the checking is suspended and the message is output for key entry.
Normally, all items are checked successively one after another au-
tomatically unless an error is found.

Selecting 2 and subsequent items executes respective menus and
outputs the results.
For the contents of each submenu, see “Check Items List”.

General Description of Checking Method
2.

(2-2) Revision

ROM revision number is displayed.-
Error: Not detected.
The revision number defined in the source file of ROM (At
the beginning of mass production, the Flash ROM of IC107
is used) is displayed with four digits.

(2-3) ROM Check Sum

Check sum is calculated.
Error: Not detected.
The 8-bit data are added at addresses 0x000F0000 ~
0x002EFFFF of ROM (IC107) and the result is displayed
with 4-digit hexadecimal number. Error is not detected.
Compare the result with the specified value.

(2-4) Model Type

Model code is displayed.
Error: Not detected.
The model code read from EEPROM (IC101) is displayed
with 2-digit hexadecimal number.

(2-5) Region

Region code is displayed.
Error: Not detected.
The region code determined from the model code is displayed.

(3-2) EEPROM Check

Data write 

→ read, and accord check

Error 03: EEPROM write/read discord
Data 0x9249, 0x2942, 0x4294 are written to addresses
0x00~0xFF of EEPROM (IC101), then read and checked.
Before writing, the data are saved, then after checking, they
are written to restore the contents of EEPROM.

(4-2) Servo DSP Check

Data write 

→ read, and accord check

Error 12: Read data discord
Data 0x9249, 0x2942, 0x4294 are written to the address
0x602 of RAM in the Servo DSP (IC302), then read and
checked.

(4-3) DSP Driver Test

Test signal data 

→ DSP Driver

Error: Not detected.
Caution: Do not conduct this test with a mechanical deck
connected.
The maximum voltage is applied to the Servo Driver IC
(IC401). If mechanical deck is connected, the motor and
optics could be damaged. Disconnect mechanical deck fol-
lowing the output message, then enter specified 4- or 5-
digit number from the remote commander, and press the

[ENTER]

. The test is conducted only when the input data

accord. Check the output level, then press the

>

to fin-

ish the test.
This test is skipped if “All” is selected.

Supplement: How to disconnect mechanical deck
Disconnect flat cables connected to the CN010 and CN015
of MB board. Also, disconnect harness from the CN203.

14

Caution: Do not conduct this check with a mechanical deck con-

nected.
An access is made to the stream supply and servo control
IC (IC302) and external RAM (IC303) using check data.
If mechanical deck is connected, the motor and optics
could be damaged. This check is also executed by the
“All” menu item.

Supplement: How to disconnect mechanical deck

Disconnect flat cables connected to the CN010 and
CN015 of MB board. Also, disconnect harness from
the CN203.

(5-2) ARP Register Check

Data write 

→ read, and accord check

Error 08: ARP register write, and read data discord
Data 0x00 to 0xFF are written to the TMAX register (ad-
dress 0xC6) in ARP (IC302), then they are read and checked.

(5-3) ARP to RAM Data Bus

Data write 

→ read, and accord check

Error 09: ARP 

←→ RAM data bus error

Data 0x0001 to 0x8000 where one bit each is set to 1 are
written to the address 0 of RAM (IC303) connected to the
ARP (IC302) through the bus, then they are read and
checked. In case of discord, written bit pattern and read
data are displayed. If data where multiple bits are 1 are
read, the bits concerned may touch each other. Further, if
data where certain bit is always 1 or 0 regardless of written
data, the line could be disconnected or shorted.

(5-4) ARP to RAM Address Bus

Data write 

→ other address read discord check

Error 10: ARP 

→ RAM address bus error

Caution: Address and data display in case of an error is

different from the display of other diagnosis (de-
scribed later).

Before starting the test, all addresses of RAM (IC303) are
cleared to 0x0000.
First, 0xA55A is written to the address 0x00000, and the
address data are read and checked from addresses 0x00001
to 0x80000 while shifting 1 bit each. Next, the data at that
address is cleared, and it is written to the address 0x00001,
and read and checked in the same manner. This check is
repeated up to the address 0x80000 while shifting the ad-
dress data by 1 bit each.
If data other than 0 is read at the addresses except written
address, an error is given because all addresses were al-
ready cleared to 0. In this check, the error display pattern is
different from that of other diagnosis; read data, written
address, and read address are displayed in this order. How-
ever, the message uses same template, and accordingly ex-
change Address and Data when reading. The following dis-
play, for example,

### Syscon Diagnosis ###

 5-4. ARP to RAM Address Bus

Error 10: ARP - RAM Address B

Address

: 0000A55A

Write Data : 00000000

Read Data

: 00080000

Press NEXT Key to Continue

Press PREV Key to Repeat

_

shows the data 0xA55A was read from address 0x00080000
though it was written to the address 0x00000000. This im-
plies that these addresses are in the form of shadow. Also,
if the read data is not 0xA55A, another error will be present.

(5-5) ARP RAM Check

Data write 

→ read, and accord check

Error 11: ARP RAM read data discord
The program code data stored in ROM are copied to all
areas of RAM (IC303) connected to the ARP (IC302)
through the bus, then they are read and checked if they ac-
cord. If the detail check was selected initially, the data are
written to all areas and read, then the same test is conducted
once again with the data where all bits are inverted between
1 and 0. If discord is detected, faulty address, written data,
and read data are displayed following the error code 11,
and the test is suspended.
