UHD-IPC165-K Overview and Use Cases

What Is the UHD-IPC165-K?

The OREI UHD-IPC165-K is a 4K@60Hz HDMI extender kit that sends HDMI video and audio up to 70m / 230ft over a single CAT 6 / CAT 6a cable.

The kit includes a Transmitter and Receiver. The HDMI source connects to the Transmitter, the display connects to the Receiver, and a CAT cable connects the Transmitter to the Receiver.

The UHD-IPC165-K supports HDMI 2.0 and HDCP 2.2, with a video bandwidth of 18Gbps. It supports video resolutions up to 4K@60Hz, EDID pass-through, bi-directional PoC, HDMI loop out on the Transmitter, zero-latency uncompressed AV transmission, and HDMI audio formats including LPCM 2.0, Dolby 5.1, DD+ 7.1, and DTS 5.1.

The UHD-IPC165-K is useful for classrooms, conference rooms, digital signage, demonstration setups, video conferencing, multimedia teaching, offices, retail displays, and AV installations where a 4K HDMI source needs to be extended to a display using CAT cable.

IMPORTANT — UHD-IPC165-K Supports 4K@60Hz

The UHD-IPC165-K supports video resolutions up to 4K@60Hz.

This makes it suitable for HDMI 2.0 setups that need to extend a 4K signal farther than a standard HDMI cable can normally reach.

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

IMPORTANT — Extends up to 70m / 230ft Over CAT 6 / CAT 6a

The UHD-IPC165-K extends HDMI up to 70m / 230ft over a single CAT 6 / CAT 6a cable.

For best performance, use high-quality shielded CAT 6 cable.

Poor-quality CAT cable may cause:

1. No video
2. Flickering
3. Black screen
4. Signal dropouts
5. 4K@60Hz not working
6. Audio dropouts
7. Receiver not powering correctly

IMPORTANT — Use a Direct CAT Cable Connection

The UHD-IPC165-K requires a direct connection between the Transmitter and Receiver.

Do not connect the extender through:

1. Network switch
2. Router
3. Internet network
4. LAN switch
5. Home network distribution system 
    
   This product is not an AV-over-IP extender. The CAT cable is used as a direct HDMI signal extension cable between the Transmitter and Receiver.

IMPORTANT — Bi-Directional PoC Is Supported

The UHD-IPC165-K supports bi-directional PoC, meaning Power over Cable.

Only one power adapter is required.

The power adapter can be connected to either:

1. Transmitter side
2. Receiver side 
    
   The other unit receives power through the CAT cable. 
    
   If one side does not power on, check the CAT cable connection and confirm the included 12V/1A power adapter is connected to one end.

IMPORTANT — HDMI Loop Out Is on the Transmitter

The Transmitter includes an HDMI OUT port.

This HDMI OUT port is used as a local loop output near the source.

For example, a Blu-ray player can connect to the Transmitter HDMI IN, a nearby monitor or TV can connect to the Transmitter HDMI OUT, and the remote display can connect to the Receiver HDMI OUT.

IMPORTANT — No IR Control Ports

The UHD-IPC165-K manual does not list IR IN, IR OUT, IR receiver, or IR blaster ports.

This model is for HDMI video and audio extension only.

If IR remote control extension is required, use an HDMI extender model that includes IR control.

IMPORTANT — No Separate Audio Extraction Output

The UHD-IPC165-K does not include a separate Optical, Coaxial, RCA, or 3.5mm audio output.

Audio passes through HDMI to the connected display or HDMI audio device.

If separate audio extraction is needed, use an extender model with built-in audio output.

IMPORTANT — EDID Pass-Through Is Supported

The UHD-IPC165-K supports EDID pass-through.

EDID pass-through helps the source device detect the connected display’s supported resolution and audio format.

If there is no video, wrong resolution, or audio compatibility issue, check the display capability, HDMI cable, CAT cable, and source output settings.

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, DVD player, streaming device, cable box, laptop, desktop PC, or media player.
2. Connect a local display to HDMI OUT on the Transmitter if needed.
3. Connect the remote display to HDMI OUT on the Receiver.
4. Connect CAT OUT on the Transmitter to CAT IN on the Receiver using a CAT 6 / CAT 6a cable.
5. Connect the included 12V/1A power adapter to either the Transmitter or the Receiver.
6. Power on the HDMI source device and displays.
7. Confirm that the Power LEDs are on.
8. Test video and audio.
9. If there is no signal, check the CAT cable, HDMI cables, source resolution, and direct connection requirement.

CAT Cable Requirement — Critical

For best performance, use a high-quality shielded CAT 6 / CAT 6a cable.

The manual lists:

Poor-quality, damaged, or incorrectly terminated CAT cable may cause:

1. No video
2. Flickering
3. Black screen
4. Receiver not powering on
5. 4K@60Hz not working
6. Audio dropouts
7. Signal instability 
    
   Do not connect the CAT cable through a network switch or router.

HDMI Cable Requirement — Critical

Use high-quality HDMI cables for the source, local display, and remote display.

Poor HDMI cables may cause:

1. No picture
2. Flickering
3. Audio dropouts
4. 4K@60Hz not working
5. HDCP handshake issues
6. No signal on the local display
7. No signal on the remote display 
    
   For troubleshooting, test the HDMI source directly with the display before using the extender.

Understanding the Transmitter

The Transmitter is installed near the HDMI source device.

It has:

1. HDMI IN for the source
2. HDMI OUT for local loop output
3. CAT OUT to connect to the Receiver
4. Power LED
5. DC 12V power input 
    
   The Transmitter can be powered directly using the included power adapter, or it can receive power through the CAT cable if the Receiver side is powered.

Understanding the Receiver

The Receiver is installed near the remote display.

It has:

1. CAT IN from the Transmitter
2. HDMI OUT to the remote display
3. Power LED
4. DC 12V power input 
    
   The Receiver can be powered directly using the included power adapter, or it can receive power through the CAT cable if the Transmitter side is powered.

Understanding HDMI Loop Out

The HDMI OUT port on the Transmitter is a loop output.

This allows a local display to be connected near the HDMI source.

Example setup:

This is useful when the source needs to be viewed both near the equipment rack and at a remote display location.

Understanding Bi-Directional PoC

PoC stands for Power over Cable.

The UHD-IPC165-K supports bi-directional PoC, which means the included power adapter can be connected to either side.

Only one power adapter is included and only one power adapter is needed.

Understanding EDID Pass-Through

EDID tells the HDMI source what video and audio formats the connected display supports.

The UHD-IPC165-K supports EDID pass-through, allowing the source to communicate with the connected display through the extender.

This helps with:

1. Resolution detection
2. Audio format detection
3. HDMI handshake
4. Display compatibility 
    
   If there is no signal, try power cycling the source device after the display and extender are connected.
