IEC 61162-1 Ed. 4.0 en:2010

IEC 61162-1:2010(E) 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. Typical messages may be from about 11 to a maximum of 79 characters in length and generally require transmission no more rapidly than one message per second. For applications where a faster transmission rate is necessary, reference should be made to IEC 61162-2. The main changes with respect to the previous edition are listed below:
- certain sentences have been removed as they are not used by other standards prepared by technical committee 80;
- new sentences have been added; corrections have been made to certain sentences (ABK, BBM, DOR, FIR, SSD, TUT, and VTG);
- new fields have been added to certain sentences;
- three additional tests have been added to Annex B.
