DIGITUS DS-55526 — 4K HDBaseT HDMI KVM Extender Set up to 150 m
4K/60 up to 120 m1080p up to 150 mUSB 2.0 KVM + IROne power supply (PoC)
The DIGITUS DS-55526 is a transmitter and receiver set that extends HDMI video, audio, USB 2.0 and infrared over a single network cable using HDBaseT — so a PC can stay in a server room or rack while the screen, keyboard and mouse sit up to 150 m away in a control room, reception, classroom or digital-signage location.
It carries 4K at 60 Hz 4:4:4 (HDMI 2.0b, HDCP 2.2, 18 Gbps, HDR10/HDR10+/Dolby Vision/HLG) up to 120 m and 1080p at 60 Hz up to 150 m. The receiver has two USB 2.0 ports for keyboard, mouse, webcam, storage or a touch panel, and bidirectional IR lets you control the source or display remotely. Power over Cable (PoC) means only one unit needs the supplied 24 V power supply.
Before you order: This is a point-to-point extender over a direct cable run — it does not work through Ethernet switches or over an IP network. DIGITUS recommends Cat6A or better cable for full distance.
What's in the Box
- Transmitter and receiver
- 24 V / 1 A power supply (one is enough thanks to PoC)
- IR transmitter cable 1.5 m and IR receiver cable 1.5 m
- USB cable 1.5 m
- Mounting material
- Operating instructions
- No network or HDMI cables
What It Means in Practice
- Keep a noisy PC or media player in the rack and work at a quiet desk or wall display up to 150 m away, with full keyboard/mouse control.
- 4K at 60 Hz with HDR reaches 120 m — enough for most building runs; beyond that, use 1080p for the full 150 m.
- Touch screens work: the USB back channel carries touch input to the PC.
- The EDID switch on the transmitter lets you copy the display's EDID or force a safe 1080p/2-channel profile when a display behaves oddly.
- Metal, wall-mountable units (65 × 140 × 18 mm each) fit behind displays and in cabinets.
What Will Not Work
- Cannot run through a switch, patch to multiple screens or stream over IP — one transmitter to one receiver only.
- Not powered by PoE from a network switch; it uses the supplied 24 V adapter and PoC between the units.
- No RS-232 control channel is published.
- 4K/60 is limited to 120 m; longer runs need 1080p or a fibre extender.
- Not compatible with HDBaseT units from other brands unless confirmed — buy the set.

Frequently Asked Questions
Can I use my existing building network cabling?
Yes, if it is a direct, uninterrupted Cat6A (or better) run between the two points — no switch or active equipment in between.
Do I need two power supplies?
No. One supplied 24 V adapter powers both units via Power over Cable.
Will a touch screen work at the far end?
Yes, touch panels on the receiver's USB ports send input back to the PC.
Singular Expert Insight · Buyer's Guide

✓ Buy it if you need 4K or 1080p display plus keyboard/mouse/touch up to 150 m from the PC over one cable.
✕ Skip it if you need to send video to multiple displays or over a switched IP network.
→ Also consider an HDMI-over-IP extender set if you need to pass through network switches.
