Introduction of Serial to Ethernet RTU ZHC1931
ZHC1931 is a network IO product that supports 2 dry (wet) node
detection, 1 relay (COM, NO) output, 1 analog (current 4-20mA)
detection, and 2 serial port transparent transmission. It is
compatible with Modbus RTU/ TCP protocol.
With "remote control" as the functional core, it is highly easy to
use. Users can easily and quickly integrate into their own systems
to realize remote and local control based on Ethernet and
RS485/RS232.
- Wiring of Serial to Ethernet RTU ZHC1931
Connect the device to the computer with a network cable. After the
device is powered on, observe that the WORK indicator is always on,
which indicates that the network hardware environment of the device
is normal and can communicate with the device. After setting the
parameters of the ZHC1931, connect the network port of the network
device (router/switch/other) with the network port of the ZHC1931
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.
Application of Serial to Ethernet RTU ZHC1931
The product ZHC1931 has been widely used in the M2M industry of the
IoT industrial chain, such as smart grid, intelligent
transportation, smart home, finance, mobile POS terminals, supply
chain automation, industrial automation, intelligent building, fire
protection, public safety, environmental protection, meteorology,
digital medical, telemetry, agriculture, forestry, water, coal,
petrochemical and other related fields.
