rc_encode

Name	RC Encode
Description	Remote Control Encode.
Status	supported
License	GPLv2+
Source code	decoders/rc_encode
Input	logic
Output	none
Probes	data
Optional probes	none
Options	remote;

The rc_encode protocol decoder can decode the remote control protocol which is frequently used within 433MHz key fobs and power socket remotes.

Decoder

They contain encoding chips like the Princeton Technology Corp PT2262 which converts the button pressed and address settings into a series of pulses which is then transmitted over whatever frequency and modulation that the designer chooses. These devices operate at a number of frequencies including 433MHz.

The decoder also contains some optional additional decoding for a Maplin L95AR remote control and will turn the received signal into which button was pressed and what the address code DIP switches are set to.
