MULTI 3100 Installation and Operation Manual
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 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.
The display unit.
How the transducer measures speed
Depth and speed / temperature transducers
which are attached to the hull and wired to the
display unit.
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.
The unit is powered from the boat’s 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.
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.
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.

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
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.
Simulate mode allows you to become familiar with
the unit off the water. In Simulate mode, the MULTI
3100 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.

3 Speed, average speed, maximum speed, trim speed
The unit can display several speeds:
A higher value averages readings over a longer
period of time. This gives the most stable speed
but will ignore some true speed changes.
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:
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:
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.
Damping
equals 3
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):

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.

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.
NAVMAN
MULTI 3100 Installation and Operation Manual
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).
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.

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:
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.
A positive keel offset displays depth as
measured from a point above 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.
For example, if you set the offset as the
distance from the transducer to the surface, it

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
8-1 NMEA
When instruments are connected by NavBus:
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).
NavBus is a NAVMAN proprietary system. It is high
speed and allows a wide range of data to be shared
by the instruments.
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.
9 MULTI 3100 hardware
9-1 What comes with your MULTI 3100
9-2 Other parts required
The MULTI 3100 comes in several configurations.
One or more 3100 series instruments will be
connected to the boat 12 V power supply via:
Standalone configuration

Warranty card.
Mounting template.
This Installation and Operation Manual.
An accessory switch to turn the instruments on
and off.
A fuse. Use a 1 A fuse for between one and five
instruments.
In addition, the standalone configuration usually requires
a depth transducer and a speed/temperature transducer
(see section 9-3).
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.
Kit configuration
The MULTI 3100 is available in several kit configurations

NAVMAN
MULTI 3100 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.

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.
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.
NAVMAN
MULTI 3100 Installation and Operation Manual
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 boat’s structure. If in doubt, consult a qualified
boat builder.

At least 100 mm (4") from a compass and
at least 500 mm (19.5") from a radio or
radar antenna.
13
Away from engines, fluorescent lights,
power inverters and radio or radar
transmitters.
Accessable from behind; the minimum
clearance required at the back is 50 mm
(2") (see mounting diagram).
With the back of the unit protected from
moisture.
2 The unit must mount on a flat panel which is
less than 20 mm (0.75") thick. Stick the
mounting template in place. Drill a 50 mm (2")
fixing hole through the centre hole in the
template. Note that the template allows space
around the unit for the protective cover.
3 Remove the fixing nut from the back of the unit.
Insert the stud at the back of the unit through
the mounting hole. Hand tighten the fixing nut.
Transducers
1 If the MULTI 3100 does not come with
transducers, choose suitable transducers (see
section 9-3). If the MULTI 3100 is supplied with
transducers, see section 9-3 to ensure that
they are suitable.
2 Choose suitable locations for the transducers
and install them by following the instructions in
the Transducer Installation manual.
3 Fit the cables between the transducers and the
display unit:
Keep the cable away from other cables,
engines, fluorescent lights, power inverters
and radio or radar transmitters.
Do not lay the cable in the bilge.
If necessary, extend the cable by adding
extension cables.
Do not cut the cable on any depth
transducer.
Secure the cable at regular intervals.
4 Connect the transducers to the display unit
connectors.
Power/data wiring
1 Wire the display unit power/data cable:
The unit requires 12 V DC power. Fit a
power switch and fuse to the power supply
or power the unit from a fused auxiliary
switch. The fuse should be 1 A for up to
five instruments.
If the external beepers and lights require
more than 250 mA DC total, fit a relay.
A single unit can be wired as shown below:
