DIP Switch Operation
EDID Management
The Extended Display Identification Data (EDID) is used by the source device to
match its video resolution ith the connected display. By default, the source device
obtains its EDID from the first connected display. Mean hile, since the displays ith
different capabilities are connected to the extender, the DIP s itch 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 s itch represents “0” hen in the lo er (OFF) position, and it represents “1” hile
putting the s itch in the upper (ON) position.
S itch 1~3 are used for EDID setting. The DIP s itch status and its corresponding
setting are sho n at the back of the product.

User-defined EDID Setting
Except directly invoking the built-in EDID, the specific EDID can be customized by
follo ing the belo operation process.
1) Rename the user-defined EDID according the follo ing 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 ith USB cable, and then po er on
the transmitter, the PC ill automatically detect a virtual disk named of
“BOOTDISK”.
3) Double-click to open the disk, a file named of “READY.TXT” ill be sho ed.
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” hether automatically
becomes “SUCCESS.TXT”, if yes, the user-defined EDID as imported into the
transmitter and saved as its corresponding EDID ID successfully.
6) Remove the USB cable, and then reboot the transmitter.
7) No the ne EDID can be invoked by setting the DIP s itch status to “111”.

ill be output by the ARC Audio Out port of
transmitter.
ARC is not supported
Connect the TV to the ARC Audio In port of
receiver ith an audio cable. The TV audio is
transmitted from the TV back to the receiver
via the audio cable, and then it ill be output
by the ARC Audio Out port of transmitter.
