1 Introduction

The MULTI 3100 measures and displays speed, water depth and water temperature. It can calculate and display average speed, maximum speed, trim speed, trip log (distance) and total log. An installed MULTI 3100 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 boats power supply. The MULTI 3100 is part of the NAVMAN 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. 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. Do not use a high pressure water blast on the speed transducer paddlewheel as it may damage the bearings.
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.

3-5 Set speed damping
Waves and wind cause the boat speed to fluctuate slightly. To give a stable reading, the MULTI 3100 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.
Press or to change the resolution setting to 0.0 or 0.00. Press.

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 + several times until the Speed Press Calibration screen is displayed (after this, it does not matter if the boat speed changes):
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. At the end, note the trip log distance (see section 4). + several times until the Log Press Calibration screen is displayed:

3 Press or to change the displayed speed to the measured boat speed. Press.

4 Log and total log

The MULTI 3100 has two distance logs: LOG: Trip distance. The distance travelled since log was reset. 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).

4-1 Reset log

Resetting zeros the log (trip distance): Press Press until LOG is displayed. +.

4-2 Reset total log

Total log Resetting zeros the total log (total distance), as well as the log and avg speed: 1 2

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 Keel offset Water surface Depth of transducer Transducer Note: The boat illustrated uses a through hull transducer Keel offset Positive value Negative value will display the depth from the surface to the bottom of the water. 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.

MULTI 3100 Installation and Operation Manual 11
8 Systems of several instruments
Several NAVMAN instruments can be connected together during installation to share data. There are two ways of connecting instruments together, NavBus or NMEA.

8-2 NavBus

NavBus is a NAVMAN 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.

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 NAVMAN (eg REPEAT 3100) or other NMEA instrument. Speed (RMC) can be received via NMEA and displayed by the MULTI 3100 (see section 10-1 for wiring). If an external RMC (speed) input is available from a GPS instrument, then you can set up the MULTI 3100 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).

9 MULTI 3100 hardware

9-1 What comes with your MULTI 3100
The MULTI 3100 comes in several configurations. Standalone configuration MULTI 3100 unit with protective cover. Warranty card. Mounting template. This Installation and Operation Manual. In addition, the standalone configuration usually requires a depth transducer and a speed/temperature transducer (see section 9-3). Kit configuration The MULTI 3100 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. Through hull speed/temperature transducer. Transducer Installation Manual.

9-2 Other parts required

One or more 3100 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. Optional external beepers or lights can be fitted. The MULTI 3100 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).

9-3 Transducers

The MULTI 3100 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 NAVMAN through hull transducers are available, plus in hull and transom mount transducers. For more information, refer to the Transducer Installation manual or consult your NAVMAN dealer.

9-4 Accessories

These accessories are available from your NAVMAN dealer.
4 m speed transducer extension cable
4 m depth transducer extension cable

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 MULTI 3100 can: Drive external beepers or lights for the alarm and countdown timer. Send and receive data from other NAVMAN instruments connected via NavBus. Settings for alarms, units, calibration and backlighting are shared (see section 8). Send and receive NMEA data from other instruments. 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 NAVMAN dealer. Plastic through hull transducers are usually unsuitable for wood hulls. If in doubt, consult a marine surveyor or marine engineer. Ensure that any holes that you cut will not weaken the boats structure. If in doubt, consult a qualified boat builder.
