Description
The Raymarine YachtSense Master Module is the brains of the YachtSense Digital Control System and the starting point for every installation. It is the central processor that maps your vessel's wiring to the digital switching pages shown on a connected Raymarine chartplotter, giving complete command of lighting, pumps, motors and other electrical loads from one screen.
The Master Module is the main connection point to the Raymarine Axiom chartplotter network, linking the system over both RayNet Ethernet and a SeaTalkng / NMEA 2000 backbone. Two J1939 and two RS-485 connections allow integration of OEM smart devices such as air-conditioning units and chillers. A 1.8 inch colour LCD with button controls provides manual override, channel status and on-module diagnostics. Remote modules are added over SeaTalkng to expand the system to as many as 400 channels, and the Master Module ships complete with a YachtSense Power supply module.
