Suppliers of OEM 3G 4G rs485 RTU Module 4 20mA IOT Solutions Wireless Transceiver DTU for Alarm Oil Level System IOT Router

Configuration Software
The configuration software interface window is visualized, can ensure users to perform on-site or remote connection, debugging, configuration settings.

Device Transparent Transmission Network (Digital Radio)

The ZHC4012 supports networking functions and supports one-to-one and multiple-to-one networks. This need is very practical for some specialization scenarios.

Support automatic acquisition, active reporting, can dynamically modify collection instructions, collection cycle. Reduce server processing.

Support automatic identification of Modbus RTU/TCP protocol
Adaptive Modbus RTU/TCP protocol, the data format replied by the ZHC4012 is consistent with the data format sent by the cloud. 

Support heartbeat package, custom registration Settings and remote selection of registration package mode.

TCP CLient communication

The serial server initiates a TCP connection to the server actively. If the connection fails, the connection is repeated
repeatedly until it succeeds. If the connection is completed, the server and serial device can carry out two-way transparent data
transmission.

HTTP CLient communication

Support serial port data to be transmitted to the specified server by HTTP

Self-Built Server

If Customers have their own servers, and the ZMC4012 can communicate directly with the client server after simply configured. The ZHC4012 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. The ZHC4012 supports the ZH-Cloud transmission. The customer only need to install the virtual serial port, the data of the ZHC4012 can be forwarded to the local serial port of the PC, which is more convenient and quick. Also applicable to scenarios without a cloud.
