3. Function description
3.1 Typical application model
3.2 Basic function
→Ethernet
3.2.1 SOCKET
E800-DTU(Z2530-ETH-27) can establish two-way sockets, 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 run simultaneously can be connected to different networks at the same time for data transmission.
3.2.2 TCP Client
(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 E800-DTU(Z2530-ETH-27) 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)E800-DTU(Z2530-ETH-27) supports short connection function.
(4) Under the same LAN, if E800-DTU(Z2530-ETH-27) is set to a static IP, please keep the IP of E800-DTU(Z2530-

Chengdu Ebyte Electronic Technology Co.,Ltd E800-DTU(Z2530-ETH-27) User Manual

ETH-27) and the gateway on the samenetwork segment, and set the gateway IP correctly, otherwise normal communication
cannot be achieved.
3.2.3 TCP Server
(1) In TCP Server mode, E800-DTU(Z2530-ETH-27) monitors the local port. When a connection request is sent, it
accepts and establishes a connection for data communication. When E800-DTU(Z2530-ETH-27) 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 but 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 E800-DTU(Z2530-ETH-27) is used as TCP Server, it can accept a maximum of 6 Client connections (the
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,
users 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
(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.

Chengdu Ebyte Electronic Technology Co.,Ltd E800-DTU(Z2530-ETH-27) User Manual
Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co.,Ltd 8
(2) In UDP Client mode, E800-DTU(Z2530-ETH-27) only communicates with the target port of the target IP. If the
data is not from this channel, it will not be received by E800-DTU(Z2530-ETH-27).
(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. E800-DTU(Z2530-ETH-27) module supports
broadcasting within the network segment , such as xxx.xxx.xxx.255 broadcast mode.
3.2.5 UDP Server
(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
recently exchanged data.

mode is off). Note: It is recommended that the sleep time must be shorter than the data retention time of the parent node,
otherwise it will affect data reception
5
Short address communication is used for network communication. Note: The short address is randomly assigned when the
device joins the network. The long address of the device MacAddress is the only fixed one. Check the short address of the
network on the WEB page and then perform point-to-point communication.
6
The coordinator is unique in the network and the short address is fixed at 0000.
7
If the unicast address is FFFF, FFFD, FFFC, they correspond to three broadcast modes respectively.
8
It is automatically assigned when the network parameter PANID is FFFF. If the device PANID is different, it cannot be
networked.
9
The network key cannot join the network at the same time. E800-DTU (Z2530-ETH-27) network key is all on, and users
cannot capture the correct air data through software capture.
10
All devices in the network have the broadcast function enabled. Multiple devices broadcasting at the same time or a single
device with a higher frequency of broadcasting may cause serious network congestion. Please try to avoid this situation.
11
E800-DTU (Z2530-ETH-27) does not need to join this group when multicast. It can directly multicast to any group
according to the communication usage method. After multicast, the local group number does not change due to different
multicast numbers。
12
In the sleep state, the first frame of data is invalid for wake-up.
13
For communication in the ZigBee network, the single packet data sending cycle cannot be too fast (generally recommended
above 1 second). Too fast may cause data loss. (Note: there are too many nodes in the network, and the broadcast cycle is
too fast may cause network instability.)
14

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.
3.3.6 KeepAlive
Keep-Alive is a mechanism for detecting dead connections in TCP connections. When there is no data sent by
users , 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: 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 datarestart) function ismainly used to ensurethelong-term stable operation of E800-DTU(Z2530-
ETH-27). When the network port cannot receive data for a long time or the network has not received data for a long time,
E800-DTU(Z2530-ETH-27) 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. E800-
DTU(Z2530-ETH-27) receiving cache is 2Kbyte. After TCP connection is established, the network cache data can be set
to be cleared or not according to customer needs.
