1-7-2. Precaution on Replacing the VC-41 Board

The following data need to be written on a brand-new board for repair because the board has no information that is unique to a
model.
Note
The [LOAD AND WRITE] function in "ADJUSTMENT DATA BACKUP" on the DATA tab in the Adjust Manual overwrites all
data of the unit. Therefore execute the [LOAD AND WRITE] before performing the following operation.
Destination Data
The destination data stored in the board for repair is different from the destination setting stored in the board before replacement in
some cases.
When the board has been replaced with a board for repair, be sure to set the destination.
Method of the destination data write:
Start the Adjust Manual in the Adjust Station and execute the "Destination data write" on the ADJUST tab.
Restore Data
Before replacing the board with a brand-new board, be sure to extract the data from the former one.
The following kinds of data are acquired by the unit.
• Product ID & USB Serial Data
• EVF Brightness and White Balance Data
• WB Adjustment Data
Method of the data extracting:
Start the Adjust Manual in the Adjust Station and execute the "RESTORE DATA" on the DATA tab.
USB Serial No. and Product ID
The unit is shipped after an ID (USB Serial No.) unique to each unit and an ID (Product ID) unique to each model have been written.
These IDs have not been written in a brand-new board. Therefore, after the board has been replaced, be sure to write these IDs to a
brand-new board.
Method of the ID writing:
• When ID is readable
When the unit before repair can be turned on and ID adjustment values can be read using the Adjust Manual, perform the
following work.
Work:
1. Execute [Read and Save] of "RESTORE DATA" in the DATA tab.
2. After replacement with the repair VC board, execute [LOAD and WRITE] of "PRODUCT ID & USB SERIAL No.
INPUT" in the ADJUST tab of the Adjust Manual to write extracted data to the unit.
• When ID is unreadable
When ID adjustment values cannot be read, perform the following work.
Work:
After replacement with the repair VC board, start the Adjust Manual from the Adjust Station and execute "PRODUCT ID &
USB SERIAL No. INPUT" to enter ID.
