Overview

The Garmin 010-12531-00 is a cable coupler that joins two Garmin Marine Network cables that use the small connector, letting you extend a network run without pulling a new cable.

It is a female-to-female inline coupler with threaded ends that match the locking collars on small-connector Garmin network cables, helping the connection stay tight in a helm, hardtop, or electronics locker where vibration is normal.

Use it when a cable comes up short after routing through a tower, rigging tube, or conduit, or when you want a service loop near networked gear like chartplotters, sonar modules, radar, or a network switch.

Key features

• Joins two Garmin Marine Network cables that use the small connector
• Also used to join Garmin BlueNet network cables that share the same small connector style
• Female-to-female coupler for connecting two standard network cables end-to-end
• Threaded ends mate with the cable collars to help prevent loosening from vibration

Compatibility and fit

This coupler matches the small Garmin network connector. It will not mate with older large-connector Garmin Marine Network cables, and it is not an adapter for NMEA 2000 or NMEA 0183 wiring.

Plan the coupling point where you can reach it later. Being able to hand-tighten the collars fully and inspect the joint during routine service helps avoid intermittent network dropouts.

Installation and setup

Power down the connected electronics, route both network cables to the same location, then thread each cable collar onto the coupler until it is snug. Keep bends gentle right at the connectors and add strain relief so the coupler is not carrying the weight of a long cable run.

Use on board

This is a good match for boats with Garmin network gear split between the helm and a hardtop, tower, or equipment bay where cable routing is already finished and you need a clean way to bridge a missing length.
