About KD-X444SP
Key Digital® KD-X444SP is a 4K/UHD 18Gbps, HDCP2.2 compliant HDMI over CAT5e/6 Transmitter plus
Receiver set for extension of digital video signals with the latest standards in resolution, HDR, and Chroma
over a single CAT cable.

single CAT5e/6 cable up to 164ft (50m).
In addition to HDMI AV, KD-X444SP carries IR or RS-232 for controlling remotely located equipment. An IR
sensor and IR emitter are included, and the Tx unit’s IR Input port supports Serial IR input directly from a

connected at either unit for ease of installation.
KD-X444SP features Key Digital’s proprietary Full Buffer Technology software suite, with EDID handshake
management, fixed hot plug detection, HDCP authentication to the connected source, and TMDS signal re-
clocking for installation with long cabling or many connectivity layers.
