1-2. PRECAUTION ON REPLACING THE VC-618 BOARD
Note the following when replacing the board.
Destination Data
When you replace to the repairing board, the written destination data of repairing board also might be changed to original setting.
Start the Adjust Manual in the Adjust Station and execute the “DESTINATION DATA WRITE”.
Start the Adjust Manual in the Adjust Station and execute the “DESTINATION DATA WRITE”.
USB Serial No.
The set is shipped with a unique ID (USB Serial No.) written in it.
This ID has not been written in a new board for service, and therefore it must be entered after the board replacement.
Start the Adjust Manual in the Adjust Station and execute the “USB SERIAL No. INPUT”.

Start the Adjust Manual in the Adjust Station and execute the “USB SERIAL No. INPUT”.
Product ID
The unit is shipped after an ID (PRODUCT ID) unique to each model has been written.
This ID is not written to a new replacement board. Enter a unique ID after the board has been replaced.
Start the Adjust Manual in the Adjust Station and execute the “PRODUCT ID & USB SERIAL No. INPUT”.
This ID is not written to a new replacement board. Enter a unique ID after the board has been replaced.
Start the Adjust Manual in the Adjust Station and execute the “PRODUCT ID & USB SERIAL No. INPUT”.
Setting PRODUCT ID
No PRODUCT ID is set for a new replacement board.
Therefore, if the board is replaced with a new replacement board, a discrepancy with the user-registered PRODUCT ID provided by the customer
may be generated.
After the board has been replaced with a new replacement board, start Adjust Manual from Adjust Station and execute “PRODUCT ID & USB
SERIAL No. INPUT”.
Therefore, if the board is replaced with a new replacement board, a discrepancy with the user-registered PRODUCT ID provided by the customer
