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.
KD-X444SP extends video resolutions up to 4096×2160 at 60hz with 4:4:4 chroma
sub-sampling over a single CAT5e/6 cable up to 164ft (50m). 1080p resolutions
are extended up to 230ft / 70m.
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.

Quick Connection Guide
Begin with the Tx and Rx units and all input / output devices turned off with power cables removed
- Connect your HDMI source to the input port of the Tx unit.
- Connect your HDMI display to the output port of the Rx unit.
- Connect a CAT5e/6 cable between Tx and Rx unit. Use 568-B termination.
- Connect IR emitter from the IR Out port of the Tx or Rx unit and mount over the IR receptor of the device you wish to control.
- IR Input is specific on the Tx and Rx unit.

EDID Management Rotary
Use the EDID rotary if you wish for your source to output a different video
resolution and audio format
- The default EDID handshake setting is “A” (4Kx2K@60, 18G, HDR, 2ch audio).
- If setting 0 is selected, the Rx unit collects the EDID handshake from the connected display and a handshake is provided to the source that is similar to the EDID file of the display, but within KD-X444SP’s capabilities.
- Although it is not necessary, power cycling the Tx unit and HDMI source may help the detection of the newly selected handshake.

Forced HPD Switch Troubleshooting tool to help overcome installation
obstacles.
- In cases of many connectivity layers or use with non-standard devices, hot plug detection (HPD) voltage may be lost or drop below detectable levels and lead to a “no source connected” error message and/or no image on the connected display.
- If set to ON, Hot Plug Detection (HPD) voltage is fixed at the HDMI connection of the Rx unit. The connected display will be fed a constant voltage to inform the device that a partner is always connected and active.
- If set to OFF, Hot Plug Detection (HPD) voltage is passed thru from connected source to the display
