What is Serial to Ethernet converter?
RS-232 to Ethernet converter is a hardware appliance that redirects serial devices over the network by transforming serial input into TCP/IP data and vice versa. It is also sometimes called a Serial to Ethernet adapter. A standard Serial to Ethernet converter may have from 1 to 20 serial ports embedded in it, so up to 20 serial peripherals can be shared at a time. With that, the hardware tool is rather easy to install and use, which makes it a convenient way to forward your fancy RS-232 port to a remote network machine.
How to use Serial to Ethernet adapter?
The RS-232 to Ethernet Extender provides connectivity to serial devices within 1,000 feet of your machine with only standard Cat5 networking cables. One scenario is to use the RS-232 to Ethernet Extender to connect with a local device and use a Cat5/5E UTP cable to reach a remote piece of equipment. One DB9 port is available on the local and remote devices.
Connect to RS232 serial devices and applications over increased distances by using a Serial to Ethernet Extender. It enables you to remotely access serial peripheral equipment.
To use Serial to Ethernet adapter you need:
- When you buy a serial to Network adapter, together with the hardware tool you get a driver known as a virtual COM software. The first step will be to install the software on a client computer.
- Once the software is installed, connect the hardware to the client PC with a standard Ethernet cable. Next, connect the converter to the power supply.
- After that, put the IP of the hardware into your browser’s address bar and hit ‘Enter’. Configure the converter to access it from your computer.
- Now, any serial device plugged into your converter’s serial port will appear in the Device Manager of your computer’s OS.
Flexihub - Serial to Ethernet converter software
The simplicity and speed of this nicely designed app are stand-out. All connections created with the software are protected with advanced encryption, so FlexiHub is basically a super secure way of sharing serial devices over LAN, Ethernet, or the Internet. Plus, the solution is well-suited for those who want to access a number of remote serial peripherals simultaneously.
The great thing about this RS232 to Ethernet extender is that its interface is really simple and intuitive. Just a couple of clicks is enough to share a COM peripheral over any distance. In addition, FlexiHub takes the leading position when it comes to the security of connections. The app uses advanced encryption which reliably protects all network communications established with the help of the software.
To use FlexiHub as RS-232 to IP converter you need:
Serial to Ethernet Connector
The other handy software solution is Serial to Ethernet Connector. It works under Windows and Linux, would be a great software alternative to FlexiHub. The software will allow you to implement various scenarios, like sharing one or multiple serial devices to one or many clients and vice versa, connect two serial applications via a virtual null-modem cable over the network or redirect serial devices to the virtual environment.
How to use Serial to Ethernet Connector
- Download Serial to Ethernet Connector to install on a computer with a serial port to share and also on a computer that will access the port.
- On a computer with the port to redirect choose the “Server connection” in Serial to Ethernet Connector. After customizing the settings click "Create connection" in the Main window.
- Open local COM port.
- On another computer that will be connecting to the shared port create a “Client” connection. Make sure that remote hostname and port number are the ones you've set in server machine configuration.
- Click 'Connect' on the remote computer and access the shared port with device as if it was connected directly to the computer you are working with.
List of best Serial to Ethernet converters
Hardware serial over Ethernet solutions are often delivered together with virtual COM applications. The dedicated software helps you create virtual serial interfaces which are recognized by your system and serial devices as standard ones.
The RS232 to Ethernet adapter employs the RS232 protocol to allow you to exert remote control over security devices, industrial monitors, and point of sale equipment as weak as any other serial peripheral.
Using a hardware serial extender is not the optimal way to address the issue of remotely accessing your devices. A software solution is not subject to the same distance limitations as a wired or wireless hardware extender. Another disadvantage of using hardware is that when using cables of over 200ft, the connection may be impacted by electrical interference.
But if you think that a hardware RS-232 to Ethernet adapter will perfectly fit for your workflow, we’d like to tell you about the four most popular serial port extenders available today.
Serial to Ethernet converter by NetBurner
NetBurner Serial to Ethernet converter is an efficient solution for communicating with COM port devices over Ethernet network. This hardware serial port redirector can easily share up to 4 COM port devices. In order to configure your network connections, you should use a software app which comes included with the hardware. Here’s how it works: you simply connect your serial port device to the NetBurner Serial to Network adapter and access it over LAN as though the device were physically attached to your remote PC.
RS232 to Ethernet converter
Perle has developed a great RS232 to Ethernet converter that ensures reliable data transmission over an IP network. This hardware is a simple way to remotely access your RS232 devices. The converter offers intelligent packet structuring and forwarding of data, so you can control the way your data is sent over Ethernet. The key advantages of this convenient tool are the ability to match the communication specifications of your serial devices and a built-in serial line trace capability.
Serial-to-Ethernet Adapter by SeriaLynx
If you need to get remote access to serial devices like scoreboards, time clocks, and wind gauges, it will be a good idea to try Serial-to-Ethernet adapter by SeriaLynx. The solution enables wired or wireless connections to two serial devices over a LAN using TCP-IP mapping. You can attach up to two serial devices to the adapter’s COM ports, connect the hardware to Ethernet via a wired Ethernet port, or share the devices over the network with the help of an antenna for broadcasting over an 802.11 wireless network, and that’s it! You gain access to the remote devices from any computer connected to the same network.
Lantronix UDS1100 external device adapter
UDS1100 is a small hardware converter able to redirect one serial device over LAN or the Internet. The converter can be configured via HTTP, DHCP, Telnet, serial or Lantronix DeviceInstaller app. The solution is fast, reliable and easy to install. By using this tool you can share, monitor and control RS232, RS422 and RS485 equipment over Ethernet quickly and effortlessly.
The main downside of the hardware solution, however, is that the number of devices it can share at a time is limited to the number of serial ports the hardware fits. In case you need to remotely access a big number of COM port devices simultaneously, a good idea will be to try a software solution like FlexiHub which works with an unlimited number of serial peripherals.
