Alignment of ‘Slash information’ (or slash version)
When PCB02, Digital is replaced, it is necessary to align the slash version. The slash
version is unique for DVD 2, and can be regarded as a initialization. The slash
version for DVD 2 is 11221, and is stored in NVM (item 7809) on PCB02, Digital.
For alignment the following procedure must be followed:
1. Start HyperTerminal.
2. Connect DVD 2 (P1103) to a COM port (use USB/COM converter if no COM port
is available).
3. Power on DVD 2 and confirm that ‘Diagnostic info.’ appears on screen.
4. Type in command promt line DS:> 1217 11221. Screen shows.
DS:> 1217 11221
121700:
Test OK @
The alignment can be confirmed by typing at promt DS:>1218, e.g.
DS:> 1218
121800: The slash version is = 11221
Test OK @
Alignment of ‘IEEE unique number’
The IEEE unique number can be regarded as the serial number of the hardware
(PCB02, Digital), and is placed in NVM (item 7809) on PCB02, Digital.
In case of failure PCB02, Digital is replaced by an empty device. After replacement
of the NVM, DVD 2 can only startup in Diagnostic software mode because the
Slash version is not in place.
By way of commands via the Diagnostic Software (DS) and hyperterminal
connection to the PC, these factory settings must be restored in the NVM. The
number is a 10-digit hexadecimal number.
In most cases it is possible to read out the IEEE unique number from the defective
PCB02, Digital, and in that way easy to copy it into the replaced part.
For alignment follow this procedure:
1. Start HyperTerminal.
2. Connect DVD 2 (P1103) to a COM port (use USB/COM converter if no COM port
is available).
3. Power on DVD 2 and confirm that ‘Diagnostic info.’ appears on screen.
4. Type in command promt line DS:> 1207 [IEEE number].
Example of the screen information:
DS:> 1207 3E5CE929C4
120700:
Test OK @
DVD 2 now has its original IEEE unique number
