5.7 Diagnostic Software Description
5.7.1 Introduction
Purpose
This document describes all interfaces from the outside world
to the diagnostic software, what is needed to use these
interfaces and how to access them.
Scope
This document has been realised within the framework of the
DVD video player.
5.7.2 Definitions and Abbreviations
Definitions
Control PC
Automatic test equipment, part of the
production control system in the
factory, to control the execution of
Diagnostic Nuclei in the DVD player.
Diagnostic Nucleus Part of the Diagnostic Software. Each
nucleus contains an atomic and
software independent diagnostic test,
testing a functional part of the DVD
player hardware on component level.
Script Part of the Diagnostic Software. Each
script contains a sequence of
Diagnostic Nuclei to be executed.
Service PC PC used by a service- or repair-person
to communicate with the Diagnostic
Software in the DVD player.

5.8 Overview of Interfaces
The table below shows an overview of the user interfaces of the
Diagnostic Software. The table is based on logical interface,
interfaces as seen from user perspective. A logical interface
can use one or more physical interface components. The DVD
has only a single RS232 port, implying that all interfaces using
this port are mutually exclusive.
Table 5-25 Interface overview
• In the next chapters the logical user interfaces are
described in more detail including the exact use of the
physical interface components.
5.9 Description of Interfaces
5.9.1 Menu Interface
The menu interface is part of the Level 2 / Second Line
diagnostic mode. Via the menu interface it is possible to control
the execution of the Diagnostic Nuclei.
Set-up Physical Interface Components
Hardware required:
•
Service PC
• one free COM port on the Service PC
• special cable to connect DVD player to Service PC
The service PC must have a terminal emulation program (e.g.
OS2 WarpTerminal or Procomm /Windows Hyperterminal)
installed and must have a free COM port (e.g. COM1). Activate
the terminal emulation program and check that the port settings
for the free COM port are: 19200 bps, 8 data bits, no parity, 1
stop bit and no flow control. The free COM port must be
connected via a special cable to the RS232 port of the DVD
player. This special cable will also connect the test pin, which
is available on the connector, to ground (i.e. activate test pin).
Activation
Switch the player on and the following text will appear on the
screen of the terminal (program):
Figure 5-36
• The first line indicates that the Diagnostic software has
been activated and contains the version number of the
diagnostic; this is also an indication that the first basic
nucleus (nucleus number 1) has been executed
succesfully.
• The term "DVDv6" implies that the DSW is running in the
ZiVA5 platform (6th generation).Interpretation of the DSW
version is done as follows:
