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.

 

 

Wiring Method


Connect the computer network port and the device's network port with an Ethernet network cable. After the device is powered on, observe that the WORK indicator should flash for 3 seconds, indicating that the network hardware environment of the device is normal and the Ethernet data interaction can be carried out.
The default IP address of ZHC1921 is 192.168.1.254. When configuring the device, you need to set the IP of the computer and ZHC1921 to the same IP address range, otherwise the device and the computer cannot communicate. After setting the parameters of the ZHC1921, connect the network port of the network device (router/switch/other) with the network port of the ZHC1921 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.

 

 

  • Function​ of ZHC1921

 

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.
