Serial extender: software and hardware solutions


Can you imagine people's lives without the many serial devices that satisfy people's evolving needs from day to day? COM port plotters, lab equipment, industrial controllers, payment terminals, and many other devices considerably simplify our everyday tasks. But what really makes the use of serial peripherals convenient is a dedicated RS232 extender which allows connecting to devices remotely. In this article, we'll consider both hardware and software solutions for sharing COM-based equipment over the network so that you can see which method is simpler and more efficient.

RS232 extender software

The solution is designed to redirect serial devices across the Internet (LAN, or Ethernet) this way making them accessible to multiple remote users at a time. The great thing about this RS232 extender over IP 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.

How to extend RS232 port with FlexiHub


  1. First, create your FlexiHub account. Then, select a suitable subscription plan.
  2. After that, you install the program on the computer (server) with a serial device attached and all client machines that will connect to the device remotely.
  3. Once done, you start the app on the server PC and a remote client and enter your FlexiHub account using the same credentials.
  4. In the software interface on the client machine, you'll see the devices available for connection. You simply choose the required one and click "Connect".

Starting now, you'll have full access to the device's functionality as though the peripheral were physically connected to your PC!

Hardware RS232 extender solutions

RS232 extender

Through the use of a hardware solution, you can extend the length of an RS232 line to 4,000 feet. A pair of extenders are used to accomplish this, with one connected to both ends of the serial line whose range you wish to extend.

The RS-232 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 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 over Cat 5 Extender. It enables you to remotely access serial peripheral equipment.

Installing the Extender is a simple task that can be done with Cat 5 or higher quality Ethernet cabling. It provides an economical, hardware-based solution to accessing serial devices remotely and offers full plug and play functionality.

The RS232 Serial over Cat 5 extender 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.
