1) Prepare the latest upgrade file (.bin) and rename it as “FW_MV.bin” on PC.
2) Power off the switcher and connect the FIRMWARE port of switcher to the PC with a type-A USB cable.
3) Power on the switcher, the PC will automatically detect a U-disk named “BOOTDISK”.
4) Directly copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk.
5) Reopen the U-disk to check whether there is a filename “SUCCESS.TXT”, if yes, the firmware was updated successfully, if not, the firmware updating has failed, the name of upgrade file (.bin) should be confirmed again, and then follow the above steps again to update.
6) Remove the type-A USB cable after firmware upgrade.
7) After firmware upgrade, the switcher should be restored to factory default by sending a command.
