– 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 the formula below:
35828*YEAR + 676* WEEK + 26*V + N+ 8788
The figures are fixed, YEAR + WEEK + factory code ( V+
N) are variable
Example: 35828*01+676*36+26*22+14+8788 = 69538
(decimal)
Then we translate the decimal number to a hexadecimal
number. example: 69538 (decimal)= 10FA2 (hex)
4. Last 5 numbers: The last 5 numbers exist out of the Lot and
SERIAL number according formula below:
serial nr + 1 * 100000
Example: 100000 = 230156 (decimal)
230156 (decimal) = 3830C (hex)
5. Program new digital board via nucleus or 1207. Therefore
we use the 10 hexadecimal numbers we calculated above:
example:
>1207 10D7A3830C
12700: Test OK @
The set has now its original unique number
8.4 Alignments after replacing the Boot EEPROM
7810 in sets with Digital Board Chrysalis
The NVM, item 7810, on the Digitalt Board Chrysalis contains
the “Diversity String” that tells the software during startup which
hardware version is present.
The setting is stored in the NVM during the production of the
Digital Board Chrysalis
In case of a fault the NVM must be replaced by a programmed
device containing the boot script.
Via the Diagnostic Software the Diversity String is stored with
command 1226, followed by the Diversity String as parameter.
The diversity strings used in DVDR77/0x1 are the following:
ChrysalisString
