Self-built server
If you have your own servers
ZHC2921 can communicate directly with the client server after simply configured. The ZHC2921 follows the Modbus RTU/TCP protocol and also supports 485-channel transparent transmission protocols.

If you don't have a Cloud Server
When some customers use the configuration software, they can't directly connect the PC and S485. The ZHC2921 supports the ZH-Cloud transmission. The customer only need to install the virtual serial port, the data of the ZHC2921 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)

Configuration software docking

ZHC2921 has an RS485 interface, which supports the standard modbus RTU/TCP protocol. The
configuration software can directly read and command the ZHC2921 through the RS485 interface.

Analog auto-calibration threshold reporting.
The ZHC2921 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.
