The RS-485 bus is widely used in industrial environments, which may experience high levels of electrostatic or surge interference. Engineers typically use gas discharge tubes and TVS diodes to build protective circuits. However, these circuits have a high junction capacitance, which, if improperly applied, can affect communication. This article will introduce a low junction capacitance … Read more
The RS-485 bus has advantages such as a simple structure and low cost. However, when engineers set up RS-485 bus networks, they often encounter the question: should termination resistors be added to improve the reliability of the entire network’s communication? This article will answer that question. 1. The Role of Termination Resistors For the RS-485 … Read more
