It can calculate and display average speed, maximum speed, trim speed, trip log (distance) and total log. An installed NS3100 Multi usually has two parts: The display unit. Depth and speed / temperature transducers which are attached to the hull and wired to the display unit. The unit is powered from the boat's power supply. The NS3100 Multi is part of the Northstar family of instruments for boats, which includes instruments for speed, depth, wind and repeaters. These instruments can be connected together to form an integrated data system for a boat (see section 8). 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 NS3100 Multi display unit 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. How the transducer measures speed The speed transducer has a small paddlewheel which spins as the boat moves through the water. The transducer measures how fast the paddlewheel is spinning and calculates the boat speed by averaging several measurements. 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. 4 Northstar NS3100 MULTI 2 Operation 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 SIM flashes at the bottom, right of the display, then the unit is in simulate mode (see section 2-5). 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. Change the items displayed The display can show two values at once, one in the top part of the screen and one in the bottom. If an item displays as dashes (-- --) then it means that the value is outside the range, for example the depth might be too deep or unknown.

When the alarm sounds, the internal beeper sounds, the symbol on the display flashes and any external beepers or lights operate. Press to mute the alarm. The alarm stays muted until the depth becomes returns to the pre-alarm condition or is within the alarm parameters. The alarm will sound if the depth becomes too deep or too shallow again. 2-5 Simulate mode Simulate mode allows you to become familiar with the unit off the water. In Simulate mode, the NS3100 Multi functions normally except that the transducers are ignored and the unit generates this data internally. The word SIMULATE flashes at the bottom, right corner of the screen. To turn Simulate mode on or off: 1 Turn the power off. 2 Hold down while you turn the power on. 6 Northstar NS3100 MULTI 2-6 Key reference Turn power on Set alarms Hold Hold + 5 sec Turn Simulate on or off Reset memory Set Too Deep alarm Hold 2 sec Set Too Shallow alarm Hold 2 sec Turn alarm on or off Increase alarm depth Decrease alarm depth Return to normal operation Normal operation Hold + Change top display (Speed, Avg speed, Max speed, Trim speed, Depth, Temperature) Change bottom display (Speed, Depth, Log, Total log, Battery voltage, Countdown timer) Mute an alarm Adjust backlight (4 levels or off) Reset top value to zero (Avg speed, Max speed, Trim speed) Reset bottom value to zero (Log, Total log (hold for 5 sec) Start or stop countdown timer) Change units of top value (e.g. knots, metres, °C) Change units of bottom value (e.g. knots, metres) 2 sec Setup Set Speed Damping + Set Countdown Timer Start Time + Set Keel Offset + Set Temperature Calibration + Mode is SEn + Set Speed Mode Sen(sor) or GPS Set Speed Calibration + Set Log Calibration Mode is GPS + Set Speed Resolution + Set Backlight Group + Increase value or change setting Decrease value or change setting Return to normal operation + + Hold 2 sec Hold 2 sec Reference Manual and Installation Manual 7 3 Speed, average speed, maximum speed, trim speed The unit can display several speeds: Speed: The current boat speed. Avg speed: The average speed since Avg speed was reset or the unit was switched on. Max speed: The maximum speed since Max speed was reset or the unit was switched on. Trim speed: Trim speed may be used for tuning racing boats. Trim speed measures changes in boat speed, relative to when you reset trim speed to zero. For example, if the boat is travelling at 10 knots and you reset trim speed, then trim speed is zero. Then: If the boat speed increases to 11.5 knots, the trim speed is 1.5 knots. If the boat speed decreases to 8.5 knots, the trim speed is -1.5 knots. 3-1 Set speed and log units The speed units can be selected to be KNOTS, KPH and MPH. Selecting one of these automatically sets the log distance units to NM, KM or M (miles): until Speed is displayed, then hold Press until the units change; if necessary, hold again until the units change again. 3-2 Reset average speed Resetting makes the NS3100 Multi calculate a new average speed: until Avg speed is displayed. 1 Press 2 Press + . 3-3 Reset maximum speed Resetting makes the NS3100 Multi calculate a new maximum: 1 Press until Max speed is displayed. 2 Press + . 8 Northstar NS3100 MULTI 3-4 Reset trim speed Resetting sets the trim speed to zero: 1 Press until TRIM speed is displayed. 2 Press + . 3-5 Set speed damping Waves and wind cause the boat speed to fluctuate slightly. To give a stable reading, the NS3100 Multi calculates the boat speed and trim speed by measuring the speed several times and averaging the measurements. The speed damping value ranges from 1 to 5: A lower value averages readings over a shorter period of time. This gives the most accurate speed but has the most fluctuations. A higher value averages readings over a longer period of time. This gives the most stable speed but will ignore some true speed changes. Set the speed damping to the lowest value which gives a stable speed reading. Values of 1, 2, 3, 4 and 5 average readings over a time period of 6, 12, 18, 24 and 30 seconds respectively. To get the most accurate, stable trim speeds, you may need to increase the damping. To set speed damping: 1 Press + several times until the Speed Damping screen is displayed. or to change the damping. 2 Press 3 Press . Damping equals 3 3-6 Set speed resolution This sets how speeds are displayed. It has two settings: 0.0 Displays speeds as 0.0 to 19.9, 20 up. 0.00 Displays speeds as 0.00 to 19.99, 20.0 to 29.9, 30 up. To set the speed resolution: 1 Press + several times until the Speed Resolution screen is displayed. or to change the resolution setting to 2 Press 0.0 or 0.00. 3 Press . Value equals 0.0 or 0.00 Reference Manual and Installation Manual 9 3-7 Calibrate speed Calibration may be required, because different hull shapes have different water flow characteristics. Speed calibration can be done either by the speed or by the log, as described below. If speed readings are taken from a GPS receiver (see section 8-1), then you can not calibrate it. Calibrate by speed In this method, travel at a measured, constant speed. Use the speed displayed on a GPS receiver, follow another boat travelling at a known speed or make a timed run over a known distance. Note that for accurate calibration: The speed from a GPS receiver should be above 5 knots. The speed from another paddlewheel transducer e.g. another boat - should be between 5 and 20 knots. Best results are achieved in calm conditions where there is minimal tidal current (best at high or low tide). Continue travelling at this measured, constant speed and calibrate the speed as follows: 1 Press + several times until the Speed Calibration screen is displayed (after this, it does not matter if the boat speed changes). or to change the displayed speed to 2 Press the measured boat speed. 3 Press . Calibrate by log In this method, travel a known distance in a straight line over a course. Best results are achieved in calm conditions where there is minimal current (best at high or low tide). Tidal effects may be reduced by making the trip twice, parallel to the current, once in each direction. 1 At the start of the course, reset the trip log (see section 4-1). Travel in a straight line over the course, then repeat in the other direction. 2 At the end, note the trip log distance (see section 4). 3 Press + several times until the Log Calibration screen is displayed. 4 Press or to change the displayed distance travelled to the actual distance you travelled over the course. 5 Press .

TOTAL LOG: Total distance. The distance travelled since total log was reset: The log units are NM, KM or M (miles) and correspond to the speed units, for example if you set the speed units to KPH then the log units are KM (see section 3-1). Total log 4-1 Reset log Resetting zeros the log (trip distance): until LOG is displayed. 1 Press 2 Press + . 4-2 Reset total log Resetting zeros the total log (total distance), as well as the log and avg speed: until TOTAL LOG is displayed. 1 Press for 5 seconds. 2 Hold + Reference Manual and Installation Manual 11 5 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 as 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 negative offset as 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. 5-1 Set depth units The units can be METERS, FEET or FATH: Press until DEPth is displayed, then hold until the units change; if necessary, hold until the units change again. 5-2 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.

There are two ways of connecting instruments together, NavBus or NMEA. 8-1 NMEA NMEA is an industry standard. Speed, depth, temperature and log data may be output which can be read and displayed by any compatible Northstar (eg. NS3100 Multi Depth) or other NMEA instrument. Speed (RMC) can be received via NMEA and displayed by the NS3100 Multi (see section 10-1 for wiring). If an external RMC (speed) input is available from a GPS instrument, then you can set up the NS3100 Multi to use this for speed readings (see section 10-2, step 2); Note: A speed from a paddlewheel sensor is the speed that the boat is moving through the water. A speed from a GPS is the speed over the ground. If there is a current then these two speeds will be different. If a transducer is not fitted to the unit and the corresponding external data is not available then the displayed value will be 0 (for example, when using a GPS input for speed and no speed/ temperature transducer is fitted then temperature displays as 0). 8-2 NavBus NavBus is a Northstar proprietary system. It is high speed and allows a wide range of data to be shared by the instruments. 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 10-2, step 3). 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 instruments are affected. If an alarm sounds, mute it by pressing on any instrument which can display that alarm. For example, mute a depth alarm on any instrument that can display depth. If the unit does not have a depth or a speed/ temperature transducer fitted then the unit will automatically take depth, speed and temperature readings from another instrument, via NavBus, if the data is available. For more information, refer to the NavBus Installation and Operation manual. 16 Northstar NS3100 MULTI 9 NS3100 Multi hardware 9-1 What comes with your NS3100 Multi The NS3100 Multi comes in several configurations.

A fuse. Use a 1 A fuse for between one and five instruments. Optional external beepers or lights can be fitted. The NS3100 Multi 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 8 or your NavBus Installation and Operation Manual). Reference Manual and Installation Manual 17 9-3 Transducers The NS3100 Multi is usually used with a through hull depth transducer and a separate through hull speed/temperature transducer. However, the unit can take readings from another instrument, in which case it may not need transducers (see section 8). Through hull transducers generally give the best performance and are the best choice for displacement hulls. They are mounted in a hole drilled through the bottom of the boat. Plastic through hull transducers are suitable for GRP or metal hulls. Bronze transducers are 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. 9-4 Accessories These accessories are available from your Northstar dealer. 4 m speed transducer extension cable 4 m depth transducer extension cable Through hull speed transducer skin fitting Through hull speed paddlewheel NavBus junction Box (See section 8) 18 Northstar NS3100 MULTI 10 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. The NS3100 Multi can: Send and receive NMEA data from Drive external beepers or lights for the alarm and other instruments. countdown timer. Send and receive data from other Northstar instruments connected via NavBus. Settings for alarms, units, calibration and backlighting are shared (see section 8). 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. 10-1 Installation NS3100 Multi display unit 1 Choose a location for the display unit that is: Easily seen and protected from damage.
