Connect USB- Adapters and Converters
However, for less exotic computer applications, there are a huge variety of USB converter and adapter cables which allow many different devices to be plugged into a USB port. A good example of one of these is a USB to Serial cable. Most modern PCs are no longer shipped with 9 or 25 way serial ports. While this may not be a problem for most office and home users, it can be an issue for user who need to connect to older EPOS, laboratory and process control equipment, especially as these kind of devices are often not easy (or cheap) to update or replace. A USB to Serial converter cable is a simple, low cost solution for this kind of application.
Similarly, if you’ve got a faithful old printer or plotter in your office, USB to Parallel converters are available to allow you them to remain in use when your computers are updated.
It’s not just older devices which can be connected using USB converter cables though. It’s also possible to connect more modern ‘non USB’ equipment. For example, monitors and projectors can be connected to USB ports. There are many USB to VGA and USB to DVI cables on the market today. These are an especially useful solution for laptop users who need to connect to multiple monitors.
For audio and recording applications, USB audio cables are also available. These cables allow users to connect to an instrument or microphone to a computer for home recording.
These are just a few examples of the many USB converters and adapters that are available. As you can see, there’s much more to the simple USB cable than just a lead to plug into your printer. However unusual your device, if you look hard enough, there’s probably a USB converter cable that will connect to it!
