Access serial ports over SSL & SSH protected Ethernet!

Network connectivity for legacy serial devices!

NetBurner’s complete family of serial to Ethernet converters and device servers are ready to run right out of the box with no programming. The  setup, configuration, and diagnostic programs are easily accessed via the web page interface or included network utilities.

Serial to Ethernet web server and converter

The goal: Easily control, configure, or monitor a serial device using Ethernet.

The method: Connect serial port (COM port) to a NetBurner Serial to Ethernet device server.

The result: Access devices from the Internet or a Local Area Network (LAN) using SSH, SSL, or HTTPS.

What is a serial to Ethernet converter?

A serial to Ethernet converter (or device server) is a device that will take a serial data signal and send it out over a network connection. Additionally, it will take any network data received and turn it into a serial signal.

What is a serial to Ethernet converter used for?

A serial to Ethernet converter is used when you want to connect a serial device that isn’t network-enabled to a computer that either is too far away (sometimes halfway around the world!) or simply doesn’t have an appropriate serial port available.

Are serial to Ethernet converters secure?

This depends on the serial to Ethernet converter being used. For serial data being transmitted over a network connection to be secure, the converter needs to be able to support encryption with an SSL\TLS connection.

Can I use serial to Ethernet converters to allow two serial devices to connect over a network?

Yes, depending on the capability of the serial to Ethernet converter. This is called “serial tunneling“. To do this, you will need two serial to Ethernet converters, with each connected directly to a serial device. They will need to be configured to talk and listen to one another, but once they are set up, they will effectively send the data between the two serial devices as if they are directly connected by a serial cable.

What if an application on my PC needs a serial port, but doesn’t have one?

If an application on your PC is designed to talk directly to the serial device but your computer doesn’t have a serial port available, you will need to create a virtual serial port, also known as a virtual COM port. It will effectively act as a serial to Ethernet converter locally on your computer by taking your serial data and making it available over a TCP/IP connection. This is often used in conjunction with a serial to Ethernet converter, which receives the application data sent by the PC over a network connection and passes it along to the serial device that it is connected to.
