Apply marine sealant between the mounting surface and the

device to properly seal and prevent leakage behind the

dashboard.

If you will have access to the back of the device, apply

marine sealant around the cutout.

Place the device into the cutout.

Secure the device to the mounting surface using the larger

machine screws

or the included wood screws.

Wipe away all excess marine sealant.

Install the trim caps by snapping them in place around the

edges of the device.

Cable and Connection Considerations

• The cables may have been packaged without the locking

rings installed. If so, you should route the cables before you

install the locking rings.

• After connecting a locking ring to a cable, make sure the ring

is securely connected and the O-ring is in place so the

connection remains secure.

Power/NMEA

0183 Cable

• The wiring harness connects the device to power, NMEA

0183 devices, and a lamp or a horn for visible or audible

alerts.

• If it is necessary to extend the NMEA 0183 or alarm wires,

you must use 22 AWG (.33 mm²) wire.

• This cable provides one differential NMEA 0183 input and

output port.

Connecting the Wiring Harness to Power

When connecting the power cable, do not remove the in-line

fuse holder. To prevent the possibility of injury or product

damage caused by fire or overheating, the appropriate fuse

must be in place as indicated in the product specifications. In

addition, connecting the power cable without the appropriate

fuse in place voids the product warranty.

Route the wiring harness to the power source and to the

device.

Connect the red wire to the positive (+) battery terminal, and

connect the black wire to the negative (-) battery terminal.

If necessary, install the locking ring and O-ring on the end of

the wiring harness.

Insert the cable into the POWER connector on the back of

the device, pushing firmly.

WARNING

Turn the locking ring clockwise to attach the cable to the

device.

Additional Grounding Consideration

This consideration is applicable only to devices that have a

grounding screw. Not all models have a grounding screw.

This device should not need additional chassis grounding in

most installation situations. If you experience interference, the

grounding screw on the housing can be used to connect the

device to the water ground of the boat to help avoid the

interference.

Garmin Marine Network Considerations

A Garmin Power over Ethernet (PoE) Isolation Coupler (P/N

010-10580-10) must be used when connecting any third-party

device, such as a FLIR

camera, to a Garmin Marine Network.

Connecting a PoE device directly to a Garmin Marine Network

chartplotter damages the Garmin chartplotter and may damage

the PoE device. Connecting any third-party device directly to a

Garmin Marine Network chartplotter will cause abnormal

behavior on the Garmin devices, including the devices not

properly turning off or the software becoming inoperable.

This device can connect to additional Garmin Marine Network

devices to share data such as radar, sonar, and detailed

mapping. When connecting Garmin Marine Network devices to

this device, observe these considerations.

• All devices connected to the Garmin Marine Network must be

connected to the same ground.

• A Garmin Marine Network cable must be used for all Garmin

Marine Network connections.

◦ Third-party CAT5 cable and RJ45 connectors must not be

used for Garmin Marine Network connections.

◦ Additional Garmin Marine Network cables and connectors

are available from your Garmin dealer.

• The ETHERNET ports on the device each act as a network

switch. Any compatible device can be connected to any

ETHERNET port to share data with all devices on the boat

connected by a Garmin Marine Network cable.

NMEA 2000

Considerations

If you are connecting to an existing NMEA 2000 network,

identify the NMEA 2000 power cable. Only one NMEA 2000

power cable is required for the NMEA 2000 network to operate

properly.

If you are connecting this device to an existing NMEA 2000

network or engine network by another manufacturer, you should

install a NMEA 2000 Power Isolator (010-11580-00) between

the existing network and the Garmin devices.

If you are installing a NMEA 2000 power cable, you must

connect it to the boat ignition switch or through another in-line

switch. NMEA 2000 devices will drain your battery if the NMEA

2000 power cable is connected to the battery directly.

This device can connect to a NMEA 2000 network on your boat

to share data from NMEA 2000 compatible devices such as a

GPS antenna or a VHF radio. The included NMEA 2000 cables

and connectors allow you to connect the device to your existing
