REMOTE CONTROL Barrier systems and garage doors need a receiver and transmitter to provide movement. Receiver cards are mounted inside barrier or sliding door motors. In some barrier and garage door systems, the receiver card is integrated into the barrier main control card. Transmitters are called remote controls. Transmitters can be multiple, depending on the type of receiver card and the type of controller, there are duplicate and non-copied remotes. Rolling skip controls are control models that cannot be copied. It is necessary to introduce this control to the receiving card one by one. In other transmitter controls, there is no need to introduce an encrypted control to the receiving card, and after encrypting the other controls with the same encryption method, there is no need to introduce it to the receiving card. It is carried out by encrypting with the switch method.
