21、cing 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 togethe

22、r 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 product

23、s 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 int

24、erface 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. Page4 EN62286:2004SERVICE DIAGNOSTIC INTERFACE FOR CONSUMER ELECTRONICS PRODUCTS AND

25、 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

26、 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 necessar

27、y 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 exi

28、sting 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

29、 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 interfac

30、e 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). 2 Normative refer

33、1 Page5 EN62286:20043 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

34、, 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 hi

35、erarchy. 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

36、 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 lon

37、g: 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

38、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 multimed

39、ia 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 Page6 EN62286:20043.1.11 quadlet group of four bytes (32 bits). IEEE 1394 transmission is based on the transfer of quadlets and al

40、l data is quadlet-aligned 3.1.12 remote diagnosis diagnosis of product via telephone, internet, etc. 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 Ins

41、tance 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, need

42、ed 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 ASCII-1 American Standard Code for Information Interchange. This defines a set of Latin characters and control codes representing text.

45、 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 interco

46、nnected 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 diagnose the product concerned. 4.3 Remote diagnosis In addition to the configurations described above (stand

47、-alone product or network), a link can be made (for example via telephone, Internet, etc.) between the diagnostic PC in the workshop and a DUT/network at the customers home. Therefore, if a product has both an IEEE 1394 interface and a remote connection capability, this product should be able to tra

48、nsfer the diagnostic data, as described in this document, through the remote connection. It has to be specified how this type of communication is carried out, and which level of diagnosis will be possible. These items are not in the scope of this document, and will be defined later on. 5 Specificati

49、on of the SDI 5.1 General The SDI consists of: hardware and software, both in the DUT and in the test equipment (“tester”); the connection between the tester and the DUT. The total SDI can be divided into the elements specified in 5.2 and 5.3. 5.2 Hardware 5.2.1 Tester hardware requirements This can be a computer (for example desktop or laptop PC, MAC, or workstation) provided with at least one suitable IEEE 1394 in
