CONTROL OPTIONS ^1

To operate, the MM55-HR must be connected with a compatible NMEA 2000 ^® device (not included) using applicable NMEA 2000 ^® cables and connectors (sold separately).

MediaMaster® MMR-40 Network Controller

Full-function, water-resistant (IP66 rated) controller with full-color LCD display

Connection for NMEA 2000 ^® Networks

Micro-C plug permits direct connection to a vessel network using accessory cables and connectors (sold separately). Note: Functionality requires compatible entertainment protocols (PGN) for NMEA 2000 ^4 networks and may require a software upgrade of your multifunction display (MFD). Refer to your MFD manufacturer for device compatibility info.

1. Control functionality will vary depending on the connected controller option. Full functionality requires connection to a MMR-40 Network Controller (sold separately) or your compatible MFD with a MMA-1-HTML MFD Data Interface (sold separately).
