The PC Family,urers throughout the world. The original components of the PC have been upgraded several times during the last few years, so that while the early models may have had an 8088 processor, 128k RAM and one low capacity floppy disk, later models are more likely to have an 80286 processor, 640k RAM, a hig

Parallel Standard Interface Systems, be passed from one to the other. In the computer context a standard interface system can be viewed as consisting of the elements illustrated in fig 8.1. The “system” actually consists of two interface units - the computer interface and the device interface. To allow for digital signal transfer betw

The Serial Standard Interface and Communication System,elephone system and one of these has become popular for the connection of peripherals, such as microcomputers or printers, to laboratory instruments. This is the RS232 standard of the Electronic Industry Association, which has undergone two revisions and in its present form is called the RS232C stan

The Basics of Laboratory Signals,ngle, velocity or acceleration. However, virtually all such physical characteristics may be converted into some form of electrical signal by an appropriate energy conversion device known as a transducer. Some typical transducers are listed in table 2.1, along with the nature of the particular energy stimulus for which each is designed.

Parallel Standard Interface Systems,een the two, the “standards” are primarily concerned with the characteristics of the signals involved - their number, signal levels, impedances, timings etc. - rather than with the actual electronic circuits in either interface, although some characteristics of the latter may be important.

System Design and Case Study,e standard reaction is: “Cut the philosophy - let’s get on and make something.” The number of times that this is followed, eventually, by “We can’t make it do that - we would have to rewrite the whole thing.” or “We can’t measure that as well - there are no spare address lines,” convinces me that this chapter should be the most valuable of all.
