channel. You require initialization access for the channel to configure the bus speed.
To configure a new bus speed:

Type the desired value in the Specify bus speed dialog box.

Click OK.
The value you set takes effect once you start the CAN channel. If an error occurs when
applying the new bus speed, the value reverts to the default value specified in the
hardware.
