UHD-IPC230-CS Overview and Use Cases

What Is the UHD-IPC230-CS?

The OREI UHD-IPC230-CS is an ipcolor 4K@60Hz HDMI extender over CAT6 / CAT6a / CAT7 cable with HDMI loop out, cascading support, downscaling, bi-directional IR, and Receiver-side digital audio extraction. It extends one HDMI source to one or multiple HDMI displays using a Transmitter and Receiver system.

The kit includes one Transmitter, one Receiver, two DC 5V/2A power adapters, one IR Receiver extension cable, one IR Blaster extension cable, mounting brackets, screws, and a user manual. The HDMI source connects to HDMI INPUT on the Transmitter, a local display can connect to HDMI OUTPUT on the Transmitter, and the Receiver connects to a remote HDMI display through HDMI OUTPUT.

The UHD-IPC230-CS supports HDMI 2.0 and HDCP 2.2. It supports video resolutions up to 4K@60Hz, 18Gbps, HDR, YUV 4:4:4, zero latency, HDMI loop out on the Transmitter, cascading up to 10 Receivers, automatic downscaling to adapt to display resolution, bi-directional IR passback, and digital audio extraction from the Receiver through the S/PDIF port. It extends 4K@60Hz HDMI up to 70m / 230ft through CAT6 / CAT6a / CAT7 cable, or up to 50m / 165ft when cascading Receivers. 

The UHD-IPC230-CS is useful for classrooms, conference rooms, sports bars, restaurants, retail displays, digital signage, AV racks, control rooms, security monitoring, and commercial installations where one HDMI source needs to be extended to one display or cascaded to multiple displays.

IMPORTANT — UHD-IPC230-CS Supports Cascading

The UHD-IPC230-CS supports one-to-one and one-to-many cascading.

All Receivers show the same HDMI source. This product duplicates and extends the source signal; it does not create independent extended desktop screens.

IMPORTANT — Supports 4K@60Hz

The UHD-IPC230-CS supports HDMI video up to 4K@60Hz.

To get 4K@60Hz, the HDMI source, display, HDMI cables, CAT cable, and source output settings must support the required signal.

IMPORTANT — Maximum Distance Depends on Setup

The UHD-IPC230-CS supports different transmission distances depending on whether it is used one-to-one or in cascade mode.

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

Poor cable quality, weak terminations, couplers, damaged connectors, or long patching paths may reduce performance.

IMPORTANT — Use Direct CAT Cable Connections

Use direct CAT6 / CAT6a / CAT7 cable between the Transmitter and Receiver, or between cascaded Receivers.

Do not connect this product through:

• Network switch 
• Router 
• Internet network 
• LAN switch 
• Standard Ethernet network 

The manual shows a direct one-to-one connection and one-to-many cascade layout. It is not shown as an AV-over-IP network switch system.

IMPORTANT — Direct Interconnection CAT Cable Is Required

The manual cautions that the extender needs direct interconnection CAT cable.

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

Do not use cross interconnection wiring.

If there is no video, check the CAT cable termination first.

IMPORTANT — HDMI Loop Out Is on the Transmitter

The Transmitter includes HDMI OUTPUT.

This HDMI output can be used for a local display near the HDMI source.

This is useful for AV racks, source rooms, control stations, classrooms, sports bars, and installations where the source-side location also needs a display.

IMPORTANT — Auto Downscaling Is Supported

The UHD-IPC230-CS supports auto downscaling.

This allows the Receiver to adapt to the connected display resolution.

Use downscaling when:

• A 4K source is connected 
• One display supports 4K 
• Another display supports only 1080p 
• A remote display does not show video from a higher-resolution source 

This helps mixed-display installations where not every screen supports the same resolution.

IMPORTANT — Receiver Has S/PDIF Audio Output

The Receiver can extract digital audio through the S/PDIF port.

Supported audio formats include:

• LPCM 
• DTS-HD 
• DTS Audio 
• Dolby TrueHD 
• 7.1CH audio 
• Dolby Digital 5.1CH 

Use the S/PDIF output to connect an audio receiver, soundbar, amplifier, or digital audio system.

IMPORTANT — Receiver Audio Switch Is Included

The Receiver includes an audio switch.

Use this switch depending on whether the audio should come from the HDMI signal or the optical / ARC-related audio path.

IMPORTANT — Bi-Directional IR Is Supported

The UHD-IPC230-CS supports bi-directional IR passback from 20kHz to 60kHz.

This allows IR control in both directions:

Typical source-control setup:

• Connect the IR Receiver cable to IR IN on the Receiver. 
• Place the IR Receiver near the remote display. 
• Connect the IR Blaster cable to IR OUT on the Transmitter. 
• Place the IR Blaster near the HDMI source device’s IR window. 

Typical display-control setup:

• Connect the IR Receiver cable to IR IN on the Transmitter. 
• Connect the IR Blaster cable to IR OUT on the Receiver. 
• Place the IR Blaster near the display’s IR window. 

IMPORTANT — Both Units Need Power

The UHD-IPC230-CS includes two DC 5V/2A power adapters.

Power consumption is listed as:

Both units should be powered for normal operation.

Power Requirement — Critical

Both units use DC 5V/2A power.

If the power / signal indicator does not light, check the power adapter, outlet, DC 5V input, and power connection.

Understanding the Transmitter

The Transmitter is installed near the HDMI source.

It has:

• HDMI INPUT 
• HDMI OUTPUT loop out 
• CAT OUT 
• IR IN 
• IR OUT 
• DC 5V input 
• Reset button 
• Power / signal indicator 

The Transmitter receives the HDMI source signal, provides a local HDMI loop output, and sends the signal over CAT cable to the Receiver.

Understanding the Receiver

The Receiver is installed near the remote display.

It has:

• CAT IN 
• CAT OUT for cascading 
• HDMI OUTPUT 
• S/PDIF OUT 
• IR IN 
• IR OUT 
• Audio switch

• Reset button 
• Power / signal indicator 

The Receiver converts the CAT signal back to HDMI, provides digital audio output, and can cascade the signal to another Receiver.

Understanding Cascading

Cascading allows one HDMI source to feed multiple displays without using a separate HDMI splitter.

Basic cascade layout:

The manual states support for up to 10 Receivers in cascade mode.

Understanding HDMI Loop Output

The Transmitter HDMI OUTPUT is used for local display connection.

This allows the HDMI source to be displayed near the source location while the same signal is extended to remote Receivers.

Use HDMI loop out for:

• AV racks 
• Control desks 
• Source-side monitoring 
• Classrooms 
• Restaurants 
• Bars 
• Digital signage installations 
• Testing during installation 

Understanding Downscaling
