IR In:
• Connect the included IR sensor to collect line-of-sight IR from your device’s remotes
• Pinout: Tip = IR in/out signal, Ring = +5V sensor power, Sleeve = Ground
• By default, this port is not active. You must set the respective IR In/Out port on KD-MLV4x4Pro to IR
Output for this port to work.
• Only the provided IR Sensor should be used. Third-party sensors may not be compatible and/or may
result in damage
• The included IR Sensor Receives signals from a 90° angle at up to 30 ft. away.
• Maximum supported IR burst frequency is 55kHz.
LEDs
Power (Blue)
• Solid illumination during power on state, as
provided by healthy connection with power
supply and healthy PoC extension.
• Steady blink if unit has a power short
Link (Blue)
• Solid illumination from healthy UHDoTP link
between Tx and Rx units
Video (Red)
• Illumination with active TMDS (video +
audio) signal
• Off with no TMDS (video + audio) signal
Live (Amber)

HDMI Link (Blue)
• Solid illumination from active Hot Plug
Detection voltage with connected
display/output device
Forced HPD Slide Switch: In cases of many layers of connectivity or non-standard devices in-line, hot plug
detection (HPD) may be lost or drop below standard levels, leading to the video display not detecting a
connected source and resulting in no image.
• If set to ON, Hot Plug Detection (HPD) voltage is forced at the HDMI connection of the Rx unit. The
connected display will be fed a constant voltage to inform the device that a partner is always connected
and active.
• If set to OFF, Hot Plug Detection (HPD) voltage is passed thru from connected source to the display
FW (firmware) USB:
• Micro USB port
• Used for firmware updates (consult with Key Digital tech support before updating firmware)
o Note: After updating firmware, all unit settings are restored to defaults except IP information.
Please collect all customized settings info before loading firmware.
