5.7.1Layout 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@

5.7.2Command Mode Interface

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 description of the nucleus.

Note: User confirmation is necessary during front panel tests
