010-00351-00 for GMS 10 Network Port Expander , 100M Ethernet Switch Compatible with Garmin Marine Network Devices , Plug and Play Waterproof Hub for Chartplotters MFDs Sensors

010-00351-00 For GMS 10 Network Port Expander - Scope of applicationThis marine network port expander compatible with Garmin Marine Network is designed as a replacement for Garmin GMS 10 (010-00351-00). It supports expanding marine systems that require connecting more than two devices, including chartplotters, MFDs, and marine sensors. Compatible with Garmin Marine Network devices including GPSMAP 3006C and GPSMAP 3010C.
Complete Installation PackageIncludes essential marine installation components: network port expander (compatible with GMS 10 form factor), marine network cable (320-00227-00 equivalent), 7-pin power cable (320-00023-05 equivalent), and cable grommet (252-00129-00 equivalent). Designed to support clean, secure marine wiring and system integration.
100M Marine Ethernet Switch for High-Speed Data Sharing Equipped with a 100 Mbit marine ethernet switch, this network expander delivers Ethernet-like data transfer speedsup to 10× faster than some competing marine systems. Ideal for real-time sharing of sonar, weather, mapping, radar, and position data across multiple displays.
LED Status IndicatorsThree indicator lights appear above each network port on your Expander: LNK/ACT confirms active connections and data transfer, DUP/COL shows full or half network capacity, and 100 indicates 100 Mbps or 10 Mbps speed. This visual monitoring helps quickly diagnose network performance and ensures stable operation of your marine Ethernet network.
Marine-Grade Electrical SpecsDesigned for real marine environments with 1035 VDC input, 2.75W max power consumption, and AGC/3AG 2.0A fuse. Operating temperature range from -15°C to 70°C (5°F158°F) ensures stable performance on boats and yachts.
Connect Multiple Chartplotters, MFDs & Marine SensorsThis marine network port expander solves the common limitation of insufficient network ports when adding equipment. Easily connect multiple chartplotters, multifunction displays (MFDs), radar units, sonar modules, and satellite weather/audio receivers into one unified marine network.
IPX7 Waterproof HousingEngineered as a waterproof marine ethernet switch, featuring sealed ports and a fully gasketed enclosure. Rated IPX7, protecting against salt spray, moisture, and harsh marine conditions.
