RS232 Wiring
RS232 Connection Guidelines
The following wiring diagram shows the pinouts for the extender set.
While not shown, connect the TX (transmit) to RX (receive) pins at the
control system or PC side of the cable.
Most control systems and computers are DTE where pin 2 is RX,
this can vary from device to device. Refer to the documentation for
the connected device for pin functionally to ensure that the correct
connections can be made.
Pin 1: TX (Transmit)
Pin 2: RX (Receive)
Pin 3: Ground (GND)
Wire colors shown follow EIA-561 standard
EDID Presets

EDID Presets
Distribution of HD signals through device requires mutual communication or
'handshake' between source and display. If there is any disparity between the
two, successful transmission becomes problematic.
4KEX70-ARC comes equipped with EDID management on the Transmitter to
encourage communication between INPUT and OUTPUT devices. If
compatibility issues arise during installation, check the settings on your
connected devices and adjust the DIP settings as required.
Note: The default mode is 1080p stereo.

Trouble Shooting
Five Steps of Regular Troubleshooting Routine
1. Power: Make sure all devices are powered on. (source, extender,
display devices)
2. Indicator: Make sure LED indicators of transmitter and receiver are
normal according to user manual.
3. Devices: Make sure picture can be shown normally when connecting
source to display devices directly.
4. Cable: Plug in and out HDMI/CatX cable or try another HDMI/CatX
cable.
Cat 5e/6/6a/7 cable is recommended, do not use Cat 5 cable.
Make sure CatX cable is less than 230ft for 1080p, 130ft for 4K
resolution.
Make sure the two connectors of one CatX cable are same standard
(EIA/TIA 568B).
5. Compatibility: Please test other source and display devices to
determine whether it is a compatibility issue.
Typical questions
1. How to deal with video flash or cut off during the installation?
Power indicator should be solid on and status indicator should be
blinking. If not, please check if the power adapter is well
connected.
Link indicator should be solid on, if it is blinking or off, it is likely a
problem with your Ethernet cable, please change to a qualified
cable (Cat5e/6/6a/7, EIA/TIA 568B) and make sure the cable

length is within the maximum distance (230ft for 1080p, 130ft for
4K).
HDCP indicator should be solid on or blinking, if it is off, it means
no signal pass through, please check if the HDMI cables are well
connected to the source and TV. Try to change to a better HDMI
cable. Also, make sure that your source and TV are under 4k@60
(420 8bit).
2. How to deal with a weak or not working IR signal?
Make sure the IR cables are correctly installed according to the
diagram above.
Check if the IR emitter head is secured over the center of the device
IR receiver window. The best position may vary depending on the
device, please refer to the device user manual. If the signal is weak,
please try adjusting the position.
Pay attention to the control angle and distance as below: The
control signal will be better when your controller is pointed at the IR
receiver head directly.
Enabled Angle

15°(Vertical)
Distance

3. Why the HDCP light is flashing?
HDCP light solid on: Audio and Video signal is HDCP protected.
HDCP light flashing: Audio and Video signal are not HDCP protected.
This is normal and will not affect operation.

4. How can I make the IR work with third party control devices?
Please make sure the third party device follows our pin definition as
below:
You can purchase a AV Access universal IR cable that will be
compliant with any third party device.(Amazon ASIN:
"B01MYX46IC")
5. How to use the RS232 port in the extender?
The RS232 port provides a channel to pass through protocol commands
to control third party devices such as your source or display. RS232 uses
the three pins that are labeled transmitter, receiver and GND. Connect a
host computer or control system to the RS232 connector. Please refer to
the following pin definition of RS232 during your installation.
