Overview

The JL Audio Powered Network Cable for MediaMaster Source Units is a powered NMEA 2000 cable used to link a compatible MediaMaster source unit with one MediaMaster MMR-40 NMEA 2000 Network Controller or a compatible MFD on a small, stand-alone NMEA 2000 segment.

It is offered in 6 ft (1.83 m) and 25 ft (7.62 m) lengths for clean routing from the helm area to an audio source location, while keeping the network simple and contained.

This cable setup supports a maximum of two NMEA 2000 devices. If your boat has additional NMEA 2000 devices on the same network, plan on a full NMEA 2000 backbone instead, since this powered cable is not used in that type of network build.

Key features

• Creates an isolated, stand-alone NMEA 2000 segment to connect a compatible MediaMaster source unit with one MMR-40 controller or a compatible MFD.
• Supports a maximum of two NMEA 2000 devices on the segment.
• Length options: 6 ft (1.83 m) or 25 ft (7.62 m) for short runs or longer routing through consoles and rigging paths.
• For MM100s (not MM100s-BE), an adapter is required: MMC-DN2K-1 or MMC-DN2K-6 to adapt the Deutsch connector to an NMEA 2000 5-pin Micro-C connector.
• Not used with a full NMEA 2000 backbone when the network includes additional NMEA 2000 devices beyond this two-device limit.

Variants

This product is available in multiple lengths to match different helm-to-source routing distances on board.

The only difference between the options is cable length.

• 010-13858-00: Length 6 ft (1.83 m). A shorter run that keeps routing tidy when the source unit and control point are close together.
• 010-13859-00: Length 25 ft (7.62 m). Extra reach for boats where the source unit is mounted farther from the helm or where the cable needs to follow longer rigging routes.

What’s included

• Powered network cable (selected length)

Installation and setup

Route the cable like other network wiring on a boat: support it along the run, avoid tight bends, keep it away from chafe points, and leave a small service loop at each end for future access. If the run passes through a console or bulkhead, use proper grommets or conduit to protect the jacket.

Because this cable is intended for a small, stand-alone NMEA 2000 segment, confirm your system plan before pulling wire. It fits setups where a single compatible MediaMaster source unit needs NMEA 2000 integration with one MMR-40 controller or a compatible MFD, without building out a larger NMEA 2000 backbone.

Compatibility and system planning

This cable is a good match for boaters who want MediaMaster control and integration on NMEA 2000 with a simple two-device segment, such as a helm display paired with an audio source unit. If your vessel already runs multiple NMEA 2000 instruments or you need to add more devices later, a standard NMEA 2000 backbone is the better network foundation.
