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.
4.4.3 UDP Server
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.
4.4.4 UDP Client
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
