BS EN 62286:2004 – 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 1 394:1 995 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 1 394 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 1 394 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 1 394 interface only, as described in this document (in Clause 7).
