What is Serial over Ethernet?

Serial over Ethernet is an extension of serial connections that enables data transfer between RS232, RS422, and RS485 interface devices over Ethernet. It is achieved by converting and encapsulating serial data to Ethernet packets and transmitting them over the network to the remote computers.

FlexiHub provides the ability to access serial ports over Ethernet and offers high-speed connections and secure data transfer.
access serial ports over Ethernet

The software offers an effective method of implementing serial communication over Ethernet without the addition of extra hardware or cables.

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.

Features of Serial over Ethernet software

Communications over a private server

FlexiHub offers a one-of-a-kind feature called Redirection Server. It allows connecting serial ports over the network between computers that do not have a public IP address. It means that connecting Ethernet COM ports from different subnetworks is possible with a few clicks without the need for configuring any additional settings.

Encrypted channels for data transfer

Thanks to the 2048-bit SSL encryption used by the software, you can be sure that all data sent by virtual serial ports over Ethernet will stay safe and won’t be acquired by any third party.

Virtual serial port functionality

Advanced COM port redirection technology is at the heart of FlexiHub and is the key to sending serial data over Ethernet. It creates virtual network serial ports and makes them available to remote users.

Serial redirection over the UDP protocol

When a direct connection between two nodes is not possible, FlexiHub may use a UDP channel and UDP hole punching technique to let two computers that are hidden behind NATs connect successfully.

How to access serial over Ethernet

To start sharing serial devices and connecting them to virtual serial ports over Ethernet, you will need:
1
Firstly, register your FlexiHub account. Then, select a subscription plan that will best fit your needs to start a free demo period.
 Register a FlexiHub profile
2
After that, install the software on the computer (server) with a serial device physically connected and the remote computer (client) that will access that device remotely.
 Download Flexihub
3
Start the software on both machines and log into your account using the same credentials. In the app’s interface on the client computer, you will find the list of devices available for connection.
 Login flexihub

All you need to do is select the peripheral that you’d like to connect to and click the “Connect” button, and this is it! Now, you can manage the device as if it were attached to your computer physically.

Serial to Ethernet software areas of use

Redirecting serial devices to virtual machines

Accessing the local serial ports of the host machine from within a virtual environment can be notoriously difficult. The complicated configuration is necessary to enable the redirection of the serial devices to virtual machines: Hyper-V, VMware, etc. FlexiHub removes those complications and offers a streamlined method of attaching locally-attached peripheral devices to virtual sessions in just a few clicks.

Improving industrial automation processes

Enhanced productivity can be achieved by connecting serial devices over IP where they can be monitored and controlled from a centralized, remote location. Both improved employee safety and reduced costs can be the result of implementing the connectivity of a facility’s RS232, RS422, and RS485 devices. Using serial over Ethernet technology, all of the robots, controllers, sensors and actuators can be redirected over Ethernet to the main data server.

Configuring IT equipment via Ethernet

Accessing remote serial ports of IT equipment is another valid use of serial over Ethernet software, which enables remote firmware updates or configuration changes. Traditionally, this needed to be done with a direct connection and console cables. By virtualizing the physical serial ports of routers, switches, and hubs, the devices can be accessed by a computer with serial over Ethernet capability.

Connecting medical equipment over Ethernet

Remote access to critical medical equipment introduces more flexibility in the placement and utility of the various monitors, nurses’ stations, and laboratories. With virtual serial over Ethernet connection, information from anywhere in the facility can be collected in a central location where it is available to the complete medical staff.

Serial to Ethernet Converters: Hardware Solution

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.

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 local and remote devices.

Limitations:

  • Port Limitation: The number of devices that can be shared is limited to the number of serial ports available on the hardware.
  • Alternative Solution: For remote access to a large number of COM port devices simultaneously, consider a software solution like FlexiHub, which supports an unlimited number of serial peripherals.
