(4) Under the same LAN, if E810 (4RS1E) is set to static IP, please keep the IP of E810 (4RS1E) and the gateway on the same

network segment, and set the gateway IP correctly, otherwise communication will not be normal.

4.3. UDP Server Mode characteristic

Diagram 4-4 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

each time, 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 DTU and

do not want to use TCP due to the fast frequency.

Diagram 4-5 UDP Client

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

transmission services. There is no connection and disconnection establishment. IP and port needed to be specified can send data to

the other party. 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, E810 (4RS1E) will only communicate with the target port of the target IP. If the data is not from this

channel, the data will not be received by E810 (4RS1E).

(3) In UDP Client mode, if the destination address is set to 255.255.255.255, the effect of UDP full network segment broadcast

can be achieved, and broadcast data can be received at the same time. E810 (4RS1E) DTU supports broadcast within network

segment, for example, xxx. the broadcast mode of xxx.xxx.255.
