Industrial Grade Multiple Function 4G DTU
RS485/232 bidirectional transparent transmission
High-performance industrial-grade 32 bit communication processor
Low latency,High speed,High stability
Basic Function
User device data is transmitted to 4G DTU via RS485/232, then DTU transmit data to server via transparent transmission,and DTU support GPRS/4G phone card or IoT card, which can be widely used in the sensors,PLC,serial device,collector.
Fast server development
Support TCP_ZSD/UDP_ZSD/TCP_Client/UDP_Master/HTTP/MQTT, provide free configuration software,config server domain name or IP, quickly establish communication with server.
Three-way SOCKET supported
support three-way center path and three-way center data monitoring under TCP_Client/UDP_Master mode
Multiple SCADA supported
Support mainstream SCADA, like kingview/Wellin/ForceCon,PLC can be connected to SCADA via RS485/232
Modbus Gateway
Support Modbus RTU to Modbus TCP,support Modbus polling,DTU can actively collect Modbus devices
SMS transparent transmission
When the network is interrupted or no signal, you can turn on the cloud switch and reset the DTU through the SMS transparent transmission technology, and support sending SMS alarm to multiple phones.
Registration packet&Heartbeat packet&Header packet
support Registration packet/Heartbeat packet/Header packet under TCP_Client/UDP_Master protocol
Heartbeat packet support serial port; network heartbeat,Registration support IMEI,ICCID,custom registration;Header packet support custom identifier.
Remote parameter change/upgrade
With the remote management platform, it can realize remote modification of parameters and remote upgrade of firmware to ensure long-term stable and reliable operation and save traffic and time.
