The implementation on the software side is not much more difficult than with

RS232. It is the reason why RS485 is so popular with computers, PLCs, micro

controllers and intelligent sensors in scientific and technical applications.

Figure 2-11 illustrates the multiple-transceivers RS-485 which is going to be

implemented. It is important to keep the distances from the twisted pair to the receivers

as short as possible.

2.5. Knowledge of the required software and hardware

As the knowledge on the software as well as the several devices used were null

and never used before, it has been necessary to take advantage of either the help of the

corresponding software or manuals found in internet mentioned in the reference section.

Appendix E illustrates all the information about the necessary software and devices.
