Hi

See one of the attached examples about how to configure the baudrate.

I have been accroaded refernece to configure, but the baudrate is not 125000? why

[DirkW]

Hi,

For the channel api the baudrate is configured in MAX (measurement and Automation Explorer) by default. If you need to change the baudrate programaticaly, you need to call the 'set attribute" function to set the bautrate explicitly.

For the frame api the baudrate becomes configured within the configuration struct.

 My configure is below:

AttrIdList[0] =  NC_ATTR_BAUD_RATE;  
 AttrValueList[0] = 125000;

Is it OK?But the transmission's baudrate is 230K~270K why? or configure hardware?

Hi,

How do you know that your baudrate is between 230 and 270K?

Normaly the baudrate does not change or vary. If the config struct uses 125K it should configure the port like that.

Perhaps you could run the NI SPY together with your code. The SPY logs the api calls to NI CAN. Save the log file and post it to this thread.

That may be helpful.

use CAN Oscilloscope Measure baudrate is 230K~270K
