Rail-Mount SX1262 LoRa DTU
RS232 / RS485 / RS422 To LoRa
Suitable for data acquisition in industry and agriculture
Features At A GlanceSX1262-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
- Adopts LoRa Modulate and Demodulate technology, anti-interference and long-distance communication
- Adopts the original SX1262 chip, with -148dBm reception sensitivity and 22dBm emitt power
- Supports preamble detection, with CRC, automatic packetization, 960 bytes cache functions
- Supports LBT sending, RSSI output, AT command configuration
- AES communication to ensure data transmission security
- Supports multi-level relay networking to increase the wireless communication distance
- Supports host configuration and firmware upgrade (support firmware customization for batch order)
- Adopts high-quality components such as TCXO to ensure stable operation under harsh working conditions
- Comes with development resources and manual

Rail-Mount LoRa Data Transfer UnitIndustrial Rail-Mount Design, Small In Size, Easy To Install, And Cost-Effective
The LoRa Spread Spectrum TechnologyCompared 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.
Multiple Communication Methods
Can Be Set Via Software
Relay NetworkingThe 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
AT Command ModeUsers Can Query The Current Status Of The Module Or Set Parameters By Sending AT Commands
AES CommunicationThe 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
Listen Before Talk (LBT)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
Receive Signal Strength Indication (RSSI)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.
