soft-codec enabling interface with HDMI, Display Port, and VGA inputs, as well as USB-A and USB-B
connections. KD-X3x1WUTx is ideal for professional video installations in conference rooms, class
rooms, lecture halls, auditoriums, and more. KD-X3x1WUTx is natively received by KDX100MRx 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-
X3x1WUTx. KD-X3x1WUTx features push-button or IP switching and is KD-App Ready. CEC Manager™
keypad enables basic controls of the connected display for a simplistic all-in-one integration system.
KD-X3x1WUTx 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-X3x1WUTx 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

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 and 3 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-X3x1WUTx 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- X3x1WUTx 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-X3x1WUTx
»Perform a network scan in the KD-App/KDMS
»Select and control the selected KD-X3x1WUTx

8
Option 3: Control via professional control system
KD-X3x1WUTx allows control over TCP/IP interface for bi-directional communication. You may connect to
the LAN port of the KD-X3x1WUTx, 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-X3x1WUTx
›For the past 10 years, most Key Digital switches have supported a standard audio+video switching
command. KD-X3x1WUTx 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.
»Switching – Video + Audio together (two commands supported)
