Introduction
KD-PS22UTx is an HDBaseT transmitter + presentation switcher + soft-codec enabling interface with
two HDMI inputs, as well as two USB-A connections, and one USB-B connection. The KD-PS22UTx also
includes a local pass-through output for an additional display. KD-PS22UTx is ideal for professional
video installations in conference rooms, classrooms, lecture halls, auditoriums, as well as audio return
/ ARC applications. KD-PS22UTx is natively received by KD-X100MRx black box HDBaseT Rx or by
KD-UPS52U Presentation Switcher. The KD-PS22UTx and both Rx options have audio de-embedding
for ease of integration with audio systems. Additional Key Digital Presentation Switchers also support
integration with KD-PS22UTx. KD-PS22UTx features push-button or TCP/IP switching selection of
the desired source and is KD-App Ready. KD-PS22UTx 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-PS22UTx extends USB 2.0, IR, RS-232, and LAN for controlling remotely located equipment.

KD-PS22UTx, HDBaseT Rx, or presentation switcher.
»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, avoiding 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 KD-PS22UTx / Rx unit / presentation switcher

CONTROL:
Option 1: Control via Push Button
›Input Select
»a. Alternates between Inputs 1 and 2
»b. Auto Switching is enabled via Control rotary
Option 2: Control via KD-App, Key Digital Management Software™
›KD-PS22UTx 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-PS22UTx 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-PS22UTx
»Perform a network scan in the KD-App/KDMS™
»Select and control the selected KD-PS22UTx

Option 3: Control via professional control system
KD-PS22UTx allows control over TCP/IP interface for bi-directional communication. You may connect to
the LAN port of the KD-PS22UTx, 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-PS22UTx
›For the past 10 years, most Key Digital switches have supported a standard audio+video switching
command. KD-PS22UTx 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.
