Full-function, NMEA 2000® network wired remote controller with full color LCD display

The MMR-40 is a NMEA 2000® Network Controller engineered to add full-function, auxiliary control to MediaMaster® source units.

Outfitted with a NMEA 2000® Micro-C connector, the MMR-40 connects to a host MediaMaster® source unit in two ways:

Once connected, the MMR-40 automatically recognizes the host MediaMaster® source unit and will then mirror all host source unit controls and screen info onto the MMR-40's full-color, 2.8-inch LCD display, resulting in a complete MediaMaster® user experience.

The MMR-40 is equipped with independent display theme and lighting controls for maximum mounting location flexibility, regardless of the settings on the host source unit. Engineered for real-world marine (and many outdoor) applications, its weatherproof (IP66 rated) chassis is built to withstand the harshest environments.

Note: The MMR-40 is not a stand-alone receiver and does not function without a connected MediaMaster® source unit. All remote control functionality of the MMR-40 is solely derived from the host source unit. Functionality of the MMR-40 requires connection to a NMEA 2000® network or use of MMC-PN2K powered network cables (sold separately).
