Firmware Upgrading & Diagnostic Software
Diagnostic Software
Due to the complexity of the DVD recorder, the time to find a
defect in the recorder can become long. To reduce this time,
the recorder has been equipped with Diagnostic and Service
software (DS). The DS offers functionality to diagnose the
DVDR hardware and tests the following:
•
Interconnections between components
•
Accessibility of components
•
Functionality of the audio and video paths
This functionality can be accessed via several interfaces:
1.
End user/Dealer script interface
2.
Command Interface
The End user/Dealer script interface gives a diagnosis on a
stand alone DVD recorder. During this mode, a number of
hardware tests (nuclei) are automatically executed to check if
the recorder is faulty. The diagnosis is simply a "fail" or "pass"
message. If the message "FAIL" appears on the display, there
is apparently a failure in the recorder. If the message "PASS"
appears, the nuclei in this mode have been executed
successfully. There can be still a failure in the recorder
because the nuclei in this mode don't cover the complete
functionality of the recorder.
Figure 5-1
The End use/Dealer script executes all diagnostic nuclei that
do not need any user interaction and are meaningful on a
standalone DVD recorder.
