Testing Items and Methods for RS-485

Any communication interface testing includes two parts: basic electrical characteristic testing and stress testing. RS-485 is no exception. The common tests for RS-485 primarily focus on electrical characteristic testing and stress testing. The first part: Electrical Testing. For electrical testing, we generally combine some parameters from the chip manual for testing. The following figure shows … Read more
