Installing the Power and Network Cables

Route the cable as needed, based on the type of mount you are using.
When installing the power and network cables, consider the following:
• To ensure safety, use the appropriate tie-wraps, fasteners, and sealant to secure the cable along a route and through any bulkhead or deck.
Avoid running the cable near moving objects, high-heat sources, or through doorways and bilges.
• Avoid installing the cable next to or parallel to other cables, such as radio antenna lines or power cables. This is essential to avoid
interference to or from other equipment. If this is not possible, shield the cable with metal conduit or a form of EMI shielding.
• You may need to drill a 1
cable installation hole.
◦ The grommet does NOT provide a waterproof seal. To waterproof the grommet, apply a marine sealant.
◦ You can purchase additional cable grommets through Garmin or a Garmin dealer.
• Use the optional field-installable RJ-45 network connector (included) to create a custom-length Garmin Marine Network cable if needed
(see page 9).
To install the cable assembly:
1. Align the notch and locking ring on the power cable to the power connector. Press the 2-pin
power cable to the power connector. Tighten the power-cable locking ring clockwise until it is
firmly sealed..
2. Press the RJ-45 marine network cable to the RJ-45 socket. Tighten the RJ-45 locking ring
clockwise until it is firmly sealed.
3. Route the power and network cables through the front of the radar (Figure 7), or through a
hole drilled through the mounting surface (Figure 8). Avoid excessively bending or twisting the
cables.
4. Install the hatch on the front of the radar.
