Garmin's GMS 10 Network Port Expander gives you the ability to connect multiple chartplotters and sensors to the Garmin Marine Network.

With this robust 100 Mbit switch, you can connect multiple multifunction displays and sensors to the Garmin Marine Network, taking advantage of Ethernet-like data transfer speeds that are ten times faster than many competing systems.

Plug and play only

The interface between the GMS 10 and the Garmin Marine Network is completely plug-and-play, meaning that any external devices connected to the network are automatically detected and made available. You also have easy access to connect additional devices and displays to the network ports on the GMS 10 using the same standard data cable.

Waterproof connections

The rugged GMS 10 is specifically designed to withstand the harsh marine environment. All connections are 100% waterproof, and unused data ports are sealed with caps to protect the ports from harmful moisture ingress.
