FUNCTIONAL DESCRIPTION
1. TRANSMISSION CODE
The transmission code consists of a leader code, 16-bits custom codes, and 8-bits data codes. The b1s
complement code of the data code is also sent simultaneously. The following diagram shows this one frame
construction.
The leader codes consist of a 9ms carrier waveform followed by a 4.5ms OFF waveform. It is used as the
leader for the following code. Thus, when reception is configured by a microcomputer, the time relationship
