FOREWORD

1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.

3) The documents produced have the form of recommendations for international use and are published in the form

of standards, technical specifications, technical reports or guides and they are accepted by the National

Committees in that sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

indicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject

of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62286 has been prepared by IEC technical committee 100: Audio,

video and multimedia systems and equipment.

This standard was developed by a project team of service and interface specialists within the

European Association of Consumer Electronics Manufacturers (EACEM). EACEM

subsequently merged with EICTA in September 2001. EICTA is the European Information,

Communications and Consumer Electronics Technology Industry Association.
The text of this standard is based on the following documents:
CDV Report on voting
100/432/CDV 100/493A/RVC

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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until

2005. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this standard may be issued at a later date.

INTRODUCTION

Consumer products are often repaired by service workshops who are servicing all kinds of

products developed by different manufacturers.

For high complexity products, the fault diagnosis becomes more and more difficult and time

consuming. To make diagnosis possible, manufacturers often develop some built-in diagnostic

software which can be used for fault finding together with an external diagnostic unit through

a Service Diagnostic Interface (SDI).

To avoid the need for a service workshop to purchase several different diagnostic units from

different manufacturers for different products, a standardized SDI is proposed for use by all

manufacturers and in all products in which such diagnostic interfaces are required. The result

will be that only one SDI is needed in the service workshops.

The SDI should also be suitable for diagnosis in a network (A/V or multimedia network) in

which different products from different manufacturers are connected together. The interface

should also allow for future development.
The standard SDI which has to be specified, should:
– be usable in future products;
– be easily connectable to a product or a network;
– be cheap;
– not limit product design.

SERVICE DIAGNOSTIC INTERFACE FOR CONSUMER
ELECTRONICS PRODUCTS AND NETWORKS –
Implementation for IEEE 1394
1 Scope

This International Standard specifies the requirements that have to be implemented in future

products that incorporate a digital interface, and service diagnostic software developed for

these products. The Service Diagnostic Interface (SDI) requires the use of a PC (desktop or

laptop) into which service diagnostic software can be loaded. A part of this PC software has to

be standardised while another part of this PC software is manufacturer/product related.

To reach a common approach in servicing all products from all manufacturers, it is necessary

to standardise specific items in the products (Device Under Test/DUT) as well as in the

diagnostic software on the PC.

The Service Diagnostic Interface (SDI) is based on the IEEE 1394:1995 specification because

this interface will be used in most future products. The use of this connection and existing

communication protocols enable implementation in products at low cost, and gives maximum

flexibility and efficiency.
The SDI consists of:
• Specific hardware and software requirements of the DUT.
• Specific requirements of the PC:
– the Service software,
– an IEEE 1394 interface (to be built in if not already present).
• The connection between the PC and the DUT.

This specification is a minimal specification necessary to be able to carry out computerised

diagnosis and covers the standardised software of the PC as well as the standardised

software and provisions in the DUT.

If an IEEE 1394 interface is present on the product, then the requirement for product

identification as described in this document (see 6.3) is mandatory. In addition, all

communication for any service application should go through the IEEE 1394 interface only, as

described in this document (in Clause 7).

3 Terms, definitions and abbreviations
3.1 Terms and definitions

For the purposes of this International Standard, the following terms and definitions apply.

3.1.1
configuration ROM

area of memory within an IEEE 1394-enabled device which holds specific information about

the device, as defined in IEEE 1212. Device information is held in a hierarchy of directories

within the ROM
3.1.2
EACEM unit directory
see unit directory
3.1.3
HW_Version
hardware version. IEEE 1212 optionally uses this to identify diagnostic software
3.1.4
instance directory

second level in the directory hierarchy. The instance directories provide a method to group

unit architectures (software protocols) to identify shared physical components. This directory

contains the offset into memory of various Unit directories, including the EACEM unit directory

3.1.5
IEEE 1394 repeater

another IEEE 1394 device in the network capable of relaying or repeating data. This device

may have more IEEE 1394 sockets and can provide a suitable connection into the system

3.1.6
Key_ID

Key IDentifier. IEEE 1212 use this to identify the contents of the remaining 3 bytes of a

quadlet in a directory. Key_ID is 6 bits long: the proceeding 2 bits are the type, which

identifies whether the data in the following 3 bytes is immediate (i.e. they contain the actual

data) or whether the 3 bytes are an offset to another place in memory
3.1.7
minimal ASCII

IEEE 1212 defines a limited set of Latin characters that can be used for text. The particular

set specified in SDI uses the 1 byte coding specified in IEEE 1212
3.1.8
model_ID

model IDentifier. IEEE 1212 optionally provide this to identify the model. The model should

represent a family or class of products and should not be unique to individual devices

3.1.9
multimedia
products or networks combining audio, video, computer and/or communication data
3.1.10
network
two or more CE (audio, video or multimedia) products connected together

3.1.13
root directory

the top level directory in the hierarchy of directories. This contains some basic information

about the device, such as the Vendor_ID, and also the offset into memory of the Instance

directory
3.1.14
unit directory

the third and lowest level in the hierarchy of directories. Each unit directory uniquely identifies

the software interface (unit architecture) used to control the unit. The EACEM Unit directory

provides additional information, either directly or indirectly, needed to specify locations used

in the SDI specification
3.1.15
Vendor_ID
vendor IDentifier. This is the RID for the vendor
3.2 Abbreviations

4 Different types of service diagnostics
4.1 Stand-alone products

In this situation, a connection is made between the diagnostic PC and the DUT, where the

DUT is from any manufacturer and of any type.
4.2 A/V or multimedia network

In this situation, a connection is made between the diagnostic PC and a network of A/V or

multimedia products.

In an A/V or multimedia network, several different products are interconnected and not all of

them are necessarily from the same manufacturer.

In this case, the SDI must be able to list the products on the network, detect which product is

causing a problem, and di
