3.4 Procedure B
1. Note the serial number of the set example:
AH050136130156
– AH = production centre Hasselt. According to UAW-
500: A=1 and H=8
– 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 the formula below: 35828*YEAR + 676*
WEEK + 26*A + H + 8788 The figures are fixed, YEAR
+ WEEK + factory code ( A + H) are variable
Example: 35828*01+676*36+26*1+8+8788 = 68986
(decimal) Then we translate the decimal number to a
hexadecimal number.
example: 68986 (decimal)= 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. Program new digital board via nucleus 410 Therefore
we use the 10 hexadecimal numbers we calculated
above:
example:
DD:> 410 10D7A1FC6C
41000:
Test OK @
The set has now its original unique numbe
