Click the update button to begin the firmware update process. After firmware update succeeds, click the finish button to close the prompt window.

After it connects successfully, there is a 3 confirmation sync-up prompt windows, the connected LEDs type (Monochrome or REG), Fail-Safe state (0 or 1) and EEPROM programming Mode (Chip select or External address). For each confirmation window, just click on the correct image mapping to the current EVM setup.
