5. DIP Switch Operation
5.1 EDID Management
The Extended Display Identification Data (EDID) is used by the source device to match
its video resolution with the connected display. By default, the source device obtains its
EDID from the first connected display. Meanwhile, since the displays with different
capabilities are connected to the splitter, the DIP switch on the front panel can be used
to set the EDID to a fixed value to ensure the compatibility in video resolution.
The switch represents “0” when in the lower (OFF) position, and it represents “1” while
putting the switch in the upper (ON) position.
Switch 1~3 are used for EDID setting. The DIP switch status and its corresponding
setting are shown at the back of the product.

7. Firmware Upgrade
Please follow the below steps to upgrade firmware by 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.
