Before USB, serial connection ports served as the go-to method for hooking up equipment to a computer system. There are many different sizes of serial connections, with the 9-pin RS232 as one of the most popular. This cable hookup allows you to send data directly between printers, scanners and other hardware and the computer. If you are running an older computer system (Windows 2000 or earlier, typically) you probably have a 9-pin serial connection, without any USB ports. In order to sync up a USB device to the computer, you must convert the 9-pin RS232 cable connection to USB.
