Abstract
Abstract A transmitter-receiver controller system for remote actuation of devices or appliances such as security systems and garage door opener systems. The transmitter and receiver each utilize a programmable microcontroller for encoding and decoding signals. The device code, the data transmission format and the transmission frequency are selectable. The device code, data transmission format and the transmission frequency of the transmitter and/or the receiver can be selected to emulate other remote transmitter-receiver controller systems to enable operation of the present transmitter and receiver with those systems.
