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.

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).

The first line indicates that the Diagnostic software has been
activated and contains the version number. The second line
lets the user choose the interface format. Enter 'C' to select
Command Mode and the next three lines are the successful
result of the two subsequent basic tests (nuclei 2, ,4 and the
detection of the display type used by the panel respectively). If
not all these messages appear on the terminal screen, then the
related nucleus found an error. The last line is the prompt
("DD>"). The diagnostic software is now ready to receive
commands.
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
