3. Product Overview
3.3.10. IR Connector
IR detector and IR emitter can be connected to the receiver with TRS (Tip, Ring, and Sleeve) connectors.
They are also known as (3,5 mm or approx. 1/8") audio jack, phone jack, phone plug, and mini-jack
plug. The pin assignments are the following for the detector and the emitter:
1 2 3
Detector – 3-pole-TRS
1 Tip IR Input -
2 Ring GND
3 Sleeve IR Input +
INFO: Ring pole of the emitter is optional. If your IR emitter has three pole-TRS plug, then the Ring and the
Sleeve are the same signal (Output - ).
You can find more information about Infrared interface in the
3.3.11. GPIO - General Purpose Input/Output Ports
