Connections
Before making any connections, power off your source and display devices.
Tx Unit:
›Using a short HDMI cable, connect your source device to the HDMI port labeled “HDMI Input”.
For DVI-D/DVI-I sources, use appropriate adapters. For Display Port, use active converters.
›Connect the CAT5e/6 UTP or STP cable that connects to the Rx Unit at the port labeled
“CAT5e/6 Output”. Use 568-B Termination.
›Make IR In and Out connections to receive (IR In port) or send (IR Out port) control signals.
Refer to the “Extending IR & RS-232 Control” for more information.
›Connect a stripped wire to DB9 adapter cable for bi-directional RS-232 control.
Refer to the “Extending IR or RS-232 Control” and the “RS-232 Commands” section for more
information.
Rx Unit:
›Using a short HDMI cable, connect your output / display device to the HDMI port labeled
“HDMI Output”.

5
›Connect the CAT5e/6 cable at the port labeled “CAT5e/6 Input”. Use 568-B Termination.
›If you are sending or receiving IR, connect included IR Sensor and/or IR Emitter.
›If you are transmitting or receiving RS-232, connect to the IR out (RS-232) port.
›After all the connections are made, connect power using the included power supply and then
power up your source and display equipment.
Extending IR or RS-232 Control
RS-232:
Bi-directional RS-232 is achieved utilizing the IR Out (RS-232) port on the Tx and Rx units. The
connector is 3-pin phoenix and the pinout is the same on the Tx and Rx unit. RS-232 can not be used
at the same time as IR.
›RS-232 Pass-through Mode
»Send and receive (bi-directional) RS-232 commands for controlling remote equipment. Supports
baud rate up to 115,200bps.
›Control Mode
»Provides control of Tx units as well as connectivity status
»See RS-232 Commands section for more information
›Firmware Upgrade Mode
»Two different types of firmware may be updated: MCU (KD-X222PO units), and HDBaseT
(extension over CAT5e/6)
RS-232 Cabling
RS-232 cables are available through Key Digital and other wire suppliers, and can also be fabricated by
skilled technicians.

»“IR In” port on the Tx unit extends to the “IR Out” port of the Rx unit
»“IR In” port on the Rx unit extends to the “IR Out” port of the Tx unit
›IR In:
The IR In port is different for the Tx and Rx units. The Tx unit’s IR In port supports a Serial IR
(hardwired) connection. The Rx unit’s IR In port supports an IR Sensor.
»Tx Unit / Serial IR:
»A fixed 5V input signal on 2 phoenix pins
»Signal and ground are required
»Typically fed from a dedicated control system or an IR distribution block

Settings
EDID Control
EDID authentication is provided from the KD-X222/ KD-X222PO Tx unit to the connected input / source
device. The EDID file (AKA “handshake”) is selected using the EDID Control rotary on the Tx unit and
provides a list of compatible video and audio formats as well as digital data, informing the source device
what it should output. Most sources will comply with a new EDID file without a power-cycle, but each
source may behave differently.

Forced Hot Plug Detection (HPD)
Hot Plug Detection (HPD) may be forced on the Tx Rx unit in order to provide connected devices with
necessary voltage to inform the device that a partner (display) is connected and active. If the Control
rotary is set to any HPD Bypass setting, HPD signals from the output to the input device will pass as
normal. In cases of many layers of connectivity, HPD may be lost leading to no signal at the display. In
those cases, fix the Control rotary to any Forced HPD setting.
Range and Resolution:
Distance performance is significantly increased when using CAT6A Cabling.
»Up to 150 ft. @ 4K 24/25/30(4:4:4)/60(4:2:0) using CAT6A cabling
»Up to 125 ft. @ 4K 24/25/30(4:4:4)/60(4:2:0) using CAT5e/6 UTP/STP cabling
