Key Digital X444SP Overview
The KD-X444SP 4K HDMI over Cat 5e/6 Extender Set from Key Digital is a 4K 18 Gb/s, HDCP2.2 compliant HDMI over Cat 5e/6 transmitter and receiver set for the extension of digital video signals with the latest standards in resolution, HDR, and chroma over a single Cat cable with video resolutions up to 4096 x 2160 at 60 Hz with 4:4:4 chroma subsampling for up to 164'.
The KD-X444SP carries IR or RS-232 for controlling remotely located equipment. An IR sensor and IR emitter are included, and the transmitter's IR input port supports serial IR input directly from a control system/IR block. Using its Power over Cat (PoC) capability, only one power supply is needed, and it may be connected at either unit for ease of installation.
The system 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 reclocking for installation with long cabling or many connectivity layers.
