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.

Claims

1. In a transmitter-receiver system in which a transmitter transmits at least one coded signal to a receiver, said transmitter comprising:

a first circuit to provide a first value consisting of an address;

a second circuit to provide a second value selected from a plurality of values, each of which is representative of a different data transmission format; and

a third circuit coupled to said first circuit and to said second circuit, said third circuit generates a coded signal that includes said first value, in a data transmission format selected by said second value.

2. The transmitter of claim 1, wherein said first circuit includes a plurality of switches located within a dual-inline package switch.

3. The transmitter of claim 1, wherein said first circuit includes a plurality of switches that are selectable to provide said address.

4. The transmitter of claim 1, wherein said second circuit comprises at least two input terminals that provide a first output signal representative of a first data transmission format when closed, and provide a second output signal representative of a second data transmission format when open.

5. The transmitter of claim 4, wherein the at least two input terminals of said second circuit are coupled by a jumper.

6. The transmitter of claim 1, further comprising a fourth circuit coupled to said third circuit, said fourth circuit being configured to provide one of a plurality of transmission frequencies, said fourth circuit transmits said coded signal at the selected transmission frequency.

7. The transmitter of claims 6, wherein said fourth circuit comprises:

an oscillator circuit that provides one of said plurality of transmission frequencies, said oscillator circuit having two input terminals that provide a first transmission frequency when closed and provide a second transmission frequency when open; and

an antenna for transmitting the coded signal at the selected transmission frequency.
