PRODUCT DESCRIPTION
DFU (Data Forward Unit) RHF3M485 is a transparent transmission device from high isolation RS485 and RS232 to LoRaWAN protocol. The DFU RHF3M485 includes a high isolation RS485 transceiver which make it could be used in complex industrial environment. A LoRa radio is integrated which support global LoRaWAN protocol, like CN470, EU433, EU868, US915, AS923, AU915, KR920 and so on. Furthermore, with its automatic packet segment function, automatic packet assembly function and packet buffer function, customer could insert this device and deploy it in the already existed system easily and quickly. This will help customer to update the traditional wired system to the smart wireless LoRaWAN system.
