1.Introduction
1.1.
Brief Introduction
E62-DTU (433D20) is a full duple x wire less data transmission module for point-to-point transmission( Has both
RS232 and RS485), transmission power is 100mW, transparent transmission mode, working in 433MHz band.
Module has the function of frequency hopping spread spectrum (FHSS), in the p rocess of digita l transceiver module
both sides according to the frequency hopping algorithm automat ically synchronous jump in as many as 50 frequency
points (user customizable FM and sequence number), and greatly imp rove the anti-interference o f the module, the 433 m
frequency hopping technology in a leading position in the industry module with time fu ll duple x (TDD) features, at the
same time of receiv ing data, can send data, without waiting for rece iving co mplete in some a ir rate and serial port baud
rate can be realized under the co mbination of full duple x seria l t ransmission
。
For e xa mple : under the a ir rate of 64 k, the
serial port baud rate can be realized under 9600 BSP and fu ll-duple x data transmission in a row, in this case, there is no
limit to send and receive the packet size, module can keep low latency/high response at the same t ime , to ensure that the
data is transmitted to the other party as soon as possible.
E62-DTU (433D20) strictly ab ides by domestic and foreign design specificat ions such as FCC, CE and CCC, and
meets various radio-frequency related certifications and export requirements.
