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:

 

A picture containing text, electronics

Description automatically generated

 

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.

Installation

 

Installing the Maretron VMM6 involves the following steps.

 

Unpacking the Box

 

When unpacking the box containing the Maretron VMM6, you should find the following items:

 

1 – VMM6 Digital Switch Module

1 – VMM6 User’s Manual on USB flash drive

1 – VMM6 Panel Installation Template

1 – Warranty Registration Card

1 – A3702 VMM to NMEA 2000® Adapter Cable - .2m

 

If any of these items are missing or damaged, please contact Maretron Technical Support

(please refer to page 16 for contact information).

 

Choosing Installation Location

 

Please consider the following when choosing a mounting location.

 

 

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.

Figure 6 – Mounting Panel Cutout Dimension

Connecting the VMM6

 

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.

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).

 

 

Figure 7 - NMEA 2000 Connectors

 

Please refer to the Maretron website (www.maretron.com/products/cabling.php ) for relevant products.

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.)

 

 

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.

Maintenance

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.
