Overview

The JL Audio 010-03135-00 is an NMEA 2000 network MFD data interface that brings JL Audio MediaMaster controls onto a compatible multifunction display at the helm. It runs on 10 to 15.9 VDC and joins the NMEA 2000 backbone through a Micro-C port (LEN 1), while using its Ethernet port to communicate with the MediaMaster source unit.

Mounted behind the helm or inside a dry electronics space, the module measures 6.77 in wide x 3.98 in deep x 1.73 in high and supports an operating temperature range of -20 C to +65 C (-4 F to +149 F). Once it is on the network, the interface can mirror the familiar MediaMaster screens on the MFD so volume, source, and zone changes stay within reach while you are running the boat.

Key features

• NMEA 2000 Micro-C connection with LEN 1 (50 mA network load) for integration on NMEA 2000 backbones
• 12V system power input range of 10 to 15.9 VDC, with a wiring harness that includes a 1A fuse
• Ethernet connection to the MediaMaster source unit for on-screen control from the helm display
• Works with supported JL Audio MediaMaster source units: MM105, MM105-HR, MM55, and MM55-HR
• Compatible with supported MFD platforms including Garmin, Simrad, B&G, and Lowrance displays
• Maximum current draw of 150 mA
• USB 2.0 port for software updates
• Operating temperature range of -20 C to +65 C (-4 F to +149 F)

What's included

• NMEA 2000 network MFD data interface module
• Wiring harness with 1A fuse
• Four stainless steel mounting screws

Installation and setup

The module installs as a network device rather than a replacement stereo. It needs a powered NMEA 2000 network connection via the Micro-C port, and it also needs its power harness connected to a 12V DC supply within the 10 to 15.9 VDC input range.

Plan for the usual NMEA 2000 hardware at the helm or behind it: a tee to add a drop, plus the right backbone and drop cables for your run. The USB port is used for software updates only.

Compatibility and fit

This interface is for boats running a compatible JL Audio MediaMaster source unit and a compatible MFD that supports the on-screen control pages. The NMEA 2000 network carries the data between the helm and the module, while Ethernet links the module to the MediaMaster source unit.

Before ordering, confirm your MediaMaster model is one of the supported units and that your NMEA 2000 backbone has an open tee location and enough network power budget for a LEN 1 device.

Use on board

It is a good match for boats where the stereo is mounted away from the helm, such as in a cabin, console, or equipment locker, and you still want quick access to zones and sources while docking or running offshore.

The low current draw and wide operating temperature range make it a sensible fit for typical helm electronics spaces when the mounting area is kept dry and the wiring is strain-relieved for vibration.
