Introduction
1.1 Brief introduction
E32-DTU(433L33)-V8 is a wireless modem that adopts military-grade LoRa modulation technology. Due to its
advanced modulation method, the communication distance and stability are greatly improved. On the basis of the original
built-in power amplifier (PA) and low noise amplifier (LNA), the maximum transmit power reaches 2W and the
receiving sensitivity is also improved to a certain extent. Noise amplifier products have been greatly improved. The
difference is analog FM radio plus MODEM analog modem, which provides transparent RS232/RS485 interface,
working in 433MHz with communication distance up to 12km.
As a communication medium, it has a certain scope of application such as optical fiber, microwave and open wire: it
provides real-time and reliable data transmission of monitoring signals in private networks under certain special
conditions, with low cost, installation and maintenance. It features convenience, strong diffraction ability, flexible
network structure, and long coverage. It is suitable for occasions such as many and scattered points and complex
geographical environment. It can be connected with PLC, RTU, rain gauge, liquid level gauge and other data terminals.
