maintenance:
1. The system must be earthed properly. Please do not use two blade plugs
and ensure the AC power supply ranges from 100v to 240v and from 50Hz
to 60Hz.
2. Do not install the units in an environment where they will be exposed to
extreme hot or cold temperatures.
3. These units will generate heat during operation, please ensure that you allow
adequate ventilation to ensure reliable operation.
4. Please disconnect the units from mains power if they will be left unused for a
long time.
5. Please DO NOT try to open the casing of the equipment, DO NOT attempt to

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.

⚫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”.

version of HDMI output is HDCP 1.4 for broader
video solution.
⚫If the input video has no HDCP content, the HDMI
output has no HDCP too.
5. ARC Mode
The front panel of receiver provides a button to enable or disable ARC mode, as below
figure shows:
Press the button with paper clip or other sharp tool to enable the ARC mode, and then
the left LED illuminates blue. Press it again to exit the ARC mode and the LED is off.

ARC is supported
The TV audio is transmitted from the TV back to the
receiver via HDMI cable, and then it will 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 with an audio cable. The TV audio is
transmitted from the TV back to the receiver via the
audio cable, and then it will be output by the ARC
Audio Out port of transmitter.
Note that if the ARC mode is ON, the Audio
Breakout port of receiver has no audio output.
OFF
/
The TV audio can’t be back to the ARC Audio Out
port of transmitter. The Audio Breakout port of
receiver is connected to speaker or amplifier for
HDMI source audio de-embedding.
