4. DIP Switch Operation
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 extender, the DIP switch on the front panel
of transmitter 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.
Switches 1~3 are used for EDID setting. The DIP switch status and its corresponding
setting are shown on the back of the product.

▪2CH: Supports LPCM 2CH.
▪Multi-CH: Supports LPCM 8CH, Dolby TrueHD, DTS-HD , Dolby Digital5.1, DTS

⚫User-defined EDID Setting
Except directly invoking the built-in EDID, the specific EDID can be customised by
following the below operation process.
1) Rename the user-defined EDID according the following format.
EC_xx_xxxxx_xxxx_xxx.bin
⚫EC: Fixed value
⚫xx: EDID ID. It is “15”.
⚫xxxxx: Video resolution.
⚫xxxx: Refresh rate.
⚫xxx: Audio format.
Example: EC_15_3840x2160_60Hz_ Dolby.bin
2) Connect the FW port of transmitter to the PC with USB cable, and then power on
the transmitter, the PC will automatically detect a virtual disk named of
“BOOTDISK”.
3) Double-click to open the disk, a file named of “READY.TXT” will be showed.
4) Copy the user-defined EDID (such as EC_15_3840x2160_60Hz_Dolby.bin) to the
“BOOTDISK” disk.
5) Reopen the disk to check the filename “READY.TXT” whether automatically
becomes “SUCCESS.TXT”, if yes, the user-defined EDID was imported into the
transmitter and saved as its corresponding EDID ID successfully.
6) Remove the USB cable, and then reboot the transmitter.
7) Now the new EDID can be invoked by setting the DIP switch status to “111”.
