3. Introduction of functions
3.1 Typical application model
3.2 ZigBee Basic functions
ZigBee The parameters are configured through the billion-tech ZigBee3.0 upper machine!!!
3.2.1 ZigBee Network introduction
There are 3 logical device types in the ZigBee network: Coordinator (coordinator), Router (router), and End-Device
(terminal). The ZigBee network consists of one Coordinator along with multiple Router and multiple End_Device.
3.2.1.1 Coordinator
It has the function of establishing and managing the network, controlling whether other nodes are allowed to join the
network, store the network information, and has all the functions of the routing equipment. Its main tasks are to manage the
network, record the information of child nodes, and forward messages. In the meantime, the coordinator needs to identify the
terminal permission to request the network access. Without the need of new nodes, the network will not crash after the
coordinator is powered off, and the router and terminal will work normally in the current network.

3.2.1.2 Router
The router allows other nodes to be connected to the routing device to expand the coverage of the network. Its main task is
to forward messages, relay routing, and have all the functions of the terminal equipment. If there are multiple paths from one
node to another node, when one of the paths fails, the network automatically adjusts to the other optimal path for transmission to
ensure that the data arrives. The router can build its own network or join someone else's network. The router is always active, so
it must be powered by the main power source.
3.2.1.3 Terminal
The main task of the terminal equipment is to send and receive messages, and it does not allow other terminal nodes to be
connected to the terminal equipment. The terminal is always in a working state and can receive and send data at any time.
3.2.2 Data transmission method
E180-DTU (Z20-ETH) sends three kinds of data transmission methods, including unicast, broadcast and multicast.
3.2.2.1 Broadcast mode.1
In the broadcast mode, the transmitting device sends the data received by the serial port to each node in the network
(including itself), and all the devices in the network will receive the data.
3.2.2.2 Hoost mode.2
In the multicast mode, the group number is set (grouped) for the devices in the network, the sending device must specify
the target group number (which group to send data), and then the sending device sends the data received by the serial port to the
network, and the device with the same group number in the network will receive the data.
3.2.2.3 Monocast mode.3
In the unicast mode, the device in the network conducts point-to-point communication through the network address, and the transmitting
device sends the received data to the target address device, and the target address device can return an ACK to the transmitting device to
indicate that the data has been received.
3.2.3 Output mode of receiving data
The receiving data output mode refers to the mode of the network output data when E180-DTU (Z20-ETH) receives the
wireless data;

3.2.3.1 Transparent output.1
If the output mode of the configured device is transparent output, the module receives the wireless data and outputs the raw
data through the network port.
3.2.3.2 HEX instruction format output
When the output mode of the device is in the HEX instruction mode, the output data is output with the ZCL instruction in
the HEX instruction, and the HEX instruction identifies the transmission source of the data and the signal strength of the data;
3.3 Network parameters
Network parameters can be configured through the EBYTE network configuration tool and web pages!!!
EBYTE network configuration tool can click the network configuration button in ebai ZigBee 3.0 upper computer: open
ZigBee 3.0 upper computer, click Ethernet connection, click network configuration, enter EBYTE network configuration tool.

3.3.1 IP address type
The IP address is the identity identification of modules in the LAN, and it is unique in the LAN. Therefore, it cannot be
repeated with other devices of the same LAN. The IP address of the module has two acquisition methods: static IP and DHCP.
Static IP: Static IP needs to be set manually by the user. In the process of setting, pay attention to write IP, subnet mask and
gateway at the same time. Static IP is suitable for scenes that need statistics of IP and devices and correspond to them one to one.
Advantages: Devices that cannot be assigned IP address can be searched through the whole network segment broadcast
mode, convenient for unified management;
Disadvantages: different LAN Intranet segments, resulting in no normal TCP / UDP communication.
Dynamic DHCP: The main function of DHCP is to dynamically obtain IP address, gateway address, DNS server address
and other information from the gateway host, so as to avoid the cumbersome steps of setting IP address. It is applicable to the
scenarios where there are no requirements for IP, and it does not require IP to correspond to modules one by one.
Advantages: Access routers and other devices with DHCP Server can be directly communicated, reducing the trouble of

14
setting the IP address gateway and subnet mask.
Disadvantages: Access to no DHCP Serve r network, such as direct connection to the computer, the module will not work
properly.
The subnet mask is mainly used to determine the network number and host number of the IP address, indicate the number
of subnets, and determine whether the module is in the subnet.
The subnet mask must be set. We commonly used class C subnet mask: 255.255.255.0, network number is the first 24,
host number is the bottom 8, the number of subnets is 255, module IP is within 255, so module IP is considered in this subnet.
Gateway is the network number of the network where the current IP address is located. If a device like a router is
connected when connected to an external network, the gateway is the route.
3.3.2 Domain name Resolution (DNS)
Domain name resolution transforms a domain name into a network-recognized IP address via the Domain name
Resolution (DNS) server. Serial port server domain name resolution (DNS) server address support user customization, in the
domain name server exception by custom domain name resolution server implementation domain name resolution, device in the
domain name resolution to the custom domain name resolution (DNS) server report resolution request, resolution after returning
the device connection parameters (generally IP address).
In DHCP mode, the domain name resolution (DNS) server address automatically obtains (synchronize the router domain
name resolution address) and cannot be modified.
In the static IP mode, the default address of the Domain Name Resolution (DNS) server is 114.114.114.114.
3.3.3 Intranet access port
The Intranet access port will default to 80.
[Note] If the port number is modified, the port number should be added to the address input bar. For example, modify the
web page access port to 8080, and the connection web page configuration needs to enter 192.168.3.7:8080 in the address bar.

3.4 Network working mode
3.4.1 TCP server mode
TCP Server The TCP server. In TCP Server mode, the device listens to the native port, accepts connection requests from
the client and establishes a connection for data communication, usually for the communication with the TCP client within the
LAN.
When the Modbus gateway function is turned off, the device will send the data received by the serial port to all client
devices connected to the device, supporting up to 6 clients. After the Modbus gateway function is enabled, non-Modbus data
will be cleared without forwarding.
3.4.2 TCP client mode
TCP Client The TCP client. When the device is working, it will actively initiate a connection request to the server and
establish a connection to realize the interaction between serial port data and server data.
Using the client needs to accurately configure the IP address / domain name, destination port of the target.

3.4.3 The UDP Server mode
UDP Server Means that the device does not verify the data source IP address when communicating with the UDP protocol.
After you receive each UDP packet, save the source IP address and the source port and set it as the target IP and port, so the data
sent by the device only sends the packet to the source IP address and port of the last time that the device receives the data.
This mode is usually used for scenarios where multiple network devices communicate with the device and the frequency is
high and TCP Server cannot meet the conditions.
Using UDP Server requires the remote UDP device to send the data first, otherwise the data cannot be sent
normally.
[Note] In UDP mode, the network should send data to the device less than 512 Bit per package, otherwise it will cause data loss.
3.4.4 The UDP client mode
UDP Client A non-connected transmission protocol that provides a simple and unreliable information transmission service
oriented to transactions. Without connection establishment and disconnection, it only needs to configure the destination IP and
destination port to send the data to the other party. It is usually used for data transfer scenarios with no requirements for packet
loss rate, small packets and fast transmission frequency, and data to be transmitted to the specified IP.

In UDP Client mode, the device will only communicate with the configured (destination IP and destination port) remote
UDP device.
In this mode, the target address is set to 255.255.255.255, and the sent data will be broadcast in the whole network segment,
but the transceiver device should ensure the same port, and the device can also receive the broadcast data.
3.4.5 HTTP client mode
This mode can realize the function of HTTP group package, provides GET and POST mode, customers can configure URL,
Header and other parameters, sent by equipment (serial server), realize the rapid communication of serial devices and HTTP
server, using the HTTP client mode suggest to use random port and open short connection, save HTTP server resources.
