4K60 & Ultrawide HDMI KVM Extender with USB 3.2 over CAT6a (40m/130ft)
Put the Workstation in the Rack and Everything Else on the Desk — 4K60 4:4:4, 32:9 Ultrawide Support & USB 3.2 at 2.5Gbps
Puts the workstation in the rack and everything else on the desk — over one CAT6a cable. The EXT-HDMIKVM4K-40M extends uncompressed 4K60 4:4:4 video, USB 3.2 Gen 1 peripherals at 2.5Gbps, analog audio and RS-232 up to 40m/130ft, so the host machine can live in a conditioned closet while the display, keyboard, mouse, camera and drives stay at the operator position. Both units are metal-enclosed, draw 29.4W combined, and run from a single 24V supply connected at either end via bi-directional PoC — the right choice for control rooms, edit bays and clinical workstations where USB peripheral performance matters more than raw cable distance.
An HDMI loop out on the transmitter drives a local monitor at the same time the receiver drives the remote display, and three downstream ports at the far end — two USB-A and one USB-C — take modern peripherals without adapters. Ultrawide operator desks are supported natively at 5120×1440 (32:9) and 3440×1440 (21:9), both at 60Hz 4:4:4. RS-232 pass-through, an ASCII command set and 25 EDID presets make it specifiable into a control system rather than a fixed point-to-point link. Its defining advantage is USB bandwidth: at 2.5Gbps it carries more than five times what USB 2.0 extension delivers, which is the difference between a 4K room camera or an external drive working at the far end and not.
- Extends uncompressed 4K60 4:4:4 HDMI video and USB 3.2 Gen 1 data up to 40m/130ft over a single CAT6a cable
- USB 3.2 Gen 1 at up to 2.5 Gbps — more than 5× the bandwidth of USB 2.0 extension (does not support 5 Gbps operation)
- HDMI loop out on the transmitter drives a local monitor simultaneously with the remote display
- Three downstream USB device ports on the receiver — 2× USB-A and 1× USB-C, 5V/1.5A per port
- Ultrawide support — 5120×1440 (32:9) and 3440×1440 (21:9) at 60Hz 4:4:4; 5120×2160 at 50Hz
- HDCP 2.3 and HDCP 1.x, with HDR, HDR10, HDR10+, Dolby Vision and HLG pass-through
- RS-232 pass-through plus ASCII command API and 25 EDID presets for control-system integration
- Analog audio de-embedding at both transmitter and receiver via 3.5mm output (LPCM 2CH, 32–192kHz)
- Bi-directional 24V PoC — one power supply at either end powers both units over the CAT6a cable

Hi, I'm Eric from KanexPro. Put the workstation in the rack, and everything else on the desk, over one CAT6a cable. This KVM extender carries 4K60 4:4:4 and ultrawide video, with USB 3.2 at 2.5 gigabits, up to 40 meters. That's over five times USB 2.0, so a 4K camera, a touch panel or a drive works at the desk. Here's how it connects. In the rack, the workstation plugs into HDMI IN and USB HOST, and a rack monitor runs off LOOP OUT. One CAT6a cable runs up to 40 meters to the receiver at the desk. One 24 volt supply, at either end, powers both units over that cable. At the desk, the receiver's HDMI output drives the display, up to 5120 by 1440. Next, USB, audio and control. The keyboard and mouse go on the USB-A ports, and a 4K USB camera on the USB-C port, with no adapter. Audio comes out at the desk on a 3.5 millimeter jack. And a control system connects on RS-232, with an ASCII command set. Built for desks where the computer doesn't belong. Control rooms: quiet desks, workstations cooled in the rack. Edit bays: fast drives and cameras at the desk. Clinical workstations: the PC in a closet. Classrooms and labs: the camera at the lectern. Now, the key features. USB 3.2 at 2.5 gigabits: cameras, touch panels and drives work at the desk. 4K60 4:4:4, uncompressed, with ultrawide displays up to 5120 by 1440. Loop out: a monitor in the rack and the display at the desk, at once. 40 meters over one CAT6a cable, with one 24 volt supply for both ends. For integrators: RS-232 pass-through, an ASCII command set, and audio out at both ends. Spec it wherever the workstation belongs in the rack. Thanks for watching. I'm Eric from KanexPro. See you next time.
