1 Preface This manual explains how to install the scanner and the radar processor. It also explains how to set up the radar system after installation and gives information on troubleshooting. This manual is supplementary to Revision C and Revision D of the Northstar 6100i Networked Navigation System Installation Manual Part Number GM6KIM. If the radar will be used with a Northstar 8000i system, this manual should be used with the Northstar 8000i System installation documentation for your

Only qualified personnel should install or service this equipment. Installation or servicing work that is done by non-qualified personnel can result in equipment breakdown, poor performance of the equipment, fire, electrical and physical hazards, injury or death. Wear safety equipment such as a hard hat and a safety belt at all times when installing or working on the scanner. The scanner is usually installed in an elevated position and serious injury or death can result if a person fall

2 Introduction to the Northstar radar The Northstar radars are designed as an option available to the Northstar 6000i, 6100i, or 8000i systems. A variety of scanner models are available (2 kW, 4 kW, 6 kW, 10 kW and 25 kW) to suit different customer requirements. Each scanner model has a corresponding radar processor model. 2.1 2 kW radar system overview The 2 kW radar system is intended for use in a marine environment. It consists of a dome connected to the 2 kW radar processor by a p

2.2 Check the 2 kW radar parts The RDR1021MD 2 kW radar system consists of a scanner, a radar processor, and associated cables. There are two basic options for the 2 kW radar: NS004790R is the standard 2 kW radar system, consisting of a box containing the scanner and the 49 ft (15 m) interconnection cable (NS003100). This is pre-installed into the scanner. NS004790M is the alternative 2 kW radar system, consisting of a box containing only the scanner. This radar system is designed for u

3 Install the radar 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 scanner is not rotating. However, a 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

DON'T DO THIS! DON'T install the scanner too high up, where its weight will alter the stability of the vessel and cause degradation of the radar picture over short ranges (see "How to find the optimum height for the scanner"). DON'T install the scanner close to lamps or exhaust outlets. The heat emissions may cause the equipment to breakdown and soot and smoke will degrade the performance of the radar. DON'T install the scanner close to the antennas of other equipment such as directi

However, when the power boat is traveling at high speed, the bow rises up out of the water and if the elevation angle (trim) of the bow is raised up so that it equals, or exceeds, 50% of the vertical beam width of the radar, this can cause two problems: ahead of the power boat, the beam is projected too high to sweep the water surface effectively. Targets can be missed completely or appear at a very poor resolution on the display screen. astern of the power boat, the beam is projected

3.2 How to find the optimum height for the scanner The optimum height for the scanner is as close as possible to the A-B line for best performance. How to find the A-B Line: The vertical extent of the radar beam is 2 θ°, so most of the radar beam is concentrated within this angle, meaning that outside of this angle the radar beam will be very weak. Scanner model θ° value (half the -3 dB beam width) 2 kW 15 4 kW 12.5 6 kW 10 10 kW 10 25 kW 10 An example of an A-B Line is shown

Island A is 33 ft (10 m) high (h2) and for comparison, Island B is 16.4 ft (5 m) high (h2). Both islands are at a distance (D) of 10 nautical miles from the vessel.

The 2 kW scanner dimensions are shown: 3.6 Install a scanner on a trestle Depending on your chosen location for the scanner, it may be easier to install the scanner if you fabricate a trestle (or radar mast) on which you

Orient the trestle so that the cable inlet on the scanner will face the stern, and so that the scanner can be mounted at the correct angle (as discussed in the "Power boat installation" section). Make sure that the edges of the trestle won't trap water. 3.7 Install the 2 kW scanner unit IMPORTANT: Remember that you must screw the bolts into place from the underside of the location site, because the shape of the dome prevents you from installing the bolts from the topside. Ensure that

3.8 Install the radar processor Install the radar processor in a dry location away from spray, rain, drips, and condensation. The location site must allow you to easily connect the radar processor to the ship's ground, the interconnection cable, the power cable, and the 6000i and 6100i radar communications cable or the 8000i network cable. Check that these cables and the ship's ground can easily reach the radar processor BEFORE you drill. The radar processor dimensions are shown on the
