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.
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 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
Activation
Plug the recorder to the mains and the following text will appear
on the screen of the terminal (program):
DVD Video Recorder Diagnostic Software version 48
Basic SDRAM Data bus test passed
Basic SDRAM Address bus test passed
Basic SDRAM Device test passed
(M) enu, (C) ommand or (S) 2B-interface?
DD:>
051200
The first line indicates that the Diagnostic software has been
activated and contains the version number. The next lines are
the successful result of the SDRAM interconnection test and
the basic SDRAM test. The last line allows the user to choose
between the three possible interface forms. If pressing C has
made a choice for Command Interface, the prompt ("DD>") will
appear. The diagnostic software is now ready to receive
commands. The commands that can be given are the numbers
of the nuclei.
