The transmitting/receiving part of this device uses T966/T988 multiway wireless transceiver module. The transmitting part adopts T966 2-key type emitter, and the receiving part work principle is shown in the figure. Turn on the power supply, IC2 is restored, Q1 and Q2 output low level, T1 and T2 cut-off, J1 and J2 are not absorbed, motor M stops, the curtain jibs. When press remote control transmitting key C, C end of IC0 outputs high level, D1 cuts-off, I0 end outputs high level, then the high level shape is changed through IC1-1, IC1-2 and is sent to CP1 end of IC2-1.
