4K HDMI & USB KVM Extender

This extender sends 4K60 HDMI video and USB 1.1 keyboard or mouse signals over a single Cat 6 cable up to 70 metres. Bi-directional power over cable lets one 12 V adapter run both the transmitter and receiver. The ultra-slim chassis includes mounting brackets for tight spaces behind displays or inside lecterns. It passes multichannel audio including Dolby Atmos and DTS:X.

Suits remote-control workstations.

Installers who need a computer in a secure rack and a display with keyboard and mouse at a podium, classroom desk or retail counter will find the 230 ft reach and single-cable simplicity ideal. Users who require USB 2.0 or 3.0 throughput for storage devices, webcams or audio interfaces should look at a different extender because this unit only carries USB 1.1 HID traffic.

70 metre Cat 6 reach decides the fit

The 70 metre distance over Cat 6, 6a or 7 cable is the specification that determines whether this extender matches the site layout. If the cable run exceeds that limit, the video and USB link will not function. When the run is within range, the single-cable design with PoC delivers a complete 4K60 KVM extension without additional power outlets.

Questions about this item

Will this extender work with my older USB 2.0 keyboard and mouse?

Yes — the extender carries USB 1.1 HID signals, which are fully compatible with USB 2.0 keyboards and mice; the supplied USB 2.0 Type-A to Type-B cable connects the host computer to the transmitter.

How can I verify the link is running at 4K60 after installation?

Connect a 4K60-capable display to the receiver; the source device’s output settings should show 4K at 60 Hz with HDCP 2.3 active, and video should appear without flicker or downscaling.

What comes in the box and what must I supply?

The package includes the transmitter and receiver pair, one DC 12V 1A power adapter, one USB 2.0 Type-A to Type-B cable, four mounting brackets with screws, and the user manual; you must provide a Cat 6/6A/7 cable up to 230 ft and the HDMI cables for your source and display.
