About 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 transmitters, KD-X4x1WUTx, or KD-X3x1WUTx, or table mounted KD-PS22UTx (each 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 connected 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 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.

Quick Setup Guide

Begin with the KD-UPS52U and KD-X100MRx, KD Transmitter (sold separately), all source, display devices, audio system, and any other connected peripherals powered off.

Connect

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

a. Note: For USB-C, cable must be USB-C 3.2 Gen 2 to support AV at the needed bandwidth.
b. (Optional) Connect HDMI, Display Port, USB-C, VGA sources to wall plate / table transmitter (sold separately). Port connectivity varies by transmitter model.

1. Connect video displays/projectors to the HDMI output ports of KD-UPS52U and/or KD-X100MRX
2. Connect USB hosts and devices. For USB camera, microphone, speakers, audio DSP, 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 Transmitter.

a. USB devices must be connected at same location, see USB Modes Selection Table.
b. Ensure USB toggle switches have chosen USB Device or Host as desired.

1. Connect CAT5e/6 cabling from KD-UPS52U's HDBaseT outputs to KD-X100MRX HDBaseT input and (optional) from KD-UPS52U's HDBaseT input to transmitter (sold separately)
2. Connect audio to send audio of the select source into KD-Amp220 use KD-UPS52U's analog audio de-embed port. For other audio systems use the digital or analog outputs ports located on KD-UPS52U or KD-X100MRx.
3. (Optional) Connect RS-232 wiring for Integrated System. If utilizing KD-AMP220 or KD-CAMUSB integration control mode, connect RS-232 wiring from KD-UPS52U Unit Control TxD and Ground pins into KD-AMP220 and KD-CAMUSB RxD and Ground. Using a stripped mono or stereo audio cable is recommended, but other cables will work as well. See below diagram
4. Connect Control System. For KD-App control and/or IP control from a control system or PC, connect TCP/IP port to network. RS-232 and IR control may also be utilized, but IP control is required for KD-CamUSB and KD-Amp220 integrated systems.
5. (Optional) Connect display/projector's IR/RS-232 from control system into pass-thru ports of KD-UPS52U and IR/RS-232 ports of the KD-X100MRX.

a. Alternatively, KD-UPS52U CEC Manager features can send power on and off commands via CEC on the HDMI connection.

1. Connect power. Screw-in power supply to the KD-UPS52U unit, and then connect power to outlets.
2. Power on sources, displays, audio systems, connected computers, USB devices and hosts to use system.

Option 3: Control via professional control system

KD-UPS52U allows control over serial interface for bi-directional communication.

• For RS-232 control use pins 4, 5, and 6 of the Unit 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.

a. Switching Video + Audio together (two commands supported)

i. SPO01SIyy yy = input number (01-05)
ii. SPOSlyy yy = input number (01-05)

b. Display CEC On / Off

i. SPOxxTVy xx = output number (01-02), y = ON or OFF

• See the TCP/IP and RS-232 Commands section for full command set.

Test for proper operation of the unit and cables in your system before permanently securing the unit for final installation. Ensure that you leave enough ventilation space to provide sufficient airflow and cooling

EDID Handshaking Rotary

• EDID authentication is provided from the unit to the connected inputs/sources.
• Inputs/sources connected to a KD Transmitter receive their EDID handshake from the KD Transmitter
• The EDID file (AKA "handshake" is selected using the EDID rotary and provides a list of compatible video and audio formats as well as digital data, informing the source device what it should outputs.
• Most sources will comply with a new EDID file without a power-cycle, but devices do behave differently
• Adjustments may speed up sync time during source selection
