manual, Rev. A SECTION TWO: Installing and wiring the radar Figure 2: Shifting from the keel Obtaining sufficient dip angle Raise the antenna position above on-board obstacles to avoid shadow zones. Dip angle is the angle between a horizontal line and the line of sight from the antenna to the obstacle. By maintaining a dip angle greater than 5 degrees, you may be able to prevent mid- and long-distance shadow zones. The radar can't detect objects below its line of sight. Figure 3: Sufficient dip angle Mounting the radar antenna It may be easier to install the antenna by fabricating a mounting base, as shown below, but you can also install the antenna directly to a rigid, flat surface, such as the roof. Pay attention to the water drain tube at the bottom of the antenna. Figure 4: Using a mounting base Ethernet Radar Installation Manual, Rev. A Page 5 SECTION TWO: Installing and wiring the radar NOTE: When the radar platform or mounting bracket has a curvature of more than 2mm, repair it or use spacers. Referring to Figure 5 below and the supplied full-size antenna mounting templates, drill holes at the specified locations in the mounting base. Using these holes and hexagonal bolts, install the antenna to the mounting base. Use silicone to stop the bolts from loosening. The bolts supplied will suffice for mounting base thicknesses of 0.35 to 0.55 inch (9 to 14 mm). If the mounting base is thicker or thinner than that, use bolts specified in Table 3 or Table 4 on page 7. See Figure 6 or Figure 7 below for details on bolting the antenna to the mounting base.
