1. Product Introduction
Thanks for choosing the HDMI 2.0 2x8 Splitter, which can distribute either one of
two HDMI inputs to eight outputs. The splitter supports HDMI video resolution up to
4K@60Hz 4:4:4, 1080P 3D and multichannel audio formats. Except passing EDID
information from the display, there are multiple built-in EDID settings can be
selected by the 4-pin DIP switch on the rear panel. The splitter can de-embed HDMI
digital audio to stereo analog L/R and Toslink SPDIF audio outputs to provide audio
sources for existing audio system.
CEC technology is adopted to turn on/off displays and adjust volume by the control
buttons on the front panel. Moreover, the splitter supports convenient firmware
upgrade through Micro-USB port.

5. 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 3-pin DIP switch on the
front panel and the 4-pin DIP switch on the rear panel can be used in combination
to set the EDID to a fixed value to ensure the compatibility in video resolution.
Switch Status
Description
L.RES
The splitter reads all EDID information from all connected displays,
and choose the one with lowest resolution passing to the source.
PRESET
In this mode, the 4-pin DIP switch on the rear panel can be used to
select predefined EDID and customize a specific EDID as need.
H.RES
The splitter reads all EDID information from all connected displays,
and choose the one with highest resolution passing to the source.
Predefined EDID setting
When the 3-pin DIP switch on the front panel is in PRESET mode, the 4-pin DIP
switch on the rear panel can be used to set the EDID to a built-in fixed value. Use
the following table to determine the settings for the 4-pin DIP switch for specific
video resolution and audio capabilities.

User defined EDID setting
Except directly invoking the built-in EDID, the specific EDID can be customized by
following the below operation process.
1) Rename the user defined EDID according the following format.
EC_xx_xxxx_xxx.bin
EC: Represents EDID.
xx: Represents EDID ID. It is “15”.
xxxx: Represents the video parameter.
xxx: Represents the audio format.
Example: EC_11_720P_LPCM.bin
2) Power on the splitter, and then connect to the PC with USB cable. 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 user defined EDID (such as EC_11_720P_LPCM.bin) to the “BOOTDISK”
U-disk.
5) Reopen the U-disk to check the filename “READY.TXT” whether automatically
becomes “SUCCESS.TXT”, if yes, the user defined EDID was imported into the
splitter and saved as its corresponding EDID ID successfully.
6) Remove the USB cable, and then reboot the splitter.
7) The new EDID now can be invoked via the 4-pin DIP switch directly. The EDID ID
and its corresponding switch status is shown in the below list.

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) Directly copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk.
5) Reopen the U-disk to check the filename “READY.TXT” whether automatically
becomes “SUCCESS.TXT”, if yes, the firmware was upgraded successfully,
otherwise, the firmware upgrade is fail, the name of upgrade file (.bin) should be
confirm again, and then follow the above steps to upgrade again.
