Connect to PLC or PC and achieve long-distance LoRa communication via RS232C.
In research fields, long-distance and stable data transmission is required for the collection of experimental and observational data. Particularly in measurements conducted outdoors or in remote locations, the need for wireless communication increases due to wiring constraints. The SLR-429M RS-232C interface board connects to PLCs or PCs with an RS232C interface, enabling long-distance data transmission via LoRa communication. This allows researchers to efficiently collect data without being restricted by location. 【Usage Scenarios】 - Data collection from sensors in remote locations - Data communication between devices within research facilities - Data logging in outdoor experiments 【Benefits of Implementation】 - Expansion of data collection range through long-distance communication - Integration with existing equipment via RS232C connection - Stable data transmission using LoRa
