Transmission is enabled by providing ground to pin14 which is active low. The \u003cstrong\u003eControl Signals\u003c\/strong\u003e are given at pins 10-13 of HT12E. The serial data is fed to the RF transmitter through pin17 of HT12E. The transmitter, upon receiving serial data from encoder IC (HT12E), transmits it wirelessly to the RF receiver. The receiver, upon receiving these signals, sends them to the decoder IC (HT12D) through pin2. The serial data is received at the data pin (DIN, pin14) of HT12D. The decoder then retrieves the original parallel format from the received serial data.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eA signal is sent by lowering any or all the pins 10-13 of HT12E and the corresponding signal is received at the receiver’s end (at HT12D).
