They are used to verify the proper transmission. The code consists of two data bits (sufficient to encode 4 buttons) and two check bits. The pulse (burst) length is always 512 CPU cycles and is formed by a 16 impulses of carrier frequency. Individual samples are separated by an ultralong space (8192 CPU cycles). Long gap (2048 CPU cycles) between pulses is log1, short gap (512 cycles) is log0. The lower power consumption of transmitter. It has an advantage over pulse width coding (PWC) in Signals are transmitted by pulse distance coding, PDC. If you need to output to remain active only as long as the button is held, this is what you seek:Ĭarrier frequency if the remote control is from 36 to 38 kHz. The remote control operates on the infrared principle, with a range of up to 50m. Pressing buttons 1, 2, 3 or 4 turns the corresponding output on, pressing it again turns it off. This device is good for switching on and off up to 4 independent appliances by remote control.
