RS-485 (RS232 to RS485) bus interface, as an electrical specification for multipoint and differential data transmission, has become one of the most widely used standard communication interfaces in the industry. The RS-485 standard specifies only the electrical characteristics of the interface and does not involve connectors, cables, or protocols, allowing users to establish their own … Read more
The RS-485 bus is a commonly used field bus in industrial communications, but industrial control environments are often harsh, and the bus can be subjected to various external disturbances that affect its reliability. Among these, Electrical Fast Transient (EFT) disturbances are common. Today, we will discuss how to test and eliminate the impact of pulse … Read more
This article overview Have you encountered occasional communication errors when debugging with the CAN or RS-485 bus? Or are you unable to receive data? Has a bus that has been functioning normally suddenly started to exhibit widespread errors or node failures? Are you at a loss for how to address these issues? Using bus isolation … Read more
