Serial to Wireless Converter Gps DTU NB IOT Router ZHL4921G M2M Gsm Module M2M Gsm Ethernet IO Controller 4-20ma RTU

Self-built server
If you have your own servers
ZHL4921G can communicate directly with the client server after simply configured. The ZHL4921G 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 ZHL4921G supports the ZH-Cloud transmission. The customer only need to install the virtual serial port, the data of the ZHL4921G 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

ZHL4921G has an RS485 interface, which supports the standard modbus RTU/TCP protocol. The
configuration software can directly read and command the ZHL4921G through the RS485 interface.

The ZHL4921G supports networking functions and supports one-to-one and multiple-to-one networks. This need is very practical for some specialization scenarios.

Analog auto-calibration threshold reporting.
The ZHL4921G 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.

Product Applications
Serial to Wireless Converter Gps DTU NB IOT Router ZHL4921G M2M Gsm Module M2M Gsm Ethernet IO Controller 4-20ma RTU

DTU/RTU Modem is required in many places. Such as factory reservoirs, reservoirs for irrigation of farmland, water towers for water supply, water levels for rivers, etc. It is important to monitor the water level remotely. IOT Router Modbus RTU to TCP ZHL4921G Modebus IO Remote Terminal Unit DTU rs485 to MQTT Level Meter Data Logger has a built-in GPRS module that can receive the water level value returned by the water level detector and transmit the data to the monitoring center.
Complete the on-site data acquisition and upload function with the water level detector. Suitable for complex terrain and remote mountainous conditions, it can be used in pool water level monitoring, water tower water level monitoring, water tank water level monitoring, reservoir water level monitoring, river water level monitoring, natural gas storage tank liquid level monitoring, and oil storage tank liquid level monitoring.
