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.
Application of Serial to Ethernet Modem ZHC1661
Industrial Automation
Suitable for industrial automation production lines and can monitor
industry chain data in real time. Count the number of products by
pulse counting.
Traffic Lights Management System
Unified management of street lamps to achieve remote monitoring and
intelligent management of lighting. Reduce manpower management
costs and improve maintenance efficiency.
