1.Introduction
1.1.
Brief Introduction
E62-DTU (433D30) is a full duplex wireless 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 process of digital transceiver module
both sides according to the frequency hopping algorithm automatically synchronous jump in as many as 50 frequency
points (user customizable FM and sequence number), and greatly improve the anti-interference of the module, the 433 m
frequency hopping technology in a leading position in the industry module with time full duplex (TDD) features, at the
same time of receiving data, can send data, without waiting for receiving complete in some air rate and serial port baud
rate can be realized under the combination of full duplex serial transmission
。
For example: under the air rate of 64 k, the
serial port baud rate can be realized under 9600 BSP and full-duplex 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 time, to ensure that the
data is transmitted to the other party as soon as possible.
E62-DTU (433D30) strictly abides by domestic and foreign design specifications such as FCC, CE and CCC, and
meets various radio-frequency related certifications and export requirements.

Aluminum alloy case, compact size, great heat dispersion; good shielding, prime electromagnetic compatibility and
strong anti-interference.
★
Power reverse & overload protection and antenna surge protection functions significantly improve the reliability.
★
Parameters can be configured by programming, such as TX power, frequency point, air data rate, address and so on.
★
Ultra-low power consumption, standby current is only 40mA (even lower under power-saving and sleep modes), TX
current ≤0.3A .
★
Embedded watch-dog and precise time layout, modem will restart automatically upon abnormal situation and work
with previous parameters.
