- The NMEA 0183 Interface Standard defines electrical signal requirements, data transmission protocol and time, and specific sentence formats for a 4800-baud serial data bus. This standard is intended to support one-way serial data transmission from a single talker to one or a few listeners. This data is in printable ASCII form and may include information such as position, speed, depth, frequency allocation, etc.
- This standard operates at a 38.4K-baud rate. Specific sentence formats are same as NMEA 0183.
- This standard contains the requirements of a serial data communications network to inter-connect marine electronic equipment on vessels. The standard describes a low-cost moderate capacity bi-directional, multi-transmitter/multi-receiver instrument network to interconnect marine electronic devices.
It is based on CAN (Controller Area Network). Although this standard is 50 times faster than NMEA 0183, it is not intended to support high-bandwidth applications such as video.
