Summary Have you encountered occasional communication errors while debugging with the CAN or RS-485 bus? Or have you been unable to receive data? Did a bus that had been functioning normally suddenly experience widespread errors or node failures? If you are at a loss for these issues, using bus isolation might easily help you resolve … Read more
In applications such as CAN and RS-485, it is generally recommended to use shielded twisted pair cables for networking and wiring to reduce external interference on bus communication. Many engineers understand this recommendation but do not know the underlying reasons. This article will briefly introduce the principle of interference resistance in twisted pair cables. 1Differential … 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
Both CAN communication and RS-485 communication are commonly used communication methods in the field of industrial automation. However, the choice of communication method varies depending on the application scenarios. Therefore, selecting the appropriate communication method is one of the key factors that determine whether a product gains market acceptance. CAN Communication The CAN protocol, after … Read more

Upgrading the CAN transceiver to a CAN FD (Flexible Data-rate) transceiver is a complex process that requires careful planning, mainly involving hardware replacement and possibly software updates. Here are the detailed steps and considerations: 1. Hardware Selection First, we need to filter out the CAN controllers and transceivers that support CAN FD. CAN FD … Read more
CAN (Controller Area Network) bus protocol is a serial communication bus based on a message broadcasting mode, invented by BOSCH. It was initially used to achieve reliable communication between ECUs in automobiles and has since been widely applied in industrial automation, shipping, and medical fields due to its simplicity, practicality, and reliability. Compared to other … Read more
