Model: RX500 RX500 receiver module is receiving the UHF ASK demodulation equipment, support ASK demodulation. The receiver module has high sensitivity (-110dBm), low power consumption performance (<6mA), and a high dynamic range (greater than 60dB). The receiving module uses a highly integrated chip, built-in front-end low-noise amplifier, mixer, filter, frequency synthesizer and other circuits, which can optimize the signal to the greatest extent. Features RX500 receiver module has high sensitivity (-110dBm) and support ASK demodulation;Frequency: 315MHz(RX500-3) / 433.92MHz(RX500-4);Bandwidth 300KHz;Wide operating voltage range: 2.0V-5.0V;Low power consumption;Good selectivity and spurious radiation suppression, Can pass CE / FCC international certification easily;Good local oscillator...
Function description and setting method of KR2202 (remote switch controller/receiver):
A) Reset function:
After pressing the learning button of the KR2202 8 times, the KR2202 clears all remote control data in its memory.
