CWT-L Series New Arrival Modbus Rs485 Gprs Gsm Rtu Dtu Modem
CWT-L Series New Arrival Modbus Rs485 Gprs Gsm 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
