USR-TCP232-T1/S1 is a new module launched by the Internet of Things to quickly realize the transparent transmission of network port and serial port data transmission. All data protocol conversion is processed internally, and users only need to configure simple data to realize the transmission of data from the serial port to the network end. The product comes with RJ45 network port, supports TCP/UDP protocol, DHCP and DNS functions, product parameters can be configured through serial port AT, network configuration protocol or built-in Web, simple and fast. The product is stable and reliable, resistant to high and low temperatures, and the two packages can be integrated into the embedded development board faster. The products are widely used in application scenarios such as instrumentation, access control, smart home, industrial control machine, and medical equipment.
