A Serial to Ethernet converter is usually used to enable a device with a serial interface to connect to a remote computer over a network. Many industrial and consumer devices are equipped with RS232/RS422/RS485 ports. By using an RS232 to Ethernet converter you can access and control remote printers, barcode scanners, industrial monitoring sensors, and any other network-attached serial device from one central location. This saves time and increases your efficiency.
The COM to Ethernet connector works in either direction. The unit’s circuitry converts TCP/IP signals into serial data and serial transmissions into TCP/IP signals based on the input it receives.
Prior to using a Serial to Ethernet hardware solution, you will be required to install a software driver on your computer. This driver software, which is often referred to as virtual COM software, is commonly included with your converter purchase. The software creates a virtual serial port that is visible in Device Manager when the converter is connected to the machine.
If you are going to work with serial ports over network protocols, there’s a good chance that you’ll need a special tool called serial to Ethernet adapter (known alternatively as serial over Ethernet connector or device server). This solution is designed to convert data received from a serial port into TCP/IP data. The tool provides users with the ability to fully interact with remote COM ports without having them physically present on their local machines. Any remote serial port can be shared and accessed over the network with the help of COM to Ethernet solution.
