Introduction
Key Digital®KD-Pro8x8D is a UHD/4K, HDCP 2.2, and ARC supporting digital video matrix
with audio de-embedding on analog and digital audio connectors. Video outputs feature
simultaneously active HDMI and HDBaseT ports for simplistic single-wire integration with
displays throughout the distributed video system. Six short range (model KD-X88SHRx)
and two long range extenders (model KD-X88LGRx) deliver UHD/4K video up to 125 ft. and
300 ft. respectively and are powered at the matrix switch. IR and RS-232 control routing
adds up to 34 control ports to third-party control systems.

Quick Setup Guide
1. Begin with the KD-Pro8x8D and all input/output devices turned off and power cables removed
2. Connect HDMI sources to the desired input ports on the KD-Pro8x8D
3. Connect HDBaseT outputs to the Rx extenders via CAT5e/6 cables
4. Connect HDMI output of Rx extenders to the output devices (display, projector, AV Receiver,
etc)
5. Connect HDMI outputs to the appropriate output device (output signals mirror HDBaseT
outputs)
6. Connect both power supplies (one for matrix and one for the POH Rx extenders) to the KD-
Pro8x8D and all other input and output devices and power them on
7. Operate the KD-Pro8x8D switcher via front panel buttons, IR Remote, Serial IR or RS-232
control. See Setting and Adjustments via Remote section for quick adjustments during initial
installation
8. If TCP/IP control is desired, set the IP address using appropriate Key Digital software from
www.keydigital.com. Note that many advanced commands are available only via TCP/IP and
RS-232 protocol
Settings and Adjustments via Remote
Many initial installation steps may be configured using the factory remote control. Other advanced
settings may be configured using USB and software downloaded from www.keydigital.com
Matrix Switching Command via IR
IR Button Sequence = Video Mode, X, Y
»X = Output # [1-8]
»Y = Input # [1-8]
EDID Handshaking Control
EDID (Extended Display Identification Data) is a data structure provided by a digital display to
describe its capabilities to a video source. This data is also known as a “handshake” and typically
includes manufacturer, serial number, product type, resolutions supported by the display, display
size, pixel mapping data, etc.
Key Digital EDID Control allows the integrator to choose the handshake that will be provided to
each HDMI source. The integrator may select from the following EDID file options:
»Default EDID Library: The EDID handshake is relayed to the source from the matrix
switcher’s default EDID table (see table below)
»Copy from connected HDMI or CAT5e/6 (HDBaseT) output: The EDID file of a selected
output device is copied to the software of the matrix switcher and relayed to the source.
This is sometimes necessary if working with very new or very old displays.
›EDID Setup Command via IR
»XX = Input # [01-08]
»YY = Output # [01-08]
»ZZ = Default EDID Table File [01-15]
