Automatic identification of the baud rate
If you don’t know the baud rate, you can choose automatic identification of the baud rate.

There are two modes of the function, silent mode recognition and enhanced mode recognition.
The environment for silent mode recognition requires active CAN data on the bus. The CAN-Bus has at least two devices under test and can communicate with each other normally. The environment for enhanced mode recognition are the CAN device must be powered on and the CAN channel is working properly. It does not require the device to actively send CAN data, nor does it require active CAN data on the bus. Please make sure the connection is correct and two 120 ohms resistance is on the CAN-Bus.
Please note that for the CAN-Bus system of the car, please select “silent mode recognition” to identify the baud rate. Using “enhanced mode recognition” may result in vehicle instrument error reporting.

here we use USBCAN-II Pro to detect unknown baud rate of other equipment. The wiring method is CANH to CANH, CANL to CANL and the resistance dial switch has been switched down. Then open ECANTools.
The baud rate automatic recognition function is divided into two modes:
A. Standard baud rate identification
B. Full range baud rate identification

A. Standard baud rate identification
The user can identify the standard baud rate such as 1000k, 800k, 666k, 500k, 250k and so on.

B.Full range baud rate identification
If the unknown equipment’s baud rate is not standard, users can use the full range baud rate identification which is all baud rate in the user selection range.
