The Shadow-Caster® SCM-LC-N2K-PLUS is an RGB LED light controller for boats with an NMEA 2000 network. The SCM-LC-N2K-PLUS connects to the network through your NMEA 2000 backbone cable. Doing so allows it to operate your RGB lights through your multi-function display. An ethernet cable may also be needed for older model MFDs.  Switches can even be added to turn individual lights on and off.
