To change these units, please refer to section 3-1 of this manual. The NS3100 DEPTH measures and displays the depth of the water. An installed NS3100 DEPTH usually has two parts: The display unit. A depth transducer, which is attached to the hull and wired to the display unit. The unit is powered from the boat's power supply. The NS3100 DEPTH is part of the Northstar family of instruments for boats, which includes instruments for speed, depth and multi. These instruments can be connected together to form an integrated data system for a boat (see section 4). For maximum benefit, please read this manual carefully before installation and use. How the transducer measures depth The depth transducer generates an ultrasonic (sound) pulse, which travels down through the water. When the pulse meets the bottom, some of the pulse is reflected back up towards the boat and is received by the transducer. The display unit analyses the reflections from each pulse. It removes unwanted reflections (from bubbles and other objects) and calculates the depth by measuring the time between sending the pulse and receiving its echo. Cleaning and maintenance Clean the display unit and any plastic transducers with a damp cloth or mild detergent. Avoid abrasive cleaners, petrol or other solvents. When repainting the hull, cover or remove any visible transducers. Depth transducers may be coated with a thin layer of antifouling paint; gently sand off any previous paint first. The NS3100 DEPTH display unit Display (backlit) Alarm symbol Display normally shows depth Depth units Four keys (backlit) 4 Northstar NS3100 DEPTH 2-1 Turn on and off Turn the unit on and off with the auxiliary power switch on the boat. The unit does not have its own power switch. When you turn it off, any settings you have made are retained. If the word SIMULATE flashes at the top, left of the display, then the unit is in simulate mode (see section 2-4). 2-2 Basic operation The keys The unit has four keys, labelled and . In this manual: Press means to push the key for less than one second. Hold for two seconds means to hold the key down for two seconds or more. Press one key + another key means to push both keys together. The display The display normally shows depth. If it displays dashes (-- --) then it means that the depth is too deep or unknown. Set backlight for screen and keys You can set the backlight to one of four brightness levels or off. Press backlight level, press again to change the level. once to display the current Backlight level 2 2-3 Alarms The NS3100 DEPTH can be set to sound an alarm when the water is too deep or too shallow (see sections 3-2 and 3-3). When the alarm sounds, the internal beeper sounds, the symbol on the display flashes and any external beepers or lights operate. Simulate mode allows you to become familiar with the unit off the water. In Simulate mode, the NS3100 DEPTH functions normally except the transducer is ignored and the unit generates this data internally. The word SIMULATE flashes at the top, left corner of the screen. Press to mute the alarm. The alarm stays muted until the depth becomes normal. The alarm will sound if the depth becomes too deep or too shallow again. 2-4 Simulate mode To turn Simulate mode on or off: 1 Turn the power off. while you turn the power on. 2 Hold down Reference Manual and Installation Manual 5 2-5 Key reference Set alarms Turn power on Hold Hold + 5 sec Reset memory Turn Simulate on or off Set Too Deep alarm Hold 2 sec Set Too Shallow alarm Hold 2 sec Decrease alarm depth Increase alarm depth Turn alarm on or off Normal operation Hold + 2 sec Setup Return to normal operation Change depth units (meters, feet or fathoms) Set Keel Offset + Increase value or change setting Mute an alarm Set Backlight Group + Decrease value or change setting Return to normal operation Adjust backlight (4 levels or off) 6 Northstar NS3100 DEPTH 3 Depth, keel offset, too deep alarm, too shallow alarm Depth and keel offset The displayed depth is the distance from the transducer on the boat to the bottom of the water, plus or minus an offset which is called the keel offset: A positive keel offset displays depth as measured from a point above the transducer. For example, if you set the offset to the distance from the transducer to the surface, it will display the depth from the surface to the bottom of the water. Keel offset Water surface Depth of transducer Transducer Note: The boat illustrated uses a through hull transducer Keel offset Positive value Negative value A negative keel offset displays depth as measured from a point below the transducer. For example, if you set the offset to minus the distance from the transducer to the bottom of the keel, it will display the depth from the bottom of the keel to the bottom of the water. 3-1 Set depth units The units can be METERS, FEET or FATH: Press ;if necessary, press again. 3-2 Set too deep alarm The too deep alarm sounds if the alarm is turned on and the depth becomes equal to or more than the too deep alarm depth.

Keel offset (negative) 8 Northstar NS3100 DEPTH 4 Systems of several instruments Several Northstar instruments can be connected together to share data. There are two ways of connecting instruments together, NavBus or NMEA. 4-1 NavBus NavBus is a Northstar proprietary system that allows systems of multiple instruments to be built using a single set of transducers. When instruments are connected by NavBus: If you change the units, alarms or calibration in one instrument, then the values will automatically change in all other instruments of the same type Each instrument can be assigned to a group of instruments (see section 6-2, step 2). If you change the backlight in an instrument in group 1, 2, 3 or 4 then the backlight will automatically change in the other instruments in the same group. If you change the backlight in an instrument in group 0 then no other vinstruments are affected. If an alarm sounds, mute it by pressing on any instrument which can display that alarm. NavBus and the NS3100 DEPTH If the NS3100 DEPTH does not have a depth transducer fitted then the unit will automatically take depth readings from another instrument, via NavBus, if the data is available. For more information, refer to the NavBus Installation and Operation manual. Note: If a transducer is not fitted to the unit and the corresponding external data is not available then the displayed value will be dashes (-- --). 4-2 NMEA NMEA is an industry standard, but is not as flexible as NavBus as it requires dedicated connections between instruments. 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. Warranty card. Mounting template. This Installation and Operation manual. 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. Through hull depth transducer. Transducer Installation manual. 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. A fuse. 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. It is vital to read this section of the manual and the documentation that comes with the other parts before starting installation. for alarms, units, calibration and backlighting are The NS3100 DEPTH can: shared (see section 4-1). Drive external beepers or lights for the alarm. Send and receive NMEA data from other Send and receive data from other Northstar instruments (see section 4-2). instruments connected via NavBus. Settings Warnings The unit is waterproof from the front. Protect the rear of the unit from water, or else water might enter the breathing hole and damage the unit. The warranty does not cover damage caused by moisture or water entering the back of the unit. Ensure that any holes that you cut will not weaken the boat's structure. If in doubt, consult a qualified boat builder. The choice, location, angle and installation of the transducers is the most critical part of the installation. If they are not correct, the unit can not perform at its designed potential. If in doubt, consult your Northstar dealer. Plastic through hull transducers are usually unsuitable for wood hulls. If in doubt, consult a marine surveyor or marine engineer. 6-1 Installation NS3100 DEPTH display unit Side view of display unit mounting 1 Choose a location for the display unit that is: 20 mm (0.75") Easily seen and protected from damage. maximum thickness At least 100 mm (4") from a compass and at least 500 mm (1.65 ft) from a radio or radar antenna.
