This part of IEC 61162 contains the requirements for data communication between maritime
electronic instruments, navigation and radiocommunication equipment when interconnected
via an appropriate system.
This part of IEC 61162 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.
The electrical definitions in this standard are not intended to accommodate high-bandwidth
applications such as radar or video imagery, or intensive database or file transfer
applications. Since there is no provision for guaranteed delivery of messages and only
limited error checking capability, this standard should be used with caution in all safety
applications.
For applications where a faster transmission rate is necessary, reference should be made to
IEC 61162-2.
