Introduction of 4G DTU ZHC4012
ZHC4012 is a product developed to realize the mutual data
transmission between serial device and network server through the
operator's network. By simply setting via upper computer, you can
easily use this product to realize the two-way data transparent
transmission from the serial port to the network. ZHC4012 support
standard MQTT and Modbus Protocol, which can be widely used in
power system, industrial monitoring, traffic management,
environmental monitoring, meteorology, water conservancy, coal,
petroleum, new energy and other industries.
