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

www.avaccess.com

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

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.
