Static (fixed-code) 433.92 MHz OOK/AM Manchester remote from the Telcoma /
Cardin EDGE family (EDGE2 / EDGE4 / EDGE20; sold compatible with TANGO /
QUASAR / SLIM / SE). Frame = 0xFF preamble + per-remote serial + a one-hot
channel marker; decoded to a canonical 32-bit key where key[31:24]=0xFF,
key[23:3]=serial, key[2:0]=one-hot channel (gate=0, others 1/2/4). The
channel-aware encoder reproduces each channel's exact waveform (gate channel
verified against the original remote's RF; gate frame is 32 data bits + a
required HIGH stop half-bit, other channels are 33 bits with no stop).
This is the EDGE 433.92 fixed-code protocol; it is NOT the existing Cardin
S449 (FSK KeeLoq rolling) or S466 (27 MHz PWM), which are different products.
