Waveshare Rail-mount SX1262 LoRa Data Transfer unit, RS232/RS485/RS422 to LoRa, Suitable for Sub-GHz band
Description:
SX1262-LoRa-DTU is a wireless data transfer unit with RS232, RS485 and RS422 interfaces based on the SX1262 module. Adopts LoRa Modulate and Demodulate technology, with the advantages of anti-interference and long-distance communication (up to 5KM). Supports point-to-point, point-to-multipoints, relay network, AES, etc. Compact size and easy to install, suitable for the wireless data transmission and device control of industrial standard or non-standard user protocol.
Primary Function
Support RS232 / RS485 / RS422 To LoRa
* Note: It does not support RS232, RS485, RS422 to LoRa at the same time, and RS232, RS485, RS422 cannot be converted to each other at the same DTU.
Industrial Rail-Mount Design, Small In Size, Easy To Install, And Cost-Effective
Compared to traditional communication, LoRa Chirp Spread Spectrum (CSS) and Frequency Hopping Spread Spectrum (FHSS) technologies greatly improve the performance of long-range communication and anti-interference, widely used in military and industrial communication fields.
Can Be Set Via Software
The Radio Station Can Realize Multi-Level Relay Networking, Suitable For Ultra Long-Range Distance Or Complex Environment Networking Communication, Allows Multi Networking On The Same Region
Users Can Query The Current Status Of The Module Or Set Parameters By Sending AT Commands
The Secret Key Is Writable But Unreadable, The Devices With The Encrypted Transmission Enabled And The Same Key Can Communicate With Each Other Normally For Greater Security
The module will actively monitor the environmental noise of the channel before sending. If the noise exceeds the threshold, the sending will be delayed. This function can improve the communication success rate of the module in harsh environments, suitable for networking transmission and anti-collision processing
Supports serial port output of data packet signal strength, can be used to evaluate signal quality, improve communication network, and measure distance. Supports serial port output of environmental noise signal strength, can be used to manually realize LBT function.
Features:
- Adopts LoRa Modulate and Demodulate technology, anti-interference and long-distance communication.
