JL Audio MMR-40 User manual

MediaMaster® NMEA 2000®

Network Controller

Product Description

The MMR-40 is a NMEA 2000® network

controller designed to add full-function

auxiliary control to MediaMaster® source units.

Featuring a color LCD display and water-

resistant (IP66 rated) design, the MMR-40

connects directly to vessel networks using

applicable NMEA 2000® cables and connectors

(sold separately).

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).

Safety Considerations

• While this product is designed to be water-

resistant, it should never be submerged

under water or subjected to high-pressure

water spray.

• Do not mount in areas of extreme heat.

• Ensure this product is securely installed so

that it does not come loose in the event

of a collision/sudden jolt or as a result or

repeated vibrations during normal operation.

• Check before drilling to make sure that you

will not be drilling into a fuel tank, gas/brake

line, wiring harness, or other vital system.

• Secure all wiring as needed, using cable

ties or wire clamps to protect them from

moving parts and sharp edges.

• Always follow proper safety procedures and

wear eye-protection at all times with a dust

mask and gloves when cutting.

General Command Functions

Below is a list of general source unit functions

that are controlled by the MMR-40.

Note: The functionality of some commands will

vary depending on the specific MediaMaster®

source unit connected to the network.

Mounting & Installation

The diagram below shows a typical

mounting procedure into a fiberglass panel.

A mounting template is included to aid

in measuring and marking the mounting

surface before cutting or drilling.

Make sure to carefully plan the routing of

the remote’s connection cables prior to

cutting or drilling any panels.

1. Press along the perforation to remove the

center section of the mounting template.

(Discard the center section.) The template

can be used to verify there is sufficient flat

surface area for mounting and as a guide

for cutting the opening. Tape the template

to the mounting location and mark the

surface for cutting the opening and drilling

pilot holes.

2. Use a jigsaw or rotary tool to cut an

opening in the mounting surface. If

necessary, use a file or sandpaper to

adjust the opening for proper fitment and

smooth the edges.

3. Place the MMR-40 into the opening and

check that the mounting holes remain

aligned with the pilot hole marks taken

from the template. If not, adjust and mark

new holes as necessary.

Connections

The MMR-40 is equipped with a NMEA 2000®

Micro-C connector and can connect to a

host MediaMaster® source unit in the two

methods shown below. The USB connector is

used for future software updates.

• Direct interface with a vessel’s NMEA 2000®

network using applicable NMEA 2000®

cables and connectors (not included).

• Direct connection of one MMR-40 with

one host MediaMaster® source unit using

JL AUDIO® MMC-PN2K powered network

cables (sold separately) to simulate an

isolated, stand-alone NMEA 2000® network.

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.

4. Remove the MMR-40 and drill four (4) pilot

holes in the mounting surface at the pilot

hole marks.

5. Peel the adhesive backing from the

mounting gasket and affix to the rear of

the bezel. Connect all wiring and place the

MMR-40 into the opening.

6. Secure the MMR-40 using the four (4)

mounting screws. Press the trim ring onto

the front of the MMR-40.
