4. Network communication mode selection, there are 5 communication methods
4.1 UDP, is a connectionless transmission communication protocol, here is the UDP CLIENT
mode, providing simple and unreliable Information transfer service, no connection
establishment and disconnection, small data packets and high transmission frequency, there is
no requirement for packet loss. data to be transmitted to the specified IP. This mode is not
recommended.
4.2 TCP Client The factory default mode of this device is to provide client connections for TCP
network services and actively connect to the server. There is a difference between connection
and disconnection, thus ensuring reliable data exchange.
4.3 UDP Server UDP server mode, opposite to UDP Client. Setting this mode is the UDP server
mode. It is also an unreliable connection. It is not recommended to work in this mode.
4.4 TCP Server TCP server mode, corresponding to TCP Client mode, if set to this mode, this
device will serve to use the server, the computer needs to be set to the client mode for
communication and actively connect to this device.
4.5 HTTPD Client needs an HTTP server. The URL, header, domain name, port and other
information needed to send data can be
It can be set through software. When sending data, you only need to send the request data.
The device comes with the URL and header, and the returned data the user can choose
whether to remove the header.
The above 4.1-4.5 only briefly explained these communication methods. For more detailed
information, please refer to the USR-K3 software setup manual book.
The factory default is TCP Client mode.
Then set the remote IP remote port and local port. The remote port supports the way to enter the
domain name: for example www.xxx.com can also directly enter the IP address. The remote port
refers to the port allowed to connect to the server.
Note: When doing experiments in a local area network, make sure that the device and the
communicating computer are in the same network segment
