CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTION

2 – 36

When an error massage is indicated on the display, check the following

items. 

• When “Command Sending Retry Error” and “Nothing Received” are

displayed:

Check to confirm that the PC and the information display are prop-

erly connected with the RS-232C cable. 

•  When “COM Port Open Error” is displayed:

Check to confirm that the set COM Port is not used by another tool. If it

is used by another tool, terminate the tool, and execute the procedures

again. 

Temperature monitor might not operate for some reason if other appli-
cation is active.

Please use this tool while activated as much as possible.

The following information as well as user setting information are saved

to the EEPROM (IC402, 404) of the main unit. 

(3 and 4 are information linked with the panel.)

1 MODEL NAME

2 SERIAL NUMBER

3 USAGE TIME

4 WHITE BALANCE SETTING VALUE

5 CALIBRATION SETTING VALUE

6 TEMPERATURE MONITOR SETTING INFORMATION

Therefore, when the PWB, the panel, IC402, or IC404 is replaced, ini-
tialization and setting must be performed according to necessity. 

In addition, after completion of the work, perform ALL RESET.

1 MODEL NAME

The model name must be set depending on the destination. 
For setting procedures, refer to “8. MODEL NAME SETTING PRO-

CEDURES”. 

2 SERIAL NUMBER

The machine has its own serial number which is described on the
nameplate at the back of the machine. 

For setting procedures, refer to “6. SERIAL NUMBER WRITING

PROCEDURES”.

3 USAGE TIME

This information is linked with the panel. When replacing the PWB,

read the information before replacement, and write it to the new

PWB after replacement.
For setting procedures, refer to “7. USAGE TIME SETTING PRO-

CEDURES”. 

4 WHITE BALANCE SETTING VALUE

This information is linked with the panel. When replacing the PWB,

read the information before replacement, and write it to the new

PWB after replacement. 

Execute resetting when the panel is replaced.

For setting procedures, refer to “3-5. WHITE BALANCE SETTING

PROCEDURES”.

5 CALIBRATION SETTING VALUE

Since a service part PWB has been adjusted, there is no need to

set when replacing the PWB.

Setting may be required depending on the changed part.

For setting procedures, refer to “3-2. CALIBRATION”.

6 TEMPERATURE MONITOR SETTING INFORMATION

This is the setting information related to temperature watch.

Execute resetting when replacing the PWB or the panel. 

For setting procedures, refer to “9.TEMPERATURE MONITOR

SETTING PROCEDURES”. 

1) Read the following information from the monitor before replacement

of the PWB.

1 USAGE TIME

2 WHITE BALANCE VALUE

*If the machine does not operate before replacement and reading

cannot be made, this procedure is not required. 

2) Replace the PWB and execute FACTORY RESET.

(Refer to “3-3. FACTORY RESET”.)

3) Write data into EDID.

(Refer to “5. EDID WRITING PROCEDURES”.)

4) If necessary, update the firmware.

(Refer to “4. FIRMWARE UPDATE PROCEDURES”.)

5) Set the MODEL TYPE depending on the destination.

(Refer to “MODEL TYPE” in “3. SERVICE MENU”.)

6) Set the MODEL NAME depending on the destination.

(Refer to “8. MODEL NAME SETTING PROCEDURES”.)

7) Write the information read in the above step 1).

*When reading cannot be made in the step 1):

• Set “0” to USAGE TIME and perform initialization. 

• Reset the WHITE BALANCE set values. 

8) Write the serial number.

(Refer to “6. SERIAL NUMBER WRITING PROCEDURES”.)

9) Reset the temperature watch setting information.

(Refer to “9. TEMPERATURE MONITOR SETTING PROCE-

DURES”.)

1) Set “0” to USAGE TIME and perform initialization. 

2) Reset the WHITE BALANCE set values. 

3) Reset the temperature watch setting information.

(Refer to “9. TEMPERATURE MONITOR SETTING PROCE-

DURES”.)

(Refer to “7. USAGE TIME SETTING PROCEDURES”.)

•  PC which is installed Windows 2000/XP OS and has COM port.

•  RS-232C cable (Female-Female, Straight)  

•  Information Display which has the Logging function.

Connect PC’s COM port and Information Display’s RS-232C input con-

nector with RS-232C cable.

Execute “InfoDispReport.exe”, then following window appears.

Select “COM Port” as you connected to PC, and push “Get Logs” but-
ton.

Then, following window appears. The bar progresses, if it communi-
cates well.

If following window appears, it failed to communicate. Then, check the
