5. Engineers SAE has developed an electronic communication networking standard for the automotive industry called J1939 which is used on many larger diesels and some gasoline engines Likewise the National Marine Electronics Association NMEA has developed an electronic communication networking standard for the marine industry called NMEA 2000 which is used for navigation information as well as other vessel data such as engine information These two networks are now beginning to coincide more and more on vessels and Maretron has developed a gateway for bridging the two networks together via its J1939 NMEA 2000 gateway J2K100 This application note provides a basic overview of the two networks and how the J2K100 is used to bridge engine and genset information from the J1939 network to an NMEA 2000 network 2 NMEA 2000 Network Basics An NMEA 2000 network consists of two or more nodes electronic boxes interconnected together using NMEA 2000 approved cable and connectors A typical NMEA 2000 network is shown in Figure 1 Maretron Micro Maretron Micro Maretron Micro Male Terminator Powertap Tee Male Terminator TR CM CF SPWRO5 CF TR CM Maretron I M EO Maretron Micro Double p Ended Cordsets Connection 4 CM CG1 CF XX 0 Maretron Tank Maretron Level Adapter Display TLA100 DSM200 DSM250 Figure 1 Typical NMEA 2000 Network The trunk or backbone horizontal cable and connectors shown in Figure 1 usually runs

7. In this scheme each engine usually uses a source address of zero 0 3 1 SAE J1939 Recommended Cabling and Connectors Maretron highly recommends that you purchase and understand two documents published by SAE which describe the recommended cables and connectors used for J1939 networks approximately 100 These documents J1939 11 and J1939 15 provide important information for cabling and connectors used to interconnect the J2K100 with the J1939 network You can find these documents at the following web page http www sae org standardsdev groundvehicle 1939a htm Deutsch Industrial Products Division is a supplier of J1939 connectors their catalog can be found at the following link http Awww deutschipd com cans pdf 4 Determining J1939 Network Type Before installing Maretron s J2K100 it is imperative to understand the type of J1939 network you are dealing with which may be one of the following Single Engine Genset No Existing J1939 Network Single Engine Genset Single J1939 Network Figure 2 Two Engines Gensets No Existing J1939 Network Two Engines Gensets Single J1939 Network Figure 3 Two Engines Gensets Dual J1939 Networks Figure 4 aRWND 4 1 Single Engine Genset No Existing J1939 Network Installation Although an engine or genset may have a J1939 interface a particular installation may not have an existing J1939 network because no other device is connected In this case it will be necessary to

Registration Card If any of these items are missing or damaged please contact Maretron 2 2 Choosing a Mounting Location The J2K100 is mounted between the J1939 network and the NMEA 2000 network Please consider the following when choosing a mounting location 1 The J2K100 is waterproof so it can be mounted in a damp or dry location 2 The orientation is not important so the J2K100 can be mounted on a horizontal deck vertical bulkhead or even upside down if desired 3 The J2K100 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 J2K100 Attach the J2K100 securely to the vessel using the included brass mounting screws or other fasteners as shown in Figure 1 below Figure 1 Mounting the J2K100 Page 2 Hevision 1 2 www busse yachtshop de info busse yachtshop de Maretron 2 4 Connecting the J2K100 The J2K100 requires two electrical connections as shown in Figure 2 Refer to Section 2 4 1 for making the NMEA 2000 connection and Section 2 4 2 for making the J1939 connection Additional information can be found in Appendix B Interfacing J1939 Engines and or Gensets to an NMEA 2000 Network Using Maretron s J1939 to NMEA 2000 Gateway J2K100 NMEA 2000 connector NMEA 2000 port J1939 Port J1939 Field Attachable Connector Female Figure 2 J2K100 Electrical Connections
