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
