Key Data Code

Refer to the above diagram, the transmission code consists of leader code, customer code, and key data code.; The

leader code consists of a 4.5 ms carrier waveform followed by a 4.5 ms OFF waveform. The 8-bits customer code

transmitted two times; The 8-bits key data code transmitted two times also, first is the origin code; second is the

inverse code.

The code uses the PPM (Pulse Position Modulation ) Method, with “0”and “1” differentiated by the time between

pulses.
