Parameters of ZHC1921
Introduction of ZHC1921
ZHC1921 is a network IO product that supports 6-way dry (wet) node detection, 4-way relay (COM, NO) output, 4-way analog (current 4~20mA) detection, and 1-way serial port transparent transmission, compatible with Modbus RTU/TCP protocol. With "remote control" as the core of the function, it is highly easy to use, and users can easily and quickly integrate into their own systems to achieve remote based on Ethernet and RS485 with Local control.
The default IP address of ZHC1921 is 192.168.0.65. The configuration requires that the computer and ZHC1921 IP be set to the same IP address segment, otherwise the device and the computer cannot communicate.
ZHC1921 has built-in parameter configuration webpage. Users who use this device do not need to pay attention to the relevant holding registers of the device. They only need to understand the reported data of the device.
Set up ZHC1921 then use the Ethernet cable to connect the network port of the network device (router/switch/other) with ZHC1921. After the device is powered on, observe that the WORK indicator should flash for 3s, indicating that the network hardware environment where the device is located is normal and Ethernet data can be exchanged.
