2.2 Error Handling
Each nucleus returns an error code. This code contains
six numerals, which means:
[ XX YY ZZ ]
The nucleus group numbers and nucleus numbers are the
same as above.
2.3 Command Mode Interface
Set-Up Physical Interface Components
Hardware required:
• Service PC
• one free COM port on the Service PC
• special cable to connect DVD recorder to Service PC
The service PC must have a terminal emulation program
(e.g. 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 recorder. 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
(AAX57390)

In this case, the boot EEPROM of the Chrysalis Digital
Board does not contain the required string with the
hardware information. To update the Digital Board with the
correct string, nucleus 1226 must be executed.
Before doing so, one must generate this string. In order to
generate the correct parameters, an MS Windows utility,
called "dbstring.exe", is available (contact your Philips
regional service support for this). For a detailed
description, see next section 'String Generation'.

4. Browse to the directory with the Diagnostics software
(e.g. type 'cd c:\ds\'), and execute the 'dbstring.exe'
application.
