UHD12-IPC230-K Overview and Use Cases

What Is the UHD12-IPC230-K?

The OREI UHD12-IPC230-K is an ipcolor 4K@60Hz HDMI 1x2 splitter extender over CAT6 / CAT6a / CAT7 cable. It distributes one HDMI source to two identical remote HDMI outputs and also includes an HDMI output on the Transmitter for a local display.

The kit includes one HDMI splitter extender Transmitter, two HDMI splitter extender Receivers, one DC 12V/3A power adapter, one RS-232 terminal block, one IR Blaster extension cable, two IR Receiver extension cables, mounting brackets, screws, and a user manual. The HDMI source connects to HDMI IN on the Transmitter, the local display connects to HDMI OUT on the Transmitter, and the two remote displays connect through the included Receivers using CAT6 / CAT6a / CAT7 cable.

The UHD12-IPC230-K supports HDMI 2.0 and HDCP 2.2. It supports video resolutions up to 4K@60Hz, 18Gbps, 4:4:4 HDR, zero-latency transmission, EDID management, two-way IR passback, RS-232 command control, S/PDIF audio output on the Receivers, and PoC so only the Transmitter requires power. It extends HDMI up to 70m / 230ft over CAT6 / CAT6a / CAT7 cable. 

The UHD12-IPC230-K is useful for multimedia classrooms, studios, conference rooms, retail displays, sports bars, restaurants, rail transit applications, digital signage, AV racks, and installations where one HDMI source needs to be shown on two remote displays.

IMPORTANT — UHD12-IPC230-K Is a 1x2 HDMI Splitter Extender

The UHD12-IPC230-K sends one HDMI source to two identical remote outputs.

This product duplicates one HDMI source. It does not create two independent video outputs or extended desktop screens.

IMPORTANT — Supports 4K@60Hz 4:4:4 HDR

The UHD12-IPC230-K supports high-resolution HDMI distribution up to 4K@60Hz.

To get 4K@60Hz, the HDMI source, displays, HDMI cables, CAT cables, and EDID settings must all support the required signal.

IMPORTANT — Maximum Distance Is 70m / 230ft

The UHD12-IPC230-K extends HDMI over CAT cable up to 70m / 230ft.

For best performance, use high-quality CAT6 / CAT6a / CAT7 cable with proper termination.

Poor cable quality, damaged connectors, weak terminations, couplers, or low-quality patch paths may reduce performance or cause no video.

IMPORTANT — Use Direct Interconnection CAT Cable

The manual states that the extender needs to follow the direct interconnection CAT cable method.

Use straight-through wiring, such as T568B to T568B.

The manual warns that the extender will automatically enter protection mode with no video output when using cross interconnection CAT cable.

IMPORTANT — Transmitter Has HDMI Local Output

The Transmitter includes HDMI OUT for a local display.

The local HDMI output and both Receiver outputs show the same HDMI source.

IMPORTANT — Receivers Have S/PDIF Audio Output

Each Receiver includes an S/PDIF output.

The Receiver audio switch allows the S/PDIF audio source to be selected.

Use the S/PDIF output when digital audio is needed near the remote display.

IMPORTANT — Two-Way IR Passback Is Supported

The UHD12-IPC230-K supports two-way IR passback.

This allows remote-control signals to pass between the Transmitter and Receiver locations.

Typical source-control setup:

• Connect the IR Receiver cable to the Receiver side. 
• Place the IR Receiver near the remote display. 
• Connect the IR Blaster cable to the Transmitter side. 
• Place the IR Blaster near the HDMI source device’s IR sensor. 

IMPORTANT — RS-232 Command Control Is Supported

The UHD12-IPC230-K supports RS-232 command control.

Default RS-232 settings:

Supported baud rate options include 9600, 19200, 38400, 57600, and 115200.

RS-232 can be used to:

• Turn network signal output ports on or off 
• Turn all output ports on or off 
• Restart the device 
• Restore factory settings 
• Change baud rate 

IMPORTANT — PoC Is Supported

The UHD12-IPC230-K supports PoC.

Only the Transmitter needs the power supply. The Receivers receive power through the CAT cable.

IMPORTANT — EDID Management Is Included

The product includes 16 built-in EDID settings controlled by the DIP switch.

The DIP switch uses:

EDID settings include:

The Auto mode outputs at a resolution compatible with all displays.

Use EDID when there is no video, wrong resolution, audio issue, HDR issue, or mixed display compatibility issue.

Ports and Panel Layout

Step-by-Step Setup

1. Connect the HDMI source device to HDMI IN on the Transmitter. 
   Examples include a Blu-ray player, cable box, streaming device, media player, laptop, desktop PC, DVR, NVR, or HDMI matrix output. 
2. Connect a local display to HDMI OUT on the Transmitter if needed. 
3. Connect RJ45 output port 1 on the Transmitter to Receiver 1 using CAT6 / CAT6a / CAT7 cable. 
4. Connect RJ45 output port 2 on the Transmitter to Receiver 2 using CAT6 / CAT6a / CAT7 cable. 
5. Connect each Receiver HDMI OUT to a TV, monitor, projector, or display. 
6. Connect the included DC 12V/3A power adapter to the Transmitter. 
7. If using digital audio output, connect the Receiver S/PDIF output to a soundbar, amplifier, speaker system, or audio receiver. 
8. Set the Receiver audio switch based on the required audio source. 
9. If using IR control, connect the IR Blaster to the Transmitter IR OUT. 
10. Connect IR Receiver cables to the Receiver IR IN ports. 
11. Set the EDID DIP switch based on the required video and audio format. 
12. If using RS-232 control, connect the RS-232 terminal block to the control system. 
13. Power on the HDMI source, displays, Transmitter, Receivers, and audio equipment. 
14. Check the power indicators and power / signal indicators. 
15. Test local HDMI output, Receiver HDMI outputs, S/PDIF audio output, IR control, and RS-232 control. 

CAT Cable Requirement — Critical

Use high-quality CAT6 / CAT6a / CAT7 cable.

Poor CAT cable may cause:

• No video 
• Flickering 
• Black screen 
• Protection mode 
• No signal on Receiver 
• 4K@60Hz not working 
• Audio dropouts 
• IR control issues 
• PoC power issues 

Use direct, properly terminated cable runs.

HDMI Cable Requirement — Critical

Use high-quality HDMI cables, especially for 4K@60Hz.

Poor HDMI cables may cause:

• No picture 
• Flickering 
• Black screen 
• HDR issues 
• HDMI source not detected 
• Local HDMI output not working 
• Receiver HDMI output not working 
• HDCP handshake issues 

For troubleshooting, test the HDMI source directly with a display before using the splitter extender.

Power Requirement — Critical

The UHD12-IPC230-K uses one DC 12V/3A power adapter at the Transmitter.

Power consumption:

If a Receiver does not power or does not show signal, check the Transmitter power, CAT cable, RJ45 output port, and Receiver connection.

Understanding the Transmitter

The Transmitter is installed near the HDMI source.

It has:

• HDMI IN 
• HDMI OUT local output 
• Two RJ45 output ports 
• EDID DIP switch 
• IR OUT 
• RS-232 
• Reset button 
• DC 12V power input 
• Power indicator 

The Transmitter splits one HDMI input into two network output signals and one local HDMI output.

Understanding the Receivers

Each Receiver is installed near a remote display.

Each Receiver has:

• RJ45 signal input 
• HDMI OUT 
• S/PDIF output 
• IR IN 
• Audio switch 
• Reset button 
• Power / Signal indicator 

The Receiver converts the signal back to HDMI and can output digital audio through S/PDIF.

Understanding Local HDMI Output

The Transmitter HDMI OUT is used for a nearby display.

This is useful for:

• AV racks 
• Source-side monitoring 
• Classrooms 
• Studios 
• Control desks 
• Digital signage testing 
• Restaurants and bars 

The local display and both remote displays show the same HDMI source.

Understanding S/PDIF Audio Output

The Receiver S/PDIF output lets audio be sent to a separate audio system near the remote display.

Use S/PDIF OUT for:

• Soundbars 
• Amplifiers 
• Audio receivers 
• Powered speaker systems 
• Digital audio systems 

The supported audio formats include LPCM, DTS-HD, DTS Audio, and Dolby Digital 5.1.

Understanding EDID

EDID tells the HDMI source what video and audio format to output.

Use EDID when:

• Displays show no signal 
• One display supports 4K but another supports only 1080p 
• Audio format does not work 
• HDR does not display correctly 
• The source outputs the wrong resolution 

For mixed displays, use Auto mode so the output uses a resolution compatible with all displays.

Understanding RS-232 Control

RS-232 control allows professional AV systems to control the Transmitter.

Common RS-232 uses include:

• Output port on / off control 
• Device restart 
• Factory reset 
• Baud rate change 
• Control processor integration 
• Installer troubleshooting 

The default baud rate is 9600.

Understanding Signal Indicators

Use these indicators first when troubleshooting.
