GMS 10 Network Port Expander

The GMS 10 network port expander allows you to connect multiple chartplotters and sensors over the Garmin Marine Network. With this robust 100 MB switch, you can connect multiple multi-functional displays (MFDs) and sensors to the marine network and gain the benefit of Ethernet-like data transfer speeds up to 10 times faster than some competitive systems.

Just Plug-and-Play

The GMS 10 and the Garmin Marine Network are completely plug-and-play, which means all peripherals are automatically detected and readily accessible once they’re connected to the network. Likewise, you easily can expand your system using the same standard data cable to plug additional units and displays into the GMS 10 network ports.

Seal Your Connections

The rugged GMS 10 is specifically designed to withstand the corrosive marine environment. All connections are totally water resistant, and sealed covers keep harmful moisture away from unused data ports.
