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.

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.
Figure 6 – Mounting
Panel Cutout Dimension
Connecting the VMM6 consists of plugging the unit into the
vessel’s NMEA 2000® network. The unit can be connected to the NMEA 2000 network
directly with the 6 position Deutsch DT Series receptacle molded into the unit
or via use of the A3702 VMM to NMEA 2000® Adapter
Cable.

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).
Figure
7 - NMEA 2000 Connectors
Please refer to the Maretron website (www.maretron.com/products/cabling.php
) for relevant products.
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.
Figure 8 – General
Tab Dialog Box
When connected to a NMEA 2000® network this read-only
field will indicate the indicator bank instance value that will be transmitted
with the switch status in the 127501 Binary Status Report status message. To
change the value of this field, change the value of the VMM6 device instance,
as shown in Advanced Tab.
The VMM6 has six switches. The top and bottom of each
switch has a separate indicator output number. Reference the indicator number
needed from

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.
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.)
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.
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.
Regular maintenance is important
to ensure continued proper operation of the Maretron VMM6. Perform the
following tasks periodically:
• Clean the unit with a soft cloth. Do not use chemical
cleaners as they may remove paint and markings or may corrode the CLMD16
enclosure or seals. Do not use any astringent cleaners such as acetone, MEK,
Alcohol, Etc. These cleaners will deteriorate the VMM6 unit’s casing and
actuators.
• Ensure that the unit is mounted securely and cannot be
moved relative to the mounting surface.
• Check the security of the cable connected to the NMEA
2000® connector and tighten if necessary.
If you notice
unexpected operation of the Maretron VMM6, follow the troubleshooting
procedures in this section to remedy simple problems. If these
steps do not solve your problem,
please contact Maretron Technical Support. Refer to page 16 for contact information.
