Introduction

Key Digital® KD-4x1WUTx is an HDBaseT wall-plate transmitter + universal presentation switcher + soft-codec enabling interface with two HDMI, one Display Port, and one USB-C input, as well as one USB-A and USB-B connection. KD-X4x1WUTx is ideal for professional video installations in conference rooms, classrooms, lecture halls, auditoriums, and more. KD-X4x1WUTx is natively received by KDX100MRx black box HDBaseT Rx 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-X4x1WUTx. KD-X4x1WUTx features push-button or TCP/IP switching selection of the desired source and is KD-App Ready. Key Digital CEC ManagerTM enables basic controls of the connected display for a simplistic all-in-one integration system. KD-X4x1WUTx 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-X4x1WUTx 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 Presentation Switcher for convenient installation.

CONNECT:

Begin with the KD-UPS52U unit, KD-X100MRx, KD-X4x1WUTx, USB camera (sold separately), all input/output devices, and the audio system powered off.

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

2. (Optional) Connect HDMI, Display Port, USB-C, VGA sources to presentation switcher (sold separately). Port connectivity varies by presentation switcher model.

3. Connect HDMI displays/projectors to the HDMI output port of the RX unit/presentation switcher

4. Connect USB devices into desired USB A ports and USB host computer to desired USB B ports at wall plate transmitter, HDBaseT Rx, or presentation switcher.
   • a. Note: When using the KD-UPS52U presentation switcher the connection location of the USB devices and host is determined by the USB mode selection switch. Please refer to the 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. Avoid couplers and excess CAT cable length.

6. To send the selected audio source into audio systems, connect from the analog or digital audio deemed outputs of the Rx unit/presentation switcher

7. Connect control system or PC to LAN port of the KD-X4x1WUTx or the Rx for network connectivity

8. Connected monitors are controlled by CEC ManagerTM on the HDMI connection. Alternatively, connect IR/RS-232 wiring from the control system into pass-thru ports of KD-X4x1WUTx and IR/RS-232 ports of the Rx unit / Presentation Switch

9. Screw-in power supply to the KD-UPS52U or KD-X100MRx unit, and then connect power to outlets.

10. Power on HDMI sources and displays, audio systems, connected computers, USB devices, and hosts

   • c. Gateway (default is 192.168.1.1)
   • d. Port (default is 23)
   • i. Note: If using KD-App, please do not change the port number.

6. Save (fig. 2d)
   

7. If using KD-App or KDMS for control, set the desired Input/Output names by entering the Input/ Output Settings section of the properties window, and selecting the Change Input/Output Name button (fig. 3a), selecting the desired input/output, and entering the name (fig. 3b)
   

8. Set the EDID rotary to position “A” for 4K video with 2ch audio. Choose setting “4” for 1080p video with 2ch audio. Refer to the Connections, Buttons, and LEDs section for more options and information.

9.  Set the Forced HPD to the ON position to fix a high HPD state to connected displays.

10. Additional settings may be adjusted in the KDMS software. Full access to all settings/commands is achieved via terminal session using Tera Term or PuTTy software.

11. Ensure that CEC is enabled on your displays/projectors. Depending on the manufacturer, HDMI-CEC may be given a different name. View THIS article for a list of CEC names and how to enable CEC on popular displays.

12. Your unit is now ready to control from the KDMS Control Panel, KD-App, or by the professional control system.

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, 3 and 4 respectively
   » b. Press and hold for 5 seconds to active Auto-switching. Solid illumination of the button’s backlighting indicates the mode has been set

Option 2: Control via KD-App, Key Digital Management Software™

• KD-X4x1WUTx 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- X4x1WUTx 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- X4x1WUTx
  • Perform a network scan in the KD-App/KDMS
  • Select and control the selected KD-X4x1WUTx
  

Option 3: Control via the professional control system
KD-X4x1WUTx allows control over the TCP/IP interface for bi-directional communication. You may connect to the LAN port of the KD-X4x1WUTx, 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
•  The RS-232 connection is used for control pass-thru to connected devices, not for unit control of the KD-X4x1WUTx
•  For the past 10 years, most Key Digital switches have supported a standard audio+video switching
  command. KD-X4x1WUTx 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)
  • SPO01SIyy – yy = input number (01-02)
  • SPOSIyy – yy = input number (01-02)
