Serial to TCPIP Converter
RS232/RS422/RS485 Serial Converter
A serial to Ethernet converter is a small electronic device which can convert Ethernet IP / TCP packets to either RS232, RS485 or RS422 serial data signals and vice versa. It is also sometimes called a serial device server and it comes in several different shapes and sizes.
Most commonly it is used for connecting a serial RS232, RS485 or RS422 device such as a serial printer, barcode scanner, scale, GPS, sensor or any other consumer or industrial device with a serial interface, to a computer over a standard LAN network. The advantage of this is obvious; you will be able to control, monitor and communicate with your serial device remotely from a central computer. No need to walk all the way down to the other end of the factory to check your serial device.
The circuitry inside the converter can convert IP / TCP packets to serial data and also convert serial data to IP / TCP packets, so it works in both directions.
Before you can start using the converter you need to install driver software on your computer. This driver software is also called virtual COM software because it creates a virtual COM port in your computer's Device Manager when the converter is connected to your computer. Virtual COM software is usually included with the converter.
