Introduction

4KEX70-W is an in wall 4K HDBT transmitter which includes an HDMI

input, a VGA input and an 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

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 oers ideal solutions for homes, oces, digital entertainment

centers, control centers, conference rooms, schools and corporate training

environments, which require signal switching between VGA and HDMI

sources and transmission over long distance.

EDID Management

EDID (Extended Display Identication 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:

Position 1 Position 2 Position 3 Functions

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 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]

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 qualied

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 denition

as below:

www.avaccess.com [email protected]

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 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 denition of RS232

during your installation.
