Layout of Results Diagnostic Nuclei
Results returned from a Diagnostic Nucleus will be displayed in
the following layout:
< number >< string > [ok | ER]
< number >: is a 4-digit decimal number padded with leading
zeros if its value is less than 4 digits. The first 2 digits identify
the generating nucleus (or group of nuclei) while the latter 2
digits indicate the error number.
< string >: is a text string containing information about the result
of the Diagnostic Nucleus.
< number > and < string > are defined in [SSD_DN] in the
output sections of each Nucleus.
Examples:
1. 0001Unknown command ER @
2. 3100OK @
3. 0901Data line X is not connected to the DRAM ER@

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) 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).
Code number of PC interface cable: 3122 785 90017
Activation
Switch the player on and the following text will appear on the
screen of the terminal (program):
DVDv2 Diagnostic Software version 1.7
SDRAM Interconnection test passed
Basic SDRAM test passed
(M) enu, (C) ommand or (S) 2B-interface?
DD:>
Figure 5-37
The first line indicates that the Diagnostic software has been
activated and contains the version number. The next lines are
the successful result of the SDRAM interconnection test and
the basic SDRAM test. The last line allows the user to choose
between the three possible interface forms. If pressing C has
made a choice for Command Interface, the prompt ("DD>") will
appear. The diagnostic software is now ready to receive
commands. The commands that can be given are the numbers
of the nuclei.
Command Overview of Nuclei
The following table gives an overview of all available nuclei.
The first column contains an identification number, the second
contains the name of a nucleus and the last column indicate the
description of the nucleus.
Note: User confirmation is necessary during front panel tests
