DEBUGGING SCREEN SPECIFICATION FOR THE MECHANISM CONTROLLER
3
Indication Contents
1. The error that became the trigger that an error of 2
occurred.
There are many cases same as 2.
2. The error number that transferred to the system
controller
Refer to the error list about contents of error number.
3. Code read in state
(it does not support in this unit)
When X is indicated, ID or subcode are not able to read in.
When X is not indicated, they are able to read in.
4. ID or subcode
(it does not support in this unit)
Subcode indicates the A time.
5. Inside mode of the mechanism controller when an error
of 1 occurred
It can indicate to a maximum 10 mode. Indicate it in order of
an old mode from the left, and go right, and become a new
mode. Indicate only a nest share of the mode.
6. Processing step of inside mode of 5
It can grasp the mode reaching an error and transition of step
by watching 5 and 6 and it can specify the occurrence place of
most errors.
7. Disk information in the mechanism controller
? : Indistinctness
NO : There is no disc
DVD 1 : DVD single layer
DVD 2 : DVD dual layer
CD
: CD
CDR : CD-R or CD-RW
CDR P : PRD of CD-R or CD-RW
8. As a result of 8cm /12cm distinction
? : Indistinctness (undistinction)
8 : 8 cm
12 : 12 cm
9. OEIC gain
(it does not support in this unit)
H : OEIC HIGH gain
L : OEIC LOW gain
10. SGC gain for LD of 780nm
It indicates a step using in the mechanism controller inside
with a hexadecimal number.
Set the gain so that S curve becomes 1.8V (p-p) in disc
distinction.
11. SGC gain for LD of 650nm For L0.
It indicates a step using in the mechanism controller inside
with a hexadecimal number. Set a gain so that S curve
becomes 1.8V (p-p) in disc distinction.
12. SGC gain for LD of 650nm For L1.
It indicates a step using in the mechanism controller inside
with a hexadecimal number. Set a gain so that a S curve
becomes 1.8V (p-p) in disc distinction.
13. RF count value for disc distinction
RF count value to use the disc distinction. It compares
threshold value of 14 and 15 and distinguishes the disc.
14. Disc distinction threshold value (DVD and CD)
Threshold value of the disc distinction. Distinguish it from
DVD if bigger than this value, and distinguish it from CD if
small.
