Key digital KD-X444LP 4K 18G HDMI Over 70m CAT5e/6 Extender Set

Introduction

Key Digital® KD-X444LP 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- X444LP extends video resolutions up to 4096×2160 at 60hz with 4:4:4 chroma sub-sampling over a single CAT5e/6 cable up to 230ft (70m) or up to 328ft (100) when using CAT6A STP cabling. The Transmit unit features an HDMI pass- thru port for integration with local monitors or AV Receivers. In addition to HDMI AV, KD-X444LP carries IR or RS-232 for controlling remotely located equipment. An IR sensor and IR emitter are included with the IR Input port also supporting 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-X444LP 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.

Application Example

Quick Setup 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 your local monitor / AV Receiver to the HDMI pass-through port of the Tx 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.
  •  The Tx unit supports hard-wired / serial IR connections only with the following pinout
  •  The Rx units supports connection with the included IR Sensor only. Mount the sensor in a location to easily collect line of sight IR signals from remotes.
•  Connect RS-232 from your control system or computer.
  •  TxD from the Controller connects into RxD of the extender
  •  RxD from the Controller connects into TxD of the extender
  •  Ground from the Controller connects into Ground of the extender
• 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
•  Power on source and display

CONFIGURE

• EDID Handshake Selection (Tx Unit)
• The default EDID handshake setting is “A” (4Kx2K@60, 18G, HDR, 2ch audio).
•  Use the EDID rotary if you wish for your source to output a different video resolution and audio format
•  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-X444LP’s capabilities.

RS-232 / IR Selection Switch (Tx and Rx Unit)

• Used to select if IR or RS-232 control will be extended through the Rx unit
•  If RS-232 is selected, IR control is not extended.
•  If IR is selected, RS-232 is not extended
• If IR is selected both IR In and IR Out is active

Firmware Mode Switch (Tx and Rx Unit)

•  The switch should always be set to “Operate”
•  “F/W Load” should only be selected if loading firmware to the unit.
•  Firmware load/upgrade should only be done if advised by Key Digital Technical Support

Forced HPD Switch (Rx Unit)

• In cases of many connectivity layers or use with non-standard devices, hot plug detection (HPD) may be lost or drop below standard 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 forced 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

LED Indicator Lights

• Power: Color – Blue
  •  Solid illumination during power on state, as provided by healthy connection with power supply and healthy PoC extension.
  •  Steady blink if unit has is has a power short
•  Live: Color – Yellow
  •  Steady blink from healthy unit CPU state
•  Video: Color – Orange
  •  Illumination with active signal from source
  •  Off with no signal for source
•  HDMI Link: Color – Blue
  •  Tx Unit: Solid illumination from active signal from connected source
  •  Tx Pass-Through: Solid illumination from active Hot Plug Detection voltage with connected display/output device
  •  Rx Unit: Solid illumination from active Hot Plug Detection voltage with connected display/ output device

Rack Mounting
In addition to mounting with the supplied L-Brackets, multiple KD-X444LP units may be mounted in KD-SMS16 using the side mounting screws. KD-SMS16 is a mounting shelf for Key Digital units with side mounting screw spacing of 2.912”, 2.582”, or 2.252”. Do NOT exceed 12 units as doing so will result in unit damage by overheating.
