NOTE:

After clicking the ‘Program’ button, if the “Application Error” dialog box shown
on the right appears, or if you see the message “Connect Fail”, close the dialog box and click the ‘Program’ button again to continue the update process.

This dialog box may appear multiple times. If it does, try unplugging the connection cable between the controller and the PC, reconnecting it, and then clicking ‘Program’ button to update the program again.

ATTENTION:

“COM” port configuration is only required when running the update program software for the first time. Once the port has been configured, there is no need to reconfigure it again. If an “application error” dialog box or “connect fail” occurs during the program updating, you need to unplug the connection between the controller and the PC and try restarting the update. Re-configuring the UART port is not necessary.
