3-1

When you replace to a board for service, the written destination data of the board for service also might be changed to original setting.
Start the Adjust Manual in the Adjust Station and execute the “DESTINATON DATA WRITE”.

Note:  It is not necessary to execute the “DESTINATION DATA WRITE” for following destinations.

 

• AEP (A-2059-040-[])

 • 

E 

(A-2059-038-[])

 • 

CH 

(A-2059-039-[])

When you replace to a board for service, get the data from the former one.
Start the Adjust Manual in the Adjust Station and perform “USB SERIAL SAVE” to get the data.

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 new board for service, and therefore they must be entered after the board replacement.
After the board has been replaced with a board for service, start the Adjust Manual in the Adjust Station and execute the “PRODUCT ID & 
USB SERIAL No. INPUT” and enter these IDs.

Note: 

A newly entered Product ID is not always equal to the ID before board replacement. If the new ID differs from the previous ID, it may cause a difference 
from the ID registered by the customer.

When replacing the VC board, the CPU’s unique number (MAC address) must be reloaded. Perform the following procedure to reload the 
CPU’s unique number (MAC address).
1.  Download the latest-version Adjust manual.
2.  Install the downloaded Adjust manual.
3.  Execute “Wireless LAN Setting (MAC address)” on the ADJUST tab.

If “Wireless LAN Setting (MAC address)” is not executed and the backup data before replacement is restored, the MAC address in the Wi-Fi 
module does not match the MAC address in the flash memory, causing an error during Wi-Fi transfer.

A password required for Wi-Fi connection is recorded in every VC board. A label to present the password to the customer is stuck to every VC 
board for service. When the VC board is replaced, attach this label to the unit to be sent back.

Note:  The new SSID and password can be checked on the PC connected to the unit with a USB cable.

Note:  The [DATA LOAD AND WRITE] function in “ADJUSTMENT DATA BACKUP” on the DATA tab in the Adjust manual overwrites all data of the 

unit. Therefore, the MAC address updated during the above procedure is also overwritten. Perform the above operations “Update of MAC Address” 
after all work has been done.

After the replacement and repair, the MAC address is changed, and thus the re-setting for connection devices is required. 
Accordingly, download the Flyer of WLAN Reset (Flyer of WLAN Reset_9834752[][].pdf) and print out it, and attach it to the set when return-
ing the set to customer.

The handbook PDF is stored in the internal memory of the board for service.
The data of this handbook PDF differs depending on destinations.
