KD-UPS52U

Key Digital® KD-UPS52U is a 4K/18G KD-App Ready universal presentation switcher + soft-codec
enabling interface with CEC Manager
friendly, simplified presentation system. KD-UPS52U features two HDMI, 1 Display Port, one USB-C,
and one HDBaseT input which integrates natively with universal presentation + USB switching wall plate
transmitter, KD-X4x1WUTx (sold separately). KD-UPS52U also features two USB-A and one USB-B
connectors, enabling connected laptops and computers to connect with web cams, USB microphones,
touchscreen displays, conferencing DSPs, and more. Mirrored HDMI and HDBaseT outputs enable
audience + presenter views and the HDBaseT output marries in with the included KD-X100MRx for
integrating monitors or projectors up to 100m / 328ft away when the selected source is outputting 4K/
UHD (up to 150m / 492ft at 1080p). Designed for professional audio video installations in conference
rooms, board rooms, classrooms, lecture halls, auditoriums, and more, KD-UPS52U enables multiple
video sources to be displayed on up to two connected displays while analog (balanced/unbalanced) and
digital (PCM) audio de-embed ports feed audio of the selected source into an amplifier, DSP, or sound
bar. Integrating KD-UPS52U with KD-AMP220 and KD-CAMUSB will enable an app-ready all-in-one
solution for control of video switching, sound and speech enforcement, and PTZ camera control. Key

to provide sufficient airflow and cooling.

Begin with the KD-UPS52U unit, KD-X100MRx, Key Digital wall-plate transmitter (sold
separately), all input/output devices, and audio system powered off.

1. Connect HDMI, Display Port, and USB-C sources to the input ports of KD-UPS52U unit

2. (Optional) Connect HDMI, Display Port, USB-C, VGA sources to wall-plate transmitter (sold separately).

Port connectivity varies by wall plate model.

3. Connect HDMI displays / projectors to KD-UPS52U’s HDMI output and the HDMI output port of

KD-X100MRX unit

4. For USB camera, keyboard, or mouse integration, connect USB devices into desired USB A ports and

USB host computer to desired USB B ports at KD-X100MRx, KD-UPS52U, or KD-X4x1WUTx

(optional) from KD-UPS52U’s HDBaseT input to wall-plate transmitter (sold separately)

6. To send the selected audio source into audio systems, connect from the analog or digital audio de-

embed outputs of KD-UPS52U, KD-X100MRx.

7. To embed audio into a USB host computer’s soundcard or into the KD-UPS52U connect USB

microphones or audio DSPs to USB device ports, and connect the Host computer to the USB Host
ports of KD-X100MRx, KD-UPS52U, or KD-X4x1WUTX. USB devices must be connected at same
location, see USB Modes Selection Table for more information.

8. If utilizing KD-AMP220 or KD-CAMUSB integration control mode, connect RS-232 wiring from KD-

UPS52U TxD and Ground into KD-AMP220 and KD-CAMUSB RxD and Ground.
