- Overview：
- Cat4 mode：LTE-FDD、LTE-TDD、TD-CDMA、WCDMA、CDMA2000、CDMA、GPRS
- Cat1 mode：LTE-FDD、LTE-TDD、WCDMA、GPRS
- Provide 2 channels of analog input (resolution 12bit), support 4-20mA current and 0-5V voltage
- Support TCP / UDP, multiple socket protocols and multi server parallel communication
- Comway Protocol
- Standard TCP/UDP Protocol
- It provides a controllable power output. 24V / 12V can be selected by jumper, or the output is equal to the input voltage, which is convenient to control the sensor power supply in micro power consumption mode
- 485 port 1 is the Modbus master port and supports querying the 485 slave devices connected to it through Modbus RTU protocol
- Automatic online network timing, with clock error of second level
- Run in micro power consumption mode, sleep standby power consumption is 170ua@7.2v
- Upload message: in string format, it can be connected to dc-web cloud monitoring to display data on computer or mobile terminal
- Support mqtt, HTTP protocol and customized protocol to facilitate communication with multiple platforms
- Support device monitoring by Scada software through comway virtual serial software or VPN network on modbus rtu or tcp protocol
- Online network management is realized through Netview software
