VMM6 User’s Manual Rev.1.1 2
Theory of Operation
The mechanical throw type for each switch must be programmed into the module via CAN
message(s). Switch position will be reported via the NMEA2000® Standard 127501 “Binary
Status Report” message. To allow each switch to report up to three discrete positions, the top and
bottom switch positions will be considered separate binary (on or off) switches and will be
numbered as follows:
There is a total of twelve blue LEDs, each configurable via CAN message to act as a backlight or
a function indicator. The LEDs are located under the top and bottom of each actuator. All LEDs
set as backlights will share the same brightness and on/off values. LEDs set as status indicators
can be tied to a channel of any device on the CAN network that reports the NMEA2000®
standard “Binary Status Report” message. When the associated channel reports it is in the “on”
state, the LED will be turned on. When the associated channel reports it is in the “off” state, the
LED state will turn off.

Choosing Installation Location
Please consider the following when choosing a mounting location.
•The VMM6 is waterproof, so it can be installed in a damp or dry location.
•Consider mounting depth. (6” recommended clearance needed for proper cable bend radius)
•The VMM6 is temperature-rated to 85°C (185°F). Mount VMM6 away from engines or engine rooms
where the operating temperature exceeds the specified limit.
•After mounting, ensure cable strain relief.
Mounting the VMM6
Locate the panel mounting template supplied with the VMM6. After cutting the panel mounting hole,
simply press the VMM6 into panel cutout. The VMM6 mounting tabs will securely hold the unit into
place provided the minimum panel thickness of 0.06” (1.5 mm) is present. The use of silicone
sealant is acceptable to prevent water intrusion behind the unit and in some cases to secure the
unit. Do not use permanent adhesive to secure unit. Certain adhesives such as methacrylate will
cause cracking of the plastic enclosure. Adhesive use for installation will void warranty of VMM6
unit. For reference to the needed panel cutout dimensions see Figure 6.

NMEA 2000® Connection
The NMEA 2000® connector is the round five-pin male connector found on the VMM to NMEA
2000® Adapter Cable.This connector is known as a DeviceNet micro connector. You connect the
VMM6 to a NMEA 2000® network using a Maretron NMEA 2000® cable (or compatible cable) by
connecting the female end of the cable to the male NMEA 2000 connector on the VMM to NMEA
2000® Adapter Cable (note the key on the male connector and keyway on the female connector).
Be sure the cable is connected securely and that the collar on the cable connector is tightened
firmly. Connect the other end of the cable by plugging into the 6 position connector on the rear of
the VMM6, applying pressure until the connector latch clicks. The VMM6 is designed so that you
can plug or unplug it from an NMEA 2000® network while the power to the network is connected or
disconnected. Please follow recommended practices for installing NMEA 2000® network products.
NMEA 2000 connections can be made using pre-assembled leads or may be made using field
attachable connectors and cables (See: Figure 7).

Configuring the VMM6
The VMM6 transmits data over an NMEA 2000® network as it is shipped from the factory. The
default device instance is “Instance 51”. The default data instance whose state is reflected by the
LED’s on the VMM6 is “Instance 32”. The unit will pair with Maretron CLMD12 and CLMD16 to
toggle each unit’s first 6 ECB’s ON and OFF. If more than one CLMD12, CLMD16 or one of each
unit is on the same NMEA 2000® network the VMM6 unit will have to be configured. Depending
on desired switch control, default configuration may not work for your application and custom
configuration will be needed. The VMM6 is configured using Maretron N2KAnalyzer®. The
following sections describe the configurable parameters of the VMM6.

Positions
Each switch has a “Positions” setting which controls its behavior, and settings which control the
lighting of the LED’s behind the top and the bottom of each switch.
There are two possible settings for this parameter that control the behavior of the switch:
2 Position: The rocker switch acts as a two-position toggle switch. When powered on, the indicator
for the top of the switch will transmit the state OFF, and the indicator for the bottom of the switch will
transmit the state ON, and these two values will remain the same until the top of the switch is
pressed. When the top of the switch is pressed, the indicator for the top of the switch will transmit
the state ON, and the indicator for the bottom of the switch will transmit the state OFF, and these
two values will remain the same until the bottom of the switch is pressed. When the bottom of the
switch is pressed, the indicator for the top of the switch will transmit the state OFF, and the indicator
for the bottom of the switch will transmit the state ON, and these two values will remain the same
until the top of the switch is pressed.
3 Positions: The rocker switch acts as two momentary switches. When powered on, the indicator for
the top of the switch will transmit the state OFF, and the indicator for the bottom of the switch will
also transmit the state OFF. When the top of the switch is pressed, the indicator for the top of the
switch will transmit the state ON as long as the top of the switch is pressed. When the top of the
switch is released, the indicator for the top of the switch will again transmit the state OFF. When the
bottom of the switch is pressed, the indicator for the bottom of the switch will transmit the state ON
as long as the bottom of the switch is pressed. When the bottom of the switch is released, the
indicator for the bottom of the switch will again transmit the state OFF.
Top and Bottom Data Instance and Indicator
If the Use As Backlight option is deselected, this Data Instance and Indicator will be the instance
information in which the VMM6 will be tethered to via PGN.
The LED behind the corresponding switch will be lit or flashing whenever the Indicator that
corresponds to the selected Data Instance is transmitting an On or fault state on the network. The
LED on the switch will be dark otherwise.
(If the “Use As Backlight” option is selected the value of these fields will be ignored.)

VMM6 User’s Manual_________________________________________
11 VMM6 User’s Manual Rev.1.1
Top and Bottom Use As Backlight
If this option is selected, then the LED behind the top (or bottom, as appropriate) of the switch will
be lit at all times, and the “Data Instance” and “Indicator” fields will be ignored.
Advanced Tab
Figure 9 –Advanced Tab Dialog Box
This tab contains the Device Instance setting; If there are multiple instances of this device on a
network, each would be set to a separate instance.
