Description
Overview
GAOTek wireless global frequency LTE & LoRaWAN communication module with antenna is a new wireless data acquisition device. The uplink communication includes 2G, 4G, NB, LoRaWAN and other communication modes. The down link interface provides a standard RS 485 data interface, which can easily connect power meters and RTUs, PLC, industrial computers and other equipment, only need to complete the initial configuration, you can complete the data acquisition of MODBUS equipment. At the same time, wireless communication terminal uses a powerful micro processing chip, with built in watchdog technology, reliable performance stable.
Features
