Data Communication Interfaces
Communication between the CDR recorder and the PC is
straightforward: everything the CDR recorder transmits to the
PC is shown on the PC screen. Data, transmitted from the PC
to the CDR775, is treated as a choice from the currently shown
menu.
All functionality of the MDD has to be part of the CDR775
software; the PC can only use a terminal emulation program.
Menu Structure and Test Results
This chapter describes the structure of the menus and the
results of the tests, as shown on the PC screen.
Menu Structure
When starting up, the PC screen is cleared and the software
version and the main menu (level 1) are shown. From the main
menu, one of the sub menus (level 2) can be selected. These
sub menus contain other sub menus and/or a number of tests
that can be executed. The menus are shown below. '>>'
indicates that when this option is selected, a new menu will be
shown.
Level 1 Mainmenu:

4 Playback module test >>* *Only used for the CDR775

When a test is running, a 'test running indicator' (a dot) is
showed on the screen every second, When a test has been
executed, the screen is cleared and the result of the test (if any)
and the menu, separated by one empty line, are showed.
Three types of tests exist:
Tests that return PASSED or FAILED, like the DRAM test.
When a test has been executed, the result is showed on the PC
screen;
Tests that return a value, the message 'PASSED, xxx' (with xxx
is the returned value) is showed on the PC screen;
Tests that don't return anything, like the 'laser on' test. Most of
these tests require a visual check of the service person. When
one of these tests is executed, 'PASSED, visual check' is
showed on the PC.
Level 2 menus
When a submenu is selected in the main menu, the level 2
menus are showed . These sub menus contain other sub
menus and/or a number of tests that can be executed.
