Basic Features
1. RS485 to GPRS/4G/Wi-Fi to server

Mode A: Two-way data transparent forward between RS485 and server

Not change the communication data format


Mode B: Modbus master mode on RS485

CWT M2M IoT Gateway(RTU) as modbus master read slave over RS232/RS485, then push slave data to server by TCP/IP(optional multiple protocol)



2. IO to GPRS/4G/Wi-Fi to server
