Apply marine sealant between the mounting surface and the 

device to properly seal and prevent leakage behind the 

dashboard.

21

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

marine sealant around the cutout.

22

Place the device into the cutout.

23

Secure the device to the mounting surface using the larger 

machine screws   or the included wood screws.

24

Wipe away all excess marine sealant.

25

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.

Connecting to Power

 WARNING

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.

You should connect the red wire to the same battery through the 

ignition or another manual switch to turn the device on and off.

1

Route the power cable between the power source and the 

device.

2

Connect the red power wire to the ignition or another manual 

switch, and connect the switch to the positive (+) battery 

terminal if necessary.

3

Connect the black wire to the negative (-) battery terminal or 

to ground.

4

Connect the power cable to the device, and turn the locking 

ring clockwise to tighten it.

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.

Additional Grounding Consideration

This device should not need additional chassis grounding in 

most installation situations. If you experience interference, you 

can use the grounding screw on the housing to connect the 

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

interference.

Garmin Marine Network Considerations

NOTICE

A Garmin Marine Network PoE Isolation Coupler 

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

device, such as a FLIR

®

 camera, to a Garmin Marine Network. 

Connecting a Power over Ethernet (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. If multiple power sources are 

used for Garmin Marine Network devices, you must tie all 

ground connections from all power supplies together using a 

low resistance connection or tie them to a common ground 

bus bar, if available.

• 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 NETWORK ports on the device each act as a network 

switch. Any compatible device can be connected to any 

NETWORK port to share data with all devices on the boat 

connected by a Garmin Marine Network cable.

NMEA 2000

®

 Considerations

NOTICE

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.
A NMEA 2000 Power Isolator (010-11580-00) should be used in 

installations where the existing NMEA 2000 network 

manufacturer is unknown.
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.
