11GPSMAP 3006C/3010C & GPS 17INSTALLATION INSTRUCTIONSGarmin Marine NetworkThe Garmin Marine Network is a waterproof Ethernet-based system that allows Multi-Function Displays (MFD) to communicate with sensorsand other MFDs over the network. Waterproof RJ-45 connections allow for simple installation and high-speed connectivity. For a simpleinstallation with one MFD and one sensor, the two devices can be directly connected with a Garmin Marine Network cable. If more than twoMFDs are installed, you need a Garmin Marine Network Port Expander (GMS 10) to expand the network. If two or moreGPSMAP 3005C/3006C/3010C units are installed and networked, only one GPS 17 antenna needs to be installed. You can add up to five totaldevices to the Network Port Expander. If more than five are needed, you can add more Network Port Expanders to the network. This networkis NOT compatible with PC networks. Do NOT attach PC devices to the Garmin Marine Network. Some examples of the Garmin MarineNetwork are included below. Refer to the individual installation instructions for the individual sensors. Additional Garmin Network cables areavailable from your Garmin dealer or direct from Garmin.NOTE: Power connections for network components are not shown in the following illustrations.GARMINGPSMAP 3006C/3010CMFDGARMIN GDL 30/30AMARINE WEATHER/AUDIOSATELLITE RECEIVERGPS 17GARMIN GMS 10MARINE NETWORK PORT EXPANDERTO TRANSDUCERGSD 20 or GSD 21SOUNDERMODULEGARMINMARINE RADARGARMINGPSMAP 3005CMFDxxx xxxxx xxxxxxxxxxxxxxxxxxxGARMINGPSMAP 3006C/3010CMFDGPS 17GARMINGPSMAP 3005CMFDTwo MFD NetworkTwo MFD Networked with Sensors and GMS10 Port ExpanderSerial cableEthernet cableTransducer cablexxxxxxxxx
