PIN 1 2 3 4 5 6 7 8 I/O I - - O I I I I FUNCTIONAL DESCRIPTION When data pin (K0~K3) set to “1”, RT1527 will transmit serial data waveform from C0~C19 to D0~D3 by radio frequency (RF) modulation. control application. This can be use in most of the remote Data Transmission Code Frame A code frame period is depended on data pin active period. the code word transmit continuously until data pin inactive. When data pin is active Format is as follow: A030324-V1.0 Encoder Rato CODE Word Code word consists of full set of serial data format. The bination is as follow: Sync. 20 Address Bits (C0~C19) 4 Data Bits (D0~D3) The Each code word consists of 20 address bits, 4 data bits and a synchronous bit. .. transmission sequence is as the diagram shown: D1 D2 D3 Sync C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 C14 C15 C16 C17 C18 C19 D0 CODE BIT Code bit is the bination of address and data bits, RT1527 transmit a serial of waveform is consist of code bits and sync. Logic low (“0”) and Logic high (“1”). oscillation pulse. Code bit...
