Preparing the Network Cable

1

Cleanly cut the Ethernet cable

À

to the needed length.

NOTE:

Retain the connector for use in step 4.

2

Remove the strain-relief nut

Á

from the cable-connection

housing

Â

and slide the nut onto the cut end of the Ethernet

cable.

3

Feed the cut cable end through the connection housing.

4

Examine the connector removed from the cable and

compare it to this table to determine whether cable side A or

cable side B was removed.

NOTE:

The Garmin Marine Network requires cross-over

cables not exceeding 100 m between devices.

5

Using a sharp knife, insert the blade between the cable

shield and jacket, and slit the jacket 16 mm (

5

/

8

in.) from the

cut end of the cable.

6

Peel the jacket back and remove the slit portion.

7

Trim the drain wire

Ã

to approximately 14 mm (

9

/

16

in.) and

fold the drain wire back over the jacket.

8

Arrange the individual wires in order according to table

shown in step 4.

NOTE:

When constructing a custom cable from bulk wire,

you must create both a side A and a side B.

9

Trim the wires to an even length, leaving approximately

14 mm (

9

/

16

in.) from the ends of the wires to the jacket edge.

10

Wrap the supplied copper tape around the drain wire and

jacket.

11

Using a pair of pliers, squeeze the copper tape to pre-form

the cable jacket end.

Installing the Network Connector

1

With the wires in the correct order, insert the wires into the

modular plug until the ends of the wires touch the bottom of

the plug.

2

Verify the wires are in the correct order.

3

If any wire is not in the correct position, remove the plug,

arrange the wires in the correct order, and reinsert the wires

into the plug.

4

Using a modular plug hand tool, crimp the plug onto the

wires.

5

Align the release tab on the modular plug with the

corresponding notch in the cable-connection housing, and

push the cable through the connection housing until plug is

securely seated.

6

Screw the strain relief nut onto the cable-connection housing

and tighten with a 15 mm wrench.

NOTE:

Do not overtighten the nut.

7

Install the O-ring onto the housing.

The cable is now ready for use.
