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 c onnect 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

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
    15| 1111

ARC Mode

Audio Return Channel (ARC) allows audio from a display to pass “upstream” through an HDMI cable to an audio processing device, such as an AV amplifier . When ARC mode is active on the switcher, the ARC stream will pass to the active HDMI sourcedevice if it can process the signal.
Only the fourth HDMI input port features ARC, when the display and AV amplifier support ARC, the audio connection diagram is shown below:

Firmware Upgrade
Please follow the steps as below to upgrade firmware by the Micro USB port on the rear panel:

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 a utomatically 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 autom atically 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 fi rmware upgrade.
