Introduction
Key Digital®KD-4x1WUTx is an HDBaseT wall-plate transmitter + universal presentation switcher +
soft-codec enabling interface with two HDMI, one Display Port, and one USB-C input, as well as one
USB-A and USB-B connection. KD-X4x1WUTx is ideal for professional video installations in conference
rooms, class rooms, lecture halls, auditoriums, and more. KD-X4x1WUTx is natively received by KD-
X100MRx black box HDBaseT Rx or by KD-UPS52U Presentation Switcher. Both Rx options have audio
de-embedding for ease of integration with audio systems. Additional Key Digital Presentation Switchers
also support integration with KD-X4x1WUTx. KD-X4x1WUTx features push-button or TCP/IP switching
selection of the desired source and is KD-App Ready. Key Digital CEC Manager™enables basic controls
of the connected display for a simplistic all-in-one integration system. KD-X4x1WUTx is HDCP 2.2
compliant and supports 4K/UHD 24/25/30/60 (4:4:4) resolutions with up to 18Gbps bandwidth. 4K/
UHD signals are extended up to 100m / 328ft and 1080p up to 150m / 492ft via single CAT5e/6 cable.
In addition to AV signals, KD-X4x1WUTx extends USB 2.0, IR, RS-232 for controlling remotely located
equipment. The wall-plate unit fits in a standard US three-gang box and is powered by the Rx unit or
Presentation Switcher for convenient installation.

3. Connect HDMI displays / projectors to the HDMI output port of the RX unit / presentation switcher
4. Connect USB devices into desired USB A ports and USB host computer to desired USB B ports at
wall plate transmitter, HDBaseT Rx, or presentation switcher.
»a. Note: When using KD-UPS52U presentation switcher the connection location of the USB
devices and host is determined by the USB mode selection switch. Please refer to KD-UPS52U
Quick Setup Guide for more information.
5. Connect CAT5e/6 cabling to Tx and Rx unit / presentation switch. Use 568-B standard termination
on both ends. Avoid couplers and excess CAT cable length.
6. To send the selected audio source into audio systems, connect from the analog or digital audio de-
embed outputs of the Rx unit / presentation switcher
7. Connect control system or PC to LAN port of the KD-X4x1WUTx or the Rx for network connectivity
8. Connected monitors are controlled by CEC Manager
™
on the HDMI connection. Alternatively,
connect IR/RS-232 wiring from control system into pass-thru ports of KD-X4x1WUTx and IR/RS-232
ports of the Rx unit / Presentation Switch
9. Screw-in power supply to the KD-UPS52U or KD-X100MRx unit, and then connect power to outlets.

CONTROL:
Option 1: Control via Push Button
1. Display Control via CEC Manager
™
»a. Requires CEC supported display with CEC enabled
2. Input Select
»a. Advances through inputs 1, 2, 3 and 4 respectively
»b. Press and hold for 5 seconds to active Auto switching. Solid illumination of the button’s
backlighting indicates mode has been set
Option 2: Control via KD-App, Key Digital Management Software™
›KD-X4x1WUTx is controllable by:
»Key Digital’s user-friendly iOS App (downloadable in the App Store)
»Key Digital Management Software (downloadable here).
›Configuration Steps:
»Connect and configure KD- X4x1WUTx as described in this Quick Setup Guide.
»Download and open KD-App and/or KDMS
»Ensure the iOS device and/or PC computer are on the same network with KD-X4x1WUTx
»Perform a network scan in the KD-App/KDMS
»Select and control the selected KD-X4x1WUTx

8
Option 3: Control via professional control system
KD-X4x1WUTx allows control over TCP/IP interface for bi-directional communication. You may connect to
the LAN port of the KD-X4x1WUTx, KD-X100MRx, or KD-UPS52U to deliver network connectivity to the Key
Digital devices.
Default IP Address: 192.168.1.239, Port 23
›For TCP/IP control, the default static IP address is 192.168.1.239, with port 23
›RS-232 connection is used for control pass-thru to connected devices, not for unit control of the
KD-X4x1WUTx
›For the past 10 years, most Key Digital switches have supported a standard audio+video switching
command. KD-X4x1WUTx is also controllable by this command, so if you have previously integrated
Key Digital switches by third-party control systems you may have success using the same driver/
module.
