Chapter 1 Product Introduction
1.1 Product Introduction
E18-DTU(Z20-485), E18-DTU(Z27-485) is a wireless data transceiver based on ZigBee3.0
technology, with transparent transmission, protocol transmission, and other functions. As a
communication medium, wireless data transceiver has a certain scope of application like optical fiber,
microwave, and wire; It provides real-time and reliable data transmission of monitoring signals in
private networks under certain special conditions, and has the advantages of low cost, easy installation
and maintenance, strong diffraction ability, flexible network structure, and long coverage. It is suitable
for occasions with many scattered points and complex geographical environments. It can also be
connected with data terminals such as PLC, RTU, rain gauge, and liquid level gauge.
1.2 Function Features
★ All core components are imported with original packaging. Compared with the current similar imported digital radios, it has the
most advanced functions, the smallest volume and the best price.
★ Multi-level transmitting power is available .
★ Working temperature: -40℃
～
+85℃, suitable for various harsh working environments, it is a real industrial grade product.
★ All aluminum alloy shell, compact size, easy installation, good heat dissipation; perfect shielding design, good electromagnetic
compatibility, and strong anti-interference ability.
★ Power supply reverse connection protection, over-connection protection, antenna surge protection and other multiple protection
functions greatly increase the reliability of the radio.
★ Powerful software function, all parameters can be set by programming: such as power, frequency, address ID, etc.
★ Built-in watchdog, with precise time layout, once an abnormality occurs, the module will automatically restart, and can continue
to work according to the previous parameter settings.
1.3 Product Features
