for data communication when a connection request is sent. When the E810-DTU(RS232)-V2.0 serial port receives data,
it will transmit data to all client devices which established a connection with the E810-DTU(RS232)-V2.0.
(2) It is usually used for communication with TCP clients in the LAN. Suitable for scenarios where there is no
server in the LAN and there are many computers or cellphones requesting data from the server. There is difference
between connection and disconnection like TCP Client to ensure the reliable exchange of data.
(3) When the E810-DTU(RS232)-V2.0 is a TCP Server, it can connect at most six clients, the local port number is
a fixed value and cannot be set to 0.
4.2. TCP Client characteristics
Figure 4 TCP Client
(1) TCP Client provides Client connectivity for TCP network services. Proactively initiates connection requests to
the server and establishes connections for the interaction of serial data and server data. According to the relevant TCP
protocol, there is difference between connection and disconnection to ensure the reliable exchange of data. It is normally
used for data exchange between devices and servers and it is the most commonly used networking communication
method.
(2) In TCP Client mode, when the E810-DTU(RS232)-V2.0 attempts to connect to the server and the local port is 0,
it initiates a connection with a random port each time.
(3) This mode supports short connection function
。
(4) In the same LAN, if the E810-DTU(RS232)-V2.0 is set to static IP, please keep the E810-DTU(RS232)-V2.0 IP
and gateway in the same network segment and set the gateway IP correctly, otherwise it cannot communicate normally.
