USR-TCP232-304 is one of the most popular single-port serial device server with built-in Web server function.  If the prices of serial device servers in the market are less than 100 yuan, and those are cost-effective serial device servers. In industrial projects, semi-duplex RS485 ports are widely used and can be connected to multiple terminals in parallel. USR also has the RS232 serial device server—USR-TCP232-302 with same functions.
