Section 2: Installation
Preparation
When installed, the gauge will cover an area on the dash 2-3/8" (60.3
mm) in diameter. To mount the unit, first make sure there is at least 23/4" (70 mm) from the front of the dash to any obstruction behind the
dash. The maximum usable dash thickness is 1-1/8" (28.5 mm). Also, be
sure there is room to route the network and buzzer cables. The
following figure shows gauge dimensions.

Caution:
You should read over the entire installation section before
drilling any holes in your vessel!
Recommended Tools and Supplies
Recommended tools for this job include: hole saw, 2 1/8" (54 mm) hole
saw bit, drill, 1/8" (3 mm) drill bit (for starter hole).
Other supplies are not included, unless otherwise indicated. If you need
to route the gauge's network cable connector through a bulkhead, you
will need a drill and a 3/4" drill bit.
If the dash does not have a standard 2-1/8" (54 mm) hole, you will need
a drill or saw to make the hole. Carefully measure the dash thickness
and the hole area before cutting or drilling.
3
The buzzer installation requires two cable ties and two wire nuts or
other wire connectors.
If you need to extend any of the buzzer or dash light wires, use a
minimum of 24 gauge wire and wire connectors of your choice. Wire
nuts or electrical tape are required to cap any unused bare wires.
Installation Sequence
You can install this gauge in some other order if you prefer, but we
recommend the installation sequence summarized 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 (piezo) and its wire
route.
4. If you want to turn on the gauge's backlight whenever you turn on
your dashboard lights, 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 2-1/8" (54 mm) hole in the dash. If no
2-1/8" (54 mm) hole in the dash, use a hole saw to cut a mounting hole.
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
When you determine the location for the LMF-200, drill a 2-1/8" (54
mm) hole in the dash or use an existing gauge hole. Slide the unit's
cables through the hole from the front side of the dash. Push the LMF200 housing through the hole until it is flush with the dash surface.
Make sure the face of the gauge is aligned correctly.
Next, slide the rubber gasket and plastic-mounting collar over the
cables and onto the back side of the gauge.
4
Insert gauge through the hole in the front side of the dash (left). Slide
the rubber gasket over the cables, followed by the plastic collar (right).
Slide the gasket forward so it is flush with the back of the dash, then
screw on the mounting collar, turning it until it is snug against the
gasket and the back of the dash.
Find a buzzer location that is protected from the elements, but that
still allows you hear it. Connect the buzzer wires according to one of
the two wiring diagrams on the following page.
NOTE:
Later model LMF-200 gauges have different color wires, so examine
the wiring diagrams carefully before connecting any wires.
Use two cable ties and attach the buzzer to one or both of the cables at
the back of the gauge or use the adhesive back of the buzzer to stick it
to a flat, clean surface.
If desired, connect the dash light wires as shown in the following
figure. Finish the installation by plugging the network cable into the
network.
Wiring
The LMF-200 draws operating power from the NMEA 2000 network.
The gauge does not have an on/off switch — whenever the network has
power, the LMF-200 is on and drawing current.

Ideally, the NMEA 2000 network itself is powered from a switch on the
boat's accessory panel, allowing network power to be turned on and off.
To automatically turn on the gauge backlights when you turn on your
other dashboard lights, connect the red dash light wire to the positive
side of the switch controlling the dash lights and connect the black
dash light wire to ground
NOTE:
If multiple gauges are connected to the same NMEA 2000 bus, only
one gauge has to be connected to the dashboard lights for all gauge
6
backlights to come on when the dashboard lights are turned on.
The gauge connected to the dashboard lights will send a signal
across the network, causing the other gauges to turn on their
backlights.
Caution:
The bare ends on any unused wires could cause an electrical
short if left exposed. To prevent this, you should cover the
individual wire ends — either by capping them with wire nuts
or wrapping them with electrical tape. (You should cut off the
bare wire before taping off the ends.)
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.
7
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 in Section 3: Operation.

Boat Setup
When the LMF-200 is turned on the first time the Boat Setup menu
will appear on the screen. You will not be able to proceed without
completing boat setup. If, however, you have
one or more of the following devices — Suzuki
Engine Interface, EP-10 Fuel Flow, EP-15
Fluid Level, EP-45 Pressure Sensor or an EP50 Storage Device — already configured in the
network with the same engine-tank
configuration, you WILL NOT have to go
through boat setup when adding a new gauge
to the network. After adding the gauge to the network, the Boat Setup
menu will be cleared from the screen and the unit will begin normal
operation in 1-2 seconds. If you have more than one gauge on the
network, you will only have to execute Boat Setup for one of the
gauges. When the data is input, it is transmitted over the network and
saved to other units.
NOTE:
If you add an EP-10 Fuel Flow, EP-15 Fluid Level, EP-45 Water
