Product Introduction

The WUH4ARC-8K is an auto switcher with four HDMI video inputs and one HDMI output. This switcher supports HDMI video resolution up to 8K@60Hz 4:2:4 HDR+ and High Definition audio. Except passing EDID information from the display, there are multiple built-in EDID settings to simplify an installation. The switcher will de-embed digital stereo audio to provide an analog audio source for an existing audio system. The switcher also supports enhanced audio return channel (eARC) for transmitting audio back to HDMI input port from the connected display. In auto-switch mode, it switches to an HDMI input as soon as a new source is connected. When the active input is removed, the switcher will select the first source on the lowest numbered input. The switcher may also be controlled via RS232, IR with the included remote, or from the source button on the front of the switcher.

User Defined EDID Setting
Except directly invoking the embedded EDID, the specific EDID can be customized. There are five EDID can be customized following the below operations.

1. Rename the user defined EDID according the following format.
   EC_xx_xxxx_xxx.bin

2. EC: Represents EDID.

3. xx: Represents EDID ID. It is 11~15.

4. xxxx: Represents the video parameter.

5. xxx: Represents the audio format.
   Example: EC_11_720P_LPCM.bin

6. Power on the switcher, and then connect the switcher to the PC with USB cable. The PC will automatically detect a U-disk named of “BOOTDISK”.

7. Double-click the U-disk, a file named of “READY.TXT” would be showed.

8. Copy the user defined EDID (such as EC_11_720P_LPCM.bin) to the
   “BOOTDISK” U-disk.

9. 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 switcher and saved as its corresponding EDID ID successfully.

10. Repeat the above third to fifth step to copy other user defined EDIDs to the
    “BOOTDISK” U-disk.

11. Remove the USB cable, connect the adaptor to power on the switcher.

12. The new EDID also can be invoked via the 4-pin DIP switch directly. The EDID ID and its corresponding switch status are shown in the below list.
    ID| Switch Status
    ---|---
    11| 1011
    12| 1100
    13| 1101
    14| 1110

1. Prepare the latest upgrade file (.bin) and rename it as “USERAPP.bin”
2. Connect the switcher to the PC with USB cable, and then power on the switcher. The PC will automatically detect a U-disk named of “BOOTDISK”.
3. Double-click the U-disk, a file named of “READY.TXT” would 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 updated successfully, otherwise, the firmware updating is fail, the name of upgrade file (.bin) should be confirm again, and then follow the above steps to update again.
6. Remove the USB cable after firmware upgrade.
