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.

Application Diagram

Quick Connection Guide

Begin with the Tx and Rx units and all input / output devices turned off with power cables removed

1. Connect your HDMI source to the input port of the Tx unit.
2. Connect your HDMI display to the output port of the Rx unit.
3. Connect a CAT5e/6 cable between Tx and Rx unit. Use 568-B termination.
4. 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.
5. IR Input is specific on the Tx and Rx unit.
   a. The Tx unit only supports hard-wired / serial IR connections with the following pinout (the IR sensor may not be connected into the TX unit):

b. The Rx units supports connection with the included IR Sensor only (hard- wired / serial IR inputs are not supported). Mount the sensor in a location to easily collect line of sight IR signals from remotes.

6. Connect RS-232 from your control system or computer.
   a. TxD from the Controller connects into RxD of the extender
   b. RxD from the Controller connects into TxD of the extender
   c. Ground from the Controller connects into Ground of the extender

7. BEFORE connecting power supply to power outlet, screw-in the power supply to the Tx or Rx unit.
   AFTER all connections are made, plug-in power supply to power outlet

8. Power on source and display

CAT6/A Output and Input Connect Tx unit’s CAT6/A Output port to Rx unit’s CAT6/A Input port using CAT5e/6 UTP or STP in 568-B termination.

• 4K/UHD (up to 18Gbps) extension up to 164ft / 50m
• 1080p and lower resolutions extended up to 230ft / 70m
• Supports Dolby®, DTS (5.1 formats max)
• Connect to KD-X444SP only. Damage will occur if connected to non-KD-X444SP products and warranty will be void.

IR, RS-232 Ports and Selection Switch Select RS-232 or IR control extension as desired. RS-232 and IR may not be extended simultaneously.

• If IR is selected, both IR In and IR Out ports may be utilized simultaneously.

• The Tx unit’s IR In supports a hard-wired / Serial IR from a control system / IR block only (the IR sensor may not be connected into the TX unit). The incoming IR signal is output on the Rx unit’s IR Out port.
  o Use a 3.5mm Mono cable to connect into the Tx unit’s IR In port: IR In| Tip| Ring| Sleeve
  ---|---|---|---
  Serial IR| IR In| N/C| Ground

• The RX units IR In supports connection with the included IR sensor only (hard-wired / serial IR input signals are not supported). The incoming IR signal is output on the Tx unit’s IR Out port.
  o The IR Sensor receives signals from a 90° angle at up to 30 ft. away. It accepts a maximum IR burst frequency of 55kHz.

• TX & Rx unit IR Out Port outputs IR signal with a driving power of 5V with 32mA minimum current.

• RS-232 control extension:
  o TxD from the Controller connects into RxD of the extender
  o RxD from the Controller connects into TxD of the extender
  o Ground from the Controller connects into Ground of the extender

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

USB Service Port, Operate / FW Load Switch Used for firmware updates only.

• Ensure that the Firmware Mode switch is set to Operate on the Tx and Rx units for proper functionality.
• Consult with Key Digital Technical Support (tech@keydigital.com) before upgrading firmrware.
• USB to RS-232 interface required. Not included.

Power Connection
