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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62386-101 has been prepared by subcommittee 34C: Auxiliaries
for lamps, of IEC technical committee 34: Lamps and related equipment.
This second edition cancels and replaces the first edition published in 2009. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) collection of all bus timing requirements defined in IEC 62386-101:2009 and
IEC 62386-102:2009 and rework of the timing requirements to facilitate the preparation of
a future control devices standard, taking particular account of the requirements for multi-
master systems. The 10 % tolerances have been replaced by minimum and maximum
timing values;
b) integration of multi-master timing requirements;

– 8 – IEC 62386-101:2014 © IEC 2014

c) extension of the defined forward frames;
d) addition of wiring requirements;
e) improvement of the bus power supply requirements;
f) improvement of test sequences and description of the test sequences in the form of
pseudo code instead of flow charts.
The text of this standard is based on the following documents:
FDIS Report on voting
34C/1098/FDIS 34C/1111/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This Part 101 is intended to be used in conjunction with:
• Part 102, which contains general requirements for the relevant product type (control gear),
and with the appropriate Part 2xx (particular requirements for control gear);
• Part 103, which contains general requirements for the relevant product type (control
devices), and the appropriate Part 3xx (particular requirements for control devices).
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of the IEC 62386 series, under the general title: Digital addressable lighting
interface, can be found on the IEC website
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct

INTRODUCTION
IEC 62386 contains several parts, referred to as series. The 1xx series includes the basic
specifications. Part 101 contains general requirements for system components, Part 102
extends this information with general requirements for control gear and Part 103 extends it
further with general requirements for control devices.
The 2xx parts extend the general requirements for control gear with lamp specific extensions
(mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific
features.
The 3xx parts extend the general requirements for control devices with input device specific
extensions describing the instance types as well as some common features that can be
combined with multiple instance types.
This second edition of IEC 62386-101 is published in conjunction with IEC 62386-102:2014
and with the various parts that make up the IEC 62386-2xx series for control gear, together
with IEC 62386-103:2014 and the various parts that make up the IEC 62386-3xx series of
particular requirements for control devices. The division into separately published parts
provides for ease of future amendments and revisions. Additional requirements will be added
as and when a need for them is recognised.
The setup of the standard is graphically represented in Figure 1 below.
