RF wireless module must use signal modulation to work properly. Common fixed code encoding devices such as PT2262/2272 can be connected directly. It is very simple, because it is a special encoding chip, so the effect is very good and the transmission distance is very long. RF receiver
RXB8 module is also important for data communication with single chip microcomputer. At this time, there are certain skills. Reasonable communication rate, the maximum data transmission rate of the data module is 9.6kbs, generally controlled at about 2.5K, too high data rate will reduce
RXB8 receiving sensitivity and increase the bit error rate or even cannot work at all. Reasonable information code format, microcontroller and RF module work, usually define their own transmission protocol, no matter what modulation mode is used, the information code format to be transmitted is very important, it will directly affect the reliable data transceiver.
