This mode is usually used in scenarios where multiple network devices communicate with this device, and the
frequency is high, and the TCP Server cannot meet the conditions.
Using UDP Server requires the remote UDP device to send data first, otherwise the 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 will cause data loss
4.3.4 UDP Client Mode
UDP Client is a connectionless transmission protocol that provides transaction-oriented simple and unreliable
information transmission services. There is no connection establishment and disconnection, and data can be sent to
the other party only by configuring the destination IP and destination port. It is usually used in data transmission
scenarios where there is no requirement for the packet loss rate, the data packets are small and the transmission
frequency is fast, and the data is to be transmitted to the specified IP.
In UDP Client mode, the device will only communicate with the configured (target IP and target port) remote
UDP devices.
In this mode, the target address is set to 255.255.255.255, and the sent data will be broadcast on the entire
network segment, but the transceiver device needs to ensure that the ports are consistent, and the device can also
receive broadcast data.
4.3.5 HTTP Client Mode
This mode can realize the function of HTTP grouping. It provides two modes: GET and POST. Customers can
configure URL, Header and other parameters by themselves, and the device (serial port server) will send packets to
realize fast communication between the serial port device and the HTTP server. In HTTP client mode, it is
recommended to use random ports and enable short connections to save HTTP server resources.
