Here are the steps to install firmware upgrades using the Micro-USB port: 
1)

 

Connect the splitter to the PC with USB cable. 

2)

 

Power on the splitter, and then the PC will automatically detect a U-disk named 
of “BOOTDISK”. 

3)

 

Double-click to open the U-disk, a file named of “READY.TXT” will be showed. 

4)

 

Copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk directly. 

5)

 

If the filename “READY.TXT” automatically turns to “SUCCESS.TXT”, the firmware 
was upgraded successfully. If the firmware upgrade failed, please check the file 
(.bin) and then follow the above procedure to operate again. 

6)

 

Remove the USB cable after firmware upgrade.
