High Isolation RS485 interface RHF3M485 is a transparent transmission device from high isolation RS485 and RS232 to LoRaWAN transceivers. The device includes a high isolation RS485 transceiver which allows it to be used in complex industrial environments. A LoRaWAN transceiver is integrated and supports global LoRaWAN protocol, for example CN470, EU433, EU868, US915, AS923, AU915, KR920 and so on. With its automatic packet segment function, automatic packet assembly function and packet buffer function, customers can insert this device and deploy it in existing systems quickly and easily. This will help customers to update the traditional wired system to a smart wireless LoRaWAN system. The device can be used with industrial automatic equipment, industrial controls, smart meters, smart homes and etc.
