- Features of IOT Cellular Modem
- 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.
- When some customers use the configuration software, they can't
directly connect the PC and S485. 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)
