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 shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall 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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 61162-450 has been prepared by IEC technical committee 80: Maritime navigation and
radiocommunication equipment and systems. It is an International Standard.
This third edition cancels and replaces the second edition published in 2018. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) clarification of serial to network gateway function (SNGF) in 4.5 with the addition of two new
figures;
– 8 – IEC 61162-450:2024 © IEC 2024
b) addition of further destination multicast addresses and port numbers in 6.2;
c) clarification of TAG block parameters in 7.2 together with Annex B, a new Annex H and
associated tests in 8.9.4;
d) clarification of the sender process for binary files in 7.3.6 and the receiver process for binary
files in 7.3.7 with updated Figure 6 and Figure 7;
e) clarifications of SFI collision detection and use of SRP sentence in 7.5 together with a new
Annex G;
f) revision of tests for handling malformed data received on the serial line in 8.5.5.
The text of this International Standard is based on the following documents:

radio-communication equipment. This document is based on the application of an appropriate
suite of existing international standards to provide a framework for implementing data transfer
between devices on a shipboard Ethernet network.
This document specifies an Ethernet based bus type network where any listener can receive
messages from any sender with the following properties.
• This document includes provisions for multicast distribution of information formatted
according to IEC 61162-1, for example position fixes and other measurements, as well as
provisions for transmission of general data blocks (binary file), for example between radar
and VDR, and also includes provisions for multicast distribution of information formatted
according to IEC 61162-3, for example position fixes and other measurements.
• This document is limited to protocols for equipment (network nodes) connected to a single
Ethernet network consisting only of OSI level one or two devices and cables (network
infrastructure).
• This document provides requirements only for equipment interfaces. By specifying protocols
for transmission of IEC 61162-1 sentences, IEC 61162-3 PGN messages and general binary
file data, these requirements will guarantee interoperability between equipment
implementing this document as well as a certain level of safe behaviour of the equipment
itself.
• This document permits equipment using other protocols than those specified in this
document to share a network infrastructure, provided that it is supplied with interfaces which
satisfy the requirements described for ONF.
• This document includes provisions for filtering of the network traffic in order to limit the
amount of traffic to manageable level for each individual equipment.
This document does not contain any system requirements other than the ones that can be
inferred from the sum of individual equipment requirements. An associated standard,
IEC 61162-460, further addresses system requirements.
