Modbus TCP And MQTT Serial To Ethernet Modem For Industrial Automation

Parameters of Serial to Ethernet RTU ZHC1931

Introduction​ of Serial to Ethernet RTU ZHC1931

ZHC1931 is a network IO product that supports 2 dry (wet) node detection, 1 relay (COM, NO) output, 1 analog (current 4-20mA) detection, and 2 serial port transparent transmission. It is compatible with Modbus RTU/ TCP protocol.
With "remote control" as the functional core, it is highly easy to use. Users can easily and quickly integrate into their own systems to realize remote and local control based on Ethernet and RS485/RS232.

• Wiring of Serial to Ethernet RTU ZHC1931

Connect the device to the computer with a network cable. After the device is powered on, observe that the WORK indicator is always on, which indicates that the network hardware environment of the device is normal and can communicate with the device. After setting the parameters of the ZHC1931, connect the network port of the network device (router/switch/other) with the network port of the ZHC1931 with an Ethernet cable. After the device is powered on, observe that the WORK indicator should flash for 3 seconds, indicating the network hardware where the device is located The environment is normal, and Ethernet data exchange is possible.
