This electronic infrared adapter serial transceiver circuit is based on a TFDS4500 IC and can be used to transmit data from portable devices to a PC using IR and serial port .
Infrared Adapter Serial Transceiver Schematic
TFD4500 infrared adapter it’s a low–power infrared transceiver modules for serial infrared (SIR) data communication which support IrDA speeds up to 115.2 kbit/s. In this infrared circuit transceiver it’s integrated an photo diode infrared emitter (IRED) and a low–power analog control IC.
