Universeller Fernsteuerungs-Sender mit vereinfachter Apparatidentifizierung.
摘要
A permanent non-erasable memory (16) stores formatting data and command bit patterns for a plurality of devices of different categories manufactured by different manufacturers to be controlled by the remote control transmitter incorporating the memory. To select the correct format, the user activates an enter initiate key, thereafter a key to indicate the category of the selected device, and thereafter two digits which together signify the manufacturer and model number. The keyboard output signals resulting from activation of tne keys are stored in RAM (44) in the microprocessor (10) controlling the remote control transmitter's operation. The stored values in RAM constitute an address for the memory. Under microprocessor control, the data read out from memory is then applied to the transmitter driver circuit (29) to cause the properly formatted device control signal to be transmitted.
