IOTRouter 11 Factory made strictly checked gsm modbus rtu data logger

Self-built server

If Customers have their own servers, and the ZHC4931 can communicate directly with the client server after simply configured. The ZHC4931 follows the Modbus RTU/TCP protocol and also supports 485-channel transparent transmission protocols.

Configuration software docking

ZHC4931 has an RS485 interface, which supports the standard modbus RTU/TCP protocol. The configuration software can directly read and command the ZHC4931 through the RS485 interface.

If customer does not have a cloud server


When some customers use the configuration software, they can't directly connect the PC and S485. The ZHC4931 supports the ZH-Cloud transmission. The customer only need to install the virtual serial port, the data of the ZHC4931 can be forwarded to the local serial port of the PC, which is more convenient and quick.


(Also applicable to scenarios without a cloud server)

Analog auto-calibration threshold reporting

The ZHC4931 presets the analog linear calibration parameter value, the user only needs to modify the k/b value to achieve the linear calibration effect. In addition, the effect of analyzing the analog data can be realized by adjusting the k/b value, and the threshold will be reported.
