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.

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):
DVDv6 Diagnostic Software version 7.03 S
(M)enu, or (C)ommand [M]:@ m <enter>
Press ENTER to go to Main Menu

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.
The term "DVDv6" implies that the DSW is running in the
ZiVA5 platform (6th generation).Interpretation of the DSW
version is done as follows:
