Powered Network Cable for connection of compatible NMEA 2000® MediaMaster® source units - 6 ft (1.83 m) This powered network cable is designed to simulate an isolated, stand-alone NMEA 2000® network for the connection of a compatible MediaMaster® source unit (sold separately) with one MediaMaster® MMR-40 NMEA 2000® Network Controller (sold separately) or compatible MFD (Multi-Function Display). Note: JL Audio® Powered Network Cables support a maximum of two NMEA 2000® devices. For systems with additional NMEA 2000® devices, a genuine NMEA 2000® network must be assembled, which does not support JL Audio® Powered Network Cables. Connection of MM100s (not MM100s-BE) requires MMC-DN2K-1 or MMC-DN2K-6 to adapt the Deutsch connector on the MM100s to a NMEA 2000® 5-pin Micro-C connector.
