Installing the Field-Installable RJ-45 Network Connector (Optional)

A field-installable RJ-45 network connector is provided for you to create a network cable that is the correct length for your installation.
➊ O-Ring
➋
RJ-45 modular plug
➌ Ethernet cable termination
C opper tape strip (not shown)
Preparing the Network Cable
1. Cleanly cut your Ethernet cable to the desired length. Retain the cut RJ-45 connector for Step 4.
2. Remove the strain-relief nut from the cable-connection housing and slide it onto the cut end of the cable as shown.
3. Feed the cut cable end through the connection housing as shown.
4. Examine the RJ-45 connector removed in Step 1 and compare it to the wire positions in the table below. Note which cable side, A or B, was
removed in Step 1.

nOTe: The Garmin Marine Network requires cross-over cables not exceeding 100 meters between devices. When constructing a custom cable
from bulk wire, you must create both a Side A and Side B.
5. Prepare the cable for plug installation:
• Using a sharp knife, insert the blade between the cable shield and jacket. Slit the jacket
trimmed end of the cable.
• Peel the jacket back and remove the slit portion.
• Trim the shield and Mylar film away from wires. Be careful not to cut any of the wires.
• Fold the drain wire back over the jacket and trim to approximately
• Untwist the wire pairs enough to ensure a proper connection.
• Arrange individual wires in proper order according to the table shown above. For example, if you have identified
the end of the cable in Step 4 as Side A, arrange the wires for Side A. If you are constructing a custom cable
from bulk wire, you need to make both a Side A and a Side B connection.
• Trim the wire ends to an even length, leaving approximately
• Place the drain wire on the jacket. Wrap the supplied copper tape around cable as close to the edge of the jacket as possible.
• Using a pair of pliers, squeeze the copper tape to pre-form the cable jacket end for easier insertion into the plug. Use caution to avoid
damaging the copper tape.
