Overview
EN 61162-401:2002 (IEC 61162-401:2001) is a European adoption of an international standard that defines the application profile for digital communications between shipboard navigation and radiocommunication equipment. Focused on a multiple talkers / multiple listeners architecture for ship systems interconnection, the standard describes the communication protocol at the application layer and how it relies on the underlying transport layers (layers 1–4, the “T‑profile”) as specified in Part 410.
Key facts:
- Title: Maritime navigation and radiocommunication equipment and systems - Digital interfaces - Part 401: Multiple talkers and multiple listeners - Ship systems interconnection - Application profile
- Adopted as EN in 2002; national adoptions (e.g., Slovenia) followed
- Annexes A, B, C and ZA are normative; Annex D is informative
Key Topics and Requirements
- Application profile definition: Specifies the intended behavior, roles and services at the application layer for interoperable ship systems interconnection.
- Multiple talker/multiple listener model: Describes architecture assumptions where many devices can transmit and many can receive on the ship network.
- Dependence on T‑profile: Requires realization of physical/transport/profile layers (layers 1–4) as defined in IEC/EN 61162-410 (transport profile).
- Normative references and character sets: Uses and references international standards such as IEC 61162-400/410/420, IEEE 754, ISO/IEC 8859-1 and ISO/IEC 10646-1; also cites RFC 2500 for related internet protocol guidance.
- Conformance structure: Includes normative annexes and informative guidance to support consistent implementation and compliance testing.
Practical Applications
- Integration of shipboard navigation and radiocommunication systems where interoperability and reliable data sharing are required across multiple devices.
- Enables consistent application layer behavior for equipment such as radar interfaces, electronic chart systems, communication systems, autopilots and other bridge systems (generalized to navigation/radiocomms equipment).
- Useful in system design for newbuilds, retrofits and for vendors developing compliant marine equipment and software.
Who Would Use This Standard
- Marine equipment manufacturers and firmware/software developers
- System integrators and shipboard network designers
- Shipbuilders and naval architects specifying onboard interfaces
- Classification societies and maritime authorities evaluating compliance
