We’ll talk about what devices it’s compatible with, as well as how to set it up. To fully understand how this adapter works and what it’s capable of, we’ll have to dig deeper. But that’s just the bare minimum of what you need to know. This is a 4-port RS232 hub, which connects to your computer via USB.

With that in mind, we’re about to review the DriverGenius 4XRS232 4 Port USB to DB9 RS232 Serial Adapter Hub. If RS232 is still good enough for the job, industrial machines will still use it.īut what if you want to control an RS232 device with a modern computer? In most cases, you’re going to need an RS232 to USB adapter. But industry likes tried and true technology. For home use, RS232 has been obsolete for some time, superseded by the more-versatile USB standard. Not only that, but it found a home in industrial applications, for connecting manufacturing and tooling machines. As PCs became mainstream, it became a favored standard for connecting all kinds of peripherals. RS232 was first used in the 1960s for accepting computer inputs from electromechanical keyboards. One of the oldest – and most enduring – serial connections is RS232. As a result, there’s a healthy market for adapters, hubs, and other devices to aid in connectivity. There have been a number of standards throughout there years, used for all different kinds of purposes. Not only that, but USB is only one kind of serial connection. And within those, there are various standards, such as USB 2.0, 3.0, and 3.1.

There’s standard USB (Type-A), there’s Type-B, Type-C, Micro USB, and even Mini USB. USB is an excellent example the “U” literally stands for “universal,” but it’s far from universal. Over time, few things about computers have remained less consistent than wiring standards.
