RDI403


1.Introduction

1.1Description

RDIx03 is a DTU of RS485-LoRaWAN independently developed by ManThink Technology Co. Ltd with highly flexible configuration and low power consumption.  It is embedded with a high-performance MCU of NXP and a Radio chip SX127x of Semtech. It can get data from several slave devices by RS485  and uploading data to platform through LoRaWAN network.Users can quickly and flexibly configure DTU's working mode as needed,and quickly occupy the market.

1.2Applications

  • Industrial filed
  • Electricity  IOT
  • Hydrometeorological monitoring
  • Environment protection, municipal administration engneer and other related scene

1.3Features

  • RS-485 supports various baud rates and verification methods,filtering noise data and retry when communication of RS-485 is timeout.
  • Supports communication with devices  of different protocol types.
  • Support remote and field FUOTA upgrade
  • Support relay
  • Support multicast
  • Support precise timing
