DIN EN 62394:2018-07

This International Standard specifies requirements for service diagnostic software to be implemented in products that incorporate a digital interface. It does not specify requirements for carrying out remote diagnosis or for manufacturer-dependent software. The SDI (Service Diagnostic Interface) requires an external controller (exclusive or general-purpose/PC) into which service diagnostic software can be loaded. Part of the controller software should be standardized while another part of this controller software should be unique to the manufacturer. To reach a common approach in servicing all products from all manufacturers, it is necessary to standardize specific items to be tested in products and in controllers' diagnostic software. The SDI is based upon the ECHONET specification version 2.11, ECHONET Lite specification version 1.01 and APPENDIX Detailed Requirements for ECHONET Device objects Release B because this interface will be used in future products. The use of this connection and existing communication protocols enable implementation in products at low cost, with maximum flexibility and efficiency. The SDI consists of - specific hardware and software requirements of the device under test (DUT); - specific requirements of the controller: - the service software; - an ECHONET interface; - the connection between the controller and the DUT. The responsible committee is DKE/K 742 "Audio-, Video- und Multimediasysteme, -geräte und -komponenten" ("Audio, video and multimedia systems, equipment and components") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
