Product Description

The NMEA 2000 simulator uses the Teensy 4.0 module (included in the scope of delivery). It is useful for testing NMEA 2000 devices on the bench. Six PGNs are adjustable via potentiometers and two per onboard switches. We also provide open-source firmware, which allows adding and modifying NMEA 2000 PGNs.

NMEA 2000 is a marine networking standard designed and managed by the National Marine Electronics Association (NMEA). The NMEA is an association of marine electronics manufacturers, dealers, and technicians.

The NMEA 2000 standard defines a low-cost, modest capacity, bi-directional, multi-transmitter, multi-receiver instrument network. The hardware layer is based on CAN (Controller Area Network). Typical data on an NMEA 2000 network 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.

Advanced Marine Electrics and Electronics Troubleshooting: A Manual for Boatowners and Marine TechniciansAdvanced Marine Electrics and Electronics Troubleshooting

Whether you are a marine electronics professional or a boat owner, Advanced Marine Electrics and Electronics Troubleshooting helps you understand the new, more powerful methods of troubleshooting marine electrical and electronic systems.

A modern boat’s sophisticated installations and networked electronics can stretch the traditional diagnostic methods based on trouble lights and multimeters past their useful limits. 

This book will show you how to:

  • Use microprocessor-based diagnostic tools and techniques from the automotive and communications sectors, adapted for boats for the first time
  • Diagnose the most difficult AC and DC problems
  • Protect communications and navigation electronics from interference and lightning
  • Seek out and eliminate stray-current sources and galvanic corrosion
