1      General

1.1   Introduction

Congratulations on your purchase of the Maretron Vessel Data Recorder (VDR100). Maretron has designed and built your vessel data recorder to the highest standards for years of reliable, dependable, and accurate service.


The Vessel Data Recorder (VDR100) records all NMEA 2000® network activity onto a user-supplied USB flash drive. The VDR100 can be accessed over a Ethernet LAN using Maretron’s N2KExtractor® program, which lets you view graphs of the collected data, maps of the course traveled during data collection, and lets you export selected parameters into comma delimited (.CSV) files for detailed statistical analysis with Microsoft Excel or other programs which accept the comma-delimited format. Alternatively, the USB flash drive can be removed and inserted into a Windows PC running Maretron’s N2KExtractor® program, where the same analysis can be performed.


The VDR100 has an NMEA 2000® port for recording information from the attached NMEA 2000® network, a USB port for connecting the USB flash drive, and an Ethernet LAN (Local Area Network) port for accessing data remotely.


The Maretron VDR100 is designed to operate within the harsh demands of the marine environment.  However, no piece of marine electronic equipment can function properly unless installed, calibrated, and maintained in the correct manner.  Please read carefully and follow these instructions for installation, calibration, and usage of the Maretron VDR100 in order to ensure optimal performance.

1.5   Quick Install

Installing the Maretron VDR100 involves the following steps. Please refer to the individual sections for additional details.


1.    Unpacking the Box (Section 2.1)

2.    Choosing a Mounting Location (Section 2.2)

3.    Mounting the VDR100 (Section 2.3)

4.    Connecting the VDR100 (Section 2.4)

5.    Configuring the VDR100 (Section 3)


1.6   Theory of Operation

The VDR100 records every frame of NMEA 2000® network activity onto the attached USB flash drive.


1.6.1  General Concepts    Data Recording

The VDR100 records every single frame of data on the NMEA 2000® network.


In order to perform performance analysis, the time at which each event occurs must be accurately recorded. To this end, there must be a source of time information on the NMEA 2000® network, for example, a Maretron GPS or equivalent.






At least one device transmitting valid data in the NMEA 2000® System Time (126992) message, for example, a GPS receiver, must be operating on the network in order for the VDR100 and the N2KExtractor® program to be able to correlate the data with the time when it was present on the network.


The VDR100 records data to a circular buffer on the USB flash drive. When the USB flash drive becomes near full, the oldest data on the device is deleted in order to make room for newer data.


You may monitor the available space on a USB flash drive using N2KView® software or a Maretron DSM150/DSM250 display. If you wish to keep all recorded data on the USB flash drive, simply remove the USB flash drive from the VDR100 and replace it with an empty USB flash drive before the first USB flash drive becomes full.    Flash File System

The USB flash drive will be re-formatted the first time it is used in the VDR100. This is done i[H2] n order to ensure filesystem integrity of the USB flash drive in the cases of removal of the device from the VDR100 and also in cases of power removal from the VDR100,






When you plug a new USB flash drive (one which has never been used before in a VDR100) into the VDR100, ALL DATA ON THE MEMORY DRIVE WILL BE DESTROYED. If your USB flash drive has data you wish to save, please archive it before plugging the USB flash drive into the VDR100.



The filesystem that is created on the USB flash drive is not compatible with Microsoft Windows. Drivers for the filesystem used by the VDR100 are included with the Maretron N2KExtractor® software.


1.6.2  Operating States

The VDR100 has several different operating states, which can be monitored by observing the USB LED on the unit, or by monitoring the VDR Status message transmitted by the VDR100 using a DSM150, DSM250, or N2KView® software.

·         Recording – the VDR100 is recording data

·         Formatting – the VDR100 is formatting the USB flash drive for use, and will begin recording when complete

·         Erasing – the VDR100 is erasing old files from the USB flash drive, and will begin recording when complete

·         No Flash Drive – no USB flash drive is present; insert a USB flash drive into the VDR100

·         Error – the VDR100 has detected an error on USB flash drive; check the USB flash drive

·         Initializing – the VDR100 is initializing the USB flash drive, and will begin recording when complete

·         Incompatible – the VDR100 has detected an incompatible USB flash drive which contains VDR100 upgrade software; either remove and erase the USB flash drive or replace it with a different USB flash drive for recording data


1.6.3  TCP/IP Networks

The networking protocol that is used for the communication between the PC running N2KExtractor® software and the VDR100 is the TCP/IP protocol.  This protocol is used by the World Wide Web, FTP (File Transfer Protocol), and many others of the most popular applications on the Internet.  The TCP/IP connection can be made over an Ethernet connection, a Wi-Fi connection, cellular phone data connection, and many other types of media.  In fact, a single packet of TCP/IP data may traverse multiple types of media on its journey. The TCP/IP protocol is supported by most operating systems, as well as Internet-connected cellular phones.


Each computer on a TCP/IP network is identified by an IP address unique to that network. An IP address consists of four numbers, each ranging between 0 and 255, separated by periods.  This is referred to a dotted decimal notation.  Examples of IP addresses in this format are, and


The IP address may either be hard coded into the computer (this means that the address is static which makes the computer easier to find) or assigned at each startup by a DHCP (Dynamic Host Control Protocol) server, typically found as part of a router. The router can be configured to reserve a specific address for the computer and then assign that same address each time at startup. If the router chooses a different address each time, then the computer may be difficult to find on the network. This is not a problem for a client such as N2KExtractor®, but servers such as the VDR100 should be at a known address.    NAT (Network Address Translation)

If you wish to use N2KExtractor® to view data from a VDR100 on a WAN through an Internet connection, please read this section.  If your N2KExtractor® computer and the VDR100 are on the same LAN, you may skip this section.


In the early days of the Internet, each computer connected to the Internet had its own IP address. With the explosive growth of the Internet, the number of distinct IP addresses is starting to run out.  It is no longer practical for an Internet Service Provider (ISP) to provide its customers with individual IP addresses for each component the customer wishes to connect to the Internet.  Rather, the ISP normally assigns each customer a single IP address, and a router implementing Network Address Translation (NAT) is connected to the Internet connection (sometimes referred to as the Wide Area Network, or WAN, connection) on one side, and to the Local Area Network, or LAN, on the other side.  Each computer on the LAN side of the connection will be assigned its own IP address, typically in the ranges 192.168.x.x, 10.x.x.x, and 172.16.x.x through 172.31.x.x, where x can be any number in the range 0-255.  The WAN connection will be assigned a single IP address by the ISP.


Generally, network address translation is performed by a router that is connected to the Internet via a Cable or DSL connection on the WAN side, and to the local area network (LAN) via Ethernet or Wi-Fi connections.  In order to access a VDR100 on the local area network from an N2KExtractor® outside of the LAN, you must configure the router to allow incoming connections on port 6544 and to forward these connections to the IP address of the VDR100.  Consult the documentation that came with your router for details.    PAT (Port Address Translation)

If you wish to use N2KExtractor® to view data from a VDR100 on a WAN through an Internet connection and your Internet Service Provider does not allow communication on port 6544, please read this section.  If your N2KExtractor® computer and VDR100 are on the same LAN, or your ISP allows communication over port 6544, you may skip this section.


The VDR100 requires a connection to be made on port 6544. Routers that support Port Address Translation can be set up to accept incoming connections on a different port and to forward these connections to port 6544 on the IP address of the VDR100. This change in the port address is known as the ability to do Port Address Translation as well as Network Address Translation. Not all routers have this ability; please consult the documentation that came with your router for details.


N2KExtractor® must then be set up to request a connection to the WAN IP Address of the router and the new port number.    Static and Dynamic IP Addressing

If you wish to use N2KExtractor® to view data from a VDR100 on a WAN through an Internet connection, please read this section.  If your VDR100 and your N2KExtractor® computer are on the same LAN, you may skip this section.


If you request a Static IP Address from your ISP when you set up your Internet connection, the WAN IP address will always be the same.  If you didn’t make this request, your ISP will assign you a Dynamic IP Address, which may actually change from time to time.  In this way, the ISP only needs to have enough addresses to cover its customers who are connected to the Internet at any given time.  If you stop or lose your Internet connection, your Dynamic IP address will be released and may be reassigned to someone else.


If you wish to connect to a VDR100 from outside your vessel’s LAN via an Internet connection, you have two choices. First, you can request a static IP address from the ISP for your vessel; secondly, you may register your VDR100’s IP address with a “dynamic DNS service”, such as the ones offered freely by www.dyndns.org, among others. Please visit their websites for more information on how dynamic DNS services operate.    Data Security and Encryption

Making your vessel’s data available over a LAN or WAN presents multiple security concerns.  First, it is desirable to keep anyone from viewing your vessel’s data without authorization.  Second, and more important, it is imperative that no unauthorized persons be able to place data onto your vessel’s NMEA 2000® network.


The VDR100 protects your vessel’s data with multiple levels of protection. 


First, any data that passes between the VDR100 and any N2KExtractor® station components is protected using industry-standard SSL encryption. This encryption standard is widely used to protect financial information on the internet.  Each communication session negotiates a random encryption key every time a connection is established.  This makes the data secure over public and private Wi-Fi networks, as well as the internet. 


Second, each N2KExtractor® station that wishes to connect to a VDR100 must authenticate itself by means of a password.  The password is transmitted by the N2KExtractor® station to the VDR100 over the encrypted communication link.  The VDR100 compares the password to the one it was programmed with.  Only if the password received from the station matches the VDR100’s stored password is the station granted access to the NMEA 2000® network data.


1.7      Data Analysis

In order to retrieve data from the VDR100, either

1)    access the VDR100 over a LAN from a Windows PC on which N2KExtractor® software has been installed, or

2)    remove the USB flash drive from the VDR100 and plug into a Windows PC on which N2KExtractor® software has been installed.


Please refer to the N2KExtractor® User’s Manual for details.






Do not plug a USB flash drive that has been used in a VDR100 into a Windows PC without first installing the Maretron N2KExtractor® software. Failure to install the N2KExtractor® software before plugging in the USB flash drive may result in the data on the flash memory device being destroyed.







If a USB flash drive that has been used in the VDR100 is plugged into a Windows PC that has not had the N2KExtractor® software installed, then Windows will not recognize the format of the USB flash drive and will ask you to format it. DO NOT FORMAT THE USB FLASH drive, as this WILL result in all of the data on the USB flash memory drive being destroyed.


2      Installation

2.1   Unpacking the Box

When unpacking the box containing the Maretron VDR100, you should find the following items:


·         1 – VDR100 Vessel Data Recorder

·         1 – Parts Bag containing 4 Stainless Steel Mounting Screws

·         1 – VDR100 User’s Manual

·         1 – Warranty Registration Card

·         1 – USB Flash Drive (preformatted for the VDR100)


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


2.2   Choosing a Mounting Location

Please consider the following when choosing a mounting location.


  1. The VDR100 is waterproof, so it can be mounted in a damp or dry location. Note that the USB Waterproof Cover accessory must be installed to waterproof all of the connections to the VDR100. If the Ethernet LAN Interface is used, the Waterproof Ethernet Cable must be installed to waterproof the Ethernet LAN connection. The NMEA 2000® network interface is already waterproof.
  2. The orientation is not important, so the VDR100 can be mounted on a horizontal deck, vertical bulkhead, or upside down if desired.
  3.  The VDR100 is temperature-rated to 55°C (130°F), so it should be mounted away from engines or engine rooms where the operating temperature exceeds the specified limit. 


2.3   Mounting the VDR100

Attach the VDR100 securely to the vessel using the included stainless steel mounting screws or other fasteners as shown in Figure 1 below. Do not use threadlocking compounds containing methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of the plastic enclosure.




Figure 1 – Mounting the VDR100


2.4      Connecting the VDR100

2.4.1  NMEA 2000® Connection

The NMEA 2000® connector can be found on the side of the enclosure. The NMEA 2000® connector is a round five pin male connector (see Figure 2). You connect the VDR100 to an NMEA 2000® network using a Maretron NMEA 2000® cable (or an NMEA 2000® compatible cable) by connecting the female end of the cable to the VDR100 (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 (male) to the NMEA 2000® network in the same manner. The VDR100 is designed such 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.

Figure 2 – NMEA 2000® Connector Face Views


2.4.2  LAN Connection

The VDR100 has one external RJ-45 LAN connector. The RJ-45 connector enables connection to an external network, which is necessary for N2KExtractor® to be able to connect to the VDR100. The LAN connector can be made waterproof with the purchase of the optional PX837/5M00 Waterproof Ethernet Cable, which has a waterproof cover which engages the threads on the RJ-45 LAN connector, creating a waterproof seal.


3      Configuring the VDR100

The VDR100 has several configurable parameters, which are shown below including the default values. If you are not using the default values, then you will need to refer to the corresponding section for configuring the VDR100 appropriately. You may configure the VDR100 using a Maretron DSM150 or DSM250 display or Maretron N2KAnalyzer® software.


3.1      Advanced Configuration

3.1.1  Device Instance

Program this parameter to the desired instance number for this device. You can program this parameter to any value between 0 and 252. The default device instance is 0


3.1.2  Installation Description

This entry allows you to modify the NMEA 2000® installation description text strings.  You can enter any information you like here, such as the date the unit was installed, or the location in which it was installed, for later reference.  Tools such as Maretron N2KAnalyzer® allow you to view these values later. The default installation description is blank text.


3.1.3  Restore Factory Defaults

This option restores all settings on the VDR100 device to their factory default states.


3.2      Label

Program this parameter with a text string which identifies this device.  Maretron display products will display this label text when you are selecting data to display. The default device label is blank.


3.3      Password

Program this parameter with a text password. Any connecting N2KExtractor® clients must be programmed with the same password in the “Connections Settings->Password” field in the N2KExtractor® software. The default password is blank.


3.4      Configuring DHCP

This parameter determines whether or not the VDR100 obtains its LAN connection settings from a DHCP server on the local area network. When set to “Yes” (the default value), the VDR100 will obtain all necessary connection settings (IP Address, Subnet Mask, Default Gateway, and Default DNS)  from a DHCP server on the local area network. Most routers have the capability to act as a DHCP server. Consult the user documentation for your network’s router for details.


If there is no DHCP server on the local area network (or if the VDR100 is connected directly to a PC running N2KExtractor®), set the “DHCP” parameter to “No” and manually configure the IP Address (section 3.5), Subnet Mask (section 3.6), Default Gateway (section 3.7), Default DNS (section 3.8).


3.5      Configuring IP Address

This parameter is the IP (Internet Protocol) address used by the VDR100. You will need to specify this address to N2KExtractor® clients in order to allow them to connect to the VDR100. If the “DHCP” parameter is set to “Yes”, you do not need to configure this parameter. If the “DHCP” parameter is set to “No”, you will need to configure this parameter.


3.6      Configuring Subnet Mask

This is a mask used to divide an IP Address into subnets. Basically, it tells the computer how much of the IP Address defines the network, and how much may be used by computers on the network. For most networks, the first three parts of the IP address define the network (i.e., every computer on the network must have the same values), and the last part defines the computer (i.e., every computer on the network must have a different value). Where the value 255 appears in the subnet mask, the values define the network and must be the same.


The most common value is


If the “DHCP” parameter is set to “Yes”, you do not need to configure this parameter. If the “DHCP” parameter is set to “No”, you will need to configure this parameter.


3.7      Configuring Default Gateway

This is the IP address of the router. If the “DHCP” parameter is set to “Yes”, you do not need to configure this parameter. If the “DHCP” parameter is set to “No”, you will need to configure this parameter.


3.8      Configuring Default DNS

This is the IP address of a computer on the Internet that can identify and locate computer systems and resources on the internet. In most cases, this should not be required by the VDR100 and may be left blank. If the “DHCP” parameter is set to “No”, you will need to configure this parameter.


4      Usage

4.1      Recording Data

To record data, plug a USB flash drive into the Type A USB connector on the VDR100.

A waterproof cover accessory is available that will allow the USB port to be made waterproof with a USB flash drive installed, although this cover will not fit all USB flash drives, so please check the dimensions of the USB flash drive to be sure that the waterproof cover accessory will fit over the drive.


4.2      USB Flash Drive Selection

4.2.1  USB[FE3]  Flash Drives






Because of the methods that the VDR100 records every frame of network data for quick retrieval and analysis, the VDR100 must only be used with a high performance USB flash drive from the list of supported USB flash drives.


The VDR100 is supported ONLY with the following list of USB flash drives (more will be added in the future):

4.3      Monitoring the VDR100

4.3.1  Indicators

The VDR100 has three green LED indicators on its top surface:


NMEA 2000:             This light will be red for several seconds after powerup while the VDR100 is initializing itself. Once this process is complete, this light will be lit a steady green to indicate that the main processor is active. The light will blink on and off to indicate data being transferred over the NMEA 2000® connection. If this light is lit red after the initialization has completed, it indicates that a problem has been detected.


LAN:   This light will be on steadily to indicate that there is an active link connection between the VDR100 and the attached device. The light will blink on and off to indicate data being transferred over the LAN connection. If the light is off, then there is no active link connection.


USB: This light will indicate the operating state of the VDR100. Please refer to Section 1.6.2, “Operating States”, for details of the different states.

If within the applicable period any such products shall be proved to Maretron’s satisfaction to fail to meet the above limited warranty, such products shall be repaired or replaced at Maretron’s option. Purchaser's exclusive remedy and Maretron’s sole obligation hereunder, provided product is returned pursuant to the return requirements below, shall be limited to the repair or replacement, at Maretron’s option, of any product not meeting the above limited warranty and which is returned to Maretron; or if Maretron is unable to deliver a replacement that is free from defects in materials or workmanship, Purchaser’s payment for such product will be refunded. Maretron assumes no liability whatsoever for expenses of removing any defective product or part or for installing the repaired product or part or a replacement therefore or for any loss or damage to equipment in connection with which Maretron’s products or parts shall be used.  With respect to products not manufactured by Maretron, Maretron’s warranty obligation shall in all respects conform to and be limited to the warranty actually extended to Maretron by its supplier. The foregoing warranties shall not apply with respect to products subjected to negligence, misuse, misapplication, accident, damages by circumstances beyond Maretron’s control, to improper installation, operation, maintenance, or storage, or to other than normal use or service.




Statements made by any person, including representatives of Maretron, which are inconsistent or in conflict with the terms of this Limited Warranty, shall not be binding upon Maretron unless reduced to writing and approved by an officer of Maretron.




Maretron does not warrant that the functions contained in any software programs or products will meet purchaser’s requirements or that the operation of the software programs or products will be uninterrupted or error free. Purchaser assumes responsibility for the selection of the software programs or products to achieve the intended results, and for the installation, use and results obtained from said programs or products. No specifications, samples, descriptions, or illustrations provided Maretron to Purchaser, whether directly, in trade literature, brochures or other documentation shall be construed as warranties of any kind, and any failure to conform with such specifications, samples, descriptions, or illustrations shall not constitute any breach of Maretron’s limited warranty.
