Description
Overview
GAOTek long range wireless transceiver module gateway transmitter receiver modbus transmitter receiver data transmission module, is designed and manufactured based on LLCC68 LoRa RF chip from Semtech. The master module can relate to the gateway via the RS485 port. The slave module can relate to the sensors or metes via the RS485 port, and it can also work as an end node and repeater simultaneously. The work mode can be set through the configuration tool.
Features
● Working frequency:430.5 to 509.5 MHz
● Isolated RS485 interface, Modbus RTU protocol
● Long distance point to point transparent data transmission
● Self-organizing network: self-routing and self-recovery, anti-interference
● Supports peer-to-peer communication between nodes and extends node reachability through multi-hop communication.
● low-cost, flexible, and easy-to-configure “out-of-Internet “communication
