Remote transmitter-receiver controller for multiple systems

Abstract

The present invention provides a transmitter-receiver system which may selectively operate at one of a plurality of transmission frequencies and may selectively encode/decode the transmitted data in one of a plurality of data transmission formats. The present invention also provides a transmitter-receiver system in which a signal is transmitted using at least two different formats, so that manual selection of a specific transmission format is not required. Each transmitter and receiver includes a microcontroller which has been programmed to implement multiple encoding/decoding schemes and multiple data transmission formats in the unit. The microcontrollers may be programmed to implement any desired encoding/decoding scheme including the capability of emulating the encoding/decoding schemes and data transmission formats of transmitter-receiver systems currently in common use. The encoding/decoding scheme, the data transmission format and the data transmission frequency of the units are easily selectable from preprogrammed alternatives via selected switch settings in the individual devices. The transmitter or receiver may then be used in conjunction with the corresponding transmitter and/or receiver having the selected operating parameters, including but not limited to ASIC-based systems.
