Serial to Ethernet provides the function of a serial server, and can easily realize two-way transparent transmission of data between RS232/485/422 serial ports and TCP/IP network interfaces without development. Wireless modem Through the serial port server, the serial port device can immediately have the function of TCP/IP network port, and can be connected to the network for data communication, expand the communication distance of the serial port device, and save manpower, material resources and development time.
Many industrial and consumer devices are equipped with RS232/422/485 ports. Convert between Ethernet via RS232. You can access and control remote printers, barcode scanners, industrial surveillance sensors and any other network-attached serial device from one central location.
Basic principles of serial server
In order to use such a device conveniently, we need to access the remote device. The easiest way is to send data from the serial port server to the remote server. A serial server is an electronic device or special software that converts RS232, RS485 or RS422 serial data signals into Ethernet. Software and hardware serial servers work the same way. The serial signal goes to the network connection and is converted to a proprietary network protocol (TCP/IP/Ethernet). To receive this connection on the remote computer, the RS232 converter does the opposite - again converting the network protocol to a serial signal.
Therefore, when working with serial devices, the importance of having an RS232 serial server is obvious. Remote access to serial devices or applications can be accomplished by the following methods.
If it is not possible to physically connect a COM port peripheral to a hardware RS232 serial server, a serial-to-Ethernet software can be used to share the device.
The application of the serial port server is not limited by the distance. It can connect to any number of remote COM ports from your computer, regardless of their physical location. To share a serial device to Ethernet, just install the program on the server client and configure the connection.
With its help, you can access serial ports supporting various protocols, no matter where your physical location is. No need to worry about the length of the cable connecting the serial device to the computer. Serial Server allows you to display and access serial ports converted to Ethernet as if they were on your local computer.
An RS232/485 to Ethernet hardware converter is actually a WIFI serial server compact server that connects autonomous devices with serial interfaces to Ethernet.
If you want to use a serial port with a network protocol, you will most likely need a special tool called an RS485 to Ethernet converter (also known as a serial server or device server). The program is to convert the data received by the RS232/485 port into TCP/IP data. This tool enables the user to fully interact with the remote COM port without actually displaying it on the local computer.
