Function description: Control the pulling, closing and releasing of four relays over the Ethernet, and configure module parameters over the network. The module supports both TCP and UDP2 modes of operation, and the instructions are simple and easy to understand, and the instructions can specify the point and 1-65535 seconds delay. The module is equipped with VB, Delphi host computer program and source code to help you easily achieve remote control of the computer. In TCP mode, the host computer can query the status of all relays, and after each instruction is processed, the module will return the status of all relays. There are no status queries or other returns in UDP mode, and the code is extremely simple and easy to embed in various applications. Now support cloud remote control, wechat remote control.
