3.2 Basic function

→Ethernet

3.2.1 SOCKET Function

E180-DTU (ZG120-ETH) can establish two-way sockets, respectively Socket A1 and Socket B1. Socket A1 supports

all types of TCP Client, TCP Server, UDP Client, and UDP Server. Socket B1 supports only three types: TCP Client, UDP

Client, and UDP Server.

Two sockets that run simultaneously can be connected to different networks at the same time for data transmission.

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

3.2.2 TCP Client Function

(1) TCP Client provides client connection for TCP network services. Actively initiate a connection request to the

server and establish a connection, which is used to implement the interaction between wireless data and server data.

According to the relevant provisions of the TCP protocol, TCP Client is distinguished from connected and disconnected,

thereby ensuring reliable exchange of data. It is usually used for data interaction between the device and the server, and is

the most commonly used network communication method.

(2) When E180-DTU (ZG120-ETH) attempts to connect to the server in TCP Client mode and the local port is 0, the

connection is initiated through a random port each time.

(3) E180-DTU (ZG120-ETH) supports short connection function.

(4) Under the same LAN, if E180-DTU (ZG120-ETH) is set to a static IP, please keep the IP of E180-DTU (ZG120-

ETH) and the gateway on the same network segment, and set the gateway IP correctly, otherwise normal communication

cannot be achieved.

3.2.3 TCP Server Function

(1) In TCP Server mode, E180-DTU (ZG120-ETH) monitors the local port. When a connection request is sent, it

accepts and establishes a connection for data communication. When E180-DTU (ZG120-ETH) receives the data, it

will simultaneously send the data to all client devices that have established a connection with it.

(2) It is usually used for communication with TCP clients in a LAN, which is suitable for the scenario where there is

no server in the LAN and there are multiple computers or mobile phones requesting data from the server. Like TCP

Client, there are differences between connection and disconnection to ensure reliable exchange of data.

(3) When E180-DTU (ZG120-ETH) is used as TCP Server, it can accept a maximum of 6 Client connections (the

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

number of connections can be customized). The local port number is a fixed value and cannot be set to 0.

(4) TCP Server can set the maximum number of connections. When the maximum number of connections is

reached, user can choose to kick off the old connection or prohibit the establishment of new connections according to

the configuration through commands.

3.2.4 UDP Client Function

(1) UDP Client is a disconnected transmission protocol that provides transaction-oriented simple and unreliable

information transmission services. There is no connection establishment and disconnection, only the IP and port are

required to send data to each other. Usually used for data transmission scenarios where there is no requirement for packet

loss rate, data packets are small and transmission frequency is fast and data is to be transmitted to the specified IP.

(2) In UDP Client mode, E180-DTU (ZG120-ETH) only communicates with the target port of the target IP. If the

data is not from this channel, it will not be received by E180-DTU (ZG120-ETH).

(3) In UDP Client mode, if the destination address is set to 255.255.255.255, it can achieve the effect of UDP broadcast

on the entire network segment, and it can also receive broadcast data. E180-DTU (ZG120-ETH) module supports

broadcasting within the network segment , such as xxx.xxx.xxx.255 broadcast mode.

3.2.5 UDP Server Function

(1) UDP Server means that the source IP address is not verified on the basis of ordinary UDP. After receiving a UDP

data packet, the destination IP is changed to the data source IP and port number. When sending data, send to the IP and

port number of the most recent communication.

(2) This mode is usually used for data transmission scenarios where multiple network devices need to communicate

with the module and do not want to use TCP due to the fast frequency.

Note: UDP Server cannot send data actively. Only after receiving the data can it send data to the IP and port that have

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

recently exchanged data.

→Wireless

3.2.6 ZigBee Device type

There are three types of logical devices in the ZigBee network: Coordinator, Router, End-Device (Non-dormant

terminal) and Sleep- End-Device (Dormant terminal). ZigBee network consists of a Coordinator, multiple Routers, and

multiple End Devices (its terminal nodes can be divided into dormant and non-dormant terminals).

3.2.6.1 Non-dormant terminal

The main task of a terminal device is to send and receive messages. No other nodes are allowed

to connect to the terminal device. Non-dormant terminal is always in operating mode and can receive

and send data at any time.

3.2.6.2 Dormant terminal

When wireless data needs to be sent or command operations needs to be performed, wake-up frame needs to be sent

through the serial port first, and the length needs to be 25 bytes or more ("FF FF FF FF FF FF FF FF FF FF FF FF FF FF

FF FF FF FF FF FF FF FF FF FF "25-byte" FF "wake-up), the wake-up time lasts 1000ms, during which serial port data

(configuration commands, payload) can be processed, and when a frame of serial port data is successfully received, the

timeout counter will be refreshed, and the wake-up duration will be 1000ms later, otherwise the device will enter sleep

again;

When data needs to be received, it is received through periodic wake-up. The longer the wake-up period is set, the

more the reception is delayed. The wake-up period must be set to less than 30 seconds.

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

3.2.6.3 Router

Allow other nodes to connect with the routing device to expand the coverage of the network. Its main task is to

forward packets, play the role of relay routing, and have all the functions of terminal device. If there are multiple paths

from one node to another, when one of the them fails, the network will automatically adjust to the other optimal path for

transmission to ensure data arrival. The router can establish its own network or join other people's networks, it is always

active and that is why it must be powered by the main power supply.

3.2.6.4 Coordinator

It has the functions of establishing and managing the network, controlling whether other nodes are allowed to join

the network, storing network information, and having all the functions of the routing device. Its main tasks are to manage

the network, record child node information, and forward messages. At the same time, the coordinator needs to

authenticate the permissions of the terminal requesting network access.

3.2.7 Data transmission method

The data transmission methods of E180-DTU (ZG120-ETH) include unicast, broadcast, and multicast.

3.2.7.1 Broadcast mode

In broadcast mode, the sending device sends the data received by the serial port to each node (including itself) in the

network, and all devices in the network will receive the data.

3.2.7.2 Multicast mode

In multicast mode, first set the group number (grouping) of the devices in the network, the sending device must

specify the destination group number (to which group the data is sent), and then the sending device sends the data

received by the serial port to the network, devices with the same group number in the network will receive data.

3.2.7.3 Unicast mode

In unicast mode, the devices in the network perform point-to-point communication through the network address.

The sending device sends the received serial data to the target address device. After receiving the data, the target address

device can return an ACK to the sending device to indicate that it has received data.

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

3.2.8 Output mode of receiving data

Receiving data output mode refers to the mode in which the network outputs data after E810-DTU (ZG120-ETH)

receives wireless data;

3.2.8.1 Transparent output

If output mode of the configuration device is transparent output, the module outputs the original data through the

serial port after receiving the wireless data;

3.2.8.2 Data+Short address

When output mode of the device is data + short address, after the module receives wireless data, serial port will

output the original data + the short address of the sending device.

3.2.8.3 Data+Long address

When output mode of the device is data + long address, after the module receives wireless data, serial port will

output the original data + the long address of the sending device;

3.2.8.4 Data+RSSI

When output mode of the device is data + RSSI, after the module receives wireless data, serial port will output the

original data + the RSSI value of the received data packet;

3.2.8.5 Data+Short address+RSSI

When output mode of the device is data + short address + RSSI, after the module receives wireless data, serial port

will output the original data + the short address of the sending device + the RSSI value of the received packet;

3.2.8.6 Data+Long address+RSSI

When output mode of the device is data + long address + RSSI, after the module receives wireless data, serial port

will output the original data + long address of the sending device + RSSI value of the received data packet.

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

Note: The sender's single packet supports a maximum data packet length of 72 bytes

3.3.2 Heartbeat packet

In the network transparent transmission mode, users can choose to let the E180-DTU (ZG120-ETH) send heartbeat

packets. Heartbeat packets can be sent to the web server. The main purpose of sending to the network is to maintain a

connection with the server. It only takes effect in TCP Client and UDP Client modes. E180-DTU (ZG120-ETH) module

supports up to 60 bytes of custom heartbeat packet content.

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

3.3.3 Registration packet

In the network transparent transmission mode, users can choose to let the DTU send a registration packet to the

server. The registration package is to enable the server to identify the data source device or as a password to obtain server

function authorization. It can be sent when the DTU establishes a connection with the server, or the registration packet

data can be spelled into the front end of each data packet as a data packet. The data of the registration packet can be

MAC address or custom registration data the content of the custom registration packet setting is up to 60 bytes.

Establishing connection and sending registration packet are mainly used to connect to a server that needs to be

registered.

3.3.5 Short connection

The use of TCP short connection is mainly to save server resources and is generally applied in multi-point-to-point

scenarios. The use of short connection can ensure that all existing connections are useful and do not require additional

control measures to filter.

The TCP short connection function is applied in the TCP Client mode. After the short connection function is enabled,

send the information, if there is no data received via serial port or network port within the set time, the connection will be

automatically disconnected. The short connection function is turned off by default. The disconnection time can be set after

the function is turned on, and the setting range is 2 ~ 255S.

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

3.3.6 KeepAlive

Keep-Alive is a mechanism for detecting dead connections in TCP connections. When users does not send any data,

TCP link will periodically send "Keep-Alive" information to maintain the idle link, avoiding dead connections

consuming unnecessary system resources. This setting is valid under TCP. Users can customize the Keep-Alive switch

and other parameters.

Keepalive parameters:

Time: Start probe message after how many seconds the TCP link has no data message transmitted ;

Intv: Time interval between the previous probe message and the next probe message;

Probes: Maximum number of probe failures. When the number of sniffing failures reaches this number, TCP

connection will be disconnected.

3.3.7 Timeout restart

Timeout restart (no data restart) function is mainly used to ensure the long-term stable operation of E180-DTU

(ZG120-ETH). When the network port cannot receive data for a long time or the network has not received data for a long

time, E180-DTU (ZG120- (ETH) will restart after exceeding the set time so as to avoid abnormal conditions affecting

communication. The timeout restart can be set via the web page. The normal working time of this function is set to 60 ~

65535S, and the default value is 3600S. 0 is off,and it returns to the default value when the setting exceeds the range.

3.3.8 Clear cache

When TCP connection is not established, the data received by DTU will be placed in the cache area. E180-DTU

(ZG120-ETH) receiving cache is 2Kbyte. After TCP connection is established, the network cache data can be set to be

cleared according to customer needs.

The device has two cache areas, namely the serial data cache area and the network data cache area. When SOCKET

clear cache function is enabled, only the cache data of the relevant SOCKET link will be cleared and the serial port cache

data will not be cleared.

Chengdu Ebyte Electronic Technology Co.,Ltd E180-DTU(ZG120-ETH)User Maunel

3.3.9 Link/Data receiving and sending command

Link indicates network connection state. In TCP mode, Link is off when the network is not connected. When the

connection is established, Link is always on. The Link indicator is always on in UDP mode.

The other is a data transmission indication, which shows the transmission state of DTU. When there is no data

transmission on DTU, the data transmission indicator is off. When there is data transmission on DTU, the flashing indicates

that its period is 60ms and the indicator is on for 10ms.

3.3.10 Restore factory setting
