Parameters of Serial to Ethernet Modem ZHC1661

Introduction​ of Serial to Ethernet Modem ZHC1661

Product model: ZHC1661, the network is Ethernet, RS485/4AI/2AO interface is provided.
Special functions: AO remotely follows AI, 4-20mA analog quantity automatic report, 12-bit sampling accuracy.
Protocol: Support Modbusr RTU/TCP adaptive.
Industrial-grade quality: can work normally at -20℃~+60℃, galvanized steel plate material, dual watchdogs
Application: telecommunication equipment room monitoring, reservoir water level monitoring, boiler room temperature management monitoring, etc.

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.

AI voluntarily report description:

Disable reporting mode: Report all AI values cyclically according to the set cycle.
Report within the interval: When the set AI channel value enters the interval from outside the interval, all AI channel values are reported immediately and the cycle time is reset.
Report outside the interval: When the set AI channel value enters the interval from inside the interval, all AI channel values will be reported immediately and the cycle time will be reset.

• 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.
