KD-UPS52U
Key Digital®KD-UPS52U is a 4K/18G KD-App Ready universal presentation switcher + soft-codec
enabling interface with CEC Manager™, auto switching, and audio de-embedding creating a user-
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, 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 will enable an app-ready all-in-one solution for control of video switching
with sound and speech enforcement. Key Digital CEC Manager™enables basic controls
of the connected displays for a simplistic all-in-one integration system. KD-UPS52U
presentation switcher supports all SD, HD, VESA and Ultra HD/4K video standards with
HDR header information included in a variety of 4K EDID handshakes. In addition to IR,
RS-232, and TCP/IP control, KD-UPS52U can also be controlled via trigger voltage and features status-
monitoring LEDs.

Option 3: Control via professional control system
KD-UPS52U allows control over serial interface for bi-directional communication.
Pin: 1 2 3 4 5 6
›For RS-232 control use pins 4, 5, and 6 of the Main Control port
›For TCP/IP control, the default static IP address is 192.168.1.239, with port 23
Default static IP address:
192.168.1.239, port 23
›For the past 10 years, most Key Digital matrix switches have supported a standard audio+video
switching command. KD-UPS52U is also controllable by this command, so if you have previously
integrated Key Digital matrixes by third-party control systems you may have success using the same
driver/module.
»Switching – Video + Audio together (two commands supported)
»SPO01SIyy yy = input number (01-02)
»SPOSIyy yy = input number (01-02)
