9.1 Application Information

When designing a system that uses drivers, receivers, and transceivers that comply with RS422 or RS485, proper cable termination is essential for highly reliable applications with reduced reflections in the transmission line. Because RS422 allows only one driver on the bus, if termination is used, it is placed only at the end of the cable near the last receiver. In general, RS485 requires termination at both ends of the cable. Factors to consider when determining the type of termination usually are performance requirements of the application and the ever-present factor, cost. The different types of termination techniques include unterminated lines, parallel termination, ac termination, and multipoint termination.
