4. DIP Switch Operation
4.1 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.

6. 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.
