7.1.9 REWRITING OF THE GUIDS
GUID label
RS-232C cable
DVD interface
jig (GGF1348)
CN2405
PCIB ASSY
SIDE B
Notes:
• Because the GUIDs are written on the PCIB Assy before shipping, rewriting of the GUIDs is not necessary when replacing
the PCIB Assy.
• When IC2406 (PD6453D8) on the PCIB Assy is replaced, rewriting of the GUIDs is required.
Procedures:
1. Take note of the numbers written on the GUID label stuck on the PCIB Assy.
2. Install the PCIB Assy in the unit. Connect the COM port of your PC and CN2405 on the PCIB Assy, using the DVD
interface jig (GGF1348).
Format of the GUID label (for reference)
The IEEE1394 Interface is mounted in the unit, and the
EUI-64 codes are written in the flash ROM (IC2406) on
the PCIB Assy. On the GUID label, this content is described.
1. Printing format
Label: The part No. of the label is VRW1877.
Print color: Black
Printed content: Barcode: CODE128
Numerics: GUID serial No. (last 7 digits)
2. Relationship between the ID of the Assy and the serial
number
The values written on the Assy are the ID of the product
(0x015) and the GUID serial No. specific to each product.
The relationship between these numbers and the serial
numbers printed on the label is as shown below:
3. Turn the unit on. After the unit starts up, enter "/15
∗∗∗∗∗
/SW" from the PC then press [ENTER] key to send the command
("
∗∗∗∗∗
" stands for a specific GUID).
Note:
The value written on the GUID label is in decimal notation and must be converted to hexadecimal for writing a
command. For details, see "Format of the GUID label."
4. Enter "SR" from the PC then press [ENTER] key to send the command.
As "GUID: 15
∗∗∗∗∗
" is displayed, check that this value is the same as that entered in Step 3.
When rewriting the GUIDs, connect the COM port of your PC and the connector for servicing mounted on the PCIB Assy of
the unit.
For transmission of commands, use general-purpose RS-232C communication software.
Communication settings are as follows:
Bit rate
: 57600 bps
Data bits
: 8
Parity
: None
Stop bit
: 1
Flow control : None
Two digits at the
beginning: 00
Last 7 digits: GUID serial No.
(0000001-1048575)
