Today, most scientists and engineers are using personal computers with ISA, EISA, PCI, PCMCIA, Macintosh NuBus, or parallel or serial ports for data acquisition in laboratory research, test and measurement, and industrial automation. Many applications use plug-in boards to acquire data and transfer it directly to computer memory. Others use DAQ hardware remote from the PC that is coupled via parallel or serial port. Obtaining proper results from a PC-based DAQ system depends each of the components such as personal computer, transducers, signal conditioning, DAQ hardware, and software. This chapter defines the terminology common to each of the elements of a PC-based DAQ system. The hardware aspects of the system such as the signal grounding concepts have also been detailed. The digital IO techniques required for the DAQ assistant operation along with the installation and configuration details of DAQ are elaborated in this chapter.
This section explains the methodology to create analog input connections to achieve the optimum performance from the user's board. Prior to jumping into actual connection schemes, the...
