USR-TCP232-T1 is a new module launched by the Internet of Things to quickly realize the transparent transmission of network port and serial port data. All data protocol conversion is processed internally, and users only need to configure simple data to realize transmission from serial port to network end. The module comes with RJ45 network port, supports TCP/UDP protocol, DHCP and DNS functions, and can be configured through serial port AT commands, network configuration protocol, or built-in Web interface. The module is stable, reliable, and resistant to high and low temperatures, widely used in instrumentation, access control, smart home, industrial control, and medical equipment.
