8. Alignments & Test Procedures
8.1. Reprogramming Procedure of NVM on the
Digital Board
The NVM, item 7809 on the Digital board contains the
following:
•
Slash information (or slash version)
•
IEEE Unique number
The slash version and IEEE Unique number are stored at the
end of the production line of the set.
In case of failure the NVM is replaced by an empty device.
After replacement of the NVM the set can only startup in
Diagnostic software mode because the Slash version is not in
placed.
By way of commands via the Diagnostic Software (DS) and
hyperterminal connection to the PC, these factory settings
must be restored in the NVM.
8.1.1. Slash Version
The slash version is stored with DS command 1217 followed
by the slash version as parameter.
The slash versions used in DVDR9000H families are as
follows:
•
DVDR9000H/10: 11205
•
DVDR9000H/75: 11220
•
DVDR9000H/97: 11219
Example:
DS:> 1217 11201
With DS command 1218 the slash version can be displayed
8.1.2. IEEE Unique Number
1. Note the serial number of the set example:
VN050136130156
- VN = production center (VN....Szekesfehervar).
According to UAW-500: V=22 and N=14
- 05 = change code (this is not used for this
calculation)
- 01 = YEAR
- 36 = Production WEEK
- 130156 = Lot and SERIAL number
2. Calculate the unique number: this number always exists
out of 10 hexadecimal numbers
3. First 5 numbers: First we calculate a decimal number
according to formula below:
- 35828*YEAR + 676*WEEK + 26*A + H + 8788
- The fi gures are fi xed, YEAR + WEEK + production
center code (A + H) are variables
- Example: 35828*01 + 676*36 + 26*1 + 8 + 8788 =
68986 (decimal)
- Then we translate this decimal number to a
hexadecimal number.
- Example: 68986 = 10D7A (hex)
4. Last 5 numbers: The last 5 numbers exist out of the Lot
and SERIAL number.
We have to translate the decimal number to the next 5
hexadecimal numbers:
Example: 130156 (decimal) = 1FC6C (hex)
5. This IEEE Unique number (10-digit hexadecimal number)
is stored with DS command 1207.
Example:
DS:>1207 10D7A1FC6C
120700: Test OK@
The set has now its original IEEE unique number.
With DS command 1208 the slash version can be displayed.

Reprogramming Procedure of NVM on the
Digital Board
The Boot Eeprom, item 7810 on the Digital board contains the
"Diversity String" that tells the software during startup which
hardware version is present. This setting is stored during the
production of the Digital board.
In case of failure the Eeprom must be replaced by a
programmed device containing the boot script.
Via the Dignostic Software the "Diversity String" is stored
with the command 1226, followed by the "Diversity String" as
parameter.
The Diversity strings used in DVDR9000H/10 are as follows:
DVDR9000H/10:
4442484973EF40014630355F3300000049040300000101020

000000010002010000000000000000
Example:
DS:> 1226
4442484973EF40014630355F3300000049040300000101020
00101004008080044564452323030312E3030310102020808
000000010002010000000000000000
Test OK @
With DS command 1229 the settings can be displayed.
Laser Control Adjustment
In case of exchanging DVD-M or Frontend Board (PCBA
of the Basic Engine) an adjustment to align the OPU and
Frontend Board to each other is necessary.
This adjustment is done with the DSW software nucleus 931.
The adjustments takes about 30 seconds and the data is
stored in the OPU Eeprom.
Example:
DS:> 931
93100
Test OK @
Procedure for formatting a new HDD:
In case of failure the HDD is replaced by a new unformatted
HDD.
To prepare the new HDD for use it must be formatted with a
Master DVD via the Diagnostic software nucleus 2107.
Example:
DS:> 2107
Please insert the Master DVD <OK>
Executing transfer table 1 of 4........
Please wait... <OK>
210700: Transfer OK
Test OK @
