» 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 Ring.
IR In Tip Ring
Serial IR (Tx) IR In N/C
IR Sensor (Rx) IR In 5V
IR out:
➔
» Pass-through from signal of corresponding IR In port, as determined by the
position of the Control Rotary
» Driving power: 5V with 32mA minimum current
» Typically connected with an IR emitter
IR Out Tip Ring
Serial IR IR Out N/C
IR Cabling
Your KD-X611ProK 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-X611ProK. Third-party IR
Sensors may not work with KD-X611ProK.
The included IR Sensor.
The 3.5mm connector is stereo and it connects to
the IR In port of the Rx unit.

The included blinking-type IR Emitter.
The 3.5mm connector is mono and it connects to
the IR Out port of the Tx or Rx unit.
The sleeve of the 3.5mm Male connector must have good physical contact
with 3.5 mm Female input/output on the KD-X611ProK.
Some 3.5mm Male plugs feature a plastic
sleeve that extends longer than an average
sleeve. This may cause poor grounding
contact. See the example on the left.
