Product Introduction
Thanks for choosing the ARC-HDEX40ARC HDMI 2.0 Extender, which consists of a
transmitter and a receiver. It can extend 4K video to distance up to 131 feet (40
meters) and 1080P video to distances up to 230 feet (70 meters) over a single CATx
cable. It supports audio de-embedded and ARC. It also supports bidirectional IR and
RS232 pass-through to control source or display device remotely. PoC feature allows
the transmitter and the receiver can be powered from each other and only one power
adapter is needed in system. Besides passing EDID information from the display, there
are multiple built-in EDID settings can be selected by the 4-pin DIP switch on the front
panel of transmitter. Moreover, the extender supports convenient firmware upgrade
through Micro-USB port.

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.
Switch 1~3 are used for EDID setting. The DIP switch status and its corresponding
setting are shown at the back of the product.

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_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”.

If the input video has HDCP content, the HDCP
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.
ARC Mode
The front panel of receiver provides a buttons 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.

Display (e.g.TV)
Audio Transmission Path
ON
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.
System Connection
The following diagram illustrates the typical input and output connections of the
extender:
1) The ARC mode of receiver is ON, and the display device (e.g. HDTV) supports
ARC. 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.
Note: The STP cable is recommended to be used to ensure optimal machine
performance in ARC mode.
