The 576 is a general-purpose data acquisition and control device — an interface between a GPIB controller and countless research, industrial, and educational applications. With the 576, you can measure voltages, currents, and many other types of signals, as well as implement intelligent process control systems. The Model 576 is a complete system. It integrates hardware and documentation to make measurement and control technology easy to use. The Model 576 combines the most often used analog and. digital I/O functions into a single package. The Model 576 has two expansion slots, one of which is normally occupied by a master analog input module. This leaves one slot for other modules you might want to add. If your application does not require analog input, The Model 576 interfaces readily to many types of controllers, and is equally easy to operate. It includes ROM-based firmware and an easy-to-use programming language. The programming command set can be used with many language environments such as BASIC, C, and Pascal. In many cases, the controller will be a computer which is equipped with an IEEE-488 (GPIB) interface card. This includes a wide variety of configurations such as: • IBM PC, XT, AT, and PS/2 Personal Computers equipped with an IOtech, National, CEC, Metrabyte, or other IBM-compatible GPIB interface. • Apple Macintosh and Macintosh SE computers equipped with a suitable external GPIB interface (e.g. IOtech MacSCSI488, Mac488B). • Apple Macintosh II computers equipped with a suitable Nubus® GPIB interface (e.g. IOtech MacII488). • Most other computers which have an RS-232 or RS-422 compatible serial port. The Keithley500-Serial adapter will convert such ports to GPIB input/output. (If your computer is not listed, contact the Keithley Data Acquisition and Control Applications Support Group. Many possible methods exist for connecting the Model 576 to various computers.)
