Step 9: AFTER all connections are made, plug-in power supplies to power outlets
Step 10: Power on input/output devices

Installation and Operation

Before permanently securing the unit for final installation, test for proper operation of the unit and cables in your system. It is recommended that you leave enough ventilation space to provide sufficient airflow and cooling.

You MUST use the Power Supply PROVIDED with your unit or you VOID the Key Digital® Warranty and risk damage to your unit and associated equipment.

Application Example

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:

• 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

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 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

» 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.

IR Cabling
Your KD-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-X222PO. Third- party IR Sensors may not be compatible.

The included IR Sensor.
Connects to the IR In port on the Rx unit.

The included blinking-type IR Emitter.
Connects to the IR Out port.

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.

Control Rotary
The Control rotary enables the integrator to choose the desired setting for IR Out (RS-232) ports, RS-232 Mode, and Hot Plug Detection control.
The Control Rotary is located on the Tx unit.
> IMPORTANT! Please apply light pressure to the Control rotary when making your selection

Control Rotary Position Assignments:

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
» Up to 250 ft. @ 1080p / 1920×1200 using CAT6A cabling
» Up to 200 ft. @ 1080p / 1920×1200 using CAT5e/6 UTP/STP cabling

NOTE: Use shielded metal RJ45 connectors with soldered ground wires when terminating shielded CAT5e/6.
