CWT-L M2M Iot Modbus Rs485 Gsm Gprs 3g 4g Rtu Dtu Modem


 


Overview


For acquiring the remote operating parameters and process management, CWT-L series IOT M2M Gateway help machine to access internet via GPRS/4G/Wi-Fi and establish TCP/IP connection with server.


CWT-L can be widely used in industrial automatic control, base station / computer room monitoring, environmental monitoring, water conservancy project, power industries, agriculture, etc.



 


 


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
