Three Types of Serial Device Server

There are three types of serial device servers: single-port serial device server, multi-port serial device server, and wireless serial device server (WIFI serial to Ethernet converter)


The single-port serial device server

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.


The multi-port serial device server

Serial device servers are typically available for 1 to 48 COM ports. However, the number of ports may vary by manufacturer. A serial device server with 1 to 8 COM ports is called multi-port serial device server. The representative product is USR-TCT232-410s; the market price is $39.


The multi-port serial device server both support RS232 and RS485 port, the two ports can work independently at the same time without affecting each other.

Support RTS/CTS hardware flow control function, support Xon/Xoff software flow control.

Support virtual serial port software (USR-VCOM).

Support Modbus gateway function, and it is more convenient to use on the industrial site.

Support timeout restart and timeout reconnection.

Support one-way Websocket function to realize bidirectional transmission of data between webpage and serial port.


WIFI serial device server

If you need to connect a serial or Ethernet device to a wireless LAN, you can also try using a WIFI serial device server. The representative product is USR-W600; the price is $26.00.
