USB over Ethernet sharing technology - USB to Ethernet
It's a known fact that computers rely on USB devices to be able to interact with other consumer
devices. For industrial equipment, it's the same. No one can deny the fact that USB cable
remains an efficient means of transmitting data, as well a reliable way to establish
communication between peripherals and home PCs or large industrial servers. But what if the
need arises to connect to a device that is not within reach of the USB cable? Or share a piece of
equipment among several users? Is this even practical? Let's discuss that.
Get access to devices in the cloud
USB redirection challenge
Manufacturers of various USB hubs and USB to Ethernet adapters have long adopted the idea
of sharing one USB port among several users. With such hardware solution in place, you can
connect multiple devices to a single USB port on your computer at once. Or, simply put: you can
share USB over Ethernet
However, the major drawback regarding hardware products is that they lack special USB passthrough technology, which means they are either limited by the cable (USB hub) length or
become inefficient (USB over Ethernet connector). Also, it may be impossible to connect
physically to a USB port or requires the use of other hubs that may be expensive.
Manufacturers of USB hubs continually strive to ensure that their devices are exceptionally
valuable and they look for how to simply expand the functionality of their solution. Their main
aim is the provision of hardware products capable of sharing USB ports over Wi-Fi networks or
Integration of Cloud OS remote access
Here's where Eltima Port Virtualization (EPV) solution steps in.
With EPV technology, it's possible to virtualize and redirect USB devices over UDP or TCP
networks so they can easily be accessible to a remote client computer. The connection here is
achieved via a virtual USB port that is created in the client system. Consequently, EPV
technology makes it possible to share a USB device over Ethernet or allow a remote USB
device to be accessible to any network computer as if it was locally connected to the machine.
When you integrate the port virtualization technology into a USB to Ethernet adapter's operating
system, the hardware solution turns into a full-featured tool used to share USB device over
What are the benefits of the technology?
While the number of USB ports offered by many USB hubs is limited, Eltima software
technology allows you to set up as many virtual COM ports as you want on your PC.
Also, a shared USB device can be accessed by a limitless number of network computers. EPV
technology makes it possible for Ethernet connectors to have the edge over its main
competitors in the market. This allows manufacturers to acquire new market segments, increase
its customer base, and improve company revenues.
In turn, it offers end users flexibility they require in organizing their work process and reducing
