The importance of CAN bus terminating resistors
With the increasing popularity of CAN bus in all walks of life, USB CAN has also become the mainstream of CAN bus equipment, and is widely used in automotive electronics, industrial and other control fields. CAN bus can be developed, tested, managed and maintained for CAN network. , record, send and receive and analyze CAN bus data.
But when we look at the internal structure of USB CAN, we may find that there is a 120-ohm resistor on the core board. Let's take a look at the function of the 120-ohm resistor.
The 120 ohm resistor in USB CAN can be said to be indispensable. In USB CAN, this resistor can provide a stable physical link and can also absorb the reflection of the endpoint.
When we use USB CAN to perform the self-transmitting and self-receiving test of a single node, there must be a 120 ohm resistance, and we need to make it form a complete loop so that the self-transmitting and self-receiving test can be completed, otherwise it cannot be achieved.
We also need to know that every detail design of the USB CAN device is the result of thousands of tests and the final result. This is also an industry standard specified by default for the safety of the CAN bus.
