DIGITUS DS-55522 — uncompressed 4K/60Hz HDMI and KVM over one Cat cable
4K/60Hz 4:4:4KVM (USB)Up to 150 mPower over Cable
The DIGITUS 4K HDBaseT HDMI KVM Extender Set (part DS-55522) is a transmitter and receiver that send uncompressed HDMI 2.0b video at 4K/60Hz 4:4:4 with HDR, USB keyboard/mouse and bi-directional IR over one Cat6A, Cat7 or Cat8 cable — up to 120 m at 4K and 150 m at 1080p — for operating a PC in a server room or rack from a desk, classroom or control station.
Thanks to Power over Cable (PoC), only one unit needs a power supply; the other is powered through the Cat cable. An EDID switch on the transmitter lets you copy the display EDID or force a standard 1080p mode when a source misbehaves.
Before you order: 4K/60Hz reaches 120 m; the 150 m figure applies to 1080p. Use Cat6A or better and run the cable directly between the units — not through a network switch.
What's in the Box
- Transmitter (TX) and receiver (RX)
- IR transmitter cable (1.5 m) and IR receiver cable (1.5 m)
- Power supply 24 V / 1 A (1.15 m)
- USB cable (1.5 m)
- Mounting material
- Manual
What It Means in Practice
- Keep the PC in a locked rack and work from up to 120 m away at 4K, with keyboard and mouse on the receiver.
- Only one socket needed: power either end and PoC feeds the other unit.
- Uncompressed HDBaseT means no compression artefacts or added streaming delay, unlike IP extenders.
- IR in both directions lets you control the source from the display end, or the display from the source end.
What Will Not Work
- No local HDMI loop-out, RS-232 or LAN pass-through is published for this set.
- USB is 1.1 for keyboard and mouse only — not for USB drives or webcams.
- Not for routing through switches or patching over an existing LAN.
- 4K at 150 m is not supported — for longer distances use a fibre set such as DS-55348.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
DS-55522 is our choice when a desk or lectern is within about 120 m of the PC and you want a real-time, uncompressed 4K picture with keyboard and mouse. The cable is critical — use solid-copper Cat6A or better from our network cables.
✓ Buy it if you want uncompressed 4K/60Hz HDMI plus USB keyboard/mouse up to 120 m over one Cat6A cable.
✕ Skip it if you need more than 150 m, RS-232, a local HDMI out or USB beyond keyboard/mouse.
→ Also consider DS-55348 for fibre KVM over kilometres.
