introduction

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. 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 control system / IR block. With Power over CAT (PoC), only one power supply is needed, and it may be 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 reclocking for installation with long cabling or many connectivity layers.

Features

  • Single CAT5e/6 UTP/STP Extension: Fully automatic equalization, and amplification depending on cabling length

  • 4K Resolution Support: 4096x2160 or 3840x2160 24/25/30/60hz at 4:4:4 (signals up to 18Gbps bandwidth)

  • Flexible Power over CAT (PoC): Only one power connection needed. Tx may power Rx, or Rx may power Tx.

  • Visually Lossless Compression: 18G enabling technology applied to all video formats exceeding 10.2Gbps to accommodate transmission channel

  • Low Profile: Super slim chassis design 

  • Signal Extension: For resolution and cable quality

    • 4K/UHD (18G) / 4K 10G / 1080p with CAT5e/6: Up to 164ft / 50m 

  • 10G Pass-thru: Mode enables uncompressed 10.2Gbps signal extension. 

  • HDR10 (High Dynamic Range): More life-like images through a greater range of luminance

  • HDCP 2.2: Compliancy up to HDCP 2.x and backward compliant 

  • Deep Color Support: Up to UHD/4K 30Hz 4:4:4/12 bits or 60Hz 4:4:4/8 bit 

  • IR Sensor: Sensor powering via +5V on IR In ports collects line-of-sight IR from remote(s) without external IR connecting block 

  • Up/Down IR: Two channels of IR enable control to/from devices or control systems connected to Tx and Rx units 

  • RS-232: Bi-Directional control to/from Tx and Rx unit on Phoenix connector

  • Full Buffer Technology: Key Digital’s proprietary suite of EDID, HDCP, TMDS, and HPD management to overcome Pro AV installation obstacles.
