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) 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 nr. PC interface cable: 3122 785 90017

Activation

Switch the player on and the following text will appear on the
screen of the terminal (program):

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 next three lines
are the succesful result of the subsequent basic tests (nuclei 2,
3, 4 and initialisation of Karaoke chip respectively). If not all
these messages appear on the terminal screen, then the
related nucleus found an error. The last line is the prompt
asking to choose for an interface form. If a choice for Menu
Interface has been made, the main menu will appear. For the
layout of the menus, see page 25.
To switch between interfaces, the DVD player needs to be
switched off and on again.
Note1 : The DVDv2B player has no power-ON key, but should
be turned on by connecting the power-cable.
Note2 : The Dram tests are no longer executed because the
player has no DRAM .
Note3 : When the stack is located in the internal memory, the
test with the SRAM doesn't work and will be left out.
Note4 : The karaoke initialisation will also take place if there is
no karaoke-chip in the player.

Usage

A selection can be given by the user by typing the number of
the menu-item chosen at the prompt. Each entry must be
terminated with a . Invalid selections will cause an error
message by the Menu Handler. Example:

Result and output of an activated (and terminated) nucleus will
be sent back to the service terminal. Example:

After the user presses a key, the current menu is rebuilt on
screen.
Pressing < return > at the prompt without any further input at
the terminal will always rebuild the main menu.

Termination

The menu interface is terminated by switching off the DVD
player.
