Introduction

Key Digital® KD-Pro2x1X/KD-Pro4x1X are 4K/18G HDMI switchers with analog and digital audio
de-embedding, auto switching, and app-ready controllability. Designed for professional audio video
installations in conference rooms, huddle spaces, classrooms, theater and gaming spaces, KD-Pro2x1X/
KD-Pro4x1X enables multiple video sources to connect to a single video display while analog (3.5mm &
balanced/unbalanced) and digital (optical & PCM) audio de-embed ports may feed audio of the selected
source into and amplifier, DSP, or sound bar. Integrating KD-Pro2x1X/KD-Pro4x1X with KD-Amp220
will enable an app-ready all-in-one solution for control of video switching with sound and speech
enforcement. KD-Pro2x1X/KD-Pro4x1X HDMI switchers support 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-Pro2x1X/KD-Pro4x1X can also be controlled via trigger voltage and
features status-monitoring LEDs.

CAT cables removed

2. Connect your HDMI sources to the input ports of KD-Pro2x1X/KD-Pro4x1X unit

3. Connect your HDMI display to the output port of KD-Pro2x1X/KD-Pro4x1X unit

4. Connect analog and/or digital audio outputs to amplifier, DSP, AV receiver, or sound bar

5. Connect control system and/or PC to TCP/IP, RS-232, Serial IR port or IR sensor

6. Screw-in the power supply to the KD-Pro2x1X/KD-Pro4x1X unit, then, plug-in to power outlet

7. Power on input and output devices

Option 3: Control via professional control system

KD-Pro2x1X/KD-Pro4x1X allows control over serial interface for bi-directional communication.

Pin: 1 2 3 4 5 6

› For RS-232 control use pins 4, 5, and 6 of the Main Control port

Connection Protocol:

» Baud Rate = 57,600 bits per second
» Data Bits = 8
» Stop Bits = 1
» Parity = Non
» Flow Control = None
» Carriage Return: Required at end of string

› 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 switches have supported a standard HDMI switching

command. KD-Pro2x1X/KD-Pro4x1X 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.
