DIGITUS 4K HDMI HDBaseT 2.0 KVM Extender Set, up to 100m over CAT6A, 4K/60Hz 4:2:0, USB 2.0 for 6 Devices

The DIGITUS DS-55505 is a 4K HDMI HDBaseT 2.0 KVM extender set that carries video, audio and USB 2.0 over a single CAT6A/7/8 cable up to 100 m, for control rooms, reception desks, digital signage and workstations where the computer must stay in a server room or locked cabinet. A transmitter connects to the computer, a receiver drives the display and USB devices at the far end.

Video is uncompressed up to 3840 x 2160 at 60 Hz with 4:2:0 chroma subsampling, plus 4096 x 2160 at 24 Hz, 1080p and Full 3D. The USB link is Hi-Speed USB 2.0 for up to six devices, so a keyboard, mouse, touch screen, barcode scanner or webcam can sit beside the display. HDCP 2.2 and CEC are supported, and audio passes through as LPCM 7.1 or compressed DTS, Dolby Digital, DTS-HD Master Audio and Dolby TrueHD.

• 1 x HDBaseT 2.0 KVM extender set (transmitter + receiver)
• 2 x power supply 12 V / 2 A (100-240 V AC)
• 1 x USB connection cable, 1.5 m
• 4 x wall-mounting brackets

• Keep noisy or valuable PCs in the server room and leave only a screen, keyboard and mouse at the desk or kiosk.
• One network cable carries everything, so there is no separate USB extender or audio cable to install.
• 4K at 60 Hz is delivered with 4:2:0 colour, which looks sharp for video, dashboards and signage; small coloured text can look softer than with a direct 4:4:4 connection.
• USB 2.0 Hi-Speed handles touch screens, scanners, card readers and webcams, not just keyboard and mouse. Connect the transmitter to the computer with the included 1.5 m USB cable.
• Plan power outlets at both ends: the transmitter side draws about 3 W and the receiver side about 7 W, each from its own 12 V adapter with a 1.2 m lead.
• Both units need mains power; each comes with its own 12 V power supply in the box.
• Metal housings and the included wall brackets let you fix the units behind a display, under a desk or inside a rack shelf.
• Run the cable point to point between the two units, with no switch or patch panel electronics in between; passive patch panels are fine if the total stays within 100 m.

• It is not a network device: the HDBaseT link cannot pass through an Ethernet switch, router or IP network.
• It does not carry 4K/60Hz 4:4:4 or HDR; the published path is HDMI 1.4 at 10.2 Gbps with 4:2:0 subsampling only.
• There is no PoE or power over cable: both transmitter and receiver must be powered locally.
• IR and RS232 control pass-through are not published, so do not plan on controlling a TV or projector through this set.
