Section 1: Introduction

Thank you for buying the Lowrance® LMF-400! Your unit is a high­quality, multi-function, digital gauge designed to work with a
LowranceNET™ network. This is the NMEA 2000
developed by Lowrance Electronics.

Caution:

Installing LowranceNET NMEA 2000 devices is significantly
different from installing earlier Lowrance components without

NMEA 2000 features. You should read all of the installation
instructions before proceeding.

This gauge will only work with a NMEA 2000 network. It MUST be
connected to a NMEA 2000 network or it WILL NOT function. When
properly installed, the LMF-400 will display information from a variety
of Lowrance Electronic Probe (EP) sensors and other NMEA 2000
devices connected to the network.

®

networking system

A NMEA 2000 network using LowranceNET components.

All Lowrance NMEA 2000 capable devices are either NMEA 2000
certified or certification is pending. See our web site,
for the latest product information.

To get started with your Lowrance gauge, read Section 2: Installation.
After you have read those instructions, install the gauge and any EP
sensors you may have purchased, then read the rest of this manual.
Each sensor comes with its own installation instruction sheet, but this

Section 2: Installation

Preparation

The design of the LMF-400 allows convenient mounting in the dash of
your boat, or it can be mounted on any flat panel at least four inches in
diameter.

To mount the LMF-400 in the dash, first make sure there is sufficient
clearance behind the panel in the desired location. At least 3-1/2 inches are
needed behind the surface of the dash to clear all connectors and wiring.

Recommended Tools and supplies

Recommended tools for this job include: hole saw, 3/38" (86 mm) hole
saw bit, drill, 1/8" (3 mm) drill bit (for starter hole). Required supplies
for this job include: "U" bracket, lock washers and wing nuts (included).

Installation Sequence

You can install this gauge in some other order if you prefer, but we
recommend the installation sequence listed below.

1. Determine the location for the gauge so you can plan how and where
to route the cables. This will help you make sure you have enough cable
length for the desired configuration.

2. Determine the location of the nearest device on the boat's NMEA
2000 network, along with the route of the gauge's network cable.

3. Determine the location for the alarm buzzer and its wire route.

4. If you want the gauge's backlight to turn on when the dashboard
lights are turned on, locate your boat's dash light switch and determine
how to route the gauge's dash light wires to it.

5. Install the gauge in a standard 3-3/8 inch (86 mm) hole in the dash.
If no 3-3/8 hole available in the dash, you will have to drill a 1/8" pilot
hole, then use a hole saw to cut a mounting hole. See instructions for
Mounting the Unit below.

6. Connect the buzzer wires and install the buzzer. If desired, connect
the dash light wires to the boat's dash light switch.

7. Connect the network cable to the NMEA 2000 network.

Mounting the Gauge

If no standard mounting hole is available in the dash, drill a 1/8" pilot
hole, then cut a 3-3/8 inch (86 mm) diameter mounting hole with a hole
saw. A "U" bracket is supplied to hold the unit to the dash. Place it over
the threaded studs on the back of the unit and secure it with the lock
washers and nylon wing nuts provided with the unit.

3

Y

Secure unit to the dash using "U" bracket as shown.

The bracket is designed to secure the unit to a dash with a thickness of
2 mm. If your dash is thicker than 2 mm, the "U" bracket will be too
long. Simply place washers or spacers between the unit and the bracket
until you can tighten the wing nuts and secure the unit in place. You
are now ready to wire the unit to the buzzer (piezo) and dash lights.

Connecting the LMF-400 to the buzzer (piezo), will enable the buzzer to
sound when buttons are pressed and when alarms and level warnings
are triggered. Wiring the unit to the boat's dash lights, will turn on the
LMF-400 backlight when the dash lights are turned on.

4

If you do not want to use the buzzer or dash light wires, clip the bare
ends off the wires, then cap them with wire nuts or electrical tape.

To wire unit to the buzzer (piezo):

1. Connect the LMF-400 yellow wire to the buzzer (piezo) ground wire.

2. Attach the LMF-400 blue wire to the buzzer (piezo) positive wire.

3. Select a buzzer location that is protected from the elements, but will
still allow you to hear it. Use the adhesive back on the buzzer to mount
the buzzer to a flat, clean surface.

To wire unit to dash lights:

1. Connect the LMF-400 black wire to the dash light ground wire.

2. Now attach the LMF-400 white wire to the dash light positive wire.

Connecting to a NMEA 2000 Network

A network bus is an installed and operational network cable (backbone)
running the length of your boat, already connected to a power supply
and properly terminated. It provides network connection nodes at
various locations around your boat.

Compatibility

You will easily be able to connect your unit to both red (DeviceNet) and
blue connector networks, regardless of whether your unit has a blue or
red connector network cable. Check the adapter cable segment in the
Setup and Installation of NMEA 2000 Networks, General Information"
that came packed with your unit. If you do not have that document, it
can be downloaded free from the Lowrance web site.

LowranceNET Node Kit for a NMEA 2000 network. Includes a 2 foot

extension cable, T connector, 120-ohm male terminator and 120-ohm

female terminator.

Network Backbone and Network Nodes

A network bus backbone consists of network cabling, terminators and T
connectors. Network nodes are made by fitting T-shaped connectors into
the backbone (using the sockets on the sides) and attaching any network
device to the bottom of the T.

5

Adding a Network Node

You can add a node to any existing connection, anywhere along the
network backbone. This connection could be between a T connector and a
terminator, between two T connectors, between a T connector and a
backbone extension cable or between two extension cables. Wherever you
want to add the new node, separate the sockets of the existing connection
and install the T connector between them.

NOTE:

If you add an EP-10 Fuel Flow, EP-15 Fluid Level, EP-45 Water
Pressure or EP-50 Storage Device sensor to the network, you must
go through Boat Setup so the engine-tank configuration will be
consistent among the sensors in the LowranceNet. Follow the Boat
Setup procedure included in Section 3: Operation.

Additional NMEA information

For more detailed information about setting up a NMEA 2000 network,
refer to the "Setup and Installation of NMEA 2000 Networks, General
Information" that came with your unit. If you do not have that
document, it can be downloaded free from the Lowrance web site.

Calibrating EP Sensors

The factory calibration settings for the EP-10 Fuel Flow, EP-15 Fluid
Level and Suzuki Engine Interface should be adequate for the majority
of applications, so calibration will not be necessary in most cases.

The default calibration for the EP-15 Fluid Level is just as accurate as

51

standard fluid level gauges. If, however, the tank has an irregular
shape or greater accuracy is needed, calibration is recommended.

The default calibration for the EP-10 Fuel Flow and Suzuki Engine
Interface are adequate in most cases, but if Fuel Used readings are off
by more than 3 percent, calibration is recommended.

Calibrating EP-10 Fuel Flow

The default calibration for an EP-10 Fuel Flow is adequate in most
cases, but if fuel used readings are off by more than 3 percent,
calibration is recommended.

Fuel Flow Accuracy

To check fuel flow accuracy, add the Fuel Manager page or any of the
digital gauge pages to the page screen rotation, then customize the
selected page with Fuel Used data. To see instructions on how to Add
Pages and Customize Pages, refer to the Operation Section.

NOTE:

Make sure the fuel flow has been set as the Fuel Remaining Source,
otherwise, you will not be able to calibrate the fuel flow. See Fuel
Remaining Source instructions on page 28.

After filling up your tank, take your vessel out on the water and burn
at least five gallons of fuel. Be sure you run only ONE engine —
the engine attached to your fuel flow.
Fill up your tank again, noting how much fuel you added to the tank.
Compare that number to the Fuel Used figure displayed on the page
you customized. If the amount of fuel you added to the tank and the
fuel used figure are off by more than 3 percent, we recommend the fuel
flow be calibrated.

NOTE:

You must use the gauge's Refill Tank command when filling your
fuel tank to keep the fuel flow updated with correct information on
the amount of fuel in the tank.

Refill Tank

You must use the Refill Tank command every time you fill up and
every time you calibrate a fuel flow to make sure the fuel flow reads the
tank as full. For more information on the Refill Tank function see page

26.

2-Point Calibration

A 2-point calibration is best suited for rectangular or square-shaped
tanks, where the capacity of the top half of the tank matches the
capacity in the lower half of the tank. In a two-point calibration, you
will set two points, one each for empty and full levels. You can begin
calibration at either of the two points, but we recommend starting with
an empty tank. You will fill the tank to complete calibration.

NOTE:

You DO NOT have to calibrate both points to complete the
calibration and you can calibrate the points (Empty Level and Full
Level) in any order you wish. Remember: Points that are not

calibrated will not be as accurate as points that have been
calibrated. For the greatest accuracy, we recommend both points be

calibrated.

process, but we recommend starting calibration with an empty tank. In
a 3-point calibration, you will set three points, one each for empty, half
and full levels.

NOTE:

You DO NOT have to calibrate all three points to complete the
calibration and you can calibrate the points (Empty Level, Half

5-point calibration is best suited tanks that vary greatly in shape from
top to bottom. You can begin calibration at any point in the 5-point
calibration process. We recommend starting calibration with an empty
tank. In a five-point calibration there are five calibration points: Empty
Level, 1 Qtr Level, Half Level, 3 Qtr Level and Full Level.

NOTE:

You DO NOT have to calibrate all five points to complete the
calibration and you can calibrate the points (Empty Level, 1
Quarter Level, Half Level, 3 Quarter Level and Full Level) in any
order you wish. Remember: Points that are not calibrated will not be
as accurate as points that have been calibrated. For the greatest
accuracy, we recommend all five points be calibrated.

NOTE:

If you have calibrated your fluid level sensor and are having
problems with the sensor's performance, be sure to check the
sending unit. You can do this by using an ohm meter to test the
resistance of the unit. Connect the sending unit hot wire (usually
pink) and the ship or sending unit ground wire (usually black) to
the ohm meter. With the tank full, the resistance should be around
33-1/2 ohms. When the tank is the empty, the resistance should be
around 240 ohms. If, when the tank is full or empty, the ohm
readings are significantly different from the standard full (33-1/2)
and empty (240) ohms levels, there is a problem with the sending
unit. If the ohm readings are the same in both cases, the sending
unit is stuck.

must first receive a return authorization number from Customer
Service. Products shipped without a return authorization will not be
accepted. When shipping, we recommend you do the following:

1. Please do not ship the knobs or mounting bracket with your unit.

2. If you are sending a check for repair, please place your check in an

envelope and tape it to the unit.

3. For proper testing, include a brief note with the product describing
the problem. Be sure to include your name, return shipping address
and a daytime telephone number. An e-mail address is optional but
useful.

4. Pack the unit in a suitable size box with packing material to prevent
any damage during shipping.

5. Write the Return Authorization (RA) number on the outside of the
box underneath your return address.

6. For your security, you may want to insure the package through your
shipping courier. Lowrance does not assume responsibility for goods
lost or damaged in transit.
