NMEA 2000 is a marine networking standard created and administered by the National Marine Electronics Association (NMEA). The NMEA is an association of marine electronics manufacturers, dealers, and technicians.
The NMEA 2000 standard describes a low-cost, moderate capacity, bi-directional, multi-transmitter, multi-receiver instrument network. Typical data on a network using this standard include position latitude and longitude, GPS status, steering commands to autopilots, waypoint lists, wind sensor data, engine sensor data, depth sounder sensor data, and battery status data.
NMEA 2000 is the most consequent and straightforward adaptation of SAE J1939. NMEA 2000 is a modernized version and replacement of an older standard, NMEA 0183. It has a significantly higher data rate (250k bits/second vs. 4.8k bits/second for NMEA 0183). It also uses a binary message format as opposed to the ASCII serial communications protocol used by NMEA 0183. Another distinction between the two protocols is that NMEA 2000 is a multiple-talker, multiple-listener data network, whereas NMEA 0183 is a single-talker, multiple-listener serial communications protocol.

SAE J1939 Starter Kit And Network Simulator
Our JCOM.J1939 Starter Kit And Network Simulator is designed to allow the experienced engineer as well as the beginner to experiment with SAE J1939 data communication without the need of connecting to a real-world J1939 network, i.e. a diesel engine. It may sound obvious, but in order to establish a network, you need at least two nodes, and that fact applies especially to CAN/J1939 where the CAN controller will basically shut down after transmitting data without receiving a response. For that reason, our jCOM.J1939 Starter Kit And Network Simulator consists of two J1939 nodes, namely our jCOM.J1939.USB, an SAE J1939 ECU Simulator Board With USB Port.
Warwick Control Technologies (UK) announced the release of their SAE-J1939-based protocol stack kits that also support an NMEA 2000 protocol stack according to IEC 61162-3.The company's development kit provides the protocol stack in C source-code, an STM32 prototyping board, a reference design CAN Bus driver for STM32 microcontrollers, the X-Analyser tool, and the Leaf Light USB dongle by Kvaser, [...]
As part of our business strategy of providing prototyping solutions for the CAN Bus (including SAE J1939, ISOBUS, NMEA 2000) we have decided to focus more on the Arduino platform, specifically the Arduino Due. The Due, while providing the power of an ARM Cortex M3 processor, comes with two CAN Bus ports per default, however, lacking [...]
Maretron introduced their J2K100 gateway, which can be attached to a J1939-based network of marine engines, while the other CAN Bus port supports NMEA 2000 (IEC 1162-3). The gateway collects SAE J1939 engine data and forwards it to the NMEA 2000 connected display. It listens to the J1939 network and draws no power from it (power is derived from [...]

Worth over $100 Billion dollars globally each year, the heavy equipment market is constantly working to remain competitive in harsher environments while becoming more efficient. There are always areas of the vehicles that require the high performance of traditional metal connectors. In other areas of the vehicle, however, high quality thermoplastic connectors with superior terminal [...]
