[How to acquire various data]
• Commands for acquiring various durations of the drive
Use the LogSense command.
If "PKT:4D 00 70 00 00 00 00 00 20 00 00 00" is issued, the following data are stored in the Read buffer:
<How to read the data in the Read buffer>
Accumulated power-on duration of the drive : data [8]-[11] (Most Significant Byte: data [8], Least Significant Byte: data [11])
LD read power-on duration for the DVD
LD read power-on duration for the CD
LD read power-on duration for the BD
The unit for accumulated power-on duration is 2 minutes.
The format for duration indication is "hours:minutes."
• Commands for acquiring the PU serial No.
Use the "Read Buffer" command.
If "PKT:3c 02 A0 00 ∗∗ ∗∗ 00 00 02 00 00" (∗∗ ∗∗: Read address) is issued, part of the PU serial number can be confirmed
at data [0]/data [1] of the Read buffer. (Most Significant Byte: data [1], Least Significant Byte: data [0])
Enter the following address in the read address (∗∗ ∗∗) to acquire drive serial data:
Most Significant
Read address: 0x104,
Display the acquired serial No. in decimal notation.
[E.g.]
Acquiring data for 0x104:
PKT:3c 02 A0 00 01 04 00 00 02 00 00 00
data[1] = 0x00 , data[0] = 0x01
Acquiring data for 0x106:
PKT:3c 02 A0 00 01 06 00 00 02 00 00 00
data[1] = 0x28 , data[0] = 0x7A
PU serial No.: 0x0001287A ––> 00075898
