Functions of Serial to Ethernet converter

There is something in common in serial printers, barcode scanners, scales, GPS, surveillance cameras, and serial consumer/industrial devices, they all use the RS232, RS485, or RS422 serial interface to connect and to interact with the computer. This article explains how to connect serial to Ethernet converter to the computer.


If the above devices want the access the Ethernet or the LAN, we can use the device that has serial to Ethernet converter function, which is called the serial to Ethernet converter. Take USR-TCP232-410S as an example, which is developed and manufactured by USR IOT.


USR-TCP232-410S is an industrial serial to Ethernet converter, which can convert the serial data into Ethernet IP/TCP data. Here follow the features of USR-TCP232-410S:

10/100Mbps Ethernet interface and support Auto-MDI/MDIX.

Support TCP Server, TCP Client, UDP Client, UDP Server, HTTP Client. 

Support configuring through Web Server 

Support RS232 and RS485 and they can work independently.

Support RTS/CTS hardware flow control and Xon/Xoff software flow control.

Support USR-VCOM.

Support Modbus Gateway. 

Support serial port baud rate 600bps-230.4K bps; support None, Odd, Even, Mark, Space parity way.

Support Static IP or DHCP. 

Support Websocket function.

Support the Reload button to reset to default settings by hardware way.

Support Keep-alive. 

Support timeout restart function and timeout reconnect function.


How to set serial to Ethernet converter USR-TCP232-410S: 

Download a V-COM(Virtual com port drive) from

Through this software user can set up a connection between 410s and virtual serial to solve the problem that traditional equipment PC software used in serial port communication way.
