HDBT receiver such as the 4KEX70-RX-PSE. It supports resolutions up to
4K@60Hz 4:2:0 8bit and HDCP for the HDMI signal. It can reliably extend
HDMI signal up to 131ft (40m) at 4K and 230ft (70m) at 1080P over a Cat
6a/7 cable, or up to 115ft (35m) at 4K and 197ft (60m) at 1080P over a Cat
5e/6 cable.
4KEX70-W transmitter was developed to simplify the installation and
create a clean seamless look with your décor. Through one-way PoH
function, it can receive power from an HDBT receiver with built-in PSE.
4KEX70-W allows automatic and manual button switch between HDMI
and VGA inputs. It also supports bi-directional IR and RS232 pass-through.
4KEX70-W oers ideal solutions for homes, oces, digital entertainment
centers, control centers, conference rooms, schools and corporate training
environments, which require signal switching between VGA and HDMI

EDID (Extended Display Identication Data) is a data structure generated
by a digital display to communicate its capabilities, such as its native
resolution, to the attached source device.
For VGA input, fixed EDID can be set using the EDID DIP switch on the
front panel.
The default setting is "010", please set EDID according to the following
table:

Steps of Regular Troubleshooting Routine
1. Power: Please make sure all devices are powered on (sources,
transmitter, receiver and display).
2. Indicator: Please make sure LED indicators of the transmitter and
receiver are normal according to user manual.
3. Devices: Please make sure picture can be shown normally when
connecting the source to the display directly.
4. Cable: Plug in and out HDMI/Cat X cable or try another HDMI/Cat X
cable.
• Please make sure the specific cable length is within the
transmission range listed in below table based on different
resolutions.

• Cat 5e/6/6a/7 cable is recommended. Do not use Cat 5 cable.
Please make sure the two connectors of one Cat X cable are the
same standard (EIA/TIA 568B).
5. Compatibility: Please test other source and display devices to
determine if it is a compatibility issue.

Typical Questions
1. How to deal with video ash or cut o during the installation?
www.avaccess.com [email protected]
14
Trouble Shooting
• Link indicator should be solid on. If it is blinking or o, it is likely
a problem with your Ethernet cable. Please change to a qualied
cable (Cat 5e/6/7, EIA/TIA 568B) and ensure the cable length is
within the maximum transmission distance.
• HDCP indicator should be solid on or blinking. If it is o, it means
no signal pass through. Please check if the HDMI cables are
well connected to the source and TV, and the CATX cable that
connects transmitter to receiver is normal. Try a better HDMI
cable or CATX cable.
2. How to deal with a weak or not working IR signal?
• Make sure the IR cables are correctly installed according to the
Installation Instruction 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 to adjust 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 0° 30°(Horizontal) 15°(Vertical)
Distance 26ft (Max) 15ft (Max) 10ft (Max)
3. How can I make the IR work with third party control devices?
• Please make sure the third party device follows our pin denition

• You can purchase an AV Access universal IR cable that will
be compliant with any third party device (Amazon ASIN:
"B01MYX46IC").
4. 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 denition of RS232
during your installation.
