Rail-mount SX1262 LoRa Data Transfer unit (Outputs RS232/RS485/RS422)

The SX1262-LoRa-DTU is a wireless unit for data transfer that supports RS232, RS485, and RS422 interfaces. Built on the SX1262 module, it uses LoRa technology to offer reliable long-distance communication up to 5 kilometers and resists interference. This unit can handle different communication setups like connecting directly between two points, linking multiple points, and using relay networks, with added encryption for security. Its small size makes it easy to install and ideal for managing wireless data transmission and device control, whether using standard or custom industry protocols.
