In the Catalog for USB-232/485 Series Interfaces, it says that the 1-port interface has a USB Type A plug whereas the 2- and 4-port interfaces have a USB Type B connector. What is the difference? Do I need any additional hardware to connect either one to my computer? Solution: The USB receptacle on your PC is a type A connector and can be recognized by its rectangular shape.Type A receptacles can be found on upstream devices such as a USB host, or a hub. Type A plugs can be found on cables, and smaller peripherals such as a mouse and a flash drive. However, many larger USB peripherals such as printers and scanners use a detachable cable, and use the Type B receptacle, which has a square shape. Instruments are another type of downstream device. To connect an instrument to your PC, you will need to use a USB Type A to Type B cable. The two types of plugs have the same number of pins, and are electrically identical. They are only different mechanically.
