UHD-IPC230-KVM Overview and Use Cases

What Is the UHD-IPC230-KVM?

The OREI UHD-IPC230-KVM is a 4K@60Hz HDMI extender with KVM function. It sends HDMI video, HDMI audio, USB keyboard/mouse control, and digital audio output over a single CAT 6 / CAT 6A / CAT 7 cable.

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

The UHD-IPC230-KVM supports HDMI 2.0 and HDCP 2.2. It supports video resolutions up to 4K@60Hz, HDR, YUV 4:4:4, HDMI loop out on the Transmitter, KVM function, SPDIF digital audio output, and transmission distance up to 70m over CAT 6 / CAT 6A / CAT 7 cable.

The UHD-IPC230-KVM is useful for conference rooms, classrooms, monitoring systems, home entertainment setups, offices, digital signage, and installations where a computer or HDMI source needs to be extended with keyboard and mouse control.

IMPORTANT — UHD-IPC230-KVM Supports 4K@60Hz

The UHD-IPC230-KVM supports video resolutions up to 4K@60Hz.

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

If the source is set to 4K and there is no output, make sure the HDMI cables support 4K and the source output is set to a supported resolution.

IMPORTANT — Transmission Distance Is up to 70m

The UHD-IPC230-KVM can transmit 4K@60Hz HDMI signal up to 70m over CAT 6 / CAT 6A / CAT 7 cable.

The manual recommends using a CAT cable length between 2m and 70m.

If the cable is too short, there may be no display output because the signal may be too strong.

If the cable is too long, the output may have poor quality.

IMPORTANT — Use CAT 6 / CAT 6A / CAT 7 Cable

For best performance, use a high-quality CAT 6 / CAT 6A / CAT 7 cable.

Poor-quality cable may cause:

1. No video
2. Flickering
3. Black screen
4. Poor color
5. No sound
6. KVM not working
7. Signal dropouts
8. Poor output quality

IMPORTANT — Use IEEE-568B Wiring

The manual recommends following the IEEE-568B wiring standard.

The listed wiring order is:

Use a network cable with less loss and less crosstalk for best results.

IMPORTANT — Use a Direct CAT Cable Connection

The UHD-IPC230-KVM should be connected directly from the Transmitter RJ45 output to the Receiver RJ45 input.

Do not connect it 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 extension cable between the Transmitter and Receiver.

IMPORTANT — Both Transmitter and Receiver Need Power

The package includes two DC 5V/2A power adapters.

This means both the Transmitter and Receiver need their own power connection.

Use only DC 5V–12V power supply as listed in the manual, and make sure the power adapter specification matches the product requirement.

IMPORTANT — KVM Function Is Supported

The UHD-IPC230-KVM supports KVM function.

This allows a keyboard and mouse connected at the Receiver side to control the computer connected at the Transmitter side.

The Transmitter connects to the computer using the USB cable.

The Receiver has USB ports for keyboard and mouse.

IMPORTANT — HDMI Loop Out Is on the Transmitter

The Transmitter includes an HDMI OUT port.

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

For example, a PC can connect to the Transmitter HDMI IN, a local monitor can connect to the Transmitter HDMI OUT, and the remote display can connect to the Receiver HDMI OUT.

IMPORTANT — Receiver Has SPDIF Digital Audio Output

The Receiver includes an SPDIF OUT port.

This port can output digital audio to a compatible speaker, amplifier, soundbar, or audio system.

The manual lists supported audio formats including:

1. LPCM
2. DTS-HD
3. DTS-Audio
4. Dolby Digital 5.1CH

IMPORTANT — No IR or RS-232 Control Listed

The UHD-IPC230-KVM manual does not list IR IN, IR OUT, or RS-232 ports.

This model is focused on HDMI extension, KVM control, HDMI loop out, and SPDIF audio output.

If IR remote control or RS-232 control is required, use a different extender model that includes those ports.
