Depth data is output by the NS3100 DEPTH and can be read and displayed by the Northstar MULTI 3100 or other NMEA instrument. Reference Manual and Installation Manual 9 5 NS3100 DEPTH hardware 5-1 What comes with your NS3100 DEPTH The NS3100 DEPTH comes in several configurations. Standalone configuration NS3100 DEPTH unit with protective cover. In addition, the standalone configuration usually requires a depth transducer (see section 5-3). Kit configuration The NS3100 DEPTH is available in several kit configurations with different grades of through hull transducer, with: The parts for the standalone configuration, listed above. Optional external beepers or lights can be fitted. The NS3100 DEPTH output is switched to ground, 30 V DC and 250 mA maximum. If the beepers and lights require more than 250 mA, fit a relay. For systems of several instruments, wiring and connectors are required (see section 4 or the NavBus Installation and Operation manual). A bronze transducer is suitable for wood or fibreglass hulls. Never install a bronze transducer in a metal hull, because it will cause electrolytic corrosion. A range of Northstar through hull transducers are available, plus in hull and transom mount transducers. For more information, refer to the Transducer Installation manual or consult your Northstar dealer. 5-2 Other parts required One or more NS3100 series instruments will be connected to the boat 12 V power supply via: An accessory switch to turn the instruments on and off. Use a 1 A fuse for between one and five instruments. 5-3 Transducer The NS3100 DEPTH is usually used with a through hull depth transducer. However, the unit can take readings from another instrument, in which case it may not need a transducer (see section 4). A through hull transducer generally gives the best performance and is the best choice for displacement hulls. It is mounted in a hole drilled through the bottom of the boat. A plastic through hull transducer is suitable for GRP or metal hulls. Plastic through hull transducers are not suitable for solid wooden hulls (use Northstar's bronze transducers). 5-4 Accessories These accessories are available from your Northstar dealer. 4 m (13 ft) depth transducer extension cable NavBus junction box (See section 4) 10 Northstar NS3100 DEPTH 6 Installation and setup Correct installation is critical to the performance of the unit.
