Introduction
Key Digital®KD-2x1WDTx / KD-X2x1WVTX are HDBaseT wall-plate transmitters + presentation
switchers with one HDMI and one Display Port / VGA input, ideal for professional video installations in
conference rooms, huddle spaces, class rooms, and more. KD-X2x1WDTx / KD-X2x1WVTX is natively
received by KD-X40MRx black box HDBaseT Rx or by KD-PS42 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-X2x1WDTx and KD-X2x1WVTX. KD-2x1WDTx /
KD-X2x1WVTX 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 40m / 131ft and 1080p up to 70m / 230ft via
single CAT5e/6 cable. In addition to AV signals, KD-X2x1WDTx / KD-X2x1WVTX extends IR and RS-232
for controlling remotely located equipment. The wall-plate unit fits in a standard US dual-gang box and
is powered by the Rx unit / presentation switch or Presentation Switcher for convenient installation.

Quick Setup Guide
Rx UNITS SOLD SEPARATELY. Go to http://www.keydigital.com/category_Presentation.html
for compatible Rx models.
CONNECT:
Begin with the Tx, Rx unit / presentation switch, and all input/output devices turned off with power
cables removed. Ensure that all desired functionality is achieved before installing units.
1. Connect HDMI and/or Display Port / VGA with analog audio sources to the input port(s) of the Tx unit
2. Connect HDMI display to the output port of Rx unit / presentation switch
3. 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
4. If controlling external devices or collecting a hard-wired IR signal, connect to the rear Phoenix
connectors from your control system.
5. To send audio of the selected source into audio systems, connect from the audio de-embed outputs
of the Rx unit / presentation switch.
6. BEFORE connecting power supply to power outlet, secure power into screw connector on Rx unit /
presentation switch
7. AFTER all connections are made, plug-in power supply to power outlet
8. Power on input/output devices

Use with third-party HDBaseT Tx or Rx
KD-X2x1WDTx and KD-X2x1WVTx are NOT compatible with third-party HDBaseT or
other Key Digital HDBaseT products, because of their unique PoH (Power over
HDBaseT) feature
Unit Configuration with KDMS
™
Pro
KD-X2x1WVTX’s video scaling features are most easily configured using Key Digital®Management
Software™Pro (KDMS™Pro) that can be downloaded here: https://goo.gl/ZcyHui
KD-X2x1WDTx also may be configured used KDMS™Pro, however most settings are easily accessed using
the physical rotaries and slide switches on the unit.
1. Connect to KD-X2x1WVTx / KD-X2x1WDTx from
your PC using the USB micro port on the face of
the unit
2. Open the Key Digital®Management Software™Pro software and perform a USB scan (fig. 1a)
3. Choose the detected device from the Devices window (fig. 1b)
4. In the Input/Output Settings window, choose the following settings,
»a. Set the desired EDID handshake that will be provided to the VGA source (fig. 1c)
»Note: Use the EDID rotary on the face of the unit to choose the desired handshake that will be
provided to the connected HDMI source.
»b. Set the desired output video resolution, aspect ratio, and picture mode that will be applied to the
VGA source (fig. 1d)

9
5. Use the Video Settings window to apply color and sizing adjustments to the VGA source (fig. 2a).
Press the Apply button to apply settings.
6. 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.
7. Your unit is now ready to control from the KDMS™Control Panel, KD-App, or by professional
control system.
