About KD-XWPS
Key Digital® KD-XWPS is a single-gang wall-plate switcher transmitter + receiver kit with one HDMI and one
USB-C input ideal for professional AV systems installations in conference rooms, huddle spaces, classrooms,
and more. KD-XWPS supports 4K/UHD resolution with bandwidth up to 18Gbps and HDCP2.2 compliancy and
extends video resolutions up to 4096x2160 at 60hz with 4:4:4 chroma sub-sampling over a single CAT6/6A
cable up to 164ft (50m). In addition to HDMI video and audio signals, KD-XWPS features an IR sensor on the
faceplate to control remotely located equipment. KD-XWPS features EDID handshake control and hot plug
detection for overcoming common systems integration obstacles. The wall-plate unit fits in a standard US
single-gang box and is powered by the Rx unit for convenient installation.

Quick Setup Guide
BeginwiththeTxand Rxunitsand allinput /outputdevicesturned offwith powercables removed.
Connect
1. Connect video sources into the HDMI and USB-C input ports of KD-XWPS TX
a. For USB-C, the cable must be USB-C 3.2 Gen 2 to support AV at the needed bandwidth
2. Connect video displays/projectors to the HDMI output port of Rx
3. If collecting IR control signals at the wall plate, connect IR emitter to Rx’s IR Out port and secure the
emitter head to the IR sensor of the device you wish to control.
a. Connect CAT6 cable from KD-XWPS TX’s RJ45 output port to the RX units RJ45 input. Use
568-B termination. Do not connect the Tx or Rx units to third-party devices, including HDBaseT.
Damage will occur and warranty will be voided.
4. Connect power. Screw-in power supply to the Rx unit, and then connect power to outlet.
Control
•Use the Input Select button to toggle between the HDMI or USB-C source inputs or
to activate Auto Switch mode
•Press and hold for 3 seconds to activate Auto Switching. Solid illumination of the
backlighting indicates mode has been set
Test for proper operation of the unit and cables in your system before permanently securing the
unit for final installation. Ensure that you leave enough ventilation space to provide sufficient
airflow and cooling

Service USB Port
•Micro USB port
•Used for firmware updates (consult with Key Digital tech support before updating
firmware)
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 (Rx only)
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
RS-232 and IR In ports (Rx only)
The ports do not have any connection to the Tx unit and therefore have no
functionality in the KD-XWPS kit.

Rack Mounting
In addition to mounting with the supplied L-Brackets, multiple Rx units may be mounted in KD-SMS16 using the
side mounting screws. KD-SMS16 is a mounting shelf for all 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.
