1      Introduction

Congratulations on your purchase of the Maretron Network Bus Extender. Maretron has designed and built your NBE100 to the highest standards for years of dependable and accurate service.

 

Maretron's NBE100 (Network Bus Extender) allows you to extend the maximum node count, network trunk length and cumulative drop length of any NMEA 2000® network. The NBE100 solves bus errors and other electrical issues caused by exceeding any of these limitations and makes design of large networks easier. NMEA 2000® networks have a maximum of 50 nodes allowed on a single network, a maximum network trunk length of 200m and a maximum cumulative drop length of 78m. If you have a network that exceeds any of these specifications, you can simply disconnect the network trunk in the middle and connect the ends to the NBE100, along with additional termination resistors. This will split the network into two electrical segments, each of which can have up to 50 nodes, for a total of 100 nodes on the logical network. The NBE100 will transparently route NMEA 2000® messages between the two network segments, making them work as a single logical NMEA 2000® network. Advanced priority-based message routing ensures that higher-priority messages are always prioritized over lower-priority messages, enabling predictable and reliable network operation.

 

For exceptionally large networks, multiple NBE100’s may be used.

 

1.1      Firmware Revision

This manual corresponds to NBE100 firmware revision 1.0.0.

 

1.2      NBE100 Features

The Maretron NBE100 has the following features.

 

 

1.3      NBE100 Accessories

Maretron offers the following accessories for the NBE100:

 

 

1.4      Quick Install

Installing the Maretron NBE100 involves the following five steps. Please refer to the individual sections for additional details.

 

1.    Unpack the box (Section 2.1)

2.    Choose a mounting location (Section 2.2)

3.    Mount the NBE100 (Section 2.3)

4.    Connect the NBE100 (Section 2.4)

 

2      Installation

2.1      Unpacking the Box

When unpacking the box containing the Maretron NBE100, you should find the following items:

 

1 – NBE100 – Network Bus Extender

1 – Parts Bag containing 4 Stainless Steel Mounting Screws

1 – NBE100 User’s Manual

1 – Warranty Registration Card

 

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 NBE100 is waterproof, so it can be mounted in a damp or dry location.
  2. The orientation is not important, so the NBE100 can be mounted on a horizontal deck, vertical bulkhead, or upside down if desired.
  3.  The NBE100 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 NBE100

Attach the NBE100 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 NBE100

 

2.4      Connecting the NBE100

The NBE100 requires one type of electrical connection: the NMEA 2000® connections (refer to Section 2.4.1).

 

2.4.1     NMEA 2000® Connection

The NBE100 has two NMEA 2000® connectors. The NMEA 2000® connectors can be found on either end of the enclosure.

 

The NMEA 2000® connectors are round five pin male connector (see Figure 2). You connect the NBE100 to an NMEA 2000® network using a Maretron NMEA 2000® cable (or compatible cable) by connecting the female end of the cable to the NBE100 (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 NBE100 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

The NBE100 is installed on an NMEA 2000® network between the two sections that you wish to physically isolate. There is no electrical connection through the NBE100, so you must ensure that each of the two NMEA 2000® networks connected to the NBE100 must have separate power sources and two termination resistors. This means that if you use an NBE100 to split an existing network into two separate networks, you must provide one additional power connection and two additional termination resistors (one for each side of the NBE100).

 

The two NMEA 2000® connectors are labeled “N2K PORT A(PWR)” and “N2K PORT B”. Logically, these connectors are identical; that is, you can connect the NBE100 between two networks in either way and it will function identically. However, the NBE100 sources power only from the connector marked “N2K PORT A(PWR)”. It uses no power from the connector labeled “N2K PORT B”.

 

Figure 3 below shows the installation of an NBE100 into a simple NMEA 2000® network.

 

For exceptionally large networks, multiple NBE100’s may be used to segment the network into more than two segments. Each segment must have its power connection and two termination resistors.

2.4.2     Checking Connections

Once the NMEA 2000® connections to the NBE100 have been completed, check to see that information is being properly transmitted by using an appropriate NMEA 2000® display to observe a sensor on the opposite side of the NBE100. If you don’t see data from that sensor, refer to Section 4, “Troubleshooting”.

 

2.5      Configuring the NBE100

The NBE100 will function on the NMEA 2000 network as it is shipped from the factory; no user configuration is required. However, it may be desirable to perform optional configuration. There are several configurable items within the NBE100, which are detailed in the remainder of this section.

 

You configure the NBE100 using a Maretron DSM250 display or other NMEA 2000® display unit that is capable of configuring the NBE100. Please refer to the Maretron DSM250 User’s Manual for details.

 

2.5.1     Device Instance

NMEA 2000® provides a unique device instance for each device on a vessel. This value should be programmed in each NBE100 so that each NBE100 is associated with a unique device instance number. The default instance number is 0, which is used to indicate the first NBE100 that is hooked to the network. Subsequent NBE100’s connected to the network would be numbered 1, 2, and so on.

 

2.5.2     Device Label

Program this parameter with a text string which identifies this particular NBE100, to allow you to easily distinguish it from other NBE100’s on the network.

 

2.5.3     Advanced Configuration…

Certain parameters do not normally need to be set in order for normal operation, but are included in an advanced configuration section for use in special situations.

 

2.5.3.1    Restore Factory Defaults

Selecting this configuration option causes all stored parameters in the NBE100 to be reset to the values they contained when the unit was manufactured.

 

3      Maintenance

Regular maintenance is important to ensure continued proper operation of the Maretron NBE100.  Perform the following tasks periodically:

 

 

4      Troubleshooting

If you notice unexpected operation of the Maretron NBE100, 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 Section 6 for contact information).

 

Symptom

Troubleshooting Procedure

No devices on one side of the NBE100 are visible from a display connected to the other side.

  • Ensure that the NBE100 is properly connected to the NMEA 2000® network segments.
  • Ensure that both NMEA 2000 network segments have power.
  • Ensure that both NMEA 2000 network segments have two termination resistors fitted.

 

 

5      Technical Specifications

As Maretron is constantly improving its products, all specifications are subject to change without notice. Maretron products are designed to be accurate and reliable; however, they should be used only as aids to navigation and not as a replacement for traditional navigation aids and techniques.
