Rx Unit:
➔Using a short HDMI cable, connect your output / display device to the HDMI port
labeled “HDMI Output”.
➔Connect the CAT5e/6 cable at the port labeled “CAT5e/6 Input”.
➔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 to the Tx and Rx
(KD-X222 only) using the included power supplies and then power up
your source and display equipment.
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”.
➔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”

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-X222/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 Cabling
Your KD-X222/X222PO includes an IR Sensor and an IR Emitter.
Signal acceptance:
The IR Sensor receives signals from a 90° angle at up to 30 ft.
away. It accepts a maximum IR burst frequency of 55kHz.
Only the included IR sensors are compatible with the KD-X222/ KD-X222PO.
Third-party IR Sensors may not be compatible.

Connects to the IR In port on.
The included blinking-type IR Emitter.
Connects to the IR Out port.
IR
Bi-directional IR control extension is supported. IR can not be used at the same
time as RS-232.
»“IR In” port on the Tx unit extends to the “IR Out” port of the Rx unit
»IR signal, ground, and 5V power are required
➔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
»
Rx Unit / IR Sensor:
»IR Sensors can be connected directly into the Rx unit’s IR In port, without
the need for an external IR distribution block
»IR signal on the Tip, with 5V powering of the IR sensor on the power wire.

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.

»Color: Green
»Solid illumination during power on state, as provided by healthy connection

»Steady blink if power is not adequate and/or if there is a connectivity problem
with the KD-X222PO Rx unit
HDMI Link (HDMI Input/Output):
»Color: Blue
»Tx Unit: Solid illumination from active signal (HDMI TMDS) reception from
connected source device
»Rx Unit: Solid illumination from active Hot Plug Detection voltage with
connected display/output device
»If Hot Plug Detection is forced to input device from Tx unit, the HDMI Active
light will illuminate solid regardless of HDMI signal from connected device.
CAT5e/6 Input/Output Link:
»Color: Blue
»Tx Unit: Solid illumination from active link and Hot Plug Detection voltage
from Rx unit
»Rx Unit: Solid illumination from active link with Tx unit
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.
