The 2-CH UART TO ETH 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, high stability, suits applications such as safety & security, IoT, and so on.
Examples Codes / Config Software / User Manauls
CH9121 is a network serial port transparent transmission chip, which can realize the two-way transparent transmission of serial data and network data. It supports 4 working modes of TCP CLIENT/SERVER, UDP CLIENT/SERVER, and the serial port baud rate support range is 300bps～921600bps, which needs to be configured before use. The host computer software NetModuleConfig.exe or serial command configures the network parameters and serial parameters of the chip. After the configuration is completed, CH9121 will saves the configuration parameters to the internal storage space. After the chip is reset, CH9121 will work according to the saved configuration values.
The UART2 is disabled, UART1 works in TCP CLIENT mode by default. The default setting of ETH is as below:
The default setting of the UART1 is as below:
