Waveshare 2-CH UART To Ethernet Converter, Serial Port Transparent Transmission Module – Pinnacle

2-CH UART To Ethernet Converter-The Waveshare 2-CH UART To Ethernet Converter provides an easy way to communicate between UART TTL and RJ45 Ethernet, allowing bi-directional transparent data transmission. It is easy to use, along with features like fast data rate, low power consumption, and high stability, and suits applications such as safety & security, IoT, and so on.CH9121 is the chip for network serial port transparent transmission, which can realize the two-way transparent transmission of serial data and network data. It supports 4 working modes such as TCP CLIENT, SERVER, UDP CLIENT and SERVER, and the serial port baud rate is 300bps～921600bps. Before use, it is necessary to configure the network parameters and serial port parameters of the chip through the host computer software NetModuleConfig.exe or serial commands. After the configuration is completed, CH9121 will save the parameters to the internal storage space. After the chip is reset, CH9121 will work according to the saved configuration values.Revolutionize the way you connect and communicate with the Waveshare 2-CH UART To Ethernet Converter.
