A Practical Guide to Using RS-422 and RS-485 Serial Interfaces
The purpose of this ebook is to describe the main elements of RS-422 and RS-485 data communications systems. The authors have attempted to cover enough technical details so that personnel will have the necessary information to be successful in designing, modifying or troubleshooting an RS-422 or RS-485 data communication system.
Since both RS-422 and RS-485 are data transmission systems that use balanced differential signals, it is appropriate to discuss both systems in the same publication. Throughout this document the generic terms of RS-422 and RS-485 are used when referring to equipment and systems based on the EIA/TIA-422 and EIA/TIA-485 Standards.
