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
product development of the second generation DVD video
player. This player forms the basis for future DVD
developments as described in the DVDv2 Overall Project
Management Plan.

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.

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):

1. 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.
2. The second line indicates the results of the shared SDRAM
Interconnection test.
3. The third line indicates the results ofthe shared SDRAM
read/write test.
4. The fourth line indicates what front panel processor was
connected to the monoboard. It could be one of the
following: SLAVE 2, SLAVE 3, SLAVE 4, or Not Detected.
5. The last line is the prompt asking the user to choose the
interface format. If the menu interface is chosen, the main
