What is the difference between RS485 and RS422?

All of our RS422/RS485 products can electrically accept either RS422 or RS485. However, RS485 is a “bus” type architecture which requires that devices on the "bus" only respond when requested on a an additional line (CTS). Our products do not have that line because navigation / inertial product data requires 100% use.
