Examples of Wiring to IR Receivers and Emitters
Kingbright APECVA3010P3BT Phototransistor
These are popular SMT phototransistors. The carrier frequency is filtered out, so run the IR data recording in the no-carrier mode (command register, bit 4 = 1). The output produced by this circuit is "normal" (non-inverted), so set bit 2 of the command register to 0.
This is a photodetector and preamplifier in one package, with good noise filtering. This part is fast enough to preserve the modulation frequency in the output signal. Therefore, set bit 4 of the command register to 0. The output produced by this IC is "normal" (non-inverted), so set bit 2 of the command register to 0.
This is a high-power infrared emitting diode, very popular for IR applications. Notice that a current-limiting resistor is not necessary. The diode connects directly to the VCC and IR OUTPUT lines of Tibbit #26.
Xantech 282D "Designer" Emitter and 283D Emitter
To connect this emitter, cut the audio connector off the emitter's cable, then connect the black-and-white wire to VCC and the black wire to IR OUTPUT.
