channel server mode, each server can access 2 client devices, or if the device is in the one channel

server mode, the server can access 9 client devices. If the number of client devices exceeds the

access limit, The device will perform a connection rejection.

4.4.2 TCP Client

TCP Client refers to the TCP client. When the device is working, it will actively initiate

connection requests to the server and establish a connection, which is used to achieve the interaction

between serial port data and server data.

To use the client, it is necessary to configure the IP address/domain name and target port of the

target accurately.

Eight channels can independently open eight TCP clients.

UDP Server refers to a device that does not verify the source IP address of data when

communicating using the UDP protocol. After receiving each UDP packet, it saves the source IP

address and source port of the packet and sets it as the target IP and port. Therefore, the data sent by

the device only sends the packet to the source IP address and port where the last device received the

data.

This mode is usually used in scenarios where multiple network devices communicate with this

device and the frequency is high, and TCP Server cannot meet the conditions.

Using UDP Server requires remote UDP devices to send data first, otherwise data cannot be sent

normally.

[Note] In UDP mode, the data sent by the network to the device should be less than 512Bit per

packet, otherwise it may cause data loss.

UDP Client is a connectionless transmission protocol that provides simple and unreliable

information transmission services for transactions. There is no connection establishment or

disconnection, and data can be sent to the other party by configuring the destination IP and
