Many diverse peripheral devices communicate with computers through an RS232, RS485 or RS422 serial cable connection. Some examples are GPS units, industrial monitoring devices, serial printers, surveillance cameras, and point-of-sale barcode scanners, to name just a few. Gaining access to these devices from a remote computer can be a problem that we aim to solve with some outstanding options.
There is both a software and a hardware solution that allows you to access these serial devices over the Ethernet or LAN, or for converting serial port traffic to IP. The software solution is Serial to Ethernet Connector, while you can use any hardware with serial port to Ethernet adapter capabilities.
We will first look at the software solution, which is called Serial to Ethernet Converter and was developed by Eltima software.
Serial to Ethernet Connector
Requirements: Requirements for Windows (32-bit and 64-bit): XP/2003/2008/ Vista/7/8/10, Windows Server 2012. 4.66MB free space. Version 7.1.876. (27th Jan, 2017). 4.9 Rank based on 52+ users, Reviews(86) Category: Communication Application
To use the Serial to Ethernet Adapter, download and install the app, it will display a list of devices available to you, find the one you need and connect to it. With the help of the software you will easily access the serial port over LAN.
Software Serial to Ethernet Adapter
Serial to Ethernet Adapter allows you to remotely access serial port devices that are locally attached to a network connected computer. This RS232 to Ethernet adapter lets your remote machine work with serial devices in the same way as if they were directly connected to your computer, without the need for any additional software. You can create and share over 500 serial port devices simultaneously over your TCP/IP network.
How to use Serial to Ethernet Adapter: To begin you need to install the COM port to ethernet adapter software on every computer that will be sharing the serial device.
After installation, launch the application and your serial device will be accessible by any network attached computer that is running the serial to Ethernet adapter software.
Serial to Ethernet Adapter facilitates the conversion of COM port data to the Ethernet. Once converted, the data can then be shared over the network. Your remote computer displays a virtual serial connection that enables communication between the port and the software.
Running as a Windows service is a significant feature of this serial to LAN adapter software and guarantees that all of your connections are reconfigured automatically when your system is rebooted. This also means that you can close the interface as it is always running in the background. Another nice feature is that Serial to Ethernet Adapter lets you use a backup to transfer configurations between computers.
This excellent RS485 to Ethernet adapter solution can be run on Windows or Linux platforms. Either platform can play the part of server or client, and broadcasting over UDP is supported. Note, that currently there is only a command-line version for Linux.
Hardware Solutions that can convert serial ports to Ethernet:
You are also may use the hardware Serial to Ethernet Adapter. It will convert your serial port signals to the network protocol and you will get the remote access to the RS232 device.
RS232, RS485 or RS422 serial data signals are converted to TCP/IP packets by this small electronic device. The conversion works in both directions when using this RS485 to ethernet adapter. One drawback to this hardware solution is that you are bound by the fixed number of ports supported by the device. Serial to Ethernet Converter is relatively simple to use and set up. Knowledge of your network settings and the computers that will be connected will streamline the setup process.
How it works: There is circuitry built into the RS232 over Ethernet adapter that converts between serial data and TCP/IP packets in either direction.
Setup guide: First install the driver that is provided with the hardware (alias virtual COM software). After installation, you will be able to use the virtual COM software and create a virtual COM port. Once the hardware is connected to your computer, you can create the virtual ports in Device Manager.
Now you can connect the COM to LAN adapter to a power supply and your computer with the standard cable included with the hardware. Then you enter the hardware’s IP address into your browser’s address bar and click enter. Set up involves assigning your computer a static IP address which is a key to the communication between the converter and the computer. That’s all there is to it.
The bottom line
We reviewed two main ways to access remote serial port with COM over Ethernet Adapter. You may choose the hardware solution, but keep in mind that you will be limited by the cord length. The most simple solution seems to be to use the software RS232 to Ethernet Adapter. It requires no additional settings and devices and is simple in use. We hope this article assists you in choosing the appropriate solution for your usage needs.
