What is the maximum transmission speed of the CAN Bus Controller?

The maximum transmission speed of the CAN Bus Controller is 500 kbauds.

How does the CAN Bus Controller handle termination resistance?

The controller has an integrated bus termination resistor, which can be activated by connecting a jumper between pins 1 and 2.

What is the maximum distance for the CAN Bus Controller's communication interface?

The maximum distance for the CAN communication interface is 1000 meters.

How does the CAN Bus Controller indicate a power overload?

The controller indicates a power overload by a flashing orange LED with a double pulse, suggesting that the total power of the modules exceeds the controller's supply capacity.

Is the CAN Bus Controller certified for safety and compliance?

At the time of the manual's publication, the CAN Bus Controller was in preparation for C-UL-US certification.
