Parameters of Serial to Ethernet Modem ZHC1661

Introduction​ of Serial to Ethernet Modem ZHC1661

ZHC1661 is a network IO product that supports 4 channels of analog detection (current 4~20mA), 2 channels of analog output (4~20mA), and 1 serial port (RS485) transparent transmission. It is compatible with Modbus RTU/TCP protocol. With "remote control" as the functional core, it is highly easy to use, and users can easily and quickly integrate into their own systems to realize remote and local control based on Ethernet and RS485.

• Simple Use of Ethernet Modem ZHC1661

The default IP address of ZHC1661 is 192.168.0.65. During configuration, the IP of the computer and ZHC1661 must be set to the same IP address range, otherwise the device and the computer cannot communicate. ZHC1661 has a built-in parameter configuration webpage, users do not need to pay attention to device related holding registers, only need to understand the reported data of the device.
After setting the ZHC1661 parameters, connect the ZHC1661 to the network with a 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 data interaction is possible.
