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

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication should be clearly indicated
in the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability should attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC should not be held responsible for identifying any or all such patent rights.
International Standard IEC 61162-1 has been prepared by IEC technical committee 80:
Maritime navigation and radiocommunication equipment and systems.
This third edition cancels and replaces the second edition published in 2000, and constitutes a
technical revision. This part of IEC 61162 is closely aligned with NMEA 0183 version 3.01.
It also replaces PAS 61162-100 (2002), PAS 61162-101 (2003) and PAS 61162-102 (2003).
The main changes with respect to the previous edition are listed below:
• Normative references have been renumbered from 1.2 to 2, Terms and definitions from 1.3
to 3 and Manufacturers documentation from 2 to 4. Thereafter all clauses are numbered
two ahead of those in the previous edition.
• 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
61162-1 © IEC:2007(E) – 5 –
sentences that conform to special purpose encapsulation. The example applications in
Clause 9 (Clause 7 in the previous edition) have been expanded to describe both types.
• The tables in Clause 8 (Clause 6 in the previous edition) have been updated. The previous
Table 5 (Approved sentence formatters) and the associated Annex A (Minimum required
sentences) have been deleted.
• Clause 8 has been expanded to include new and revised sentences.
• Four new annexes have been added to support the text.
The text of this standard is based upon the following documents:
