The Garmin GMS 10 Network Port Expander is designed to expand a compatible Garmin Marine Network, allowing multiple chartplotters, multifunction displays, and marine network devices to share information through a centralized connection point. Its 100 MB network switching capability helps create a more flexible onboard electronics setup while maintaining fast data communication between connected equipment.

Garmin GMS 10 Network Port Expander - Description

Built for marine use, the GMS 10 offers plug-and-play operation that automatically detects connected compatible devices. The sealed network connections are designed to resist moisture and the harsh conditions commonly encountered aboard boats, while the compact unit provides a practical way to expand an existing Garmin marine electronics network.

1. Expand Your Garmin Marine Network

The GMS 10 provides additional network connectivity for compatible Garmin marine electronics. It allows multiple chartplotters, displays, and sensors to communicate through the same onboard network.

2. High-Speed 100 MB Network Switching

The integrated 100 MB switch provides fast data transfer between compatible networked devices. This helps connected equipment share important information such as mapping, weather, sounder, and position data.

3. Plug-and-Play Operation

The GMS 10 is designed for straightforward installation and automatic device detection. Once compatible peripherals are connected, they can be recognized and accessed through the Garmin Marine Network.

4. Flexible System Expansion

As your onboard electronics system grows, the GMS 10 makes it easier to add additional compatible displays and devices. Standard Garmin marine network cables can be used to connect supported equipment to available network ports.

5. Marine-Ready Construction

The network expander is built with a rugged, gasketed housing designed for use in marine environments. Its sealed connections help protect network ports from moisture and water exposure.
