Introduction RS-485 and CAN are both serial communication protocols. They allow for the arrangement of multiple devices within a single system, significantly reducing cable lengths. Their differential design is suitable for environments with strong interference, and both use 120 Ω termination resistors, equipped with internal over-voltage circuits for fault protection.RS-485 and CAN have many similarities, … Read more
In industrial applications, there are many bus application scenarios, such as the conversion between RS-232 and RS-485 with bidirectional isolation, and the sharing of RS-485 and RS-422 interfaces. This article will introduce solutions for such applications that are not only simple and convenient but also improve communication reliability. High-Performance RS-232 to RS-485 Bidirectional Conversion Circuit … Read more
RS-485 automatic transceiver circuits are favored because they use one less I/O pin compared to circuits with control pins, making them more popular in resource-constrained master control scenarios. How does the automatic transceiver achieve automatic sending and receiving, and what factors should be considered when selecting bias and termination resistors? RS-485 Automatic Transceiver Principle The … Read more
