868MHz 915MHz LoRa Industrail Grade Wireless Data Transmission Staion E95-DTU(900SL22-485) 5KM 22dBm DC8～28V RS485 Modbus - CDBAIRUI, 0302010800000012

• Supports multiple protocols such as ModBus. with multi-level relay network function Simultaneous operation of multiple networks in the same area to achieve mutual forwarding from multiple LANs to the loT Fast and easy wireless data transmission-No network coverage required. No SIM card. Self-contained wireless transceiver. Ready to use right out of the box SX1268 chip solution Compared with the ordinary LoRa, the new generation of LoRa has longer communication distance. faster transmission rate low power consumption. automatic relay networking and LBT environment monitoring Support for LBT environment monitoring Active listening to the channel environment noise before transmission and delaying transmission when the noise exceeds the threshold value, improving the success rate of data transmission more effectively Multiple hardware protection features -Stable and reliable, with multiple hardware protection such as power pulse protection, reverse connection protection and antenna surge protection, effectively preventing human error and accidents in harsh Built-in watchdog and anti-crash design-Professional and accurate time layout. Once an abnormality occurs, the digital radio will automatically restart and will continue to work according to the previous parameter settings, No need to be on duty, stable operation Temperature compensated circuitry with frequency stability better than +1.5PPM.Ensure that the circuit works normally and stably within a certain temperature range, so that the device parameters remain the same or change as little as possible, the frequency deviation is small and the frequency is more accurate and stable Easy to switch between working and configuration modes by using the button.Press and release for 1 second to switch modes
