Relationship between Baud rate and CAN-bus communication Dis
So let look at the factors affecting the communication distance.
1st of all, Baud rate.
We all know, transmission distance and baud rate are inversely proportional. The communication distance can be up to 10KM (rate less than 5Kbps) and the rate can reach 1Mbps (communication distance is less than 40M).
Than what is the relationship between the Two?
Please see the table below:
So if you want a long distance, try to change the baud rate.
But in many cases, the lower baud rate means lower transmission rate. If this can't meet your requests, usually you need a CAN-bus repeater/relay.
Please see our GCAN-206, it is really a cost-effective CAN-bus repeater.
The CAN bus-repeater can realize the problem that the CAN signal becomes weak during the CAN bus signal transmission process. In addition, the ID filtering and data conversion functions are added. Since the CAN bus repeater is used for long-distance transmission of CAN signals, its anti-interference ability is very strong. If the user's device CAN bus is susceptible to interference, we can also increase the product to achieve the effect of isolation interference.
