12、nostic software consists of:- Service PC, a personal computer with a terminal emulation program that emulates a simple ASCII terminal.The Service PC is connected to the RS232 port of the DVD player and is used for Level 2 / Second Linediagnostic mode. The Service PC is operated by a service personne

15、hardware which is subject to the Diagnostic Software.The DVD has only one single RS232 port, implying that all interfaces using this port are mutually exclusive.The Full Diagnostic Software (FDS) is aimed to support service and repair and can present menus and receivecommands via a Service PC.The Di

16、agnostic Software contains a large number of tiny Diagnostic Nuclei. Each nucleus contains an atomic andsoftware independent diagnostic test, testing a functional part of the DVD player hardware on component level.Each Diagnostic Nucleus works directly on the DVD player hardware, no drivers will be

17、used. Each DiagnosticNucleus returns a Result indicating if and which error was detected (e.g. faulty SDRAM chip).It is possible to combine these diagnostic nuclei in a Script to create a high level test like a player test, a script canbe as simple as a sequence of executed Diagnostic Nuclei. The Di

18、agnostic Software contains standard scripts fordealer and player test. Each script returns a Result indicating if and which error was detected (e.g. faulty module).3-1During power-on the Selector (part of the DVD boot sequence) will check the presence of certain triggers (signalon Test Pin, key comb

The scriptactivation keys vary depending on the model used.This test consists of running a predefined script (Dealer Test Script). The script controls the execution of a numberof dia

At the end of the script one message is returned indicat-ing if a failure in the DVD player is detected or not. The message will be displa
