Raymarine RayNet & SeatalkHS

High Speed Ethernet based networking systems for Raymarine equipment. Both systems carry the graphical and video based data between devices. Data such as cartography, radar, echosounder, video and internet access when connected via a YachtSense Link Router. 

The difference being the cabling systems. Adaptor cables are available to add new equipment to older cabling, but data speed may become an issue on larger systems.
