Abstract
This chapter presents the details of a vast array of data acquisition hardware and software products. It also discusses the products from a few major manufacturers in detail, including operational details as well as how to use the products. A large number of manufacturers produce data acquisition hardware products for personal computers. The largest market is for MS-DOS PC/XT/AT platforms. Many data acquisition boards for personal computers (PCs) have dedicated functionality, such as analog inputs only. Some may have expansion capability, such as an additional multiplexer for more analog inputs. Other PC-based data acquisition cards are designed to be modular. Data communications interface cards are also important pieces of data acquisition system hardware. In this case, the personal computer is used as an intelligent controller, running remote data acquisition equipment through the interface. Data acquisition cards for PCs fall into several major functional categories, including digital I/O, analog I/O, and counter/timer. Some boards have most or all of these features; others have only one or a few.
