NMEA 2000 / SeaTalkng
The current marine industry standard. All current Raymarine MFDs are NMEA2000 certified. The standard utilizes the CAN (Control Area Network) design developed by Bosch for the automotive market but with messages/sentence appropriate for the marine industry.
A multi-talker, multi-listener approach using serial data at moderate date rates (250kbs).
Under the NMEA standard, manufacturers can use the cable/connector design of their choice so long as it conforms to certain requirements. The topology is a robust terminated backbone/spur design.
Raymarine’s proprietary cable system for use in NMEA 2000 networks. The design provides two advantages. First, the connector collars are retained on the product which allows for a smaller cable diameter making installations easier. More importantly, the cable can include a sixth wire which allows for backward compatibility with SeaTalk1 equipment. Products with SeaTalkng connectors can be used on NMEA 2000 networks that use Devicenet cabling through simple connector adaptors and conversely equipment with Devicenet connectors can be used on NMEA 2000 networks that use SeaTalkng cabling through simple connector adaptors.
