Maritime navigation and radiocommunication equipment and systems - Digital interfaces - Part 1: Single talker and multiple listeners

Scope

Contains the requirements for data communication between maritime electronic instruments, navigation and radiocommunication equipment when interconnected via an appropriate system. Is intended to support one-way serial data transmission from a single talker to one or more listeners. This data is in printable ASCII form and may include information such as position, speed, depth, frequency allocation, etc. For applications where a faster transmission rate is necessary, reference should be made to IEC 61162-2. Is closely aligned with NMEA 0183 version 3.01. The main changes with respect to the previous edition include among others: - Clause 7 (Clause 5 in the previous edition) has been expanded to include two types of start of sentence delimiters. The conventional delimiter '$' is used with the conventional sentences which are now called parametric sentences. A new delimiter '!' identifies sentences that conform to special purpose encapsulation.
