• ③ EDID: 4-pin DIP switch for EDID setting. Please refer to the 5.EDID Management for more details.
• ④ DC 12V: DC barrel port to connect an AC power adapter.

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.

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.
When in the lower position, the switch represents “0”, while putting the switch in the upper position, it represents “1”.

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_15_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.

Video Resolution Down-scaling

The product supports video resolution down-scaling, the 4K input can be automatically degraded to 1080P output for compatibility with 1080P display, shown in the below chart.

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 updating is fail, the name of upgrade file (.bin) should be confirm again, and then follow the above steps to upgrade again.
6. Remove the USB cable after firmware upgrade.
