4.1 General
According to IMO Resolution MSC.333 (90):2012, Clause 8 and IEC 61996-1:2013, 4.3.5, interfacing
between the various sensors and VDR shall be in accordance with the relevant international interface
standard (IEC 61162 series), where possible. As a minimum, the sentences that VDR is to support are
given in IEC 61996-1:2013, Annex A.
In case there is no free interface port available for the connection to the VDR, a “data splitter”-interface
should be added for providing the additionally required output port of a sensor. A “data splitter”-
interface shall comply with IEC 60945.
It is also specified that any connection to any item of the ship’s equipment shall be such that operation
of that equipment suffers no deterioration, even if the VDR system develops faults. [IMO Resolution
MSC.333 (90):2012, Clause 8].
It may be noted that the use of signals defined under common standards results in fewer problems
for the installation of any VDR, even if the interfaces of several mandatory shipborne equipment are
(still) not internationally standardized, such as VHF communication signals, radar image, watertight
door/fire door/hull opening (door) status signals and alert signals. It is therefore desired on the
installation planning phase that equipment output signals should at least be in accordance with the
alternative signals that are specified in Clause 5.
4.2 Input signals required for VDR interfaces
To promote common understanding among equipment manufacturers, ship builders and operators,
the signals used for the interfaces between sensors and the VDR are described in 4.2.1 to 4.2.6, 4.3 and
4.4. Forms for filling in and checking the details for each individual input to the VDR are provided in
5.2 to 5.21.
4.2.1 Signals defined in applicable parts of IEC 61162 series
The characteristics of “talkers” and “listeners” referred to IEC 61162-1. With regard to VDR interfacing,
the VDR is considered the “listener” and the sensors are considered the “talkers”. Thus, when planning
VDR installation, care shall be taken to ensure that sensors and VDR are compatible in terms of interface
signal types.
a) IEC 61162-1 and IEC 61162-2
IEC 61162-1 and IEC 61162-2 are of the single-talker and multi-listener type communication. The
difference between types is the communication speed, i.e. 4 800 bps by IEC 61162-1 and 38,4 kbps
4 © ISO 2016 – All rights reserved
---------------------- Page: 9 ----------------------
ISO 22472:2016(E)
by IEC 61162-2. At present, IEC 61162-1 is normally used for communications between marine
equipment, except that IEC 61162-2 is used for AIS interfaces and sometimes gyro compass.

NOTE No. 15 is a “talker” and not recording data for VDR.
b) IEC 61162-450
IEC 61162-450 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. IEC 61162-450 provides a higher speed and higher capacity alternative to the IEC 61162-1
and IEC 61162-2 standards while retaining these standards’ basic data format.
Sentences available for use for VDRs are listed in Table 1.
NOTE 1 Appropriate methods to ensure network safety and security may be applied.
NOTE 2 IEC 61162-460 is published.
4.2.2 Signals other than IEC 61162 format
Any interface units which may be required to convert non-IEC 61162 signals, shall conform to the
requirements of IEC 60945 (IEC 61996-1:2013, 4.3.5).
According to the requirement that any connection to any item of the ship’s equipment shall be such that
operation of that equipment suffers no deterioration, even if the VDR system develops faults [IMO Resolution
MSC.333 (90):2012, Clause 8], interface signals shall be provided by the sensors in such a way, that
failures of the VDR or of cables connecting the VDR cannot hamper the functionality of the source
equipment, i.e. contacts or signals of equipment for primary ship manoeuvring functions shall be
provided as “dry contacts” or through isolation amplifiers.
Signal formats not specified in IEC 61996-1 such as “contact” signal and analogue signals (e.g. voltage,
current, synchro and pulse, etc.) except Bridge and Communications audio signals, have to be converted
to a “serial signal” before they can be interfaced to VDR.
© ISO 2016 – All rights reserved 5
---------------------- Page: 10 ----------------------
ISO 22472:2016(E)
In some VDR units, a signal converter will be included. In other instances, it will be possible to insert a
converter between the sensor and the VDR. Thus in most instances of non-standard signals, it should
still be possible to achieve an interface. However, there are still many sensors which output analogue
signals and it is recommended that operators, shipbuilders and owners ensure that interface between
specific equipment is possible.
4.2.3 Bridge audible sound captured by microphones
In accordance with IEC 61996-1:2013, 4.6.5 [IMO Resolution MSC.333 (90):2012, 5.5.5], requirement
of microphone is as follows. Microphones shall be positioned on the bridge covering all work stations as
described in MSC/Circ.982 so that conversation is recorded. The recording shall be such that, on playback,
a normal speaking voice shall provide adequate intelligibility while the ship is performing its normal
operations. This performance shall be maintained at all work stations while there is a single audio alarm
anywhere on the bridge or any noise, including noise from faulty equipment or mounting, or wind. This shall
be achieved through the use of at least two channels of audio recording. Microphones positioned outside on
bridge wings, shall be recorded on at least one additional separate channel.
In addition, it is stated in IEC 61996-1:2013, 5.6.1 that the microphones forming the bridge audio data
source are to be c

ISO/DIS 22472
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22472 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee
SC 6, Navigation and ship operations.
This second edition cancels and replaces the first edition (ISO 22472:2006) of which has been technically
revised.

DRAFT INTERNATIONAL STANDARD ISO/DIS 22472
Ships and marine technology — Guidelines for the operation
and installation of voyage data recorder (VDR)
1 Scope
The purpose of this document provides guidance for the planning, installation and operational testing of VDR
installations according to specifications of IMO Resolution MSC.333 (90) and associated IEC 61996-1:2013.
These standards mainly deal with interfaces between VDR and external sensors, which are the main subject
for technical agreements amongst user, shipyard, VDR supplier and/or sensor manufacturers when
installations are planned. In addition, matters of performance test and playback are described as well.
Furthermore, details for checking of items related to the interfaces and the installation are introduced. This
standard is not intended for the standardization of performance factors and functional requirements related to
VDR.
When whole or partial replacement of an existing simplified VDR (S-VDR) is required, this document provides guidance
according to the requirements of IMO Resolution MSC.163(78) and IEC 61996-2 for installation of the items concerned.
NOTE All text of this International Standards which is identical to that of IMO Resolution MSC.333(90) and/or IEC
61996-1:2013 are formatted in italics, and the Regulation and associated performance standard clause numbers are
indicated in brackets, where necessary.

4 VDR interface
According to IMO Resolution MSC.333 (90)/8 and IEC 61996-1:2013/4.3.5, interfacing between the various
sensors and VDR shall be in accordance with the relevant international interface standard IEC 61162 series,
where possible. As a minimum, the sentences that VDR is to support are given in Annex A of IEC 61996-
1:2013.
In case there is no free interface port available for the connection to the VDR, a "data splitter"-interface should
be added for providing the additionally required output port of a sensor. A ‘data splitter-interface’ shall comply
with IEC 60945.
It is also specified that any connection to any item of the ship’s equipment shall be such that operation of that
equipment suffers no deterioration, even if the VDR system develops faults. (MSC.333 (90)/8).
It may be noted that the use of signals defined under common standards results in fewer problems for the
installation of any VDR, even if the interfaces of several mandatory shipborne equipment are (still) not
internationally standardised, such as VHF communication signals, radar image, watertight door / fire door /
hull opening (door) status signals and alert signals. It is therefore desired on the installation planning phase
that equipment output signals should at least be in accordance with the alternative signals that specified on
paragraph 5 of this guideline.
4.1 Input signals required for VDR interfaces
To promote common understanding amongst equipment manufacturers, ship builders and operators, the
signals used for the interfaces between sensors and the VDR are described in clauses 4.1.1 to 4.1.6, 4.2 and
4.3. clauses 5.1 to 5.20 then provide forms for filling in and checking the details for each individual input to
the VDR.
4.1.1 Signals defined in applicable parts of IEC 61162 series
IEC 61162
The characteristics of ‘talkers’ and ‘listeners’ referred to IEC 61162-1. With regard to VDR interfacing the
VDR is considered the ‘listener’ and the sensors are considered the ‘talkers’. Thus, when planning VDR
installation, care shall be taken to ensure that sensors and VDR are compatible in terms of interface signal
types.
a) IEC 61162-1 and IEC 61162-2

---------------------- Page: 9 ----------------------
ISO/DIS 22472
IEC 61162-1 and IEC 61162-2 are of the single talker and multi-listener type communication. The difference
between types is the communication speed, i.e. 4 800 bps by IEC 61162-1 and 38,4 kbps by IEC 61162-2. At
present, IEC 61162-1 is normally used for communications between marine equipment, except that IEC
61162-2 is typically used for Gyro compass and AIS interfaces.

b) IEC 61162-450
IEC 61162-450 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. IEC
61162-450 provides a higher speed and higher capacity alternative to the IEC 61162-1 and IEC 61162-2
standards while retaining these standards’ basic data format.
Sentences available for being used for VDR are listed in table 1.
4.1.2 Signals in other than IEC 61162 format
Any interface units which may be required to convert non-IEC 61162 signals, shall conform to the
requirements of IEC 60945 (IEC 61996-1 / 4.3.5).
According to the requirement that any connection to any item of the ship’s equipment shall be such that
operation of that equipment suffers no deterioration, even if the VDR system develops faults (MSC. 333(90)
/8), interface signals shall be provided by the sensors in such a way, that failures of the VDR or of cables

ISO/DIS 22472
connecting the VDR cannot hamper the functionality of the source equipment: i.e. contacts or signals of
equipment for primary ship manoeuvring functions shall be provided as “dry contacts” or via isolation
amplifiers.
Signal formats not specified in IEC 61996-1 such as ‘contact’ signal and analogue signals (e.g. voltage,
current, synchro and pulse, etc.) except Bridge and Communications audio signals, have to be converted to a
‘serial signal’ before they can be interfaced to VDR.
In some VDR units a signal converter will be included. In other instances it will be possible to insert a
converter between the sensor and the VDR. Thus in most instances of non-standard signals it should still be
possible to achieve an interface. However, there are still many sensors which output analogue signals and it
is recommended that operators, shipbuilders and owners ensure that interface between specific equipments is
possible.
4.1.3 Bridge audible sound captured by microphones
In accordance with IEC 61996-1:2013/4.6.5 Bridge audio (MSC. 333(90) /5.5.5), requirement of microphone is
as follows. Microphones shall be positioned on the bridge covering all work stations as described in
