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.
Claims6
In a transmitter-receiver system in which a transmitter transmits a coded signal to a receiver, the coded signal having a transmission format and is transmitted at a frequency, said transmitter comprising:
- a plurality of switches that are selectable to provide an address;
- a first circuit having a plurality of input terminals that are selected to provide one of a plurality of output signals, each of which is representative of a different data transmission format;
- a microcontroller coupled to said plurality of switches and said first circuit, said microcontroller generates a coded signal in the selected data transmission format, said coded signal including the selected address;
- and
- a second circuit coupled to said microcontroller, said second circuit having a plurality of input terminals that are selected to provide one of a plurality of transmission frequencies, said second circuit transmits said coded signal at the selected transmission frequency.
