Introduction

4KEX70-W is an in wall 4K HDBT transmitter which includes an HDMI input, a VGA

input and a HDBT output, and is designed to work with an 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 the HDMI signals up to 131ft (40m) at 4K

and 230ft (70m) at 1080P over a CAT6a / 7 cable, or up to 115ft (35m) at 4K and

197ft (60m) at 1080P over a CAT5e / 6 cable.

This transmitter was developed to simplify the installation and create a clean

seamless look with your décor. It features one-way PoH function, allowing it to

receive power from an HDBT receiver with built-in PSE. It provides automatic and

manual button switch between the HDMI and VGA inputs. It also supports bi-

directional IR and RS-232 pass through.

4KEX70-W oers ideal solutions for homes, oces, digital entertainment centers,

Trouble Shooting

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 dierent 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.

Trouble Shooting

1. How to deal with video ash or cut o during the installation?

• 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/6/7, EIA/TIA 568B) and ensure the cable length is within the

maximum distance.

• 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, 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 definition as

below:

Typical Questions

www.avaccess.com

Trouble Shooting

• 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 RS 232 port in the extender?

The RS 232 port provides a channel to pass through protocol commands to

control third party devices such as your source or display. RS 232 uses the

three pins that are labeled transmitter, receiver and GND. Connect a host

computer or control system to the RS 232 connector. Please refer to the

following pin denition of RS 232 during your installation.
