HS5 SeaTalkhs Network Switch The HS5 SeaTalkhs Network Switch works with Raymarine\'s latest c-Series and e-Series Multifunction Displays and accessories and serves as the central connection point for the SeaTalk High Speed Network. The HS5 uses the new Raynet waterproof connection system found on c-Series and e-Series displays, and provides a secure, reliable weather tight connection. Up to 5 displays or other peripherals can be connected directly to the HS5 network switch. The 5 ports all support 10 or 100 Megabit speeds when connected to peripherals like displays, scanners, sounder modules or thermal cameras. The 5th port also supports Gigabit speed for interconnecting multiple HS5 switches together on very large networks. The compact HS5 works on both 12V and 24V dc power systems, and is simple to install with large keyhole mounting slots and front-facing status indicators. HS5 - What\'s in the box? The HS5 is available with the features, options, and accessories described below. Refer to the packing list enclosed with your HS5 shipment to determine the actual contents of your package. Information shared using the SeaTalk hs network includes shared cartography (between compatible displays), digital radar data and sonar data. Key Features 12V or 24V DC 5 port - Watertight RayNet connection 10Mbit/sec, 100Mbit/sec and 1000 Mbit/sec (5th port only) supported network speeds. Gigabit 5th port allows higher speed across switches should a 2nd switch be necessary Multiple Switches Systems with more than 5 SeaTalk hs devices require more than one network switch. Network switches can be connected together (\"daisy-chaining\") for this purpose. The network switch provides a dedicated high-speed (1000 Mbit/S) port for connecting switches together while still retaining full data bandwidth throughout the system. Each switch only has one high-speed port (port 5), so you can only connect up to 2 switches using the high-speed (1000 Mbit/S) connection. Any additional network switches must be connected together using a standard speed (100 Mbit/S) port. Note: The maximum number of SeaTalk hs devices that can be connected in any single system is 25. « less
