WKB-250 Work Basis (工作原理)

Keypad:

1. When user typing the keypad, membrane will detect the
user typing character, then send signal to the MCU.
2. The MCU will encode the signal and modulate the signal that
use FSK modulation type)
3. Through the 27 MHz RF circuit transmit the modulation
signal.

Receiver:

1. When the receiver receives the modulation signal will
demodulate signal through RF circuit. And then responds
signal to MCU.
2. The MCU meeting decodes the signal PC acceptable format.

ps. FSK: Frequency Shift Key
MCU: Micro Control Unit
RF: Radio Frequency
