8. Alignments and Test Procedures
8.1
Reprogramming Procedure of NVM on the FEBE
board
The NVM, item 7905, on the FEBE board contains the slash
information of the set
The slash version is stored at the end of the production line of
the set.
In case of failure, the NVM must be replaced by an empty
device. By way of commands via the Diagnostic Software or via
ComPair, the factory settings must be restored in the NVM.
8.1.1 Slash Version
The slash version is stored with command 1217 followed by the
slash version as parameter.
The slash versions used in DVDR615 are as follows:
• DVDR615/69:
Example:
DD:>1217 13010
8.2 Rework Procedure IEEE Unique Number
8.2.1 Scope:
The procedure describes how to upgrade sets with a unique
number after repair. This unique number is stored in the
NVRAM (item 7001) of the FEBE board at the end of the
production line.
This procedure is only valid or necessary when:
• The FEBE board is replaced
• NVRAM on the FEBE board is replaced
• NVRAM is cleared
In all other cases the repaired set retains its unique number.
The procedure defines several means to re-assure the unique
number depending on the possibilities of repair or the state the
faulty set is in.
8.2.2 Handling:
State of original (defective) board:
1. The FEBE board starts up in Diagnostics Mode: follow
procedure A to retrieve the valid unique number
2. The FEBE board does NOT start up in Diagnostics Mode:
follow procedure B.
8.2.3 Procedure A
1. Connect defective digital board to PC via serial cable (3122
785 90017)
2. start up hyper terminal or any other serial terminal via the
correct settings (DSW command mode interface)
3. read out existing unique number via 1208
example:
DS:> 1208 120800: DvldNumber is: 0x0C22384E5A
Test OK @
4. note read out
5. program new digital board via nucleus 1207
example:
DS:> 1207 1234567890 120700: Test OK @
The set has now the original unique number
8.2.4 Procedure B
1. Note the serial number of the set example:
VN050136130156
– VN = production centre (VN....Szekesfehervar).
According to UAW-500: V=22 and N=14

Alignments and Test Procedures
13010
DVDR615/69
– 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 1207. Therefore we
use the 10 hexadecimal numbers we calculated above:
example:
DS:>1207 10D7A1FC6C
120700: Test OK @
The set has now its original unique number
8.3 Alignments after replacing the Boot EEPROM
7904 on the FEBE Board
The NVM, item 7904, on the FEBE Board 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
FEBE Board.
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 DVDR615 are as follows:
FEBE String
Board
Type:
E1_AV3_4 444248495AB8200145315F4156335F34350
40300000101020001000020040000
Example:
DS:> 1226 444248495AB8200145315F4156335F34350
40300000101020001000020040000
122600
Test OK @
E2_AV3_4 FEBE Board (for DVDR615/69).
With command 1228 the settings can be displayed.
8.4 Adjust Laser Control
In case of exchanging DVD-M or PWB an adjustment to align
OPU and PWB to each other is necessary.
8.4.1 Adjustment Procedure
– Connect the Digital Board to a PC via serial cable (3122
785 90017)
– Start up Hyperterminal or any other terminal program with
the correct settings (19200 8-N-1)
