Overview
EN IEC 61162-450:2024 - "Maritime navigation and radiocommunication equipment and systems - Digital interfaces - Part 450: Multiple talkers and multiple listeners - Ethernet interconnection" defines interface requirements and test methods for high‑speed communication over a shipboard Ethernet network. The standard provides a framework, based on existing international standards, for data transfer between shipboard navigation and radiocommunication equipment and other ship systems that need to exchange that data. It supersedes the 2018 edition and was endorsed by CENELEC in 2024.
Key topics and technical requirements
The standard covers both high‑level application behavior and low‑level network constraints. Major technical topics include:
- Network architecture and topology: requirements for connecting equipment and network infrastructure on shipboard Ethernet.
- Multiple talkers / multiple listeners model: rules for devices acting as concurrent transmitters and receivers on the same Ethernet segment.
- Transport layer and protocols: use of IP, UDP multicast, TCP point‑to‑point, IP addressing, multicast address ranges and port assignments.
- Application layer formats: datagram header structure, TAG block parameters, message and binary‑file transfer formats (UDP multicast and TCP file transfer).
- Gateway functions: Serial‑to‑Network Gateway (SNGF) and PGN‑to‑Network Gateway (PNGF) behavioral and buffer management requirements.
- Network control and optimization: IGMP filtering for multicast, differentiated services (DS Field), maximum data‑rate limits and traffic filtering.
- Reliability and diagnostics: error logging, handling malformed data, address conflict detection and system function ID resolution.
- Low‑level requirements: electrical/mechanical interfaces and conformance to Ethernet (IEEE Std 802.3) and optical fibre safety where applicable.
- Methods of test: test setups and required results for verifying equipment and infrastructure compliance.
Practical applications and users
EN IEC 61162-450:2024 is used to design, integrate and verify shipboard Ethernet systems that exchange navigation and radiocommunication data. Typical users and beneficiaries include:
- Marine equipment manufacturers implementing compliant Ethernet interfaces.
- System integrators and shipbuilders designing ship networks that carry navigation/radio data.
- Network engineers and onboard IT teams responsible for configuration and testing of shipboard Ethernet.
- Test laboratories and certification bodies conducting compliance and interoperability testing.
- Regulatory and procurement teams specifying networked navigation/radiocommunication solutions.
Adopting this standard ensures robust multicast communication, predictable data rates, and consistent gateway behavior for mixed device environments on ships.

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

1 Scope
This part of IEC 61162 specifies interface requirements and methods of test for high speed
communication between shipboard navigation and radiocommunication equipment as well as
between such systems and other ship systems that need to communicate with navigation and
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.
