CAN communication bus related issues
Topic 1: Is the CAN communication bus device with metal shell more expensive and more powerful than the plastic shell?
Answer: This statement is actually one-sided, because the CAN communication bus device is a collective name, it includes USBCAN analyzer, CAN data conversion gateway, CAN data storage, CAN data repeater and many other types, each category has It may be metal or plastic. Can you simply say who is stronger than who? Even for tools of the same category, the metal case is not necessarily stronger than the plastic case. It depends on the circuit board inside to see who is more powerful. The case is just a protection device. The role of the software is also very large, can not be ignored, the role of the shell is actually the smallest. Some friends may say that the metal shell is stronger than the plastic shell, less susceptible to damage, and more textured. However, if all the circuit boards inside the case are missing parts, what is the use of the case no matter how strong it is? At present, the plastic shells used for CAN communication bus devices are basically engineering plastics with both hardness and toughness. Ordinary bumps will not hurt them. If they really decline from a particularly high place, they may be broken. The original, metal shell will not work! Therefore, in the end, choose the CAN communication bus device with a metal shell or a plastic shell, please choose according to your actual needs and preferences.
Topic 2: Do all CAN communication bus devices need to be connected to a computer?
Answer: Of course not, but before use, almost all CAN communication bus devices should be configured with relevant parameters through the computer, and then offline offline, directly connected where needed, at this time, as long as the physical layer is connected correctly, the wave There is no problem with the rate setting. If the 120-ohm resistor is incorporated, the related equipment can work normally. The next time we face different needs, we can reconfigure the equipment, depending on your specific needs.
