Overview
Overview
The 4KEX70-VH HDMI extender is a slim transmitter receiver pair which is
designed to extend HDMI 1080P@60Hz signals up to 70 meters and 4K@60Hz
signals up to 40m via a single Cat 6a/7 cable. The transmitter can supply the
power for the receiver. You can control the source from the display's location or
control the display from source's location via IR pass-through function.
VGA and HDMI inputs are automatically selected and switched when the unit
detects a signal, with a smart detection feature prioritizing HDMI over VGA if two
devices are transmitting at the same time.
Including serial control support compatible with leading control systems, it offers
an excellent solution to any commercial or residential environment where
switching between VGA with audio and HDMI over distance is required.
Via Cat 6a/7 cables, 4Kx2K@60Hz (4:2:0) output up to 40m, 1080P@60Hz up to
70m
Via Cat 5e cable, 4Kx2K@60Hz (4:2:0) output up to 35m, 1080P@60Hz up to
60m
Transfers bi-directional infrared control signal together with the HDMI signal
Transmitter supplies the power for receiver
Auto-switch between VGA and HDMI inputs, HDMI IN has higher priority over
VGA IN if both are connected
HDMI 1.4 with 4K and HDCP 2.2 compliant
Supports Bi-directional RS232 pass through

According to the bi-direction RS232 pass through function, you can use two
RS232 devices for serial communication by connecting to the transmitter and
receiver via RS232 cables in order to control the source device or the display.
1. Ensure the source device and the display device are connected
separately to transmitter and the receiver as shown.
2. Connect the RS232 devices to RS232 port of transmitter and receiver
using the RS232 cables.
3. Connect HDBT OUT of transmitter and HDBT IN of receiver using a
CatX cable.

Five Steps of Regular Troubleshooting Routine
1. Power: Please make sure all devices (source, extender, display) are powered
on.
2. Indicator: Please make sure LED indicators of transmitter and receiver are
normal according to user manual.
3. Devices: Please make sure picture can be shown normally when connecting
source to display devices directly.
4. Compatibility: Please test other source and display devices to determine
whether it is a compatibility issue.
5. 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.
Please make sure CatX cable is less than 130ft for 1080p resolution.
Please make sure the two connectors of one CatX cable are same standard
(EIA/TIA 568B).
Typical questions
1. How to deal with video flash or cut off during installation?
Power indicator should be solid on. If not, please check if the power
adapter is well connected.
Status indicator should be blinking and Link indicator should be solid
on. If it is not, please check the HDMI cables are qualified and well
connected. Change to a qualified CatX cable (Cat5e/6/7, 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
www.avaccess.com 11

Trouble Shooting
sure that your source and TV are under 4k@60 (420 8bit).
Check the cable, refer to Step 5 above.
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 0° 30°(Horizontal) 15°(Vertical)
Distance 8m(Max) 4.5m(Max) 3m(Max)
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.
