Abstract
Transmitters and receivers for controlling remote elements which use a synchronous serial transmission format and which allows changes in coding to be automatically made between the receiver and transmitter and wherein the code is stored in memories of the transmitter and receiver and wherein the receiver can generate and transmit a new code with a light emitting diode so as to change the code in the transmitter. The transmitter and the receiver use micro-computers which are suitably programmed and include non-volatile memories.
